Answer:

3.78

Step-by-step explanation:

378/100 =3.78

100cm=1meter

Answer:

A

Step-by-step explanation:

Hope this helps and I don't really know how to explain.

Answer = B) x = 2, y = 1

As, x + 3y = 5 = 2 + 3(1) = 5, so 2 + 3 = 5

-x + 6y = 4

-2 + 6(1) = 4

-2 + 6 = 4

So, answer = (B)

If he has 1,356 cards and each page he has holds 9 cards, we don't know how many pages he has, so that will be x

1,356/9x -----1,356 (# of cards) divided by 9 (cards each page holds) times x (# of pages)

Divide 9x by 9 to get x by itself -----9x/9=x

Then, what you do to one side you must do to another so divide 1,356 by 9 -----1,356/9=150.667

He needs 150 pages and has .667 left over.

The statement as given is not true. For n = 1, the left side is just the first term, 1, while the right side would be 3(1) - 1 = 2, and 1 ≠ 2.

I think what you meant to write was the equation

1 + 4 + 7 + ... + (3n - 2) = 1/2 n (3n - 1)

which can be easily proved by induction.

For n = 1, we have

1 = 1/2 (1) (3(1) - 1)   →   1 = 1

which is of course true.

Now for the inductive step. Assume the equation holds for n = k, so that

1 + 4 + 7 + ... + (3k - 2) = 1/2 k (3k - 1)

and use this to show it holds for n = k + 1.

We would have

1 + 4 + 7 + ... + (3k - 2) + (3(k + 1) - 2)

which reduces to

1/2 k (3k - 1) + (3k + 1)

3/2 k² + 5/2 k + 1

1/2 (3k² + 5k + 2)

1/2 (k + 1) (3k + 2)

which is precisely what the formula gives on the right side for n = k + 1. QED

Answer:

5 toppings

Step-by-step explanation:

The formula is y=2x+14 with x being the number of toppings and y the total price.

Plug in 25 as y to see how much x would be at that price.

25=2x+14

11=2x

x=5.5

You can't get half of a topping so you would have to round down to 5 toppings.

Answer:

you can order 4 toppings but if you wanted a specific answer, it would be 5.5

Step-by-step explanation:

you have 25, subtract 14, you have 11, divide 11 by 2, you get 5.5 but you cant get half so you have 4 if you round it

Answer:

no solution

Step-by-step explanation:

| −2n | + 10 = −50

Subtract 10 from both sides.

| −2n | = −60

Since an absolute value can never equal a negative number, there is no solution.

Answer: no solution

Answer:

NO SOLUTION

Step-by-step explanation:

Since the left-hand side is always >0 the equation has no solution.

Answer:

110

Step-by-step explanation:

Divide 176 by 8 to get 22 and then multiply 22 by 5 to get 110

Answer:

110

Step-by-step explanation:

176/8 is 22 so there are 22 slices per loaf.

To find the amount of slices in 5 loaves you multiply 22 and 5 to get 110.

Answer:

-.095

Step-by-step explanation:

Answer:

F.) H0:μ=4.55, Ha:μ≠4.55

A.) H0:μ=115, Ha:μ<115

H0:μ=69 , Ha:μ>69

Step-by-step explanation:

The null and alternative hypothesis are used in hypothesis testing.

Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.

1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55

2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)

3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)

Answer:

As the first number is 5, the second will be 7, and the third will be 9.

Step-by-step explanation:

First, let's break down what the information is telling us.

"three consecutive odd integers" means each number is 2 away from each other. So if we were to assign the variable x as the first number, the second would be x + 2 and the third would be x + 4

"sum of the smallest number and twice the middle number" refers to adding the first number and 2 times the second number. So we would write:

x + 2(x + 2)

"is 10 more than the largest number" connects the second part to an equation. This is saying the third number plus 10. So for this, we would write:

(x + 4) + 10

Now we join the information that we have written mathematically into an equation. Since we have an equation, we can solve for the first number, and hence the second and third numbers.

x + 2(x + 2) = (x + 4) + 10

x + 2x + 4 = x + 14

3x + 4 = x + 14

2x = 10

x = 5

As the first number is 5, the second will be 7, and the third will be 9.

The key idea for solving this question is to define a variable and connect it to an equation using the information provided. Try to think about how much information is needed and how many variables need to be defined.

Answer:

NPV= $9,923.56

Step-by-step explanation:

Giving the following information:

Initial cost= -$55,000

Cash flows= $10,000

Cost of capital= 11%

To calculate the net present value, we need to use the following formula:

NPV= -Io + ∑[Cf/(1+i)^n]

First, we need to discount the cash flows:

PV= Cfn / (1+i)^n

Cf1= 10,000/1.11= 9,009.01

Cf2= 10,000/1.11^2= 8,116.22

Cf3= 10,000/1.11^3= 7,311.91

......

Cf12= 10,000/1.11^12= 2,858.41

Total PV= $64,923.56

Now, the NPV:

NPV= -55,000 + 64,923.56

NPV= $9,923.56
