Blake and Ned work for home remodeling business they are putting the final touches on a home they renovated. working alone Blake

stiks02 [169]

Answer:

3.6 hours

Step-by-step explanation:

Blake can do work in hours = 9

Blake can do a part of work in 1 hour = $\frac{1}{9}$

Ned can paint the same room in six hours.

Ned can do a part of work in 1 hour = $\frac{1}{6}$

They can do a part of work together in 1 hour = $\frac{1}{9}+\frac{1}{6}$

= $\frac{5}{18}$

Now they can do $\frac{5}{18}$ part of work in hour = 1

So, they can do whole work in hours = $\frac{1}{\frac{5}{18}}$

= $3.6$

Hence it will take 3.6 hours to paint the room if they work together.

a number cube from 1-6 is rolled 30 times and lands on an even number 18 times. what is the probability that it lands on an even

Amanda [17]

Answer:

0.50

Step-by-step explanation:

The chance is the same no matter what happens on each roll, the chance of it landing is always 50% because half the numbers on the dice are even (2,4,6).

How am I supposed to do this?

Arisa [49]

For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)

#9-Step by step

Q=25 $\pi$ h

divide 25 $\pi$ on both sides of the equation

Q/25 $\pi$ =h

h=Q/25 $\pi$

Since his can't be simplified any further this is your answer

#11. y=7m+6

First subtract 6 over to the other side

y-6=7m

then divide the 7 over

(y-6)/7=m

m=(y-6)/7

#13 A=(Z+7)3

Divide the three over to the other side of the equation

A/3=Z+7

Now the 7 is free to be subtracted from both sides

(A/3)-7=Z

#17. (2x/5)-9=6

First add 9 to both sides

2x/5=6+9

2x/5=15

Multiply both sides of the equation by 5

2x=5(15)

2x=75

Divide by 2

x=75/2

x=37.5

Jeannie is an experienced business traveler, often traveling back and forth from San Francisco to the East Coast several times p

lesya692 [45]

Answer:

The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.

Jeannie should leave her office 55 minutes early.

Step-by-step explanation:

Let X = time it requires Jeannie to catch her plane.

The random variable X is normally distributed, $N(46, 5)$ .

Compute the probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour as follows:

$P(X>60)=P(\frac{X-\mu}{\sigma} >\frac{60-46}{5} )\\=P(Z>2.8)\\=1-P(Z$

The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.

Now, it is provided that Jeannie has 96% chance of catching her flight if she reaches under x minutes.

That is, P (X < x) = 0.96.

Compute the value of x as follows:

$P(X$

**Use the z-table to compute the value of z.

The value of z is 1.751.

Compute the value of x as follows:

$z=\frac{x-46}{5}\\ 1.751=\frac{x-46}{5}\\x=46+(1.751\times5)\\=54.755\\\approx 55$

Thus, Jeannie should leave her office 55 minutes early.
