Answer:

The correct answer is given by option A.

Step-by-step explanation:

A function is said to be increasing for intervals of x in which the values of y are increasing, that is, it trends upwards, and decreasing for intervals of x in which the values of y are decreasing, that is, it trends downwards.

In this question:

It trends upwards from the start, at negative infinity, until 0.

It trends downwards from 0, until the end, at positive infinity.

So the correct answer is given by option A.

Answer:

Option (2) and Option (6)

Step-by-step explanation:

Expression representing the error can be given by,

Expected value = Original value ± percentage error

If original value of the ice cream filled in the container = 64 ounce

Percentage error to fill the ice cream in each container = 1.5%

So net error = ± 1.5% of 64

                    = [tex]64(\frac{1.5}{100})[/tex] ounce

                     = 64(0.015) ounce

Therefore, expression that can show the maximum maximum amount of ice cream in the container will be

= 64 + 64(0.015) Option (6)

= 64(1 + 0.015)

= 64(1.015) Option (2)

Therefore, Option (2) and Option (6) are the correct options.

Malik earns an average of 412 points on his daily quizzes. Near the end of the quarter, his average decreases by 34 points.


Write and then evaluate a subtraction expression (in fraction form) to find his current quiz grade average.

Answers

Answer: Required expression= 412-34

Current quiz grade average = 378

Step-by-step explanation:

Given: The average points on daily quizzes = 412

The average decreases by 34 points.  (Near the end of the quarter)

Current quiz average = (Average points on daily quizzes) - (Average decreases)

i.e. Current quiz average =412-34  [ i.e. Required expression= 412-34]

i.e.  Current quiz average =378

Hence, his current quiz grade average = 378

The oldest child in a family of four children is twice as old as the yougest. The two middle children are 12 and 16 years old. If the average age of the children is 15.25 , how old is the youngest child?

Answers

four children average is 15.25 so ages must add to 61
61-12-16=33
11 and 22 go into 33
Youngest is 11

The age of the youngest child will be 11 years old.

What is the solution to the equation?

The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.

The oldest child in a family of four children is twice as old as the youngest.

Let x be the age of the youngest child and y be the age of the oldest child. Then the equation is given as,

y = 2x   ...1

The two middle children are 12 and 16 years old. If the average age of the children is 15.25. Then the equation is given as,

(x + 12 + 16 + y) / 4 = 15.25

x + y = 33  ...2

From equations 1 and 2, then we have

x + 2x = 33

3x = 33

x = 11

The age of the youngest child will be 11 years old.

Step-by-step explanation:

Two candles were lit and are burning. Candle A has
an initial height of 10 inches and burning down at a
rate of 1.5 inches per hour. Candle B is burning down
at a rate of 0.5 inches per hour and has an initial
height of 6 inches. Let t represent time in hours and
h represent the total height of the candle.

Answers

Answer:

A - 6 hours and 40 minutes

B - 12 hours

Step-by-step explanation:

Candle A - After 6 hours: the candle will be 1 inch tall, because 6 times 1.5 = 9. You need an extra 40 minutes for the candle to burn completely, because 10/1.5 = 6 and 2/3

Candle B - After 12 hours, the candle will be completely burned, because 6/.5 = 12.

Equation - Initial height/inches burned per hour = time it takes for cnadle to burn down completely

Pollsters are concerned about declining levels of cooperation among persons contacted in surveys. A pollster contacts 99 people in the 18-21 age bracket and finds that 84 of them respond and 15 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 257 respond and 19 refuse to respond. Assume that 1 of the 375 people is randomly selected. Find the probability of getting someone in the 18-21 age bracket or someone who agreed to respond.

Answers

Answer:

The probability of getting someone in the 18-21 age bracket or someone who agreed to respond [tex]= 0.365[/tex]

Step-by-step explanation:

The counts are as follows  

Age Group  No of people contacted No of refusals      Total  

18-21               88                                  8                       96

22-29              240                                  42                       282

Total              328                                  50                       378

 

The probability of getting some one in the age bracket of 18-21 or some one who refused to respond is

[tex]= \frac{96}{378} + \frac{50}{378} - \frac{8}{378} \\= \frac{96+50-8}{378} \\= \frac{138}{378} \\= 0.365[/tex]

Answer:

Mean - 79

Median- 81

Range- 11

Step-by-step explanation:

Mean aka average = add all the numbers together and divide it by the number of numbers there were to find the mean of something.

in this case  : 81 + 82 + 84+ 75+73+75 + 83 = 553 divided by 7 = 79

Median -  Rearrange the set of numbers from least to greatest or  greatest to least  and find the middle number to find the median

In this case : 73, 75, 75, 81, 82, 83, 84 =  The median is 81

Range - Substract the highest and the lowest number from the set of numbers to find the range.

In this case : 84 - 73 = 11

Forty percent of the students who enroll in a statistics course go to the statistics laboratory on a regular basis. Past data indicates that 55% of those students who use the lab on a regular basis make a grade of A in the course. On the other hand, only 15% of students who do not go to the lab on a regular basis make a grade of A. If a particular student made an A, determine the probability that she or he used the lab on a regular basis. (Round your answer to three decimal places.)

Answers

Answer:

0.71 = 71% probability that she or he used the lab on a regular basis.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Student got an A

Event B: Used the lab on a regular basis.

Probability of an student getting an A:

55% of 40%(go to the lab on a regular basis).

15% of 100 - 40 = 60%(do not go to the lab on a regular basis).

So

[tex]P(A) = 0.55*0.4 + 0.15*0.6 = 0.31[/tex]

Probability of getting an A and using the lab on a regular basis:

55% of 40%, so:

[tex]P(A \cap B) = 0.55*0.4 = 0.22[/tex]

Probability that she or he used the lab on a regular basis.

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.22}{0.31} = 0.71[/tex]

0.71 = 71% probability that she or he used the lab on a regular basis.
