Hey there!

To start, this is a compound interest problem, meaning you will have to use this formula:
A=P(1+\frac{r}{n})^nt

P represents the principal amount, r represents the rate as a decimal, n represents the amount of times compounded, and t represents the number of years compounded.

Now, plug in your known values:
P=300 (your initial amount)
r=0.02 (your rate of 2%)
n=1 (compounded annually, meaning once every year)
t=4 (the number of years you need to find)

A=300(1+0.02/1)^(1*4)

Now, simplify:
A=300(1+0.02)^4
=300(1.02)^4
=300(1.08243216)
=324.729648

Finally, round to the nearest cent and you get $324.73 as your final answer.

The weights (in pounds) of 18 preschool children are
ivanzaharov [21]

Answer:

22.8 and 37.5

Step-by-step explanation:

Given the

The weights (in pounds) of 18 preschool children are

32, 20, 25, 27, 31, 22, 30, 23, 44, 37, 33, 45, 41, 24, 34, 21, 39, 29

To find its 20th percentile and 75th percentile.

In ascending order we get like this

Position  X (Asc. Order)

1  20

2  21

3  22

4  23

5  24

6  25

7  27

8  29

9  30

10  31

11  32

12  33

13  34

14  37

15  39

16  41

17  44

18  45

Percentile position = (no of entries +1)20/100 = 19/5 = 3.8

Since posiiton is not integer we use interpolation method.

The value of 3.8 - 3 = 0.8 corresponds to the proportion of the distance between 22 and 23 where the percentile we are looking for is located at.

Hence 20th percentile = 22+0.8(23-22)=22.8

So answer is 22.8

----------------------

75th percentile

Percentile posiiton = 19(75)/100 = 14.25

75th percentile= 37+0.25(39-37)=37.5

Which equation represents a line that passes through (5, 1) and has a slope of 1/2?
lesya692 [45]

Answer:

C

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = \frac{1}{2} and (a, b) = (5, 1), so

y - 1 = \frac{1}{2}(x - 5)
