Hi there!

All you have to do to solve this problem is multiply the amount of money made per hour by the number of hours worked.

In this case, its 7 x 3, which equals 21.

Answer:

-7

...................

To solve this equation, first get rid of the fractions.

We do this by multiplying both sides by the denominator, 2.

So we have (2)(1/2s) = (7/2)(2).

On the left, we have s and on the right, we have 7.

So we have s = 7.

Answer:

36.49 and 35.49

Step-by-step explanation:

Let the two consecutive number be x-1 and x

If their product is 1295, then;

x(x-1) = 1295

x² - x = 1295

x²-x - 1295 = 0

x = 1±√(-1)²-4(-1295)/2

x = 1±√1+5180/2

x = 1±71.98/2

x = 72.98/2

x = 36.49

x - 1 = 35.49

Hence the two numbers are 36.49 and 35.49

Answer:

They got 14 books at $22 and 21 books at $34.

Step-by-step explanation:

From the information given, you can write the following expressions:

x+y=35 (1)

22x+34y=1022 (2), where:

x is the number of books that cost $22

y is the number of books that cost $34

First, you can solve for x in (1):

x=35-y (3)

Then, you can replace (3) in (2) and solve for y:

22(35-y)+34y=1022

770-22y+34y=1022

12y=1022-770

12y=252

y=252/12

y=21

Finally, you can replace the value of y in (3) to find x:

x=35-y

x=35-21

x=14

According to this, the answer is that they got 14 books at $22 and 21 books at $34.

Answer:

133 pieces of 15cm can be cut from the ribbon.

Step-by-Step Explanation:

Length of ribbon = 20 meters

Length needed to be cut = 15 cm

We will convert meters into centimeters.

1 meter = 100 cm

20 meters = 2000 cm

Number of pieces = [tex]\frac{2000}{15}[/tex]

Number of pieces = 133.33

Rounding off to nearest whole number = 133

Hence,

133 pieces of 15cm can be cut from the ribbon.

Elissa can cut 133 ribbons from 20 meters long ribbon and this can be determined by using the unitary method.

Given :

Elisse has 20 meters of ribbon.

The following steps can be used to determine the total number of ribbons of length 15 cm can be cut from 20 meters ribbon:

Step 1 - Remember 1 meter is 100 cm.

Step 2 - If 1m is 100 cm then 20m is equal to:

[tex]=20\times 100[/tex]

= 2000 cm

Step 3 - Elisse cut 15cm long ribbon. So, the total number of ribbons she can cut is:

[tex]=\dfrac{2000}{15}[/tex]

Simplify the above expression.

= 133.334

[tex]\approx[/tex] 133

So, she can cut 133 ribbons from 20 meters long ribbon.

Answer:

10.16% probability that at most 6 trains will pass his house in a 12-hour time period

Step-by-step explanation:

We are dealing with the mean during a period of time, so we use the Poisson distribution to solve this question.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

In which

x is the number of sucesses

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

Colby has noticed that 21 trains pass by his house daily (24 hours)

We are working with 12 hour periods(half of 24), so [tex]\mu = \frac{21}{2} = 10.5[/tex]

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

What is the probability that at most 6 trains will pass his house in a 12-hour time period

[tex]P(X \leq 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)[/tex]

So

[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]

[tex]P(X = 0) = \frac{e^{-10.5}*(10.5)^{0}}{(0)!} = 0[/tex]

[tex]P(X = 1) = \frac{e^{-10.5}*(10.5)^{1}}{(1)!} = 0.0003[/tex]

[tex]P(X = 2) = \frac{e^{-10.5}*(10.5)^{2}}{(2)!} = 0.0015[/tex]

[tex]P(X = 3) = \frac{e^{-10.5}*(10.5)^{3}}{(3)!} = 0.0053[/tex]

[tex]P(X = 4) = \frac{e^{-10.5}*(10.5)^{4}}{(4)!} = 0.0139[/tex]

[tex]P(X = 5) = \frac{e^{-10.5}*(10.5)^{5}}{(5)!} = 0.0293[/tex]

[tex]P(X = 6) = \frac{e^{-10.5}*(10.5)^{6}}{(6)!} = 0.0513[/tex]

[tex]P(X \leq 6) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) = 0 + 0.0003 + 0.0015 + 0.0053 + 0.0139 + 0.0293 + 0.0513 = 0.1016[/tex]
