Look at the picture.

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

We have:

$b=-4$

$m=\dfrac{\Delta y}{\Delta x}\to m=\dfrac{+1}{+1}=1$

Substitute:

$y=1x-4=x-4$

Answer:

$5\sqrt{3}$

Step-by-step explanation:

$a^{2} +b^2=c^2\\11^2+x^2=14^2$

121+x^2=196

x^2=75

x= $\sqrt{75} \\5\sqrt{3} \\or 8.66$

statuscvo [17]

Answer-

Y=125,000 (1+.035)^10

Y=125,000 (1.035)^10

Y=125,000 (1.410598716) or 125,000 (1.41)

Y= $176324.85 or $176250

Answer:

0.0803 = 8.03% probability that the number who have a high school degree as their highest educational level is exactly 32.

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they have a high school degree as their highest educational level, or they do not. The probability of an adult having it is independent of any other adult. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

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