Answer:

Step-by-step explanation:

Use definition of conditional probability:

$P(A|B)=\dfrac{P(A\cap B)}{P(B)},$

where

A = the student is a freshman,

B = the student is a male

From the table,

$P(B)=\dfrac{4+6+2+2}{4+6+2+2+3+4+6+3}=\dfrac{14}{30}=\dfrac{7}{15}\\ \\P(A\cap B)=\dfrac{4}{4+6+2+2+3+4+6+3}=\dfrac{4}{30}=\dfrac{2}{15}$

So,

$P(A|B)=\dfrac{\frac{2}{15}}{\frac{7}{15}}=\dfrac{2}{7}\approx 0.29=29\%$

Give the slope of y- 4 = 5(x - 2) and a point on the line.

ValentinkaMS [17]

Answer:

<h2>B. The slope is 5 and (2, 4) is on the line.</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

We have the equation:

$y-4=5(x-2)$

Therefore

m = 5

(x₁, y₁) = (2, 4)

The Federal Insurance Contributions Act (FICA) is made up of two items, Social Security and Medicare taxes. For 2016, the Social Security tax rate is 6.2% on the first $118,500 wages paid. The Medicare tax rate is 1.45% on the first $200,000 and 2.35% above $200,000. Since the total earnings is only $110,700 which is not yet taxable. So there is no taxable earnings yet.
