D: {-5, -2, 1, 2}
R: {-4, 0, 3}
The relation is a function
Explanation:Given:
5) Ordered pairs on a coordinate plane
To find:
the domain, range, and the type of relation
[tex]\begin{gathered} The\text{ domain is the input of a funcion \lparen x values\rparen} \\ The\text{ range is the output of the function \lparen y values\rparen} \end{gathered}[/tex]To determine the domain and range, we will list the ordered pairs:
(-5, 3), (-2, -4), (1, 0), (2, 3)
The first number in each pair represents the x values (domain), while the 2nd number in each pair represents the y values (range)
The domain: {-5, -2, 1, 2}
The range: {3, -4, 0, 3}
Rearranging and picking one of the repetitions:
The range: {-4, 0, 3}
For a relation to be a function, each input will have only one output.
None of the inputs appears more than once. Hence, each input has only one output. It is a function
Neveah orders a square pizza. 2/3 of the pizza has pepperoni. 2/3 of the pepperoni also has
green peppers. How much of the whole pizza has both pepperoni and green peppers?
The fraction of whole pizza has both pepperoni and green peppers exists 1/2.
What is meant by a fraction?A number is stated mathematically as a quotient, where the numerator and denominator are divided. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction exists less than the denominator.
Given that:
3/4 of the pizza contains pepperoni
2/3 of the pizza with pepperoni contains green pepper ;
The fraction of the whole pizza that contains both pepperoni and green pepper;
The fraction with pepperoni = 3/4
Fraction of whole with green pepper and pepperoni: 2/3 of 3/4
simplifying the above equation, we get
= 2/3 × 3/4
= (2 × 3) / (3 × 4)
= 6/12 = 1/2
Therefore, the fraction of whole pizza has both pepperoni and green peppers exists 1/2.

It will be valued less than £1000 after x = -0.8260748 years.
Based on the given conditions, formulate:
6700 × (1 - 28%) = 1000
Calculate the sum or difference:
6700 ×0.72ˣ = 1000
Reduce the greatest common factor on both sides of the equation:

which expression can be used to find the surface area of the following rectangular prism A 15+10+6B 15+15+15+6 C 6+6+10+10+15+15D 6+10
Answer:
C. 6 + 6 + 10 + 10 + 15 + 15
Explanation:
The surface area of a rectangular prism can be calculated as:
Surface Area = lw + lw + wh + wh + lh +lh
Where l is the length, w is the width, and h is the height.
So, replacing l by 3, w by 2, and h by 5, we get:
Surface Area = 3(2) + 3(2) + 2(5) + 2(5) + 3(5) + 3(5)
Surface Area = 6 + 6 + 10 + 10 + 15 + 15
Therefore, the expression that can be used to find the surface area is:
Surface Area = 6 + 6 + 10 + 10 + 15 + 15

A population of values has a normal distribution with μ=62.9 and σ=25.8. You intend to draw a random sample of size n=22.
In a population of values having a normal distribution with (μ = 62.9) and (σ = 25.8), and we intend to draw a random sample of size (n = 22),
(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3) is 0.2476
(ii) The probability that a sample of size (n = 22) is randomly selected with a mean less than 45.3 [P(M < 45.3)] is (0.0007)
As per the question statement, a population of values has a normal distribution with (μ = 62.9) and (σ = 25.8) and we intend to draw a random sample of size (n = 22).
We are required to calculate:
(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3)
(ii) The probability that a sample of size (n = 242) is randomly selected less than 45.3 [P(M < 45.3)].
Let us assume that, a random variable "X" follows normal distribution with mean (μ = 62.9), standard deviation (σ = 25.8) and a sample size of (n = 22).
(i) The probability that a single randomly selected value is less than 45.3 [P(X < 45.3) is,
P (X < 45.3) = P[{(X - μ)/σ} < {(45.3 - 62.9)/25.8}]
= [P{Z < (-0.6822)}]
=0.247556247343...[Using Excel Function "NORMSDIST (-0.6822)]
≈ 0.2476
(ii) The probability that a sample of size (n = 22) is randomly selected with a mean less than 45.3 [P(M < 45.3)] is,
P(M < 45.3) = P[{(M - μ)/(σ/√n)} < {(45.3 - 62.9)/25.8/√22)}]
= P[{(M - μ)/(σ/√n)} < {(45.3 - 62.9)/5.5006}]

