Answer:
[tex]x+y = 80\\325x+50y = 6, 750[/tex]
Step-by-step explanation:
Le x represents the set of new tires
Let y be the set of used tires
If a tire shop counted 80 invoices at the end of the month, then the equal that represents the total amount of invoices counted at the end of the month is:
[tex]x+y = 80 ............ 1[/tex]
If they charge $325 for a set of new tires, the total amount charged for new tires will be:
[tex]325 \times x \\325x[/tex]
If they charge $50 for a set of used tires, the total amount charged for used tires will be:
[tex]50 \times y\\50y[/tex]
If the total dollar amount of the invoices was $6,750, then the expression that models the amount generated on tickets will be:
[tex]325x+50y = 6,750 .............. 2[/tex]
Hence the system of equations represents the situation is:
[tex]x+y = 80\\325x+50y = 6, 750[/tex]
Answer:
x + y = 80
325x = -50y + 6,750

Step-by-step explanation:
[tex]\frac{3}{5} +\frac{1}{4} +\frac{3}{8} =[/tex] Distance Janie walked
First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.
[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]
[tex]\frac{2}{8} +\frac{3}{8} =\frac{5}{8}[/tex]
Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8 and 5/8 by 5/5.
[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]
[tex]\frac{5}{8}*\frac{5}{5}=\frac{25}{40}[/tex]
Now add them.
[tex]\frac{24}{40}+\frac{25}{40}=\frac{49}{40}=1\frac{9}{40}[/tex]miles
You can also convert all to decimals and add.
3/5 = .6
1/4 = .25
3/8 = .375
.6 + .25 + .375 = 1.225
Also 1 [tex]\frac{9}{40}[/tex] = 1.225
whats the answer of 3/4 + 1/4 =
Answer:
1
Step-by-step explanation:
3/4 + 1/4 since they both have a 4 as the denominator you only have to add the top since they made it easy. and since that would be 4/4 your answer would be 1 whole.

For a polynomial P(x), the quotient P(x)/(x-2) has a remainder of 12. What is the value of P(2)? Please explain. Thanks :)
Answer:
12
Step-by-step explanation:
P(x) has infinitely many solutions, but I am going to find the easiest one, which would be a linear equation.
First, notice that x-2 perfectly divides into itself.
Then, if you add 12 to x-2, you will end up with a remainder of 12. Therefore, P(x) would be x-2+12 = x+10.
Now that we know P(x), we can directly plugin 2 to find out P(2):
2+10 = 12
Therefore, P(2) = 12.
The manager of a bakery states in a report that the average value of customer transactions is greater than $13.65. A random sample of 38 transactions was taken, yielding an average of $14.92 with a standard deviation of $5.51. (a) Which hypotheses should be used to show the manager's claim is correct? H0: p = 14.92 vs. Ha: p > 14.92 H0: p = 13.65 vs. Ha: p > 13.65 H0: μ = 13.65 vs. Ha: μ > 13.65 H0: μ = 14.92 vs. Ha: μ > 14.92 (b) Find the test statistic: (Use 4 decimals.) (c) What is the p-value? (Use 4 decimals.) (d) What is the conclusion of the hypothesis test, for α = 0.05? --- the value $13.65. There is --- evidence the mean transaction value is greater than $13.65. (e) Regardless of your conclusion above, what is the meaning of a Type II error in this context? you conclude the average transaction value is greater than $13.65, in reality the average transaction value is greater than $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is greater than $13.65, in reality the average transaction value is equal to $13.65. You conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Answer:
A) Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) t = 1.42
C) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
D) type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.
Step-by-step explanation:
We are given;
Population mean; μ = $13.65
Sample mean; x¯ = $14.92
Sample standard deviation; s = $5.51
Sample size; n = 38
DF = n - 1 = 38 - 1 = 37
Significance level; α = 0.05
A) The hypotheses is defined below;
Null Hypothesis; H0: μ = 13.65
Alternative hypothesis; Ha: μ > 13.65
B) Since we are given sample standard deviation, we will use formula for t-value. Formula for the test statistic is;
t = (x¯ - μ)/(s/√n)
t = (14.92 - 13.65)/(5.51/√38)
t = 1.42
C) From online p-value from t-score calculator attached, using; t = 1.42, α = 0.05, DF = 37, one tail, we have;
P-value = 0.08199
D) The p-value is greater than the significance level of 0.05. Thus, we fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean transaction value is greater than $13.65.
E) A type II error simply means accepting a null hypothesis that is not true.
Now, in this case what it will mean is to accept the null hypothesis.
Thus, type II error will be to conclude the average transaction value is equal to $13.65, in reality the average transaction value is greater than $13.65.

None of the options are correct because no table shows the 1 gallon per minute.
Given that,
To determine which of the table shows the rate of 1 gallon per minute.
Rate of change is defined as the change in value with rest to the time is called rate of change.
