Answer:

Mean = 11.8

Step-by-step explanation:

Given the following data;

Total number of cars (n) = 5

Number of cars (x) = 1, 2, 3, 4, 5

Frequency (F) = 5, 10, 7, 2, 1

F(x) = (1*5) + (2*10) + (3*7) + (4*2) + (5*1)

F(x) = 5 + 20 + 21 + 8 + 5

F(x) = 59

To find the mean;

Mean = F(x)/n

Mean = 59/5

Mean = 11.8

Complete question :

The expected value of a random variable X is 140 and the standard deviation is 14. The standard deviation of the random variable Y=3X-10 is:

Answer:

42

Step-by-step explanation:

Standard deviation of Y = 3X - 10

The variance of Y

Var(Y) = Var(3X - 10)

Var(Y) = Var(3X) - Var(10)

10 is a constant :

Var(10) = 0

Hence,

Var(Y) = Var(3x)

SD(Y) = Var(Y) = Var(3X)

SD(Y) = SD(3X)

SD(Y) = 3SD(X)

SD(X) = 14

SD(Y) = 3 * 14

SD(Y) = 42

Answer:

-8 < x, the answer is B

Step-by-step explanation:

Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.

Reminder:

<--------------- Negative side/Lower -----------------------> Positive side/Greater

Answer: sooooo....... the answer is n=20

Step-by-step explanation: did you really needed the answer for this?

Answer:

n = -30

Step-by-step explanation:

5 = 10 + n/6

-5 = n/6

n = -30

Answer:

a) clusters: none, gaps: 99, and 100, peaks: 101, outliers: none.

b) center of distribution:

median: 101, mean: 99.9090.

(a)

The outliers are the values that are far from the middle.

In this case, the outliers are 97, 98, 98, 98.

A cluster occurs when the data occurs within a small interval.

In this case, there's a cluster between 100 and 102.

According to the dot plot, there's a gap from 98 to 101.

At last, the peak is at 101, which is the value with the highest frequency.

(b)

The given data set doesn't form a normal distribution because there's no data in the middle of the data set, instead, there's a gap. Additionally, the spread or range of the data set is 5, where the majority of the data is not in the middle which mean the dispersion of the data is important.

Answer:

84 candies in a 4.2 ounce bag

Step-by-step explanation:

30/1.5 = 20 candies per ounce

20(4.2) = 84 candies in a 4.2 ounce bag

Answer:

answer for this is 12 and for b is 5

Answer:

12/20 I think since you would multiply 5 by 4 so you would multiply 3 by 4. Hope this helps!☺️

Answer:

kelly would of hit the ball 90 times in 150 seconds

Step-by-step explanation:

you take 30 and divide it by 50 and you get 0.6.

then you take 0.6 and times it be 150

Answer:

90 times

Step-by-step explanation:

The equation set-up for if she bounces a basketball 30 times in 50 seconds is 30x=50. This means that she bounced the ball every 1 2/3 second. According to this, our next equation set-up would be 1 2/3x=150. If we divide 150 by 1 2/3, we get 90. This means that Kelly bounced the basketball 90 times in 150 seconds.

Answer:

a very weak relationship between cost and volume

Step-by-step explanation:

The R factor is used to access the strength of the relationship between a dependent and independent variable. The R factor ranges between - 1 and 1. With negative values depicting a negative linear relationship and positive values meaning a positive relationship. The closer the R factor is to - 1 or + 1, the greater the strength, a value of 0 means, no correlation exists.

Hence, a R factor of 0.15 depicts a positive but very weak relationship between cost and volume as the R value is close to 0.

Answer:

1) 3

2) 5/4

3) 5/9

Step-by-step explanation:

1) Change the sign to multiplication and change 1/4 into it's reciprocal which is 4/1. Multiply 3/4 · 4/1 to get 12/4.

Simplifies to 3

2) Change the sign to multiplication and find the reciprocal of 1/2 which is 2/1. Multiply 5/8 · 2/1 to get 10/8

Simplifies to 5/4

3) First, change the sign to multiplication then find the reciprocal of 3/4 which is 4/3. Multiply 5/12 · 4/3 to get 20/36.

Simplifies to 5/9

Answer :the 1st and 3rd are true

Step-by-step explanation:

you do the math how their set up so just right those and you can get your answer that way. (if your adding a positive and negative your basically subtracting so just write in the order their in; if you subtracting a negative from a positive it equals a positive; if your subtracting a negative from a negative or the answer is positive; if your subtracting a positive from a negative its negative) i hope this helps if u have any more questions just message me and i  will be happy to help you anytime!!! <3

Step-by-step explanation:

Answer:

m<R = 22.62°

Step-by-step explanation:

Reference angle = R

Opposite = 5 cm

Hypotenuse = 13 cm

Apply the trigonometric function SOH:

Sin R = Opp/Hyp

[tex] Sin (R) = \frac{5}{13} [/tex]

[tex] R = sin^{-1}(\frac{5}{13}) [/tex]

R = 22.6198649°

m<R = 22.62° (nearest hundredth)

Answer:

The size of the sample is 840.

The probability that the first three letters of the four-letter code are vowels is=\frac{1}{35}=

35

1

Step-by-step explanation:

Th total number of letters given to form code of 4 letters = 7

Since, the order of the letters in the code matters, which means there is no repetition.

The total number of ways to form the code size =7*6*5*4=8407∗6∗5∗4=840

Therefore, The size of the sample is 840.

Since, there are 3 vowels and rest of 4 letters are consonant.

The number of ways to form code such that the first three letters of the four-letter code are vowels =3\times2\times1\times4=243×2×1×4=24

The probability that the first three letters of the four-letter code are vowels is

=\frac{24}{840}=\frac{1}{35}

840

Step-by-step explanation:

< AEB + < BEC = 180° {BEING LINEAR PAIR }

26° + < BEC = 180°

< BEC = 180° - 26°

< BEC = 154°

ARC BC = < BEC ( relation between arc and central angle)

Arc BC = 154°
