When x = 2



Answer:
0.03
Step-by-step explanation:w
standard deviation = ( p(1-p) / n)1/2
p= sample proportion= 55%
n= sample size = 900
standard deviation = ( [55/100] [ 1- 55/100]) / 900)1/2
= (0.55*0.45 / 900)1/2
= 0.0165
margin of error = critical value*standard deviation
[ from graph critical value = 2]
margin of error = 2*0.0165=0.033
Answer:
-10
Step-by-step explanation:
-7+(-3)= -7-3
= -(7+3)
= -10
Side note: Do you not have a caculator?
Answer: First option
Step-by-step explanation:
You have the quadratic equation given in the problem:

To find an equivalent expression you cacn factorize. Find two numbers whose sum is -13 and whose product is -30.
These numbers would be -15 and 2.
Therfore, you obtain the following equivalent expression:

If you don't want to apply the method above, you can use the quadratic formula:

Where:

When you susbstitute values you obtain that:

Then you can rewrite the equation as 
The sales price is $15.2
Step-by-step explanation:
Given,
Discount = 80%
Original price = $76
Discount price = 80% of original price

Sale's price = Original price - Discount price

The sales price is $15.2
