1 = 100%

21 ÷ 50 = 0.42

0.42 = 42%

Add:

100 + 42 = 142

Answer = 142%

Hope this helped☺☺

What is the equation of the line that passes through the points (1, −10) and (−4, −7)?

nignag [31]

Hi there! :)

First, let's find the slope using this formula:

m= $\frac{y2-y1}{x2-x1}$

m= $\frac{-7-(-10)}{-4-1} \\\frac{-7+10}{-5} \frac{3}{-5} =-\frac{3}{5}$

Now, use the Point-Slope formula:

y-y1=m(x-x1)

y-(-10)=-3/5(x-1)

y+10=-3/5x+3/5

y=-3/5x+3/5-10

y=-3/5x-9.4

Hope this helps..

One card from a deck of cards Is selected, it's is replaced, and another card is chosen. What is the probability that the first

Elis [28]

Answer:

1/ 8

Step-by-step explanation:

Given that:

Number of red cards in deck = 26

Number of diamonds in deck = 13

Number of cards in deck = 52

Recall :

Probability = required outcome / Total possible outcomes

Probability of choosing a red :

P(red) = 26 / 52 = 1/2

With replacement :

Probability of diamond :

P(diamond) = 13 / 52 = 1/4

Hence,

Probability of first card red, then second card diamond equals

P(red) * P(diamond)

1/2 * 1/4

= 1/8

iii) on the second day there is a fine of $0.25

iv) on the third day there is a fine of $0.20

v) for each of the remaining 7 days there is a fine of $0.10 for each day

therefore the total fine for the remaining seven days is = 7 $\times$ $0.10 =

$0.70

vi) therefore the total fine for the book is = $0.25 + $0.20 + $0.70 = $1.15

Therefore the correct option is b.) $1.15
