A group of friends had 28 driveways to shovel. If one of them shoveled 1/4 of the driveways, how many driveways did he shovel.
Answer: 7
Step-by-step explanation:
Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.
The number of driveways that he shovel will be:
= 1/4 × 28
= 7
Therefore, he shovel 7 driveways.

Step-by-step explanation:
How many centimeters will Kristen have left to knit when Edie has 12 centimeters left to knit?
Enter your answer in the box.
Answer:
D ; 15 cm
Step-by-step explanation:
The graph which matches the distribution of the data is D. This can be known by visually pairing Kristen's data on the y-axis to Eddie's data on the x - axis.
The Numbe rof centimeters Kristen has left to knit when Eddie has 13 cm is about 15 cm. This can be obtained by tracing the poi t 12 upward and tracing its intersection with the best fit line to the y-axis.
Answer:
D ; 15 cm
Step-by-step explanation:
The graph which matches the distribution of the data is D. This can be known by visually pairing Kristen's data on the y-axis to Eddie's data on the x - axis.
The Numbe of centimeters Kristen has left to knit when Eddie has 13 cm is about 15 cm. This can be obtained by tracing the poi t 12 upward and tracing its intersection with the best fit line to the y-axis.
Jenny had 7 dimes and 3 pennies in her She takes a coin out from her pocket, looks at the coin and then replaces it her pocket before she removes a second coin. What is
the probability she will not take out a penny both times?
F. 3/10
G. 9/100
H. 49/100
J. 21/100
=========================================================
Explanation:
There are 7 dimes and 3 pennies, leading to 7+3 = 10 coins total.
The probability of not picking a penny is 7/10. If the first coin is put back, then the probability doesn't change for the second selection.
The probability of getting two dimes is (7/10)*(7/10) = 49/100 when the first coin is replaced.
If the first coin is not replaced, then the answer would be (7/10)*(6/9) = 42/90 = 7/15

Answer:
See Explanation
Step-by-step explanation:
Required
Complete the term and identify the rule
[tex](a)\ 5, 6, 8, [], 15[/tex]
We have:
[tex]5 + 1 = 6[/tex]
[tex]6 + 2 = 8[/tex]
[tex]8 + 3 = 11[/tex] --- Missing term
[tex]11 + 4 = 15[/tex]
The rule is:
Add current term to the position of term
i.e.
[tex]T_{n+1} = T_n + n[/tex]
[tex](b)\ 18, 20, 24, [], 38[/tex]
We have:
[tex]18 + 2*1 = 20[/tex]
[tex]20 + 2*2 = 24[/tex]
[tex]24 + 2 * 3 = 30[/tex] --- Missing term
[tex]30 + 2 * 4 = 38[/tex]
The rule is:
Add current term to twice the position of term
i.e.
[tex]T_{n+1} = T_n + 2 *n[/tex]
[tex](3)\ 14, 17, 20, 23, [][/tex]
We have:
[tex]14 + 3 = 17[/tex]
[tex]17 + 3 =20[/tex]
[tex]20 + 3 = 23[/tex]
[tex]23 + 3 = 26[/tex] --- Missing term
The rule is: Add 3
i.e.
[tex]T_{n+1} = T_n + 3[/tex]
[tex](4)\ 24, 30, 36, 42, [][/tex]
We have:
[tex]24 + 6 = 30[/tex]
[tex]30 + 6 = 36[/tex]
[tex]36 + 6 = 42[/tex]
[tex]42 + 6 = 48[/tex] --- Missing term
The rule is: Add 6
i.e.
[tex]T_{n+1} = T_n + 6[/tex]
[tex](5)\ 1, 10, 100[/tex]
We have:

reduce the fraction 512/128 into the simplest form.
Answer:
Therefore, 512/128 simplified to lowest terms is 4/1.
Step-by-step explanation:
Reduce 512/128 to lowest terms
The simplest form of
512
128
is
4
1
.
Steps to simplifying fractions
Find the GCD (or HCF) of numerator and denominator
GCD of 512 and 128 is 128
Divide both the numerator and denominator by the GCD
512 ÷ 128
128 ÷ 128
Reduced fraction:
4

1:3 multiply them by 4 for 4 juice cans
Answer:
The answer would be A, 12.
Step-by-step explanation:
The ratio of juice to water is 1:3. 1 being the amount of juice, and 3 being the amount of water. If Maria used 4 cans of juice, that makes the new ratio 4:w. W can stand for the amount of water. 1x4=4 so we can multiply 3x4=12.

