In the data that are given above, it can be seen that the first point is $1.1 million, the second is $1.4 million which is 0.3 million greater than the first. Also, the third is $1.7 million which is $0.3 million greater than the third. The equation that best represents the given scenario is,
                                          0.8 + 0.3(n)
The answer is the first choice.

Please help,<br> Find the perimeter of the figure to the nearest hundredth
ElenaW [278]

Answer:

36.56 in

Step-by-step explanation:

perimeter is the sum of all sides

u add all the sides of the square by 6

6+ 6 + 6 + 6 = 24

circumference is the line around the circle

circumference = 3.14 x diameter

c = 3.14 x 4

c = 12.56

24 + 12.56 = 36.56

to the NEAREST HUNDREDTH????? ok welll thats alr

remember

5 or more, raise the score

4 or less, let it rest

this should be fine since the last 6 is alr in the hundredth place :)

e = k.m
360 = k.60
k = 360/60 = 36/6 = 6
108 = 6.m
108/6 = m = 18

It is estimated that approximately 10.5% of Americans are afflicted with diabetes. Suppose that a new diagnostic test is being c
Alla [95]

Answer:

0.03

Step-by-step explanation:

Percentage of americans with diabetes = 10.5% = 0.105

Percentage of americans without diabetes = 89.5% = 0.895

Adults over 40 with diabetes tested positive = 95% = 0.95

Adults over 40 with diabetes tested negative = 5% = 0.05

Adults over 40 without diabetes tested positive = 3.5% = 0.035

Adults over 40 without diabetes tested negative = 96.5% = 0.965

The probability of selecting an adult over 40 without diabetes but positive diagnosis;

     = 0.895 * 0.035

     = 0.031325

     = 0.03
