20y+5x≤100  divide all terms by 5

4y+x≤20  subtract x from both sides

4y≤-x+20  divide both side by 4

y≤-0.25x+5

So just in simplest terms, the slope is slightly negative and it should be shaded under the line since y is less than the line...so it is the second graph.

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}

Need help with math ASAP (Please)
Scrat [10]
First you plot in the y-intercept of the equation. To find the y-intercept, substitute 0 into x. -3m will cancel our giving you y=5. x=0, y=5, the first ordered pair is (0,5). Now after you plot in the y-intercept, use your slope, which is -3, to graph the points of the equation. Starting from (0,5), move down 3 spaces on the y-axis (because it’s -3) and you’ll end up at (0,2). Next move over 1 ( all slopes with just a whole number moves on the x-axis 1 since the whole number divided by 1 doesn’t change the slope number) to the right because it’s a negative linear equation so it’ll go downward. After moving right, you’ll get (1,2). Do a couple more points starting from (1,2) then the 3rd point ABD and so on to get 3 or more points to be able to draw a linear line.
