Answer:

s=2

Step-by-step explanation:

We are given the equation:

26-4s=9s

and asked to solve. We want to find out what the unknown variable, s, is. Therefore, we must isolate s on one side of the equation.

First, let's get all the terms with s on one side of the equation. 4s is being subtracted from 26. The inverse of subtraction is addition. Add 4s to both sides of the equation.

26-4s+4s=9s+4s

26=9s+4s

26=13s

s is being multiplied by 13. The inverse of multiplication is division. Divide both sides of the equation by 13.

26/13=13s/13

26/13=s

2=s

s=2

Let's check our solution. Plug 2 in for s and solve.

26-4s=9s

26-4(2)=9(2)

26-8=18

18=18

This checks out, so we know our solution is correct.

The solution to the equation 26-4s=9s is s=2.

The function A(b) relates the area of a trapezoid with a given height of 10 and
Natali5045456 [20]

The function of the trapezoid area is:

A(x)=(B+b)*h/2

Where B and b are the bases and h is the height.

With the given data: h=10 B and b =7 and x (it may vary which one is bigger)

-----------

So that function becomes:

A(x)=(7+x)*10/2

A(x)=(7+x)*5

----------

So if you want the inverse function, you have to operate to find x:

A(x)/5=7+x

A(x)/5-7=x

----------

So the new function is:

x(A)=A/5-7

A university dean is interested in determining the proportion of students who receive some sort of financial aid. Rather than ex
Roman55 [17]

Answer:

 Standard error (S.E) =  0.048  ≅ 0.05

Step-by-step explanation:

<u>Explanation</u>:-

Given  sample size 'n'=76

Given the dean who randomly selects 76 students and finds that 58 out of 76 are receiving financial aid.

Sample proportion

                         p = \frac{x}{n} = \frac{58}{76} = 0.7631

The standard error is determined by

                     S.E = \sqrt{\frac{p(1-p)}{n} }

                     S.E = \sqrt{\frac{0.763(0.2369}{76} }

  Standard error is 0.048  ≅ 0.05

What is m∠BAC.<br><br> ............
gizmo_the_mogwai [7]

Answer:

37 degrees

Step-by-step explanation:

1. m∠CBA = 71+45 = 116 degrees

2. m∠CBA = m∠CDA because of the quadrilateral property of opposite sides.

3. m∠CBA + m∠CDA = 2*116 = 232.

4. Total angle measure of a quadrilateral is 360 degrees, so m∠BAD + m∠BCD = 360-232 = 128 degrees.

5. m∠BAD = m∠BCD = 128/2 = 64 degrees

6. m∠BAC = m∠BAD - m∠CAD = 64 - 27 = 37 degrees
