Answer:
13 miles.
Step-by-step explanation:
These distances form a right angled triangle with legs 4+1 = 5 and (7+5) = 12 miles and the distance between A and B is the hypotenuse.
So the distance AB^2 = 5^2 + 12^2 = 169
AB = sqrt 169 = 13 miles.
Answer:
x=.83
Step-by-step explanation:
What you do is you have to get x by itself.
You will have to divide 250 on both sides to get x by itself.
x=.83 is your answer.
Firstly, <span>(1 + 2x)^(2) = 4x² + 4x +1
so the anti derivative of f(x) = </span>4x² + 4x +1 is F(x) = integral (4x² + 4x +1) dx=
(4/3)x^3 +(4/3)x² + x +C
Answer:
6 Hours
Step-by-step explanation:
No.of leaflets---no.of people---work hours
1000 ————. 4. - — — — — — — 5
1500 — — — —5 — — — — — ,— —?
If work increase, no.of people needed more
So, the required ratio is 1500/1000
If work men increase, no of hours decrease
So, the required ratio is 4/5
(1500/1000)× (4/5)×5 = 6
No.of hours required to distribute 1500 leaflets by 5 people = 6 hours
Answer:
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
Step-by-step explanation:
The following information is missing in the question:
Mean, μ = 170
Standard Deviation, σ = 30
Using the given information, we may solve the question as:
We are given that the distribution of distribution of cholesterol levels in teenage boys is a bell shaped distribution that is a normal distribution.
Formula:
a) P( cholesterol level greater than 225)
P(x > 225)
Calculation the value from standard normal z table, we have,
0.033 is the probability that a teenage boy has a cholesterol level greater than 225.
