In a freshman high school class of 80 students, 22 students take Consumer Education, 20 students take French, and 4 students take both. Which equation can be used to find the probability, P, that a randomly selected student from this class takes Consumer Education, French, or both?

Answer:

A: 80

Step-by-step explanation:

As we know that the trend line is [tex]y=6.8x+60[/tex], we can plug in x=3 in order to find out the estimated score for 3 hours of studying

[tex]y=6.8x+60\\\\y=6.8(3)+60\\\\y=20.4+60\\\\y=80.4[/tex]

y=80.4 is closest to A: 80

Answer:

Option A, 80

Step-by-step explanation:

Trend line is given by y = 6.8x + 60

where x = number of hours she studied

          y = score

Now we have to calculate the score for a student for studied for 3 hours.

y = 6.8 × 3 + 60

  = 20.4 + 60

  = 80.40

  ≈ 80

Option A will be the answer.

Answer:

The answer is 4 pounds

Step-by-step explanation:

10+14+40=64 oz 64/16 =4

Answer:

4 pounds

Step-by-step explanation:

40 ounces of chicken+ 10 ounces of vegetables+ 14 ounces of rice= 64 ounces of the whole chicken dish.

Now, convert the number of ounces into pounds.

There are 16 ounces in a pound

Or

16 ounces=1 pound

So, divide 16 into 64 to get the number of pounds, which is 4.

The price per ounce of ground beef, when 9 pounds cost $40.32, is $0.28.

Calculating Price per Ounce of Ground Beef

To calculate the price per ounce for ground beef when given the price for 9 pounds, we will first need to know how many ounces are in 9 pounds. Since there are 16 ounces in 1 pound, 9 pounds is equivalent to 144 ounces (9 pounds × 16 ounces/pound).

Next, we divide the total cost of the 9 pounds of ground beef by the total number of ounces to find the price per ounce. The total cost given is $40.32.

Price per ounce = Total cost \/ Total number of ounces

Price per ounce = $40.32 \/ 144 ounces

Price per ounce = $0.28

Therefore, the price per ounce of ground beef is $0.28.

ANSWER

A. 10,000

EXPLANATION

The given rational function is

[tex]f(x) = \frac{1}{x - 2} [/tex]

This function is not defined at x=2.

But as we are picking x-values that are closer and closer to 2, the functional values grows bigger and bigger positively or negatively without bounds.

Therefore a possible value of f(x) as x is close to 2 is 10,000.

The correct answer is A.

Answer:

The base b is 6m

Step-by-step explanation:

The area A of a triangle with base b and height h is given by the formula;

[tex]A=\frac{1}{2}*b*h[/tex]

The area of the triangle is given as 45 while the height h is 15. We substitute these known values into the formula above and solve for the unknown base;

[tex]45=\frac{1}{2}*b*15\\\\90=15*b[/tex]

We finally divide both sides by 15 to solve for b;

b = 90/15 = 6

Therefore, the base of the triangle is 6 m

Answer:

[tex]b = 6\ m[/tex]

Step-by-step explanation:

The area of a triangle is

[tex]A = 0.5b * h[/tex]

Where b is the base of the triangle and ha is the height.

In this case we have a triangle with area

[tex]A = 45\ m ^ 2[/tex]

and with height:

[tex]h = 15\ m[/tex]

So the base of the triangle is:

[tex]45 = 0.5b (15)\\\\b=\frac{45}{15*0.5}\\\\b=6\ m[/tex]

Finally the base of the triangle is b = 6 meters

Answer:

Step-by-step explanation:

the mode of a set of data is the value that occurs most often, in this case it is 44

44 would be the mode of the data.

The mode of the data is the number that occurs the most. It is always best to put the numbers in order from least to greatest so we can see what number appears more than once.

18,27,28,44,44,50,67

When we look at this set of numbers, we can see that 44 appears more than any other number. Therefore, the mode of these numbers is 44.

Answer:

The explicit formula is:

[tex]a_n = 200 +5(n-1)[/tex]

Step-by-step explanation:

Freya increases 5 yards daily to the number of yards she runs.

Note that the increase factor is constant, so this problem can be modeled using an arithmetic sequence.

The explicit formula for an arithmetic sequence is:

[tex]a_n = n_1 + d(n-1)[/tex]

Where:

[tex]a_n[/tex] is the number of yards that Freya runs on the day

[tex]a_1[/tex] is the number of yards that he runs on day 1

d is the increase factor. [tex]d = 5[/tex] yards

n is the number of days

Then as [tex]a_1 = 200[/tex] and [tex]d = 5[/tex], the explicit formula is:

[tex]a_n = 200 +5(n-1)[/tex]

Answer:

The domain of (f*g) (x) is the set of all real numbers; ( -∞, ∞)

Step-by-step explanation:

(f*g) (x) simply means we obtain the product of f(x) and g(x). We are given that;

f(x)=2x

g(x)= 1/x

(f*g) (x) = f(x) * g(x)

(f*g) (x) = 2x * 1/x = 2

This is a horizontal line defined everywhere on the real line. The domain of  (f*g) (x) is thus ( -∞, ∞)

Answer:

All real numbers

Step-by-step explanation:

Given : [tex]f(x)=2x[/tex]

           [tex]g(x)= \frac{1}{x}[/tex]

To Find : the domain of (f*g) (x)

[tex]f(x)=2x[/tex]

[tex]g(x)= \frac{1}{x}[/tex]

[tex](f\cdot g)(x)=2x \times \frac{1}{x}[/tex]

[tex](f\cdot g)(x)=2[/tex]

Answer:

-51, -41, -38, 13, 41, 50

Step-by-step explanation:

The integers ordered from least to greatest are: -51, -41, -38, 13, 41, 50.

