Answer:
He bought 12 books.
Step-by-step explanation:
Here is your equation: 6 b+3=75
Step 1- Subtract 3 from both sides: 6 b+3-3=75-3
6 b=72
Step 2- Divide by 6: 6 b/6=72/6
b = 12 books in total.

What is the probability that a jury chosen at random includes at least 10 men? Calculate P(at least 10 men).
Answer:
.00552
Step-by-step explanation:
To find the probability of choosing a jury with at least 10 men, add the individual probabilities of choosing juries with 10 men, 11 men, and 12 men and then add the individual probabilities (because each case is exclusive).
Adding the three probabilities, the probability of a jury with at least 10 men is:
P(at least 10 men)
P(10 men) + P(11 men) + P(12 men)
= 0.005 + 0.0005 + 0.00004
= 0.00552

Answer:
See Below.
Step-by-step explanation:
Paragraph Proof:
We are given that ∠1 ≅ ∠4. ∠1 and ∠4 are alternate exterior angles. Since they are congruent, by the Alternate Exterior Angles Converse, the two lines being cut by the transversal must be parallel. Then by the Alternate Interior Angles Theorem, ∠3 ≅ ∠2.
2-Column Proof
Statements Reasons:
1) [tex]\angle 1\cong \angle 4[/tex] Given
2) [tex]\text{The two lines are parallel}[/tex] Alternate Exterior Angles Converse
3) [tex]\angle 3\cong \angle 2[/tex] Alternate Interior Angles Theorem

if 26 articles cost $214.50 what amount does what amount does one article called what is the cost of 15 articles
Answer: one costs 8.25 and 15 costs 123.75
Step-by-step explanation: 214.5/26 = 8.25 x 15 = 123.75
Answer:
15 articles cost $123.75
Step-by-step explanation:
In order to find the answer, you first need to divide $214.50 by 26 which is $8.25 for per article, and multiply it by 15 to find how much it cost for 15 articles which is $123.75
Write the quadratic equation whose roots are −6 and 4, and whose leading coefficient is 4. (Use the letter x to represent the variable.)
Answer:
4(x-4)(x+6)
Standard form: 4x^2+8x-96
Step-by-step explanation:
Since the roots are set to be -6 and 4, we need to find 2 linear equations that are equal to 0 when x is at -6 and when x is at 4, and multiply them together. That would look like this:
(x-4)(x+6)
Notice how if I plug in 4 or -6 for x, the whole thing is going to be 0.
Now, if we were to factor this, the leading coefficient would be 1. Since we want to change the leading coefficient while still preserving our roots, we can just multiply the whole polynomial by 4:
4(x-4)(x+6)
Notice if I still plug in 4 or -6 for x, the whole thing is going to be 0.
In standard form, the polynomial would be 4x^2+8x-96.

Alisa bought 3 shirts for $29 each and then spent $15 on lunch. She has $31 left. How much money did she have before?
Answer:
$133
Step-by-step explanation:
Let x = amount of money she had before she spent any money.
x - 29 - 29 - 29 - 15 = 31
x - 102 = 31
x = 133
Answer: She had $133.
Answer:
she had 133$
Step-by-step explanation:
Multiply 29$ by the amount of shirts and get 87$
then add 31$, the 15$ she spent on lunch, and add the 87$ and get 133$.

You can solve this equation by putting it into a calculator.
The answer is positive because there's two negative numbers (they cancel out). If you have an even number of negatives, your answer should be positive. If you have an odd number of negatives, your answer should be negative.

