Answer:
6.
Step-by-step explanation:
Since the y-value is the same, the two points make a horizontal line. You can think of it as a number line, where the first point is at -4 and the second is at 2. So, the distance between -4 and 2 is 6.

A pair of flip flops is $30. How much will they cost after a 20% discount and 6.5% tax?
Answer:
$6.39
Step-by-step explanation
well, 20% of $30 is $6, so then you just have to add on the tax, which is 39 cents, coming to $6.39
Answer:
25.56
Step-by-step explanation:
30 divided by 4 is 6 so 30- 6=24
6.5% of 24=1.56 sooooo 24+1.56=25.56

Mr. Bruce has some clay with a mass of 24 kilograms. If he puts the same amount of clay into 6 bags, how many grams of clay are in each bag? I NEED THE EXPLANATION
Answer:
4000grams in each bag
Step-by-step explanation:
Assume he put x amount of clay into each bag, he then put 6x into 6 bags.(since the question didn’t mention, I assume he put every clay he has into the bags)
6x=24kg
x=4kg
Since the question is asking for grams not kilograms:
4kg=4000g

Does this matrix have an inverse? Why or why not?
A = [16 - 2)
0
A.
Yes, because its determinant is zero.
a
B.
Yes, because its determinant is greater than zero.
o
C.
No, because its determinant is zero.
o
D.
No, because its determinant is less than zero.
Answer:
c
Step-by-step explanation:
The given matrix has a determinant of zero thus it will not have any inverse.
What is a matrix?matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.
In another word, a matrix is a set of variables that are arranged in such a good way that we can create an algebraic equation from that.
In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.
Given the matrix
[tex]\begin{bmatrix}16 & -4 \\8 & -2 \end{bmatrix}[/tex]
The determinant of this matrix is 16(-2) - (8)(-4)
⇒-32 + 32 = 0
Since the determinant of the given matrix is zero so there will be no inverse.
Hence "The given matrix has a determinant of zero thus it will not have any inverse".

There are 12 cans of soup in a carton. Each can has a
diameter of 8 cm and a height of 9 cm. How much paper, to
the nearest square centimeter, is needed to make labels that
wrap around each of the 12 cans? (Assume there is no
overlap.)
Answer:
The required amount of paper is 2715.23 [tex]cm^{2}[/tex].
Step-by-step explanation:
The cans of soup has a shape of a cylinder, so that;
The surface area around a cylinder = 2[tex]\pi[/tex]rh
Where: r is the radius of the can, and h is its height.
From the given question, diameter = 8 cm, then;
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{8}{2}[/tex]
r = 4 cm
Surface area around one of the cans = 2 x [tex]\frac{22}{7}[/tex] x 4 x 9
= 226.2857
Surface area around one of the cans = 226.28 [tex]cm^{2}[/tex]
So that, the total amount of paper required to make labels around each of the 12 cans can be determined by:
12 x 226.2857 = 2715.4284
The required amount of paper is 2715.23 [tex]cm^{2}[/tex].

Assume a significance level of α=0.01 and use the given information to complete parts (a) and (b) below. Original claim: The mean pulse rate (in beats per minute) of a certain group of adult males is 75 bpm. The hypothesis test results in a P-value of 0.0087. a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0.) Choose the correct answer below. A. Reject H0 because the P-value is less than or equal to α. B. Fail to reject H0 because the P-value is less than or equal to α. C. Fail to reject H0 because the P-value is greater than α. D. Reject H0 because the P-value is greater than α.
Answer:
A. Reject H0 because the P-value is less than or equal to α.
Step-by-step explanation:
Decision:
If the pvalue of the test is less than the significance level, we reject the null hypothesis H0.
Otherwise, we fail to reject the null hypothesis H0.
In this question:
Significance level: 0.01
P-value: 0.0087
0.0087 < 0.01, so we reject H0.
The correct answer is given by option A.

see attached graph - there are two real roots for y=2x^4-6x^2+10x-7
so 2x^4-6x^2+10x-7 can be expressed as:
(x - root1)(x - root2)(2x^2+Bx+C)
Answer:
Yes, it can be.
Step-by-step explanation:
Using solver program, the expression 2x^4-6x^2+10x-7 has:
two real roots at x≈-2.3888 and x≈1.1424
and
two complex roots at x≈0.62321 - 0.94559 i and x≈0.62321 + 0.94559 i
Because it has two real roots, the expression can be simplified.

Step-by-step explanation:
- Scores on an exam are normally distributed woth a population standard deviation of 5.6. A random sample of 40 scores on the exam has a mean of 32 estimate the population mean with - A) 80% confidence - B) 90% - C) 98%
Answer: i think i got b or c onr of them are correct :)
Step-by-step explanation:
The estimated population mean with
80% confidence = [30.856, 33.135]
90% confidence = [30.543, 33.456]
98% confidence = [29.94, 34.06]
What is confidence interval?For a population with unknown mean and known standard deviation , a confidence interval for the population mean, based on a simple random sample of size n, is [tex]\bar x +_{-}z^{*}\frac{\sigma}{\sqrt{n} }[/tex] , where z* is the upper (1-C)/2 critical value for the standard normal distribution.
Population standard deviation = 5.6
Sample mean = 32
Sample size = 40
Given confidence level = 80%
[tex]z^{*}[/tex] at 80% confidence level = 1.28
Upper confidence interval = 33.135
Lower confidence interval = 30.865
Population mean lies between [30.856, 33.135] at 80% confidence level.
Given confidence level = 90%
[tex]z^{*}[/tex] at 90% confidence level = 1.65
Upper confidence interval =33.456
Lower confidence interval = 30.543
Population mean lies between [30.543, 33.456] at 90% confidence level.
Given confidence level = 98%
[tex]z^{*}[/tex] at 98% confidence level = 1.65
Upper confidence interval = 34.06
Lower confidence interval = 29.94
Population mean lies between [29.94, 34.06] at 98% confidence level.
