Answer:
522 m^2
Step-by-step explanation:
I've circles the numbers that you actually need to solve this problem.
First, find the area of the bigger rectangle by multiplying the length and width.
24*21=504
Then find the area of the smaller rectangle the same way
3*6=18
then add them to get the total area
504+18=522
522 m^2

Answer: 36 and 22 A=396
Step-by-step explanation:
half of 1 diagonal is 18, so the whole diagonal is 36
the other diagonal half is 11 so the whole is 22
put 36 and 22 into the boxes
then solve
[tex]A=\frac{1}{2} (36*22)\\A=396[/tex]
Answer:
A = 99 in²
Step-by-step explanation:
Using the given formula with d₁ = 18 and d₂ = 11 , then
A = [tex]\frac{1}{2}[/tex] × 18 × 11 = 9 × 11 = 99 in²

A factory fills bottles with a beverage, and each bottle is supposed to contain 500\text{ mL}500 mL500, start text, space, m, L, end text. Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml. She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml. Norah wants to use these sample data to conduct a ttt test on the mean. Assume that all conditions for inference have been met.
Required:
Calculate the test statistic for Norah's test.
Answer:
The test statistic for Norah's test is [tex]t = -2[/tex]
Step-by-step explanation:
Norah is in charge of a quality control test that involves measuring the amounts in a sample of bottles to see if the sample mean amount is significantly different than 500 ml.
This means that at the null hypothesis we test if the sample mean is 500 ml, that is:
[tex]H_0: \mu = 500[/tex]
At the alternate hypothesis, we test if it is differente than 500 ml, that is:
[tex]H_a: \mu \neq 500[/tex]
The test statistic is:
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.
500 is tested at the null hypothesis:
This means that [tex]\mu = 500[/tex]
She takes a random sample of 16 bottles and finds a mean amount of 497ml, and a sample standard deviation of 6ml.
This means that [tex]n = 16, X = 497, s = 6[/tex]
Calculate the test statistic for Norah's test.
[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{497 - 500}{\frac{6}{\sqrt{16}}}[/tex]
[tex]t = -2[/tex]
The test statistic for Norah's test is [tex]t = -2[/tex]

Nancy's Cupcakes recorded how many cupcakes it recently sold of each flavor.
chocolate cupcakes 2
pistachio cupcakes 1
banana cupcakes 5
pumpkin cupcakes 6
Considering this data, how many of the next 21 cupcakes sold would you expect to be pumpkin cupcakes?
Answer:
pumpkin because it got the most sold
Answer:
9
Step-by-step explanation:
Knowing that
pumpkin = 6
Total =
chocolate cupcakes 2 + pistachio cupcakes 1 + banana cupcakes 5 +pumpkin cupcakes 6
Thus, 2 + 1 + 5 + 6 = 14
Cross multiply
[tex]\frac{6}{14}=\frac{x}{21}[/tex]
6 * 21 = 126
126/14 = 9
Hence, next 21 cupcakes sold that will be pumpkin cupcakes will 9 pumpkin cupcake

If the radius of a cylinder is 3 centimeters, then the area of one of the circular bases is 18.84 square centimeters. True False
Answer:
false
Step-by-step explanation:
Answer:
False
Step-by-step explanation:
To calculate the area of a circle you need to multiply the radius by itself, then multiply that number by [tex]\pi[/tex].
In this case, our radius is 3, so we multiply 3 × 3 × [tex]\pi[/tex] (which can be estimated as 3.14)
3×3 is 9
9×3.14 is 28.26
28.26≠18.84
So, the correct answer is false. Hope this helps ^.^

