Solving systems of equations using substitution/eliminationSolving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

y = x + 1

y = 1/2x + 3

Step 2: Solve for x

Substitute in y: x + 1 = 1/2x + 3Subtract 1/2x on both sides: 1/2x + 1 = 3Subtract 1 on both sides: 1/2x = 2Divide both sides by 1/2: x = 4

Step 3: Solve for y

Define original equation: y = x + 1Substitute in x: y = 4 + 1Add: y = 5

Step 4: Graph

We can confirm our answer.

Find the series in A.P whose sum to n terms is n*(n+2)

Answers

Answer:

3, 5, 7, 9, 11, .........

Step-by-step explanation:

Given

[tex]S_{n}[/tex] = n(n + 2) , then

S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3

S₂ = 2(2 + 2) = 2(4) = 8

S₃ = 3(3 + 2) = 3(5) = 15

Thus

a₂ = S₂ - S₁ = 8 - 3 = 5

a₃ = S₃ - S₂ = 15 - 8 = 7

The first 3 terms are 3, 5, 7

This is an AP with common difference d = 2, then

a₄ = a₃ + 2 = 7 + 2 = 9

a₅ = a₄ + 2 = 9 + 2 = 11

and so on

Chocolate chip and peanut butter cookies are randomly chosen from a cookie jar and placed onto a plate. The first plate had four chocolate chip cookies and one peanut butter cookie. A second plate was prepared with 2 chocolate chip cookies and P peanut butter cookies. If the total probability of drawing a chocolate chip cookie from the first plate and then the second plate is 8/25, how many peanut butter cookies, P, are on the second plate? PLEASE HELP THIS IS A FORMATIVE I HAVE TO FINISH THIS TEST AT 12:55, AND IT IS 12:29 RIGHT NOW PLEASE HELP <:(

Answers

Answer:

3 peanut cookies

Step-by-step explanation:

Given that :

Plate 1:

Number of chocolate chip = 4

Number of peanut butter cookies = 1

Probability of drawing chocolate chip cookies from plate 1 :

Probability =( number of required outcome / Total possible outcomes)

P(chocolate chip) = 4 / 5

Plate 2:

Number of chocolate chip = 2

Number of peanut butter cookies = p

P(chocolate chip) = 2 / (2 + p)

Probability of drawing chocolate chip from plate 1 and then plate 2 = 8/ 25

(4/5) * 2/(2+p) = 8/ 25

8 / (10 + 5p) = 8/ 25

8(10 + 5p) = 8 * 25

80 + 40p = 200

40p = 200 - 80

40p = 120

p = 3

Hi! unfortunatly I'm not good at math BUT I would suggest to copy this question and paste on google. Sometimes it gives you the answers. If not then, I'm really sorry! have a good day :)

The probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.

What is probability?

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

The amount on the receipt = {8, 10, 10, 15, 25, 32}

Total outcome = 6

The amounts are grouped as more than $20 and less than $20.

The event is the amount on receipt more than $20 = {25, 32}

Total favourable outcome = 2

Probability = 2/6 = 1/3 or

= 0.33

Thus, the probability of selecting a receipt of more than $20 is 1/3 or 0.33 if the owner of a coffee shop collected receipts from all orders placed during a one-hour period.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

From the line, we can observe that the line is passing through (2, 0) and (0, 0.8).

Then the slope of the line will be

Slope = (0.8 – 0) / (0 – 2)

Slope = 0.4

Then the correct option is A.

The probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.

What is probability?

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that two 12-sided dice are rolled and need to calculate the probability of getting an even number.

Number of favorable outcomes = 6 x 6 = 36

Number of sample = 12 x 12 = 144

The probability of getting an even number will be calculated as:-

Probability = Number of favorable outcomes / Number of sample

Probability = 36 / 144

Probability = 1 / 4

Therefore, the probability that both numbers will be even will be ( 1 / 4 ). The correct option is C.

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Ms. Kraus is 1.75 m tall. When her shadow is 1 m.

Let the shadow of a 265 m tall building be 'x' m.

Therefore by the ratio proportion method.

1.75 : 1 : : 265 : x.

1.75/1 = 265/x.

1.75x = 265.

x = 265/1.75.

x = 151.42 Or 151 m.
