20% off original price that is $25
so 0.20 * 25 = 5
so that means that the new price is $20
you save $5

Answer:

Larger for the sample of Canadians

Step-by-step explanation:

The larger the sample size, the smaller the standard deviation (sampling variability) associated with the sample means and vice-versa.

The sample of Canadians is smaller, it is expected that their sampling variability is larger than the sample of Canadians based on the rule that as the sample size increases, the standard deviation of the means decreases; and as the sample size decreases, the standard deviation of the sample means increases

What is the solution to 3/4b=8

soldier1979 [14.2K]

Answer:

$b=\frac{32}{3}$

Step-by-step explanation:

$\frac{3}{4}b=8$

Multiply both sides by 4:

$4\times \frac{3}{4}b=8\times4$

$3b=32$

Divide both sides by 3:

$\frac{3b}{3}=\frac{32}{3}$

$b=\frac{32}{3}$

Hye Lim drank 4/3 gallons of water in 11/2 hours. At this rate, how long will it take her to drink 4 gallons of water?

snow_lady [41]

Answer:

16.5 hours

Step-by-step explanation:

Here is the explanation. As Hye drinks 4/3 gallons of water in 11/2 hours, we have a constant rate. There are 12 thirds in 4, so we are trying to find how long it takes Hye to drink 12/3 gallon. In this case, 4/3x3=12/3, so we multiply 11/2 by 3 as well, which gives us 33/2 hours. 33/2 in decimal form is 16.5 hours. Hope it helps!

Answer:

12,000 m³

Step-by-step explanation:

Area of it's base = 900 m²
Height of the pyramid = 40 m

The volume of a pyramid = 1/3 × area of base × height

= 1/3 × 900 × 40

= 300 × 40

= 12,000 m³

Jamie can read at a speed of 65 pages per hour. If she reads a novel that has 400 pages, how long will it

horsena [70]

To find the answer set up an equation:
$400 \: pages \times \frac{1 \: hour}{65 \: pages} =$
Using this set up we can cross our units of pages since they are on opposite side of the proportion, leaving us with the desired units of hours.

Then divide 400 by 65 which will give us our answer: 6.15 or about 6 hours for Jamie to finish her reading.
