The graph depicts the growth in costs using a line segment. Use the midpoint formula to approximate the cost during the year 1987.The approximate cost during the year 1987 was $ ____.
Answer:
The approximate cost during the years 1987 was $7527
Explanation:
The midpoint formula is:
[tex]M(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]For two given points.
In this case, we can see in the graph the points (1983, 5021) and (1991, 10033)
Then, using the midpoint formula:
[tex]M(\frac{1983+1991}{2},\frac{5021+10033}{2})=M(1987,7527)[/tex]Thus, the approximation for the year 1987 is $7527

Stefan is baking taquitos for a school fundraiser. The recipe calls for 2 1/2 cups of beans and 3 1/4 cups of rice. What is the ratio between cups of beans and cups of rice?
The ratio between cups of beans and cups of rice is 10/13 . Option C
What is ratio?
A ratio can described as an ordered pair of numbers, like y and z, that is written mathematically in the form y / z where the denominator of the fraction is not equal to zero.
It is known to describe the number of times an element or number contains another number proportionally.
It is also seen as the comparison of two quantities, elements or numbers that has the same units and likewise, explains how much one of the elements or quantity is found in the another one.
This is done based on their sizes or magnitudes.
A proportion is a mathematical equation with two ratios set equivalent or equal to each other.
Given that;
Beans = 2 1/ 2 cups
Rice = 3 1/4 cups
Convert to mixed fractions;
Beans = 5/2
Rice = 13/4
Now, divide the cups of beans by that of rice;
= 5/ 2 ÷ 13/4
= 5/2 × 4/13
= 10/13
Hence, the ratio is 10/13

Tobin's friend Rose claims that she can read minds. To test
Rose's abilities, Tobin draws 3 cards without replacement
from a standard deck of 52 playing cards. Tobin asks Rose
to identify each of the 3 cards she drew in order.
Assume that Rose has no special abilities and is randomly
guessing the cards.
What is the probability that Rose identifies all 3 cards in
the correct order?
The probability that rose identifies all 3 cards in the correct order is 1/132,600 by the concept of permutation.
What is permutation?It is the separate arrangements of a given number of associates taken all at once, or some of them, or just a few of them. There are two possible meanings, AB and BA, for instance, if we have the two elements A and B.
Following the arrangement of 'r' items from a total of 'n' elements, the number of permutations is,
nPr = n! / (n – r)!
Here to obtain the probability in correct order use permutation formula
Recall that, Probability is calculated as favorable outcomes divided by all possible outcomes.
Favorable number of outcomes = 1 (as only one order is correct)
Total outcomes = 52p3 (since 3 cards to be arranged from pack of 52)
So, the probability of rose identifies all 3 cards in correct order =1/52p3
Probability = [tex]\frac{1}{52!/(52-3)!}[/tex]
Probability = 49! /52!
Probability = 49! /52*51*50*49!
Probability = 1/52*51*50
Probability = 1/132,600
Therefore, the probability that rose identifies all 3 cards in the correct order is 1/132,600.

3² +4² + 12² is equal to n² for some positive number n . Find n.
Answer:
n = 13
Step-by-step explanation:
For this, you need to square all of the numbers and then add them together. Most of the time, you can put them into a calculator but I will work it out below.
Squaring means multiplying a number by itself, so we get:
3² + 4² +12² =n²
Turns into:
(3*3) + (4*4) +(12*12) = n²
Then work out the multiplication:
9 + 16 + 144 = n²
Add everything together
169 = n²
Now take the square root of each side:
[tex]\sqrt{169} =\sqrt{n^{2}}[/tex]
This comes out to be:
± 13 = n
The question asks for the positive number, so you answer is:
n = 13

Part 3: Solve a real-world problem using a cube root function.
Once Isabel rented the warehouse space, she decided to post ads on several social media sites to advertise her online bookstore. Let x represent the number of months the ads have been posted. Isabel finds that the function below describes the number of books sold as a function of the number of months her ads have been posted.
f(x) = 1000 + 1000
⦁ How many books were sold after 8 months? (3 points)
⦁ Graph the function. (10 points)
Considering the given function, it is found that 3000 books were sold after eight months.
FunctionThe function in this problem is defined as follows:
f(x) = 1000(∛x) + 1000
In which f(x) represents the number of books sold after x months.
After eight months, we have that x = 8, hence the number of books is calculated as follows:
f(8) = 1000(∛8) + 1000
The lone instance of x in the function was replaced by eight to find the numeric value.
The cube root of eight is calculated as follows:
8 = 2 x 2 x 2 = 2³
Hence:
∛8 = 2
Thus the numeric value of the expression is:
f(8) = 1000(∛8) + 1000 = 1000 x 2 + 1000 = 2000 + 1000 = 3000 books.
The graph of the situation is given by the image at the end of the answer, at a domain of x >= 0, as the number of months cannot assume negative values.

Which of the following is an example of the associative property of multiplication?7 . (3 . 5) = (7 . 3) . 507. (3+5) = 21 + 357.(3.5) = 7 . (5. 3)0.1=1
The associative property of multiplication states that you can choose any pair of numbers to multiply first when there are more than two numbers being multiplied. This doesn't change the final result:
a . b . c = (a . b) . c = a . (b . c)
So, we see an example of such property in the first option:
7 . (3 . 5) = (7 . 3) . 5
Let's check this is indeed true:
7 . (3 . 5) = 7 . 15 = 105
(7 . 3) . 5 = 21 * 5 = 105
Therefore, the first option is correct.
Notice that the second option uses the distributive property of multiplication over addition:
a . (b + c) = a . b + a . c
The third uses the commutative property of multiplication:
a . b = b . a
The fourth is wrong since zero multiplied by any number is zero, not one:
0 . a = 0, for all values of a.
