Answer:

6 wins

Step-by-step explanation:

15% chance in winning a particular game also means that you will win 15% of the total number of games, which in this case, is 40.

Number of wins =

[tex]winning \: chance \times total \: games = 0.15 \times 40 \\ = 6[/tex]

Answer:

The measurement of the eighth angle in the octagon is 245 degrees.

Step-by-step explanation:

The following formula calculates the total internal angles in an octagon:

Sum of the interior angle = (n - 2) * 180 degrees,

where n represents the polygon's number of sides. n = 8 for an octagon, so we have:

Interior angle sum = (8 - 2) * 180 = 1080 degrees.

Given that the sum of the seven inner angles is 835 degrees, we can construct the following equation:

835 + x = 1080

where x represents the eighth angle's degree measurement. After finding x, we obtain:

x= 1080 - 835

x = 245 degrees

The eighth angle of the octagon is therefore 245 degrees.

Answer:

Exponential, quadratic, Linear

Step-by-step explanation:

So ok, let me give you a reminder on what these functions are.

So, a linear function is quite literally a strait line. Basically, the values of x and y are being added and subtracted by a ever-constant value.

Next is a quadratic function, which basically a u or upside-down u. The numbers increase, and then decrease, or vise versa. You can think of it like a bird flying up to the clouds, and then gliding back down.

Finally we have exponential functions. Which is a function that gets very, very high. This is because the number is squared over and over again. The bigger the x or y value gets, the bigger it will be next time its squared.

Just for a visual, I took some photos of the different types of functions.

Now, lets get into the problem.

For the first problem:

X is increasing by 1.

Y is increasing by....Lets see.

So it seems y is getting diving by 2 each time the x increases by 1.

It seems sort of like a linear function, right?

Well yes, but if you recall what I said above, the values are being added to or subtracted to. This is division, and is never a exact number. So it cant be that. The values dont go up and then back down, or vise versa like in a quadratic function. Well, could the value of y in this graph be squared by 1/2 to get our answer? Yes! So the answer must be exponential!

Now, lets try to speed through to the next ones.

We can see that the x is changing by 1, while the y changes by a odd and not always the same amount. This istantly means that it cannot be linear. It could be exponential, but if you look closly, you can see that at the end, the values start to decrease. Remember what I said about quadratic function? Then this must be a quadratic function!

That sums up our second function, lets look at our third.

The x is increasing by 1, and the y values are increasing by 6.

Hmm, it seems like each time x increases by 1, y increases by 6. This means it must be a linear function! After all, linear functions increase by a constant amount.

I hope this helps you with your problem and any you have in the future!

Good luck! ; )

Answer:

25%

Step-by-step explanation:

100 or more is only for 1 whisker

1 whisker = 1/4

1/4 = 25%

Step-by-step explanation:

I know that 44÷4=11. So that means P must be 11. But since it's subtracted by 7 we must solve 11+7. Which is 18. So P=18.

Answer:

4: y = 0.75x + 3.75

5: y = 0.75x + 23.25

6: y = 0.75x + 11

Answer:

*Below*

Step-by-step explanation:

Let the number be N.

N divided by 4 leaves 1 as the remainder. This means N - 1 is divisible by 4.

So, we can write N - 1 = 4k1, where k1 is an integer 10 or greater

N divided by 5 leaves 3 as the remainder. This means N - 3 is divisible by 5.

So, we can write N - 3 = 5k2, where k2 is an integer 8 or greater

From above, we get 4k1 - 2 = 5k2

4k1 - 5k2 = 2

k1 = 13, k2 = 10 and the number is XXXXX = 4k1 + 1 = 4(13) + 1 = 53

Answer:

Range: 55

Step-by-step explanation:

Range = subtraction of the smallest number in the data set to the greatest number in the data set.

Greatest number: 1 hr (60 minutes)

Smallest number: 5 minutes

Range = 60 - 5

           = 55

Hope this helps!

Answer:

The mean will change. The range will change.

Step-by-step explanation:

The outlier is 4, it's the one number in the data that isn't close to the other numbers.

The data without the outlier will be 7, 9, 9, 10.

Mode: The mode will still be 9. It is still the number that appears the most in the data.

Median: The median WON'T change. The data is now one value shorter, but the median will still be 9. Before it was 9, and now it's still 9 ((9+9)/2).

Mean: The mean will change because we're excluding one value. Before, the mean was 7.8 (4+7+9+9+10=39, 39/5 = 7.8). NOW it is 8.75 (7+9+9+10=35, 35 / 4 = 8.75).

Range: The range will change. Before it was 10-4, now it is 10-7. The range was originally 6 and now it's 3.

Answer:

$39.33 (rounded to nearest cent)

Step-by-step explanation:

Cost of shirt normally = $65

Cost of shirt for 3 days = [tex]\frac{100-45}{100}[/tex] × $65

                                      = [tex]\frac{55}{100}[/tex] × $65

                                      = $35.75

Cost of shirt on 4th day = [tex]\frac{100+10}{100}[/tex] × $35.75

                                       = [tex]\frac{110}{100}[/tex] × $35.75

                                       = $39.33 (rounded to nearest cent)

Answer:

Liam has 39 chairs.

Step-by-step explanation:

First you have to set up the equation -

4x + 7 = 2x + 23

then isolate the variables

4x - 2x + 7 - 7 = 2x - 2x + 23 - 7

2x = 16

x = 8

then substitute the variable with 8

4(8) + 7 = 39

2(8) + 23 = 39

Liam has 39 chairs.

Answer:
