vazorg [7]

add together all (3) percentages 60+70+80=210
subtract the answer from 300 (300 because there were 3 percentages) 300-210=90
divide this answer by 3 (also because there were 3 percentages) 90/3=30
the probability of the person walking without a red light is 30%

How many 1 1/2 liter bottles of water does it take to fill a 16 liter jug

timurjin [86]

11 bottles are needed to fill a 16 liter jug

Solution:

Given that, there is a 16 liter jug

There are $1\frac{1}{2}$ liters of bottle

Let us first convert the mixed fraction to improper fraction

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

$\rightarrow 1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2} = 1.5$

Thus the bottle is of 1.5 liter

We have to find the number of 1.5 liter bottles needed to fill 16 liter jug

Divide 16 by 1.5 to get result

$Number\ Of\ Bottles = \frac{16}{1.5} = 10.67 \approx11$

Thus 11 bottles are needed to fill a 16 liter jug

What is the range of the function in this table?

marin [14]

Hello from MrBillDoesMath!

Answer:

Choice B: {1,2,4}

Discussion:

The range of the function is the set of "y" values shown in the table, which is 1,4,4,2. As sets do not contain duplicate elements, the range is {1,2,4). This is Choice B

Thank you,

MrB
