Brady is conducting an experiment using a spinner with four different colors: red, orange, blue, and green. He spun the spinner 40 times and recorded the following data.



Based on the data in the table, if Brady spins the spinner 240 times, he predicts the spinner will land on red roughly A. 48, B. 24, C. 12, D. 36 times. He also predicts the spinner will land on green roughly A. 108, B. 72, C. 48, D. 36
more times than it will land on red.

Answer:

30.9 square cm

Step-by-step explanation:

subtract area of circle from area of square

Area of square = 12² or 144  

(each side is twice the radius)

Area of circle = 6²π or 113.1

Answer:

[tex]V_{0} = e^{-rt}[/tex] ∑ [tex]uPdx^{(1-p)} *S_{o}[/tex]  

Step-by-step explanation:

The Payoff to the holder at maturity T = X1{ST > K}, where X = pre-specified cash sum.

Current value of asset price = Sn  after evolvement of asset price in reference to binomial model

Hence at every  step value changes to SnU and Snd

where ; d < e^rΔT < u  and Δ T = length of each step

u = ups

d = downs

Determine the time zero price of the above option

First we will find the price after each period

After one period :

when the price goes up, Sn + ΔT = Su

when the price goes down, Sn + ΔT = Sd

After  period two

For Su

when price goes up, Sn +2ΔT = Su2

when price goes down, Sn +2ΔT = Sud

For Sd

when  price goes down, Sn +2ΔT = Sd2

when price goes up, Sn +2ΔT = Sdu

To get the time zero price we will have to apply the same procedure in reverse position den get the sum pf all ups and downs which is

sum of all ups and downs = [tex]e^{-rT}[/tex]∑ [tex]uPd^{(1-p)}[/tex]

[tex]V_{0} = e^{-rt}[/tex] ∑ [tex]uPdx^{(1-p)} *S_{o}[/tex]

Step-by-step explanation:

       Since, tigonometric identities are equal on both the sides (left hand side and right hand side) of the equation, Options (B), (C), and (D) represent the dientities.

Option A

cos(x + y) + cos(x - y) = cos²2x - sin²2y

Left hand side = cos(x + y) + cos(x - y)

                        = cosx.cosy - sinx. siny + cosx.cosy + sinx.siny

                        = 2(cosx.cosy)

But the left side of the equation is (cos²2x - sin²2y).

Hence both the sides are not equal and it's not an identity.

OPtion (B).

sin(x - π) = -sinx

Left hand side = sin(x - π)
                        = -sinx sin(x - π)

                        = sinx.cosπ - cosx.sinπ

                        = -sinx - 0  

                        = -sinx  [Right hand side]

Since, both the sides are equal, it's an identity.

Option (C).

sin(x + y) - sin(x - y) = 2cosx.siny

Left hand side = sin(x + y) - sin(x - y)

                        = sinx.cosy + cosx.siny - sinx.cosy + cosx.siny

                        = 2cosx.siny

                         = Right hand side

Since, both the sides are equal, it's an identity.

Option (D).

cos(x + y) + cos(x - y) = 2cosx.cosy

Left hand side = cos(x + y) + cos(x - y)

                        = cosx.cosy - sinx.siny + cosx.cosy + sinx.siny = 2cosx.cosy                        

                        = Right hand side

Since, both the sides of the equation are are equal.  It's an identity.

       Therefore, Option (B), (C), (D) are the correct options.

Answer:

Generally, your current ratio shows the ability of your business to generate cash to meet its short-term obligations. A decline in this ratio can be attributable to an increase in short-term debt, a decrease in current assets, or a combination of both.

Sometimes, a low current ratio could suggest problems with inventory management, ineffective or lax standards for collecting receivables, or an excessive cash burn rate. Increases in the current ratio over time may indicate a company is "growing into" its capacity (while a decreasing ratio may indicate the opposite).

The 25% of the shaded checker board has pieces on it.

To check that, we need to solve the expression below:

Percent = 100%*(# shaded squares with pieces)/(total # of shaded squares)

There are a total of 32 shaded squares, and in 8 of them we can see pieces, then we can replace these values in the formula above to get:

Percent = 100%*(8/32) = 25%

That is the percent of the shaded checker that has pieces.

Answer:

How many miles does he ride his bike there and back?

6 miles.

What information is extra?​

The hour at which he leaves his house.

Step-by-step explanation:

We know that he rides 3 miles each way.

Then he rides 3 miles from his house to his friend's house, and another 3 miles from his friend's house to his house.

So he rides 3 miles both times, if we add that, we get:

3 miles + 3 miles = 6 miles

So:

How many miles does he ride his bike there and back?

6 miles.

And to answer the other question, we need to look at the given information that we did not use in this calculation. In this case, is the hour at which he leaves his house.

Notice that we never did use the fact that he leaves his house at 4 p.m.

Then:

Answer:

Breadth is 4cm

Step-by-step explanation:

Perimeter = 24cm

Length= 8cm

let the breadth be x

Perimeter = 2(l+b)

24 = 2(8+x)

24 = 16+2x

24-16 = 2x

8 = 2x

8÷2 = x

4 = x

Therefore, breadth is 4cm

AB = 42.30 m

Step-by-step explanation:

What we are asked to do is to simply find the length of AB.

Since both triangles are similar, therefore their corresponding sides would be proportional to each other.

Thus:

92/82.8 = 47/AB

Cross multiply

92*AB = 82.8*47

92*AB = 3,891.6

AB = 3,891.6/92

AB = 42.30 m(nearest hundredth)

It does not need to be an improper fraction.

For example, the numerator and denominator of 10/11 are both greater than 9, but 10/11 is not an improper fraction.

Answer:

Remember that a number divided by itself is 1. That means if the numerator and denominator are the same, the fraction is equal to 1. So all of the following are equal to 1: 2/2, 3/3, 4/4, and so on and so forth. so a good one you could do is 9/9
