If you would like to know how many pints should Jake measure, you can calculate this using the following step:
1 pint ... 2 cups
x pints = ? ... 8 cups
1 * 8 = 2 * x
8 = 2 * x /2
x = 8/2 = 4 pints
The correct result would be 4 pints.
Answer:
A
Step-by-step explanation:
x | y
0 0
1 4
2 n -> 8
3 12
I've rewritten the x-y table so it's easier to read.
Take a point: 2,8. 2 times 4 is 8.
Take another point: 3,12. 3 times 4 is 12.
Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.
(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
Answer: $1702
Step-by-step explanation: So in two years she gained 144 dollars in interest. In one year she gained 72. So, to get her interest in 7 years, multiply 72 by 7. You will get $502. Add 502 to 1200 and you get $1702.
Hope this helps
Answer:
so lets remember the formula for interest first.
#lightbulb
here it is A = P(1 + rt)
all we really have to do is plug in our rates, principles, and time into equation.
P = $800
t = 2 years
r = 6.5% or as a decimal 0.065
now lets look at our new equation that finally has numbers in it
A = 800[1 +(0.065)(2)] first lets take care of the 0.065 and 2 by multiplying them together. thus our new equation.
A = 800(1+ 0.13) then we add the 1 to the 0.13 and get 1.13
800(1.13) from here we just multiply and that equals 904
since we are looking for what is earned we take 904 and subtract 800 to get that answer. Here is the math.
904 - 800 = 104
he made 104 dollars in 2 years
hope this is right
Step-by-step explanation:
Answer:
a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100
Formula of test statistic =
=
=
refer the z table for p value
p value = 0.8849

refer the z table for p value
p value = .000148
p value of part B is less than Part A because part B have 10 times the number the tosses.
