Answer:
13 units is the answer.
Step-by-step explanation:
points (8,-4) and (3,8)
We can rewrite the Pythagorean theorem as,
[tex]d=\sqrt{(x_2 - x_1)^2+(y_2-y_1)^2} \\\\d= \sqrt{(3-8)^2 + (8-(-4))^2} \\\\d=\sqrt{(-5)^2 + (12)^2} \\\\d=\sqrt{25 + 144} \\\\d=\sqrt{169} \\\\d=13\\\\[/tex]
∴ distance between 2 points (8,-4) and (3,8) = 13 units.

64-34=30
30÷2=15
so the answer is 15
The zeroes of the function are
-2 and 0
0 and 4
-2, 0, and 4
1. x=-2, x=0
So, the equation in factored form would be x(x+2)=0.
2. x=0, x=4
So, the equation in factored form would be x(x-4)=0.
3. x=-2, x=0, x=4
So, the equation in factored form would be x(x+2)(x-4)=0.

Answer:
10) 7 meters
11) 10 yards
12) 452.16 inches²
13) 235.5 meters²
14) 22608 centimeters²
15) 4220.16 centimeters²
16) 1177.5 centimeters²
17) 141.3 millimeters²
Step-by-step explanation:
10) The volume of a rectangular prism is calculated by multiplying the height, width, and length of the shape. In this question, we have the volume, the width, and height, but not the length. To find it, we can divide the width and height from the volume.
First, divide the width.
[tex]\frac{210}{5}[/tex] = 42
Next, the height.
[tex]\frac{42}{6}[/tex] = 7
The length of the shape is 7 meters.
----------------------------------------------------------------------------------------------------------------
11) For this question, we can do the same thing. Take the volume, then divide the length and width from it.
[tex]\frac{360}{6}[/tex] = 60
[tex]\frac{60}{6}[/tex] = 10
The height is 10 yards.
----------------------------------------------------------------------------------------------------------------
12) We have to find the volume of a cylinder. The formula for this is [tex]V=\pi r^2h[/tex]. We will use 3.14 for pi. The radius is 4 in and the height is 9 in. We can plug our values into the equation and solve.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](4²)(9)
V = 3.14(4²)(9)
V = 50.24(9)
V = 452.16
The volume is 452.16 inches².
----------------------------------------------------------------------------------------------------------------
13) We will use the same formula for this. Our radius is 5 m and the height is 3 m. Plug the values in and solve.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](5²)(3)
V = 3.14(5²)(3)
V = 78.5(3)
V = 235.5
The volume of this cylinder is 235.5 meters².
----------------------------------------------------------------------------------------------------------------
14) The radius of this cylinder is 15 cm. The height is 32 cm. Put these numbers into our formula.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](15²)(32)
V = 3.14(15²)(32)
V = 708.5(32)
V = 22608
The volume of this cylinder is 22608 centimeters².
----------------------------------------------------------------------------------------------------------------
15) The next cylinder has a radius of 8 cm and a height of 21 cm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](8²)(21)
V = 3.14(8²)(21)
V = 200.96(21)
V = 4220.16
The cylinder has a volume of 4220.16 centimeters².
----------------------------------------------------------------------------------------------------------------
16) This cylinder has a radius of 5 cm and a height of 15 cm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](5²)(15)
V = 3.14(5²)(15)
V = 78.5(15)
V = 1177.5
The volume is 1177.5 centimeters².
----------------------------------------------------------------------------------------------------------------
17) The dimensions of this cylinder are 3 mm and 15 mm.
V = [tex]\pi[/tex]r²h
V = [tex]\pi[/tex](3²)(15)
V = 3.14(3²)(15)
V = 9.42(15)
V = 141.3
The volume is 141.3 millimeters².

