Answer:
looks like D but im not sure
Step-by-step explanation:
Look at the slope in each equation. For the first one is 15, the second is 25, the third is 40, and the fourth is 45.
Answer:
Step-by-step explanation:
9.
Sum of angles in triangle:
90 + 3x + 11 + 25 = 180
Add like terms:
126 + 3x = 180
Subtract 126 on both sides:
3x = 54
Divide:
x = 18
11.
Supplementary angles:
45 + 3x = 180
Subtract 45:
3x = 135
Divide 3:
x = 45
Answer:
F (x) = {32x+4, 0 < x < 10
25x + 9, x _> 10
Step-by-step explanation:
The one I guessed was wrong and it said that the one I put up above is the correct answer :)
w - 9 < 4w
Subtract w from both sides.
-9 < 3w
Divide both sides by 3.
-3 < w
The value of w is greater than -3.
<h3>The correct answer is C. </h3>
Answer:
Sample size = n = 37
Now we are supposed to find that the mean number of calls per salesperson per week is more than 42?
Since n > 30 so we will use z test
Formula :
Substitute the values
Z value at 0.100 is 1.64
Since the calculated z value is greater than the defined z value
So, we accept the null hypothesis
Hence we conclude that the mean number of calls per salesperson per week is not more than 42
