Nastasia [14]3 years ago

Answer:

The error is the slope is -4 and the correct is, the slope is  -\frac{1}{4}

Step-by-step explanation:

You must put the equation in the form of y = m x + b, where

  • m is the slope
  • b is the y-intercept

Let us put the equation n the form above

∵ x = -4y

→ Switch the two sides

∴ -4y = x

→ Make the coefficient of y equal 1 by divide both sides by -4

∵ \frac{-4y}{-4} = \frac{x}{-4}

∴ y = \frac{x}{-4}

→ Write \frac{x}{-4} as -\frac{1}{4} x

∴ y =  -\frac{1}{4} x

→ Compare it by the form above

∴ m =  -\frac{1}{4}  and b = 0

∴ The slope of the is  -\frac{1}{4} , and the y-intercept is 0

∴ The error is the slope is -4 and the correct is the slope is  -\frac{1}{4}

I got D.

There's a few ways to solve it; I prefer using tables, but there are functions on a TI-84 that'll do it for you too. The logic here is, you have a standard normal distribution which means right away, the mean is 0 and the standard deviation is 1. This means you can use a Z table that helps you calculate the area beneath a normal curve for a range of values. Here, your two Z scores are -1.21 and .84. You might notice that this table doesn't account for negative values, but the cool thing about a normal distribution is that we can assume symmetry, so you can just look for 1.21 and call it good. The actual calculation here is:

1 - Z-score of 1.21 - Z-score .84 ... use the table or calculator

1 - .1131 - .2005 = .6864

Because this table calculates areas to the RIGHT of the mean, you have to play around with it a little to get the bit in the middle that your graph asks for. You subtract from 1 to make sure you're getting the area in the middle and not the area of the tails in this problem.

Roger ran eight laps around a mile track during PE on Monday. Answer each question in the space provided. Part A How many feet d
Gre4nikov [31]

Answer:

A) 10,560 ft. B) 32 more laps.

Step-by-step explanation:

A) Four laps around a track is equal to one mile, and there are 5,280 feet in one mile. If Roger ran eight laps, he ran two miles. Therefore: 5,280 ft. times 2, is equal to 10,560 ft.

B) We know that Roger ran two miles Monday. We also know that four laps around a track is equal to one mile. In order to run 10 miles, he would have to run 40 laps, and since he already ran 8, we can subtract that from 40. You are left with 32 more laps.
