The distance around the lot is the perimeter of the lot, which has a formula:

P 2L + 2W

We can fill in using the info given:

$P=2(\frac{9}{8})+2(\frac{9}{10})$ which multiplies to

$P=\frac{18}{8}+\frac{18}{10}$ and finding a common denominator:

$P=\frac{90}{40}+\frac{72}{40}$ and adding, gives you

Richard’s store sells pineapples and grapefruits. Pineapples originally cost $5.15 apiece, and grapefruits originally cost $2.25

sveta [45]

Answer:

c. The price of grapefruits experienced a reduction 6.01 percentage points greater than the price of pineapples.

Step-by-step explanation:

The original price of Pineapples=$5.15

New price of Pineapples=$3.88

Find change in price of Pineapples

Change in price=original price- new price

$=5.15-3.88=1.27$

The price of Pineapple was reduced by $1.27

% reduction in price

(reduction value/original value) × 100

$=\frac{1.27}{5.15} *100=24.66$

=24.66%

The original price of grape fruits=$2.25

New price of grape fruits=$1.56

Change in price of grape fruit

Change in price= original price -new price

$=2.25-1.56=0.69$

% reduction in price of grape fruits

(reduction value/original value)×100

$=\frac{0.69}{2.25} *100=30.67$

=30.67%

Answers

The fruit that has its price reduced by a greater percentage is grape fruit

How many percentage points greater = 30.67%-24.66% = 6.01 points

Answer:

D) We are 95 percent confident that the mean difference in scores for all children in the program is between 20.1 points and 23.9 points.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

95 percent confidence interval (20.1,23.9)

We are 95% sure that the population mean(that is, the mean for all children in the program) is in this interval. So the correct answer is given by option D.
