In his free time Gary spends 10 hours per week on the internet and 9 hours per week on video games. If Gary has 5 hours of free

cluponka [151]

Answer:

Percentage of free time Gary spends on playing video games and using internet = 54.29%

Step-by-step explanation:

Given:

Gary spends 10 hours per week on the internet.

Gary spends 9 hours per week on video games.

Gary has 5 hours free time per day.

To find the percentage of free time Gary is using to play video game and use the internet.

Solution:

Total number of hours of free time Gary has per week = $5\times 7=35$

[As there are 7 days in a week so we multiply by 7]

Total number of hours of free time Gary spends on playing video games and using internet per week = $10+9=19$

Percentage of free time Gary spends on playing video games and using internet per week can be calculated as :

⇒ $\frac{\textrm{Total time spent on playing video games and using internet per week}}{\textrm{Total free time in a week}}\times 100$

⇒ $\frac{19}{35}\times 100$

⇒ 54.29% (Answer)

Answer:

Box-plot = {54, 65, 69, 73, 76}

Step-by-step explanation:

The data provided for the number of desks on each floor of Texter Corporate is as follows:

S = {54, 60, 65, 66, 67, 69, 70, 72, 73, 75, 76}

There are a total of n = 11 floors.

A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,

Minimum (shown at the bottom of the chart)

First Quartile (shown by the bottom line of the box)

Median (or the second quartile) (shown as a line in the center of the box)

Third Quartile (shown by the top line of the box)

Maximum (shown at the top of the chart).

Arrange the data in ascending order as follows:

S': = {54 , 60 , 65 , 66 , 67 , 69 , 70 , 72 , 73 , 75 , 76}

The minimum value is:

Minimum = 54

The maximum value is:

Maximum = 76

As there are odd number of values the median is the middle value.

Median = 6th value = 69

The first quartile is the median of the first half of the data.

S'₁ = {54 , 60 , 65 , 66 , 67}

First quartile = 3rd value = 65

The third quartile is the median of the second half of the data.

S'₂ = {70 , 72 , 73 , 75 , 76}

Third quartile = 3rd value = 73

Thus, summarized data for the box plot is:

Box-plot = {54, 65, 69, 73, 76}

28.9-32.5 i will be fine i just forget the steps

Mademuasel [1]

Answer:

-3.6

Step-by-step explanation:

Since 32.5 is greater than 28.9, you just subtract 32.5 from 28.9 then add an equal sign. 32.5-28.9=3.6. With the negative, it would be -3.6

Answer:

this is the answer for (03.01 LC)

$\sqrt{50}$

Step-by-step explanation:

You have use the Pythagorean Theorem a^{2} + b^{2} = c^{2}

So this is my work

$x^{5} + x^{5} = c^{2} \\25 + 25 = c^{2} \\50= c^{2} \\\sqrt{50} = \sqrt{c^{2} } \\\sqrt{50} = c\\$

extra notes

If you didn't know, you cancel exponents with roots.

So the c^{2} is cancled by aka \sqrt{c}

You can't simplify $\sqrt{50}$ so it stays like that

Answer: the answer for (03.06 LC)

Step-by-step explanation:

In pic

Just look for r after substituting the variables

Rewrite the given equation so there is a single power of 5,000 on each side. then, set the exponents equal to each other.

ICE Princess25 [194]

Answer: A

Step-by-step explanation:

$(\frac{1}{5000})^{2z} * (5000)^{2z+2} = 5000$

$(5000)^{-2z} * (5000)^{2z+2} = (5000)^{1}$

$(5000)^{-2z+2z+2}= (5000)^{1}$

$(5000)^{0+2}= (5000)^{1}$

$(5000)^{2}= (5000)^{1}$

2 = 1
