Answer:
Hence from the given value male and female.
From this confidence intervals do not overlap so adult females have higher rate than adult males.
Step-by-step explanation:
Taking mean for female = 3025 / 40 = 75.6
taking mean for male = 2666/40 =66.65
Construction of hypothesis:
For 90 % confidence interval for adult female :
72.0 bpm <μ<75.2 bpm
For 90 % confidence interval of adult females:
66.65 bpm<μ<70.6 bpm
From this confidence intervals do not overlap so adult females have higher rate than adult males.
Answer:
79.38 mile per hour
$6.76
Step-by-step explanation:
It was easy, just divide and multiply
Y > 2x - 3
3y - x ≤ 6
↓
y = 2x - 3
3y - x = 6
3(2x - 3) - x = 6
3(2x) - 3(3) - x = 6
6x - 9 - x = 6
6x - x - 9 = 6
5x - 9 = 6
<u> + 9 + 9</u>
<u>5x</u> = <u>15</u>
5 5
x = 3
y = 2x - 3
y = 2(3) - 3
y = 6 - 3
y = 3
(x, y) = (3, 3)

93
On a number line: Start at 0. Count forward until you reach 36. Once you've reached 36, Mark it. Then you go forward 57, from the mark you made at 36. You should end up on 93 on the number line.
