0.02

Step-by-step explanation:

High schools A :

Percentage of participants in on the school athletic team = 20%

Pa = 20% = 0.2

High school B:

Percentage of participants in on the school athletic team = 18%

Pa = 18% = 0.18

The mean of sampling distributon is :

Pa - Pb

0.2 - 0.18

Hence, Mean of sampling distribution is 0.02

Answer:

Step-by-step explanation:

first take x-y=0 and multiply it by -5 you will then get this

-5x+5y=0

5x-2y=6

add those together

3y=6

divide by 3

y=2

now plug 2 in for y

x-2=0

add 2 to both sides

x=2

Answer:

x = 63

Step-by-step explanation:

Simplifying

x + -18 = 45

Reorder the terms:

-18 + x = 45

Solving

-18 + x = 45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '18' to each side of the equation.

-18 + 18 + x = 45 + 18

Combine like terms: -18 + 18 = 0

0 + x = 45 + 18

x = 45 + 18

Combine like terms: 45 + 18 = 63

x = 63

Simplifying

x = 63

Step-by-step explanation:

if we multiply the first equation by neg 2, the 4x's cancel out.

The method that should be selected is

2. Multiply the first equation by -2 and add the second equation.

In the elimination method, we can either add or subtract the equations to get an equation in one variable. At the time When the coefficients of one variable are opposites, so we can add the equations to eliminate a variable and when the coefficients of one variable are equal we can subtract the equations to eliminate a variable.

Step-by-step explanation:

you can't find the exact angle with the given info so option 1 is automatic out, m<1 is also clearly an obtuse angle so it will be larger then 90° so option 2 is out, and like I said before m<1 has to be larger then 90° so its not option 3 leaving only option 4

15(2x+2)=10(3x+4)  Distribute.

30x+30=30x+40     Subtract 30x from both sides.

-30x       -30x

30=40

30 does not equal 40, so there is no solution.

Answer in interval notation is  (-3, 1)

This is the same as saying -3 < x < 1

=====================================================

Explanation:

Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.

These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.

Given:

w varies jointly as x and y.

w=10 when x=2 and y=1.

To find:

The value of w when x=4 and y=2​.

Solution:

w varies jointly as x and y.

[tex]w\propto xy[/tex]

[tex]w=kxy[/tex]              ...(i)

Where, k is the constant of proportionality.

w=10 when x=2 and y=1.

[tex]10=k(2)(1)[/tex]

[tex]10=2k[/tex]

[tex]\dfrac{10}{2}=k[/tex]

[tex]5=k[/tex]

The value of k is 5.

Putting k=5 in (i), we get

[tex]w=5xy[/tex]

To find the value of w when x=4 and y=2​. Put x=4 and y=2.

[tex]w=5(4)(2)[/tex]

[tex]w=40[/tex]

Therefore, the value of w is 40 when x=4 and y=2​.

Step-by-step explanation:

A trapezoid is a quadrilateral (has four sides and four angles) with a pair of opposite parallel sides. The pair of opposite parallel side is known as the base.

An isosceles trapezoid is a trapezoid with equal legs. The diagonals are also equal and both the upper and lower base angles are congruent.

From the question:

KV = IE = 2x + 6 (diagonals of a trapezoid are congruent)

From line segment addition postulate:

KV = KN + NV

substituting:

2x + 6 = 10 + x

2x + 6 - x = 10

x + 6 = 10

x = 10 - 6

x = 4

KV = 2x + 6

substituting x = 4:

KV = 2(4) + 6

KV = 14

Answer: get the 2 perfums in the size 50ml

Step-by-step explanation:

80ml is 55 pound

50 ml is 45 pound

2nd is half of 45 pound which is 22.5

the 2 perfum in the size 50 ml with the special price is: 45 + 22.5 = 67.5 now per ml is 0.675 pound per ml i found the price per pound by dividing the ml by the price

for the 80ml the price per ml is 0.6875

Answer: The required scale factor[tex]=\dfrac43[/tex]

Step-by-step explanation:

Formula : [tex]\text{Scale factor }=\dfrac{\text{Side in image}}{\text{Corresponding side in pre-image}}[/tex]

Here, ED = 3 units  in Δ DEF which corresponding to SR = 4 units in ΔRST

Now,

Scale factor for the given transformation = [tex]\dfrac{SR}{ED}[/tex]

[tex]=\dfrac{4}{3}[/tex]

hence, the required scale factor[tex]=\dfrac43[/tex]

Answer:

(-2, 3)

Step-by-step explanation:

The solution to a system of equations is the value (or values) of x and y that satisfy both equations. we can find the value of x by setting the right sides of each of our equations equal to each other and solving:

[tex]4x+11=-2x-1\\6x=-12\\x=-2[/tex]

From here, we can simply substitute -2 for x in either of the equations to calculate y. I'll choose the bottom one:

[tex]y=-2(-2)-1\\y=4-1\\y=3[/tex]

So our solution is (-2, 3).
