Answer:
T-shirts: 200
Shorts: 50
Step-by-step explanation:
To solve, set up an equation using two variables to represent the number of t-shirts and shorts sold. Let x = t-shirts sold. Let y = shorts sold. 2x + 4y = 600. We know that x will be 4 times greater than y, so we can plug in some guesses that seem reasonable and use the equation to test our theories. My first guess was 50 shorts, which by luck was the correct answer. These problems can be tricky, but setting up an equation can prove to be a great help.

How are rational exponents and radicals related? Summarize how to rewrite a rational power as a radical term using an example of your own.
Answer:
Hi
Step-by-step explanation:
Rational exponent are exponents written in the form of a fraction.
A rational power can be rewritten as a radical in the following way: the bottom of the rational exponent is the root, while the top of the rational exponent is the new exponent on the radical.
Example: X^(1/2)= √X

A movie theater charges $12.00 for adults and $4.50 for children under the age of ten. A group of adults and children went to the movies and spent $75.00 on 10 tickets. How many adults and how many children went to the move?
Answer:
4 Adults and 6 Children went to the movies.
Step-by-step explanation:
(Children) $4.50 x 6 = $27.00
(Adults) $12.00 x 4 = $48.00
$48.00 + $27.00 = $75.00
What is the slope of the line y + 3= 5/7(x + 4)
Answer:
5/7
Step-by-step explanation:
y + 3 = 5/7 (x + 4)
y + 3 = 5/7x + 2 and 6/7
y = 5/7x =1/7
y = mx + b
m = slope

The University of South Texas is interested in determining if there is a difference in the average weight gain between male students (group 2) and female students (group 1) during their freshman year. They take a random sample of 10 male students and 10 female students. Find the confidence interval with 95% confidence. The 95% confidence interval is (2.4, 20.4). A. We are 95% confident that the population mean weight gain for male University of South Texas students is 2.4 more to 20,4 more than female University of South Texas students. B. We are 95% confident that the population mean weight gain for female University of South Texas students is 2.4 more to 20.4 more than male University of South Texas students. C. We are 95% confident that the sample mean weight gain for female University of South Texas students is 2.4 more to 20.4 more than male University of South Texas students. D. We are 95% confident that the sample mean weight gain for male University of South Texas students is 2.4 less to 20.4 more than female University of South Texas students.
Answer: A. We are 95% confident that the population mean weight gain for male University of South Texas students is 2.4 more to 20,4 more than female University of South Texas students.
Step-by-step explanation:
Given a 95% confidence interval of : (2.4, 20.4)
The lower boundary of the interval = 2.4
The upper boundary of the interval = 20.4
Male = group 2, Female = group 1
P2 - P1 is between lower boundary more and upper boundary more ;
Hence
Population mean weight for male is 2.4 more to 20.4 more than female

