Priya was busy studying this week and ran 7 fewer miles than last week. She ran 9 times as far as Elena ran this week. Elena only had time to run 4 miles this week.
How many miles did Priya run last week
Elena writes the equation 1/9(x﹣7) = 4 to describe the situation. She solves the equation by multiplying each side by 9 and then adding 7 to each side. How does her solution compare to the way you found Priya’s miles?
Answer:
1) The number of miles Priya ran last week was 43 miles
2) The way Elena found Priya's miles is faster compared to the way it was found here
Step-by-step explanation:
1) The number of miles Priya ran this week = The number of miles Priya ran last week - 7
The number of miles Priya ran this week = 9 × The number of miles Elena ran this week
The number of miles Elena ran this week = 4 miles
Therefore;
Let the number of miles Priya ran last week = x miles
The number of miles Priya ran this week = (x - 7) miles
Therefore, we have
(x - 7) = 9 × The number of miles Elena ran this week = 9 × 4 miles = 36 miles
x = (36 + 7) miles = 43 miles
The number of miles Priya ran last week = x miles = 43 miles
The number of miles Priya ran last week = 43 miles
2) From (x - 7) = 9 × The number of miles Elena ran this week = 9 × 4 miles = 36 miles, we have;
(x - 7) = 9 × 4
1/9(x - 7) = 4
Therefore, multiplying by 9, we have;
9 × 1/9(x - 7) = 9 × 4
(x - 7) = 9 × 4 = 36
x - 7 + 7 = 36 + 7
x = 43 miles
Therefore, the way Elena found Priya's miles is faster compared to the way it is found here

8. if u is uniform on [0,1], find the density function of √u .
The density function of √u, where u is uniformly distributed on [0,1], is f(v) = 2√v for 0 ≤ v ≤ 1.
To find the density function of √u, where u is uniformly distributed on the interval [0,1], we can use the transformation method.
Let's denote the random variable √u as v = √u. We want to find the probability density function (PDF) of v.
First, we find the cumulative distribution function (CDF) of v:
F(v) = P(v ≤ x) = P(√u ≤ x) = P(u ≤ x²) = x², for 0 ≤ x ≤ 1.
Next, we differentiate the CDF to obtain the PDF of v:
[tex]\begin{equation}f(v) = \frac{d}{dv} F(v) = \frac{d}{dv} (x^2) = 2x, \quad 0 \leq x \leq 1[/tex]
However, we need to express the PDF in terms of v, not x. Since v = √u, we can substitute x = √v into the PDF:
f(v) = 2√v, for 0 ≤ v ≤ 1.
Therefore, the density function of √u is f(v) = 2√v, for 0 ≤ v ≤ 1.

Jordan has a garden that is enclosed by a rectangular fence. The perimeter of the garden is 84 feet. The length of one side of fencing is 8 yards. What is the area of Jordan’s garden
Answer:
432 square feet
Step-by-step explanation:
We know perimeter of rectangle is 2(length + width)
we already know that length is 8 yards
and perimeter is 84 feet
we need to find width first
then
we find area of garden by using formula
area of rectangle = length * width
first we need to convert yards into feet as perimeter is in yards
1 yard = 3 feet
8 yards = 3*8 feet = 24 feet
now we plug value of length and perimeter in formula
perimeter = 2(length + width)
84 = 2(24 + width)
84/2 = 24 + width
=> 42 = 24 + width
=> width = 42 - 24 = 18
Thus, width of garden is 18 feet
now
area of Jordan's garden = length * width = 24* 18 feet square
area of Jordan's garden = 432 square feet

P(X = 0) = 0.335 Probability = 0.335.The given formula for probability distribution is:P(X) = (n! / x! (n - x)!) * πx * (1 - π)n - xwhere, P = Probability X = Random variable, n = Total number of trialsπ = Probability of success. Let us consider the given probabilities:(a) For n - 5 and π = 0.16, what is P(X:0)?When n = 5 and x = 0, then n - x = 5.
Therefore,
P(X = 0) = (5! / 0!

