Given system of linear equations are ,

And we need to find the Solution of the linear equation . So let's Firstly number the equations .

[tex]\large{\red{\frak{ Given}}}\begin{cases} \sf x + y = 2\qquad ..........(i) \\\\\sf -3x + y = 2 \qquad ..........(ii) \\\end{cases}[/tex]

→ Multiplying equⁿ (i) by 3 ,

=> 3 ( x + y ) = 2*3

=> 3x + 3y = 6

→ Adding the two equations ,

=> 3x + 3y -3y + y = 6 + 2

=> 4y = 8

=> y = 8/4

=> y = 2

→ Put y = 2 in (i) ,

=> x + y = 2

=> x + 2 = 2

=> x = 2- 2

=> x = 0

Answer:

Each number matches up below. The left side is x, and the right is y.

1 ⇒ 192

2 ⇒ 384

4 ⇒ 768

6 ⇒ 1152

10 ⇒ 1920

Step-by-step explanation:

We know in 1 serving, there is 192 calories. Following this, to find the calories for 2 servings, we multiply 192 by 2.

192*2 = 384

When we know the calories but not the serving, you divide the calories by 192

768/192 = 4

Answer:

a)

P(X = 0) = 0.2840

P(X = 1) = 0.4201

P(X = 2) = 0.2331

P(X = 3) = 0.0575

P(X = 4) = 0.0053

c) The most likely value for X is 1.

d) 0.2959 = 29.59% probability that at least two of the four selected have earthquake insurance.

Step-by-step explanation:

For each homeowner, there are only two possible outcomes. Either they are insured against earthquake damage, or they are not. Homeowners are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

27% of all homeowners are insured against earthquake damage.

This means that [tex]p = 0.27[/tex]

Four homeowners are to be selected at random.

This means that [tex]n = 4[/tex]

(a) Find the probability distribution of X.

This is the probability of each outcome. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{4,0}.(0.27)^{0}.(0.73)^{4} = 0.2840[/tex]

[tex]P(X = 1) = C_{4,1}.(0.27)^{1}.(0.73)^{3} = 0.4201[/tex]

[tex]P(X = 2) = C_{4,2}.(0.27)^{2}.(0.73)^{2} = 0.2331[/tex]

[tex]P(X = 3) = C_{4,3}.(0.27)^{3}.(0.73)^{1} = 0.0575[/tex]

[tex]P(X = 4) = C_{4,4}.(0.27)^{4}.(0.73)^{0} = 0.0053[/tex]

So the probability distribution is

P(X = 0) = 0.2840

P(X = 1) = 0.4201

P(X = 2) = 0.2331

P(X = 3) = 0.0575

P(X = 4) = 0.0053

(c) What is the most likely value for X?

P(X = 1) has the highest probability, so X = 1 is the most likely value.

(d) What is the probability that at least two of the four selected have earthquake insurance?

[tex]P(X \geq 2) = P(X = 2) + P(X = 3) + P(X = 4) = 0.2331 + 0.0575 + 0.0053 = 0.2959[/tex]

0.2959 = 29.59% probability that at least two of the four selected have earthquake insurance.

Step-by-step explanation:

Nicholas has purchased 1.8 pounds of pixie sticks.

Jane has purchased 3.0 pounds of Jolly ranchers.

Step-by-step explanation:

Cost of 1 pounds of pixie sticks = $4.50

Let the number of pixie sticks = x

Total  money spend on x pounds of pixie sticks = $8.10

Nicholas has purchased 1.8 pounds of pixie sticks.

Cost of 1 pounds of Jolly ranchers = $3.25

Let the number of Jolly ranchers = y

Total  money spend on y pounds of Jolly ranchers = $9.75

Jane has purchased 3.0 pounds of Jolly ranchers.

Answer:

60 tiles

Step-by-step explanation:

Make equations equal,

.99x + 24 = 1.39x

Move all terms containing  x  to the left side of the equation & subtact 24

-.4x = -24

Divide

x = 60

Double check:

.99(60) + 24 = 83.4

1.39(60) = 83.4

Answer:

[tex]x = 6[/tex]

Carl is correct

Step-by-step explanation:

Given

[tex]\frac{6}{3} = \frac{12}{x}[/tex]

See attachment

Required

Is Carl correct?

Using the side spotter theorem, the proportion is:

[tex]\frac{AB}{BC} = \frac{AE}{ED}[/tex]

This gives:

[tex]\frac{6}{3} = \frac{12}{x}[/tex]

This proportion is equivalent to Carl's.

Hence, Carl is correct.

Solving further: Cross Multiply

[tex]6 * x = 12 * 3[/tex]

[tex]6 * x = 36[/tex]

Make x the subject

[tex]x = \frac{36}{6}[/tex]

[tex]x = 6[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

In order to find that, we simply do:

(100+25)% = 125%

100% = 12 ounces

125% = ?

12*125/100 = 9 ounces

Add it up to the original amount:

12+9 = 21 ounces

Answer:

10.7%

Step-by-step explanation:

A graphing calculator or spreadsheet program can plot these points for you. It's probably no more work to actually plot the points yourself on the given graphs than it is to type them into a program.

As you know, the x-coordinate is the horizontal distance from the y-axis. Positive is to the right.

The y-coordinate is the vertical distance from the x-axis. Positive is up.

Answer:

17.4

Step-by-step explanation:

3 + 4 + 5 + 7 + 10 + 12 + 15)/7 = 8

(3^2 + 4^2 + 5^2 + 7^2 + 10^2 + 12^2 + 15^2)/7 - 8^2 = 17.14285714

17.14285714 = 17.4

Answer:

a) 26.79%, b) 50.42% and c) 22.79%

Step-by-step explanation:

a. What is the probability that both Dave and Mike will show up?

As decisions of showing up can be assumed to be independent, the probability will be given by

(1-0.53)(1-0.43)=(0.47)(0.57)=0.2679=26.79%

b. What is the probability that at least one of them will show up?

There are two possibilities for this to happen:

Dave shows up but Mike does not. The probability of Dave to show up is (1-0.53)=0.47 and the probability that Mike does not is 0.43. Then, as these events are independent, the probability for both of them to happen is (0.47)(0.43)=0.2021=20.21%

Mike shows up but Dave does not. The probability of Mike to show up is (1-0.43)=0.57 and the probability that Mike does not is 0.53. Then, as these events are independent, the probability for both of them to happen is (0.57)(0.53)=0.3021=30.21%

Therefore, the probability that at least one of them will show up? is 20.21%+30.21%=50.42%.

c. What is the probability that neither Dave nor Mike will show up?

As decisions of showing up can be assumed to be independent, the probability will be given by

(0.53)(0.43)=0.2279=22.79%
