How many received D's and F's??

Answer: If in a prior study, a sample of 200 people showed that 40 traveled overseas last year, then n= 385

If no estimate of the sample proportion is available , then n= 601

Step-by-step explanation:

Let p be the prior population proportion of people who traveled overseas last year.

If p is known, then required sample size = [tex]n=p(1-p)(\dfrac{z^*}{E})^2[/tex]

z-value for 95% confidence = 1.96

E = 0.04  (given)

[tex]p=\dfrac{40}{200}=0.2[/tex]

[tex]n=0.2(1-0.2)(\dfrac{1.96}{0.04})^2=384.16\approx385[/tex]

Required sample size = 385

If p is unknown, then required sample size = [tex]n=0.25(\dfrac{z^*}{E})^2[/tex]

, where E = Margin of error , z* =critical z-value.

z-value for 95% confidence = 1.96

E = 0.04  (given)

So, [tex]n=0.25(\dfrac{1.96}{0.04})^2=600.25\approx601[/tex]

Required  sample size = 601.

Answer:

But Mars has no magnetosphere, and its atmosphere is over 100 times thinner than Earth's atmosphere. The trip to Mars and the stay on Mars will mean extended radiation exposure. Astronauts will need special habitats, suits, and machines that will protect them from radiation, which otherwise could cause cancer.

Answer: $25.46

Step-by-step explanation:

Year 1 FCFE = 1.8 * (1 + 10%) = $1.98

Year 2 FCFE = 1.98 * 1.1 = $2.18

Year 3 FCFE = 2.178 * 1.1 = $2.40

Year 4 FCFE = 2.3958 * 1.05 = $2.52

Year 5 FCFE= 2.51559 * 1.05 = ‭2.64

Terminal Value = (2.64 * 1.03) / (12% - 3%)

= $30.21

Now discount all these cashflows to find the value:

= (1.98 / 1.12) + (2.18 / 1.12²) + (2.40 / 1.12³) + (2.52 / 1.12⁴) + (2.64 / 1.12⁵) + (30.21 / 1.12⁵)

= $25.46

Answer:

Since the annual profit for the FIRST YEAR is $322,000 and it increases 21% every year for 26 years, you do so to find the answer to the question.

Step-by-step explanation:

21% per year

26 years

21 x 26 = 546

Now you have to find 546% of 322,000 and add that to 322,000.

546% of 322,000 is 1,758,120.

Answer:

$216,265,829

Step-by-step explanation:

To find the sum of a geometric series we use the following equation

[tex]a*\frac{1-r^n}{1-r}[/tex]

we have

[tex]322000*\frac{1-1.21^{26}}{1-1.21}\\\\322000*671.633=216265829[/tex]

Convert 0.8km to hours and minutes

One of the condition for a successful conversion is that: only units of the same metric can be converted.

i.e.

Meters can be converted to feet (they both measure distance)

Days can be converted to years (they both measure time)

Pounds can be converted to grams (they both measure weight)

But in the given question, you attempt to convert from distance to time.

This is not possible, because time and distance are different measurements

Answer: 20-10

Step-by-step explanation: 486-466 is 20. Half of 20 is 10. Any expression that equals ten is 1/2 as large as 486-466.

The expression is 1/2 as large as 486-466 is with the data 10.

Fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Let us understand this concept using an example. The following figure shows a pizza that is divided into 8 equal parts. Now, if we want to express one selected part of the pizza, we can express it as 1/8 which shows that out of 8 equal parts, we are referring to 1 part.

Given:

Class = 486 - 466

We have given a class whose upper limit = 486

and, lower limit = 466

the range or difference between class

=486 - 466

=20

Thus, the 1/2 of range is 10.

Hence, expression is 1/2 as large as 486-466 is with the data 10.

Answer:now you can give other guy brainliest.

Step-by-step explanation:

The graph of function g is graph Z because the graph of function g is the result of a horizontal compression applied to the graph of function f

Function f(x) is given as:

[tex]f(x) = (\frac 12)^x[/tex]

Function g(x) is given as:

g(x) = f(kx)

The above represents a horizontal compression of function f(x) to form function g(x)

The graph that represents a horizontal compression is graph Z

Hence, the graph of function g is graph Z
