Answer:
99.7% of the students have grade point averages that are between 1.42 and 3.7
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 of 2.56 and standard deviation of 0.38.
Using the empirical rule, what percentage of the students have grade point averages that are between 1.42 and 3.7?
1.42 = 2.56 - 3*0.38
3.7 = 2.56 + 3*0.38
So both these scores are within 3 standard deviations of the mean, which means that 99.7% of the students have grade point averages that are between 1.42 and 3.7

f(x) = X/x-1 and g(x) = 1+1/x find (g. f) (x) and (f. G) (x)
Answer:
Given f(x)=(1−x)21 and g(x)=ln(x)
gof(x)
=g(f(x))
=ln(1−x)1/2
=21ln(1−x)
∴ For the composite function to be defined 1−x>0
x<1
∴ Domain is (−∞,1)

Answer: D
Step-by-step explanation:
10.Suppose that you have bought 3 large glass-fronted cabinets. You have three workers, A, B and C, to help you with transporting the cabinets from the furniture store to your home, and you want them to finish it in (at most) one trip each. From past experience, it is known that the probability that A breaks something in a given trip is 10%, the probability that B breaks something in a given trip is 15%, and the probability that C breaks something in a given trip is 20%. The events that A, B, or C breaks something in a given trip are independent of each other. You come up with three strategies: (a) A transports all the furniture, (b) A transports two cabinets and B transports one cabinet, or (c)
Answer:
Step-by-step explanation:
To find the expected no of broken cabinets for each strategy.
If A transport all the furniture
Suppose X₁ = number of furniture A broken
X₁ follows a binomial with n = 3, p = 0.10
E(X₁) = np
E(X₁) = 3 × 0.1
E(X₁) = 0.3
If A transport two (2) cabinets & B transport one (1) cabinet
expected no. of the broken cabinet by A out of 2 is
= 2 × 0.1
= 0.2
Suppose X₂ denotes the no of broken furniture by B
E(X₂) = np
where n= 1 and p = 0.15
E(X₂) = np
E(X₂) = 1 × 0.15
E(X₂) = 0.15
Thus. the expected number of broken cabinets = 0.2 + 0.15 = 0.35

What is the slope of the line shown below? • (3,9) O A. -3 ch (1,3) O B. -6 O c. 6 O D. 3 # SUBM
The slope of the line with the coordinate points (-3, 9) and (1, 3) is -1.5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y₂-y₁)/(x₂-x₁).
The given coordinate points are (-3, 9) and (1, 3).
Substitute, (x₁, y₁)=(-3, 9) and (x₂, y₂)=(1, 3) in the slope formula, we get
Slope = (3-9)/(1-(-3))
= -6/4
= -3/2
= -1.5
Therefore, the slope is -1.5.

Answer: The formula to determine the multiplier is M = 1 / (1 - MPC). Once the multiplier is determined, the multiplier effect, or amount of money needed to be injected into an economy, can also be determined. This amount is calculated by dividing the total amount of spending needed by the multiplier.

The function is continuous if you can draw its graph without lifting your pencil. In this case, that means each of the piecewise function definitions must have the same value at x=3.
x^2 +2 = 6x +k . . . . . must be true at x=3
3^2 +2 = 6(3) +k . . . . substitute 3 for x

Write 31/24 as a decimal rounded to the nearest tenth
Answer:
1.3
Step-by-step explanation:
just divide 31 by 24
This will give you the decimal: 1.291666667
Since the number 2 is right of the decimal point, it is in the tenths place.
Therefore, since the number next to the 2 is 9, you would round the 2 up and get 1.3 as your answer.
