Answer:

21 square yards

Step-by-step explanation:

Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.

In this case, L = 21 feet and W = 9 feet.

Therefore, A = 21 feet * 9 feet = 189 square feet

We need the answer in square yards. We know that 1 feet equals 1/3 yard (1 feet = 1/3 yard)

As we need square yards, we just square the equation above.

1^2 square feet = (1/3) ^2 square yards

1 square feet = 1/9 square yards

The area is 189 square feet, so we just multiply by 189 on both sides to do the conversion to square yards.

189 square feet = 189*1/9 square yards

189 square feet = 21 square yards

The area of the flower bed is 21 square yards

21 times 9 which equals 189 feet and there are 3 feet in a yard so we do 189 divided by 3 which equals 63 so the answer is 63 square yards.

The time for a professor to grade an exam is normally distributed with a mean of 16.3 minutes and a standard deviation of 4.2 mi
dem82 [27]

Answer:

62.17% probability that a randomly selected exam will require more than 15 minutes to grade

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 16.3, \sigma = 4.2

What is the probability that a randomly selected exam will require more than 15 minutes to grade

This is 1 subtracted by the pvalue of Z when X = 15. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{15 - 16.3}{4.2}

Z = -0.31

Z = -0.31 has a pvalue of 0.3783.

1 - 0.3783 = 0.6217

62.17% probability that a randomly selected exam will require more than 15 minutes to grade

In 2001 the mint indoor pool vault record was 20 and 1/6 the women’s record for the indoor pool vault was 15 and 5/12 FT what is
blondinia [14]

Answer:

35 and 7/12 feet is the combined height of the two records.

Step-by-step explanation:

Height of the indoor pool vault record for men = 20 and 1/6 ft =\frac{121}{6} ft

Height of indoor pool vault record for women = 15and 5/12 ft =\frac{185}{12} ft

The combined height of the two records :

\frac{121}{6} ft+\frac{185}{12} ft

\frac{121\times 2}{6\times 2} ft+\frac{185}{12} ft

\frac{242}{12} ft+\frac{185}{12} ft

\frac{242+185}{12} ft=\frac{427}{12}=35\frac{7}{12}

35 and 7/12 feet is the combined height of the two records.
