Which of the following expressions is equal to 5^6/5^2

Natali5045456 [20]

Answer:

$\dfrac{5^6}{5^2}$ = $5{\cdot}5{\cdot}5{\cdot}5$

Step-by-step explanation:

The given expression is :

$\dfrac{5^6}{5^2}$

We need to find this expression is equal to what.

$\dfrac{5^6}{5^2}=\dfrac{5^4\times 5^2}{5^2}\\\\=5^4\\\\=5\times 5\times 5\times 5\\\\\text{or}\\\\=5{\cdot}5{\cdot}5{\cdot}5$

Hence, $\dfrac{5^6}{5^2}$ is equal to $5{\cdot}5{\cdot}5{\cdot}5$ . Hence, the correct option is (c).

A teacher is evaluating how students in her first class did on an assessment versus her last class. The box plots show the resul

MrMuchimi

Answer:

The time a student learns mathematics is important for their score

Step-by-step explanation:

Observe the boxes diagrams. Where the horizontal axis represents the score obtained by the students in the test.

The vertical lines that divide the boxes in two represent the value of the median.

The median is the value that divides 50% of the data.

For the class of the morning the value of the median is 50 points, with a maximum value of 80 and a minimum value of 10.

For the afternoon class, the median value is 65 points with a minimum value of 30 and a maximum value of 100.

This indicates that in general, the highest number of high scores were obtained in the afternoon class.

Therefore it can be said that the time a student learns mathematics is important for their score

One year Ron had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched)

Arada [10]

Answer:

Ron's ERA has a z-score of -2.03.

Karla's ERA has a z-score of -1.86.

Due to the lower z-score, Ron had a better yean than Karla relative to their peers.

Step-by-step explanation:

Z-score:

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 question:

Since the lower the ERA, the better the pitcher, whoever's ERA has the lower z-score had the better year relative to their peers.

Ron

ERA of 3.06, so $X = 3.06$
