Answer:
L = the slanted height of the pyramid
Step-by-step explanation:
The surface area of a pyramid is given by :
[tex]SA=\dfrac{1}{2}PL+B[/tex]
Where
P is perimeter of base of pyramid
L is the slant height of the pyramid
B is the area of base.
So, the correct option is (c) "the slanted height of the pyramid".
The table below shows the values for the function
y = f(x).
Complete the table for the
function
y = f(1/5x).
Given:
The table of values of function [tex]y=f(x)[/tex] is given.
To find:
The table of values of function [tex]y=f(\dfrac{1}{5}x)[/tex].
Solution:
The horizontal stretch is defined as:
[tex]g(x)=f(ax), 0<a<1[/tex]
Here, f(x) is horizontally stretched by factor a to get g(x).
The given function is:
[tex]y=f(\dfrac{1}{5}x)[/tex]
It means the function [tex]y=f(x)[/tex] is horizontally stretched by factor [tex]\dfrac{1}{5}[/tex] to get [tex]y=f(\dfrac{1}{5}x)[/tex].
So, we need to multiply the given x-values by 5 to get the required table of values.
Therefore, the required table of values is:
x y

In a completely randomized experimental design involving three assembly methods, 30 employees were randomly selected and 10 were assigned to each of the three methods. The time required to complete the task was recorded. The following information is provided: MSTR = 45.89 and MSE = 6.27. What is the critical value of F if we want to determine whether the means of the three populations are equal at the 5% level of significance?
Answer:
The answer is "3.35".
Step-by-step explanation:
Treatment independence degree
[tex]= 3 - 1 \\\\= 2[/tex]
Grade of error independence
[tex]= 30 - 3 \\\\= 27[/tex]
[tex]\alpha = 0.05[/tex]

In how many ways can you answer 15 true/false questions
Answer:
32768
Step-by-step explanation:
Each question has 2 options.
On a true/false test with one question, there are 2¹, or 2 possible answers
On a test with 2 questions, there are 2², or 4 possible answers.
On a test with 3 questions, there are 2³, or 8 possible answers.
So, 2¹⁵ = 32768 possible ways.

what is the area of a square with its side length of s cm
Answer:
Step-by-step explanation:
Answer:
The area is s².
Step-by-step explanation:
The area of a square is the length times the width. Because it's a square, the length and width are the same, so instead of multiplying the length and width, we can take the length of one side and square it. You said the length is "s", which I assume is a variable, so the area will equal s ⋅ s, or s².

When Victoria goes bowling, her scores are normally distributed with a mean of 130 and a standard deviation of 11. What is the probability that the next game Victoria bowls, her score will be between 123 and 130, to the nearest thousandth?
Answer:
0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 130 and a standard deviation of 11.
This means that [tex]\mu = 130, \sigma = 11[/tex]
What is the probability that the next game Victoria bowls, her score will be between 123 and 130?
This is the p-value of Z when X = 130 subtracted by the p-value of Z when X = 123. So
X = 130
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{130 - 130}{11}[/tex]
[tex]Z = 0[/tex]
[tex]Z = 0[/tex] has a p-value of 0.5
X = 123
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{123 - 130}{11}[/tex]
[tex]Z = -0.64[/tex]
[tex]Z = -0.64[/tex] has a p-value of 0.2611
0.5 - 0.261 = 0.239
0.239 = 23.9% probability that the next game Victoria bowls, her score will be between 123 and 130

Step-by-step explanation:
This is a right angle triangleSo apply Pythagoras Theron[tex] \\ \rm \mapsto \: {h}^{2} = {p}^{2} + {b }^{2} \\ \\ \rm \mapsto \: h = \sqrt{ {p}^{2} + {b}^{2} } \\ \\ \rm \mapsto \: h = \sqrt{ {50}^{2} + {180}^{2} } \\ \\ \rm \mapsto \: h = \sqrt{2500 + 32400} \\ \\ \rm \mapsto \: h = \sqrt{34900} \\ \\ \rm \mapsto \: h = 186.8[/tex]
Answer:
187
Step-by-step explanation:
[tex]50^{2}[/tex] + [tex]180^{2}[/tex] = 2500 + 32400
2500 + 32400 = 34900
[tex]\sqrt{34900}[/tex] = 186.81541692269406

The slope of the line below is -2. Write the equation of the line in point-slope
form, using the coordinates of the labeled point. Do not use parenthesis on
the y side.
Answer:
y=-2x-3
Step-by-step explanation:
Since the slope is -2, we can make an equation : y=-2x+b
Now plug in the point given to find b.
1=-2(-2)+b
1=4+b
b=-3
so, the equation is y=-2x-3

The quadratic regression equation that fits these data is -1.107 X² +3.736 X +10.643 .
What is Quadratic Regression ?A quadratic regression is the process of finding the equation of the parabola that best fits a set of data. As a result, we get an equation of the form:
y=ax2+bx+c where a≠0 .
The best way to find this equation manually is by using the least squares method.
That is, we need to find the values of a ,b, and c such that the squared vertical distance between each point (xi,yi) and the quadratic curve y=ax2+bx+c is minimal.
After solving we get the values of a , b, and c and thus we form the equation
-1.107 X² +3.736 X +10.643

f(x) = 3x2 – 2x - 9
g(x) = 3x2 + 2x2 - 4x - 9
Find (f - g)(x).
9514 1404 393
Answer:
(f -g)(x) = -3x^3 +x^2 +2x
Step-by-step explanation:
We assume the expression for g(x) has a typo, and the first term should be 3x^3.
(f -g)(x) = f(x) -g(x) = (3x^2 -2x -9) -(3x^3 +2x^2 -4x -9)
= 3x^2 -2x -9 -3x^3 -2x^2 +4x +9
= -3x^3 +(3 -2)x^2 +(-2+4)x +(-9+9)
(f -g)(x) = -3x^3 +x^2 +2x

Jill took a photograph of a plane taking off. Her mother is an air-traffic controller and was able to estimate the measurements shown. How far is the plane above the ground? Round to the nearest yard?
56 yards
75 yards
40 yards
60 yards
Answer:
75 yards .
Step-by-step explanation:
Let 90 yards be h ,50 yards be b and remaining side be p
h^2 = p^2 + b^2
90×90=p^2+50×50
90×90-50×50=p^2
root 5600=p
p=74.833
