Find the sum for the equation (2m + 2y + 5) and (1m + 7y - 10) where m=2 and y=-1
a. Remember! You need to plug in the values for m and y with the numbers provided.

Answers

Answer 1
Alright let’s start with (2m+2y+5). If m=2 and y=-1, then you can plug in (2(2)+2(-1)+5). 2(2) is 4, so 4+2(-1)+5. 2(-1) is -2, so now 4+-2+5. And addition sign and a negative sigh cancel to make 4-2+5.

Answer: 7

Now (1m+7y-10), again we plug in m=2 and y=-1. (1(2)+7(-1)-10). 1(2) is 2. 7(-1) is -7. So now (2+-7-10), and the addition sign and negative sign make it (2-7-10). 2-7 is -5 minus 10.

Answer: -15

Have a good day mate.
Answer 2

Answer:

-8

Step-by-step explanation:

2(2) + 2(-1) + 5 + 1(2) + 7(-1) - 10

(4 + -2 + 5) + (2 + -7 - 10)

7 + -15

= -8

The mean housing price for an area is $135,000 with a standard of $45,000 but is not normally distributed. According to the Central Limit Theorem what would we need to make sure is true about our sample in order to use normal distribution

Answers

Answer:

A sample size greater than 30

Step-by-step explanation: The central limit theorem proffers the conditions necessary to obtain a normal or bell shaped distribution. It defines normal distribution in terms of mean, standard deviation and sample size. The sample size is a very important factor in determining the shape of a distribution.

Thus with a population having mean and standard deviation stated, in other to make use of or assume normal distribution, the sample size must be large. According tho the central limit theorem, a size of greater than 30 is deemed to be large enough. As the Same size increases, the sample mean converges to the value of the population mean.

You have two pieces of rope. One piece is of rope is 98 feet and the other is 56 feet. You need to cut the rope into equal lengths with non left over. What is the greatest possible lenth you can cut the rope so all peices will be the same

Answers

Answer:

14 feet

Step-by-step explanation:

We solve the above question by using the Greatest Common Factor method

We find the factors of 56 and 98

The factors of 56 are: 1, 2, 4, 7, 8, 14, 28, 56

The factors of 98 are: 1, 2, 7, 14, 49, 98

Then the greatest common factor is 14.

Therefore, the greatest possible length you can cut the rope so all pieces will be the same is 14 feet

zoe has a total of 16 coins. some of her coins are dimes and some are nickels. The combined value of her nickels and dimes is 1.35. How many nickels and dimes does she have?

Answers

Given:

In 16 coins some coins are dimes and some are nickels.

The combined value of her nickels and dimes is 1.35.

To find:

The number of nickels and dimes.

Solution:

We have,

Number of total coins = 16

Combined value = $1.35

Let x be the number of nickels and y be the number of dimes.

Total coins: [tex]x+y=16[/tex]              ...(i)

We know that,

1 nickel = $0.05

1 dime = $0.10

Combined value: [tex]0.05x+0.10y=1.35[/tex]          ...(ii)

From (i), we get

[tex]y=16-x[/tex]           ...(iii)

Putting this in (ii), we get

[tex]0.05x+0.10(16-x)=1.35[/tex]

[tex]0.05x+1.60-0.10x=1.35[/tex]

[tex]-0.05x=1.35-1.60[/tex]

[tex]-0.05x=-0.25[/tex]

Divide both sides by -0.05.

[tex]x=\dfrac{-0.25}{-0.05}[/tex]

[tex]x=5[/tex]

Putting x=5 in (ii), we get

[tex]y=16-5[/tex]

[tex]y=11[/tex]

Therefore, the number of nickels is 5 and the number of dimes is 11.

2 X 5 + 1 = 11/5

11/5 X 2/1 = 22/5

1 3/4

1 X 4 + 3 = 7/4

7/4 X 2/1 = 14/4

22/5 + 14/4

5 X 4 = 20

4 X 22 = 88

5 X 14 = 70

88/20 + 70/20 = 158/20

20 goes into 158 7 times with 18 left over