To order the integers from least to greatest, one must start by identifying the negative integers and then the positive integers. Among negative integers, the larger the absolute value, the smaller the number. Conversely, for positive integers, the larger the number, the greater it is.

Starting with the negative integers:

-51 is the smallest because it has the largest absolute value among the negative numbers.

-41 is the next smallest negative number.

-38 is the smallest negative number because it has the smallest absolute value among the negatives.

Now, moving on to the positive integers:

13 is the smallest positive number.

41 is the next smallest positive number.

50 is the largest positive number.

Putting it all together:

-51, -41, -38, 13, 41, 50.

Answer:

21π m, or ≈ 65.94 m

Step-by-step explanation:

Remember that π is the ratio between a circle's circumference and its diameter, or, in equation form:

[tex]\pi=\frac{c}{d}[/tex]

where c is the circumference and d is the diameter. If we want to find the circumference, we can just multiply that equation by d on both sides to get

[tex]c=\pi d[/tex]

Here, our d = 21 m, so our circumference would be

[tex]c=21\pi[/tex] m, or approximately 21(3.14) = 65.94 m

Step-by-step explanation:

Let's say x is the number of bowls.  If each bowl needs 3/5 pound of clay, then the total clay needed is 3/5 * x.  We know the total amount is 10 pounds.  Therefore:

10 = 3/5 x

Divide:

x = 10 / (3/5)

To divide by a fraction, we need to multiply by the reciprocal:

x = 10 * (5/3)

x = 50/3

x = 16 ⅔

We can't have part of a bowl, so we must round down.  The potter can make 16 bowls.

2L + 2w = 68 & L = 3w-4

2(3w-4) = 68

6w-8= 68

6w = 60

W= 10

L = 3*10-4

L= 30-4= 26

To make 88,5□1 round down to 88,500, the digit that replaces □ must be less than 5; therefore, the replacements could be :0, :2, or :4.

potential

The given number is '88,5□1' and we want to find the digit that replaces the □ and rounds the number to '88,500' when we round to the nearest hundred. An important point to remember about rounding is that if the digit in the tens place is less than 5, we round down, while if it's 5 or above, we round up. Since we want to round down to 88,500, the digit that replaces □ in the tens place must therefore be less than 5. So, the possible digits could be :0, :2, or :4.

Answer:

7 dollars

____________________________________________________

Step-by-step explanation:

To make solving this equation easier, lets turn the the information we got in the question into an actual equation.

Key information:

4 tickets

$12 popcorn

Spent a TOTAL of $40.

With the information above, we can use it to make an equation.

We would use the equation: y = mx + b

Since our "y" value would represent our total value, our total value is 40, so we would plug 40 into y.

Your equation should look like this:

40 = mx + b

Our "b" value represents our start value, and our start value would be 12 because we started with one $12 popcorn.

Your equation should look like this:

40 = mx + 12

Our "m" value would represent how many tickets we bought, so we would plug in 4 in m.

Our equation would be:

40 = 4x + 12

Now we can solve the equation:

We would move the 12 over to the left side of the equal sign by subtracting, then we would divide by 4.

[tex]40=4x+12\\\\28=4x\\\\7=x[/tex]

We should get ther answer of 7, that means that each ticket cost $7 dollars.

7 dollars should be your FINAL answer.

____________________________________________________

Answer:

One ticket = $7

Step-by-step explanation:

Forming the equation,

→ 4x + 12 = 40

Now the value of x will be,

→ 4x + 12 = 40

→ 4x = 40 - 12

→ x = 28/4

→ [ x = 7 ]

Hence, the value of x is 7.

x^2-5x-24

Step-by-step explanation:

Final answer:

The product of the binomials (x + 3)(x - 8) is simplified using the FOIL method to get x² - 5x - 24. We multiply each term in the first parenthesis by each term in the second and combine like terms.

Explanation:

To multiply and simplify the expression (x + 3)(x - 8), we will use the FOIL method (First, Outer, Inner, Last). This method involves multiplying each term in the first parenthesis by each term in the second parenthesis.

First: x times x = x²

Outer: x times -8 = -8x

Inner: 3 times x = +3x

Last: 3 times -8 = -24

Next, combine like terms (-8x and +3x):

x² - 8x + 3x - 24 = x² - 5x - 24

The simplified form of the given expression is x² - 5x - 24, which corresponds to option C).
