The following list gives the number of siblings for each of 11 students. 0, 8, 9, 6, 5, 7, 2, 4, 3, 1, 11 Find the modes of this data set. If there is more than one mode, write them separated by commas. If there is no mode, click on "No mode."
Answer:
[tex]0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11[/tex]
Step-by-step explanation:
Given
[tex]0, 8, 9, 6, 5, 7, 2, 4, 3, 1, 11[/tex]
Required
Determine the mode
Though, not necessary; it is a good practice to order the given data either in ascending or descending order.
In ascending order, the ordered data are:
[tex]0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11[/tex]
Mode implies that: the data that has the highest number of occurrence.
In the given data, each data has a frequency of 1.
Hence, the mode is:
[tex]0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11[/tex]

g When comparing the 90 percent prediction and confidence intervals for a given regression analysis Multiple Choice the prediction interval is narrower than the confidence interval. the prediction interval is wider than the confidence interval. there is no difference between the size of the prediction and confidence intervals. no generalization is possible about their comparative width.
Answer:
the prediction interval is wider than the confidence interval
Step-by-step explanation:
Given that the confidence intervals depicts how a researcher got its parameter of interest, for example, regression coefficient, and prediction intervals show the researcher where to find the subsequent sampled data.
Therefore, Prediction intervals must cater to the uncertainty in estimating the population mean, and the random variation of the individual values.
Hence, when comparing the 90 percent prediction and confidence intervals for given regression analysis, a prediction interval is invariably wider than a confidence interval.
This explains the fact that the prediction interval will not collapse to a single value as the sample size rises.

In a study investigating a link between walking and improved health, researchers reported that adults walked an average of minutes in the past month for the purpose of health or recreation. Specify the null and alternative hypotheses for testing whether the true average number of minutes in the past month that adults walked for the purpose of health or recreation is than minutes.
Complete question is;
In a study investigating a link between walking and improved health, researchers reported that adults walked an average of 873 minutes in the past month for the purpose of health or recreation.
Specify the null and alternative hypotheses for testing whether the true average number of minutes in the past month that adults walked for the purpose of health or recreation is lower than 873 minutes
Answer:
Null Hypothesis: H0: μ = 873
Alternative hypothesis: Ha: μ < 873
Step-by-step explanation:
From the study, the claim is that the true average number of minutes gotten from the population average in the past month that the adults had walked for the purpose of health or recreation is lower than the average of 873 minutes.
Now, the population study says it's equal to 873 minutes.
Thus, the hypotheses can be written as;
Null Hypothesis: H0: μ = 873
Alternative hypothesis: Ha: μ < 873

Step-by-step explanation:We can make points from the given figure as ,
1 point =(x1, y1)=(-2, -3)
2nd point =(x2, y2)= (0, -6)
3rd point = (x3, y3)=(2 , -9)
Now the equation of line is,
Y=m X+ c where m is slope and c is constantnow two point formula of slope is ,
m = y2-y1/x2-x1putting points in it we get
m=(-6-(-3))/(0-(-2)
m=-3/2 is slope
Now to find C putt the value of m and 3rd point in equation of line we get
y3=m(x3)+c
-9=(-3/2)(2) +c
C= -9+3
C=-6 is value of c
Now at last putt the value of C and m in equation of line we get the required equation ,
Y=(-3/2)X-6 Ans.........................
Select all ordered pairs that satisfy the function y=4x+3.
I suppose that you should have given some pairs to choose from.
Anyway, I can tell you how to do it. Given a pair [tex](a,b)[/tex], you have to substitute [tex]a[/tex] and [tex]b[/tex] to [tex]x[/tex] and [tex]y[/tex] respectively, and see if you get something true.
For example, the pair [tex](1,7)[/tex] satisfies the function, because the substitution yields
[tex]7=4\cdot 1+3[/tex]
which is true. On the other hand, the pair [tex](19,3)[/tex] doesn't satisfy the function, because
[tex]3=4\cdot 19+3[/tex]
is clearly false.
It costs Guido $0.20 per minute to forward voicemail messages as texts to his cell phone. He already spent $4 in forwarding messages this month. His mom has spent $2 forwarding messages. It costs her $0.40 per minute so she can call long distance. Guido’s mom said they have to spend the same amount. How many minutes can he talk?
Answer:
10 Minutes
Step-by-step explanation:
To talk the same amount of time he would have to spend $2. So $0.20 per minute would mean that for 5 minutes it is $1, so he can have 10 minutes
P partitions GR in ratio 2:4. GR is 36cm. How long is GP and PR?
Answer:
12 cm and 24 cm
Step-by-step explanation:
The line is divided in the ratio 2 : 4 = 2x : 4x ( x is a multiplier )
The sum is therefore
2x + 4x = 36
6x = 36 ( divide both sides by 6 )
x = 6
Thus
GP = 2x = 2 × 6 = 12 cm
PR = 4x = 4 × 6 = 24 cm

What is an equation for the parabola with focus (0, -12) and directrix y = 12
Given:
Focus of a parabola is (0, -12) and directrix is y = 12.
To find:
The equation of the parabola.
Solution:
General form of a parabola is
[tex](x-h)^2=4p(y-k)[/tex] ...(i)
where, (h,k) is vertex, (h,k+p) is focus and y=k-p is directrix.
Focus is (0, -12).
[tex](h,k+p)=(0,-12)[/tex]
[tex]h=0[/tex]
[tex]k+p=-12[/tex] ...(ii)
Directrix is y = 12.
[tex]k-p=12[/tex] ...(iii)
Adding (ii) and (iii), we get
[tex]2k=0[/tex]
[tex]k=0[/tex]
Putting k=0 in (ii), we get
[tex]0+p=-12[/tex]
[tex]p=-12[/tex]
Putting h=0, k=0 and p=-12 in (i).
[tex](x-0)^2=4(-12)(y-0)[/tex]
[tex]x^2=-48y[/tex]
[tex]-\dfrac{1}{48}x^2=y[/tex]
Therefore, the required equation of parabola is [tex]y=-\dfrac{1}{48}x^2[/tex].

Point D is on segment BC. Segment BC measures 8x units in length.
A line has points C, D, B. The length of line C D is 3 x + 8. The length of line D B is 4 x + 10.
What is the length of segment BC?
Answer:
144Step-by-step explanation:
If point D is on BC, then BD + DC = BC
Given
BC = 8x
CD = 3x + 8
BD = 4x + 10
Substitute and get x
8x = 3x+8 + 4x + 10
9X - 7X = 18
x = 18
Get BCBC = 8x
BC = 8(18)
BC = 144
Hence the length of segment BC is 144
Answer:
144

the average rate of change of the function f(x) on the interval -3≤x≤3 is -2.5. If (-3)=14 then which of the following is the value of f(3)?
The average rate of change of f(x) on -3 ≤ x ≤ 3 is given to be
(f (3) - f (-3)) / (3 - (-3)) = -2.5
If f (-3) = 14, then
(f (3) - 14) / (3 + 3) = -2.5
(f (3) - 14) / 6 = -2.5
f (3) - 14 = -15
f (3) = -1
