Answer:
y = 2
Step-by-step explanation:
6y - 5 = 7
~Add 5 to both sides
6y = 12
~Divide 6 to both sides
y = 2
Best of Luck!
Answer:
Step-by-step explanation:
B + G = 300 (million)
G = B - 38 (million)
B + B - 38 = 300
2B - 38 = 300
2B = 300 + 38
2B = 338
B = 338/2
B = 169 million <=== Beyonce
G = B - 38
G = 169 - 38
G = 131 million <==== Guns N Roses
Answer:
C. 45 and 141 seconds
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 93 seconds
Standard deviation = 16 seconds
99.7% of running times are approximately between:
By the Empirical rule, within 3 standard deviations of the mean, so between 3 standard deviations below the mean and 3 standard deviations above the mean
3 stnadard deviations below the mean
93 - 3*16 = 45 seconds
3 standard deviations above the mean
93 + 3*16 = 141 seconds
The correct answer is:
C. 45 and 141 seconds
: $55
:
Cost first 3 lines: $11 per line
Cost per additional line: $5
We are interested in 5-line ad, we place 3 lines or less, then we have to pay $11 per line in the ad.
Cost 5-lines = number of lines x cost per line
x = 5 x 11
55
