On the first four exams, Steve's grades are 70, 76, 88, and 92. There is still one more exam and he is hoping to earn a B in the course. This will occur if the average of his first five exam grades is greater than or equal to 80 and less than 90. What range of grades on the fifth exam will result in earning a B?
The range of grades on the fifth exam that results in earning a B is ___? If the highest grade is 100, then
_____.
The range of grades on the fifth exam that will result in Steve earning a B in the course is 74 to 100 inclusive, as he needs at least a 74 to bring his average up to 80, and any score above 100 is not possible.
Explanation:To calculate the range of grades on the fifth exam that will ensure Steve earns a B in the course, we need to determine what final score on the fifth exam will result in an average between 80 and 90 for all five exams.
Let's first add up the scores from Steve's first four exams:
70 + 76 + 88 + 92 = 326To achieve an average of at least 80, the total sum of all five exam grades must be at least 400 (because 80 is the minimum average for a B, and 80 times 5 exams equals 400). So, the minimum score Steve needs on the fifth exam is:
400 - 326 = 74Steve needs at least a 74 on the fifth exam to achieve an average of 80. If we want to ensure the average does not reach 90, the total sum of all five exam grades must be less than 450 (because 90 times 5 exams equals 450). The highest score Steve can get on the fifth exam and still remain in the B range is:
450 - 326 = 124However, since Steve cannot score more than 100 on the fifth exam, the maximum score remains capped at 100.
Therefore, the range of grades on the fifth exam that will result in earning a B is 74 to 100 inclusive.

Hey there!
When we solve for x, we need to isolate x on one side.
This is just a one-step equation, meaning there is only one thing we need to do to solve for x, or isolate x.
Starting with 87 + x = 100:
Subtract 87 from each side.
87 - 87 + x = 100 - 87
Simplify. Subtracting 87 from 87 makes it equal to 0.
x = 13
Your answer is A. 13.
Hope this helps!

Answer:
[tex]50(5 - 3x)[/tex]
Step-by-step explanation:
The given expresion is
[tex]250 - 150x[/tex]
The greatest common factor is 50.
We rewrite using the distributive property to get;
[tex]50 \times 5- 50 \times 3x[/tex]We collect the highest common factor to obtain:
[tex]50(5 - 3x)[/tex]
Therefore when we factor out the greatest common factor from the given expresion we get;
[tex]50(5 - 3x)[/tex]
To apply the distributive property and factor out the greatest common factor from the expression 250-150x, we need to find the largest number that evenly divides into both numbers. In this case, the greatest common factor is 50, so the expression can be rewritten as 50(5 - 3x).
Explanation:To factor out the greatest common factor from the expression 250-150x, we need to find the largest number that evenly divides into both 250 and 150. In this case, the greatest common factor is 50. We can rewrite the expression as 50(5 - 3x).

the end of the year, after taxes, a manufacturing firm has $230,000 in revenues, $90,000 in production costs, and $140,000 in opportunity costs. How much economic profit did the firm make?
Answer: 50
Step-by-step explanation:
Final answer:
The firm's economic profit is calculated by subtracting both explicit and implicit costs from the total revenues. Upon performing this calculation, we determine that the firm made an economic profit of $0 since the costs equaled the revenues.
Explanation:
To calculate the economic profit of the firm, we subtract both explicit (actual monetary payments) and implicit (opportunity) costs from the total revenues. The firm has $230,000 in revenues after taxes, $90,000 in production costs (explicit costs), and $140,000 in opportunity costs (implicit costs). Therefore, the calculation for economic profit is as follows:
Total Revenues - Explicit Costs - Implicit Costs = Economic Profit
$230,000 - $90,000 - $140,000 = $0
So, the firm did not make any economic profit, as the explicit and implicit costs equaled the total revenues.

The correct answer is B.
A town has a population of 14000 and grows at 5% every year. What will be the population after 14 years, to the nearest whole number?
Using the exponential growth formula, the town's population of 14,000 growing at a rate of 5% per year will reach 27,706 after 14 years.
To calculate the future population of a town with a given growth rate, we use the formula for exponential growth, which is:
[tex]P_{t} = P_0 (1 + r)^t[/tex]
Given a town with an initial population (P0) of 14,000 and a growth rate (r) of 5% or 0.05, want to find the population after 14 years (t).
Plugging in the values into the formula:
P(14) = 14,000 × (1 + 0.05)¹⁴
P(14) = 14,000 (1.05)¹⁴
P(14) = 14,000 1.9791
P(14) = 27,706.24
To the nearest whole number, the population after 14 years will be 27,706.

A bag contains two red marbles and three blue marbles. You randomly pick a marble. Find the number of possible outcomes in the sample space.
Final answer:
The sample space for picking a single marble from a bag containing two red and three blue marbles has 5 outcomes, represented as R1, R2, B1, B2, B3.
Explanation:
To determine the number of possible outcomes in the sample space when you randomly pick a marble from a bag containing two red marbles and three blue marbles, you must consider each marble as a distinct possibility. Since there are 5 marbles in total, each draw from the bag has 5 potential outcomes. It does not matter the color of the marble; each draw represents a distinct event with 5 possible outcomes.
Therefore, the sample space, which represents all possible outcomes, contains 5 elements. These outcomes can be represented as R1, R2, B1, B2, and B3, where 'R' stands for red marbles, 'B' stands for blue marbles, and the numbers differentiate between the individual marbles.

Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the expression, that is
12 - 1 = 11
12 - 2 = 10
12 - 3 = 9
12 - 4 = 8
The first 4 terms are 11, 10, 9, 8
The first four terms of the sequence defined by the expression 12-n are 11, 10, 9, and 8 when substituting the first four natural numbers for n.
The first four terms of the sequence defined by the expression 12-n can be determined by substituting the first four natural numbers for n. Let's calculate the first four terms of the sequence step-by-step.
For n = 1: 12 - 1 = 11
For n = 2: 12 - 2 = 10
For n = 3: 12 - 3 = 9
For n = 4: 12 - 4 = 8.
Therefore, the first four terms of the sequence are 11, 10, 9, and 8.

What are the advantages of using percentages to represent ratio
The advantages of using percentages are that they all are on the same scale (1/100) making it easier to work with compared to ratios.
We need to write the advantages of using percentages to represent the ratio.
What is the percentage?The percentage is a fraction or a ratio in which the value of the whole is always 100.
The percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Ratio: The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio.
The advantages of using percentages are that they all are to the same scale (1/100) making it easier to work with compared to ratios, they can be converted to decimals very quickly, and percentages can be used to show the change in a number (20% of 50: 50% of 10), telling you what the original number is (10:5 or 2:1 doesn’t give you the starting numbers).
