Which is the equation of a line with a slope of -1/3 and a yintercept at (0, 1)?

1 answer:

4 0

Y = mx + b

m is -1/3

plug in your given values for x and y to find b

1 = (-1/3)(0) + b
1 = 0 + b
b = 1

make equation
y= (-1/3)x + 1

What are the coordinates of B and how is that the answer ?

Trava [24]

Step-by-step explanation:

Point A = (-1, -3).

Midway of AB = (-3, 2).

Let Point B = (x, y).

Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).

=> (2, -5) = (-3-x, 2-y).

We have -3 - x = 2 and 2 - y = -5.

So x = -5 and y = 7.

Hence, point B = (-5, 7).

0.5x-7= 0.3 solve the equation<br><br><br><br><br>

Lena [83]

Answer:

<h3> $\boxed{ \bold{ \boxed{ \sf{x = 14.6}}}}$ </h3>

Step-by-step explanation:

$\sf{0.5x - 7 = 0.3}$

Move 7 to right hand side and change it's sign

⇒ $\sf{0.5x = 0.3 + 7}$

Add the numbers

⇒ $\sf{0.5x = 7.3}$

Divide both sides of the equation by 0.5

⇒ $\sf{ \frac{0.5x}{0.5} = \frac{7.3}{0.5} }$

Calculate

⇒ $\sf{x = 14.6}$

Hope I helped!

Best regards!!

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 6.9 years, and standard deviation of

Lostsunrise [7]

ANSWER

0.9738 or 97.38%

EXPLANATION

Given:

$\begin{gathered} mean(\mu)=6.9 \\ Standard\text{ }Deviation(\sigma)=1.6 \end{gathered}$

Desired Outcome:

Probability that it will last 10 years

z-score for the sample:

$\begin{gathered} z-score=\frac{X-\mu}{\sigma} \\ z-score=\frac{10-6.9}{1.6} \\ z-score=1.9376 \end{gathered}$

p-value

For the z-score of 1.9376, the p-value is 0.9738 or 97.38%

Hence, the probability that it will last longer than 10 years if you randonly purchase one item is 97.38%
