Each bar includes the left-end value but not the right-end value. For example, the first bar includes dogs that weigh 60 pounds and 68 pounds but not 80 pounds.

Step-by-step explanation:

Answers:

How many dogs weigh at least 100 pounds?

14 + 5+ 3 + 1 = 23 dogs.

How many dogs weigh exactly 70 pounds?

is unknown, so will be 60-79 .

How many dogs weigh at least 120 and less than 160 pounds?

8 dogs weigh 120 less than 160 pounds.

How much does the heaviest dog at the show weigh?

is unknown, but could be between - 160-179

What would you consider a typical weight for a dog at this dog show? Explain your reasoning.

A typical dog weighs can be 100 - 120.

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
