Step-by-step explanation:
A biology test is worth 100 points and has 36 questions.
a. Multiple-choice questions are worth 2 points each and essay questions are worth 6 points each. How many questions of each type are on the test?
b. Your friend says that it is possible for the multiple-choice questions to be worth 4 points each. Is your friend correct? Explain.
Answer:
(a) 7 essays and 29 multiple questions
(b) Your friend is incorrect
Step-by-step explanation:
Represent multiple choice with M and essay with E.
So:
[tex]M + E= 36[/tex] --- Number of questions
[tex]2M + 6E = 100[/tex] --- Points
Solving (a): Number of question of each type.
Make E the subject of formula in [tex]M + E= 36[/tex]
[tex]E = 36 - M[/tex]
Substitute 36 - M for E in [tex]2M + 6E = 100[/tex]
[tex]2M + 6(36 - M) = 100[/tex]
[tex]2M + 216 - 6M = 100[/tex]
Collect Like Terms
[tex]2M - 6M = 100 - 216[/tex]
[tex]-4M = - 116[/tex]
Divide both sides by -4
[tex]M = \frac{-116}{-4}[/tex]
[tex]M = 29[/tex]
Substitute 29 for M in [tex]E = 36 - M[/tex]
[tex]E = 36 - 29[/tex]
[tex]E = 7[/tex]
Solving (b): Can the multiple questions worth 4 points each?
It is not possible.
See explanation.
If multiple question worth 4 points each, then
[tex]2M + 6E = 100[/tex] would be:
[tex]4M + xE = 100[/tex]
Where x represents the number of points for essay questions.
Substitute 7 for E and 29 for M.
[tex]4 * 29 + x * 7 = 100[/tex]
[tex]116 + 7x = 100[/tex]
Subtract 116 from both sides
[tex]116-116 + 7x = 100 -116[/tex]
[tex]7x = 100-116[/tex]
[tex]7x = -16[/tex]
Make x the subject
[tex]x = -\frac{16}{7}[/tex]
Since the essay question can not have worth negative points.
Then, it is impossible to have the multiple questions worth 4 points
Your friend is incorrect.
The test contained 29 multiple choice questions and 7 essay questions.
Let x represent the number of multiple questions and y represent the number of essay questions.
Given that there are a total of 36 questions, hence:
x + y = 36 (1)
Also, the test is worth a total of 100 points, hence:
2x + 6y = 100 (2)
Solving equation 1 and 2 simultaneously gives:
x = 29, y = 7
Therefore the test contained 29 multiple choice questions and 7 essay questions.

Four of you enter in the race. You are told that only one will complete the course. What is the probability if you complete the Course. What is probability that you will not complete the course.
Answer:
25% probability that you complete the course
75% probability that you do not complete the course
Step-by-step explanation:
If there are a total of 4 individuals entering the race and only one is able to complete the course then the probability that you will complete the course would be
1/4 = 0.25 or 25%
This is because you only represent 1 out of the 4 total participants. The opposite would be the case to calculate the probability that you will not complete the course since there are three other candidates with that could have completed it, therefore...
3/4 = 0.75 or 75%

a cyclist rode 3.75 miles in 0.3 hours how fast was she going in miles per hour?
Answer:
12.5 miles per hour
Step-by-step explanation:
Math
Answer:
12.5 MPH
Step-by-step explanation:
Miles per hour can also be written as miles/hour
therefore 3.75 miles in .3 hours can also be written as 3.75 miles/.3 hours
3.75 / .3 = 12.5
Therefore the cyclist was going 12.5 miles per hour
A piece of machinery depreciates $6000 the first year,
$5700 the second year, and $5400 the third year. If the
rate of depreciation is constant, what is the amount of
depreciation of the piece of machinery in the sixth year?
Answer:
$4500
Step-by-step explanation:
it decreases $300 per yeae
Based on the rate of depreciation each year, the amount of depreciation of the machinery in the sixth year will be $300.
What is the annual depreciation amount?The depreciation in the second year is:
= 6,000 - 5,700
= $300
The depreciation in the third year is:
= 5,700 - 5,400
= $300
If this amount remains constant till the sixth year therefore, then it means that the sixth year depreciation amount is also $300.

