Hey Jay!

To find the mean, you just need to add all the numbers together then divide them by the amount of numbers in total. (I hope that makes)

So let's start

6+2+59+12+11+9+9+54+54+46+2+32+43+11 all of them divide by 14

350/14
Median= 25

I hope this answer helps! Let me know if you have further questions about the answer. Best of luck!

The mean is the average of the numbers. You add up all numbers and divide the result for how many numbers there are (14)

6+2+59+12+11+9+9+54+54+46+2+32+43+11 = 350

Mean = 350/14 = 25

A company packages its milk powder in cylindrical

Roman55 [17]

Answer:

704 cm²

Step-by-step explanation:

The circumference of the cylindrical container is given by 2πr.

Now, r = radius of the base

If the diameter of the base is 14 cm then the radius will be 7 cm.

So, the circumference = $\frac{2 \times 22 \times 7}{7} =44$ cm.

Now, the label around the surface of the container placed 2 cm from top and bottom.

Therefore, the width of the label is (20 - 2 - 2) = 16 cm and the length is 44 cm.

Hence, the area of each label is (44 × 16) = 704 cm² (Answer)

Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probabili

3241004551 [841]

Answer:

$P(p>0.43) = 0.0436$

Step-by-step explanation:

Given

$p = 40\%$ -- proportion of baseball players

$n = 781$ --- selected sample

Required

Determine P(p>43%)

First, calculate the z score using:

$Z = \frac{\^{p}-p}{\sqrt{\frac{p(1-p)}{n}}}$

This gives:

$Z = \frac{48\%-40\%}{\sqrt{\frac{40\% *(1 - 40\%)}{781}}}$

Convert % to decimal

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *(1 - 0.40)}{781}}}$

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *0.60}{781}}}$

$Z = \frac{0.43-0.40}{\sqrt{\frac{0.24}{781}}}$

$Z = \frac{0.03}{\sqrt{0.00030729833}}$

$Z = \frac{0.03}{0.01752992669}$

$Z = 1.71$

So:

$P(p>0.43) = P(Z>1.71)$

$P(p>0.43) = 1 - P(Z$

$P(p>0.43) = 1 - 0.9564$

$P(p>0.43) = 0.0436$

Finds the GCF of 18a, 20ab, and 6ab.<br><br><br> Could you show your work? That would be awesome.

MrMuchimi

Segregate the coefficients and variables for a moment.

For the coefficients,
the factors of 18 are 1, 2, 3, 6, 9, and 18;
the factor of 20 are 1, 2, 4, 5, 10, and 20;
the factor of 6 are 1, 2, 3, and 6.

The "common factors" of these 3 numbers are 1 and 2.
Since 2 is greater than 1, the GCF is 2.

For variables, identify the smallest value of degree (or exponent) of "like" variables to get the GCF. Because the given monomials do not have a degree and also 8a doesn't have variable "b", automatically the GCF is a.

Multiplying together for the final GCF yields 2a. That is the answer.