Answer:
A) -4
Step-by-step explanation:
There are two ways of solving this:
1.) Plugging in the answer choices
Since the equation needs to be equal to or less than 1 (this is due to the less than or equal to sign: ≤)
You will then set the equation: -2x-6 ≤ 1
You will then take each answer choice and plug it into the original equation.
Plug in -4: -2(-4)-6 ≤ 1 this will result in 2 ≤ 1
Plug in -3: -2(-3)-6 ≤ 1 this will result in 0 ≤ 1
Plug in -2: -2(-2)-6 ≤ 1 this will result in -2 ≤ 1
Plug in -1: -2(-1)-6 ≤ 1 this will result in -4≤ 1
The only one that is not true is when you plug in x=-4 into the equation -2x-6. This results in the equation being equal to 2. 2 is not less than 1, making the equation false.
Method 2: Solving the inequality
You can essentially solve for x like a normal inequality.
Instead of solving for -2x-6 = 1, we are doing -2x-6 ≤ 1.
First: Add 6 to the right side
-2x ≤ 1+6 --->>>> 2x ≤ 7
Second: Divid both sides by -2
***Note: When you divivde by a negative when solving an inequality, you must switch the sign. ***
x ≥ -3.5 (hence the sign swtiches from ≤ to ≥ since we divided by a negative value in the equation)
x ≥ -3.5 states that any number greater or equal to -3.5 will work. -4 is less than -3.5, thus it will not satisfy the inequality.
Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car results in 460 miles o. 20 gallons of gas. How far could you drive on 70 gallons of gas.
Answer:
1,610 miles
Step-by-step explanation:
If you do 460/20 you get the gas mileage. The gas mileage is 23. If you do 23*70 you get 1610 miles out of 70 gallons of gas. (Double-check to make sure I'm correct)
Data was collected on the amount of food (in grams) served at two restaurants and the price paid for the meal. The regression line for the data appears on the first plot. The second plot shows the regression analysis conducted when the data is analyzed separately for each of the two restaurants. Which of the following statements best describes the relationship between the variables?
a. The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
b. The correlation between amount of food served and price is strong.
c. The correlation between amount of food served and price is weak within each restaurant, but seems strong when both restaurants are combined.
d. The correlation between amount of food served and price is weak.
Answer:
Option A, The correlation between amount of food served and price is very strong within each restaurant, but seems weak when both restaurants are combined.
Step-by-step explanation:
The graphs for this question are provided in the attachment
Solution -
Graph I - the data points in the graph I do not follow any best fit curve or trendline. This indicates that data is not correlated.
Graph -II In graph II, apart from few outliners majority of data points lie on the best fist curve or the trendline.
Hence, the relation between the two variables i.e food served and price is strong.
Option A fits well for our answer hence it is the correct answer

Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.
9514 1404 393
Answer:
2/5 cups oats per cup water2.5 cups water per cup oatsStep-by-step explanation:
The denominator of the fraction is the unit you want 1 of.
(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)
= (2/5 cups oats)/(1 cup water)
1 cup of water would need 2/5 cups of oats.
__
Obviously, the other ratio is the reciprocal of this.
(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)
1 cup of oats would need 2.5 cups of water
An equation of a line through (-1, 1) which is parallel to the line y = 5x + 1 has slope:
and y-intercept at:
Answer:
The slope is 5 and the y-intercept is at (0, 6)
Step-by-step explanation:
Parallel lines have the same slope, so the slope of the equation is 5. The equation is y = 5x + 6, so the y-intercept is 6.

147 ÷ 7 = 21
Next, multiply that by the denominator (8)
21 x 8 = 168
The answer is 168
Answer:
1/168

Which fraction has a terminating decimal?
- 11/19
- 4/7
- 1/3
- 3/150
==========================================================
Explanation:
With the use of a calculator, we see that,
11/19 = 0.57894736842106...., the decimals eventually repeat; but unfortunately my calculator ran out of room to show the repeating portion4/7 = 0.5714285714285714..., the block "571428" repeats forever1/3 = 0.333333.... the 3s go on forever3/150 = 0.02So 3/150 converts to the terminating decimal 0.02
The word "terminate" means "stop". In the other decimal values, the decimal digits go on forever repeating the patterns mentioned.
----------------------
A non-calculator approach will have us simplify 3/150 into 1/50 after dividing both parts by the GCF 3. Then notice how 50 has the prime factorization of 2*5*5. The fact that the denominator 50 can be factored in terms of only 2's and 5's is enough evidence to conclude that the fraction converts to a terminating decimal.
If the denominator factors into some other primes, other than 2s and 5s, then we don't have a terminating decimal. So that's why 11/19, 4/7 and 1/3 convert to non-terminating decimals.

If this figure is dilated by a scale factor of 3, what would the new coordinates be?
Answer:
J (-3,3), G (0,3), H (4,9), I (3,3)
Step-by-step explanation:
When your dilating a figuring it either gets larger or smaller. Since this is a positive number, and it is not a fraction then the figure is getting larger. Now you multiply each of the original coordinates by 3 to get the dilated coordinates.
