Answer: 2 boxes
Step-by-step explanation: first realize that 7 times 8 is 56 so the manager wants 56 rolls in stock and you only have 40
then subtract 56 - 40 = 16 and this means you need 16 rolls
remember that there is 8 rolls in a box and 16 divided by 8 is 2 so 2 boxes should be ordered

A bag contains only red, green, brown and yellow marbles.
The probabilities of selecting each colour are shown below.
Red = 6x
Green = 2x
Brown = x
Yellow = 4x
Find the probability of selecting a brown marble.
To find the probability of selecting a brown marble, sum the total probability for all marble colors, solve for x, and then use the value of x to get the probability for brown which is 1/13.
Explanation:The question involves calculating the probability of selecting a marble of a certain color from a bag containing marbles of different colors, each with a different probability of being chosen. In this particular problem, we are given that the probabilities of selecting red, green, brown, and yellow marbles are 6x, 2x, x, and 4x, respectively.
Since these are the only colors in the bag, their probabilities must add up to 1 (the total probability), so:
6x + 2x + x + 4x = 1
Summing the multiples of x, we get:
13x = 1
Solving for x gives:
x = 1/13
We can now find the probability of selecting a brown marble, which is just x:
Probability of brown = x = 1/13.
The probability of selecting a brown marble from the bag can be found by dividing the number of brown marbles by the total number of marbles in the bag, which is 1/13.
Explanation:The probability of selecting a brown marble can be found by dividing the number of brown marbles by the total number of marbles in the bag. Since the bag contains four different colors of marbles, the total number of marbles is 6x + 2x + x + 4x = 13x. The number of brown marbles is x. So, the probability of selecting a brown marble is:
P(Brown) = x / (6x + 2x + x + 4x) = x / 13x = 1/13

If the zeros are 1 and -4, what are the factors?
Answer:
(x - 1) and (x + 4)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a, x = b then the factors are
(x - a), (x - b) and the polynomial is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the zeros are x = 1 and x = - 4, thus the factors are
(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)

A.29%
B.30%
C.32%
D.33%
Answer:
answer A
Step-by-step explanation:
The question is about conditional probability. Assuming that the 2% who clicked the link are among the 7% who opened the email, around 29% of the people who opened the email clicked a link. Hence, option A is the correct answer.
Explanation:This question deals with the concept of conditional probability in mathematics, specifically percentages. Assuming that the 2% who clicked the link are among the 7% who opened the email, we want to find out what percent of the 7% clicked the link.
We calculate it like this:
First, remember that 2% of people clicked a link. That's our numerator.Then, remember that 7% of people opened the email. That's our denominator.Divide the numerator by the denominator to get the answer: 2 ÷ 7 = 0.2857 (rounded to four decimal places).So, around 29% (rounding up) of the people who opened the email clicked a link, which makes option A the correct answer.

A silo in the shape of a cylinder is partially filled with corn to cows. The corn fills 50% of the height of the silo. What is the approximate volume of the part of the silo that is filled with corn if the silo is 12ft in diameter and 60ft high?
The volume of the part of silo filled with corn is 3391.2 cubic foot.
Step-by-step explanation:
Diameter of the silo = 12ft.
Radius = 6 ft.
Height = 60ft.
Volume = π(r x r) h
= (3.14) (36) 60
= 6782.4 cubic foot
The corn is 50% filled. So,
Volume of corn filled = (50/100) (6782.4)
= 3391.2 cubic foot
The volume of the part of silo filled with corn is 3391.2 cubic foot.

Step-by-step explanation:
Since the whole length equals 27, we can subtract 3 to get 24. The proportion is a setup for geometric mean. This means cross-multiplying. X x X = X^2, 3 x 24 = 72. Square root both sides to get X by itself. [tex]3\sqrt{8} \\[/tex]. Use Pythagoreans to solve the rest. You are left with the square root of 75, or 5 times the square root of 3.
Austin checks the temperature at 10:00 pm. He notices if the temperature

Solve the system of equations below.

Answer:
(3,-3)
y= -3
x= 3
Step-by-step explanation:
5x+2y=9
2x-3y=15
solve the equation
x=9/5-2/5y
2x-3y=15
substitute the value of x into an equation
2(9/5-2/5y)-3y=15
distribute
18/5-4/5y-3y=15
subtract -4/5 to -3
18/5-19/5y=15
subtract 18/5 from both sides
-19/5=57/5
divide both sides by -19/5
y= -3
substitute the value of y into an equation
x=9/5-2/5(-3)
distribute
x=9/5+6/5

You are riding in a taxi that charges a $10 flat fee, plus an additional $2 per
mile
Let C be the total cost of the ride and M be miles. Write an expression
relating C to M.
Answer:
C= 2M + 10
Step-by-step explanation:
In this equation, we will calculate the total cost. So, we'll start off with "C =" Then, we know tat the charge is $2 per mile so we'll add it and make C = 2M. Then, it states that the flat fee is 10 dollars which makes the equation
C = 2M +10.
Answer:
C = 2M + 10
Step-by-step explanation:
To write this equation, we will use slope-intercept form: y = mx+b
In this problem, C is y and M is x, so: C = mM + b
m is the slope, or the rate of change, and b is the y-intercept.
The y-intercept in this problem is the $10 flat fee.
The rate of change is the additional $2 per mile.
Let's input these values into our equation:
C = 2M + 10