The quality-control manager at a compact flourescent light bulb factory wants to test the claim that the mean life of a large shipment of cfls is equal to 6500 hours. the population standard deviation is 500 hours. a random sample of 50 cfls indicates a sample mean life of 6,700 hours and sample standard deviation is 600 hours.
Critical values, where P(Z > Z) - a and P(t >) - a 2016-1282 20.06-1645 20.02 -1.960 10.10. - 1.299 10.06.45 - 1677 foto - 2010 1.115 pt.
a. At the 0.05 level of significance, is there evidence that the mean life is different from 6,500 hours?
b. Compute the p value and interpret its meaning.
c. Construct a 95% confidence interval estimate of the population mean life of the CFLs.
d. Compare the results of (a) and (c). What conclusions do you reach?
Answer:
a. At the 0.05 level of significance, there is evidence that the mean life is different from 6,500 hours.
b. The p value= ≈ 0.00480 for z- test which is less than 0.05 and H0 is rejected .
The p value= 0.006913 for t- test which is less than 0.05 and H0 is rejected for 49 degrees of freedom.
c. CI [6583.336 ,6816.336]
d. The range of CI [6583.336 ,6816.336] tells that the cfls having a different mean life lie in this range.
Step-by-step explanation:
Population mean = u= 6500 hours.
Population standard deviation = σ=500 hours.
Sample size =n= 50
Sample mean =x`= 6,700 hours
Sample standard deviation=s= 600 hours.
Critical values, where P(Z > Z) =∝ and P(t >) =∝
Z(0.10)=1.282
Z(0.05)=1.645
Z(0.025)=1.960
t(0.01)(49)= 1.299
t(0.05)= 1.677
t(0.025,49)=2.010
Let the null and alternate hypotheses be
H0: u = 6500 against the claim Ha: u ≠ 6500
Applying Z test
Z= x`- u/ s/√n
z= 6700-6500/500/√50
Z= 200/70.7113
z= 2.82=2.82
Applying t test
t= x`- u /s/√n
t= 6700-6500/600/√50
t= 2.82
a. At the 0.05 level of significance, there is evidence that the mean life is different from 6,500 hours.
Yes we reject H0 for z- test as it falls in the critical region,at the 0.05 level of significance, z=2.82 > z∝=1.645
For t test we reject H0 as it falls in the critical region,at the 0.05 level of significance, t=2.82 > t∝=1.677 with n-1 = 50-1 = 49 degrees of freedom.
b. The p value= ≈ 0.00480 for z- test which is less than 0.05 and H0 is rejected .
The p value= 0.006913 for t- test which is less than 0.05 and H0 is rejected for 49 degrees of freedom.
c. The 95 % confidence interval of the population mean life is estimated by
x` ± z∝/2 (σ/√n )
6700± 1.645 (500/√50)
6700±116.336
6583.336 ,6816.336
d. The range of CI [6583.336 ,6816.336] tells that the cfls having a different mean life lie in this range.

What is the area of the triangle?
Answer:
21
Step-by-step explanation:
Add 5.3 + 1.7 and you get 7 (7 is the base of the triangle). Multiply 7 by the height (6) and you get 42. When you put 2 triangles together, it will create a quadrilateral. "Cut the quadrilateral in half" and you will get your triangle's area. The area is 21 :)
Answer:
53.9 square units was my answer, but I learned that it was 21 !
"Snoqualmie" is a name shared by a waterfall and a tribe of Native Americans. In a study of the cultural importance of the waterfall, two groups of the Snoqualmie tribe were randomly surveyed. One group consisted of Snoqualmie members living less than 25 miles from the waterfall. Another group consisted of Snoqualmie members living more than 25 miles from the waterfall. The researchers asked each member to rate the cultural importance of the waterfall as low, medium, or high. Data from the study are presented in the following table.
Members Living More Than 25 Miles from the Waterfall Members Living Less Than 25 Miles from the Waterfall Total
Low 25 17 42
Medium 8 21 29
High 5 12 17
Total 38 50 88
Required:
If the distributions of ratings are the same for those Snoqualmie members living less than 25 miles from the waterfall and those living more than 25 miles from the waterfall, what is equal to the expected count of members living less than 25 miles from the waterfall who rated the cultural importance as high?
Answer:
Expected count frequency= 17*50/88= 9.659
Step-by-step explanation:
Members Living More Members Living Less Total
Than 25 Miles Than 25 Miles
from the Waterfall from the Waterfall
Low 25 17 42
Medium 8 21 29
High 5 12 17
Total 38 50 88
We see that the total of the high row is 17 and the total of the members living less than 25 miles from the waterfall is 50 .
So using the formula :
Expected count frequency= row total * column total/ grand total
= 17*50/88= 9.659
All the expected frequencies can be found in a similar way and then compared to the observed frequency to test the chi square.
