Answer:

y = $\frac{1}{4}$ x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 4x + 3 ← is in slope- intercept form

with slope m = - 4

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-4}$ = $\frac{1}{4}$ , hence

y = $\frac{1}{4}$ x + c ← is the partial equation of the perpendicular line

To find c substitute (8, 1 ) into the partial equation

1 = 2 + c ⇒ c = 1 - 2 = - 1

y = $\frac{1}{4}$ x - 1 ← equation of perpendicular line

How many ways can a committee of five be chosen from 120 employees to interview prospective applicants.

REY [17]

Answer:

190578024 ways.

Step-by-step explanation:

We are asked to find the number of ways in which a committee of 5 be chosen from 120 employees to interview prospective applicants.

We will use combinations to solve our given problem.

$_{r}^{n}\textrm{C}=\frac{n!}{(n-r)!r!}$ , where,

n = Total number of items,

r = Number of items being chosen at a time.

Upon substituting our given values in above formula, we will get:

$_{5}^{120}\textrm{C}=\frac{120!}{(120-5)!5!}$

$_{5}^{120}\textrm{C}=\frac{120!}{115!*5!}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116*115!}{115!*5*4*3*2*1}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116}{5*4*3*2*1}$

$_{5}^{120}\textrm{C}=\frac{120*119*118*117*116}{120*1}$

$_{5}^{120}\textrm{C}=\frac{119*118*117*116}{1}$

$_{5}^{120}\textrm{C}=\frac{190578024}{1}$

Therefore, the committee of five can be chosen from 120 employees in 190578024 ways.

A piece of fabric costs 5.29 a yard which is an estimated cost of 16.3 yards of the fabric

ozzi

The answer choices are not posted, but this is how you calculate the answer. Multiply $5.29 per yard by the total number of yards purchased.
= $5.29 per yard * 16.3 yards= $86.227

*or $86.23 rounded to the hundredths place

ANSWER: The exact answer is $86.227 for 16.3 yards. Not knowing the answer choices, you could estimate to $86.00, you could estimate to $86.23, you could even estimate to $90.00.
Hope this helps! :)
