In this case, we need to substitute n with 10.
So, it is like this: f(10) = 3(10) + 4
f(10) = 3(10) + 4
f(10) = 30 + 4
f(10) = 34
Rewrite the equation 6x – 9y = 12 in terms of y.
Answer:
Step-by-step explanation:
6x - 9y = 12
subtract 6x from both sides
-9y = 12 - 6x
divide both sides by -9
y = -4/3 + 2/3x
or
y = 2/3x - 4/3
The equation 6x – 9y = 12 written in terms of y is; y = (2/3)x - 4/3
We are required to write the equation 6x – 9y = 12 in terms of y.Rewriting the equation 6x – 9y = 12 in terms of y is as follows;
6x – 9y = 12 6x - 12 = 9yDivide through by 9 so that we have;
y = (2/3)x - 4/3

Find two consecutive even integers such that the sum of the smaller and 3 times the larger is 330
I am so stuck please any one help
Answer:
The 2 numbers = 81 and 83
Step-by-step explanation:
As, one number = x
The other, because it's an even number and consecutive = x + 2
So the larger numbef here is x + 2
And they are saying 3 times x + 2 plus x = 330
So let's solve!
3 times x + 2 = 3(x+2) = 3x + 6
So we will add it to x = (3x + 6) +(x) = 4x + 6
So they are saying the sum of them will be 330
So, 4x + 6 = 330
4x = 330 - 6
4x = 324
x = 324/4
x = 81
So x is the first number = 81
And the second is x + 2 = 81 + 2 = 83
So the 2 numbers are 81, 83
Lets check!
3 times the bigger number = 83 x 3 = 249
We will add it to 81 and we will get 330
So, 249 + 81 = 330
So the answer is right

In a standard 52-card deck, half of the cards are red and half are black. The 52 cards are divided evenly into 4 suits: spades, hearts, diamonds, and clubs. Each suit has three face cards (jack, queen, king), and an ace. Each suit also has 9 cards numbered from 2 to 10. 7.
Dawn draws 1 card, replaces it, and draws another card. Is it more likely that she draws 2 red cards or 2 face cards?
Answer:
It is more likely she draws 2 red cards
Step-by-step explanation:
Given that:
Number of red d cards in deck = 26
Number of face cards = 4 * 3 = 12 face cards
If two cards are drawn with replacement ;
Probability = (required outcome / Total possible outcomes)
P(1st card red) = 26 /52) = 1/2
P(2nd card red) = 26 /52 = 1/2
P(1st card red) * P(2nd card red)
1/2 * 1/2 = 1/4 = 0.25
P(1st card face card) = 12/52 = 3/13
P(2nd card, face card) = 12/52 = 3/13
P(1st card face card) * P(2nd card face card)
3/13 * 3 /13 = 9/169 = 0.053
0.25 > 0.053
It is more likely she draws 2 red cards

==========================================================
Explanation:
This is a 45-45-90 right triangle. Any triangle of this form is isosceles, where the two legs are the same length. In this case, m and n are those two legs. So m = n.
We can then apply the Pythagorean theorem to say
a^2 + b^2 = c^2
m^2 + n^2 = (9*sqrt(2))^2
m^2 + m^2 = 9^2*(sqrt(2))^2
2m^2 = 81*2
m^2 = (81*2)/2
m^2 = 81
m = sqrt(81)
m = 9
As a shortcut, the hypotenuse of a 45-45-90 triangle is equal to sqrt(2) times the length of either leg. If m is the length of the leg, then m*sqrt(2) is the length of the hypotenuse. So in a sense, we take this thought process backwards to go from a hypotenuse 9*sqrt(2) to a leg length of 9.
The manager of a symphony in a large city wants to investigate music preferences for adults and students in the city. Let pA represent the population proportion of adults who live in the city who prefer pop music. Let pS represent the population proportion of students who live in the city who prefer pop music. Random samples of 200 adults from the city and 200 students from the city will be selected. Which of the following is the best interpretation of P(pˆA−pˆS>0)≈0.022 ?
Answer:
Answer E
Step-by-step explanation
The statement gives a probability of approximately 0.022 for the difference in sample proportions, pˆA−pˆS, being greater than 0.
The interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
Given :
pA is the population proportion of adults.pS is the population proportion of students.The total number of adults is 200 and the total number of students is also 200.The following steps can be used in order to determine the best interpretation of the given expression:
Step 1 - According to the given data, pA is the population proportion of adults who live in the city who prefer pop music.
Step 2 - Also given that pS is the population proportion of students who live in the city who prefer pop music.
Step 3 - So, the interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
