(b) g(g(3))
Use f(x) = 5x - 4 and g(x) = 2x2 to evaluate the expression.
(a) f(f(2))
how do i solve this?
Answer:
324
Step-by-step explanation:
To evaluate (a) f(f(2)), we first evaluate f(2) which is 52-4 = 6. Then, we evaluate f(6) which is 56-4 = 26. So, f(f(2)) = 26.
To evaluate (b) g(g(3)), we first evaluate g(3) which is 23^2 = 18. Then, we evaluate g(18) which is 218^2 = 324. So, g(g(3)) = 324
A baseball coach purchased bats and batting helmets. The coach purchased 19 items in all. Each bat cost $18.25 and each batting helmet cost $24.50. If the coach spent a total of $396.75, how many bats did the coach purchase?
Answer:
11 bat and 8 helmets.
Step-by-step explanation:
Let x = the number of bats
Let y = the number of batting helmets
x + y = 19 Rewrite as y = 19 - x
18.25x + 24.50y = 369.75 Multiply by 100
1825x + 2450y = 36975 Substitute 19 - x for y
1825x + 2450(19 -x) = 39675 Distribute the 2450
1825x + 46550 - 2450x = 39675 combine like terms
-625x + 46550 = 39675 subtract 46550 from both sides
-625x = -6875 Divide both sides by -625
x = 11
He bought 11 bats
x + y = 19 Substitute 11 for x to solve for y
11 + y = 19 Subtract 11 from both sides
y = 8
He bought 8 helmets.

Step-by-step explanation:
The slashes through the lines indicate they're of the same length, which means this is an equilateral triangle. Therefore all three angles are 60 degrees.
The lines being parallel mean that angle x shares the same angle as the triangle in the bottom-right corner.
The parallel lines intersecting with the line segment that is consistent throughout the triangle makes the angle the same.
Step-by-step explanation:
We can see that the triangle in the picture is an equilateral triangle, because its sides are all marked with one dash, meaning they are equal lengths. We note that all the angles in an equilateral triangle are each 60°.
The little arrows on the top and bottom lines in the figure indicate that they are parallel, which means that the diagonal line between them creates a set of alternate angles (I've attached a pic of what alternate angles generally look like to make this clearer).
Alternate angles are equal, which means x is equal to the angle at the bottom right of the triangle, which is 60°.

The y-coordinate for the solution to the system of equations is y = -3.
What is substitution method?The substitution method is typically used in mathematics to solve an equation system. In this approach, you solve the equation for one variable first, then you enter its value into the other equation.
Simultaneous equations may usually be solved easily using the substitution method. There are direct ways that can give you the value of the unknown variables, such as cross-multiplication techniques. However, this method can be chosen over other algebraic methods for straightforward equations that don't require complicated calculations.
The system of equation is given as:
y = 1/2x - 4
y = -2x + 1
Substituting the value of y in equation 1 we have:
-2x + 1 = 1/2x - 4
-2x + 1 = x - 8 / 2
(-2x + 1)(2) = x - 8
-4x + 2 = x - 8
2 + 8 = x + 4x
10 = 5x
x = 2
Substituting the value of x in the second equation:
y = -2(2) + 1
y = -4 + 1
y = -3
Hence, the y-coordinate for the solution to the system of equations is y = -3.

Use the Empirical Rule. The mean speed of a sample of vehicles along a stretch of highway is 70 miles per hour, with a standard deviation of 3 miles per hour. Estimate the percent of vehicles whose speeds are between 64 miles per hour and 76 miles per hour.
Answer:
The Empirical Rule states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% of the data falls within two standard deviations of the mean, and approximately 99.7% of the data falls within three standard deviations of the mean.
In this case, the mean speed is 70 mph and the standard deviation is 3 mph. So, we can estimate the percent of vehicles whose speeds are between 64 mph and 76 mph as follows:
64 mph = 70 mph - 3 mph * 1
76 mph = 70 mph + 3 mph * 1
Since the speeds are within one standard deviation of the mean, we can use the Empirical Rule to estimate that approximately 68% of the vehicles have speeds between 64 mph and 76 mph.
So, the answer is approximately 68%.
Mary invests £12000 into a savings account. The account 1.5% compound interest per year. Work out the value of her investment after 2 years.
Answer:
Step-by-step explanation:
To calculate the compound interest on Mary's savings account, we can use the formula:
A = P * (1 + r/n)^(nt)
Where:
A is the amount after t years
P is the initial principal (£12000)
r is the interest rate (1.5%)
n is the number of times the interest is compounded in a year (let's assume it's compounded annually)
t is the number of years (2)
So, plugging in the values, we get:
A = £12000 * (1 + 0.015/1)^(1 * 2)
A = £12000 * (1.015)^2
A = £12000 * 1.0302
A = £12363.84
So, after 2 years, Mary's £12000 investment would be worth £12363.84, including the compound interest.
¿Que probabilidad hay de que al lanzar dos dados la suma sea 11 en la primera tirada y 5 en la segunda?
Answer:
Step-by-step explanation:
The probability of rolling a sum of 11 on the first roll of two dice is 1/36, as there is only one combination of dice that can add up to 11 (a 5 and a 6).
The probability of rolling a sum of 5 on the second roll of two dice is also 1/36, as there is only one combination of dice that can add up to 5 (a 1 and a 4).
The probability of two independent events occurring is equal to the product of their individual probabilities. So, the probability of rolling a sum of 11 on the first roll and a sum of 5 on the second roll is:
1/36 * 1/36 = 1/1296
So, the probability of rolling a sum of 11 on the first roll and a sum of 5 on the second roll is 1/1296.

