It is a because each day you run 5 miles, meaning 100 miles is decreasing since you keep running the miles away, for example if you ran for 4 days 100-20, because we multiplied 4x 5( the amount of miles) and now we would have 80 miles to go

It would have to be the first option.

The second option is not correct because you are not adding more than what her goal is.

The third option is not correct because you are not dividing from her goal.

The fourth option is not correct because it would ultimately result in a negative number.

The first option is correct because it subtracts how many days she has ran times 5 from her goal. The resulting answer would show how many miles she has left to reach her goal of 100 miles during that month.

Hope this helps!

Second = 8\ blocks east

Required

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 =100

Take positive square root of both sides

x = \sqrt{ 100

x = 10

5(15-7y/3)+2y=-4<br>solve for y and plz show steps​
Burka [1]

Answer:

75 - 35y / 3 + 2y = -4

( 75 - 35y + 6y ) / 3 = -4 [ Taking LCM ]

( 75 - 29y ) / 3 = -4

75 - 29y = -12

29y = 75+12

29y = 87

y = 3

hope that helps ✌

A data scientist studying a manufacturing process classifies each item produced by the process as either Poor, Acceptable, or Ex
Genrish500 [490]

Answer:

0.214 ; 0.064 ; 0.3859 ; 0.9966 ; 0.135

Step-by-step explanation:

Given the distribution :

Poor ___ Acceptable ____ Excellent

0.25 _____ 0.6 _________ 0.15

The data scientist receives three items produced by the manufacturing process.

Find the chance that:

a. all of items are Acceptable

0.6 * 0.6 * 0.6 = 0.6^3 = 0.214

b. none of the items is Acceptable

P(not acceptable) = 1 - p(acceptable) = 1 - 0.6 = 0.4

0.4 * 0.4 * 0.4 = 0.4^3 = 0.064

c. at least one of the items is Excellent

P(atleast one) = 1 - P(none)

P(not excellent) = 1 - 0.15 = 0.85

P(none is excellent) = 0.85^3 = 0.614125

Hence,

P(atleast one is excellent) = 1 - 0.614125 = 0.3859

d. not all of the items are Excellent

P(not all) = 1 - p(All)

P(all excellent) = 0.15^3 = 0.003375

P(not all are excellent) = 1 - 0.003375 = 0.9966

e. there is one item of each class:

P(poor) * p(acceptable) * p(excellent) * (number of classes)!

0.25 * 0.6 * 0.15 * 3!

= 0.135
