7. 23% of the class was unhappy. 19 students were unhappy. How many students were in the class? Round to the nearest student.

Answer:

$1.03

Step-by-step explanation:

If Seth purchased a shiny key chain costing $0.34 and received $0.69 in change, then he gave the cashier $0.34 + $0.69 = $1.03.

Answer:

x - 0.69 = 0.34

x = 1.03

Therefore, Seth gave the cashier $1.03.

Answer:

5/12

Step-by-step explanation:

Find the LCM for denominators 3 and 4, this would be 12.

[tex]\frac{1*3}{4*3} = \frac{3}{12}[/tex]

[tex]\frac{1*4}{3*4} = \frac{4}{12}[/tex]

Add both fractions together:

3/12 + 4/12 = 7/12

Subtract 7 from 12 to find the remaining amount to make 12:

12 - 7 = 5

Therefore, the fraction that remains for other expenses is [5/12]

The inverse of the function is g(x) = √[(x + 3)/4]

From the question, we have the following parameters that can be used in our computation:

f(x) = 4x^2 - 3

Rewrite the function as

y = 4x^2 - 3

Swap the variables

x = 4y^2 - 3

Make y the subject

So, we have the following representation

y = √[(x + 3)/4]

Rewrite as

g(x) = √[(x + 3)/4]

Hence, the inverse is g(x) = √[(x + 3)/4]

If your original biconditional statement is true, would the contrapositive be true

What is Biconditional statement ?

Biconditional statement can be defined as if in both cases they are equal than they are true otherwise false.

Yes,

If your original biconditional statement is true, would the contrapositive be true

Let us suppose,

P ⇔ Q

Suppose P = true and Q = true

So, P ⇔ Q  is true

and ~P = false and ~Q  = false

¬Q ⇔ ¬P is also true
Therefore, If your original biconditional statement is true, would the contrapositive be true

7/3 in four different ways is 7/12

Division is the opposite of multiplication. If 3 groups of 4 make 12 in multiplication, 12 divided into 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in each group when sharing fairly.

If 100 apples are to be shared by 20 girls equally. The number of apple each girl will get is 100/20 = 5 apples each.

Similarly to put 7/3 in four different ways we have to divide 7/3 by 4

7/3 ÷ 4 = 7/3 × 1/4

= 7/12

therefore 7/12 of the four places will give 7/3

If you would like to have $500,000 when you retire in 30 years.
a. Amount earned  $2,322.76.

b. Total money  $2,322.76

c. Total interest earned $225,268.80

a) To calculate the amount you need to deposit each quarter to reach $500,000 in 30 years, you can use the formula:

P = A / (1 + r/n)^(nt)

P = $500,000 / (1 + 0.066/4)^(4 * 30)

P = $2,322.76

b) Total money

 Total money = $2,322.76 * 4 quarters/year * 30 years

Total money = $2,322.76

c) Total interest earned

Total interest earned = $274,731.20 - $500,000

Total interest earned = $225,268.80

Therefore the amount earned is  $2,322.76.

The result of 2/3 divided by 1/12 is equal to 8.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

To find the result of 2/3 divided by 1/12, we can use the following equation:

= 2/3 ÷ 1/12 = (2/3) × (12/1)
= 8

Since the multiplication of two numbers is equivalent to the division of their reciprocals, we can use the number line to represent the division as multiplication:

2/3 is located between 1/2 and 1 on the number line, and 1/12 is located between 0 and 1/10. Multiplying 2/3 by 12/1 is the same as moving 12 units to the right on the number line, which is equivalent to moving from 2/3 to 8.

So, the result of 2/3 divided by 1/12 is equal to 8.

C. a quadratic function with a negative value of a

Step-by-step explanation:

It is likely that a quadratic function with a negative value of a would be the best model for this data, as it would represent a parabolic shape that can accommodate a downward trend, followed by an upward trend, in the stock price. The value of "a" determines the direction of the parabola, with a negative value resulting in a downward-facing parabola, which is appropriate for a stock price that starts low and increases over time. This type of function would provide a good fit for the data, especially if there are fluctuations or ups and downs in the stock price over time.
