Given that D(x) = 2x, select all of the following that are true statements. a- D(x) is a function,
b- xis the dependent variable,
c- D(6) = 3,
d- D(x) is a direct variation,
e- D(x) is a rule for the set of points (5, 10), (6, 12) and (-2, -4).

Answers

Answer 1
Answer: For D (x) = 2 x:
- x is the independent variable,
- D ( 6 ) = 2 · 6 = 12.
10 = 2 · 5,     12 = 2 · 9,     - 4 = 2 · ( - 2 ).
True statements are:
A ) D ( x ) is a function.
D ) D ( x )is a direct variation.
E ) D ( x ) is arule for the set of points ( 5, 10), ( 6, 12 )and ( -2, - 4 ).

Multiplying a number by which of the following would result in a smallest number? 10^-1 10^0 10^1 10^2

Answers

Answer:

To obtained the smallest number multiply the number with  (10)^(-1).

Step-by-step explanation:

Given : (10)^(-1),\ (10)^0,\ (10)^1,\ (10)^2

We have to find when we multiply any number with the given number which number will give the smallest value.

Consider the given numbers,

(10)^(-1),\ (10)^0,\ (10)^1,\ (10)^2

We find the values of each number one by one,

1) consider (10)^(-1), using property of exponents a^(-m)=(1)/(a^m), we have

(10)^(-1)=(1)/(10)=0.1

2) (10)^0 we know any thing to power 0 is always 1.

(10)^0=1

3) (10)^1 is same as itself that is 10.

4) (10)^2 is (10)* 10=100

Thus, To obtained the smallest number multiply the number with  (10)^(-1).

10^-1 would be the smallest answer...

10^-1= .1
10^0= 1
10^1= 10
10^2= 100

The manager of a video game store found that 35 of the 140 people who preordered the latest baseball game canceled their orders the day before the game was released. He used that data to create a simulation to predict the probability that future customers will cancel their preorders.

chart ,a table , or a graph

Answer: I believe this is unfinished. The rest of the question is:

According to the manager’s model, what is the probability that two customers who preorder the newest golf game will both cancel their orders the day before the game is released?

O 1/16

O 1/8

O 1/4

O 1/2

The answer to this question is 1/16.

Step-by-step explanation: Take the people that canceled their orders over the total number of people that ordered to get 35/140, which simplifies to 1/4. This problem is an independent event, so take 1/4 and multiply it by itself (1/4 times 1/4) to get 1/16.

A system of equations has no solution.If y=8x +7 is one of the equations,which could be the other equation has no solution.If y=8x +7 is one of the equations,which could be the other equation

Answers

Answer:

The other line is y= 8x - 7

Step-by-step explanation:

The given equation in two variable is

y= 8x ± 7

The two equations in two variables are:

Ax + By +C=0

P x + Q y +R=0

Now, the condition that these two equations has no solution is if;

A/P = B/Q ≠ P/R

Another condition is in terms of line , if the two lines have same slope.

For example, y= ax + b and , y = ax + p are two lines having same slope means they are parallel, that is they will never intersect.

If the line is , y = 8x + 7, the other line will be, y= 8x - 7

Answer: Y = 8X - 7

Step-by-step explanation:

A system of equations with no solution, means the two lines are parallel to each other.

If parallel to each other, they will have common gradient but different intercept.

A factory produces 90 packages of mixed nuts in 1 min. A quality control manager selected 8 of these 90 packages at random and then counted the number of nuts in each package. The manager recorded the results.31, 31, 32, 33, 35, 35, 35, 36

What is the estimated median number of nuts in all 90 packages?


________

Answers

Data set:

31, 31, 32, 33, 35, 35, 35, 36

Median is the middle value of the data set.

Since there is 8 numbers involved, the median is the average of the 4th and 5th number.

(33 + 35)/2 = 68/2 = 34

The median is 34.