Find
r(2)
Answer:t he autocorrelation of the time series X at lag 2 is approximately -0.018.
Step-by-step explanation:
To find the autocorrelation of the time series X at lag 2, we need to calculate the covariance between X(t) and X(t-2). This can be done using the following formula:
r(2) = cov(X(t), X(t-2)) / var(X(t))
where cov(X(t), X(t-2)) is the covariance between X(t) and X(t-2), and var(X(t)) is the variance of X(t).
To calculate the covariance, we'll use the following formula:
cov(X(t), X(t-2)) = sum((X(t) - mean(X(t))) * (X(t-2) - mean(X(t-2)))) / (n - 1)
where n is the number of observations in the time series. To calculate the variance, we'll use the following formula:
var(X(t)) = sum((X(t) - mean(X(t)))^2) / (n - 1)
First, let's calculate the mean of X(t):
mean(X(t)) = (47 + 64 + 23 + 71 + 38 + 64 + 55 + 41 + 59 + 48) / 10 = 51
Next, let's calculate the covariance between X(t) and X(t-2):
cov(X(t), X(t-2)) = sum((X(t) - 51) * (X(t-2) - 49)) / (10 - 1) = -10.3
Finally, let's calculate the variance of X(t):
var(X(t)) = sum((X(t) - 51)^2) / (10 - 1) = 563.7
Plugging in these values, we can find the autocorrelation at lag 2:
r(2) = cov(X(t), X(t-2)) / var(X(t)) = -10.3 / 563.7 = -0.018
So the autocorrelation of the time series X at lag 2 is approximately -0.018.

It is important to know what the variables in interest-rate formulas represent.
Compound Interest: A = P(1 + F)nt
Continuously Compounded Interest: A = Pert
Write the variable in the blank next to its description.
Answer:
Step-by-step explanation:
In the compound interest formula: A = P(1 + r)^t
A represents the amount of money in the account at the end of the term t, including interest.
P represents the initial principal, or the amount of money invested.
r represents the interest rate, usually expressed as a decimal.
t represents the number of time periods over which the interest is compounded.
In the continuously compounded interest formula: A = Pe^(rt)
A represents the amount of money in the account at the end of the term t, including interest.
P represents the initial principal, or the amount of money invested.
r represents the interest rate, usually expressed as a decimal.
t represents the number of time periods over which the interest is compounded.
So the variables in the formulas and their descriptions are:
A: the amount of money in the account at the end of the term t, including interest
P: the initial principal, or the amount of money invested
r: the interest rate, usually expressed as a decimal
t: the number of time periods over which the interest is compounded.
Six more than one-fifth of a number p is equal to a number k.
Step-by-step explanation:
We can start by using an equation to represent the given information. Let's call the number p, and the number k, then:
k = (1/5)p + 6
So, "six more than one-fifth of a number p is equal to a number k" can be represented mathematically as k = (1/5)p + 6. To find the value of p, we can solve for p:
p = 5k - 30
So, p is equal to 5 times the value of k minus 30.

A. The indifference curve of a consumer is negatively sloped to the right because it represents the consumer's preference for one good over another. As the consumer's income increases, their willingness to substitute one good for the other increases.
B. The indifference curve is convex to the origin because it shows the diminishing marginal rate of substitution of the two goods. As the consumer reaches the optimal combination of goods, the marginal rate of substitution between the two goods decreases.
C. Using the Lagrange method, the optimum combination of goods can be determined as follows:
Let L(X,Y) be the Lagrangian of this problem:
L(X,Y) = √X² + Y² - λ(200 - 3X - 4Y)
Where λ is the Lagrange multiplier.
The optimal solution is obtained by setting the derivatives of L with respect to X and Y to 0 and solving the equations simultaneously.
∂L/∂X = 0 -> X = 11.85
∂L/∂Y = 0 -> Y = 8.57
Therefore, the optimum combination of goods is X = 11.85 and Y = 8.57.
D. The slope of the indifference curve is equal to the slope of the budget line. This can be shown by comparing their respective equations and noting that their slopes are the same. The equation for the indifference curve is Y/X = (-2/3) and the equation for the budget line is Y/X = (-3/4). Since these equations are the same, it follows that the slopes of the two lines are equal.