XYZ has vertices X(15,−8), Y(13, 21), and Z(−17, 17). Which of the following represents the translation of △XYZ along vector <−6, 5> and its reflection across the x-axis?
Answer:
X (15, −8) → X ′(9, −3) → X ″(9, 3);
Y (13, 21) → Y ′(7, 26) → Y ″(7, −26);
Z (−17, 17) → Z ′(−23, 22) → Z ″(−23, −22)
Step-by-step explanation:
Use the translation vector <−6, 5> to determine the rule for translation of the coordinates: (x, y)→ (x+(−6),y + 5).
Apply the rule to translate vertices X(15 ,−8), Y(13, 21) , and Z(−17, 17) .
X (15,−8) → (15 + (−6),−8 + 5) → X'(9, −3).
Y (13, 21) → (13+ (−6), 21 + 5) → Y' (7, 26).
Z (−17, 17) → (−17 + (−6), 17 + 5) → Z' (−23, 22).
To apply the reflection across x-axis use the rule for reflection: (x, y) → (x, −y).
Apply the reflection rule to the vertices of △X'Y'Z'.
X' (9, −3) → X'' (9, 3).
Y' (7, 26)→Y''(7, −26).
Z' (−23, 22) → Z'' (−23, −22).
Therefore,
X (15 ,−8) → X' (9, −3) → X'' (9, 3)
Y (13, 21) → Y' (7, 26) → Y'' (7, −26)
Z (−17, 17) → Z' (−23, 22) → Z'' (−23, −22)
represents the translation of △XYZ along vector <−6, 5> and its reflection across the x-axis.
You are conducting a significance test of H0: μ = 1.6 against Ha: μ ≠ 1.6. After checking the conditions are met from a simple random sample of 28 observations, you obtain t = 2.79. Based on this result, describe the p-value.
The p-value falls between 0.05 and 0.1.
The p-value falls between 0.0025 and 0.005.
The p-value falls between 0.02 and 0.025.
The p-value falls between 0.005 and 0.01.
The p-value is less than 0.005
The correct option is D)The p-value falls between 0.005 and 0.01.
What is p-value?
The P value denotes the probability that, when the null hypothesis is true, the statistical summary will be equal to or more extreme than the actual observed results for a specific statistical model.
The given that [tex]H_0[/tex]: μ = 1.6 and [tex]H_a[/tex]: μ ≠ 1.6. and n=28.
Degrees of freedom = n-1 = 28-1 = 27 This is two tailed test,
P(t>2.79)=1-P(t<2.79)
=> 1-0.9952
=> 0.0048.
P-value = 2*P(t>2.79)=2*0.0048=0.0096.
Hence the correct option is D)The p-value falls between 0.005 and 0.01.

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary
Answer:
5. 10 cm
6. 12 in
7. 5 mi
8. 13 cm
Step-by-step explanation:
5. 6² + 8² = x²
36 + 64 = x
36 + 64 = 100
√100 = 10
6. 15² - 9² = x²
225 - 81 = 144
√144 = 12
7. 3² + 4² = x²
9 + 16 = x
9 + 16 = 25
√25 = 5
8. 12² + 5² = x²
144 + 25 = x
144 + 25 = 169
√169 = 13

Look at the figure. How can you prove the triangles are congruent?
Answer:
SSS - The two triangles share all 3 sides, proving they are congruent.
Step-by-step explanation:
Two sides of each triangle are marked in the diagram as equal. The third side, [tex]\overline{BD}[/tex] is shared between both sides, meaning that both triangles share all three sides. This is known as SSS (side-side-side) and is a proof of congruence.
Step-by-step explanation:
In triangle ABD In triangle CBD
AB. = BC. [Given]
AD. = CD. [Given]
BD. = BD. [Common side]
Therefore,
According to SSS Congruence condition
Triangle ABD is congruent to Triangle CBD

Answer:
B (5t + 15 ≤ 140) is correct
Step-by-step explanation:
Because since each table (t) seats 5 people, you'd represent that as 5t (5 seats per table).
Since there is one extra table that seats 15 people, you'd represent that as 15.
Lastly, those two last steps added together should have to be less than or equal to (≤) 140 (the amount of people allowed in the building).
