In a study of exercise, a large group of male runners walk on a treadmill for six minutes. Their heart rates in beats per minute at the end vary from runner to runner according to the (104,12.5) distribution. The heart rates for male nonrunners after the same exercise have the (130,17) distribution.
(a) What percent of the runners have heart rates above 140?
Answers
Percentage for the runners with heart rate of above 140 is 50.199% probability.
How to calculate heart rate probability?To calculate percentage of runners heart rate;
Mean, μ = 104
Standard deviation, σ = 12.5
Probability = P(X > 140)
P(X > 140) = [tex]1 - P (\frac{X - μ}{σ} \leq \frac{140 - μ}{σ})[/tex]
P(X > 140) = [tex]1 - P (Z \leq \frac{140 - 104}{12.5})[/tex]
P(X > 140) = [tex]1 - P (Z \leq \ 2.88)[/tex]
For a Z score of 2.88, the cumulative from mean probability and percentile are:
The normal distribution for 2.88 = 0.49801
P(X > 140) = 1 - 0.49801
P(X > 140) = 0.50199
P(X > 140) = 0.50199 x 100
The percentage for the heart rate = 50.199%
The probability of of runners heart rate above 140 is a 50.199% chance.

A boat heading out to sea starts out at Point AA, at a horizontal distance of 1023 feet from a lighthouse/the shore. From that point, the boat’s crew measures the angle of elevation to the lighthouse’s beacon-light from that point to be 11^{\circ} ∘ . At some later time, the crew measures the angle of elevation from point BB to be 2^{\circ} ∘ . Find the distance from point AA to point BB. Round your answer to the nearest foot if necessary.
Answers
Answer:22bb square roots
Explanation:none
A boat heading out to sea starts out at Point AA, at a horizontal distance of 1023 feet from a lighthouse/the shore. The distance from point AA to point BB is -1114.01 feet.
What is the distance?Distance is a numerical or qualitative measurement of the distance between two objects or places.
The distance of point A from the lighthouse = 1023 feet
The angle of elevation from point A to the lighthouse = 11°
The angle of elevation from point B to the lighthouse = 2°
tanΘ = opposite side to angle / adjacent side to the angle
tan7° = height from sea to the lighthouse / 1023 feet
Height to the lighthouse = tan(11°) × 1023 feet
0.1944 x 1023 feet = 198.8712
For point B
tan3° = 198.8712 feet
Horizontal distance = 198.8712 / tan3°
tan3° = -2.1850
Horizontal distance = 198.8712 / -2.1850 = -91.0165
D = Horizontal distance from B to LH - Horizontal distance from A to LH
Distance from A to B
-91.0165 - 1023 feet = -1114.01
Therefore, the distance from point AA to point BB is -1114.01 feet.

An architect wants to use the riser-tread formula to design a stairway with a total rise of 9 feet, a riser height between 7 and 8 inches, and an odd number of steps. With the architect’s constraints, which of the following must be the tread depth, in inches, of the stairway? (1 foot = 12 inches)
A) 7.2
B) 9.5
C) 10.6
D) 15
Answers
Answer:
Option C
The answer is 10.6
Explanation:
Here,
Total rise = 9 feet
Now, 1 foot = 12 inch
So, 9 x 12 inches = 108 inches
A riser height between 7 and 8 inches,
i.e., 8 ≤ h ≤ 7
Total riser = xh ...(1)
where x is the number of steps and h is the riser's height.
From equation (1),
x = Total riser ÷ h
Total riser = 108
h = 8 ≤ h ≤ 7
Thus,
x = 108/8 ≤ h ≤ 108/7
x = 14 ≤ h ≤ 15 ....(2)
Since the number of steps (x) is an odd number,
So, x = 15 [from equation (2)] (.°. 14 is not an odd number)
Also, from equation (1),
h = total riser/x
h = 108/x = 108/15 = 7.2 [it's between 7 and 8]
from riser-tread formula,
2h + d = 25
d = 25 - 2h
d = 25 - 2(7.2)
d = 25 - 14.4
d = 10.6
Thus, The answer is 10.6
-TheUnknownScientist
Answer:
Explanation:
The riser-tread formula states riser (R)+ tread (T) = 17 inches minimum, or 18 inches maximum.
Given R is between 7 - 8 inches, T must be between 9 - 11 inches. So the only choices within this range are B) 9.5 and C) 10.6.
As the number of steps must be odd:
for R between 7 - 8 inches, the total rise of 9 feet i.e. 108 inches requires -
108/7 = 15.4 ~ 16 steps to
108/8 = 13.5 ~ 14 steps
15 steps is an odd number between 14 and 16.
With 15 steps, R = 108/15 = 7.2"
For choice B, R + T = 7.2 + 9.5 = 16.7" which is short of the riser-thread formula.
For choice C, R + T = 7.2 + 10.6 = 17.8" which satisfies the riser-thread formula and is the correct answer.
Edit: I missed the riser-thread formula in this question has been defined as 2h + d = 25. So the above calculation was done with a different definition of the formula but arrived at the same answer.
Given the simple linear regression model y=b0+b1xi+µ the drive the error variance
Answers
The error variance can be Illustrated as σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b0 + b1x))^2
How to illustrate the error variance?The simple linear regression model is of the form:
y = b₀ + b₁x + μ
y = the dependent variable
x = the independent variable
b₀ and b₁ = the parameters of the model, and μ is the error term.
The error term represents the difference between the observed value of the dependent variable and the value predicted by the model. In other words, it is the deviation of the observed y from the expected value of y, given the value of x.
The error variance, denoted by σ^2, is a measure of the spread of the error term. It is calculated as the average squared deviation of the error term from its mean value, which is zero:
σ^2 = E(μ^2) = Var(μ) = (1/n) * ∑(y - (b₀ + b₁x))^2

Answers
The birds are more likely to survive than the fish because the fish actually live in the lake and get resources from there. If the lake gets polluted, the water, oxygen, and food will get worse and the fish will slowly start to die. But the birds can just look for their resources somewhere else.
Answer:
You see birds can fly but fish cannot. Birds can breath outside of water but fish can't. So in this scenario birds have the advantage. Fish can't leave the water so they will be contaminated with the pollution. Birds can leave the water because they can fly to safety.

In this case where the question is asking or OR and the events are mutually exclusive (Mutually exclusive meaning you can't attain two or three different colors in one pick), the compound probability is the sum of the probability of each component event (Probability of Red OR Blue = P(Red) + P(Blue) = 7/29 + 8/29 = 15/29)
