Answer:
B) 2 + 4x = 5 - 3 - 3x
Step-by-step explanation:
By simplifying JUST the right side and re-arranging them
2 + 4x = 5 - 3(x + 1),
2 + 4x = 5 - 3x -3,
2 + 4x = 5 -3 - 3x
Answer:
+ 16
Step-by-step explanation:
x² - 8x = - 10
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 4)x + (- 4) = - 10 + (- 4)²
x² - 8x + 16 = - 10 + 16
thus 16 is added to both sides to complete the square
<u>Answer:</u>
1/9 > -4
because -4 is a negative no less than 0. whereas 1/9 is a positive no greater than 0.
So negative no can't be greater than positive no.
Answer:
B. (6, 10)
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 = 8
Standard deviation = 1
Give an interval that is likely to contain about 95% of the sampled cashiers' hourly wages.
By the Empirical Rule, 95% of the sampled cashiers' hourly wages will be within 2 standard deviations of the mean, so from 2 standard deviations below the mean to two standard deviations above the mean
Two standard deviations below the mean:
8 - 2*1 = 6
Two standard deviations above the mean
8 + 2*1 = 10
So the correct answer is:
B. (6, 10)
5 times 2 times 8 would equal 80
Answer :80
