Which is the 10th term to the geometric sequence 2/9,2/3,2,...?

A random group of 5 boys and a random group of 5 girls were selected to determine whether boys or girls text more. The table sho

<h2>Answer:</h2>

The inference that can be made by the given data sets is: Option: B

B) The median is the best measure to use to compare the sets.

<h2>Step-by-step explanation:</h2>

We are given a data set for Boys and Girls as:

Boys: 19, 23, 26, 27, 30

Girls: 14, 17, 21, 25, 168

clearly we could see that there is a outlier in the data of girls i.e. 168 as it is a too high value as compared to other data values in the set.

This means that there is a greater spread in the number of texts sent by girls as compared to boys.

and data for girls have a greater variance as compared to boys.

Hence, option: A is discarded.

Also,

Median of Boys= 26

and Median for Girls = 21

This means that Median for the number of texts sent by boys is more than those by girls.

Hence, option: D is discarded.

Also we know that an outlier affect the mean and median of the data.

Hence, option: C is discarded.

We know that median of the data is the central tendency of the data and best compare the set of data.

Hence, Option: B) is the correct answer.

Question 4(Multiple Choice Worth 5 points)

ZanzabumX [31]

Answer:

95°

Step-by-step explanation:

y° = 180° - (55° + 30°)

y° = 180° - 85°

y ° = 95°

y = 95

x = y ( vertical angles)

x = 95°

Consider the following sets.

ludmilkaskok [199]

Answer:

[2,3] is the answer

assuming you didn't have equal symbols under the inequality signs, you know $\le$ and $\ge$ .

Step-by-step explanation:

Ok let's solve 3x+4>13 or 1/2 x+3<4.

Let's begin with 3x+4>13.

3x+4>13

Subtract 4 on both sides:

3x>9

Divide both sides by 3:

x>3

Now the other 1/2 x +3<4.

Subtract 3 on both sides:

1/2 x<1

Multiply both sides by 2:

x<2

So we have x>3 or x<2

If we graph this, this will give us better idea of what is and isn't a solution.

~~~~~~~~O x<2

O~~~~~~ x>3

------------(2)---------(3)---------

The only numbers not included are between 2 and 3 (inclusive).

So if x is between [2,3] then A or B has no solution.

A student sets up two reactions. Reaction 1 uses 0.180 mol/L of reactant, and Reaction 2 uses 0.510 mol/L of reactant. How many

il63 [147K]

Given the data from the question, reaction 2 is 2.83 times faster compared to reaction 1

<h3>Data obtained from the question</h3>

Molarity of reaction 1 (R₁) = 0.180 mol/L
Molarity of reaction 2 (R₂) = 0.510 mol/L
Comparison =?

<h3>How to determine the comparison of reaction 2 to reaction 1</h3>

We can determine how many times faster is reaction 2 to reaction by doing the following:

R₂ / R₁ = 0.510 / 0.180

R₂ / R₁ = 2.83

Cross multiply

R₂ = 2.83 × R₁

From the above illustration, we can see that reaction 2 is 2.83 times faster than reaction 1

A local movie theater sells two bag sizes of popcorn. Both bags are in the shape of a rectangular prism. Bag A measures 4" long,

Natali5045456 [20]

Answer:

the height of bag b is 7

Step-by-step explanation:

first, find the volume of bag a.

volume formula:

length * width * height = volume

length = 4

width = 3.5

height = 6

substitute the values into the formula

4 * 3.5 * 6 = volume

84 = volume

the volume of bag A is 84

next, find the height of bag b

volume formula:

length * width * height.

length = 8

width = 3

volume = 168 (84 * 2)

8 * 3 * h = 168

24h = 168

24h/24 = 168/24

h = 168/24

h = 7

the height of bag B is 7
