Answer: option B
Step-by-step explanation: at alpha level of 5% for a two tailed test, the critical value is +1.96 and -1.96
At alpha level of 1% for a two tailed test, the critical value is +2.576 and -2.576
Relating z = 2.77 with these critical values, we can see that at 5% level of significance, z = 2.77 is greater than +1.96 which falls in the rejection region.
Also at 1% level of significance, we can see that z = 2.77 is greater than 2.576 which also falls in the rejection region.
Answer:
No.
Step-by-step explanation:
Because standard form is ax+by=c.
Answer:
d. tan (35) =
Step-by-step explanation:
<u>You must memorize the definitions of all the trig functions.</u>
Tan of an angle = opposite side/adjacent side
In your case, the opposite side of the 35° angle is x and the adjacent side of the 35° angle is 10
So, tan 35 = x/10
The system of inequalities that represents the number of copies that Julissa can print to meet her goal is given by:
- .
- .
<h3>What is a system of inequalities?</h3>
A system of equations is when two or more variables are related, and inequalities are built to find the values of each variable.
The variables are given as follows:
- Variable x: Number of color copies.
- Variable y: Number of gray scale copies.
She needs to print no fewer than 8 copies, hence:
.
It takes 4 minutes to print a color copy and 2 minutes to print a grayscale copy. She has at most 25 minutes, hence:
.

Answer:
You could set up this equation:
100 x = 1
x = 1 / 100
Therefore, x = .01
