Answer:

Line C is the correct answer

Step-by-step explanation:

A: y = (-20/3) * x + 56

B: y = (-10/3) * x + (80/3)

C: y = 2 * x + 8

D: y = (27/7) * x - 7

check: line C --  y = 2 * (-7) + 8 = -6        (-7, -6)

                           y2 = 2 * 6 + 8 = 20        (6, 20)

                           y3 = 2 * 2 + 8 = 12          (2, 12)   .... correct

Jeremy invested $60,000 earning 6.5% simple interest. How much interest will he earn over 5 years?
const2013 [10]

Answer:

$19500

Step-by-step explanation:

Interest = PRT/100

Where

P = principal

R = rate

T = time

Given

P = $60000

R = 6.5%

T = 5 yrs

Interest = 60000 x 6.5 x 5 /100

Multiply through

1950000/100

19500

$19500

He will earn $19500 interest over 5 years

One number is 10 times as large as another, and their difference is 81. Find the numbers.
yulyashka [42]
The smaller number=x
the larger number=10x
we can suggest this equation:
10x-x=81
9x=81
x=81/9=9

The smaller number is 9
The larger number is :  10x=10(9)=90


Answer: the larger number is 90.

Can someone please help me with this?
storchak [24]

Answer:

y = x

Step-by-step explanation:

i took two points which are very close to the trend line - (3,3) and (5,5) - to get the slope

the slope is 2/2 or 1 and the y-intercept is zero

this means the trend line is 'y = x'

1. Consider the hospital emergency room data in Example 2-8. Let A denote the event that a visit is to hospital 4, and let B den
mario62 [17]

Answer:

A = 0.2264

B =0.9681

C = 0.9891

Step-by-step explanation:

The concept of conditional probability is applied here, probability been the likelihood of an event occurring. two events A and B are said to be mutually exclusive is one event precludes the happening of the other event i.e one is dependent on the other one occurring.

Conditional probability on the other hand is the happening of an event taking into consideration that an event had already happened.

Let P(A) and P(B) be the probability of event and B occurring.

P(A and B) is the probability of both A and B = P(A) x P(B)

P(A or B) = is the probability of either A or b = P(A union B)

as such, P(A union B) = P(A) + P(B) - P(A and B).

The steps and appropriate explanation is as shown in the attached file.