The mean of the given data is 1744 days, median of the given data is 1460.5 days, mode of the given data is 1461 days & 4422 days.
To find the mean, median, and mode of the lengths of terms of the US Presidents that preceded Joe Biden:
Mean:
To find the mean, we add up all of the term lengths and divide by the total number of terms:
Mean = (4422 + 2922 + 2865 + 2840 + 2728 + 2041 + 2027 + 1886 + 1654 + 1503 + 1461 + 1460 + 1430 + 1419 + 1262 + 1036 + 969 + 895 + 881 + 492 + 199 + 31) / 44
Mean = 1743.77 days
Median:
To find the median, we need to arrange the term lengths in order from smallest to largest, and then find the middle term. In this case, since we have an even number of terms, we will take the average of the two middle terms:
31 199 492 881 895 969 1036 1262 1419 1430 1460 1461 1503 1654 1886 2027 2041 2728 2840 2865 2922 4422
Median = (1460 + 1461) / 2
Median = 1460.5 days
Mode:
The mode is the most frequently occurring term length. In this case, there are two modes: 1,461 days and 4,422 days.
Since the term length of FDR is much higher than all the other term lengths, it has pulled up the mean to a higher value than the other measures of central tendency. Additionally, the mode being a high value is likely due to the fact that FDR served for more than three terms, which is an outlier in the data set.

Find the lengths of the sides of a triangle if two of the sides are equal, the third side is 1 1/3 cm longer than the others, and its perimeter is 5 2/5 cm. The two equal sides of the triangle are (blank)cm. The third side is (blank) cm.
Answer:
Step-by-step explanation:
Here's a step by step solution with more details:
Let's call the length of the two equal sides of the triangle as x.
The third side, which is 1 1/3 cm longer, will have a length of x + 1 1/3 cm.
The perimeter of the triangle is 5 2/5 cm, so we can write an equation using the lengths of the sides:
x + x + (x + 1 1/3) = 5 2/5
Simplifying the equation:
2x + 1 1/3 = 5 2/5
Subtracting 1 1/3 from both sides:
2x = 4 1/5
Dividing both sides by 2:
x = 2 2/5
So the two equal sides of the triangle are 2 2/5 cm and the third side is 2 2/5 + 1 1/3 = 3 7/15 cm.

5[tex]\frac{2}{5}[/tex] = [tex]\frac{27}{5}[/tex]
Let
x = one of the two equal sides of the triangle
∴ Third side of triangle = [tex]\frac{4}{3} + x[/tex]
Perimeter of a triangle = Sum of all three sides:
[tex]\frac{27}{5}[/tex] [tex]= x + x + (\frac{4}{3} + x)[/tex]
Expand the parenthesis using the Distributive Law and bring all the like terms together:
[tex]=\frac{27}{5} = 2x + \frac{4}{3} + x[/tex]
[tex]= \frac{27}{5} = 3x + \frac{4}{3}[/tex]
[tex]= \frac{27}{5} -\frac{4}{3} = 3x[/tex]
The two denominators of the two fractions have to be manipulated to be made the same:
[tex]= (\frac{3}{3})(\frac{27}{5}) - (\frac{5}{5})(\frac{4}{3}) = 3x[/tex]
[tex]= \frac{81}{15} - \frac{20}{15} = 3x[/tex]
[tex]= \frac{81 - 20}{15} = 3x[/tex]
[tex]= \frac{61}{15} = 3x[/tex]
Cross-multiplication is added:
[tex]= (61)(1) = (15)(3x)[/tex]
[tex]= 61 = 45x[/tex]
Isolate x and make it the subject of the formula:
x = [tex]\frac{61}{45}[/tex]
x = One of the two equal sides = [tex]1\frac{16}{45}[/tex]cm
∴Third side:
= [tex]\frac{61}{45} + \frac{4}{3}[/tex]
= [tex]\frac{61}{45} + (\frac{15}{15})(\frac{4}{3})[/tex]
= [tex]\frac{61}{45} + \frac{60}{45}[/tex]
= [tex]\frac{61 + 60}{45}[/tex]
= [tex]\frac{121}{45}[/tex]
= [tex]2\frac{31}{45}[/tex]cm

d. (5, 13) is not a solution to y ≥ 12 - x
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
A Set of such values is called a solution set to the considered equation or inequality.
Substitute the values where the variables are, and simplify to the point where you can tell whether the statement is true.
Each ordered pair is (x, y), thus the first value gets substituted for x; the second value gets substituted for y.
a. (2, 10)
11 < 13 -2 = 11
no
b.(3, 13)
8 ≤ 16 -3 = 13
