I think it is 24
Because
KL=48 x (16/32)
KL= 48 x 0.5
KL = 24

Answer:

Step-by-step explanation:

KL = 48 × (16/32)

KL = 48 × 0.5

KL = 24

The stemplot below represents the number of bite-size snacks grabbed by 37 students in an activity for a statistics class.

Simora [160]

Answer:

The distribution of the number of snacks grabbed is skewed right with a center around 18 and varies from 12 to 45. There are possible outliers at 38, 42, and 45.

Step-by-step explanation:

First, we can see if the graph is symmetric. A symmetric graph is even on both sides of the center. As there are a lot more students that grabbed a small number of snacks, and the data is not even around the center (which is somewhere around 20 or 30 snacks). This means that the graph is not symmetric, making the second answer incorrect.

Next, we can check if the graph is skewed right or left. If the left of the graph represents a smaller amount of snacks and the right of it represents a higher number of snacks, we can see that most of the data is on the left of the graph. There are a few values to the right, but the overwhelming amount of data is on the left, making the distribution skewed to the right. This keeps the first and last answers possible

Moreover, we can find the center of the distribution. This is generally equal to the median, which is 18, so the center is around 18

After that, we can see what the values vary from. The lowest tens value is 1, and the lowest ones value in that is 2, making the lowest value 12. Similarly, the highest tens value is 4, and the highest ones value there is 5, making the range 12 to 45. This leaves the last answer, but we can check the outliers to make sure.

With the data, we can calculate the first quartile to be 15, the third quartile to be 21.5, and the interquartile range to be 21.5-15 = 6.75 . If a number is less than Q₁ - 1.5 * IQR or greater than Q₃ + 1.5 * IQR, it is a potential outlier. Applying that here, the lower bound for non-outliers is 15 - 6.5 * 1.5 = 5.25, and the upper bound if 21 + 6.5 * 1.5 = 30.75. No values are less than 5.25, but there are four values greater than 30.75 in 32, 38, 42, and 45. There are possible outliers at 38, 42, and 45, matching up with the last answer.

Solve the inequality and graph <br>2(-6n-5)<-3(4n+2)<br>thanks!

Mekhanik [1.2K]

Answer:

All real numbers are solution for the inequality.

Step-by-step explanation:

Given expression:

$2(-6n-5)$

Solving the inequality.

Using the distribution.

$(2(-6n))+(-2(-5)$

$-12n-10$

Adding $12n$ to both sides.

$-12n+12n-10$

We have,

$-10$

The above statement is always true and thus the inequality has all real number solutions.

The number line graph for the inequality can be shown.

A large sample of tires from cabs driven within a city have an average tire tread depth of 0.25cm at the end of the winter. If t

frutty [35]

Answer:

0% probability cab tires depths would be shallower than 0.25cm.

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:

$\mu = 2.2, \sigma = 0.33$

What is the probability cab tires depths would be shallower than 0.25cm.

This probability is the pvalue of Z when X = 0.25. So

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

$Z = \frac{0.25 - 2.2}{0.33}$

$Z = -5.9$

$Z = -5.9$ has a pvalue of 0.

0% probability cab tires depths would be shallower than 0.25cm.
