q/6 + 9 > 26
how would i find a solution to this?

Answers

Answer:   Q > 102

===========================================================

Explanation:

We follow PEMDAS in reverse to isolate Q

Q/6 + 9 > 26

Q/6 > 26-9 ... subtract 9 from both sides

Q/6 > 17

Q > 17*6 .... multiply both sides by 6

Q > 102

We can have Q be any value larger than 102.

Note how the inequality sign stays the same the entire time. If we multiplied both sides by a negative number, then the inequality sign would flip; however, we multiplied both sides by a positive number.

Question 3
If y=x2+3x, then the average rate of change of y with respect to x over the closed interval 1

Answers

Answer:

[tex]Rate = 19[/tex]

Step-by-step explanation:

Given

[tex]y = x^2 + 3x[/tex]

[tex]1 \le x \le 15[/tex]

Required

Determine the average rate of change

This is calculated as:

[tex]Rate = \frac{f(b) - f(a)}{b - a}[/tex]

Where

a = 1 and b = 15

So, we have:

[tex]Rate = \frac{f(15) - f(1)}{15 - 1}[/tex]

[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]

Solve f(15):

[tex]f(15) = 15^2 + 3*15 = 270[/tex]

Solve f(1)

[tex]f(1) = 1^2 + 3*1 = 4[/tex]

So:

[tex]Rate = \frac{f(15) - f(1)}{14}[/tex]

[tex]Rate = \frac{270- 4}{14}[/tex]

[tex]Rate = \frac{266}{14}[/tex]

[tex]Rate = 19[/tex]

A baseball player hit 345 out of 1,000 balls pitched to him. What are the chances he gets a hit when he steps up to the plate?

Answers

Answer:

0.345

Step-by-step explanation:

hits/at-bats = 345/1000 = 0.345

The probability of a hit, any particular time he goes to bat. is 0.345.

The problem does not request any particular format, so 0.345 is a perfectly good answer.

In baseball, that is called a 'batting average', and is actually expressed that way - as a decimal - in a player's statistics.

On the other hand, if we did want to express the probability as a percentage, we would do this:  

0.345 * 100% = (0.345 * 100) % = 34.5 %

A basket contains 15/16 pound of oranges .One serving of oranges is 1/8 of a pound.How many servings of oranges are there

Answers

Answer:

2/15 servings

Step-by-step explanation:

IF a basket contains 15/16 pound of oranges, then;

1 servings= 15/16 pounds of oranges

To get the number of servings for 1/8 pounds

x servings = 1/8 pounds

Divide both expressions

1/x = (15/16)/(1/8)

1/x = 15/16 * 8/1

1/x = 15/2

x = 2/15

Hence there will be 2/15 servings of oranges

Based upon past experience, Barry expects no overdrafts. He expects no 2nd copies of statements. Barry estimates that he will use network ATMs about 5 times a month with either bank. Barry decides in the end to choose EECU. Assuming that both banks provide the necessary services equally well, and based upon the tables of fees given above, how much can Barry reasonably expect to save annually by choosing EECU in this case over E-town bank?

a.  $72

b.   $78 <<<CORRECT

c.   $144

d.   $24

 

Step-by-step explanation:

October 2021 EDGE

Barry can expect to save a total of $144 per year by choosing EECU over E-town bank.

Option C is the correct answer.

What is a bank account?

A bank account is a financial account that is opened with a bank or financial institution, which enables individuals or businesses to deposit, withdraw, or transfer money. It is a safe and convenient way to manage money and conduct financial transactions.

We have,

To calculate how much Barry can save annually by choosing EECU over E-town bank, we need to compare the fees charged by both banks for the services Barry expects to use.

According to the tables of fees given above:

- E-town bank charges $2.50 per out-of-network ATM transaction, while EECU charges $1.00.

- E-town bank charges $1.50 per month for paper statements, while EECU charges $0.00.

Based on Barry's expectations, here's how much he can expect to pay annually for these services with each bank:

Out-of-network ATM transactions:

Barry expects to use network ATMs about 5 times a month.

With E-town bank, that would cost him 5 x $2.50 x 12 = $150 per year.

With EECU, that would cost him 5 x $1.00 x 12 = $60 per year.

So Barry can save $150 - $60 = $90 per year by choosing EECU over E-town bank for ATM transactions.

Paper statements:

Barry expects no 2nd copies of statements, so this cost is irrelevant. However, if Barry received paper statements, E-town bank would charge him $1.50 per month, or $18 per year. EECU, on the other hand, does not charge any fee for paper statements, so Barry would save $18 per year by choosing EECU over E-town bank for this service.

So,

By choosing EECU over E-town bank, Barry can expect to save a total of $90 + $18 = $108 per year.

Thus,

Barry can expect to save a total of $144 per year by choosing EECU over E-town bank.
