Answer:

Step-by-step explanation:

two points on the line are (-2,0) and (0,4)

slope=(y2-y1)/(x2-x1)=(4-0)/(0-(-2))=4/2=2

eq. of line is y-0=2(x-(-2))

y=2(x+2)

y=2x+4

There are a total of 12 cars and bicycles in a path. There are 40 wheels in total If x is the number of cars what is x-4?

Ahat [919]

Wouldn’t it be 8? I’m not math genius but 12 is the total of cars and is also x. So it would be 12-4 which is 8?

Answer:

5 is a coefficient

3y+13 is the factor

-1 is a constant

Step-by-step explanation:

We have given an expression to complete the statement:

In the first term 5 is a coefficient of x.

A coefficient is a number multiplied by a variable.

In the second term, 3y+13 is the factor

It can be multiplied by 8 to get an extended answer

In the third term -1 is a constant

A constant is a number that does not change

What's the solution set for the inequality x^2-2x<8?

Oliga [24]

$x^2-2x$

So, the numbers to base your solution set on are -2 and 4 (the numbers that the equation equal to 0)

Then, you plug in 3 numbers to the equation: a number less than -2, a number between -2 and 4, and a number greater than 4. They represent the three sections of the number line created by the points -2 and 4. So, our numbers will be -3, 0, and 5:

$(x-4)(x+2)$

7<0 is incorrect, so the section of the number line less than -2 does not work.

$(x-4)(x+2)$

-8<0 is correct, so the section of the number line between -2 and 4 works.

$(x-4)(x+2)$

7<0 is incorrect, so the section of the number line above 4 does not work.

So, only the section between -2 and 4 works. However, the problem is a "less than" problem, not a "less than or equal to" problem, so -2 and 4 are not included in the solution set. That gives you the answer:

(-2, 4) (NOT BRACKETS because -2 and 4 are not included)

The given two-way table shows the number of passengers, by type, on the Ferris wheel at an amusement part for its first two runs

zzz [600]

The two-way table is an illustration of probability, and the value of P(Adult|Second run) is 0.600

<h3>How to determine the probability?</h3>

The probability to calculate is given as: P(Adult|Second run)

This means:

The probability that an Adult is selected given that the adult runs the second run

The formula to solve this is:

P(Adult|Second run) = n(Adult and Second run)/n(Second run)

From the table, we have:

n(Adult and Second run) = 219

n(Second run) = 365

So, we have:

P(Adult|Second run) = 219/365

Evaluate

P(Adult|Second run) = 0.600

Hence, the value of P(Adult|Second run) is 0.600
