Step-by-step explanation:

Brainliest pls

Answer 2

Answer: y = mx + b

y=-3  x=0 and m=2/5

-3 = (2/5)0 + b

Since 2/5(0) is 0, b must be -3

Step-by-step explanation: Since you know the slope and you know one point, all you have to do is plug the slope and the coordinates into the slope-intercept form and solve for b. You can check your answer by finding another point on the line and verifying that the equation works for that point, as well. Add the slope to the given point and you get ( 5 , -1 )

-1 = (2/5)5 - 3

-1 = 2 - 3 -1 = -1 So you know your answer is correct

Evaluate the expression.
1/7 divided by 2/5 - 1/7

Answers

Answer:

3/14

Step-by-step explanation:

In order to divide fractions, you'll have to find the recriprocal of 2/5. That is 5/2. So do 1/7 x 5/2 = 5/14.

So now find 5/14 - 1/7.

1/7 converted to a denominator of 14 is 2/14.

So we have 5/14-2/14 = 3/14. That is your answer.

The first thing that we should do is turn this into a mathematical formula.

[tex]\frac{1}{7} / (\frac{2}{5} -\frac{1}{7} ) = \frac{1}{7} /(\frac{9}{35} )[/tex] .

This is more generally written as

[tex]7(\frac{9}{35}) = \frac{9}{5}[/tex]

So, our answer is 9/5 or 1.8

Eight hundred fifty two thousand, six hundred seventy four and thirty five hundredths in numbers​

Answers

Answer:

Number = 857674.35

Step-by-step explanation:

Translating the word problem into a numerical format;

Eight hundred and fifty two thousand = 852,000

Six hundred and seventy four = 674

Thirty five hundredths = 35/100 = 0.35

Now, we would add all of the values together.

Number = 852,000 + 674 + 0.35

Number = 857674.35

x/9=x/10-4

Answers

start by getting like terms to one side.
x/9 - x/10 = -4
now make the fractions have a common denominator so that you can subtract
10x/90 - 9x/90 = -4
now simplify
x/90 = -4
now multiply each side by 90 to get rid of the fraction
x = -360
to check, just plug in the value of x into your original equation
it should come out to
-40 = -40

Answer:

x = -360

Step-by-step explanation:

x/9 = x/10 - 4

=> x/9 - x/10 = -4

=> x/10 - x/9 = 4

=> 9x/90 - 10x/90 = 4

=> -x/90 = 4

=> -x = 90(4)

=> x = -360

Suppose a university is divided into three campuses: the Main campus, the Downtown campus, and the Bay Area campus. The Main campus has 60% of the university's students, the Downtown campus has 25%, and the Bay Area has the rest. At the Main campus, 12% of the students are statistics majors. At the Downtown campus, 4% of the students are statistics majors. Finally, at the Bay Area campus, 1% of the students are statistics majors.

Required:
a. What proportion of students at the university are statistics majors?
b. Of all statistics majors at the university, what proportion are at the Main campus?

Answers

Answer:

a) 0.0835 = 8.35% of students at the university are statistics majors

b) 0.8623 = 86.23% are at the Main campus

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

This is used for item b.

a. What proportion of students at the university are statistics majors?

12% of 60%(At the main campus).

4% of 25%(Downtown campus).

The rest is 100 - 60 + 25) = 15%.

1% of 15%(Bay Area Campus). Si

[tex]p = 0.12*0.6 + 0.04*0.25 + 0.01*0.15 = 0.0835[/tex]

0.0835 = 8.35% of students at the university are statistics majors.

b. Of all statistics majors at the university, what proportion are at the Main campus?

Using conditional probability to find the percentage.

Event A: Statistics majors, so [tex]P(A) = 0.0835[/tex]

Event B: Main Campus

Intersection of A and B:

12% of 60%. So

[tex]P(A \cap B) = 0.12*0.6 = 0.072[/tex]

Percentage:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.072}{0.0835} = 0.8623[/tex]

0.8623 = 86.23% are at the Main campus

Answer:

Read Explanation

Step-by-step explanation:

Hello I think I can help.

Lets go over A then work on B to see if me walking through it can help you understand better.

Lets use some real world stuff. Say that the big long rectangle with the 3 and the x in it is a big truck, driving down the road.

Now inside that truck we have a 3 and a X as it shows in the picture. And then on the outside of the truck it shows what we have total inside the truck which is 15.

Now 3 + x may not sound equal to 15 but its math and if you see the = sign between two things they are equal no matter how weird it may seems.

So inside the truck, the 3 + x is equal to the outside of the truck saying that inside it is 15.

Lets move onto the B and do the same thing using the truck.

Now inside the truck it is saying 3 multiplied by x this time. On the outside it is saying there is a total of 15 just like before.

It looks to me you don't even have to solve it as the model seems to already be solved. But lets explain it.

Just like the problem says, (15 = 3 times x) you can see the 3 times x in the truck by the 3 separate x's inside the truck. And on the outside you can see the 15, which is the total amount inside the truck. And we know this is true because in the equation it says 15 = 3 times x.

I am not sure if you have to solve these but we can go over that real quick as well since it is very simple.

To find what x is in these equations all you want to do is take the outside of the truck (which is 15) and divide it by the number we know (3), not the variable (which is x).

So if we do this :

(The outside of the truck or the one number on its own)

15

(Divide it by the other number we know of inside the truck, not the letter/variable)

3

And we get :

15/3 = 5

x = 5

And that is our answer and you can do the same thing to part A.

You can also check to see if you're right by doing the same thing but backwards.

This means we use multiplication and go right to left (5 and 3) instead of left to right like we did last time (15 and 3).

If we multiply the 5 and the 3 we get 15 which is the other number in the equation and proves we are correct!

I do hope this helps.

Multiply both sides by 12

[tex] \frac{sin(x)}{12} \times 12 = \frac{sin(75)}{22} \times 12 [/tex]

[tex] sin(x) = \frac{sin(75) \times 12}{22} [/tex]
