Answer:
There will be no difference in pain ratings from people protected by her spell and people who aren't protected by her spell.
Step-by-step explanation:
The claim in this scenario is the alternative hypothesis, which is what we wish to test ; the alternative hypothesis is thus ; people who are protected by spell will rate their pain as a result of cruciatus curse as less severe than the average person who does not use her protection spell ;
As we know, the null hypothesis is the opposite of the alternative hypothesis and the initial truth, which is ;
The average pain felt by both the user of the pain protections spell and those who do not feel the same amount of pain.

The number of cans the soup kitchen has is represented by the equation, y = -63x + 825, where x represents the number of days and y represents the number of cans. How many cans will the soup kitchen have after 10 days?
Answer:
this equation means that if your multiple the amount of days by -63 and add 825 you'll get the amount of cans
can substitute 10 in as x so
-63(10)+825
-630+825
195
so the soup kitchen will have 195 cans after 10 days
2,10,18,26 find the 61st term
Answer:
482
Step-by-step explanation:
We can see that the numbers shown resemble an arithmetic sequence because they have a common difference. The formula for the nth term of an arithmetic sequence is:
[tex]a_{n} =a_{1} +(n-1)d[/tex]
Where [tex]a_{1}[/tex] is the first term, [tex]a_{n}[/tex] is the nth term, and [tex]d[/tex] is the common difference. To find the 61st term, all we need is the first term and the common difference. By looking at what given, we can say the first term is 2. Now, to find the common difference, we find the difference of a term from the term before it. In this case we can do [tex]10-2[/tex], which is [tex]8[/tex] , or the common difference. Since we have everything we need, it can be plugged into the equation:
[tex]a_{61} =2 + (61 - 1)*8\\a_{61} = 2 + 60*8\\a_{61} = 2 + 480\\a_{61} = 482[/tex]
So, the 61st term is 482.

Answer:
She is not correct
Step-by-step explanation:
distance = rate x speed
Damon:
120 = 2r
r = 60 miles per hour
Ashley:
135 = 2.3r
r = 58.7 miles per hour

NO LINKS NO FILES! Jill says that the rules for multiplying and dividing integers are alike. Do you agree? Explain.
Answer:
Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).
Answer:
I do not agree
Step-by-step explanation:
because in multiply negatives, the 2 negatives turn into a positive or multiplying positive and negative (and vice versa) becomes a negative still so the rules of multiplying and dividing are not alike integers. (For dividing it is the same!)
Liam bought pizza and wings for $27.58. How much change should Liam receive if he gave the clerk three $10 bills?
Use coins and bills to help solve.
A. $1.52
B. $2.42
C. $2.52
D. $12.42
Answer:
B. $2.42
Step-by-step explanation:
If Liam gave the clerk three $10 bills, that means he gave the clerk $30. This is because 3 times 10 equals 30.
Find how much change he will receive by subtracting $27.58 from the $30 that Liam gave to the clerk:
30 - 27.58
= 2.42
So, Liam will receive $2.42 in change.
The correct answer is B. $2.42
Answer:
2.42
Step-by-step explanation:
3 ten dollar bills = 3*10 = 30 dollars
Subtract the cost of pizza and wings
30 - 27.58
Line up the decimals
30.00
- 27.58
----------------
2.42
Which describes the shape of the distribution of total points in Mr. Price's science class? Please help
Answer:
The distribution is negatively (left) skewed
Step-by-step explanation:
Notice how most of the data is clustered on the right side of the distribution and there's more spread in the left side of the data, meaning the left tail is longer. This creates a negative skew in the data. Review the attached diagram to learn more.

