Answer:
$1.935
Step-by-step explanation:
As the store is offering a 15% discount, you have to calculate the 15% of the price of the game app to find the amount of the discount:
Price of the game app= 12.90
12.90*15%=1.935
According to this, the answer is that the amount of the discount if you buy the game app during the sale is $1.935 and you would have to pay: 12.90-1.935= $10.965.
Answer:
B. 97
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How many students should be sampled to be within 1 drink of the population mean with 95% probability?
This is n when 
We know from preliminary studies that the standard deviation is around 5, so 
We round up, so the correct answer is:
B. 97
Answer: {−4,7} is y=x2−3x−28 y = x 2 - 3 x - 28 .
Step-by-step explanation: so all ways do y and x first
You need to get x alone. start by solving the left side. 2(x) = 2x - 1=10
add one to each side 2x=11 then divide 11/2 to get what x=
