Raj polled 100 students in his class to compare the number of hours that boys and girls played video games each week. The results of his survey are shown below. Which gender shows greater variability in their playing time?

Hours of Video Game Time per Week for Boys
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 9 to 17. A line divides the box at 14.5.

Hours of Video Game Time per Week for Girls
A box-and-whisker plot. The number line goes from 0 to 28. The whiskers range from 0 to 28, and the box ranges from 3 to 15. A line divides the box at 6.
Boys show greater variability because the 3rd quartile for boys is 17 but only 15 for girls.
Boys show greater variability because the median playing time for boys is 14.5 but only 6 for girls.
Girls show greater variability because the interquartile range for girls is 12 for girls but only 8 for boys.
Girls show greater variability because the data for the girls is skewed toward the lower end of the box plot.

Step-by-step explanation:

7÷7/4

in these cases we multiply by the reciprocal

7× 4/7

7 and 7 can be cancelled with each other

the remaing answer = 4

Answer:

1/4

Step-by-step explanation:

First, since the numerator is 7 you want to see how many times you can divide that.

So, you can only divide 7 by 7 1 time so that turns into 1.

Hence, your numerator is now 1 and denominator stays the same so its..

Answer:

  8

Step-by-step explanation:

Apparently, you want to evaluate ...

  0.1m +8 -12n

for m = 30 and n = 1/4.

Put the numbers where the corresponding variables are and do the arithmetic.

  = 0.1×30 +8 -12×(1/4) = 3 + 8 -3

  = 8

Answer:

20n2-4n-1

Step-by-step explanation:

You combine like terms, so you add 16n2 with 4n2 to get 20n2. Then you add n with -5n to get -4n. Finally, you add 1 with -2 to get -1.

Answer:

Terminal point: (0, 1); sinФ = 1 ⇒ A

Step-by-step explanation:

In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis.

In a unit circle

∵ Ф = 90°

→ By using the 2nd rule above

∴ The terminal point is (0, 1)

∴ sinФ = 1

∴ Terminal point: (0, 1); sinФ = 1

Answer:

11.8

Step-by-step explanation:

because those two 5.9 if you look those two segments put together make a line that is the same length as x so if you add them up it's 11.8

Answer:

see below

Step-by-step explanation:

We can use the law of sines

sin 80             sin B

--------------- = -------------

31                       14

Using cross products

14 sin 80 = 31 sin B

14/31  sin 80 = sin B

.984807753 = sin B

Taking the inverse sin of each side

sin ^ -1 ( .444751888) =  B

26.41 = B

The sum of the angles of a triangle is 180

A+B+C = 180

80 + 26.41 + C =180

106.41 + C = 180

C = 73.59

We can use the law of sines to find c

sin 80             sin 73.59

--------------- = -------------

31                       c

c sin 80 = 31 sin 73.59

c =  31 sin 73.59 / sin 80

c = 30.20

AB = 30.20

Step-by-step explanation:

Answer:

Options (1) and (3)

Step-by-step explanation:

Option (1)

f(x) = x²+ 3

We can rewrite the function in the equation form as,

y = x² + 3

By interchanging y by x,

x = y² + 3

Now we solve it for y,

y² = x - 3

y = ±√(x - 3)

So the inverse function is,

[tex]f^{-1}(x)=\pm \sqrt{x-3}[/tex]

It's a function.

Option 2

d(x) = -9

Equation form of the function is,

y = -9

Replacing y by x,

x = - 9

Therefore, inverse function will be,

x = -9

Inverse is not a function

Option 3

m(x) = -7x

Equation form of the function,

y = -7x

Interchanging y by x,

x = -7y

Now solve for x,

y = [tex]-\frac{1}{7}x[/tex]

So the inverse function will be,

[tex]m^{-1}(x)=-\frac{1}{7}x[/tex]

Inverse is a function.

Option 4

p(x) = |x|

As this function not a one to one function inverse function is not possible.

Inverse of |x| is not a function.
