a man gets $312 for working 48 hours a week. how much does he get when he works 36 hours a week?
Answers
Answer:
$234
Step-by-step explanation:
Create a proportion where x is the amount he gets working 36 hours
[tex]\frac{312}{48}[/tex] = [tex]\frac{x}{36}[/tex]
Cross multiply and solve for x
48x = 11232
x = 234
So, when he works 36 hours a week, he will get paid $234
Answer:
assuming he is paid hourly?
312÷48= 6.50/hour
so, 6.50÷36= $234

Answers
Answer:
c) inversely
Step-by-step explanation:
In Mathematics an inverse relationship can be defined as a relationship between two variables, in which an increase in the value of one variable leads to a decrease in the value of the other variable i.e as the value of one variable becomes large, the value of the other variable becomes small.
Mathematically, an inverse relationship is given by the formula;
A = K/B
Where;
A and B are the variables.
K is the constant of proportionality.
Hence, if an increase in one quantity brings about a corresponding decrease in the other and vice versa, then the two quantities vary inversely.
Write an equation of the line that passes through a pair of points:
(-5, - 2), (4, 5)
Answers
Answer (assuming it can be written in slope-intercept form):
[tex]y = \frac{7}{9} x+\frac{17}{9}[/tex]
Step-by-step explanation:
1) First, find the slope of the line. Use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the given points into the formula and solve:
[tex]m = \frac{(5)-(-2)}{(4)-(-5)} \\m = \frac{5+2}{4+5} \\m = \frac{7}{9}[/tex]
So, the slope is [tex]\frac{7}{9}[/tex].
2) Now, use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to write the equation of the line. Substitute [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{7}{9}[/tex] for it. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line intersects, choose from any one of the given points (it doesn't matter which one, either way the result equals the same thing) and substitute its x and y values into the formula as well. (I chose (4,5), as seen below.) From there, isolate y to place the equation in slope-intercept form ([tex]y = mx + b[/tex] format) and find the following answer:
[tex]y-(5) = \frac{7}{9} (x-(4))\\y-5 = \frac{7}{9} (x-4)\\y -5=\frac{7}{9} x-\frac{28}{9}\\y = \frac{7}{9} x-\frac{28}{9} +\frac{45}{9}\\y = \frac{7}{9} x+\frac{17}{9}[/tex]

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 11 centimeters. The factory believes that the length of the bolts exceeds this value and measures the length of 53 bolts. The sample mean bolt length was 11.08 centimeters. The population standard deviation is known to be 0.21 centimeters.
What is the test statistic?
What is the -value?
Does sufficient evidence exist that the length of bolts is actually greater than the mean value at a significance level of 0.01?
Answers
Using the t-distribution, it is found that:
The test statistic is t = 2.77.The p-value is of 0.0039.Since the p-value is less than 0.01, sufficient evidence exists that the length of bolts is actually greater than the mean value at a significance level of 0.01.What are the hypotheses tested?At the null hypotheses, it is tested if the mean is of 11 cm, that is:
[tex]H_0: \mu = 11[/tex]
At the alternative hypotheses, it is tested if the mean is greater than 11 cm, hence:
[tex]H_1: \mu > 11[/tex].
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.For this problem, the values of the parameters are given as follows:
[tex]\overline{x} = 11.08, \mu = 11, s = 0.21, n = 53[/tex]
Hence the value of the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{11.08 - 11}{\frac{0.21}{\sqrt{53}}}[/tex]
t = 2.77.
Using a calculator, with t = 2.77 and 53 - 1 = 52 df, the p-value is of 0.0039.
Since the p-value is less than 0.01, sufficient evidence exists that the length of bolts is actually greater than the mean value at a significance level of 0.01.

Jessie bought 12 cases of soda for the party. If his total bill was $41.40, how much did each case cost?
Answers
Answer:
B. $3.45
Step-by-step explanation:
Number of cases of soda bought = 12
Total bill payed = $41.40
Let x represent the cost of 1 case.
Thus:
12x = $41.40
Divide both sides by 12
12x/12 = 41.40/12
x = 3.45
Cost of each case = x = $3.45
