Answer:

mean height = 30.5

Step-by-step explanation:

To find an estimate for the mean height, we need to use a pondered weight of the height of the plants.

The midpoints of each interval of height are:

0 to 10 -> 5

10 to 20 -> 15

20 to 30 -> 25

30 to 40 -> 35

40 to 50 -> 45

50 to 60 -> 55

Using the frequencies as the weights, we have:

mean height = (1*5 + 4*15 + 7*25 + 2*35 + 3*45 + 3*55) / (1+4+7+2+3+3)

mean height = 30.5

Number of people can hold in each car = 10

Solution:

Number of cars in the Blazing Bullet = 6

Total number of people can ride at one time = 60

Number of people can hold at one Bullet car = ?

Let n be the number of people in each car can hold.

Now write a equation to find the number of people in each car.

Number of cars × number of people in each car = Total number of people

⇒ 6 × n = 60

⇒ 6n = 60

Now, solving this equation.

⇒ 6n = 60

Divide both sides of the equation by 6.

$$ \Rightarrow\frac{6n}{6} = \frac{60}{6}$

$$ \Rightarrow n=10$

⇒ n = 10

Hence 10 people can hold in each car.

Answer:

see below PLEASE GIVE BRAINLIEST!!

Step-by-step explanation:

A) 2.40A ≦ 9.60

B) You can choose to purchase between 0 and 4 avacados. 4 is the maximum you can buy because 2.40 x 4 = 9.60 and that is all the money you have and more than 4 would make the equation incorrect. 0 is the least you can buy since you can't purchase a negative amount of something.

So, A ≦ 4

Rewrite the expression using GCF and distributive property. 64x-24

Ede4ka [16]

The greatest common factor between 64 and 24 is 8

Let's divide both terms in the expression by 8 and leave the expression in parenthesis...

Like this!

64x -24

$\frac{64x}{8} - \frac{24}{8}$

8x - 3

Leave 8 we divided outside the parenthesis

Now we have this!

8( 8x - 3)

This is the distributive property form!
