Explanation

When two expressions are not equivalent, you can use an inequality symbol

now, when comparing two expressions that are equivalent , WE CAN NOT USE an inequality simbol, instead of we need to use The equals sign or equal sign formerly known as the equality sign

for example

the = symbold indicates that both sides have the same value ( rigth and left)

I hope this helps you

Given the function:

Where A is the amount of money (in dollars) Diane has left in her account after t trips on the toll roads.

(a)

After 8 trips on the toll roads (t = 8):

(b)

If her account is empty:

Solving the equation for t:

Given that 11v - 8 = 3

add 8 to both sides

11v = 3 + 8

11v = 11

Divide both sides by 11

v = 1

to simplify 4v - 8

= 4 (1) - 8

= 4 - 8

= -4

Given Data:

The upstream speed is, 25 miles/hr.

The downstream speed is, 35 miles/hr.

The total time is, 12 hr.

Let d be the distance traveled. He can travel 25 miles/ hr in upstream, so the time taken will be,

He can travel 35 miles/ hr in upstream, so the time taken will be,

Total time is, 12 hr. So we have,

Therefore the total distance is, 350 mile

Given that:

Cost of the washer/dryer = $900

To be a function, it is nesessary that the values of x correspond to a unique value of y (a value of x cannot correspond to 2 different values of y). The same value of y can correspond to two or more values of x

As in the given data each value of x has just one value of y. Then, it is a function.

Answer:

The answer will be A) 1847

Answer:

Explanation:

Here, we want to get the amount of money that would guarantee that a person has more money than 80%

That means the probability is greater than 80% or 0.8

Thus, we need to get the z-score that corresponds to this probability

Using a z-score table, we can get this as follows:

We will now get the value from the obtained z-score

Mathematically:

Substituting the values, we have it that:

Answer

11,232,000 possible license tags.

Explanation

The licenses have space for 6 characters.

We need to note that there are 26 alphabets and 10 numbers to pick from.

So, for the first character, any of the 26 alphabets can take this spot.

For the second character, 25 alphabets are now available for that space. (Since repetition is not allowed)

For the third character, 24 alphabets are available for that.

For the fourth character, any of the 10 numbers can take up that spot.

For the fifth character, only 9 numbers can take this spot now. (No repetition rule too)

For the sixth character, 8 numbers can take that spot.

So, mathematically, the number of license tags possible will be

26 × 25 × 24 × 10 × 9 × 8 = 11,232,000 possible license tags

Tyrone randomly interviewed 55 8th graders at the Westwood Mall Saturday afternoon to determine their reason for going to the mall.

Based on the results he made the following claim.

"Two out of four middle school students visit the mall to go shopping".

Let us analyze each of the given options.

a. Tyrone only interviewed students in the food court.

There is no evidence that suggests the interview was conducted at the food court so this is not the correct answer.

b. Tyrone did not survey enough 8th graders to draw a valid conclusion

He interviewed 55 8th graders which are more than enough students so this is not misleading.

c. Tyrone did not use a random sample of 8th graders

It is given in the question that he used a random sample so this is not misleading.

d. Since Tyrone surveyed only 8th graders, his sample is not representative of all middle school students.

If you notice closely, Tyrone interviewed only 8th graders whereas the claim was about all middle school students.

So this is clearly misleading, 8th graders do not represent all middle school students.

Therefore, option d is correct.

Solution

Given

According to the second inequality, y is greater than or equal to -2, which means that the graph will have a solid line, the first step is to pick solid choice.

The boundary line is y=2, we know this by replacing the inequality sign by an equal sign. Two points one this line are (-1,2) and (2,2). We know it because it is an horizontal line that represents a constant function, it means that all the values of y will be 2 (boundary line).

As the equal sign is greater than or equal to, the region that must be shaded is the one above the boundary line.

Solution:

To graph, a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equals sign. The graph of this equation is a line.

If the inequality is strict ( < or > ), graph a dashed line. If the inequality is not strict ( ≤ and ≥ ), graph a solid line.

For example,

Consider the linear inequality in two variables below

Step 1:

Put x=0 and find y

Step 2:

Put y=0 and find x

Hence,

We are going to use the coordinates below to graph the inequality using a solid line because

The inequality sign used is greater than or equal to

Hence,

The graph of the inequality will be
