X is a normally Distributed random variable with a standard deviation of 4.00. Find the mean of X when 64.8% of the area lies to the left of 8.52.
Answer:
7
Step-by-step explanation:
σ = 4 ; μ =?
8.52 to the left of X
.
P(X < 8.52) = 64.8%
P(X < 8.52) = 0.648
Using the Z relation :
(x - μ) / σ
P(Z < (8.52 - μ) / 4)) = 0.648
The Z value of 0.648 of the lower tail is equal to 0.38 (Z probability calculator)
Z = 8.52 - μ / 4
0.38 = 8.52 - μ / 4
0.38 * 4 = 8.52 - μ
1.52 = 8.52 - μ
μ = 8.52 - 1.52
μ = 7

[tex]\mathbb{ANSWER:}[/tex]
We can write the equation of variation as [tex]\sf y = \frac{k}{x^2}[/tex] since [tex]\sf y \propto \frac{1}{x^2}[/tex]. The independent variable is y while the dependent variable is x^2. The variable k denotes the constant of proportionality.

At the Fisher farm, the weights of zucchini squash are Normally distributed. Which standardized weight represents the top 10% of the zucchinis?
Find the z-table here.
–1.64
–1.28
1.28
1.64
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.
How to get the z scores?If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.
[tex]Z = \dfrac{X - \mu}{\sigma}[/tex]
Here, X is sample, is μ mean and is σ standard deviation.
At the Fisher farm, the weights of zucchini squash are Normally distributed.
For the normal distribution let the value of mean is 0 and standard deviation 1. Thus,
[tex]Z = \dfrac{X - \mu}{\sigma}\\Z = \dfrac{X - 0}{1}\\Z=X[/tex]
For the top 10% of the zucchinis, the value of α is 0.9. From the table for this value the z score is,
[tex]Z=X=1.28[/tex]
Thus, the standardized weight which represents the top 10% of the zucchinis from the z-table for the fisher farm is 1.28.

Cameron and some friends are going to the movies. At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75. How much would it cost if they bought 3 bags of popcorn and 6 drinks? How much would it cost if they bought pp bags of popcorn and dd drinks?
Answer:
Total cost= $39
Step-by-step explanation:
Giving the following information:
At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.
First, we will establish the total cost formula:
Total cost= 5.5p + 3.75d
p= number of bags of popcorn
d= number of drinks
Now, for 3 bags and 6 drinks:
Total cost= 5.5*3 + 3.75*6
Total cost= $39

Find the volume of the cylinder. Either enter an exact answer in terms of T or use 3.14 for T. 6 for height 8 for width
nvm I got it it was 384
Answer:
The volume of the cylinder is equal to 1205.76 cubic units.
Step-by-step explanation:
Given that,
Height of the cylinder, h = 6
Radius of the cylinder, r = 8
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\V=3.14\times 8^2\times 6\\\\V=1205.76\ units^3[/tex]
So, the volume of the cylinder is equal to 1205.76 cubic units.

Step-by-step explanation:
Given
Difference between [tex]\frac{3}{5}[/tex] Raman's present age and his age 4 years ago is 0
Suppose Raman's present age is [tex]x[/tex]
So, we can write
[tex]\Rightarrow \dfrac{3x}{5}-(x-4)=0\\\Rightarrow \dfrac{3x-5x}{5}+4=0\\\Rightarrow \dfrac{-2x}{5}+4=0\\\Rightarrow x=\dfrac{20}{2}=10[/tex]

Step-by-step explanation:
1A.
The sum of the measure of the interior angle of a convex octagon is given as
S = (n-2)180°................. Equation 1
Where n = 8 sides
S = (8-2)180°
S = 6×180°
S = 1080°
1B.
The sum of the angle of a convex pentagon is given as
S = (5-2)180°
S = 3×180°
S = 540°
From the diagram,
2x+142+2x+(3x+14)+(3x+14) = 540
10x+170 = 540
10x = 540-170
10x = 370
x = 37°
Hence,
∠H = ∠K = 2(37) = 74°,
∠M = ∠L= (3×37)+14 = 111+14 = 125°
There are 144 square inches in 1 square foot. How many square inches are in 2.5 square feet?
Answer:
360 square inches
Step-by-step explanation:
There are 360 square inches in 2.5 square feet.
To find out how many square inches are in 2.5 square feet, we need to multiply the number of square feet by the conversion factor.
Given that there are 144 square inches in 1 square foot, we can set up a proportion to solve for the number of square inches in 2.5 square feet:
1 square foot = 144 square inches
2.5 square feet = x square inches
Setting up the proportion:
1 square foot / 144 square inches = 2.5 square feet / x square inches
Cross-multiplying the proportions:
(1 square foot) x square inches = 144 square inches (2.5 square feet)
Simplifying the equation:
x square inches = 144 square inches (2.5 square feet)
Multiplying the values:
x square inches = 360 square inches
Therefore, there are 360 square inches in 2.5 square feet.