Ian has 22 ounce iced tea. He drinks 10 ounces. Enter the percentage of ounces Ian has left of his iced tea. Round your answer to the nearest hundredth
Answer:
54.55%
Step-by-step explanation:
If he drank 10 ounces, that means he has 12 ounces of the tea left.
Find the percent that he has left by dividing 12 by 22, and multiplying it by 100
(12/22) x 100
= 54.55
So, Ian has approximately 54.55% left of his iced tea

which expression is equivalent to 2(3x-4)
Answer:
6x-8
Step-by-step explanation:
2*3x=6x
2*-4= -8
6x-8
The Equivalent Expression of 2(3x-4) is 6x- 8.
What is Expression?Mathematical statements are called expressions if they have at least two terms that are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.
Given:
2(3x-4)
Using the Distributive Property
a x (b+ c)= (a x b)+ ( a x c)
So, 2(3x-4)
=2(3x)- 2(4)
= 6x - 8
Hence, the Equivalent Expression is 6x- 8.

Find the length of each trapezoid.
Answer:
EF = 27
Step-by-step explanation:
(x + 34)/2 = 2x - 13
x+ 34 = 4x - 26
3x = 60
x = 20
EF = 2(20) -13 = 27
Answer:
11. EF = 27
Step-by-step explanation:
11.
Median of a trapezoid:
2x - 13 = 20 + x + 14
2
2(2x - 13) = 20 + x + 14
4x - 26 = 34 + x
4x - x = 34 + 26
3x = 60
x = 20
EF = 2x - 13
EF = 2(20) - 13
EF = 40 - 13
EF = 27
Suppose 229 subjects are treated with a drug that is used to treat pain and 52 of them develop nausea use a 0.01 significance level to test the claim that more than 20% of users develop nausea identify the Noel and alternative hypothesis for this test
Answer:
The null hypothesis is [tex]H_o: p \leq 0.2[/tex]
The alternate hypothesis is [tex]H_a: p > 0.2[/tex]
The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.
Step-by-step explanation:
Test the claim that more than 20% of users develop nausea
This means that the null hypothesis is that 20% or less of the users develop nausea, that is:
[tex]H_o: p \leq 0.2[/tex]
And the alternate hypothesis is that more than 20% develop, so:
[tex]H_a: p > 0.2[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
0.2 is tested at the null hypothesis:
This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8}[/tex]
Suppose 229 subjects are treated with a drug that is used to treat pain and 52 of them develop nausea.
This means that [tex]n = 229, X = \frac{52}{229} = 0.2271[/tex]
Value of the test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.2271 - 0.20}{\frac{\sqrt{0.2*0.8}}{\sqrt{229}}}[/tex]
[tex]z = 1.03[/tex]
Pvalue of the test an decision:
Probability of finding a proportion above 0.2271, which is 1 subtracted by the pvalue of z = 1.03
Looking at the z-table, z = 1.03 has a pvalue of 0.8485
1 - 0.8485 = 0.1515
The pvalue of the test is 0.1515 > 0.01, which means that we do not reject the null hypothesis that 20% of less users develop nausea, that is, we have no sufficient evidence that this proportion is larger than 20%.

40% of the children are girls.
The ratio of adults to children is 2:3
How many of the children attending are boys?
Can someone plz help me with this
Answer:
1000 children
Step-by-step explanation:
Find the total units of adults and children = 2 + 3 = 5
5 units = 5000
1 unit = 5000 ÷ 5 = 1000
100% ÷ 5 units = 20% each unit
3 units = 20% x 3 = 60%
Since we all know that 60% of the people are children and 40% of the children are girls...
60 - 40 = 20%
20% = 1000

Answer:
No
Step-by-step explanation:
Fractions and decimals are not considered integers
7. The following numerical ordered sequence of numbers has a mean of 13 and a median of 14. 4. a. 8. 10. 13.b. 16. 18. 20:21 Gven this information, the values of a ondo must be:
Answer:
a = 9
b = 19
Step-by-step explanation:
DO B FIRST
The mean is the average of all the terms (numbers) in the sequence
To find the average you find the sum of the terms and divided the sum by the number of terms there are.
The mean times the number of terms equals the sum of all the terms subtract the terms that you know from the sum to get A
a = 17(10)-7-12-15-17-19-20-22-24-25
a = 170-161
a = 9
The median is found by taking the average of the two middle terms
Our middle terms are 17 and B
the median times 2 equals the sum of the two terms and then subtract the term you know from the sum
b = 18(2)-17
b = 36-17
b = 19
