The graph shows the level of ibuprofen, y units, in a patient’s bloodstream x hours after the ibuprofen was taken. Select the correct answer to complete the blanks in the sentence: "The level of ibuprofen in the patient's bloodstream increased from _____ hours to _____ hours."
The graph is missing, so i have attached it.
Answer:
From 0 hours to 2 hours.
Step-by-step explanation:
From the attached graph, we can see that on the y-axis, denotes the level of ibuprofen in the patient’s bloodstream while the x-axis denotes the amount of hours after the ibuprofen was taken.
Now, looking at the graph, we can see that the curve goes up from a time of 0 hours which corresponds to 0 mg of ibuprofen to a time of 2 hours which corresponds to 400 mg of ibuprofen.
After that point, the curve begins to to go down. Since we are concerned with increase, we will make do with the first statement.
Thus, we can say the period at which the level of ibuprofen increased was from 0 hours to 2 hours.

Indicate a general rule for the nh term of this sequence.
12a, 15a, 18a, 21a, 24a,...
Answer:
The general rule for the nth term of this sequence will be:
[tex]a_n=3na+9a[/tex]
Step-by-step explanation:
Given the sequence
12a, 15a, 18a, 21a, 24a,...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Here,
a₁ = 12a
computing the differences of all the adjacent terms
d = 15a-12a = 3a, d = 18a-15a=3a, d=21a-18a=3a, d=24a-21a=3a
using the nth term formula
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting a₁ = 12a, d = 3a
[tex]a_n=12a+\left(n-1\right)3a[/tex]
[tex]=12a+3na-3a[/tex]
[tex]=3na+9a[/tex]
Therefore, the general rule for the nth term of this sequence will be:

Margaret is completing a lifeguard course and is completing the test at the end of the
course. There are 75 total questions that she needs to complete and she is 36% complete.
How many more cuestions does she need to complete
Q
Answer:
Step-by-step explanation:
For your first question,
Total percentage of people cheering for visiting team = 45%
Total percentage of people cheering for home team = 55%
Total number of people cheering = 1200
Therefore, the number of people cheering for visiting team = 45% of 1200
= [tex]\frac{45}{100}[/tex] × 1200
= 45 × 12
= 540 people
For your second question,
Total number of questions = 75
Total percentage of the number of questions he completed = 36%
Percentage of the amount of questions left = 100 - 36 = 64%
Therefore, the number of questions left to complete = 64% of 75
= [tex]\frac{64}{100}[/tex] × 75
= [tex]\frac{64}{20}[/tex] × 15
= [tex]\frac{64}{4}[/tex] × 3
= 16 × 3
= 48 questions are left

Of 15 possible books, you plan to take 7 with you on vacation. How many different collections of 7 books can you take?
The number of collections of 7 books can you take is 1685.
What is Algebra?
Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
Total books= 15
n = 15 (the number of possible books) and r = 7 (the number of books to be taken).
Now,
To find the number of different collections of 7 books, we can use the formula for combinations. Combinations are ways of selecting items from a collection, such that the order of selection does not matter.
The formula for combinations is:
nCr = n! / (r! (n - r)!)
where n is the number of items in the collection, r is the number of items to be selected, and ! is the factorial operator.
We can plug these values into the formula:
15C7 = 15! / (7! (15 - 7)!)
= 15! / (7! 8!)
= (15 x 14 x 13 x 12 x 11 x 10 x 9 x 8!) / (7! 8!)
= (15 x 14 x 13 x 12 x 11 x 10 x 9) / (7 x 6 x 5 x 4 x 3 x 2 x 1)
= (6435 x 1320) / (5040)
= 8491770 / 5040
= 1685.25
Since we cannot have a fraction of a collection, we round down to get the final answer:
15C7 = 1685
Therefor, by algebra the answer will be 1685.

A student took two national aptitude tests. The national mean and standard deviation were 325 and 100, respectively, for the first test, and 50 and 6, respectively, for the second test. The student scored 425 on the first test and 65 on the second test. Use z-scores to determine on which exam the student performed better relative to the other test takers. first exam
Answer:
Second test
Step-by-step explanation:
Given that :
FIRST TEST
Mean (m) = 325
Standard deviation (s) = 100
Score (x) = 425
SECOND TEST
Mean (m) = 50
Standard deviation (s) = 6
Score (x) = 65
Express both scores as standardized scores:
Zscore = (x - m) / s
First Score :
Zscore = (425 - 325) / 100
Zscore = 100/100 = 1
SECOND SCORE :
Zscore = (65 - 50) / 6
Zscore = 15 / 6 = 2.5
Student performed better on second test :
Zscore second > Zscore first

A tablet that regularly sells for $330 was on sale for 15% off. If Jeremiah paid $302.94 total including tax, what is the sales tax
Answer:
8% sales tax
Step-by-step explanation:
$330 x .15 = $49.50
$330 - $49.50 = $280.50
$302.94 - $280.50 = $22.44
$22.44/$280.50 = .08 x 100 x 8%
Write an equation that represents the tile pattern in the table below
Answer:
y=3x+2
Step-by-step explanation:
First find the slope or m in the line of equation y=mx+b
to find slope you need two points, plug in to y2-y1 / x2-x1
so lets use points (0,2) (1,5)
5-2 / 1-0 = 3
m=3
we have y=3x + b
now we find b by pugging in a point, let's use (0,2)
2 = 3(0) + b
b= 2
y=3x+2
