Answer:

110.5π

Step-by-step explanation:

The formula for the area of a circle is π r ²

R stands for radius. So, the radius is 10.5, you have to square it meaning 10.5 * 10.5.

110.5 and now you multiply by π so the answer is 110.5π

Answer: C

<BFE is 148 degrees

Step-by-step explanation:

We have angles <BFC (57 degrees) and <CFD (34 degrees), but what is <DFE?

1. The angle symbol in the vertexes shows that <BFC is congruent to <DFE, meaning that they are the same

2. Knowing this, we can safely say that <DFE is equal to 57 degrees because <BFC is also 57 degrees.

3. Now, we have all the angles we need to find out <BFE.

4. <BFC+<CFD+<DFE=<BFE

5. Substitute to get

57+34+57=<BFE

91+57=<BFE

148=<BFE

6. Now we know that the answer is 148 degrees.

Answer:

0.3736

Step-by-step explanation:

46.7 percent of  [tex]\frac{4}{5}[/tex] is 0.3736.

To find 46.7% of [tex]\frac{4}{5}[/tex].

So,

[tex]\frac{46.7}{100}[/tex] × [tex]\frac{4}{5}[/tex]

[tex]\frac{0.467}{100}[/tex] × [tex]\frac{4}{5}[/tex]

⇒ [tex]0.3736[/tex]

Therefore,  46.7% of  [tex]\frac{4}{5}[/tex] is 0.3736.

Answer:

The average height of team b is 62 inches.

Step-by-step explanation:

Mean:

The mean of a data-set is the sum of all values in the data-set divided by the number of values, that is:

[tex]M = \frac{s}{n}[/tex]

Sum:

Team a: Mean of 68 inches, 2x members.

Team b: Mean of y inches, x members.

So

[tex]s = 68*2x + yx = x(136 + y)[/tex]

Number of athletes:

[tex]n = 2x + x = 3x[/tex]

What is the average height of team b?

[tex]66 = \frac{x(136+y)}{3x}[/tex]

[tex]66 = \frac{136 + y}{3}[/tex]

[tex]136 + y = 198[/tex]

[tex]y = 198 - 136 = 62[/tex]

The average height of team b is 62 inches.

Complete question;

The mean weight of an adult is 76 kilograms with a variance of 100.

If 142 adults are randomly selected, what is the probability that the sample mean would differ from the population mean by more than 1.5 kilograms

Answer:

7.34% 0r 0.0734

Step-by-step explanation:

We have mean u = 76

Standard deviation = square root of variance

Sd = √100 = 10

N = 142

S = 10/√142

= 10/11.92

= 0.84

X is going to differ by more than 1.5 or less than 1.5

76-1.5 = 74.5

76+1.5 = 77.5

At x = 74.5

Z = (74.5-76)/0.84 = -1.79

At x = 77.5

Z = (77.5-76)/0.8 = 1.79

P value of z at -1.79 = 0.036

P value of z at 1.79 = 0.9633

0.9633-0.0367 = 0.9266

Which is 92.66% probability of differing by 1.5

Probability it differs by more:

P+92.66 = 100

P = 100-92.66

= 7.34% or 0.0734

Answer:

  arithmetic; common difference of 5

Step-by-step explanation:

It usually works well to check differences first. Here, they are ...

  8 -3 = 5

  13 -8 = 5

These are the same value, so the sequence is arithmetic with a common difference of 5.

Answer:

  7, 10

Step-by-step explanation:

It often works well to look at the factor pairs that form the product.

  70 = 1×70 = 2×35 = 5×14 = 7×10

The sums of these are 71, 37, 19, 17. The last pair of factors is the one of interest:

  7 and 10.

36q² − 64 = 0

=> 36q² = 0 + 64

=> 36q² = 64

=> q² = 64/36

=> q² = 16/9

=> q = √(16/9)

=> q = √16/√9

=> q = ± 4/3

Answer:

q =±4/3  

Step-by-step explanation:

36q² − 64 = 0

Add 64 to each side

36q² =64

Divide each side by 36

36q² /36 =64/36

q² =64/36

Take the square root of each side

sqrt(q²) =± sqrt(64/36)

q = ±8/6

q =±4/3  

Answer:

135

Step-by-step explanation:

Given that :

Total score obtained by Peter, Jan and Maxim = 269

Let :

Peter's score = x

Jan's score = y

Maxim's score = z

x + y + z = 269

x > (y + z)

For x to be greater Than y + z ;

Then x > (269 / 2) ; x > 134.5

The least possible x score is 135

Hence, Peter's least possible score is 135.

Answer:

$71.415 or $71.42 is the selling price and the taxing is 1

Step-by-step explanation:

This is because I just rounded that extra 5 to make the 41 cents into 42 cents also y=79.35(.9) is the equation you needed to solve so just put 79.35(.9) into a calculator and you'll get 71.415 also 10% turns into a decimal 0.10 and then you subtract it from 1 as a whole and you'll get 0.9. I'm not really a mathmatician but I just got done learning this so I know what to do.
