Sorry if late I need points

The sums 5 + (–2), –3 + 4, and –2 + 4 are positive option (B), (C), and (E) are correct.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

It is given that:

A.–5 + (–2)

= -5 + (-2)

= -5 - 2

= -7 (negative)

B. 5 + (–2)

= 5 - 2

= 3 (positive)

C. –3 + 4

= -3 + 4

= 1 (positive)

D. 0 + (–3)

= -3 (negative)

E. –2 + 4

= -2 + 4

= 2 (positive)

Thus, the sums 5 + (–2), –3 + 4, and –2 + 4 are positive option (B), (C), and (E) are correct.

Answer:

Approximately 14.4 inches

Step-by-step explanation:

A 16-inch laptop means that a diagonal across the screen is 16 inches.

Imagine that the laptop is a triangle, with 2 sides: the height and the width of screen, and a hypotenuse, the diagonal across the screen (see attached image).

Here, we can use the Pythagorean theorem to find the width.

The relationship is the following

[tex]diagonal^2 = height^2 + width^2[/tex]

We can rearrange this to find the width of the screen:

[tex]diagonal^2 = height^2 + width^2\\diagonal^2 -height^2 = width^2\\width^2 = diagonal^2 -height^2\\width = \sqrt{diagonal^2 - height^2}[/tex]

Let's put in our values for the diagonal and the height:

Diagonal = 16

Height = 7

[tex]width = \sqrt{16^2 - 7^2}\\ width = \sqrt{256 - 49} \\width = \sqrt{207}\\width = 14.3874946[/tex]

As we can see, the width of our laptop is around 14.4 inches.

Answer: approximately 14.4 inches

The width of the laptop screen is x = 14.3inches.

Given that,

A 16 inch laptop has a screen that is 7 inches tall.

We have to determine,

How wide is the screen.

According to the question,

 Diagonal length of the laptop = 16 inches

Length of the laptop = 7 inches

Width of the laptop = x inches

By using Pythagoras theorem,

[tex](Diagonal)^2 = (length)^{2} +( width)^{2}\\\\(16)^2 = (7)^2 + x^{2} \\\\x^{2} = 256 - 49\\\\x^{2} = 207\\\\x = \sqrt{207}\\\\x = 14.38 \ inches[/tex]

Hence, The width of the laptop screen is x = 14.3inches.

Answer:

x=3 LA=12

Step-by-step explanation:

PL plus PA is equivalent to LA. So, (x+4)+(2x-1)=5x-3, which can be rewritten as 3x+3=5x-3. Now we can add 3 to both sides to get 3x+6=5x and subtract 3x from both sides to get 6=2x. Now we divide by 2 on both sides to get x, which is 3, and we can plug that into the equation for LA. So we get 5(3)-2=LA. LA equals 12.

Steps to solve (x+4)+(2x-1)=5x-3:

1: (x+4)+(2x-1)=5x-3

2: 3x+3=5x-3 Rewrite equation

3: 3x+6=5x Add 3 to both sides

4: 6=2x Subtract 3x from both sides

5: 3=x Divide by 2 on both sides

The value of x is 3 and the value of LA is 12.

PL = x + 4,

PA = 2x − 1,

LA = 5x − 3.

Since P is between L and A, then the equation to get x will be:

PL + PA = LA

(x + 4) + (2x - 1) = (5x - 3)

Open the bracket

x + 4 + 2x - 1 = 5x - 3

Collect like terms

3x + 3 = 5x - 3

5x - 3x = 3 + 3

2x = 6

x = 6/2

x = 3

LA = 5x - 3

LA = 5(3) - 3

LA = 15 - 3.

LA = 12

Answer:

(a) less than 10 minutes

= 0.5

(b) between 5 and 10 minutes

= 0.5

Step-by-step explanation:

We solve the above question using z score formula. We given a random number of samples, z score formula :

z-score is z = (x-μ)/ Standard error where

x is the raw score

μ is the population mean

Standard error : σ/√n

σ is the population standard deviation

n = number of samples

(a) less than 10 minutes

x = 10 μ = 10, σ = 2 n = 50

z = 10 - 10/2/√50

z = 0 / 0.2828427125

z = 0

Using the z table to find the probability

P(z ≤ 0) = P(z < 0) = P(x = 10)

= 0.5

Therefore, the probability that the average waiting time waiting in line for this sample is less than 10 minutes = 0.5

(b) between 5 and 10 minutes

i) For 5 minutes

x = 5 μ = 10, σ = 2 n = 50

z = 5 - 10/2/√50

z = -5 / 0.2828427125

= -17.67767

P-value from Z-Table:

P(x<5) = 0

Using the z table to find the probability

P(z ≤ 0) = P(z = -17.67767) = P(x = 5)

= 0

ii) For 10 minutes

x = 10 μ = 10, σ = 2 n = 50

z = 10 - 10/2/√50

z = 0 / 0.2828427125

z = 0

Using the z table to find the probability

P(z ≤ 0) = P(z < 0) = P(x = 10)

= 0.5

Hence, the probability that the average waiting time waiting in line for this sample is between 5 and 10 minutes is

P(x = 10) - P(x = 5)

= 0.5 - 0

= 0.5

Step-by-step explanation:

To answer this question you would write down 105+165 you'll get 260 then to know how much wilma will have to pay you would take the amount wilma pays monthly which is 395 and the answer you got from 105+165 which is 260 and add 395-260 so, 395-260=135

Answer: Wilma should also consider the expenses of fuel, maintenance, and repairs. These are variable expenses and can vary greatly from month to month. To make sure that she can afford a new car, she needs to include these variable expenses in her car budget calculations. If Wilma can’t afford these expenses, she may need to choose a different car with a lower monthly payment or one that requires fewer maintenance costs.

Answer:

30 and 60 degrees

Step-by-step explanation:

30 and 60 are complementary angles. 60 is two times the measure of its complementary angle, or 30. 60+30=90.

Complementary angles are angles that add up to 90 degrees.

Angle one = x

Angle two = 2x

2x + x = 90 degrees

Combine like terms.

3x = 90 degrees.

Divide both sides by 3

x = 30

Angle one = x = 30 degrees

Angle two = 2x = 2(30) = 60 degrees.
