recorded in inches (brother's height minus sister's height), was calculated for each pair. The 95% confidence interval
for the mean difference in heights for all brother-and-sister pairs in this population was (-0.76, 4.34). What was the

Suppose that when your friend was born, your friends parents deposited $2000 in an account paying 5.9% interest. What will the account balance be after 15 years?
Answer:
FV= $4,725.74
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $2,000
Number of periods (n)= 15 years
Interest rate (i)= 5.9% = 0.059
To calculate the Future Value, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 2,000*(1.059^15)
FV= $4,725.74
What the volume of a cylinder with a diameter of 6mm and a height of 7 mm.it says it’s 700 something but the only answers on the test are as low as 100 and highest is 230? Help plz
8th grade math*
Answer: 197.82mm³
Step-by-step explanation:
Volume of a cylinder = πr²h
where,
π = 3.14
r = Diameter/2 = 6mm/2 = 3mm
h = 7mm
Volume = πr²h
= 3.14 × 3² × 7
= 3.14 × 9 × 7
= 197.82mm³
The volume of the cylinder is 197.82mm³
There is a population of 10,000 bacteria in a colony. If the number of bacteria doubles every 14 hours, what will the population be 28 hours from now?
Answer:
for the first 14 hours it doubles to 20,000, then once it reaches 28 hours it'll be 40,000. its an exponential growth
The population growth of bacteria after 28 hours will be equal to 40,000.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers. Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the set of information in the question,
Total population of Bacteria = 10,000
Rate of growth of bacteria = Twice in 14 hours
Rate of growth in 28 hours = 4 times the total population.
Then the total bacteria (B) in the colony after 28 hours,
B = 4 × 10,000
B = 40,000

Use algebra to show that the recurring decimal 0.2813 =
557
198
Step-by-step explanation:
tell me the answer when u get too!!
btw its 557/1980
The proof is shown in the solution.
What are recurring decimals?A repeating decimal or recurring decimal is a decimal representation of a number whose digits are periodic, and the infinitely repeated portion is not zero.
Given that, show that the recurring decimal 0.2813 = 557 / 198
Let 0.2813 be x
0.2813 = x......(i)
2813.2813 = 10000x......(ii)
Subtracting eq(i) from eq(ii)
2813 = 999x
x = 2813 / 999
x = 557 / 198
Hence, proved

Answer:
13 quarts
Step-by-step explanation:
Remember this:
1 mug = 16 oz
1 quart = 32 oz
Find total quarts of coffee.
Setup proportion and solve for x ounces:
[tex]\frac{1 mug}{16 oz} =\frac{26 mugs}{xoz}\\\\x oz=16(26)=416 oz[/tex]
Setup another proportion to solve for x quarts and also use the 416 oz.
[tex]\frac{32oz}{1 qt} =\frac{416oz}{xqt} \\x=\frac{416}{32} = 13 qt[/tex]

Kallisto built a rectangular sign that measured 2 and 3/4. The width is 1 and 1/4 shorter than the length. To find the area, multiply the length and width. What is the area in square feet write an equation to solve it
Answer:
l = 1 5/16
w = 1/16
A = 21/16 x 1/16 = 21/256
Step-by-step explanation:
Perimeter = 11/4
l = length
w = l - 5/4
2l + 2(l - 5/4) = 11/4
2l + 2l - -5/2 = 1/4
multiply each side by 4
8l + 8l - 10 = 11
16l = 21
l = 21/16 or 1 5/16
width = 21/16 - 20/16 = 1/16

A satellite is 24,400 miles from the horizon of Earth. Earth’s radius is about 4,000 miles. Find the approximate distance the satellite is from the point directly below it on Earth’s surface. The diagram is not to scale.
Answer: There are several information's already given in the question. It will be easier to get the answer, if we write all the details down first.
AB = 13200 miles
AO = 4000 miles
OB = 4000 miles
Let us assume CB = x
Then
(x + 4000)^2 = (13200)^2 + (4000)^2
x = sqrt(13200^2 + 4000^2) - 4000
= 13793 - 4000
= 9793 miles.
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option.

Sally found 33 fossils. She found twice as many plant fossils as animal fossils. How many of each type of fossil did she find
Answer:
a = 11
b = 33
Step-by-step explanation:
Given :
Total fossil found = 33
Let :
Number of plant fossil = b
Number of animal fossil = a
a + b = 33
Plant fossil = 2 times number of animal fossil
b = 2a
Put b = 2a
a + 2a = 33
3a = 33
Divide both sides by 3
3a/ 3 = 33/3
a = 11
a + b = 33
11 + b = 33
b = 33 - 11
b = 22
Pete bought a house in 2009 for $200,000.
The value of his house increased by 10%
annually.
Answer:
Value of house in 2021 = $627,680 (Approx.)
Step-by-step explanation:
Given:
Value of house in 2009 = $200,000
Rate increased per year = 10% annually
Find;
Value of house in 2021
Computation:
Number of year = 2021-2009 = 12 year
Value of house in 2021 = Value of house in 2009[1+Rate increased per year]ⁿ
Value of house in 2021 = 200,000[1+10%]¹²
Value of house in 2021 = 200,000[1+0.1]¹²
Value of house in 2021 = 200,000[1.1]¹²
Value of house in 2021 = 200,000[3.1384]
Value of house in 2021 = $627,680 (Approx.)
