ANSWER THIS FOR 11 POINTS, what are the slope and y intercept of the function?
Butoxors [25]

Answer:

y intercept=4 and the slop is 1/3

Step-by-step explanation:

The y intercept is the point where the line intersects the y axis. As we can see the line is intecepting the y axis at point 0,4 or just 4. To find the slope from that point you need to go y places up or down and x places left or right-additionally the point has to be on that line. For example from point 0,4 which is our y-intercept if we go up 1 and over 3 to the right from that point then we get another point that's on the line.

-kinda hard to explain but hope this helps

In a statistics class of 13 sophomores, 12 juniors, and 8 seniors, 5 of whom are male sophomores, 6 of whom are female juniors,
8_murik_8 [283]

Answer:

\frac{20}{33}

Step-by-step explanation:

We are given that

Sophomores=13

Juniors=12

Seniors=8

Male sophomores=5

Female sophomores=6

Male seniors=4

We have to find the probability of randomly selecting a junior or  a senior.

Total persons=13+12+8=33

Let A=Seniors

B=Juniors

Probability,P(E)=\frac{number\;of\;favorable\;cases}{total\;number\;of cases}

Using the formula of probability

P(A)=\frac{8}{33}

P(B)=\frac{12}{33}

A\cap B=0

P(A\cap B)=0

P(A\cup B)=P(A)+P(B)-P(A\cap B)

P(A\cup B)=\frac{8}{33}+\frac{12}{33}

P(A\cup B)=\frac{8+12}{33}=\frac{20}{33}

Hence, the probability of selecting a junior or senior=\frac{20}{33}
