What is the volume of the rectangular prism? . choices: (63yd^3) (7yd^3) (22.5yd^3) (189yd^3)
Answer: (7yd^3)
Step-by-step explanation:
Width= [tex]3*\frac{1}{3}[/tex]
Length= [tex]7*\frac{1}{3}[/tex]
Height= [tex]9*\frac{1}{3}[/tex]
Width= 1
Length= 2.33333333333...
Height= 3
1*2.33333333333*3= 6.99999999999
6.99999999999 is round up to 7
So that would be (7yd^3)
Answer:
Step-by-step explanation:
I just did the test. Answer is 7yd

What are the other side lengths of the triangle?
9514 1404 393
Answer:
24, 26
Step-by-step explanation:
The shortest side of the given triangle is 10 units, so the similar triangle is larger by a factor of 20/10 = 2. The other two sides of the similar triangle are both 2 times the other two sides of the given triangle:
2×12 = 24
2×13 = 26
The other side lengths are 24 and 26 units.

31.40
what explicit formula describes the pattern of this table
Answer:
y - 6.28 = 3.14( x - 2 )
Step-by-step explanation:
Notice that 6.28 is twice the approximate value of pi: 2(3.14), and that
9.42 is three times pi. We can deduce immediately that the slope of the line passing through (2, 6.28) and (3, 9.42) is 3.14.
Using the point-slope formula for the equation of a straight line, we get:
y - 6.28 = 3.14( x - 2 )
Which pair of expressions is equivalent using the Associative Property of Multiplication?
A. 4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
B. 4(2a ⋅ 5) = 8a ⋅ 20
C. 4(2a ⋅ 5) = (2a ⋅ 5) ⋅ 4
D. 4(2a ⋅ 5) = 4 ⋅ 2a ⋅ 5
Answer:
4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Step-by-step explanation:
Let A, B and C be the required expression, according to Associative property;
(A+B)+C = A+(B+C)
This shows that no matter the sum of values in parenthesis, it does not alter the values at both sides.
From the given expression, the expression that is equivalent using the Associative Property of Multiplication is 4(2a ⋅ 5) = (4 ⋅ 2a) ⋅ 5
Note that the product of the values in bracket do not affect the final values
4(2a ⋅ 5) = 4(10a) = 40a
(4 ⋅ 2a) ⋅ 5 = 8a ⋅ 5 = 40a
You can see that both expressions gives the same values

Step-by-step explanation:
A nutritionist suspected that her company's clients had below average cholesterol. They obtained a random sample of 8 clients of the same age and gender. These clients had a mean cholesterol level of xˉ=4.28 mmol/L (millimoles per liter).
To see how likely a sample like this was to happen by random chance alone, the nutritionist performed a simulation. They simulated 60 samples of n=8 cholesterol levels from a normal population with a mean of 4.6 mmol/L and a standard deviation of 0.5 mmol/L (these are generally accepted values for people with the same age and gender of those in the sample). They recorded the mean of the cholesterol levels in each sample. Here are the sample means from their 60 samples:
They want to test H0:μ=4.6 mmol/L vs. Ha:μ<4.6 mmol/L where μ is the mean cholesterol level for all clients like those sampled.
Based on these simulated results, what is the approximate p-value of the test?
Note: The sample result was xˉ=4.28 mmol/L.
Answer:
p-value ≈ 0.05
Step-by-step explanation:
Regardless of age, about 20% of American adults participate in fitness activities at least twice a week. A random sample of 100 adults over 40 years old found 15 who exercised at least twice a week. Is this evidence of a decline in participation after age 40? Use α = .05. a) Write test hypothesis b) Compute test statistic. c) Apply any method to draw conclusion.
Answer:
The null hypothesis is [tex]H_0: p = 0.2[/tex]
The alternate hypothesis is [tex]H_a: p < 0.2[/tex]
The p-value of the test is 0.1056 > 0.05, which means that there is not evidence of decline in participation after age 40 using α = 0.05.
Step-by-step explanation:
20% of American adults participate in fitness activities at least twice a week. Test if there is evidence of a decline in participation after age 40.
At the null hypothesis, we test that the proportion is of 0.2, so:
[tex]H_0: p = 0.2[/tex]
At the alternate hypothesis, we test if the proportion is less than 0.2, indicating a decline. 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.
20% is tested at the null hypothesis:
This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8}[/tex]
A random sample of 100 adults over 40 years old found 15 who exercised at least twice a week.
This means that [tex]n = 100, X = \frac{15}{100} = 0.15[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{0.15 - 0.2}{\frac{\sqrt{0.2*0.8}}{\sqrt{100}}}[/tex]
[tex]z = -1.25[/tex]
P-value of the test:
The p-value of the test is the probability of finding a sample proportion below 0.15, which is the p-value of z = -1.25.
Looking at the z-table, z = -1.25 has a pvalue of 0.1056.
The p-value of the test is 0.1056 > 0.05, which means that there is not evidence of decline in participation after age 40 using α = 0.05.

Step-by-step explanation:
A middle school coach wrote down the time, in seconds, of her students’ 100-meter dash as shown in the table. Student Time -(seconds … ) Gary 11.9 Rick 12.3 Phillip 13.5 Jorge 12.0 Robert 12.3 Jeremy 16.0 If the slowest time and the fastest time are removed from the data, how does the new mean compare to the mean of the ..
Answer:
D. The mean would decrease as there is less variability in the data.
Step-by-step explanation:
So, let’s find the mean with all of those numbers. First of all we should order them from least to greatest.
11.9, 12.0, 12.3, 12.3, 13.5, 16.0
We add them all up, and get 78! Once we get this total, we must divide it by how many numbers there are! There are six numbers, so 78/6.
78/6 is equal to 13. So the mean for all those numbers is 13.
Now let’s find the mean if we cross out the greatest and least numbers, the greatest number is 16.0, and the least number Is 11.9.
So, our new data set is:
12.0, 12.3, 12.3, 13.5
Add those all up to get 50.1
Divide the total by the numbers we got left, which is 4!
50.1/4 is equal to 12.525.
So the mean of our new data set is 12.525!
So that’s how I got the answer, have a nice day! Please tell me if I’m wrong!
12.525 < 13
