If it took eight men ten hours to build a wall, how many hours would it take four men to build it?

2 answers:

8 0

8 men= 10hours
Now,
4men= ? hours

Since there are lesser number of men, the amount of time needed will be greater.. Thus, you need to multiply the amount of hours by 2! If you are thinking why, look at the following steps
8/2=4 (men)
10 x 2= 20(time)

Thus the answer is 20

Hope this helped :))

Two hours bc if it takes 8 to do it in one hour and u split the number of men u have in half you double the work hours 8men=1hour of work 4men=2hours of work
Hope this helps have a nice day

Solve by completing the square. w2 − 8w − 39 = 0 Write your answers as integers, proper or improper fractions in simplest form,

adell [148]

Answer:

4+√55= 11.42

4-√55= -3.42

Step-by-step explanation:

w² − 8w − 39 = 0
w²- 2*4w + 16- 55=0
(w-4)²=55
w-4=√55 ⇒ w= 4+√55= 11.42
w-4=- √55 ⇒ w= 4-√55= -3.42

A sample of 40 observations is selected from one population with a population standard deviation of 5. The sample mean is 102. A

marin [14]

1) This is a Two tailed Test.

2) Decision rule is; If the p-value is greater than 4% fail to reject H₀.

3) P-value = 0.00968764 and so we reject H₀

<h3>How to state the decision rule in hypothesis testing?</h3>

We are given the hypothesis as;

Null Hypothesis; H₀: m₁ = m₂

Alternative Hypothesis; H₁: m₁ ≠ m₂

1) Since the alternative hypothesis has "not equal to sign", then it is a two tailed test.

2) Since we are told to use significance level as 0.04, then we can say that the decision rule is;

If the p-value is greater than 4% fail to reject H₀.

3) Using a 2-Sample Z-Test online TI calculator gives the test statistic as;

z = 2.5868

4) From z-score calculator, p-value equals 0.00968764. This is less than 0.04 and as such the decision regarding H₀ is to reject H₀.

5) P-value = 0.00968764

This trapezoid has been divided into two right triangles and a rectangle.

jok3333 [9.3K]

The area of the triangle on left is in²: 9

The area of the triangle on the right is in²: 9

The area of the rectangle is in²: 108

The area of the trapezoid is in²: 126

<h3>Area of Compound Shapes</h3>

This exercise requires your knowledge about the area of compound shapes. For solving this, you should:

Identify the basic shapes;
Calculate your individual areas;
Sum each area found.

For finding the area, the steps are presented below.

STEP 1 - Identify the basic shapes.

This trapezoid is composed of two triangles and one rectangle. Therefore, you should sum the area of these geometric figures.

STEP 2 - Find the area of the triangle.

Area of the triangle - $A_{triangle}=\frac{b*h}{2}$ . The figure shows:

b= length of the base= 2in

h=height=9 in

Then, $A_{triangle}=\frac{b*h}{2}=\frac{2*9}{2} =\frac{18}{2}=9 in^2$

Note that the triangles are equals, consequently, they present the same values for the area.

STEP 3 - Find the area of the rectangle.

Area of the rectangle- $A_{rectangle}={b*h}$ . The figure shows:

b= length of the base= 12 in

h=height= 9in

Then, $A_{rectangle}={b*h}=12*9=108 in^2$ .

STEP 4 - Find the area of the trapezoid.

$A_{trapezoid}=2*A_{triangle}+1*A_{rectangle}\\ \\ A_{trapezoid}=2*9+1*108\\ \\ A_{trapezoid}=18+108\\ \\ A_{trapezoid}=126in^2$