Answer
a) The plotted graph is shown in the Explanation below.
b) a = 12, b = 2
Explanation
n = a(b^m)
Taking the logarithm of both sides
log n = log [a(b^m)]
log n = log a + log (b^m)
log n = log a + m log b
So, to first plot the graph, we know we need to rewrite this equation to match the equation of a straight line. Equation of a straight line is
y = mx + b
where
y = y-coordinate of a point on the line.
m = slope of the line.
x = x-coordinate of the point on the line whose y-coordinate is y.
b = y-intercept of the line.
log n = (log b) m + log a
y = mx + b
y-axis = log n
slope = log b
x-axis = m
intercept = log a
So, we need to plot log n (on the y-axis) against m (on the x-axis)
m | n | log n
1 | 24 | 1.38
2 | 48 | 1.68
3 | 96 | 1.98
4 | 192 | 2.28
5 | 384 | 2.58
The values for log n are then plotted against the corresponding value of m
The image is presented below.
From the graph, we can easily see that
Intercept = 1
To obtain the slope, for a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as
Using the two farthest points,
(x₁, y₁) and (x₂, y₂) = (1, 1.38) and (5, 2.58)
[tex]\begin{gathered} Slope=m=\frac{Change\text{ in y}}{Change\text{ in x}}=\frac{y_2-y_1}{x_2-x_1} \\ \text{Slope = }\frac{2.58-1.38}{5-1}=\frac{1.2}{4}=0.3 \end{gathered}[/tex]b) Intercept = log a = 1.08
a = log⁻¹ (1.08) = 12
Slope = log b = 0.3
b = log⁻¹ (0.3) = 1.995 = 2
n = 12 (2^m)
We can test this by putting values of m in the expression looking to get n
when m = 1,
n = 12 (2^1)
n = 12 (2) = 24
when m = 5
n = 12 (2^5)
n = 12 (32) = 384
So, our model works!!!
Hope this Helps!!!

The divisor (12) goes into the bottom number (35), 2 time(s). Therefore put 2 on top:
0 1 2
1 2 ⟌ 1 5 5
- 0
1 5
- 1 2
3 5
Step 11:
Multiply the divisor by the result in the previous step (12 x 2 = 24) and write the answer at the bottom:
0 1 2
1 2 ⟌ 1 5 5
- 0
1 5
- 1 2
3 5
2 4
Step 12:
Subtract the result in the previous step from the number written above it. (35 - 24 = 11) and write the answer at the bottom.
0 1 2
1 2 ⟌ 1 5 5
- 0
1 5
- 1 2
3 5
- 2 4
1 1
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 155 divided by 12 calculated using Long Division is:12

Find the height of the tree if the tree's shadow is 13 feet and the stick person's height is 5.2 feet, and the stick person's shadow is 4 feet.?
Answer: 16.9 feet.
Step-by-step explanation:
The person's shadow is 1.3 times its shadow, which was found by dividing 5.2 by 4. Once we have the proportion, we can multiply the tree's shadow by 1.3 and get 16.9 feet.
How do yu solve -8w times -w
The result of the expression -8w times -w is [tex]8w^{2}[/tex]
The expression is -8w times -w
Expressions is the mathematical statements that have a minimum of two terms containing numbers or variables, connected by an operator in between. The operator maybe addition, subtraction, division or multiplication.
Here the expression is -8w times -w
Here -8w times -w means, we have to multiply the -8w by -w
Therefore the expression is
-8w × -w
We know when we multiply the a negative number by negative number the result will be positive number
-8w × -w = [tex]8w^{2}[/tex]
Hence, the result of the expression -8w times -w is [tex]8w^{2}[/tex]

Given
jenny mixed 4kg of mixed nuts containing 16% of peanuts with 12kg of mixed nuts containing 40% of peanuts .
Find
Percent in the new mixture of peanuts
Explanation
we are given 4kg of mixed nuts containing 16% of peanuts
Amount of quantity =
[tex]\frac{percentage}{100}\times totalamount[/tex]so,
[tex]\frac{16}{100}\times4=0.64kg[/tex]and also 12kg of mixed nuts containing 40% of peanuts .
so,
[tex]\frac{40}{100}\times12=4.8kg[/tex]so,total weight
[tex]0.64+4.80=5.44kg[/tex]let total mass pf mixture containing x % peanuts.
so,
[tex]\begin{gathered} \frac{5.44}{16}=\frac{x}{100} \\ 34=x \end{gathered}[/tex]Final Answer
Percent in the new mixture of peanuts = 34%
