Answer:

As below

Step-by-step explanation:

using eq from problem 4)   y = -45x + 1080

then use the point slope formula with the slope of the above line at -45 and plug in your given point of (8, 240)

y-y1 = m(x-x1)   where m is the slope above

y-240 = -45 (x - 8 )  this is an equation for the line but the teacher probably wants the slope intercept form... the formula is y = mx + b

soooo...

y-240 = -45x + 360

y = -45x +360 + 280

y =  -45x + 640

there you go :)

A curve is describe by the following parametric equations:
soldi70 [24.7K]

Answer:

A. The curve is a parabola with a vertex at (3,-4) and is traced from left to right for increasing values of t.

Step-by-step explanation:

x = 3 + t

y = t² − 4

Eliminating the parameter:

t = x − 3

y = (x − 3)² − 4

This is an upwards parabola with a vertex at (3, -4).

x = 3 + t, so as t increases, x increases.

So the curve is traced from left to right.

HELP PLEAAASEEE Ireland opened a bag or skittles and recorded the colors and their frequencies.
Anna11 [10]

The correct answer is 25%

<h3>What is Relative Frequency?</h3>
  • The number of times an event occurs divided by the total number of events occurring in a given data.

<h3>How to solve the problem?</h3>
  • This problem can be solved by following steps.
  • The data of color and frequency is given in table.
  • We need find the relative frequency for Purple

First calculate the the total number of frequency

18+20+10+16

= 64

The total number of frequency is 64

Hence the relative frequency of purple is 16/64

Therefore , relative frequency of purple is 1/4 = 0.25

Therefore 25% of purple candies are there
