Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

Answers

Answer:

a. 12

b. 1/2

Step-by-step explanation:

Given a meal has 3 choices of meat, 2 choices of fruit, and 2 choices of dessert, you want to know the number of possible meals, and the probability of a meal with no cookie for dessert.

a. Possibilities

As the tree diagram shows, the number of possible meals is ...

(possible meats)×(possible fruits)×(possible desserts)

= 3×2×2 = 12

There are 12 possible lunch options.

b. Cookies

Half the possible dessert choices have no cookie. That is the probability that a lunch will have no cookie:

P(no cookie) = 1/2

__

Additional comment

The bottom line of the tree diagram has 6 Cs and 6 Ms. That is, 6 of the 12 options for meals have no cookie.

Using a proportion, how can we find 12% of 125? Please show your proportion set up and all work. HELP ME ASAPPPPPPPPP THE CORRECT ANWSER GETS A BRAINLIST I HAVE 3MINS SOMEONE PLEASE!!!!!

Answers

Answer: 15

Step-by-step explanation:

Write 12% as a fraction: 12/100

Since, finding the fraction of a number is same as multiplying the fraction with the number, we have: 12/100 of 125.

12/100 × 125

If you are using a calculator, enter 12÷100×125 which will give you 15 as the answer.

What is the length of b

What is the length of b

Answers

Answer:

b = 24

Step-by-step explanation:

Concepts

The Pythagorean Theorem states that the sum of the squares of the two other sides on a right triangle is equal to hypotenuse (longest side) squared. It can be represented by the equation \(a^2+b^2=c^2\). We can also use this formula to solve for the other two legs in the right triangle.

Application

In this case, we're asked to find the length of b in the right triangle, given c as 26 and a as 10. Now, we just apply the formula and solve for b.

Solution

Step 1: Set up equation and simplify.

\(10^2+b^2=26^2\) \(100+b^2=676\)

Step 2: Subtract 100 from both sides.

\(100+b^2-100=676-100\) \(b^2=576\)

Step 3: Take square root of both sides.

\(\sqrt{b^2} =\sqrt{576}\) \(b=24\)

Therefore, b = 24.

Use the substitution method to solve the following system of equations.

Use the substitution method to solve the following system of equations.

Answers

Answer:

(x,y)=(2,0)

Step-by-step explanation:

Use the first equation to find x. add 1/6 y on both sides, then multiply by 6/5 to get x by itself.

you will get x=2+1/5y

Now you substitute the x value into the second equation

1/2(2+1/5y)+3/4y=1

Distribute the 1/2 to get

1+1/10y+3/4y=1

The only possible value for y is 0.

Now you know y = 0.

Now substitute 0 in for the y in the x value

x = 2+1/5y

x=2+0

x=2

Therefore your answer is (2,0) or x=2 y=0

(x,y)= (2,0) because that’s how you do it

Answers

Answer:Median; because the data is not symmetric and there are outliers.

Step-by-step explanation:We know that a median is a central tendency of a data and it best represents the given data set.

From the given information we see that the data is skewed to the right since most of the data points takes the higher value and the data is not symmetric as it is skewed.
