F(-2) is the f(x) when x is -2. From the table, it is 1.

Answer:

Yeah, it tells you values from when x and y are both -2, so I don't know why you need us to tell you.

Step-by-step explanation:

If you meant to ask something else, the way to find an X value is

Y = -0.5555555555555556 X — 0.3333333333333335

Just plug in x, and you'll get Y.

A number r is more than 0 or less than or equal to ‐8

Butoxors [25]

Answer

-8 $\geq$ r > 0

Step-by-step explanation:

you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.

4) A line has a slope of -5 and passes through the point (2, 2). An equation for this line is

stich3 [128]

Answer:

$D: y= -5x+12$

Step-by-step explanation:

Since the slope is -5 is either C or D. Let's replace $x= 2$ in either to see what we get.

C: $-5(2)-2 = -12$ Nope.

D: $-5(2) +12 = 2$ Good!

Please explain what this means! (no math needs to be done as I got the answers but I don't understand the explanation...)

you can imagine this as a venn diagram. the "or" event would consist of everything in both sides and the middle of the venn diagram because you can choose form either event x <u>or</u> event y.

the "and" event would consist of everything in the middle of the venn diagram because you choice must be a part of both event x <u>and</u> event y.

the complement of an event is just everything that is not included in the event. for example, in a coin flip, the complement of heads is tails. in a dice roll, the complement of {1,2} is {3,4,5,6}

so if you come across these just think "either or" or "both and." and remember that the complement is everything excluding what is listed.

i apologize if this does not help, im not that great at explaining things

An 11-inch string is cut into 3 equal pieces. Which expression shows the length of each piece?

slega [8]

Sense this string would only be 11 (in), and we are cutting it into 3 pieces, this would show us that we would then be dividing the 11 (in) string into 3 pieces. The expression would be below.

$\boxed{11\div3}$

In a statistics class there are 18 juniors and 10 seniors; 6 of the seniors are females and 12 of the juniors are males. If a st

Natasha_Volkova [10]

Answer:

P(a junior or a senior)=1

Step-by-step explanation:

The formula of the probability is given by:

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

Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.

In this case, N is the total number of the students of statistics class.

N=18+10=28

The probability of the union of two mutually exclusive events is given by:

$P(AUB)=P(A)+P(B)$

Therefore:

P(a junior or a senior) =P(a junior)+P(a senior)

Because a student is a junior or a senior, not both.

n(a junior)=18

n(a senior)=10

P(a junior)=18/28

P(a senior) = 10/28

P(a junior or a senior) = 18/28 + 10/28

Solving the sum of the fractions:

P(a junior or a senior) = 28/28 = 1
