Answer:

When m = 16 and n = 4, m - 2 * n + 2 = 10.

Step-by-step explanation:

m - 2 * n + 2

Substitute values given

m = 16

n = 4

16 - 2 * 4 + 2

Multiply -2 and 4.

16 - 8 + 2

Subtract 8 from 16.

8 + 2

Add 8 and 2.

10.

If the original expression had parenthesis, please let me know as this answer would need to be edited.

12 kittens & 8 puppies are in the park. what is the largest number of groups they can be split into and have the same number

IRINA_888 [86]

2 groups with 2 puppies and 3 kittens in each group

Equation for kittens:

$12 \div 2 = 6 \div 2 = 3$

Equation for puppies:

$2 \div 8 = 4 \div 2 = 2$

the division has been done two times so it means the largest number of groups it can be split into are two

Alicia is making cupcakes for a party she is having and wants to make sure everyone gets at least one cupcake. The recipe calls

Liula [17]

$\frac{84}{21}=4$

Therefore you need 4 batches of cupcakes if you want every person to get one cupcake.

This means you multiply the amount of salt per batch by the number of batches, to get the total amount of salt you need.
Each batch contains 1 teaspoon of salt for 21 cupcakes. Multiply: $4\text{ batches of cupcakes}\times1\text{ teaspoon of salt}=4\text{ teaspoons salt}$ for the whole thing.

Answer:

The probability of the spinner landing on an even number or a multiple of 3 is 0.6667 .

The probability of the spinner landing on an odd number or a number between 4 and 15 (both numbers excluded) is 0.7778 .

Step-by-step explanation:

Be the events

A = even number

B = Multiple of 3

C = Odd Number

D = Number between 4 and 15, both numbers excluded

The sets are as follows:

A = {2,4,6,8,10,12,14,16,18}

B = {3,6,9,12,15,18}

C = {1,3,5,7,9,11,13,15,17}

D = {5,6,7,8,9,10,11,12,13,14}

To calculate the probability that the roulette lands in an even number or in a multiple of 3, we make the union of A and B:

A U B = {2,3,4,6,8,9,10,12,14,15,16,18} = 12 numbers of 18

P (A U B) = 12/18 = 2/3 = 0.6667

To calculate the probability that roulette lands on an odd number or a number between 4 and 15 (both numbers excluded), we make the union of C and D:

C U D = {1,3,5,6,7,8,9,10,11,12,13,14,15,17} = 14 numbers of 18

P (C U D) = 14/18 = 7/9 = 0.7778

The first answer is 0.6667

The second answer is 0.7778

Hope this helps!
