The area of the rect. is 100 ft times 64 ft, or 6400 ft^2.

Let's list factors of 6400: 64,100

64= 2^6

100= 2^2*5^2

Here we see that 2 appears 8 times as a factor, and 5 appears 2 times:

6400 = 2^6 * 10^2 = 2^8*5^2

Franklin saved money to buy art supplies

Nikolay [14]

<u>Question</u>:

Franklin saved money to buy art supplies. He used 1/5 of his savings to buy brushes. He used 1/2 of his savings to buy paint. What fraction of his savings does he have remaining?

Answer:

Franklin had $\frac{3}{10}$ of his saving left.

Step-by-step explanation:

Amount used to buy brushes = 1/5

Amount used to buy paint = 1/2

Solution:

Let the remaining amount be x

then ,

x = 1- (amount used on buying brushes + amount used for buying paints)

$x = 1- (\frac{1}{5} + \frac{1}{2})$

$x = 1- (\frac{2+5}{10})$

$x = 1- (\frac{7}{10})$

$x =\frac{10-7}{10}$

$x =\frac{3}{10}$

Researchers measured the data speeds for a particular smartphone carrier at 50 airports. The highest speed measured was 72.6 Mbp

Lapatulllka [165]

Answer:

a. 54.05 Mpbs.

b. 2.745... standard deviations.

c. The z-score is 2.745....

d. The carrier's highest data speed is significantly high.

Step-by-step explanation:

a. The difference between the highest measured data speed and the mean is 72.6 - 18.55 = 54.05 Mbps.

b. The amount of standard deviations of 54.05 Mbps is equal to this value divided by the standard deviations, so we yield $\frac{54.05}{19.69} = 2.745...$ standard deviations.

c. The z-score is equal to the difference between the mean and a data point in standard deviations, so the z-score is 2.745....

d. 2.745... is not between -2 and 2, so the carrier's highest data speed is not insignificant - so it's significantly high.

Write the equation that describes the line with slope = 1 and y-intercept= 5/2 in slope-intercept form.

Nonamiya [84]

Answer: y=x+5/2

Step-by-step explanation:

using the slope intercept formula, y=mx+b where m is the slope and b is the y-intercept, you can substitute the two values to get y=x+5/2. Please note that the slope, m, is one so it's not shown.