Answer:
Step-by-step explanation:
1.8kg into grams
1.8kg = 1800 grams
Total toys = 6
Weight of one toy = 1800 ÷ 6 = 300 grams
Weight of 4 toys = 300 x 4 = 1200 grams = 1.2kg
Answer:
Step-by-step explanation:
a) 1 Kg = 1000 grams
1.8 Kg = 1.8 * 1000 = 1800.0 = 1800 grams
b) Weight of one toy = Weight of all the 6 toys ÷ 6
= 1800 ÷ 6
= 300 grams
c) Weight of 4 toys = 4 * 300

Answer: c
Step-by-step explanation:
look at the equation and insert the value of X from the table into the equation and figure out which one will give you the same sum for the values. for example f(x) = 3(-2)-1
this answer gives you f(x)= -6 -1 which will give u a sum of -7
another one : f(x)= 3(0)-1
3 multiplied by 0 gives you 0 therefore you are left with -1
by doing this you prove that this equation works with ur x values and gives you the same sum you have for f(x)

A train travels at an average speed of 67.5 at this speed how far could the train travel in 3.25 hours
Answer:
219.375
Step-by-step explanation:
Speed = distance / time
67.5 = distance / 3.25 hours
Multiply both sides by 3.25
67.5 x 3.25 = 219.375
Answer:
The Train Could travel 219.375 MPH
Step-by-step explanation:
Since the train travels at a speed of 67.5 miles per hour, multiply 67.5 by 3.25.
67.5 × .25 = 16.87567.5 × 3 = 202.516.875 + 202.5 = 219.375

The probability of event A occurring is 0.65. The probability of events A and B occurring together is 0.33. Events A and B are independent. What is the probability of event B?
Enter a number to the nearest hundredth.
Answer:
Approximately 0.51
Step-by-step explanation:
If events A and B are independent, then P(A and B) = P(A)*P(B) is a true equation.
We're given the following
P(A) = 0.65
P(A and B) = 0.33
So,
P(A and B) = P(A)*P(B)
0.33 = 0.65*P(B)
P(B) = 0.33/0.65
P(B) = 0.5076923076923
which is approximate. When we round to 2 decimal places, we get 0.51

which set of values could be the side lengths of a 30 60 90 triangle?
Answer:
b
Step-by-step explanation:
A salesperson works 40 hours per week at a job where he has two options for being paid. Option A is
an hourly wage of $22. Option B is a commission rate of 4% on weekly sales. How much does he
need to sell this week to earn the same amount with the two options?
thank you so much!
His salary for 40 hours per week with an hourly rate is hours x the rate:
40 hours x $22 per hour = $880 per week.
If he is paid commission, to make the same , he needs to make $880 iin commissions.
The commission rate is 4%, to find how much sales is needed divide the amount he needs to make ( $880) by the rate:
880/ 4% = 880/ 0.04 = $22,000
He needs to sell $22,000

Answer:
a merchandising business because it resells clothes at retail prices
Step-by-step explanation:
This is a merchandising business because Adele buys clothes at one price and resells them at a higher retail price.
For the 2012-2013 National Hockey League and National Basketball Association seasons,
two hockey tickets and one basketball ticket purchased at their average rates cost $173.01.
One hockey ticket and two basketball tickets cost $162.99, when purchased at their
average rates. What were the average ticket prices for the two sports?
The average cost for an National Hockey League ticket was $____
The average cost for an National Basketball Association ticket was $____
9514 1404 393
Answer:
Hockey: $61.01Basketball: $50.99Step-by-step explanation:
Using h and b to represent the prices of hockey and basketball tickets, respectively, the two purchases are ...
2h +b = 173.01
h +2b = 162.99
Subtracting the second equation from twice the first gives ...
2(2h +b) -(h +2b) = 2(173.01) -(162.99)
3h = 183.03
h = 61.01
Substituting that into the first equation, we can solve for b:
b = 173.01 -2h = 173.01 -2(61.01)
b = 50.99
The average cost of an NHL ticket was $61.01.
The average cost of an NBA ticket was $50.99.
