There are 80 cupcakes to be sold at school for a
fundraiser.
1/4 were chocolate
1/5 were vanilla
The rest were strawberry flavored. How many
cupcakes were strawberry flavored?
Answer:
44
Step-by-step explanation:
Let S = strawberry count
Chocolate = 1/4 * 80 = 20
Vanilla = 1/5 * 80 = 16
Total = C + V + S
80 = 20 + 16 + S
80 - 20 - 16 = S = 44

Elliot invests 15000 in an investment certificate that pays 2% compounded annually. How much interest will he have earned in 2 years?
$15300
Second year:$15606
Step-by-step explanation:First year:300 is 2% of 15000, so we add that. The result we have is $15300.
Second year:306 is 2% of 15300, so we add that to the original value. The result is $15606.
Side note:
All you need to know is the Interest Rate Formula: [tex]p(1+r/100)^n[/tex]. By the way, that's the simple compound interest rate formula. The simple interest rate formula is [tex]p+(r/100)^n[/tex].

The inverse of the function g(x)=x−65 can be written in the form g−1(x)=ax+b. What is the value of a?
9514 1404 393
Answer:
a = 1
Step-by-step explanation:
The slope of the inverse of a linear function is the inverse of the slope of the original function.
The slope of g(x) is the coefficient of x: 1.
The inverse of 1 is 1/1 = 1.
The slope of the function g^-1(x) is 1, so a=1.
_____
Additional comment
g^-1(x) = x +65 . . . . . a=1; b=65

Reanna is making a scrapbook which holds 14 photos on each 2-page spread.
Tables are used to show the relationship between variables in a visual form. The equation of the situation is: [tex]y = 7x[/tex]
The complete table is as follows:
[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]
Given that:
[tex]2\ page = 14\ photos[/tex]
Let:
[tex]y \to pages[/tex]
[tex]x \to photos[/tex]
So, we have:
[tex]2y = 14x[/tex]
Divide by 2
[tex]y = 7x[/tex]
To fill the table, we simply multiply both sides by the same constant.
Multiply by 0.5
[tex]2\ page \times 0.5= 14\ photos \times 0.5[/tex]
[tex]1\ page = 7\ photos[/tex]
Multiply by 2
[tex]2\ page \times 2 = 14\ photos \times 2[/tex]
[tex]4\ page = 28\ photos[/tex]
Multiply by 3
[tex]2\ page \times 3 = 14\ photos \times 3[/tex]
[tex]6\ page = 42\ photos[/tex]
So, the table is as follows:
[tex]\left[\begin{array}{cccccc}{Pages}&1&2&4&6&8\\{Photos}&7&14&28&42&56\end{array}\right][/tex]

Demichael orders a set of numbers on his
homework. In descending order, the first
number is 5 1/2 and the last number is 5 1/3
Which of the following numbers is NOT in
Demichael's list?
A V25
B 5.45
C 5 12 름
D 5.34
The numbers are ordered, such that the first number (the largest one) is:
(5 + 1/2)
And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.
We want to see which of the following numbers is not on the list:
A) √25
B) 5.45
C) 5 12
D) 5.34
One of these numbers can only be in the list if it is larger than (5 + 1/3) and smaller than (5 + 1/2).
To see this easier, let´s rewrite both of these:
5 + 1/2 = 5 + 0.5 = 5.5
5 + 1/3 = 5 + 0.33 = 5.33
Then if a number is smaller than 5.33, the number can't be in the list.
Here we can see two numbers that are smaller than 5.33
These are:
Option A) √25 = 5 < 5.33
Option C) 5.12 < 5.33
And there is no number larger than 5.5
Concluding, the numbers that are not in Demichael's list are:
√25 and 5.12

Step-by-step explanation:
√89 is irrational number because it is not a perfect squareLet's suppose we conduct a hypothesis test about the mean value of something, and determine that we should reject the null hypothesis. What does that mean?
a. Our hypothesized mean has been proven incorrect
b. The difference between our sample mean and our hypothesized mean was most likely due to random chance.
c. The difference between our sample mean and our hypothesized mean was statistically significant.
d. The difference between our sample mean and our hypothesized mean was not statistically significant.
Answer: Choice C.
The difference between our sample mean and our hypothesized mean was statistically significant.
=========================================================
Explanation:
The null hypothesis is always set up in a way to state the following: "The mean mu is equal to some value"
The mu is a greek letter often used as the population mean symbol. The actual symbol itself looks like this [tex]\mu[/tex]
When we reject the null, we reject the idea that the mu is whatever stated value we said in the null. So we must go with the alternative hypothesis.
The sample mean we computed (xbar) is different enough from the mu value that we're able to make such a rejection. We consider this statistically significant, which is another way of saying that such a difference is not simply due to random chance.

Miss Marple’sgrandfather passed away and she attended the reading of the will. The estate was valued at $8,424,000. It was decided that 23of the estate would be given to his children. Of the remainder, 15would be used to create a scholarship for mathematics majors at a local university and the rest would be divided evenly among his fourgrandchildren, of which Miss Marplewas one. a.How much money was used for the scholarship?[3 pts]b.What fractionof the estate did Miss Marpleend up inheriting?
The amount of money used for scholarship and the fraction of the estate gotten by Miss Maple are :
Scholarship amount = $561,600Fraction gotten by Miss Maple = 1/30The entire fraction of the estate = 1/1
Fraction given to children = 2/3
Fraction left = Total - fraction given to children
Fraction left = 1/1 - 2/3 = 1/3
For scholarship :
1/5 of fraction left :
1/5 of 1/3 = 1/5 × 1/3 = 1 /15
Fraction Given to grand children :
1/5 - 1/15 = 2/15
Amount of money used for scholarship :
1/15 × 8424000 = $561,600
B.)
Since There are four grand children and it was equally shared among them:
Miss Maple is one of the grand children:
Fraction each grandchild gets is :
2/15 ÷ 4
2/15 ÷ 4/1
2/15 × 1/4 = 2/60 = 1/30
Hence, miss Maple will get 1/30

The nth term of a sequence is 5n + 1.
Which of these statements is true?
None of the terms are multiples of 5.
All of the terms are multiples of 5.
Oo
Some of the terms are multiples of 5.
Answer:
2nd option
Step-by-step explanation:
note that
5n ← generates multiples of 5, that is
5 × 1 = 5
5 × 2 = 10
5 × 3 = 15
5 × 4 = 20 , etc
5, 10, 15, 20, ....... are multiples of 5
but 5n + 1 does not generate multiples of 5 as
5 + 1 = 6
10 + 1 = 11
15 + 1 = 16
20 + 1 = 21
6, 11, 16, 21 are not multiples of 5
