Answer:

x=0.933333

Step-by-step explanation:

First you add 6 to both sides of the equation

15x - 6 + 6 = 8 +6

That gives you 15x = 14

Then you divide 15 on both sides of the equation

That gives you x = 14/15 = 0.93333

You would start by adding six on both sides, which cancels out the negative 6 and then makes the 8 a 14.

15x = 14

Then you would divide each side by 15 which cancels out the 15 on the left leaving you with x on the left and 14/15 on the right.

X = 14/15 < Fraction

Answer:

Option A) reject null hypothesis if z is greater than 1.645

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 250

p = 30% = 0.3

Alpha, α = 0.05

Number of women belonging to union , x = 75

First, we design the null and the alternate hypothesis  

H_{0}: p = 0.3\\H_A: p > 0.3

This is a one-tailed(right) test.

Rejection Region:

z_{critical} \text{ at 0.05 level of significance } = 1.645

So, the rejection region will be

z > 1.64

That is we will reject the null hypothesis if the calculated z-statistic is greater than 1.645

Option A) reject null hypothesis if z is greater than 1.645

You just look where the line crossed the y axis and that’s your y intercept and for the slope you look at where the line perfectly intersects the squares and then count rise to run to each dot

Answer:

Answer down below :)

Step-by-step explanation:

The volume of the rectangular prism is:

20 x 9 = 180cm^2

The volume of the triangular prism is

6 x 9 x 1/2 = 27cm^2

I'm sorry, that is all I can do, but the total volume would be 180 + 27 + the cylinder's volume. Have a nice day :)

Answer:

1,041,958.5, or 104,195 1/2

Step-by-step explanation:

All you have to do is 15787.25 times 66, because 15787.25 is the price for on acre, so 66 acres will be 15787.25 times 66. If you want to put it in fraction form, you can do 15787 1/4 times 66. I hoped you liked this answer!
