5. Suppose a set of math test scores is normally distributed with a mean of 100 (you do not need to know the standard deviation to answer this question, but you may find it helpful to plug in a standard deviation of your choice). If you randomly select a sample of scores from this distribution, which of the following probabilities is higher? Explain your answer.

a. The probability of the sample mean falling between 100 and 105 with a sample of 25 scores.
b. The probability of the sample mean falling between 100 and 105 with a sample of 36 scores.

Answer:

You can use 48 and 24

Step-by-step explanation:

You can figure out 48 by simply multiplying 6 times 8. You can figure out the 24 by noticing that 24 is divisible by both 6 and 8. 6 x 4 =24, and 8 x 3=24. I hope this helps!

Answer:

[tex]h=4[/tex]

Step-by-step explanation:

We know that the vertex(lowest point) of [tex]|x-h|[/tex] is [tex](h, 0)[/tex].

By inspection, we can see that the vertex of the graph is [tex](4, 0)[/tex].

So, the lowest point of [tex]F(x)=|x-h|[/tex] is [tex](4, 0)[/tex], which means [tex]\boxed{h=4}[/tex]

Answer:

Step-by-step explanation:

0=|x-h|

x=h,

but y=0 when x=4

so h=4

Coordinates of G will be : (3, 7)

Slope of a line is a number that describes both the direction and the steepness of the line.

Since , slope of line = (y2-y1)/ (x2-x1)      equation 1

According to question :

given :  slope =4

F is located at (2,3), which implies x1 = 2 and y1 = 3

now , substituting the value in equation 1 , we get

4 = y2 - 3 / x2 - 2

4 * x2 - y2 = 5                                 equation 2

Using above options , let us do hit and trial method in order to find answer.

Firstly let us take option A) 6,4

putting value of x2=6 in equation 2 and see if y2 comes 4 or not?

4*(6) - y2 =5

y2 = 24-5

y2 = 19 which is not equal to 4 , hence this is incorrect option.

secondly , let us take option B) 3,7

similarly we get ,

4* 3 - y2 =5

12 -5 = y2

y2=7 hence this is the correct option

B) 3,7 is the answer

Answer:

There is no direct question on here so I'll just assume you're asking how many rides she can get on???

Step-by-step explanation:

6 x 1 = 6

6 x 2 = 12

6 x 3 = 18

6 x 4 = 24

6 x 5 = 30

6 x 6 = 36

6 x 7 = 42

So she can get on about 6 rides (once again, if thats what ur trying to ask..)

Step-by-step explanation:

A = (3, 6)

B = (6, 9)

C = (9, 3)

first scaled down (dilated) by the factor of 1/3 in the direction of the origin = point (0, 0).

then moved left by 2 units and down by 3 units.

the dilation about the origin simply multiplies each coordinate by the scale factor.

Ad = (3×1/3, 6×1/3) = (1, 2)

Bd = (6×1/3, 9×1/3) = (2, 3)

Cd = (9×1/3, 3×1/3) = (3, 1)

to move 2 units to the left means to subtract 2 from the x coordinates.

to move 3 units down means to subtract 3 from the y coordinates.

A' = (1-2, 2-3) = (-1, -1)

B' = (2-2, 3-3) = (0, 0)

C' = (3-2, 1-3) = (1, -2)

therefore, B is the right answer option.

Answer:

  k = 2

Step-by-step explanation:

The slope formula gives the slope between two points:

  m = (y2 -y1)/(x2 -x1)

  -2 = (-2 -0)/(3 -k)

Multiplying by (3 -k) gives ...

  -2(3 -k) = -2

  3 -k = 1

  k = 3 -1 = 2

The value of k is 2.

Answer:

9:30

Step-by-step explanation:

9:30 = 3:10

If we put a ratio into a fraction for better visual representation, we will see that 3:10 turns in 3/10. If we multiply both the numerator and denominator by 3, we will get 9/30. You can divide 3 from both sides of 9/30 and it will go back to 3/10.

tl:dr Multiply both sides of a ratio to get the equivalent ratio.

Step-by-step explanation:

The hypotenuse is always the longest side.

Explanation:

For any triangle, the longest side is always opposite the largest angle.

Step-by-step explanation:

this line goes through the points (0, -3) and (4, 0).

so, the y-axis intercept is at y = -3.

therefore, the equation has to end with "- 3".

the slope (the factor of x in the equation) is the y/x ratio of the changes of y and of x when going from one point to the other :

x changes by 4 positive units (from 0 to 4), and y changes by 3 positive units (from -3 to 0).

so, the slope is 3/4.

and so, the equation is

y = (3/4)x - 3

Answer:

Step-by-step explanation:

two points on the line are (-2,0) and (0,4)

slope=(y2-y1)/(x2-x1)=(4-0)/(0-(-2))=4/2=2

eq. of line is y-0=2(x-(-2))

y=2(x+2)

y=2x+4

Answer:

5:6

Step-by-step explanation:

when adding the two probabilities together, they should equal 6:6. So, 5:6 is the odds of winning.

The probability is the ratio of the favorable event to the total number of events. Then the probability that Bucksnot will win the race is 5/6.

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.

The odds against the horse Bucksnot winning the race are 1:6.

Then the probability that Bucksnot will win the race will be

[tex]\rm P = 1 - \dfrac{1}{6}\\\\P = \dfrac{5}{6}[/tex]
