An airline estimates that 90% of its eastbound flights arrive on time and 72% of its westbound flights arrive on time. This morning, 42% of the airline’s schedule is westbound flights. If a flight is chosen at random, what is the probability that the flight does not arrive on time? Write your answer as a percent rounded to the nearest tenth.

Answer:

[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]

So then the distance between the submarine and the airplace is 525 m

Step-by-step explanation:

For this case we know that the submarine is 150 m below the sea level and the airplane is 375 m above the sea level and we want to find the difference between the heights and we got:

[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]

So then the distance between the submarine and the airplace is 525 m

Answer:

6.1

Step-by-step explanation:

we will name the length in front of the angle , y :

tan(71°)≅2.904= y ÷2

⇒ y=  5.8

and we know that

c = [tex]\sqrt{2^{2} + y^{2} }[/tex]

then  

c = 6.14

and if we round it to the nearest tenth :

c = 6.1

Answer:

Step-by-step explanation:

Answer:

The (population) standard deviation is 26 miles or [tex] \\ \sigma = 26[/tex] miles.

Step-by-step explanation:

We can solve this question using the concept of z-score or standardized value, which is given by the formula:

[tex] \\ z = \frac{x - \mu}{\sigma}[/tex] [1]

Where

[tex] \\ z[/tex] is the z-score.

[tex] \\ x[/tex] is the raw score.

[tex] \\ \mu[/tex] is the population's mean.

[tex] \\ \sigma[/tex] is the population standard deviation.

Analyzing the question, we have the following data to solve this question:

Therefore, using all this information, we can determine the (population) standard deviation using formula [1].

Then, substituting each value in this formula:

[tex] \\ z = \frac{x - \mu}{\sigma}[/tex]

Solving it for [tex] \\ \sigma[/tex]

Multiplying each side of the formula by [tex] \\ \sigma[/tex]

[tex] \\ \sigma*z = (x - \mu) * \frac{\sigma}{\sigma}[/tex]

[tex] \\ \sigma*z = (x - \mu) * 1[/tex]

[tex] \\ \sigma*z = x - \mu[/tex]

Multiplying each side of the formula by [tex] \\ \frac{1}{z}[/tex]

[tex] \\ \frac{1}{z}*\sigma*z = \frac{1}{z}*(x - \mu)[/tex]

[tex] \\ \frac{z}{z}*\sigma = \frac{x - \mu}{z}[/tex]

[tex] \\ 1*\sigma = \frac{x - \mu}{z}[/tex]

[tex] \\ \sigma = \frac{x - \mu}{z}[/tex]

Then, this formula, solved for [tex] \\ \sigma[/tex], will permit us to find the value for the population standard deviation asked in the question.

[tex] \\ \sigma = \frac{431.8 - 450}{-0.7}[/tex]

[tex] \\ \sigma = \frac{-18.2}{-0.7}[/tex]

[tex] \\ \sigma = 26[/tex]

Thus, the (population) standard deviation is 26 miles or [tex] \\ \sigma = 26[/tex] miles.

Answer:

[tex] P(24< X<38)= P(X<38) -P(X<24)= F(38) -F(24)[/tex]

And replacing we got:

[tex] P(24< X<38)=\frac{38-20}{40-20}-\frac{24-20}{40-20}= 0.9-0.2= 0.7[/tex]

Step-by-step explanation:

We can define the random variable X as the thickness of a protective coating applied to a conductor designed to work in corrosive conditions. And the distribution for X is given by:

[tex] X \sim Unif (a = 20, b=40)[/tex]

And we want to find this probability:

[tex] P(24< X<38) [/tex]

And in order to find this probability we can use the cumulative distribution function given by:

[tex] F(x) = \frac{x-a}{b-a} , a\leq X \leq b[/tex]

And if we use this formula for the probability desired we have:

[tex] P(24< X<38)= P(X<38) -P(X<24)= F(38) -F(24)[/tex]

And replacing we got:

[tex] P(24< X<38)=\frac{38-20}{40-20}-\frac{24-20}{40-20}= 0.9-0.2= 0.7[/tex]

Answer:

She uses [tex]\frac{1}{12}[/tex] of the sheet of paper to make the flower.

Step-by-step explanation:

She cuts 1/2 of a piece of paper.

Of what was cut, she used 1/6 to make a piece.

What fraction of the sheet of paper does she use to make the flower?

A sixth of one half. So

[tex]\frac{1}{6}*\frac{1}{2} = \frac{1}{12}[/tex]

She uses [tex]\frac{1}{12}[/tex] of the sheet of paper to make the flower.

Answer:

16.06 ft

Step-by-step explanation:

The figure is attached below.

In triangle ACB:

[tex]tan(41)=\frac{x}{y} \\x=ytan(41)[/tex]

In triangle ADB:

[tex]tan(25)=\frac{x}{y+10} \\(y+10)tan(41)=x[/tex]

Therefore equating both equations gives:

[tex]ytan(41) = (y+10)tan(25)\\ytan(41) = ytan(25)+10tan(25)\\ytan(41)-ytan(25)=10tan(25)\\y(tan(41)-tan(25))=10tan(25)\\y=\frac{10tan(25)}{(tan(41)-tan(25)} =11.5715ft[/tex]

Therefore x = 11.5715*tan(41) = 10.06 ft

Answer:

No, she will earn 16.50/hr after the raise

Step-by-step explanation:

Catie's raise will be 15*0.10, which is $1.50

Caitie currently earns $15.00 an hour at her job, her boss is going to give her a 10% raise. she will earn 16.50/hr.

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Caitie currently earns $15.00 an hour at her job. Thanks to her hard work, her boss is going to give her a 10% raise. Caitie thinks that this means she will earn about $25.00 an hour.

10% of 15

= 15 × 0.10

= $1.50

The total amount will be = 15 + 1.50

We have been given that in ΔRST, s = 93 inches, ∠S=123° and ∠T=28°. We are asked to find the length of r to the nearest 10th of an inch.

We will use law of sines to solve for side r.

[tex]\frac{a}{\text{Sin}(a)}=\frac{b}{\text{Sin}(B)}=\frac{c}{\text{Sin}(C)}[/tex], where a, b and c are corresponding sides to angles A, B and C respectively.

Let us find measure of angle S using angle sum property of triangles.

[tex]\angle R+\angle S+\angle T=180^{\circ}[/tex]

[tex]\angle R+123^{\circ}+28^{\circ}=180^{\circ}[/tex]

[tex]\angle R+151^{\circ}=180^{\circ}[/tex]

[tex]\angle R+151^{\circ}-151^{\circ}=180^{\circ}-151^{\circ}[/tex]

[tex]\angle R=29^{\circ}[/tex]

[tex]\frac{r}{\text{sin}(R)}=\frac{s}{\text{sin}(S)}[/tex]

[tex]\frac{r}{\text{sin}(29^{\circ})}=\frac{93}{\text{sin}(123^{\circ})}[/tex]

[tex]\frac{r}{\text{sin}(29^{\circ})}\cdot \text{sin}(29^{\circ})=\frac{93}{\text{sin}(123^{\circ})}\cdot \text{sin}(29^{\circ})[/tex]

[tex]r=\frac{93}{0.838670567945}\cdot (0.484809620246)[/tex]

[tex]r=110.889786233799179\cdot (0.484809620246)[/tex]

[tex]r=53.7604351[/tex]

Upon rounding to nearest tenth, we will get:

[tex]r\approx 53.8[/tex]

Therefore, the length of r is approximately 53.8 inches.
