?

2 ft
3 ft)
5 ft
3 ft)
12 ft
Please
Answer:48 ft to the second power
Step-by-step explanation:
I just got it right on iready
The area of the outdoor carpet that needed for the hole should be considered as the 48 ft².
Calculation of the area:
Since
we know that
Area of the rectangle = Length (breadth)
here,
L = 12 ft
b = 5 ft
So,
area = 12 × 5
= 60 ft²
Now
The cut off triangle area
area = 1/2 × base × height
= 1/2 × 4 × 3
= 12/2
= 6 ft²
Now
The cut off rectangle area should be
area = Lb
= 3 × 2
= 6 ft²
Now finally
The area of the outdoor carpet should be
= 60 - 6 - 6
= 48 ft²

need to solve vertex angle
Answer:
Step-by-step explanation:
I don’t know what was going on with those middle angles but adjacent angles must sum to 180 which 100 and 30 does not satisfy. The two upper angles must be (360-2(84))/2=96. It follows that the lower adjacent angles must be 180-96=84, just like the angles at top. Anyway the angle j must satisfy
j+2(84)=180
j+168=180
j=12 degrees
Each of the following statements is correct in at least one number system. That is, the statement is correct if we assume the numbers are expressed in a base other than 10. It is up to you to find out which number base makes each statement correct. You need to justify your answer by converting the numbers in each operation to base 10 and showing that the statement is correct. For example, 36/6 = 7 is clearly not correct in base 10, but it is correct in base 12 because 3612 = 4210 and 4210/610 = 710.
Thus, 3612/612 = 712 is true.
a) 42/3 = 13
b) 23 + 44 + 14 + 32 = 223
Answer:
(a) Base 7
(b) Base 5
Step-by-step explanation:
(a) 42/3 = 13 testing base 7 we have:
4x7¹ + 2x7° = 28 + 2 = 30
3x7° = 3
1x7¹ + 3x7° = 7 + 3 = 10
30/3 = 10. Therefore, 42/3 = 13 is in base 7.
(b) 23 + 44 + 14 + 32 = 223. Testing base 5 we have:
2x5¹ + 3x5° = 10 + 3 = 13
4x5¹ + 4x5° = 20 + 4 = 24
1x5¹ + 4x5° = 5 + 4 = 9
3x5¹ + 2x5° = 15 + 2 = 17
2x5² + 2x5¹ + 3x5° = 50 + 10 + 3 = 63
13+24+9+17 = 63.
Therefore, it was done in base 5.

Rick and Lisa each have their own cookie jar Rick's cookie jar is 7/8 full and Lisa is 5/8. Fraction represents how much more of Rick's jar is full than Lisa?
Answer:
2/8 is the right answer your welcome
2/8 of a jar more full.
Tip: ALWAYS circle the numbers or key information to get the best results.
Watch what happens!
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Some key information in this problem is 7/8, and 5/8.
Since they asked us how much more and what fraction represents it, we should subtract 5/8 from 7/8 to find how much more full Rick's jar is than Lisa's.
7/8 - 5/8 = 2/8
So in summary, Rick's jar is 2/8 more full than Lisa's jar.

A letter home to the parents of seniors at Westgate High School says, "a simple random sample of 30 Westgate seniors that took the SAT-M test this year produced a mean of 512 and a standard deviation of 95. A confidence interval for the true mean for all WHS seniors is 512.00 ± 47.8." The confidence level for this interval is Group of answer choices
Answer:
It's 99%
Step-by-step explanation:
It just is.
A confidence interval for the true mean for all WHS seniors is 512.00 ± 47.8." The confidence level for this interval is 99%. The correct option is D.
What is the percentage?The percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal components are regarded to make up the whole.
A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Divide the amount by the total value to get the percentage, then multiply the resulting number by 100.
Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Therefore, the correct option is D, 99%.

Calculate the sample variance and sample standard deviation for the following frequency distribution of heights in centimeters for a sample of 8-year-old boys. If necessary, round to one more decimal place than the largest number of decimal places given in the data. Heights in Centimeters Class Frequency 116.1 - 120.0 38 120.1 - 124.0 24 124.1 - 128.0 28 128.1 - 132.0 43 132.1 - 136.0 29
Answer:
[tex]s^2 = 0.9938[/tex] --- sample variance
[tex]s = 0.9969[/tex] --- sample standard deviation
Step-by-step explanation:
Given
[tex]\begin{array}{cc}{Heights} & {Frequency} & {116.1-120.0} & {38} & {120.1-124.0} & {24} &{124.1-128.0} & {28} & {128.1-132.0} & {43} & {132.1-136.0} & {29} \ \end{array}[/tex]
Required
Calculate the sample variance and sample standard deviation
First, we calculate the midpoint of each class:
[tex]\begin{array}{ccc}{Heights} & {Frequency} & {m} &{116.1-120.0} & {38} & {118.05}& {120.1-124.0} & {24}& {122.05} &{124.1-128.0} & {28} &{126.05}& {128.1-132.0} & {43} & {130.05} &{132.1-136.0} & {29} &{134.05}\ \end{array}[/tex]
The midpoints are calculated by taking the average of the class intervals.
For instance:
Class 116.1 to 120.0 has a midpoint of
[tex]m = \frac{1}{2}(116.1+120.0)[/tex]
[tex]m = \frac{1}{2}(236.1)[/tex]
[tex]m = 118.05[/tex]
The same approach is applied to other classes.
Next, is to calculate the mean:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
In this case, it is:
[tex]\bar x = \frac{\sum fm}{\sum f}[/tex]
Where
[tex]m = midpoint[/tex]
So, we have:
[tex]\bar x = \frac{118.05*38+122.05*24+126.05*28+130.05*43+134.05*29}{38+24+28+43+29}[/tex]
[tex]\bar x = \frac{20424.10}{162}[/tex]
[tex]\bar x = 126.07[/tex]
The sample variance (s^2) is:
[tex]s^2 = \frac{\sum(m - \bar x)^2}{\sum f -1}[/tex]
This gives:
[tex]s^2 = \frac{(118.05-126.07)^2+(122.05-126.07)^2+(126.05-126.07)^2+(130.05-126.07)^2+(134.05-126.07)^2}{38+24+28+43+29-1}[/tex]
[tex]s^2 = \frac{160.002}{161}[/tex]
[tex]s^2 = 0.9938[/tex]
The sample standard deviation (s) is:
[tex]s = \sqrt{s^2[/tex]
[tex]s = \sqrt{0.9938[/tex]
[tex]s = 0.9969[/tex]

(11, r) lie on a line with slope 4. Find the missing coordinate r.
HELP ME PLEASE ITS DUE IN 2 HOURS I NEED HELPPP I WILL MARK BRAINLIEST HELPPP PLSSSSS
Answer:
[tex]r=-3[/tex]
Step-by-step explanation:
The line that passes through the two points (6, -23) and (11, r) has a slope of 4.
We want to determine the missing value of r.
We can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:
[tex]\displaystyle \frac{r-(-23)}{11-6}=4[/tex]
Simplify and evaluate:
[tex]\displaystyle \frac{r+23}{5}=4[/tex]
Multiply both sides by 5:
[tex]r+23=20[/tex]
Therefore:
[tex]r=-3[/tex]