(n - x)!) * πx * (1 - π)n - xWhere,P is the probability,X is the random variable,n is the total number of trials, andπ is the probability of success. The first probability is to calculate the probability for n - 5 and π = 0.16, what is P(X:0)?The value of x is zero, and n - x is 5. The formula is applied to get the probability, and it is rounded off to four decimal places as needed.

population has a mean of 200 and a standard deviation of 70 . Suppose a sample of size 125 is selected and
x
ˉ
is used to estimate μ. Use z-table. What is the probability that the sample mean will be within +1−7 of the population mean (to 4 decimals)? (Round z value in intermediate calculations to z ) decimal places.) b. What is the probablity that the sample mean will be within +/−17 of the population mean (to 4 decimals)? (Round z value in intermediate calculations to 2 ) decimal places.)
a. The probability corresponding to a z-score of -9.7143 is also approximately 0.0000.
b. The probability that the sample mean will be within +/−17 of the population mean is 0.0000.
To find the probability that the sample mean will be within a certain range of the population mean, we need to calculate the z-scores for the given range and then use the z-table to find the corresponding probabilities.
For the first question, we want to find the probability that the sample mean will be within +1−7 of the population mean. To calculate this, we need to convert the range into z-scores. The range +1−7 can be rewritten as -7 to +1.
The formula for calculating the z-score is:
z = (x - μ) / (σ / √n)
In this case, the population mean (μ) is 200, the standard deviation (σ) is 70, and the sample size (n) is 125.
For -7:
z = (-7 - 200) / (70 / √125) = -7.2857
For +1:
z = (1 - 200) / (70 / √125) = -9.7143
Next, we look up the corresponding probabilities in the z-table. From the z-table, the probability corresponding to a z-score of -7.2857 is approximately 0.0000, and the probability corresponding to a z-score of -9.7143 is also approximately 0.0000.
Therefore, the probability that the sample mean will be within +1−7 of the population mean is 0.0000.
For the second question, we want to find the probability that the sample mean will be within +/−17 of the population mean. Using the same approach, we calculate the z-scores:
For -17:
z = (-17 - 200) / (70 / √125) = -17.8571
For +17:
z = (17 - 200) / (70 / √125) = -20.2857
Looking up the probabilities in the z-table, we find that the probability corresponding to a z-score of -17.8571 is approximately 0.0000, and the probability corresponding to a z-score of -20.2857 is also approximately 0.0000.
Therefore, the probability that the sample mean will be within +/−17 of the population mean is 0.0000.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
x=3
Step-by-step explanation:
the 3 angles of a triangle equal 180
you add 105 and 46, which equals 151
you subtract 151 from 180 to see what the missing angle is (29)
you would make 6x+11 equal to 29
-subtract 11 from 29= 18
6x/6, 18/6
the answer is 3
hope this helps! :)
The value of x in the given triangle is 3°.
A triangle is an object with three sides, three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
Given that the sum of angles in a triangle is equal to 180 degrees. The sum of angles in the given triangle would also be equal to 180. This can be represented with this equation:
105° + 46° + (6x + 11)° = 180°
Combine similar terms
162° + 6x° = 180°
6x° = 180° - 162°
6x = 18°
Divide both sides of the equation by 6
x = 3°

144=-12(x+5) solve for the following
Answer:
-17 = x
Step-by-step explanation:
The solution to the equation is x = -17.
To solve the equation 144 = -12(x + 5) for 'x,' follow these steps:
Step 1: Divide both sides by -12 to isolate the term with 'x':
144 / -12 = -12(x + 5) / -12
Step 2: Simplify the left side and evaluate the right side:
-12 = x + 5
Step 3: Move the constant term to one side by subtracting 5 from both sides:
-12 - 5 = x + 5 - 5
Step 4: Simplify the left side and calculate 'x':
x = -17
The solution to the equation is x = -17. To verify, substitute 'x' with -17 in the original equation:
144 = -12(-17 + 5)
144 = -12(-12)
144 = 144
Since both sides are equal, the value of x = -17 is correct. Therefore, the solution to the equation is x = -17.
