Answer 1

Answer:

The answer is

15

Step-by-step explanation:

[tex]w(t) = - 2t + 1[/tex]

To find w(- 7) substitute the value of t that's - 7 into w(t) that's for every t in w(t) replace it with - 7

That's

[tex]w( - 7) = - 2( - 7) + 1 \\ = 14 + 1[/tex]

In the class election, the student who gets the highest number of votes will become the class president and the one who gets the second highest
number of votes will become the class vice president. Tabitha and four other students were candidates. Tabitha's teacher announces the election
results as percentages of the total number of votes. Two hundred votes were cast in the election. In this activity, you will relate the percentages of
the votes received to the actual numbers.
Question 1
The table gives the percentage of votes each candidate received. Use the information in the table to understand the results of the election
Candidate Percentage of Votes
Tabitha
30%
Vincent
12%
Esmeralda
22%
Nancy
5%
Tyler
31%
Part A
How many votes did Tabitha receive?

Answers

Answer:

Tabitha received 60 votes.

Step-by-step explanation:

200 votes × .30 = 60 votes

The given percentage of votes shows that Tyler win the class elections (has the highest percentage of votes - 31%), and Tabitha received 60 votes (30% of 200).

What are percentages?

A percentage is a fraction of a whole number represented as a number out of 100.

How do we solve the given question?

We are given the percentages of votes received by the candidates in a class election. We are also informed that a total of 200 votes were cast in the elections.

The percentages are as follows:

Tabitha = 30%

Vincent = 12%

Esmeralda = 22%

Nancy = 5%

Tyler = 31%.

We are asked to find the winner of the election and the number of votes Tabitha received.

As Tyler receives the highest percentage of votes (31%), he is the winner of the elections.

Tabitha received 30% of the votes, and the total number of votes = 200

∴ Number of votes Tabitha received = 30% of 200 = (30/100)*200 = 0.3*200 = 6.

∴ Tabitha received a total of 60 votes.

The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13. According to the standard deviation rule, only (what?) % of people have an IQ over 126.

Answers

Answer: 2.5% of people have an IQ over 126.

Step-by-step explanation:

Given: The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 13.

126 = 100 + 2(13) = Mean +2 ( standard deviation)

To find : % of people have an IQ over 126.

i.e. % of people have an IQ over Mean +2 ( standard deviation).

According to the standard deviation rule,

95% of data fall within two standard deviations.

Now, 100% - 95% = 5%

and Half of 5% is 2.5%.

So 2.5% of the data lies below 2 standard deviations of mean and 2.5% of the data lies above 2 standard deviations of mean .

i.e.  2.5% of people have an IQ over 126.

Valleywood Golf course offers classes Monday through Saturday. The Saturday classes last 75 minutes. If they offered 705-minutes of classes last week, what was the maximum number of weekday classes?

Answers

Answer:

Step-by-step explanation:

To make the problem easier to solve, we will set it up as the equation of the length of time of each class times the number of classes equals the total amount of minutes. However, since we don't know the number of classes, we'll symbolize our two unknowns with two variables.

75x + 45y = 705

(75x + 45y)/15 = 705/15

5x + 3y = 47

y = (47-5x)/3

It looks like we can't simplify the equation any more, so now it is a matter of trial and error. The minimum number of Saturday classes means the maximum number of weekday classes. We first will test for the maximum by assuming there are no Saturday classes, then will work our way up until x is an integer.

If x = 0

(47-5(0))/3 = 47/3 = 15.6666

If x = 1

(47-5(1))/3 = 42/3 = 14

This works. Therefore, the maximum number of weekday classes is 14, or choice b.

The sum of three consecutive integers is 180. What is the largest integer?

Answers

Answer:

61

Step-by-step explanation:

Here's a neat trick when you have an odd number of consecutive numbers.

Call the middle number k

Then the smaller number is k-1

The larger number is k + 1

The two ones will cancel.

k-1 + k + k-1 = 180

3k = 180

k = 180/3

k = 60

Therefore the largest number is k + 1 = 60 + 1 =61

A bag contains 8 green, 4 black and 6 yellow marbles. How could you use the complement to determine the probability of randomly selecting a green or black marble?

Answers

Answer:

12/18=2/3

Step-by-step explanation:

You should add up every marbles to find out how many marbles are in total. Then, you should add the green and black marbles. There are 4 black marbles, and 8 green marbles, which results 12 black+green marbles. Then you should make a fraction 12/18, because you are finding the probability of the green+black marbles out of the total marbles. If you simplify, you get 2/3.

The probability of randomly selecting a green or black marble is 12/18.

What is probability?

Probability is the ratio that determines how likely an event is to occur from a set of possible events.

We can find the probability of randomly selecting a green or black marble as shown below:

Total number of green marbles = 8

Total number of black marbles = 4

Total number of yellow marbles = 6

Total number of marbles = Total number of green marble + Total number of black marbles + Total number of yellow marbles = 18

P(selecting a green marble) = Total number of green marbles/Total number of marbles

= 8/18

P(selecting a black marble) = Total number of black marbles/Total number of marbles

= 4/18

P(selecting a green or black marble) = (Total number of green marbles + Total number of black marbles)/Total number of marbles

= (8 + 4)/18

= 12/18

Therefore, we have found the probability of randomly selecting a green or black marble to be 12/18.

The cost of 1.00 Liters of gas is 26.9 cents. How many dollars will 12.0 gallons cost?

Answers

12 gallons = 45.425 liters. (You can divide 45.425 and 12 to get how many gallons are in one liter.) If one liter = 26.9 cents, then we would multiply 45.425 by 26.9. This equals 1,221.9325 cents. That would be about 12 dollars and 22 cents.

The cost of 12 gallons of gas will be 1221.80 cents.

It is given that 1 liter of gas cost 26.9 cents.

We have to calculate the cost of 12 gallons of gas.

What will be the cost of 10 pens if 1 pen costs 2 cent ?

The cost of 10 pens will be 10 × 2 = 20 cent.

As per the question ;

Cost of 1 liter of gas = 26.9 cent

1 gallon = 3.785 liters

So ,

The cost of 1 gallon of gas = 3.785 × 26.9

The cost of 12 gallons of gas will be ;

= 12 × 3.785 × 26.9

=  1221.80 cents

Thus , the cost of 12 gallons of gas will be 1221.80 cents.

Answer:

20.25

Explanation:

We first need to find the length of one side of the square. We can do this by dividing the area by 4 (27/4), since a square has four sides. You should get 6.75. Now you can multiply 6.75 by three since one side of the square is the same as one side of the triangle. Also, it is an equilateral triangle and all sides are the same. If you multiply correctly, you should get 20.25. Hope this helped!

Answer:

9 sqrt(3)

Step-by-step explanation:

Since the area of the square is 27 cm^2

A = s^2

27 = s^2

Take the square root of each side

sqrt(27) = s

sqrt(9) sqrt(3) = s

3 sqrt(3) =s

We know the the side length of the triangle is s

The perimeter of the triangle is

P =3s = 3 ( 3 sqrt(3))
