1. Kelly bounces a basketball 30 times in 50 seconds. At that rate,
approximately how many times will Kelly bounce the ball in 150
seconds?
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.

The expected value of a random variable X is 140 and the standard deviation is 14. The expected value of the random variable Y
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 :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
Find the slope Y=5x+12
Answer: The slope = 5.
Step-by-step explanation:
The equation of a line in the slope -intercept form is given by :-
[tex]y=mx+c[/tex]
,where m= slope , c= y-intercept.
The slope of a line represents the rate of change of y with respect to x.
Given: Equation of line : Y= 5x+12
Here Slope (m)=5
Hence, the slope = 5.
Hi!

Where:

[tex]\diamondsuit~~\large\boldsymbol{b- > y-intercept}[/tex]
Notes:
Please remember that the slope is the coefficient of x (the number that comes just before x; in 5x, the coefficient of x is 5), and the y-intercept is added to or subtracted from the slope.Therefore,

The number of cars in 25 families is shown in the table. Calculate the mean number of cars in a family.
No of cars Frequency
1 5
2 10
3 7
4 2
5 1
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
If a regression analysis shows an R factor of 0.15, it is safe to assume a perfect positive relationship between cost and volume. a strong negative relationship between cost and volume. a strong positive relationship between cost and volume. a very weak relationship between cost and volume.
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:
-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.

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.

Solve the system of linear equations by substitution 4x − 2y = 16, 2x + y = 5
Answer: x = 3.25, y = -1.5
Step-by-step explanation:
y = -2x + 5
4x - 2(-2x + 5) = 16
4x + 4x - 10 = 16
8x = 26
x = 3.25
2(3.25) + y = 5
y = -1.5

Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election. They surveyed 650 randomly selected community college students and found that 55% of them plan to vote.
Which of the following are the appropriate null and alternative hypotheses for this research question?
A)
0: =0.50
: ≠0.50
B)
0: =0.50
: >0.50
C)
0: =0.55
: ≠0.55
D)
0: =0.55
: >0.55
Answer is:
B
Answer:
[tex]H_{0} = 0.5[/tex]
[tex]H_{a} > 0.5[/tex]
Option b
Step-by-step explanation:
Researchers conducted a study to determine whether the majority of community college students plan to vote in the next presidential election.
The null hypothesis is always an equalityu related to the expected, or tested value. In this question, the tested value is half of the students, a proportion of 0.5, that is: [tex]H_{0} = 0.5[/tex]
The alternate hypothesis is related to the test we are taking. In this question, we are testing if the majority of the students plan to vote, that is, if the proportion of the students that plan to vote is higher than 0.5. So [tex]H_{a} > 0.5[/tex]
So the correct answer is given by option B.
