Answer 1

Answer:

Part a) The graph in the attached figure

Part b) The units rate of change is 9

Step-by-step explanation:

we know that

A relationship between two variables, t, and d, represent a proportional variation if it can be expressed in the form or

step 1

Find the constant of proportionality k

For

substitute

the linear equation is equal to

using a graphing tool

see the attached figure

step 2

Find the unit rate

we know that

In a proportional relationship the constant of proportionality k is equal to the unit rate of change or slope m of the line, because the line passes through the origin

The units rate of change is 9

That means------> A change of 1 unit in t correspond to a change of 9 units in d

see the attached figure to better understand the problem

n a box of 12 tape measures, there is one that does not work. Employees take a tape measure as needed. The tape measures are not returned, once taken. You are the 8th employee to take a tape measure. Is this a binomial experiment?
a. Yes, the probability of success is one out of 12 with 8 selected.
b. No, the probability of getting the broken tape measure changes as there is no replacement.
c. Yes, you are finding the probability of exactly 5 not being broken.
d. No, binomial does not include systematic selection such as "eighth".

Answers

Answer:

b. No, the probability of getting the broken tape measure changes as there is no replacement.

Step-by-step explanation:

For each tape measure, there are only two possible outcomes. Either it is broken, or it is not, which means that the first condition for the binomial distribution is respected.

However, the tapes are not returned to the box, which means that in each trial, the probabilities of getting the tape with defect changes, which means that the binomial distribution cannot be used. So option b is the correct answer

Julio invest $15,000 in a savings account that pays 1.5% simple interest. How much will be in the

account after 5 years if Julio makes no withdrawals or deposits? *

Answers

Answer: Final amount

Step-by-step explanation:

Final amount = Simple interest + Principal

=Principal x Rate x Time + Principal

= Principal (Rate x Time +1) [Simple interest =Principal x Rate x Time]

Given: Principal = $15,000, Rate = 1.5% = 0.015 [To conver % into decimal we divide it by 100]

Time = 5 years

Final amount = $(15000(0.015 ×5+1))

=$ (15000×1.075)

=$ 16125

Hence, there will be $16,125 in the account after 5 years if Julio makes no withdrawals or deposit.

2. Robert has three jobs. He worked at Young's Grocery and earned $5,805. He was a waiter at the A & B Restaurant and earned $12,445. He also earned $56,002

working for CCD Communications. Each employer took out 6.2% for Social Security. How much did Robert pay in Social Security?

Answers

Answer:

Robert paid $4,603.6 in Social Security.

Step-by-step explanation:

Robert total earnings:

$5,805 at Young's Grocery.

$12,445 at A&B Restaurant.

$56,002 at CCD Communications.

So his total earnings are of:

5805 + 12445 + 56002 = $74,252

How much did Robert pay in Social Security?

6.2%, that is, 0.062 of $74,252. So

0.062*74252 = $4,603.6

Answer:

x=9; JL= 23

Step-by-step explanation:

To find x:

If JL and KM are equivalent, then JL = KM. Substitute the equations and you get 2x+5 = 7x-40.

Put the similar terms on the same side by subtracting 2x from both sides and adding 40 to both sides. You will get 45=5x.

Get x alone by dividing both sides by 5 and you will get 9=x.

To find JL:

Substitute the x in 2x+5 (JL length equation) with 9. Your new equation will be 2(9) + 5.

2•9 = 18.

18+5=23

A store sells comic books. Each comic book costs the same amount. During a sale, the store reduces the price of each comic book by 1.45. Miguel

spends $12.88 on 2 comic books at the sale price.

What was the price of I comic bbok before the sale? Enter the answer in the box.

Answers

Answer:

$7.89

Step-by-step explanation:

Given that Miguel spends $12.88 on 2 comic books then the amount spent on 1 book given that the prices of the books are equal will be

= $12.88/2

= $6.44

Given that the store reduced the price of each comic book by $1.45 then the price P of 1 comic book before the sale

P = $6.44 + $1.45

= $7.89

The cost of 1 comic book before the sale ( which is before the reduction in price) is $7.89
