Suppose that 20% of students at high school A and 18% of students at high school B participate on a school athletic team. Independent random samples of 30 students from each school are selected and asked if they participate on a school athletic team. Let ˆ p A represent the sample proportion of students at school A who participate on a school athletic team and ˆ p B represent the sample proportion of students at school B who participate on a school athletic team.
What is the value of n A p A ?
What is the value of n A ( 1 − p A ) ?
What is the value of n B p B ?
What is the value of n B ( 1 − p B ) ?
Is the shape of the sampling distribution approximately Normal?
____, these values _____ all at least 10.
Answer:
6 ; 24 ; 5.4 ; 24.6
Step-by-step explanation:
Given that:
Number of samples from each high school = 30
Proportion of students from high school A = 20%
Proportion of students from high school B = 18%
Number of sample A ; n(A) = 30
Proportion of sample A ; p(A) = 0.20
Number of sample B ; n(B) = 30
Proportion of sample B ; p(B) = 0.18
1.)
n(A).p(A) = 30 * 0.20 = 6
2.)
n(A). (1 - p(A))
30 * (1 - 0.20)
30 * 0.8 = 24
3.)
n(B).p(B) = 30 * 0.18 = 5.4
4.)
n(B). (1 - p(B))
30 * (1 - 0.18)
30 * 0.82
= 24.6
Shape of sampling distribution is not approximately normal ;
Both nApA and nBpB are < 10
What feature or features of the parabolic parent function f(x)=x^2 would change if f(x) was replaced with 2f(x-4)? Help please:)
Answer:
The y-intercept of the function and the vertex of the function would change. (III and IV) This answer doesn't seem to be in the answer list (but there is proof for the answers below), though.
Step-by-step explanation:
(Notice that [tex]2f(x-4) = 2(x-4)^2.[/tex])
The domain of the function won't change because quadratics can all take all numbers as their input (which, by definition, is the domain of a function).
The range of the function won't change either, because we have just moved the function with 4 to the right (by substituting [tex]x[/tex] with [tex]x-4[/tex]) and multiplied the graph with respect to the y-axis by 2. The range will stay as all non-negative real numbers.
The y-intercept of the function will change, because for [tex]f(x)=x^2[/tex] it is [tex]y=0[/tex], while for [tex]y=2(x-4)^2[/tex] substituting [tex]x=0[/tex] doesn't give [tex]y=0[/tex]. (Instead, it gives [tex]y=32[/tex].)
The vertex of the function will change, because we have moved the function with 4 to the right and multiplied the graph with respect to the y-axis by 2: the vertex will have at the very least moved to the right.
Tanya is n years old today. How old will she be in 5 years
Answer:
n+5
Step-by-step explanation:
Answer:
n + 5 or 5 + n
Step-by-step explanation:
add 5 to n, tanya's current age, to find how old she'll be in 5 years.
since the variable n is not defined, the answer cannot be simplified further than n + 5.
if n had been defined, you would be able to figure out her exact age after 5 years, which would be the fully simplified answer. for example, if n were to equal 10, then tanya would currently be 10 years old. by plugging in 10 for n in n + 5, you would figure out that in 5 years (aka 10 + 5) tanya would be 15.

Corresponding angles
Find the value of x
Answer:
x = 54
Step-by-step explanation:
These are corresponding angles assuming that both transversals are parallel. Since these angles are corresponding, they must be congruent which means that both measures are the same.
Now the basic algebra can be done to find x:
(x + 12)° = 66°
(x)° = (66 – 12)°
(x)° = (54)°
x = 54

help i’ll give extra points
Answer:
y = x - 1
Step-by-step explanation:
The formula for slope-intercept form is:
y = mx + b
m = slope
b = y-intercept
Slope is equal to rise over run...Let's take points (1,0) and (2,1) for example, see how if you add 1 to (1,0) it turns to (2,1)? This means the slope is 1.
The y-intercept is where x is equal to 0. Look at point (0,-1). X is zero here, and y is -1. This means that the y-intercept is -1.
The final equation would then be:
y = x - 1
(You typically don't write the 1 in front of the x if 1 is the slope)

ABCD ~ FECG
Y=
Please helpp
=========================================================
Explanation:
Notice how EC = 5 doubles to BC = 5+5 = 10
So the larger quadrilateral (ABCD) has side lengths that are exactly twice as long compared to the smaller quadrilateral's sides. We can say the scale factor is 2.
This must mean that side FG = 4 doubles to 4*2 = 8, which is the length of side AD. So that's how we get y = 8.
-----------------------------------
Extra info:
x = 12 because side EF = 6 doubles to this value. w = 120 because the corresponding angles of ABCD pair up with FECG, so we see that angle D = angle G = 120.z = 80 because we solve F+E+C+G = 360 to find that F = 80, which leads to angle A = 80 as well.Length of AD, y = 8
What are similar quadrilateral?Two quadrilaterals are similar if their corresponding angles are equal and also their corresponding sides must be proportional.
Given,
EC = 5
FG = 4
BE = 5
AD = y
ABCD ~ FECG,
then ratio of the corresponding sides will be equal.
BC/AD = EC/FG
(BE + EC)/AD = EC/FG
(5 + 5)/y = 5/4
10/y = 5/4
5y = 40
y = 40/5
y = 8.
Hence, 8 is value of y that is length of AD.

Find all solutions of each equation on the interval [0, 2pi)
(cos^3x)/(sinx )=cot x
Answer:
Step-by-step explanation:
(cos³x)/(sin x)=cot x
(cos³ x)/(sin x)=(cos x)/sin x
sin x≠0
x≠0,π,2π
cos³x-cos x=0
cos x(cos²x-1)=0
either cos x=0,x=π/2 ,3π/2
or
cos²x-1=0
2 cos²x=2
1+cos 2x=2
cos 2x=1=cos2nπ,n=0,1,2
2x=2nπ
x=nπ
x=0,π,2π

Think About the Process Van purchased a DVD player on sale. The original
selling price was $175.90. The sale price was $149.62. What is the first step in
finding the percent markdown? Find the percent markdown.
much appreciated if helped :(
Answer:
14.940306992% or 15%
Step-by-step explanation:
To solve for percent or price markdown, you first have to find the difference between the original selling price and the sale price.
$ 175.90 - $ 149.62 = $26.28
Then, find the percentage that $26.28 is of the original selling price. You are decreasing the original by this much to get to the sale price.
$26.28 / $175.90
= 0.14940306992
Finally, multiply by 100 and round up to reach a percentage.

A certain flagpole that is 286 feet tall cast a shadow 137 feet long. Find the angle of elevation of the sun.
Answer: The angle of elevation of the sun [tex]=64.40^{\circ}[/tex]
Step-by-step explanation:
According to the trigonometry,
In a right triangle,
[tex]tan A=\dfrac{Perpendicular}{Base}[/tex]
Let angle of elevation of the sun = x
From the given figure, Perpendicular = 286 feet
Base = 137 feet
[tex]\tan x =\dfrac{286}{137}\\\\ \tan x = 2.0876\\\\ x=\tan^{-1}(2.0876)\\\\ x=64.40^{\circ}[/tex]
The angle of elevation of the sun [tex]=64.40^{\circ}[/tex]
