Answer:
[tex](\frac{1}{2}) ^{3} - (\frac{1}{4} )^{2} +\frac{1}{2} = \frac{9}{16}[/tex]
Step-by-step explanation:
Explanation:-
Given
[tex](\frac{1}{2}) ^{3} - (\frac{1}{4} )^{2} +\frac{1}{2}[/tex]
= [tex]\frac{1}{8} - \frac{1}{16} + \frac{1}{2}[/tex]
[tex]=\frac{2-1}{16} + \frac{1}{2}[/tex]
= [tex]\frac{1}{16} + \frac{1}{2}[/tex]
= [tex]\frac{1+8}{16}[/tex]
= [tex]\frac{9}{16}[/tex]
A migrating bird flies 800 miles in 16 hours. How many miles does it fly in 7 hours?
Hi there!
miles=350 miles
1.Divide starting terms:
[tex]800*16=50[/tex]
2.Multiply by 7:
[tex]50[/tex]·[tex]7=350[/tex]
Therefore, a migrating bird flys 350 miles per 7 hours.

Brian has 8 feet of canvas. He needs 1/4 foot to make a painting.
How many paintings can Brian make?
Answer:
32 paintings
Step-by-step explanation:
You have to divide 8 by [tex]\frac{1}{4}[/tex]
turn 8 into a fraction by putting a 1 under it, [tex]\frac{8}{1}[/tex], and flip the other fraction, [tex]\frac{4}{1}[/tex]
now, you multiply the fractions
[tex]\frac{8}{1}[/tex] ×[tex]\frac{4}{1}[/tex]= [tex]\frac{32}{1}[/tex], so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.
The solution is, Brian can make 32 paintings
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
You have to divide 8 by
turn 8 into a fraction by putting a 1 under it, 8/1 , 4/1 and flip the other fraction,
now, you multiply the fractions
8/1×4/1=32 ,
so you get 32 over one, which you can just simplify into 32
Brian can make 32 paintings.

Answer:
3 3/20
Step-by-step explanation:
so you make the denominator the same for the two numbers shown. I did 20. So 3/5 turns into 12/20 and 1/4 turns into 5/20 (you can do 12 if you like for the denominator also) So now, the equation is 3 12/20 minus 5/20, which i got 3 3/20.

Jamal has $15.00 to spend at the concession stand. He buys nachos for $7.50, and he wants to purchase some sour straws for $1.50 each. How many sour straws can Jamal purchase with the money that he has?(solve with inequality/solve for x)
Answer:
x = 5
$15.00 is the total amount of money Jamal has right? To find the remaining amount of money Jamal has subtract 15 - 7.5 (price of nachos) = 7.5 (remaining amount of money Jamal has.) Now for part 2, since the sour straws are $1.50 each you just have to multiply X to get close as close to the remaining amount of money as possible.
1.50× 5 (amount of sour straws) is equal to 7.50 (price of 5 sour straws).
To check your answer let's add the price of nachos (7.50) and 5 sour straws (7.50) which is 15.00 the total amount Jamal brought with him.

Hey there!
a.) 1 inch
beginning = 2; end = 3; difference of 1
b.) December, because the length was, let's say, 2, then it went down 1 (so we're at 1), then went up 3 (4), then went down
c.) in December
Hope it helps, have a great day!
Step-by-step explanation:
a.total change in my hair =2-1+3-4+3=3inches
b.my hair is longer on December because the length of my hair is 3inches but 2inches in January.
c.my hair is longest as on December because the length of my hair is longer than on other month.

Which voting methods satisfy the Majority Fairness Criterion?
Find the value of. X in the proportion 5/9=x/36
Answer:
x=20 hope this helps :)
The value of X is 20.
To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.
Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.
5/9 * 4/4 = 20/36.
Thus meaning X = 20. I hope this helps!

Suppose that an Internal Revenue Service (IRS) representative claims that the average tax deduction for medical care is $1,250, and assume that this variable is normally distributed. A taxpayer who believes that the deduction might be less than $1,250 decides to randomly sample 12 families who have an average deduction of $934 with a standard deviation of $616. a. What are the null and alternative hypotheses? b. What is the value of the test statistic, i.e. t-stat, in this example? Show your work. c. What is the p-value associated with this test statistic? (HINT: you have less than 30 observations so you will need to use t-table to obtain critical values.) d. What can you conclude at the 10-percent level of significance? What can you conclude at the 5-percent level of significance? Explain. (HINT: you have less than 30 observations so you will need to use t-table to obtain critical values.)
Step-by-step explanation:
We have bar x = 934
S = 616
n = 12
A.
Null hypothesis: h0: u = 1250
Alternative hypothesis: h1: u< 1250
B. To get the t test statistic
T = 934-1250/616/√12
T = -316/616/3.4641
= -316/117.824
= -1.777
C. O value = p(t<-1.777)
This gives 0.0516
D. At 10% significance
O.0516<0.1 so we reject the null hypothesis and conclude that this deduction is < than 1250
At 5% level of significance
O.o516>0.05. we do not reject the null hypothesis. We conclude there is insufficient evidence of claim being less than 1250