Actually Welcome to the Concept of the Mathematics, this is called as function inside another function, just we have replace the condition of x here,
1)g(f(4)) = here, f(4) = 4-7= -3
so now, g(-3) = (-3)^2 =9
g(f(4)) = 9
2) f(g(4)) = 16-7 = 9
f(g(4))= 9
3) g(f(-1)) = 64
4) f(g(-1)) = -6
done.
The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by latex of the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?
Complete question :
The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?
Answer:
-6°F
Step-by-step explanation:
Temperature at 5am (t1) = - 6°F
Temperature at 3pm (t2) = 36°F
Change in temperature, between 5am and 3pm:
(t2 - t1) = (36 - (-6)) = (36 + 6) = 42°F
Hence, temperature at 8:00 pm:
High temperature - change in temperature between (5am - 3pm)
36°F - 42°F = - 6°F

Step-by-step explanation:
Hector wants to tile his rectangular shed floor with rubber tiles. He found a company that will cut custom tiles up to 60 inches by 60 inches. The length of his shed floor is 240 inches, and the width is 144 inches. A-what is the side length of the largest square tile Hector can use to tile his shed floor so that there are no gaps or overlaps and the entire floor is covered? B-How many floor tiles will Hector need to cover his shed floor? HURRY PLEASE. ANSWER BOTH!!
Answer:
A- The side length of the largest square tile Hector can use to tile his shed floor so that there are no gaps or overlaps is 48 inches
B- The number of square tiles Hector will need is 15 tiles
Step-by-step explanation:
A- The given parameters are;
The size of the tiles cut by the company he found = 60 inches × 60 inches
The length of his shed floor = 240 inches
The width of his shed floor = 144 inches
The side length of the largest square tile is given as the highest common factor, HCF of 240 and 144 given as follows;
144/240 = 3/5
Therefore, we have the highest common factor of 144 and 240 = 144/3 = 48
Therefore, the side length of the largest square tile Hector can use to tile his shed floor so that there are no gaps or overlaps = 48 inches
B- The area of his shed floor = 240 inches × 144 inches = 34560 in.²
The area of one square tile = 48 inches × 48 inches = 2,304 in.²
The number of square tiles, n, Hector will need is given as follows;
The number of square tiles Hector will need = (The area of his shed floor)/(The area of one square tile)
The number of square tiles Hector will need = n =34560 in.²/(2,304 in.²) = 15
The number of square tiles Hector will need = 15 tiles.
Solve the inequality: -7y - 3x < 21
Answer:
x> -7/3y -7
Step-by-step explanation: -7y-3x<21
Step 1: Add 7y to both sides.
−3x−7y+7y<21+7y
−3x<7y+21
Step 2: Divide both sides by -3.
-3x/-3 < 7y+21/-3
x>-7/3y -7

Which of the following is true about the function above? - Apex
Answer:
The answer is B, The domain is (-4, infinite) and it's range is (0, infinite)
Step-by-step explanation:
If we graph this equation, we can see that x=-4 is the ascending point on the graph, infinitely continuing upwards, giving us -4, infinite. The range, however is found with infinitely continuing off the graph to the right, making it a positive infinitely for the y value as it is NOT a steady straight line.

The data set represents the responses, in degrees Fahrenheit, collected to answer the question "How hot is the sidewalk during the school day?". 92, 95, 95, 95, 98, 100, 100, 100, 103, 105, 105, 111, 112, 115, 115, 116, 117, 117, 118, 119, 119, 119, 119, 119, 119 a. Create a dot plot to represent the distribution of the data. b. Create a histogram to represent the distribution of the data. c. Which display gives you a better overall understanding of the data? Explain your reasoning.
Answer:
a) Please find attached the created dot plot
b) Please find attached the created histogram
c) The dot plot
Step-by-step explanation:
The given data on the responses to the question on "How hot is the side walk, during the school day", is presented as follows;
92, 95, 95, 95, 98, 100, 100, 100, 103, 105, 105, 111, 112, 115, 115, 116, 117, 117, 118, 119, 119, 119, 119, 119, 119
Given that manner of construction of the dot plot and the histogram, the display of the results are similar, however, due to the low frequencies of the data, the dot plot provides a view that allows quicker and clearer understanding of the data

Mr. Khans is buying staplers for his office. Each stapler costs $16.99. what is the independant variable
Answer:
number of staplers
Step-by-step explanation:
In this question, there are two variables: the cost and the number of staplers. The cost depends on the number of staplers, so cost is the dependent variable. This means the number of staplers is the independent variable.
