Answer:

Probability of selecting someone who doesn't watch ABC 16/45 or 35.56%

Step-by-step explanation:

There are a total of 45 people in the survey.  Of those 45, the number that doesn't watch ABC is 12 + 4 = 16.  So the probability is 16/45.

A peeting zoo has 5 lambs 11 rabbits 4 goat and 4 piglets find the ratio of goat to the total number of animals.then explain its
Otrada [13]
Ratio is the number of something beside another number of something i.e. ( There are 2 boys and three girls so the Ratio would be 2:3) Therefore the answer would be 5:11:4:4. Yiou want the goats ratio of the total number of animals so we will add all animals EXcEPT the goat. 5+11+4 = 20 so the ratio would be 4:20

Clark has a box of nickels and dimes that totals $1.90. there are a total of 27 coins. how many nickels and dimes does he have?
Andrej [43]
$0.05(n) + $0.10(d) = $1.90
n + d = 27
n + d - d =27 - d
n = 27 - d

$0.05(27-d) + $0.10(d) = $1.90
1.35 - 0.05d + 0.10d = $1.90
1.35 +0.05d = $1.90
1.35 - 1.35 +0.05d = $1.90 -1.35
0.05d = 0.55
0.05d/0.05 = 0.55/0.05
d = 11

n = 27 - 11
n = 16

$0.05(16) + $0.10(11) = $1.90
$0.80 + $1.10 = $1.90
$1.90 = $1.90

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
enot [183]

2x - 3y = - 13

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

First obtain the equation in slope-intercept form

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

calculate m using the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 5 ) and (x₂, y₂ ) = (- 2, 3 )

m = \frac{3-5}{-2-1} = \frac{-2}{-3}= \frac{2}{3}

y = \frac{2}{3} x + c ← partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 5 ), then

5 = \frac{2}{3} + c ⇒ c = \frac{13}{3}

rearrange the equation into standard form

multiply through by 3

3y = 2x + 13 ( subtract 3y and 13 from both sides )

2x - 3y = - 13 ← in standard form
