Which division problem does the model below show? 4 fraction bars. The fraction bars are labeled 1 and each have 6 boxes underne

Ksivusya [100]

Answer:

4 divided by one-sixth = 2

Step-by-step explanation:

Given 4fraction bars

If each fraction bars has 6boxes, then we can get the total boxes for 4fractiom bars as shown;

1 fraction bars = 6boxes

4fraction bars = x

Cross multiply

1 × x = 4×6

x = 4× 6/1

x = 4 ÷ 1/6

Hence the division problem that modelled the expression is 4 ÷ 1/6

4÷1/6 = 4×6/1

4÷1/6 = 24

Option A is correct

Answer:

For the 99th percentile, we have X = 206 seconds.

Step-by-step explanation:

Problems of normally distributed samples can be 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:

$\mu = 138.5, \sigma = 29$