An individual has $40,000 to invest: $28,000 will be put into a low-risk mutual fund averaging 6.9% interest compounded monthly, and the remainder will be invested in a high-yield bound fund averaging 9.8% interest compounded continuously.
Required:
a. Write an equation for the total amount in the two investments.
b. Write the rate-of-change equation for the combined amount.
c. How rapidly is the combined amount of the investments growing after 6 months? after 15 months?
Answer:
a) F(x) = 28,000( 1.00575 )^12x + 12,000e^0.098x
b) F'(x ) = 28,000 ( In 1.071224 ) ( 1.071224 )^x + 1176 e^0.098x dollar per year
c) 3228.94 dollar/year, 3428.73 dollar/year
Step-by-step explanation:
Capital = $40,000
$28,000 = low-risk mutual fund
6.9% monthly compounded interest for the low risk mutual fund
$12,000 = high-risk yield bound fund
9.8% continuously compounded interest
A) Equation for total amount in two investments
F(x) = F1(x) + F2(x) ----- ( 1 )
where :
F1(x) ( future value for monthly compounded interest)
= 28,000( 1 + 0.069/12 )^12x = 28,000 ( 1.00575 )^12x
F2(x) ( future value for continuously compounded interest )
= ( 40,000 - 28,000 )e^0.098x = 12,000 e^0.098x
back to equation 1
F(x) = 28,000( 1.00575 )^12x + 12,000e^0.098x
B Rate of change equation
f'(x) = d/dx (28,000( 1.00575 )^12x) + d/dx ( 12,000e^0.098x )
∴ f'(x) = 28,000 d/dx (1.00575^12)^x + 12,000 d/dx(b^x)
= 28,000 ( In 1.071224 ) ( 1.071224 )^x + 12,000 ( In b ) ( b^x )
f'(x ) = 28,000 ( In 1.071224 ) ( 1.071224 )^x + 1176 e^0.098x dollar per year
C) Determine how rapidly the combined amount will grow after 6 months and after 15 months
i.e. x = 0.5 , x = 1.25 years
after 6 months
28,000 ( In 1.071224 ) ( 1.071224 )^(0.5) + 1176*e^((0.098(0.50))
= 1993.88 + 1235.06 = 3228.94 dollar/year
after 15 months
28,000 ( In 1.071224 ) ( 1.071224 )^(1.25) + 1176*e^((0.098(1.25 ))
= 2099.47 + 1329.26 = 3428.73 dollar/year

If the exercise ball has been filled with Nitrogen which has a density of 0.2 grams per cubic inches. Find the mass in grams.
Options
11,581.2 grams
12,370.6 grams
13,891.5 grams
15,156.3 grams
Answer:
m = 11581.2 grams
Step-by-step explanation:
Given that,
The density of the ball, d = 0.2 g/in³
The radius of the ball, r = 24 inches
We need to find the mass of the ball in grams.
The density of an object is hiven by :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{m}{\dfrac{4}{3}\pi r^3}\\\\m=\dfrac{4}{3}\pi r^3\times d[/tex]
Put all the values,
[tex]m=\dfrac{4}{3}\pi \times 24^3\times 0.2\\\\m=11581.16\ g[/tex]
or
m = 11581.2 grams
Hence, the mass of the ball is 11581.2 grams.

2.02b + 4.30 = 2.00b + 6.30
Answer: b = 100
Step-by-step explanation:
simplifying
2.02b + 4.30 = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 2.00b + 6.30
reorder the terms:
4.30 + 2.02b = 6.30 + 2.00b
solving
4.30 + 2.02b = 6.30 + 2.00b
solving for variable 'b'.
move all terms containing b to the left, all other terms to the right.
add '-2.00b' to each side of the equation.
4.30 + 2.02b + -2.00b = 6.30 + 2.00b + -2.00b
combine like terms: 2.02b + -2.00b = 0.02b
4.30 + 0.02b = 6.30 + 2.00b + -2.00b
combine like terms: 2.00b + -2.00b = 0.00
4.30 + 0.02b = 6.30 + 0.00
4.30 + 0.02b = 6.30
add '-4.30' to each side of the equation.
4.30 + -4.30 + 0.02b = 6.30 + -4.30
combine like terms: 4.30 + -4.30 = 0.00
0.00 + 0.02b = 6.30 + -4.30
0.02b = 6.30 + -4.30
combine like terms: 6.30 + -4.30 = 2
0.02b = 2
divide each side by '0.02'.
getting: b = 100

Answer:
x = 6.93
y = 13.86
Step-by-step explanation:
We can solve x by;
Tan(60) = 12/x
Tan(60) * x = 12
x = 12 / Tan(60)
x = 6.93
We can solve y by;
A² + B² = C²
12² + 6.93² = y²
144 + 48.02 = y²
192.02 = y²
[tex]\sqrt{192.02}[/tex] = y²
13.86 = y
Hope this helps!
Can someone check if this is right please? If not what is the correct way?
A, B, and C are the coefficients. They are not the terms as you have written now.
A quadratic equation is in the form Ax^2 + Bx + C. Therefore, A = 1, B = 8, and C = -6.
The axis of symmetry is found using the equation -b/2a, as you've done. Therefore, the axis of symmetry is -8/2(1) = -4.
Hope this helps!! :)
Randy's gross salary is $760 per week. his salary is taxed at 16% what is his net salary
Answer:
$638.4
Step-by-step explanation:
Randy's gross salary (salary without any deduction) = $760
taxed rate =16%
Amount tax paid =tax% of gross income
=16/100 * $760
=$16*760/100
=$12160/100
=$121.6
net salary = gross salary - tax paid
=$760 - $ 121.6
=$638.4
Randy's net salary is $638.40
Randy's gross salary = $760 per week.
Tax paid on his salary = 16%
Net salary is the difference between the salary earned and the amount paid as tax. This will be:
= Salary - Tax
= $760 - (16% × $760)
= $760 - (0.16 × $760)
= $760 - $121.60
= $638.40
