By the way this problem is worded, he spends 75 minutes reading and cleaning, but there seems to be not enough information because the way it is worded, it means he has 75 minutes until he needs to GET READY, not play in the actual game. (40 + 35 = 75).

which of the following gives an equation of a line that passes through the point (6 over 5, -19 over 5) and is parallel to the l
victus00 [196]
One equation for this would be

y = \frac{41}{16} x-\frac{55}{8}

We start by finding the slope between the two points:

m=\frac{y_2-y_1}{x_2-x_1}=\frac{-12-\frac{-19}{5}}{-2-\frac{6}{5}}
\\
\\=(-12+\frac{19}{5}) \div (-2-\frac{6}{5})
\\
\\=(\frac{-60}{5}+\frac{19}{5}) \div (\frac{-10}{5}-\frac{6}{5})
\\
\\=\frac{-41}{5} \div \frac{-16}{5}=\frac{-41}{5} \times \frac{-5}{16}=\frac{41}{16}

A line parallel to this one will have the same slope.  We will use point-slope form to write our equation:

y-y_1=m(x-x_1)
\\
\\y-\frac{-19}{5}=\frac{41}{16}(x-\frac{6}{5})
\\
\\y+\frac{19}{5}=\frac{41}{16}x- \frac{41}{16} \times \frac{6}{5}
\\
\\y+\frac{19}{5}=\frac{41}{16}x-\frac{246}{80}
\\
\\y+\frac{304}{80}=\frac{41}{16}x-\frac{246}{80}
\\
\\y=\frac{41}{16}x-\frac{246}{80}-\frac{304}{80}
\\
\\y=\frac{41}{16}x-\frac{550}{80}
\\
\\y=\frac{41}{16}x-\frac{55}{8}

The local water slides have 100 employees, of which 30% are temporary. How many temporary employees are there?
Ugo [173]

Answer:

There are 30 temporary employees

Step-by-step explanation:

<em>To find </em><em>x% of quantity A</em><em>, multiply x% by A after change x% to the normal number by divide it by 100 ⇒ </em><em>(x ÷ 100) × A</em>

Let us use this rule to solve the question

∵ The local water slides have 100 employees

∵ 30% of them are temporary

∴ The number of temporary employees = 30% × 100

∵ 30% = 30 ÷ 100 = 0.30

∴ The number of temporary employees = 0.30 × 100

∴ The number of temporary employees = 30

∴ There are 30 temporary employees

When someone buys a ticket for an airline​ flight, there is a 0.098 probability that the person will not show up for the flight.
DedPeter [7]

Answer:

Step-by-step explanation:

Probability that a person will not show up is,

P(person not show up)=0.098.

Probability that they will show up is

1-0.098=0.902

P(person will show up)=0.902

Jet passenger seat=18.

a. But is it wise to book 20 passenger seat

If the flight attendant book 20.

We want to know the probability that the two person will not show up.

The probability that the 2 person  will not show up out of the 20 is given as

Using binomial distribution

Check attachment for formulas.

P(2 not showing up) =

20C2 • 0.098² • 0.902^20=0.2319

Which is 23.19% that the 2 person  will not show up.

b. But is it wise to book 24 passengers for 22 jet seat.

The probability that the 2 will not show up out of the 24 is given as

Using binomial distribution

P(2 not showing up) =

24C2 • 0.098²• 0.902²²=0.2741

Which is 27.41% that the four person will not show up.

c. Probability of no enough seat

For 20 passengers and 18seats on jet

1-0.2319=0.7631.

For 24 passengers and 20 seats on jet

1-27.41=0.7259.

Then,  It is not a wise decision because the probability that there are not enough seats on the jet is 0.7259 (72.59%). So, overbooking is an unlikely event.
