About 7% of the population has a particular genetic mutation. 400 people are randomly selected. Find the standard deviation for the number of people with the genetic mutation in such groups of 400.

Answers

Answer:

5.10 people

Step-by-step explanation:

Calculation to Find the standard deviation for the number of people with the genetic mutation

Using this formula

Standard deviation = √ ( n * p * q)

Where,

n = 400

p = .07

q = 100%-7% = 93% or .93

Let plug in the formula

Standard deviation =√400*07*.93

Standard deviation =√26.04

Standard deviation = 5.10 people

Therefore the standard deviation for the number of people with the genetic mutation is 5.10 people.

Answers

Answer:

The answer is B.

Step-by-step explanation:

Please refer to the attachment (ignore the horrible drawing, thank you).

Let the distance from P to T be red. The length of the red distance is x radians.

T’ is π-x. Thus, it is the red distance subtracted from the purple distance.

So, T’ is the reflection of T across the y-axis.

Therefore, we can simply multiply the x-coordinate of T to get T’.

T is (3/5, 4/5)

Then T’ must be (-3/5, 4/5).

Hence, our answer is B.

There were 130 faculty at a conference. If there were 18 more women than men attending, how many of each gender attended the conference?

Answers

Answer:

the number of men be 56

And, the number of women be 74

Step-by-step explanation:

The computation of the number of each genders attended the conference is shown below;

Let us assume the number of men be x

And, the number of women be y

Now the equations would be

x + y = 130 .............. (1)

And,

y = 18 + x ................ (2)

Now put the y value in the equation 1

x + 18 + x = 130

2x = 130 - 18

2x = 112

x = 56

Now the y is

= 18 + 56

= 74

So, the number of men be 56

And, the number of women be 74

The formula for calculating simple interest, I, is I = prt where p is the principle, r is the rate and t is the time. Solve for p.
1. I - rt
2. I + rt
3. I/rt
4. rt/I

Answers

I = prt
P = I/ rt
I believe

The solution of the formula for p is p = I/ rt which is divided by the principle p times r. which is the correct answer would be an option (C)

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

Given that the formula as:

⇒ I = prt

where I = Interest, P = principal,

R = rate and T = time is used to calculate the amount of simple interest earned.

⇒ I = prt

After getting P on one side, you must divide rt to get the letter p by itself.

⇒ I = prt

⇒ p = I/ rt

Hence, the correct answer would be option (C)

Answers

Answer:

y = 3

m = 0

b = (0, 3)

Step-by-step explanation:

To put it in slope intercept form, divide each side by 2:

2y = 6

y = 3

So, y = 3 is the equation in slope intercept form.

The slope is 0, since there is no x value in the equation.

The y-intercept is (0, 3) since the equation is just y = 3.

Divide by 2
Y=3

which term of the series 2187,729,243...is 1/9

Answers

Answer:

Step-by-step explanation:

Givens

a = 2187

r = 1/3

L = 1/9

what is n

Formula

L = a*r^(n-1)

1/9 = 2187 * (1/3)^(n-1)

1/(9 * 2187) = (1/3)^(n - 1)

1/19683 = (1/3)^(n - 1)

=================

You need to break 19683 down into its prime factors.

19683 = 3* 729

19683 = 3 * 3 * 243

19683 = 3 * 3 * 3 * 81

81 = 3^4 so there are 4 more threes in the breakdown.

19683 = 3 * 3 * 3 * 3 * 3 * 3 * 3

1/19683 = 1/(3)^(7-1)

1/9 is the 6th term in the series.

True. The principal is the amount loaned. If you are the person loaning the money to the bank (which is effectively how they make money), then they pay you back in the form of interest. The bank takes a share of that interest of course. They may have other fees as well.False. The compound interest depends on how frequently the money is compounded. Usually it's done monthly. Though your bank would likely say it somewhere in the fine print. It is only when annual compounding takes place is when statement #2 is true.True. If the item you're trying to buy is larger than what is in your account, then you'll be overdrawing your account. Your bank will likely charge an overdraft fee. So it's best to pay attention to your balance as much as possible. True. You can bank from your phone, computer, tablet or laptop and do so anywhere in the world. Of course you'll need access to the internet. Keep in mind that some banking services require in-person visits so not everything is done online. True.

An ATM is a machine that dispenses cash, and it accepts deposits as well (either cash or check; though it may depend on the specific machine). ATM stands for Automated Teller Machine. It basically is a robotic banker, hence the phrasing "automated teller". Coupled with online banking, ATMs help spread a bank's footprint and allow customers to truly bank from anywhere. False. Withdraw means to subtract from the balance. True. A deposit increases your balance because you are giving that money to the bank.False. A bank statement is a document that tells you how much you have in your account(s) at any given month. It also provides the amount of interest earned as well as various deposits and withdrawals made for that month.

Answer:

A The number of miles driven will always be greater than or equal to zero and cannot be less than zero.

Step-by-step explanation:

The domain of a function such as this is the set of values that realistically may be given as input to the function. We know of no way to ride a motorcycle a negative number of miles, so the domain must be non-negative numbers.

In real life, the domain is likely non-negative integers.
