Based on the table, how much did Francis earn per hour?

Answer:

A darts player practices throwing a dart at the bull’s eye on a dart board. Her probability of hitting the bull’s eye for each throw is 0.2.

(a) Find the probability that she is successful for the first time on the third throw:

The number F of unsuccessful throws till the first bull’s eye follows a geometric

distribution with probability of success q = 0.2 and probability of failure p = 0.8.

If the first bull’s eye is on the third throw, there must be two failures:

P(F = 2) = p

2

q = (0.8)2

(0.2) = 0.128.

(b) Find the probability that she will have at least three failures before her first

success.

We want the probability of F ≥ 3. This can be found in two ways:

P(F ≥ 3) = P(F = 3) + P(F = 4) + P(F = 5) + P(F = 6) + . . .

= p

3

q + p

4

q + p

5

q + p

6

q + . . . (geometric series with ratio p)

=

p

3

q

1 − p

=

(0.8)3

(0.2)

1 − 0.8

= (0.8)3 = 0.512.

Alternatively,

P(F ≥ 3) = 1 − (P(F = 0) + P(F = 1) + P(F = 2))

= 1 − (q + pq + p

2

q)

= 1 − (0.2)(1 + 0.8 + (0.8)2

)

= 1 − 0.488 = 0.512.

(c) How many throws on average will fail before she hits bull’s eye?

Since p = 0.8 and q = 0.2, the expected number of failures before the first success

is

E[F] = p

q

=

0.8

0.2

= 4.

Answer:

A.

Step-by-step explanation:

the diameter is 1.8 in.

diameter to circumference is multiplying the diameter by pi

1.8*= about 5.66 (Rounded to the nearest hundredth)

the 5.66 in. is going around 15 times

multiply 5.66 and 15

5.66*15=84.9

the best answer would be A.

14          63

then solve which comes out to be 9.

Answer: 63 divided by 7 =9

Step-by-step explanation:

14 divided by 2 is 7, and $63 divided by 7 is 9

So 9 tickets.

Answer:

Your pay rate is:  

$ 7  per hour

Your friend's pay rate is  :

$ 9  per hour

Explanation:

So if it takes you  8  hours to make  $ 56 , you can just divide the total money earned by the time.  So it would be  56 ÷ 8  which is  7 .

And if takes your friend  4  hours to make  $ 36 , you can divide like we just did . So it would be  36 ÷ 4  which is  9 .

So you make  $ 7  per hour and your friend makes  $ 9 per hour.

Answer:

1/2 or 2

Step-by-step explanation:

If the original triangle length of Side A to C is 4, then the answer is two. If the original traingle length is Side A to C on the original triangle is 8, then the answer is 1/2.

The scale factor of the dilation is 1/2.

Scale factor is defined as the number or the conversion factor which is used to change the size of a figure without changing its shape. It is used to increase or decrease the size of an object. The scale factor can be calculated if the dimensions of the original figure and the dimensions of the dilated (increased or decreased) figure are known.

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given:

Before dilation

AC= 8, BC= 10 abd AB= 6

After dilation

AC= 4, BC= 5 and AB= 3

Now, scale factor

Scale factor = Dimensions of the new shape / Dimensions of the original shape.

So,

scale factor = 4/8  or 5/10  or  3/6 = 1/2

Hence, the scale factor is 1/2.

Answer:

the slope (m) = 3/4

Step-by-step explanation:

Answer:

M=3/4

Step-by-step explanation:

Rise/run

9/12=3/4

The resulting equation after substitution is

5x + 4(-2x + 6) = 3

quite literally you replaced y with what it equals (as said in the second equation)

you then distribute the 4 within the parenthesis

5x + -8x + 24 = 3

You make it easier

5x - 8x +24  = 3

you combine like terms

-3x + 24 = 3

you subtract 24 from both sides

-3x = -21

you divide both sides by -3

meaning x = 7

you then use that value x = 7 and substitude it for the x in the other equation.

That makes the y equation

y = -2(7) + 6

you then solve

y = -14+6

y = 6 - 14

y = -8

Martin would save $1.01 per game by going to PC Richard & Son

Step-by-step explanation:

To solve this question, you have to divide the amount of money by the amount of games. You already know Best Buy's price for 1 game here (59.99).

Since the price is 117.96 for 2 games at PC, you can do

117.96÷2=58.98

59.99-58.98= $1.01

Oh, and even if you do 294.90÷5, you'd get the same thing.
