Answer:
-7.90
Step-by-step explanation:
Let's write the null hypothesis (H0) and alternative hypothesis (Ha) from the claim statement
P = population proportion of adults who would erase all of their personal information online if they could
H_{0}:P=0.5
H1 P< 0.5
Let's write the given information:
n = sample size = 480
sample proportion = 
formula of z test statistic for one sample proportion test is as follows:
plug the above values in the above formula we get
So that the test statistic value is -7.90 (Rounded up to two decimal places)
Answer:
I believe that the answer is 95 meters.
Explanation:
Okay, so to solve this question, you must know the formula to solve for the area of a rectangle/square.
<em>Area of a rectangle/square - </em><em>l x w</em>
<em />
In this question, you can see the the width (72 m) and the area (6840 m²) is already given. What you can do in this situation is to use the opposite operator (division) to solve for the length of the rectangular field.
<em>6840 ÷ 72 = </em><em>95</em>
You can always double check to see if the number is correct.
<em>A = l x w</em>
<em>= 72 m x 95 m</em>
<em>= </em><em>6840 m</em>²
Really hope this helped. :)
7/y....the coefficient of y is 1
any time u have a variable by itself, whether it is x or y or any letter, the coefficient is gonna be 1
Triangles ABC and ADE are similar triangles. That means the sides are all scaled by the same factor.
To go from side BC to side DE, you multiply by 1.25. That means 1.25 is your scale factor. Now apply that factor to the bottom side to get your answer.
Side AB is 6. That means side AD is 6 x 1.25 = 7.5. That means x = 7.5 - 6 = 1.5
Answer:
the answer is A {126,168,189}
