Answer: Shown below

Step-by-step explanation:

Bisects mean split in half, so this shape has a symmetrical line in the form of RT. Using that, we find:
RU = RS = 8

ST = UT = 23

SV = VU = 5

SU = SV + VU = 10

First you would find a common denominator. If 40 is the LCM then you would have to add playing games, instruction,warm-up, and cool-down. Then you will subtract the sum from the total class time and bam! You get your answer!

A whatjapanthinks.com survey asked residents of Japan to name their favorite pizza topping. The possible responses included the
grin007 [14]

Answer:

See Explanation

Step-by-step explanation:

Solving (a):

First, we categorize each data (to get their frequencies):

PI PI PI PI PI PI PI PI PI ---> Frequency: 9

S S S S S S S S---> Frequency: 8

V V V V V V V V V V V V  V ---> Frequency: 13

PO PO PO---> Frequency: 3

B ---> Frequency: 1

C  C ---> Frequency: 2

Total = 36.

The frequency table is as follows:

\begin{array}{cc}{Pizza\ Topping} & {Frequency} & {Beacon\ or\ Ham} & {9} & {Seafood} & {8} \ \\ {Vegetable\ and Fruit} & {13} & {Poultry} & {3} & {Beef} & {1} & {Cheese} & {2}\ \end{array}

Solving (b): The relative frequency and percentage.

Relative frequency is calculated by dividing each frequency by the total frequency.

So, we have:

{Beacon\ or\ Ham} = \frac{9}{36} =0.250

Seafood = \frac{8}{36} =0.222

Fruits\ and\ Vegetable = \frac{13}{36}=0.361

Poultry = \frac{3}{36}=0.083

Beef = \frac{1}{36}=0.028

Cheese = \frac{2}{36}=0.056

The percentage is calculated by multiplying the frequency by 100%.

So, we have:

Bacon\ or\ Ham = 0.250 * 100\% = 25.0\%

Seafood = 0.222 * 100\% = 22.2\%

Fruits\ and\ Vegetable= 0.361 * 100\% = 36.1\%

Poultry = 0.083 * 100\% = 8.3\%

Beef = 0.028 * 100\% = 2.8\%

Cheese = 0.056 * 100\% = 5.6\%

Solving (c): Percentage that mentioned vegetables and fruits, poultry, or cheese?.

This is calculated as:

\%Percent = Vegetable\ and\ fruits + Poultry + Cheese

\%Percent = 36.1\% + 8.3\% + 5.6\%

\%Percent = 50\%

Write the equation of the graphed in NO SPACES ALL LOWERCASE<br> Help !!
cupoosta [38]

Answer:

The equation of the graphed line is:

  • y = 2

Step-by-step explanation:

From the graph, it is clear that the line is a horizontal line at y = 2.

We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.

In other words, the equation of the horizontal line would always get the form:

y = k

where k is the y-intercept of the line.

Determining the y-intercept of the line:

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the graph, it is clear

at x = 0, y = 2

Thus, the y-intercept k = 2

Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation

y = 2

Therefore, the equation of the graphed line is:

  • y = 2
