If you deposit $6000 into an account paying 8% annual interest compounded monthly, how much money will be in the account after 7

Leviafan [203]

Answer:

$10278

Step-by-step explanation:

Given data

P= $6000

R= 8%

T= 7 years

The compound interest formula is

A=P(1+r)^t

substitute

A=6000(1+0.08)^7

A=6000(1.08)^7

A=6000*1.713

A=$10278

Which best explains the relationship between lines a and b? They are skew and will never intersect. They are parallel and will n

r-ruslan [8.4K]

Answer:

They are skew and will never intersect.

Step-by-step explanation:

see attachment for the missing figure

Lines a and b are skew lines since they are not parallel and they do not intersect. The explanation that they don't intersect is on the grounds that each line is in a parallel plane. Parallel means heading off to the same direction but neither converging nor diverging.

Given: ABCD is a trapezoid with AB || DC. If m∠A = 125 and m∠B = 99, find m∠C/

Pavlova-9 [17]

Answer:

The measure of angle C is $81\°$

Step-by-step explanation:

we know that

If AB || DC

then

$m$ -----> supplementary angles by consecutive interior angles

and remember that the sum of the interior angles in a trapezoid is equal to 360 degrees

$m$

step 1

Find the measure of angle D

$m$

substitute the measure of angle A

$125\°+m$

$m$

step 2

Find the measure of angle C

$m$

substitute the values

$125\°+99\°+m$

$m$

The variance Var(x) for the binomial distribution is given by equation :

aliina [53]

Answer: d. np(1 - p).

Step-by-step explanation:

Let x be any binomial variable which represents the number of success such that $X\sim B(n, p)$ , where n is the sample size or the total number of trials and p is the probability of getting success in each trial .

Then, the mean E(x) and the variance Var(x) for the binomial distribution is given by equation :

$E(x)=\mu=np$

$Var (x)=\sigma^2=np(1-p)$

where n is the sample size or the total number of trials and p is the probability of getting success in each trial .

Therefore , the correct option is option d. np(1 - p) .
