The answer is 0. the additive inverse of a negative number is the same number but positive. to find the sum means to add them together. for example take 2 and -2. 2 is the additive inverse of -2. if you add 2+-2 the answer comes out to 0

Question 11 . 2 p Brent is considering buying a new circular track for his model train. He estimates that the model's circumfere

neonofarm [45]

Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.

<h3>What is a circle? </h3>

A circle is the locus of a point, such that the distance from a fixed point (center) is always constant.

The circumference of a circle is given by:

Circumference = π * diameter

Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.

Steph makes 90 % 90%90, percent of the free throws she attempts. She is going to shoot 3 33 free throws. Assume that the results

zmey [24]

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

He makes 90% of the free throws, hence $p = 0.9$ .

He is going to shoot 3 free throws, hence $n = 3$ .

The probability that he makes exactly 1 is P(X = 1), hence:

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 1) = C_{3,1}.(0.9)^{1}.(0.1)^{2} = 0.027$

0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

they've invested to earn $20 in a savings account that offer 3% return on the investment the value of david's investment will be

Firlakuza [10]

I=PRT
P=present amount
R=rate
T=time
basically
20+interest is more than or equal to 400
20+I>400
minus 20 both sides
I>380

solve
P=20
R=3%=0.03
T=?
I=PRT
380<I=PRT
380<20(0.03)(T)
380<0.6T
divide both sides by 0.6
633.33333<T
633.33 years at least
