Answer:

Approximately 57 minutes.

Step-by-step explanation:

5 ÷ 45 = 1/9

1/9 · 8.5 = 17/18

An hour = 60 mins so

60 ÷ 18 = 10/3

10/3 · 17 = 56.6666667

also known as 56.67 minutes if rounded to hundreds, 56.7 minutes if rounded to the tenths, and 57 minutes if rounded to a whole number.

A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $12
CaHeK987 [17]

Solution:

Let each pond of  jelly beans cost $x.

and each pond of almonds cost $y.

Then we can write

6x+2y=12.......(i)

3x+5y=15.....(ii)

Now solve these two equations together using substitution we get

3x=15-5y

30-10y+2y=12\\
\\
-8y=12-30\\
\\
-8y=-18\\
\\
y=2.25\\
\\
3x=15-5y=15-5*2.25=3.75\\
\\
x=1.25

Hence each pond of jelly bean cost 1.25$

Each pond of almond costs 2.25$

Select the correct answer.
tatyana61 [14]

Answer:

The answer is the first choice, that the outcomes (getting a 2, 4, or 6 or getting a 1, 3, or 5) are equally likely because the frequencies are close.

Step-by-step explanation:

The second choice isn't true because there isn't a lot of variation. If there was, this would mean they aren't equally likely.

The third choice isn't true because it doesn't make a statement about why the odd/even identity of the sets should affect the likelihood. (Besides, we know they are equally likely.)

The fourth choice isn't true because there is not a lot of difference in the relative frequency.
