The sample size needs to be 96.
First we find the z-score for this confidence interval:
Convert 95% to a decimal: 95/100 = 0.95
Subtract from 1: 1 - 0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1 = 0.025 = 0.975
Using a z-table (http://www.z-table.com) we look up this value in the chart; the z-score that goes with this value is 1.96.
Now we use the formula
Answer:
THERE Fake Toes!!!!
Step-by-step explanation:
Never criticize someone until you have walked a mile in their shoes.
That way, when you criticize them, you’ll be a mile away, and you’ll have their shoes.

Step-by-step explanation:
To see if the Triangle is right use Pythagorean theorem which is A^2+B^2=C^2
A and B are to 10 and 24 because the longest side, the hypotenuse is C
10^2+24^2=676
26^2=676
Therefore the triangle is right
Answer:
3x + 2 ≤ 53
Step-by-step explanation:
"2 more than" means that there will be a + 2 in the equation. "3 times a number" means that 3 is multiplied by an unknown number which can be represented by a variable such as x. "At most" means less than or equal to, since the number cannot be greater than.
So generally, you might want to write the equation as 2 + 3x ≤ 53, but 2 + 3x is not in y = mx + b form. Basically, you need to write it as 3x + 2 ≤ 53 because that's how math works.
A positive × A negative = Negative
A positive × A positive = Positve
A negative × A negative = Positive
