A car travels 0.75 every minute. Explain how could you use proportional reasoning to find how far the car travels in one hour

1 answer:

7 0

If you know that the car travels 0.75 per minute and that there are 60 minutes are in a hour, you could multiply 0.75 with 60, which gives you an answer of 45.

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2)

MrMuchimi

Answer:

y = -2x + 2

General Formulas and Concepts

Order of Operations: BPEMDAS

<u>Algebra I</u>

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, 4)

y-intercept (0, 2)

<u>Step 2: Find slope </u><em><u>m</u></em>

Substitute: $m=\frac{2-4}{0+1}$
Subtract/Add: $m=\frac{-2}{1}$
Divide: $m=-2$

<u>Step 3: Write linear equation</u>

y = -2x + 2

What is the equation of the line that passes through point 5,8 and has a y-intercept of -2

Bess [88]

Answer:

y = 2x - 2

Step-by-step explanation:

y = mx + b

Sub x = 5, y = 8, and b = -2 into the equation.

8 = 5m - 2

Isolate the m-term and solve for m.

8 + 2 = 5m -2 + 2

10 = 5m

Divide both sides by 5 to isolate m.

m = 2

Sub the parameters (m and b) into the template to get your equation.

y = 2x - 2

The diameter of a pipe is normally distributed, with a mean of 0.8 inch and a variance of 0.0004. What is the probability that t

masya89 [10]

The probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977

<h3>What is probability?</h3>

Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events

<h3>How to determine the probability?</h3>

The given parameters are:

Mean = 0.8

Variance = 0.0004

Calculate Standard deviation using

σ = √σ²

This gives

σ = √0.0004

Evaluate

σ = 0.02

Calculate the z-score at x = 0.84 using

z = (x - $\bar x$ )/σ

This gives

z = (0.84 - 0.8)/0.02

Evaluate

z = 2

The probability is then represented as:

P(x > 0.84) = P(z > 2)

Next, we look up the value of the z table of probabilities

From the z table of probabilities, we have:

P(x > 0.84) = 0.977

Hence, the probability that the diameter of a randomly selected pipe will exceed 0.84 inch is 0.977
