Answer:

1. D

2. E

3. B

4. C

5. A

5. F

Step-by-step explanation:

The median can be found at the line inside of the box, the heaviest weight would be found at the right end of the line, and the smallest weight would be found at the left, the interquartile range is the difference of one end of the box to the other, and the range is the difference of the largest number of the entire diagram, from the smallest number.

Hope this helps you!

Answer:

Florida: The weight range = 10

Tennessee: The interquartile range = 4

Tennesse: Median Weight = 76

Florida: Median Weight = 80

Florida: Weight of the heaviest child = 84

Tennesse: Weight of the smallest child = 71

Step-by-step explanation:

Florida: How to find the weight range

The range of a data set is the difference between the minimum and maximum. To find the range, calculate xn minus x1.

R = xn − x1

Therefore, the weight range in Florida is 10

Tennessee: How to find the interquartile range

To find the interquartile range (IQR), first, find the median (middle value) of the lower and upper half of the data set. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.

71, 72, 73, 74, 75, 76, 77, 78, 79, 80

Q1 = 74

Q2 = 78

78 - 74 = 4

Therefore, the interquartile range in Tennesse is 4

Tennesse: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 75.5

Therefore, the median weight of Tennesse is 76

Florida: Median Weight

The median x˜ is the data value separating the upper half of a data set from the lower half.

Arrange data values from lowest to the highest value

The median is the data value in the middle of the set

If there are 2 data values in the middle the median is the mean of those 2 values.

x˜ = 79

Therefore, the median weight of Florida is 80

Florida: Weight of the heaviest child

Since the smallest number in Florida is 84,

Therefore, the weight of the heaviest child in Florida is 84

Tennesse: Weight of the smallest child

Since the smallest number in Tennesse is 71,

Therefore, the weight of the smallest child in Tennesse is 71

Lera25 [3.4K]

Answer:

$\bar X= 33.79167$

$s= 12.06497$

$SE= \frac{s}{\sqrt{n}}= \frac{12.06497}{\sqrt{24}}=2.463$

$Median= \frac{30+31}{2}= 30.5$

Step-by-step explanation:

For this case we have the following data:

23, 16, 21, 24, 34, 30, 28, 24, 26, 18, 23, 23, 36, 37, 49, 50, 51, 56, 46, 41, 54, 30, 40, and 31

We can calculate the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X= 33.79167$

Then we can calculate the standard deviation with this formula:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}$

And replacing we got:

$s= 12.06497$

And the sample size for this case is n =24. We can calculate the standard error with this formula:

$SE= \frac{s}{\sqrt{n}}= \frac{12.06497}{\sqrt{24}}=2.463$

And the median for this case since the sample size is 24 first we need to sort the data on increasing order and we got:

16 18 21 23 23 23 24 24 26 28 30 30 31 34 36 37 40 41 46 49 50 51 54 56

And for this case the median would be the average from the position 12 and 13 and we got:

$Median= \frac{30+31}{2}= 30.5$

Name the Solid.

Mila [183]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

base = 11 km

height 1 = 7 km

height 2 = 10 km

a) Name of the solid = Triangular prism

b) The base is a triangle

c) Volume

Formula

Volume = 1/2 base x height 1 x height 2

-Substitution

Volume = 1/2 (11) x (7) x (10)

-Simplification

Volume = 1/2(770)

-Result

Volume = 385 km³

Answer:

$h=\frac{3}{2}$

Step-by-step explanation:

$V=\frac{1}{3} \pi r^2h$

$\frac{1}{18} \pi =\frac{1}{3}\pi (\frac{2}{3} / 2 )^2 h$

$\frac{1}{18} =\frac{1}{3} (\frac{2}{6})^2 h$

$\frac{1}{18} =\frac{1}{3} (\frac{4}{36})h$

$\frac{1}{18} =\frac{4}{108} h$

$h=\frac{1}{18}*\frac{108}{4}$

$h=\frac{6}{4}$

$h=\frac{3}{2}$

3 plss help Solve for x ...........

Delicious77 [7]

They are alternate interior angles so they add up to 90.

8x-4+60 = 90 would be the equation.

Now, just combine the like terms.

8x+56 = 90

8x = 34

x = 4.25
