Animals were trapped in a city and later released into the wild. A random sample of the data is provided in the table below.

Fynjy0 [20]

Answer:

1,400

Step-by-step explanation:

We take the sample proportion of skunks and estimate for the entire population.

Sample:

140 skunks out of 230 + 140 + 120 = 490 animals.

140/490 = 0.28571428571

If a random sample of 5,000 animals are trapped in the city, how many skunks would be estimated to be included?

0.28571428571 out of 5000. So

0.28571428571*5000 = 1429

Close to 1400, which means that the answer is given by option C.

Box A has a volume of 512 cubic meters. Box B is similar to box A. To create Box B, Box A's dimensions were divided by 2. What i

bearhunter [10]

Answer : The volume of box B is $64m^3$

Step-by-step explanation :

Given :

Volume of box A = 512 cubic meter

Let us assumed that the box A and box B are cubes and the dimensions of cube are same i.e, 'a'.

Volume of box A = V = $a\times a\times a=a^3$

As per question,

When dimensions of box A divided by 2 then the volume of box B will be:

Volume of box A = V' = $\frac{a}{2}\times \frac{a}{2}\times \frac{a}{2}=\frac{a^3}{8}$

As the box B is similar to box A. So, the volume of box B will be:

Volume of box B = V' = $\frac{a^3}{8}$

$V'=\frac{a^3}{8}=\frac{V}{8}$

$V'=\frac{512m^3}{8}=64m^3$

Therefore, the volume of box B is $64m^3$

A _______ represents the idea of "if and only if." Its symbol is a double arrow, left right arrow↔.

Bond [772]

Answer:

A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a $\leftrightarrow$ .

Step-by-step explanation:

We have been given an incomplete sentence. We are supposed to fill in the given blank.

A _______ represents the idea of "if and only if." Its symbol is a $\leftrightarrow$ .

We know that "if and only if" stands for bi-conditional statement, which represents either both statements are true or both are false.

The symbol $\leftrightarrow$ represent a bi-conditional statement.

Therefore, our complete statement would be: A <u>bi-conditional statement</u> represents the idea of "if and only if." Its symbol is a $\leftrightarrow$ .

Andy cut rope for an activity at outdoor camp. He had 504 centimeters of rope to cut into equal-length pieces. How many of the w

mina [271]

Answer: B, C, E

Step-by-step explanation:

For us to know if the options are correct, we just have to multiply the length the rope was cut into by the number of pieces and check if it equals 504 centimeter.

A. 12 pieces of 42.3 centimeter long rope.

= 12 × 42.3

= 507.6

This is wrong

B. 15 pieces of 33.6 centimeter long rope

= 15 × 33.6

= 504cm

This is correct

C. 16 pieces of 31.5 centimeter long rope

= 16 × 31.5

= 504cm

This is correct

D. 20 pieces of 25 centimeter long rope

= 20 × 25

= 500cm

This is incorrect

E. 35 pieces of 14.4 centimeter long rope

= 35 × 14.4

= 504cm

This is correct

Therefore, the correct option are B, C and E.
