Answer:
b, y = 9x + 7
Step-by-step explanation:
Since the graph y = 9x + 10 is being "translated" 3 units down, that means the slope of the equation remains the same, but the y intercept is being moved 3 units down.
y = mx + b
y-intercept = b = 10
10 - 3 = 7
the answer is b, y = 9x + 7
Answer:
0.3763
Step-by-step explanation:
Given :
- Students graduated = 71%
- Male students = 49%
- Female Students = 100% - 49% = 51%
- Female students out of graduated students = 53%
Prob (Female & Graduate) = Proportion of female of students who graduate who graduate
= 53% of 71% = 0.53 x 0.71 = 0.3763
I believe -3(2n)2 is equal to -6n(2)
Answer:
A normal distribution or z-test is used to construct a confidence interval.
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= $3120
Sample size, n = 40
Population standard deviation, σ = $677
The distribution of earnings of college is a normal distribution.
Conditions:
- Since we are given the population standard deviation and the the sample size is also greater than 30.
Conclusion:
Thus, we use a normal distribution or z-test to construct a confidence interval.
