Answer:
Find "f(6)" __-8__
Find x when "f(x)=2" __x=1__
Step-by-step explanation:
For the first part, we will substitute 6 into the f(x) to get "-2(6)+4" When simplified further, you get "-12+4" which is "-8"
For the second part we will substitute the two as the answer of f(x) "-2x+4=2" Simplifying this further we get "-2x=-2" This means that x=1
X-y=4

Step-by-step explanation:
The probability of dry weather (D) = 1⁄2, rain (R) = 1⁄3 and snow (S) = 1⁄6
If it is dry the probability that someone will arrive on time is 4
/5.
If it rains the probability that someone will arrive on time is 2
/5.
If it snows the probability that someone will arrive on time is 1
/10.
Calculate the probability that somebody is late.
=============================================================
Explanation:
Define the following events
D = weather is dryR = weather is rainyS = weather is snowyL = person is lateT = person is on timeWe are given the following probabilities
P(D) = 1/2P(R) = 1/3P(S) = 1/6Then we're further told that "if it is dry, then the probability someone will arrive on time is 4/5". We can condense that into the notation
P(T given D) = 4/5
The "given D" means that we know 100% that event D has occurred. So we're seeing how event T behaves because of D occurring. In other words P(T given D) is the same as saying "What is P(T) when we know D has happened?"
-------------------------
The instructions also mention that "If it rains, the probability someone is on time is 2/5" tells us we have the notation
P(T given R) = 2/5
And also, the probability someone is on time if it is snowy is
P(T given S) = 1/10
due to it saying "If it snows, the probability that someone will arrive on time is 1/10".
-------------------------
To recap so far, your teacher told you these three conditional probabilities
P(T given D) = 4/5P(T given R) = 2/5P(T given S) = 1/10They are conditional due to the "given" as part of the probability. They depend on the given event happening.
Subtract each fraction from 1 and we end up with these complementary probabilities
P(L given D) = 1/5P(L given R) = 3/5P(L given S) = 9/10I'm using the idea that P(A)+P(B) = 1, where A and B are complementary events. One or the other event must happen. Either you are on time, or you are late.
---------------------------
Recall the conditional probability formula is
P(A given B) = P(A and B)/P(B)
which rearranges to
P(A and B) = P(A given B)*P(B)
We'll use this idea to get the following
P(L and D) = P(L given D)*P(D) = (1/5)*(1/2) = 1/10P(L and R) = P(L given R)*P(R) = (3/5)*(1/3) = 1/5P(L and S) = P(L given S)*P(S) = (9/10)*(1/6) = 3/20This means,
P(L) = P(L and D) + P(L and R) + P(L and S) ..... law of total probability
P(L) = 1/10 + 1/5 + 3/20
P(L) = 2/20 + 4/20 + 3/20
P(L) = (2+4+3)/20
P(L) = 9/20 is the probability someone is late

Answer:
y -10 = 1/8(x +8)
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
You have m = 1/8, and (h, k) = (-8, 10).
Putting those numbers in the form gives ...
y -10 = 1/8(x -(-8))
You can simplify the double minus sign so you have ...
y -10 = 1/8(x +8)

In hopes of encouraging healthier snacks at school, Janice brought in a tray 1 point
of carrot sticks and apple slices to share. She brought 76 snacks in all. 19 of
the snacks were carrot sticks. What percentage of the snacks were carrot
sticks?
Answer:
57%
Step-by-step explanation: Well, subtract 76 - 19 = 57. 57 of 100 = 57/100
57/100 = 57%

The evening low temperature in New York in the month of February was -7°F. The following day, the
temperature rose to a high of 25°F. What was the change in temperature that day?
Answer:
32°F
Step-by-step explanation:
Given that,
The low temperature in New York in the month of February was -7°F. The following day, the the temperature rose to a high of 25°F.
We need to find the change in temperature that day.
Change = final temperature - initial temperatur
Change = 25°F - (-7°F)
= 25 +7
= 32°F
so, the required change in temperature is 32°F.

Carlos needs 2/3 cups of raisins to make one batch of oatmeal bars. How many cups of raisins does Carlos need to makes batches of oatmeal bars? Select the correct answer.
Answer: 2²/₃ cups of raisins.
Step-by-step explanation:
Question wants to know the number of cups needed for 4 batches of oatmeal bars.
Each batch needs 2/3 cups of raisins to make.
If there are 4 batches to be made therefore, one must multiple the 2/3 cups to make one batch by 4 to find out the number needed to make 4 batches.
= 2/3 * 4
= 8/3
= 2²/₃ cups of raisins.
sarah started the school year with 14 drawings in her notebook and draws 5 more each day. whats the linear equation?
Answer:
y = 5x + 14
Step-by-step explanation:
Let x = number of day and y = number of drawings.
She draws 5 drawings per day, so in x days, she draws 5x drawings.
She started with 14 drawings, so the total number of drawings in any day, x, is
5x + 14.
The equation is
y = 5x + 14
