Nia solved the equation -1.98 = 5.2 v + 13.1. Her answer was v = -2.9. She is fairly confident about her answer, but wants to do

a quick check of her solution using estimation to make sure her answer is reasonable.
Which of the following shows a good check of her answer?

-2 = 5(-2) + 13
-1 = 5(-2) + 13
-3 = 5(-2) + 13
-2 = 5(-3) + 13

How do u write graphs in standard form?
Deffense [45]

Answer:

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.

Suppose an airport metal detector catches a person with metal 99% of the time. That is, it misses detecting a person with metal
frozen [14]

Answer:

The probability of missing the first metal-carrying person is P(x≤50)=0.395

Step-by-step explanation:

We define as success to: missing metal carrying detection.

p=0.01

P(x)=\frac{n!}{x!(n-x)!} p^x(1-p)^{n-x}

We look for the probability when all metal carring people is detected so x=0

P(x≤50)=1-P(x=0)=1 - 0.99^{50}=0.395
