Answer:

The probability that a randomly selected resident of the Gold dorm is a senior is 0.1562

Step-by-step explanation:

The given percentage of each class of student is presented as follows;

Priority A (seniors) = 22%, ∴ P(s) = 0.22

Priority B (juniors) = 29%, ∴ P(j) = 0.29

Priority C (freshmen and sophomores) = (100 - 22 - 29)% = 49%, ∴ P(fs) = 0.49

The percentage of the seniors that elect to live at the Gold dorm, = 71%, ∴ P(sG) = 0.71

The percentage of the juniors that live at the Gold dorm = 19%, ∴ P(jG) = 0.19

The percentage of the freshmen and sophomores that live in the Gold dorm = 5%, ∴ P(fsG) = 0.05

The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = P(s) × P(sG)

∴ P(s∩sG) = 0.22 × 0.71 = 0.1562

Therefore;

The probability that a randomly selected resident of the Gold dorm is a senior = P(s∩sG) = 0.1562.

Answer:

Speed = 7520 km/h

Step-by-step explanation:

Given the following data;

Distance = 22,200,000 km.

Time = 1230 Earth days

To find the average speed of the planet;

First of all, we would have to convert the time in Earth days to hours;

1 Earth day = 24 hours

1230 Earth day = x

Cross-multiplying, we have;

x = 1230 * 24

x = 29520 hours

Therefore, time = 29520 hours

Substituting into the formula, we have;

Speed = 22200000/29520

Speed = 7520.325 km/h

To 3 significant figures;

Speed = 7520 km/h

Answer:

30 years and a half

Step-by-step explanation:

well let's just say 3.5k x hmm 2? at an estimate and that will get us to 7000.. so in order to get to 7000 we have to wait 15 years which is 30 years and a half. From Xthermyx. A brainly user.

It would take 22.7 years for the value of the account to reach $7,700.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Since the money in the account is doubling every 15 years.

The following equation is used to find the time it takes to reach a certain value:

t = (ln(P/F))/(ln(1+r))

where:

P = the initial investment amount

F = the future value we want to reach

r = the growth rate per period

ln = natural logarithm

t = the number of years it takes to reach F

P = $3,500

F = $7,700

r = ln(2)/15 (since the money is doubling every 15 years).

Plugging these values into the equation.

t = (ln(3500/7700)) / (ln(1+ln(2)/15))

t = ln (5/11) / ln (1 + 0.30/15)

t = 22.7

Therefore,

It would take 22.7 years for the value of the account to reach $7,700.

Answer:

each interior angle = 150°

Step-by-step explanation:

(N x 180°) - 360° = the sum of interior angles

where N = the number of sides

(12 x 180°) - 360° = 1800°

Since it is a regular polygon, all 12 angles are equal:

1800°/12 = 150°

Answer:

FV= $70,887.15

Step-by-step explanation:

First, we need to calculate the future value of the $130 deposit for 5 years:

FV= {A*[(1+i)^n-1]}/i

A= monthly deposit= $130

i= 0.08/12= 0.0067

n= 5*12= 60 months

FV= {130*[(1.0067^60) - 1]} / 0.0067

FV= $9,561.96

Now, using the following formula, the future value of the investment after 25 years:

FV= PV*(1 + i)^n

n= 25*12= 300

FV= 9,561.96*(1.0067^300)

FV= $70,887.15

Answer:

Acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Step-by-step explanation:

Given that,

Initial speed, u = 0

Final speed, v = 9 km/h = 2.5 m/s

Time, t = 5 seconds

We need to find the acceleration and the displacement covered in that time. Acceleration = rate of change of velocity

So,

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.5-0}{5}\\\\a=0.5\ m/s^2[/tex]

Distance d can be calculated using third equation of motion.

[tex]d=\dfrac{v^2-u^2}{2a}\\\\d=\dfrac{2.5^2-0^2}{2\times 0.5}\\\\d=6.25\ m[/tex]

So, acceleration is 0.5 m/s² and the distance covered is 6.25 m.

Answer and Step-by-step explanation:

To find the surface area, we have to find the area of all the faces of the shape, then add them together. We also only use the exposed faces, or the faces on the outside, not the inside.

Lets start with the rectangular prismed shape.

We have two faces with sides of 4 and 5, two faces with sides 16 and 4, and 1 side with 16 and 5.

Rectangles:

4 × 5 = 20

4 × 5 = 20

4 × 16 = 64

4 × 16 = 64

5 × 16 = 80

Now, let's do the triangles up top. There will essentially be 4 triangles, because we split them in half to find the area.

They have side lengths of 6 and 8.

Triangles:

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

6 × 8 = 48

Now, we have to the two rectangles up top.

They have side lengths of 10 and 4.

Top Rectangles:

10 × 4 = 40

10 × 4 = 40

Now, we add them all together.

20 + 20 + 64 + 64 + 80 + 48 + 48 + 48 + 48 + 40 + 40 =

40 + 208 + 192 + 80 =

520.

Answer:

16.5

Step-by-step explanation:

Find the value represented by a z-score of 2.403, given µ=63 and σ=4.25. Round your answer to one decimal place.

The z score formula =

z = (x-μ)/σ, where

x is the raw score = ?

μ is the population mean = 63

σ is the population standard deviation = 4.25

z = 2.403

Hence,

2.403 = (x - 63)/4.25

Cross Multiply

2.403 × 4.25 = x - 6.3

10.21275 = x - 6.3

Collect like terms

10.21275 + 6.3 = x

x = 16.51275

Approximately to 1 decimal place the value = 16.5
