1. What is the slope of a line parallel to -8x + y = 2?

kotegsom [21]

Answer:

slope of the parallel line = 8

Step-by-step explanation:

Parallel lines have the same slope. To determine the equation of the other line, you need to transform the given linear equation into its slope-intercept form, y = mx + b:

-8x + y = 2

Add 8x to both sides to isolate y:

-8x + 8x + y = 8x + 2

y = 8x + 2 (this is the slope-intercept form where the slope (m) = 8, and the y-intercept (b) = 2).

Given that the slope of the first equation is 8, then we can assume that the slope of line parallel to -8x + y = 2 will also be 8.

Sarah is taking a test. The test is designed to produce an overall mean score of 85 with a standard deviation of 5 for all test

Arturiano [62]

Answer:

Option D)

The area below the standardized test score is 0.8413

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 85

Standard Deviation, σ = 5

We are given that the distribution of score is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(score is below 90)

$P( x < 90) = P( z < \displaystyle\frac{90 - 85}{5}) = P(z < 1)$

Calculation the value from standard normal z table, we have,

$P(x < 90) =0.8413 = 84.13\%$

Thus, the correct answer is

Option D)

The area below the standardized test score is 0.8413

A fishbowl shaped like a sphere is filled with water the fishbowl has a diameter of 16 inches which measurement is closest to th

Nikolay [14]

Answer:

The volume = 2143.573 cubic inches

Step-by-step explanation:

∵ The volume of the sphere = $\frac{4}{3}\pi r^{3}$

∵ The diameter of the sphere is 16 inches

∴ Its radius = 16 ÷ 2 = 8 inches

∵ The fishbowl is filled

∴ The volume of the water = the volume of the fishbowl

∴ The volume of the water = $\frac{4}{3}\pi(8^{3})=2143.573$ cubic inches
