The second quartile of a data set is 4.2. Which statement about the data values is true?

2 answers:

6 0

The second quartile is also the median. which is 50% of the data. So 1/2 of the data lies below it, and 1/2 of the data lies above it.
the correct answer would be A. the data value of 2.5 will lie below the second quartile.

A Quartile is a 1/4 of the values which are arranged in numerical order. Quartile 2 (Q2), which is also called the Median of the data set.It means half of the data set on each side of the Quartile 2.
Hence theb est answer is:
a. the data value 2.5 will lie Below the second quartile.
Because 2.5 is lower value than the 4.2 and it must lie on the left of 4.2.

ryan has a mix of action and sports games for a total of 39 video games his action collection is three more than half his sports

iVinArrow [24]

Answer:

He have 15 action games and 24 sports games.

Step-by-step explanation:

Given:

Ryan has a mix of action and sports games for a total of 39 video games his action collection is three more than half his sports collection.

Now, to find the number of action games and sports games.

Let the sports games be $x.$

As, given his action collection is three more than half his sports collection.

Thus, the action games = $3+\frac{x}{2}$ .

Total number of video games = 39.

So, we set an equation to get the number of action games and sports games:

$x+(3+\frac{x}{2})=39$

$x+3+\frac{x}{2} =39$

Subtracting both sides by 3 we get:

$x+\frac{x}{2} =36$

$\frac{2x+x}{2}=36$

$\frac{3x}{2} =36$

Multiplying both sides by 2 we get:

$3x=72$

Dividing both sides by 3 we get:

$x=24.$

The sports games he have = 24.

Now, to get the action games we substitute the value of $x$ :

$3+\frac{x}{2}$

= $3+\frac{24}{2}$

= $3+12$

= $15.$

The action games he have = 15.

Therefore, he have 15 action games and 24 sports games.

Find the volume of a right circular cone that has a height of 9.1 m and a base with a circumference of 12.1 m. Round your answer

Orlov [11]

Answer:

$V=35.3\ m^3$

Step-by-step explanation:

-Given the cone's height is 9.1m and the Circumference is 12.1

#We use the circumference formula to calculate the radius:

$C=2\pi r\\\\12.1=2\pi r\\\\r=\frac{12.1}{2\pi}=\frac{6.05}{\pi}\ cm$

-The volume of the cone using the radius above can then be calculated as follows:

$V=\pi r^2\frac{h}{3}\\\\=\pi\times(\frac{6.05}{\pi})^2\times \frac{9.1}{3}\\\\\\=35.3\ m^3$

Hence, the cone's volume is $35.3\ m^3$

At midnight, the temperature was 34°F. By 6:00 a.m. it had dropped 8°, and by noon it had increased by 11°. What was the tempera

olga_2 [115]

Answer:

The temperature at noon was 37 °F.

Step-by-step explanation:

Given:

Temperature at midnight is 34 °F.

Reduction in temperature by 6:00 a.m. is 8°. So, temperature after reduction is given as the difference in temperature at midnight and morning.

Therefore, temperature by 6:00 a.m. in the morning is given as:

Reduced temperature = Midnight temperature - Reduction in temperature.

Reduced temperature = 34 °F - 8 °F = 26 °F.

Now, by noon, the temperature is increased by 11 °F. Therefore, the final temperature by noon is addition of 11 degree to the temperature that was in the morning. Therefore,

Temperature at noon = Temperature in morning + Increase in temperature.

Temperature at noon = 26 °F + 11 °F = 37 °F.

So, the temperature at noon is a 3 °F increase to the temperature at midnight and is equal to 37 °F.

Eight trucks hold a total of 10 and 1/2 tons of cargo. Half the trucks are

RUDIKE [14]

Answer:

2 large trucks = 14 tons of cargo

1 small truck = 3½ tons of cargo

Equation: x + 2x = 10½

Step-by-step explanation:

8 trucks - 4 large trucks, 4 small trucks

small truck = x

large truck = 2x

First, you need to find out how much cargo 1 large truck and 1 small truck can hold.

x + 2x = 10½

3x = 21/2

3x = 10.5

x = 3.5 or 3½

1 small truck can hold 3½ tons of cargo, and 1 large truck can hold 7 tons of cargo.

Next, you need to substitute and find how much cargo 4 large trucks can hold. (Remember: 1 large truck = 7 tons of cargo)

= 2(7)

= 14 tons of cargo

4 large trucks can hold 14 tons of cargo.

Finally, you know that one small truck equals 3½ tons of cargo.
