Question:

In a neighbourhood pet show, each of the animals entered is equally likely to win. if there are 7 dogs, 6 cats, 3 birds, and 2 gerbils entered, what is the probability that a bird will win the top prize?

Answer:

Probability that a bird will win the top prize is 0.167

Step-by-step explanation:

Given:

The number of  dogs  = 7

The number of  cats = 6

The number of  birds  = 3

The number of gerbils = 2

To Find:

Probability that a bird will win the top prize = ?

Solution:

Let us first find the total number of  pets .

The Total number of pets = 7 + 6 + 3  + 2 =  18

Now the probability of  a bird will win the top prize is

=> \frac{\text {Number of birds}}{\text{ Total number of pets}}

=>\frac{3}{18}

=> \frac{1}{6}

=>0.167

What is the slope of the line 3x – 9y = 4? –3 –negative StartFraction one-third EndFraction StartFraction one-third EndFraction
Arturiano [62]

Answer:

1/3

Step-by-step explanation:

3x – 9y = 4

We need to solve for y

Subtract 3x from each side

3x – 9y-3x = 4-3x

-9y = -3x+4

Divide each side by -9

-9y/-9 = -3x/-9 +4/-9

y = 1/3 x -4/9

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

y =1/3x -4/9

The slope is 1/3

A)
C(102) = 102^2 – 400 = 10004
</span>C(100) = 100^2 – 400 = 9600

average rate of change = (10004<span>- 9600)/(102 - 100) = 404/2 = 202

</span>B)
C' = 2x = 2 (100) = 200

John has 4/5​ of a pound of dog food left to share equally among 6 dogs in his pet shop. ​How many pounds of food can he give to
arlik [135]

Answer:

2/15 pound of dog food

Step-by-step explanation:

John has 4/5​ of a pound of dog food left to share equally among 6 dogs in his pet shop. ​How many pounds of food can he give to each dog?

From the above question, we can deduce that:

6 dogs = 4/5 pound of dog food

1 dog = x pound of dog food

Cross Multiply

6 dogs × x pound = 1 dog × 4/5 pound of dog food

x pound = 1 dog × 4/5 pound of dog food/6 dogs

x pounds = 4/5 ÷ 6

x pounds= 4/5 × 1/6

x pounds = 4/30

x pounds = 2/15 pound of dog food

Therefore,if the dog food is shared equally, he can give each dog 2/15 pound of dog food.

PLS HELP:Find the side length, C.<br> Round to the nearest tenth.
mestny [16]

Answer:

\huge\boxed{c = 14.9}

Step-by-step explanation:

Using Cosine Rule

c^2 = a^2 + b^2 -2abCosC

Where a = 11 , b = 7 and C = 110

c^2 = (11)^2+(7)^2-2(11)(7)Cos 110

c^2 = 121+49-154 (-0.34)\\c^2 = 170+52.7\\c^2 = 222.7

Taking sqrt on both sides

c = 14.9
