Answer:

3 points

Step-by-step explanation:

if you do the vertical line check you can see that there are 3 lines with 2 points on one line vertically. for it to be a function it would need to only have one so you would need to remove one from each line.

Answer:

3 points

Step-by-step explanation:

If you do the vertical line test, there are 3 points that need to be removed, as there can only be 1 x value for every y value in order for it to be a function.

Kristen invests $5,000 in a bank. The bank pays 6.45% interest compounded semi-annually. How much money will she have after 2 ye

kupik [55]

Answer: $5,676.87

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:

A = P (1 + r/n) nt

Where:

A = Future value of investment (principal + interest)

P = Principal Amount

r = Nominal Interest Rate (decimal form, 6.45/100= 0.0645)

n= number of compounding periods in each year (2)

Replacing with the values given

A = 5,000 (1+ 0.0645/2)^ (2x2)

A = 5,000 (1.03225)^4

A = $5,676.87

Which value of x results in equal outputs for j(x) = 3x − 2 and b(x) = |x + 2|

diamong [38]

Answer:

Step-by-step explanation:

J(x)=b(x)

3x-2=|x+2|

3x-2=±(x+2)

when 3x-2=x+2

3x-x=2+2

2x=4

x=4/2=2

when 3x-2=-(x+2)

3x-2=-x-2

4x=-2+2=0

x=0

it is rejected as 0-2≠|0+2|

or -2=2

so x=2

A box contains 15 large marbles and 11 small marbles. Each marble is either green or white. 9 of the large marbles are green, an

melamori03 [73]

Answer:

The probability of selecting a small or white marble is 10/13

Step-by-step explanation:

The total number of marbles is 15 + 11 = 26 marbles

The probability that we want to calculate is if the marble selected is small or white.

So we need to find the number of small marbles as well as the number of white marbles

We can construct a table to see the distribution of the marbles. Please check the attachment for this.

From the table , we can see that there are 11 small marbles and a total of 9 white marbles

The probability of selecting a white marble is;

number of white marbles/total number of marbles = 9/26

The probability of selecting a small marble will be ;

number of small marbles/total number of marbles = 11/26

In probability, whenever we have or, we tend to add

So therefore, the probability of selecting a white or small marble = Probability of selecting a white marble + Probability of selecting a small marble

Mathematically, that would be 9/26 + 11/26 = 20/26

So the probability is 10/13
