Step-by-step explanation:
Solve the two-step equation.
14 = 31.7 – 3x
What is the solution?
Answer:
The answer is 5.9
Step-by-step explanation:
1) Subtract 31.7 from both sides.
[tex]14 - 31.7 = - 3x[/tex]
2) Simplify 14 - 31.7 to -17.7
[tex] - 17.7 = - 3x[/tex]
3) Divide both sides by -3.
[tex] \frac{ - 17.7}{ - 3} = x[/tex]
4) Simplify -17.7/-3 to 5.9
[tex]5.9 = x[/tex]
5) Switch sides.
[tex]x = 5.9[/tex]
Therefor, the answer is x = 5.9.

Suppose the family wise error rate is 0.05, if there are ten levels of one factor but only 5 comparisons are of importance, what would the individual error rate need to be for each of those 5 comparisons? Group of answer choices 5 0.01 .05 0.10
Answer:
Individual error rate = 0.01
Therefore, Option b) 0.01 is the correct answer
Step-by-step explanation:
Given the data in the question;
family wise error rate ∝ = 0.05
there are ten levels of one factor but
important comparisons m = 5
the individual error rate need to be for each of those 5 comparisons = ?
we know that;
individual error rate = family wise error rate ∝ / important comparisons m
so we substitute
individual error rate = 0.05 / 5
individual error rate = 0.01
Therefore, Option b) 0.01 is the correct answer

Jeremiah conducts a survey and finds that as the first variable in his survey increases, the
second variable in his survey decreases. What type of association is there between the
two variables in his survey?
Answer:
Negative Association.
Step-by-step explanation:
Association between variables:
Association between variables can be classified as positive or negative.
Positive: Both move in the same direction, that is, either both increase or both decrease.
Negative: The variables move in opposite directions, one increases and the other decreases.
In this question:
As the first increases the second decreases, that is, they move in opposite directions, so it is a Negative Association.

A study of 420,027 cell phone users found that 133 of them developed cancer of the brain or nervous system. Prior to this study of cell phone use, the rate of such cancer was found to be 0.0414% for those not using cell phones. Complete parts (a) and (b). a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system.
Answer: (0.00027144, 0.00036176)
Step-by-step explanation:
The sample proportion of cell phone users who develop cancer of the brain or nervous system = [tex]\dfrac{133}{420027}=0.0003166[/tex]
Sample size : 420027
Confidence interval for p: [tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex]= sample proportion , n= sample size , z* = crirical z value.
For 90% confidence interval , z*= 1.645
Required confidence interval:
[tex]0.0003166\pm (1.645)\sqrt{\dfrac{0.0003166(1-0.0003166)}{420027}}\\\\=0.0003166\pm 0.00004516\\\\=(0.0003166-0.00004516,\ 0.0003166+ 0.00004516)\\\\=(0.00027144, \ 0.00036176)[/tex]
A 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system = (0.00027144, 0.00036176)

Solve for t
4/3 = t/7
Answer:
[tex]\frac{28}{3}=t[/tex]
Step-by-step explanation:
[tex]\frac{4}{3}=\frac{t}{7}[/tex]
Use cross products to simplify the equation. Multiply the denominator of the second fraction by the numerator of the first fraction, and the denominator of the first fraction by the numerator of the second,
[tex](4)(7) = (3)(t)[/tex]
Simplify,
[tex]28=3t[/tex]
Inverse operations,
[tex]\frac{28}{3}=t[/tex]
solve the system by substitution......
Answer:
(4,8) is the answer.
Step-by-step explanation:
To solve by substitution, you need to isolate a variable. The bottom equation already has y isolated, so we can just plug that into the other equation:
[tex]2x=-2x+16[/tex]
Add [tex]2x[/tex] to both sides in order to get rid of the [tex]-2x[/tex] on the right side:
[tex]4x=16[/tex]
Now divide by 4 on both sides to get:
[tex]x=4[/tex]
That gives us our x. Now plug in that x into either equation. I will just choose the bottom equation:
[tex]y=2(4)\\y=8[/tex]
Therefore the solution to this problem is (4,8).

ZA and ZB are vertical angles. If mZA = (3.C – 9)° and m B = (x+3)°, then find the value of x.
Answer:
x = 6
Step-by-step explanation:
Vertical angles in a geometry are equal. Hence m<A = m<B
Given that
m<A = 3x - 9
m<B - x+3
Then 3x - 9 = x+3
3x - x = 3 + 9
2x = 12
Divide both sides by 2
2x/12 = 12/2
x = 6
Hence the value of x is 6

True or false?
When multiplying fractions, you flip the second fraction to solve.
True - Keep the first fraction the same then flip to solve the MULTIPLICATION problem
True - Only when the second number is a whole number
False - Only when the second number is a whole number
False - You ONLY flip the second fraction when you have a FRACTION DIVISION problem. Keep, change, flip.
Answer:
True - Keep the first fraction the same then flip to solve the MULTIPLICATION problem
Step-by-step explanation:
Answer:
It would be A, True - Keep the first fraction the same then flip to solve the MULTIPLICATION problem.

David wants to test a claim about a population mean. The population standard deviation is unknown, the sample is a simple random sample of size 20, and the population is normally distributed. In this case, the t-test should be used since σ is unknown. If David incorrectly uses the z-distribution instead of the t-distribution, will he obtain a P-value that is too big or too small? Explain your thinking. Will he be more likely or less likely to reject the null hypothesis than if had correctly used the t-distribution?
Answer:
a)The P-value will be too small
b) He will reject the Null hypothesis
Step-by-step explanation:
a) If David incorrectly uses the z-distribution instead of the t-distribution, he will obtain a p-value that is too small because p-values obtained using Z distribution are smaller when compared to p-values obtained using t-distribution
b) He will reject the Null hypothesis given that the P value he will obtain will be very different from the one he obtained using z-distribution
Choose the number sentence that illustrates the distributive property of multiplication over addition.

An airplane is flying from Redville to Leek.
The airplane flies 50 miles East and then 180 miles south.
How far is Leek from Redville directly?
The required distance of Leek from Reidville directly is 186.82 miles.
Given that,
An airplane is flying from Reidville to Leek. The airplane flies 50 miles East and then 180 miles south. How far is Leek from Reidville directly is to be determined.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
The direct distance can be given as,
x = √[50² + 180²]
x = √34900
x = 186.82
Thus, the required distance of Leek from Reidville directly is 186.82 miles.

if f(x)=6x-8, then f^-1(x)=
Answer:
f(x) is another way to write y.
You have y = 6x - 8.
To find the inverse, switch the x and the y and solve for the new y.
Switching gives you x = 6y - 8.
You add 8 to both sides to give you 6y = x + 8.
Divide both sides by 6 gives you the inverse as y =1/6x + 4/3

1219 kg of Swiss cheese is packaged in 3 kg bags. Will there be any cheese left over? How do you know?
Answer:
1 cheese is left over.
Step-by-step explanation:
Given that,
1219 kg of Swiss cheese is packaged in 3 kg bags.
i.e. 3 kg bags = 1219 kg of Swiss cheese
Implies, 1 kg bag = [tex]\dfrac{1219}{3}[/tex] kg of swiss cheese
If we divide 1219 by 3, we get [tex]46\dfrac{1}{3}[/tex]. Here, 46 is the quotient and 1 is the remainder.
It means 1 cheese is left over.
