Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 640 randomly s

tatyana61 [14]

Answer:

Given:

Sample size, n = 640

Since result showed that 99.2% of them would erase all of their personal information online if they could, we have:

P' = 99.2% = 0.992

Let's take p = 50%

Our null and alternative hypothesis will be :

H0 : u = 0.5

H1 : u > 0.5

In this case we are to check for the test statistic.

$\frac{P' - p}{\sqrt{p(1-p)/n}}$

$= \frac{0.992 - 50}{\sqrt{50(1-50)/640}}$

= 24.9

Test statistic, Z = 24.893

In conclusion, the results are significantly high, which suggets there is suffcient evidence to support the claim that most adults would erase all of their personal information online.

Line AB is Perpendicular to line BC. A=(-3,2) and C=(2,7). Which of the following could be the coordinates of B? Select all that

Llana [10]

Answer:

The answer would be Choice F; (-3,7)

Step-by-step explanation:

Plot the two guaranteed given points
A, (-3,2) and C, (2,7)
Find the point where the x and y would share and then form a right angle. This is called being Perpendicular.
So, take the x of A, and the y of C and you have the coordinates of B.
