An occupational safety officer for a large company is conducting a study to investigate back problems in office workers who use a computer for most of the workday. The study will
investigate the difference in back problems for workers who stand and workers who sit. A group of 68 volunteers have agreed to participate in the nine-month study. Half the group
is randomly assigned to work while standing, and the other half is assigned to work while sitting. At the end of the study, the mean number of back problems between the two
groups will be calculated. The officer will use the results to estimate the difference in the mean number of back problems between those who work while standing and those who
work while sitting

Considering the situation described, the appropriate test is given by:
E) A two sample t-interval for difference between population means.
When to use the t-distribution and the z-distribution?If we have the standard deviation for the sample, the t-distribution is used.If we have the standard deviation for the population, the z-distribution is used.In this problem, we will have the data from the sample, hence it is a t-test. We will compare the population means of the two groups, hence a two-sample t-interval is used, and option E is correct.

Danielle poured 3/4 gallon of water from a 7/8 gallon bucket.How much water is left in the bucket?
Answer:
1/8
Step-by-step explanation:
3/4 = 6/8 after you multiply top and bottom by 2
Subtract 3/4 from 7/8 and we get
7/8 - 3/4 = 7/8 - 6/8 = (7-6)/8 = 1/8
There is 1/8 of a gallon left
A basketball team played 65 games. The ratio of the number of games they won to the number of games they lost 4:3. How many games did they win? How did games did they lose ?
Answer:
Let L be the number of losses. T is the total number of games, and it has the value 64. W is the number of wins.
They won 28 more than they lost, so W = L + 28.
Since W = L + 28, W = 18 + 28 = 46.

Some steps are shown in converting the following conic inequality from general form to standard form. Complete the conversion and identify the shape, key feature, and which ordered pair is part of the solution set.
Answer:
hyperbola with a solid line boundary
(4, -2)
(0, -4)
Step-by-step explanation:
Took one for the team Edge 2021
The shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .
What is conic section ?Conic section is a curve obtained by the intersection of the surface of a cone with a plane.
we have,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
And,
The general form of a Conic Section is,
[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]
And,
The Standard form of a is,
[tex]\frac{(x-h)^2}{a^2} +\frac{(y-k)^2}{b^2} =1[/tex]
So,
Now,
[tex]4x^2-32x-9y^2-36y-8\leq 0[/tex]
Then,
[tex]4x^2-32x-9y^2-36y\leq8[/tex]
Now, taking common,
[tex]4(x^2-8x)-9(y^2+4y)\leq8[/tex]
Now,
Adding 64 and subtracting 36 to both sides ,
We get,
[tex]4(x^2-8x+16)-9(y^2+4y+4)\leq8+64-36[/tex]
Now,
factor the perfect square,
i.e.
[tex]x^2-8x+16=(x-4)^2[/tex]
Now,
[tex]y^2+4y+4=(y+2)^2[/tex]
Now,
[tex]4(x-4)^2-9(y+2)^2\leq36[/tex]
Now,
Divide both sides by 36,
i.e.
[tex]\frac{4(x-4)^2}{36} -\frac{9(y+2)^2}{36} \leq\frac{36}{36}[/tex]
We get,
[tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex]
So, this is the standard form of the given cubic inequality.
Hence, we can say that the shape of the given equation is hyperbola with solid line boundary, key feature i.e. the center is at (4, -2), and ordered pair is (0, -4) and the standard form will be [tex]\frac{(x-4)^2}{9} -\frac{(y+2)^2}{4} \leq1[/tex] .

one integer is 6 more than another. their product is 216. find the integers.
Answer:
-18 and -12
Or, 18 and 12
Step-by-step explanation:
Let the integers be 'a' & 'a + 6'.
Their product = 216
=> a x (a + 6) = 216
=> a² + 6a = 216
=> a² + 6a - 216 = 0
=> a² + (18 - 12)a - 216 = 0
=> a² + 18a - 12a - 216 = 0
=> a(a + 18) - 12(a + 18) = 0
=> (a + 18)(a - 12) = 0
=> a = - 18 or a = 12
Integers are: -18 and -18+6 = -12
Or, 12 and 12 + 6 = 18

Mariana is making a large pot of pasta. She mixes together 5 pounds of pasta, 6 pounds of sauce, and
45 pounds of onions
To find out how many z pound servings can she make, which two equations would you need?
Answer:
B
Step-by-step explanation:
The equations we need are:
(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.
(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
To find out how many 1/2-pound servings of pasta Mariana can make, we need to divide the total weight of pasta, sauce, and onions by 1/2.
Therefore, we need the equation:
(5(1/8) + 6 + 4(7/8)) ÷ (1/2) = ?
Simplifying the expression inside the parentheses, we get:
(41/8) ÷ (1/2) = ?
To divide by a fraction, we can multiply by its reciprocal. Therefore:
(41/8) ÷ (1/2) = (41/8) x (2/1) = 82/8 = 10(1/4)
So Mariana can make 10(1/4) servings of pasta.
Therefore,
The equations we need are:
(5(1/8) + 4(7/8) +6 = 16) to find the total weight of pasta, sauce, and onions.
(41/8) ÷ (1/2) = ? to find how many 1/2 pound servings Mariana can make.

. Do the points P (-2, -3), Q (4, 1) and R (2, 4) form a right triangle?
Answer:
Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Right triangle:
Sum of the squares of the two smaller sides is equal to the square of the largest side(Pythagorean theorem).
Length of side PQ:
P (-2, -3), Q (4, 1)
[tex]a = \sqrt{(4 - (-2))^2+(1 - (-3))^2} = \sqrt{6^2 + 4^2} = \sqrt{52}[/tex]
Length of side PR:
P (-2, -3), R (2,4)
[tex]b = \sqrt{(2 - (-2))^2+(4 - (-3))^2} = \sqrt{4^2 + 7^2} = \sqrt{65}[/tex]
Length of side QR
Q (4, 1), R (2,4)
[tex]c = \sqrt{(2 - 4)^2+(4 - 1)^2} = \sqrt{2^2 + 3^2} = \sqrt{13}[/tex]
Pythagorean Theorem:
Smaller sides: a and c
Largest side: b
So
[tex]a^2 + c^2 = b^2[/tex]
[tex](\sqrt{52})^2 + (\sqrt{13})^2 = (\sqrt{65})^2[/tex]
[tex]52 + 13 = 65[/tex]
[tex]65 = 65[/tex]
Since the length of the sides respects the Pythagorean theorem, these points form a right triangle.
