Answer:

1. Yes it does. It's a function because it pass in the vertical line test, which tell us that if you can draw an vertical line through the graph and this line touches the graph in only one point, it is a function.

2. B. I and II only

3. A. y = 8/7 x +5

Suppose you want to get a loan for $ 5 , 000 at an interest rate of 5.3 % for 2 years to be paid back in 24 monthly installments

swat32

Answer:

monthly payment = $56.445

Step-by-step explanation:

given data

loan = $5000

interest rate r = 5.3 % = 0.053

time t = 2 year = 24 months

solution

we will use here amount of the monthly payments formula that is

monthly payment = principal × $\frac{r}{1+(1-r)^{-t}}$ ................1

put here value and we get

monthly payment = 5000 × $\frac{0.053}{1+(1-0.053)^{-24}}\\$

monthly payment = $56.445

at a particular high school, 42% of the students participate in sports and 25% of the students participate in drama. if 53% of t

baherus [9]

The probability that a student participates in both sports and drama is $0.14$ .

<h3>What is the formula for P(AUB), where A and B are any two events?</h3>

If $A$ and $B$ are any two events, then the probability of the joint event $(A\cup B)$ is given by the following formula: $P(A\cup B)=P(A)+P(B)-P(A\cap B)$

Given that 42% of the students participate in sports and 25% of the students participate in drama and 53% of the students participate in either sports or drama.

Suppose $S$ denotes that "a student participates in sports" and $D$ denotes that "a student participates in drama".
So, we have $P(S)=\frac{42}{100}=0.42$ , $P(D)=\frac{25}{100}=0.25$ , $P(S\cup D)=\frac{53}{100}=0.53$ .

We want to find the probability that a student participates in both sports and drama i.e., we want to find $P(S\cap D)$ .

By the above formula, we obtain:

$P(S\cup D)=P(S)+P(D)-P(S\cap D)\\\Longrightarrow P(S\cap D)=P(S)+P(D)-P(S\cup D)\\\Longrightarrow P(S\cap D)=0.42+0.25-0.53\\\therefore P(S\cap D)=0.14=\frac{14}{100}$

Therefore, the probability that a student participates in both sports and drama is $0.14$ .

A bag contains 6 red marbles, 2 white marbles, and 1 gray marble.You randomly pick out a marble,record its color,and put it back

Dominik [7]

You should expect 5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's 1/9 45 times, or 1/9(45).

$\frac{1}{9} * \frac{45}{1}$

1*45 is 45

9*1 is 9.

45/9 is 5.

Mark is solving the equation 4x2 + 2x = -9 using the quadratic formula.

Masteriza [31]

4x^2 + 2x = -9
4x^2 + 2x + 9 = 0

remember that the form of quadratic is ax^2 + bx + c = 0

so
a = 4
b = 2
c = 9
