Final answer:

To calculate total gross pay, sum the hourly wage and tips earned. This sum represents the entire earnings before any deductions such as tax or social security are taken into account. Thus, option b is correct.

Explanation:

When calculating total gross pay, you should use your hourly wage and tips. The gross pay represents the total amount earned before any deductions, such as taxes or social security, are subtracted. To find the total gross pay, simply add the total amount of earned hourly wage to the amount received from tips.

For instance, if an employee receives $15 per hour and works for 8 hours and also earns $40 in tips, their gross pay for that day would be:

Hourly wage: $15/hour x 8 hours = $120

Tips: $40

So, the total gross pay would be $120 + $40 = $160 for that day.

So, option b is correct.

Final answer:

Jennifer is 66.3 inches tall; this is calculated by finding the z-score for the 70th percentile and using it with the mean and standard deviation of the population.

Explanation:

To determine how tall Jennifer is, given that she is taller than 70% of the population of U.S. women, we need to find the corresponding z-score that reflects the 70th percentile of a normal distribution, and then use it to calculate her height.

Firstly, using a standard normal distribution table or a calculator, we find the z-score that corresponds to the 70th percentile. Generally, this z-score is around 0.5244 (this can vary slightly depending on the table or technology used to find it). Now we apply the formula for converting a z-score to the actual score using the population mean and standard deviation:

Height = mean + (z-score × standard deviation)

Plugging in the values for the population mean and standard deviation:

Height = 65 + (0.5244 × 2.4)

Height = 65 + 1.2586

Height = 66.2586 inches

After rounding, we conclude that Jennifer is 66.3 inches tall.

In the given case, Jennifer's height is approximately 66.3 inches.

To find Jennifer's height, we need to find the z-score corresponding to the 70th percentile (as she is taller than 70% of the population) and then use that z-score to find her height.

The z-score formula is:

[tex]\[ z = \frac{x - \mu}{\sigma} \][/tex]

First, we find the z-score corresponding to the 70th percentile using a standard normal distribution table or calculator.

A z-score of approximately \(0.5244\) corresponds to the 70th percentile.

Now, we can use the z-score formula to find Jennifer's height x

[tex]\[ 0.5244 = \frac{x - 65}{2.4} \][/tex]

[tex]\[ x \approx 66.2586 \][/tex]

Rounded to one decimal place, Jennifer's height is approximately 66.3 inches.

Answer:

x = 2

y = 3

Step-by-step explanation:

y = 2x – 1

y - 2x = -1

y = 5x – 7

y - 5x = -7

y - 2x = -1

y - 5x = -7

_________--

3x = 6

x = 6/3

x = 2

y = 2x – 1

y = 2(2) - 1

y = 4 - 1

y = 3

[tex]x=2\\y=3[/tex]

Given -

[tex]y=2x-1\\y=5x-7[/tex]

So, substitute [tex]y=2x-1[/tex] in [tex]y=5x-7[/tex].

[tex]y=5x-7\\2x-1=5x-7\\5x-2x-7+1=0\\3x-6=0\\3x=6\\x=\frac{6}{3} \\x=2[/tex]

Now, substitute [tex]x=2[/tex] in [tex]y=2x-1[/tex].

[tex]y=2x-1\\y=2(2)-1\\y=4-1\\y=3[/tex]

Therefore, [tex]x=2[/tex] and [tex]y=3[/tex].

I think the answer is 3,053.628.

Answer:

3050

Step-by-step explanation:

V=4 /3xπxr/\3=4

3·π·93≈3053.62806

1/10 or 10%.

First, you add up all the quarters to get the total amount of possibilities for the first quarter that gets pulled out.

4 NY + 3 PA + 3 VI = 10 total quarters.

So the total number of quarters becomes the denominator for the first probability, and the total number  of PA quarters becomes the numerator.

So the probability of Jim pulling out a PA quarter first is 3/10.

Now you have to find the probability of drawing a VI quarter as the second quarter. Since it's known that Jim would have already pulled 1 quarter out, that means the total number of quarters he could draw is now 9, so 9 would be the denominator of the second probability. Since there should be 3 VI quarters left still in his pocket, the numerator for the second probability is 3.

So the probability of Jim pulling out a VI quarter second is 3/9.

Now to get the final probability of Jim pulling out both a PA quarter and a VI quarter in the correct order, all you have to do is multiply the two probabilities together and then you should get the probability of the correct quarters being pulled out inn the correct order.

The first probability, 3/10, times the second probability, 3/9 equals the total probability of 9/90, and it simplifies to 1/10 or 10%

Answer:

3.2 x 10^5

Step-by-step explanation:

Scientific Notation

3.2 x 10^4 = 32000

3.2 x 10^5 = 320000

Final answer:

The number 3.2 x 10⁵ is larger than 3.2 x 10⁴ because it represents 320,000, compared to 32,000 which is represented by 3.2 x 10⁴. The exponent indicates the number of zeroes to follow the digit.

Explanation:

To determine which number is larger between 3.2 x 10⁴ and 3.2 x 10⁵, we need to understand the notation being used. In scientific notation, the number 10 raised to an exponent indicates how many places to move the decimal point. The larger the exponent, the larger the value.

For 3.2 x 10⁴, it means we have a 3.2 followed by 4 zeros, which is equal to 32,000. In contrast, 3.2 x 10⁵ means we have a 3.2 followed by 5 zeros, which is equal to 320,000. Clearly, 320,000 is larger than 32,000.

Thus, 3.2 x 10⁵ is larger than 3.2 x 10⁴.

The radius is 3.3 and the height is 21

V = pi (3.3)^2 * 21

V = pi (10.89) (21)

V =pi 228.69

We can approximate pi by 3.14

V = 3.14(228.69)

V =718.0866 in^3

Answer:

x = 6

x = 16

y = 11

Step-by-step explanation:

Honestly you're not going to read this part but eh.

13x - 5 = 7x + 31 (because bisect means these two angles are congruent)

6x = 36 (combined like terms)

x = 6 (divided by 6)

Didn't read this either but eh again.

5x - 4 + 7x - 8 = 180 (because supplementary angles)

12x - 12 = 180

12x = 192

x = 16

Plug in to find y:

9y + 5 = 7(16) - 8

9y + 5 = 104

9y = 99

y = 11

option B

The Volume of Cone is 392π unit³.

The correct option is (B).

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

We have,

l = 25

Radius = 7 unit

Height = 24 unit

So, the Volume of cone

= 1/3 πr²h
