Five years after 650 high school seniors graduated, 400 had a college degree and 310 were married. Half of the students with a c

DedPeter [7]

Answer:

The probability that a student has a college degree or is not married is 0.8308.

Step-by-step explanation:

The information provided is:

Total number of high school seniors (N) = 650.

Number of seniors with a college degree (n (C)) = 400.

Number of seniors who were married, (n (M)) = 310.

Consider the Venn diagram below.

The probability of an event, say E, is the ratio of the favorable outcomes of E to the total number of outcomes of the experiment.

That is,

$P(E)=\frac{n(E)}{N}$

Here,

n (E) = favorable outcomes of E

N = total number of outcomes of the experiment.

The probability of the union of two events is:

$P(A\cup B)=P(A)+P(B)-P(A\cap B)=\frac{n(A)+n(B)-n(A\cap B)}{N}$

Compute the probability that a student has a college degree or is not married as follows:

$P(C\cup M^{c})=\frac{n(C)+n(M^{c})-n(C\cap M^{c})}{N}$

From the Venn diagram:

n (C) = 400

n ( $M^{c}$ ) = N - n (M) = 650 - 310 = 340

n (C ∩ $M^{c}$ ) = 200

The value of P (C ∪ $M^{c}$ ) is:

$P(C\cup M^{c})=\frac{n(C)+n(M^{c})-n(C\cap M^{c})}{N}=\frac{400+340-200}{650}=0.83077\approx0.8308$

Thus, the probability that a student has a college degree or is not married is 0.8308.

Which statensent is true about the coordinates of points A and 8?

Aleks04 [339]

$\frac{y}{x}$ of point B is equal to $\frac{y}{x}$ of point A. Correct option A).

Step-by-step explanation:

Here we have , a straight line in the graph between x-axis & y-axis . There are two points given here, A and B which lie in same line . Equation of line :

$y = \frac{3}{4}x$ , passing through origin . General equation of a line is :

$y = mx+c$ , where m = slope of line , c = x intercept , comparing this equation to to equation of line given in graph we get that m = 3/4 & c =0.

Useful info from here is slope = 3/4 . We know that slope = tan(theta) i.e.

⇒ $slope = tanx\\$

⇒ $tanx = \frac{Perpendicular}{base}$

⇒ $tanx = \frac{y}{x}$

⇒ $slope = \frac{y}{x}$

⇒ $\frac{y}{x} =\frac{3}{4}$ , which is constant i.e. ratio of y over x is a constant .Hence , $\frac{y}{x}$ of point B is equal to $\frac{y}{x}$ of point A. Correct option A).

What 5767 divided by 10,000

aliya0001 [1]

5767 ÷ 10,000 = 0.5767
An easier way is to count the zeros in the 10,000 and start on the right and move that many places then place a decimal in the spot you end at.
In this case, we have four zeros so we will start on the right moving to the left four times passing 7 would make it once. passing the 6 would make it twice, then passing the 7 would make it three times and passing 5 would make it four times. Now that we passed it four times We can put a decimal point. " . "
So it would be 0.5767
hope this helped!
