Suppose that grade point averages of undergraduate students at one university have a bell-shaped distribution with a mean of 2.56 and a 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?
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

Please help I’m begging I’ll make you brainliest
Answer:
t < 7 (all values less than 7)
All of the values make the inequality true except the bottom row
since you cannot leave 't' as a negative, divide each side of the inequality by -1 (but remember to reverse the inequality symbol)

Find an equivalent fraction to 5/6 only.
Answers:
A) 2/4
B) 10/12
C) 11/6
D) 20/24
E) 50/60
Answer:
B D and E
Step-by-step explanation:
Remark
It's hard to know how to tackle this. I suppose the easiest way is to divide the numerator and denominator by a common factor.
2/4
The common factor is 2
Divide the 2 by 2 and the 4 by 2
2/2 = 1
4/2 = 2
The fraction reduces down the 1/2 which is not 5/6
10 / 12
The common factor is 2.
10/2 = 5
12/2 = 6
Looks like this is your answer. But is it the only one.
11/6
These two have no common factor. The answer is 11/6 which is not 5/6
20 / 24
The common factor of these two is 4
20/4 = 5
24/ 4 = 6
This is also = to 5/6
50 / 60
The common factor is 10
50/10 = 5
60/10 = 6
That's equal to 5/6 as well.

Answer:
∠S = 38°
Step-by-step explanation:
The sum of angles in a triangle is 180°, so you have ...
(x+17)° +(2x-2)° +(5x+5)° = 180°
8x +20 = 180 . . . . . divide by °, collect terms
8x = 160 . . . . subtract 20
x = 20 . . . . . . divide by 8
∠S = (2x -2)° = (2·20 -2)°
∠S = 38°
Given the function g(x) = 4x - 5, compare and contrast g(2) and g(-4). Choose the statement that is true
concerning these two values.
O a
The value of g(2) is larger than the value of g(-4).
Oь
Ос
The value of g(2) is smaller than the value of g(-4).
The value of g(2) is the same as the value of g(-4).
The values of g(2) and g(-4) cannot be compared.
Od
Answer:
The value of g(2) is larger than the value of g(-4)
Step-by-step explanation:
2 is a larger number than -4, so automatically, the value of g(2) would be larger.
amy borrowed money from the lending company at 6% interest if she paid an interest of php450.00 after 19months how much money did she borrow
Answer:
She borrowed php4737.00.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
6% interest:
This means that [tex]I = 0.06[/tex]
19 months:
An year has 12 months, so [tex]t = \frac{19}{12} = 1.5833[/tex]
She paid an interest of php 450. How much money did she borrow
This is P when [tex]E = 450[/tex]. So
[tex]E = P*I*t[/tex]
[tex]450 = P*0.06*1.5833[/tex]
[tex]P = \frac{450}{0.06*1.5833}[/tex]
[tex]P = 4737[/tex]
She borrowed php4737.00.

can someone please show steps for this? i tried using a calculator but there was no fog sign thing.
Answer:
(f о g)(0) = 24
Step-by-step explanation:
f(x) = -5x - 1
g(x) = x² - 5
When you see (f о g)(#), they want you to plug the function g(x) into the function f(x).
First find g(0).
g(0) = (0)² - 5
g(0) = 0 - 5
g(0) = -5
Now plug g(0) = -5 into f(x) by replacing all x's with -5.
(f о g)(0) = -5(-5) - 1
Multiply.
(f о g)(0) = 25 - 1
Subtract.
(f о g)(0) = 24

Answer:
88.2
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relation ...
Tan = Opposite/Adjacent
tan(10°) = x/500
x = 500·tan(10°)
x ≈ 88.2 . . . . units
_____
If you move the "500" dimension to the top of the figure, you see it is adjacent to the given angle, and the value x is opposite.

For each graph below, state whether it represents a function.
Step-by-step explanation:
1. Not a function There is no correlation plus there is two y values for the same x.
2.Not a function, There is two y values for the same x
3.Yes, you can draw a linear line through the points to represent the equation, also there is one x for one y.
4.Yes, this is a step function. It seems there are two y values for same x. but the shaded circle means to include it and the open circle means dont include it so it is a function.
5.No, this is a parabola but this function has two y values for the same x
6. Yes, this is a absolute value function and there is multiple x values for the same y so it IS a function
Graph 3,6,4 represents a function because the x’s do not repeat and it passes the vertical line test. Which means 1,2,5 is not a function because the x's do repeat and it does not pass the vertical line test

Answer:
x = 7.5
Step-by-step explanation:
Since the midsegment and the third segment of the triangle are parallel to each other, therefore,
[tex] \frac{8 + 10}{8} = \frac{6 + x}{6} [/tex]
[tex] \frac{18}{8} = \frac{6 + x}{6} [/tex]
[tex] \frac{9}{4} = \frac{6 + x}{6} [/tex]
Cross multiply
[tex] 9*6 = 4(6 + x) [/tex]
[tex] 54 = 24 + 4x [/tex]
Subtract 24 from each side
54 - 24 = 4x
30 = 4x
Divide both sides by 4
30/4 = x
7.5 = x
x = 7.5

a girl took nine test in different subjects and had average of 60%. if in her tenth test she obtained 85%, find her new average
Answer:
62.5%
Step-by-step explanation:
average = sum of scores / number of scores
60% = [sum of 9 tests] / 9
[new average] = [sum of 10 tests] / 10
= ([sum of 9 tests] + 85%) / 10
= ((9 * 60%) + 85%) / 10
= 62.5%
On the unit circle, which of the following angles has the terminal point coordinates ( -v2/2 , -v2/2)
Answer:
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) =
OP.Cosθ = 1×Cosθ =
Cosθ =
θ = , where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ = , where n = integer
Common value of θ will be, θ =
