6 less than the product of 7 and this number is 85.
6 less than (the product of (7 and this number)) is 85.
6 less than (the product of 7 and x) = 85
6 less than (7 * x) = 85
(7 * x) - 6 = 85
Now you solve! Make sure that whatever you do to one side you also do to the other:
7x - 6 = 85
7x - 6 + 6 = 85 + 6
7x = 91
7x /7 = 91 /7
x = 13
Hope this helps! :)
Answer:
95.44%
Step-by-step explanation:
Mean (m) = 48
Standard deviation (sd) = 9
n = 12
Zscore = (x - m) /sd
X = 30
Zscore = (30 - 48) / 9
Zscore = - 2
X = 66
Zscore = (66 - 48) / 9
Zscore = 2
percentage of daily phone calls numbering between 30 and 66 = P(z < 2) - p(z < - 2)
P(z < 2) = 0.9772
P(z < - 2) = 0.0228
Hence,
0.9772 - 0.0228 = 0.9544
0.9544 * 100% = 95.44
Answer:
-6
Step-by-step explanation:
because the roots are the x values of where the function crosses the x axis
so thats at -2 and 3
and product is multiplication
so -2×3= -6
Question is not stated clearly
First, find the distance AB by the formula:
If A(0,-7) and B(8,8), then
Dilating polygon ABCD by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′, you increase the distance AB twice, A'B'=2AB. Thus, A'B'=2·17=34 units.
Answer: AB=17 units, A'B'=34 units.
