Answer:

9. $\frac{1}{10}$ fraction.

10. $\frac{3}{10}$ fraction.

Step-by-step explanation:

In the given table, we get, Andrea hiked $\frac{2}{5}$ of the total trail, Jon hiked $\frac{1}{2}$ of the total trail and Callie hiked $\frac{4}{5}$ of the total trail.

9. Therefore, Jon hiked $(\frac{1}{2} - \frac{2}{5}) = \frac{5 - 4}{10} = \frac{1}{10}$ fraction than Andrea hiked.

10. Therefore, Callie hiked $(\frac{4}{5} - \frac{1}{2}) = \frac{8 - 5}{10} = \frac{3}{10}$ fraction than Jon hiked. (Answer)

A bucket contains 40 red balls, 25 black balls, and 35 white balls. Two balls are drawn at random. What is the probability that

Lyrx [107]

Answer:

$Probability = \frac{1}{5}$ or $Probability = 0.2$

Step-by-step explanation:

Given

$Black = 25$

$White = 35$

$Red = 40$

Required

Determine the probability of selecting Black and Red

First, we need to calculate the number of red and black balls

The probability is calculated as thus:

$Probability = P(Black\ and \ Red) \ or\ P(Red\ and \ Black)$

Convert to mathematical expressions

$Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)]$

Solve for each probaility;

$P(Black) = \frac{Black}{Total} = \frac{25}{100}$

$P(Red) = \frac{Red}{Total} = \frac{40}{100}$

So, we have:

$Probability = [P(Black) *P(Red)] + [P(Red) *P(Black)]$ $Probability = [\frac{25}{100} *\frac{40}{100}] + [\frac{40}{100} *\frac{25}{100}]$

$Probability = [\frac{1000}{10000}] + [\frac{1000}{10000}]$

$Probability = [\frac{1}{10}] + [\frac{1}{10}]$

$Probability = \frac{1+1}{10}$

$Probability = \frac{2}{10}$

$Probability = \frac{1}{5}$

or

$Probability = 0.2$

What is the slope-intercept equation of this line?

Gekata [30.6K]

Answer:

y = -2x+8

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/x2-x1)

m = ( -4 -8)/(6 - 0)

= -12/6

= -2

The y intercept is 8 from the point (0,8)

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -2x+8
