Joshua, an editor for the Winston Salem Gazette, edits 1⁄6 of a page in 3 minutes. How long would it take him to edit 3 pages?

Answers

Answer:

54

Step-by-step explanation:

If we know that Josh edits at a rate of 1/6 of a page in three minutes... then using the Unit rule... we can determine that he edits 1 whole page 6 times longer than that. By doing that... we find that Josh edits 1 page in 18 minutes. From there... we multiply the time at which it takes him to edit one page (18 minutes) by 3 (pages) to get our answer.

18 x 3 = 54

Find the value of StartFraction partial derivative z Over partial derivative x EndFraction at the point​ (1,1,1) if the equation 5 xy plus z Superscript 4 Baseline x minus 3 yz equals 3 defines z as a function of the two independent variables x and y and the partial derivative exists.

Answers

Looks like the given curve is

5xy + zx - 3yz = 3

Differentiate both sides with respect to x :

5y + 4z³xz/∂x + z⁴ - 3yz/∂x = 0

Solve for ∂z/∂x :

(4z³x - 3y) ∂z/∂x = - (5y + z⁴)

z/∂x = - (5y + z⁴) / (4z³x - 3y)

At the point (1, 1, 1), this derivative is

z/∂x (1, 1, 1) = - (5 + 1) / (4 - 3) = -6

We need to multiply the percentage as a decimal (0.30) with the amount of chocolate (50 g):

0.30*50 = 15 g

There are 15 grams of cocoa in the chocolate bar.  

Answer:  15 grams of cocoa

Work Shown:

30% = 30/100 = 0.30

30% of 50 = 0.30*50 = 15

Here's another way to think about it: If we had 100 grams of chocolate and 30% are cocoa, then we have 30 grams of cocoa by definition of what percentage means. Divide the 100 in half to get 50, so we'll have to divide the 30 in half to get 15.

In ΔXYZ, the measure of ∠Z=90°, ZY = 4, XZ = 3, and YX = 5. What ratio represents the tangent of ∠X?

Answers

Answer:

[tex]tan\ X= \frac{4}{3}[/tex]

Step-by-step explanation:

Given

[tex]Z=90\°[/tex]

[tex]ZY = 4[/tex]

[tex]XZ = 3[/tex]

[tex]YX = 5[/tex]

Required

Determine tan x

This question can be illustrated using the attached image

Tan of an angle is calculated as:

[tex]tan \theta = \frac{Opposite}{Adjacent}[/tex]

In this case, it is:

[tex]tan\ X= \frac{ZY}{XZ}[/tex]

Substitute values for ZY and XZ

[tex]tan\ X= \frac{4}{3}[/tex]

Hence, the required ratio is 4/3

Students at a liberal arts college study for an average of 10 hours per week with a standard deviation of 2 hours per week. The distribution of their study time happens to be uni-modal, symmetric and bell shaped. Approximately 68% of students study between 8 and B hours a week. What is the value of B

Answers

Answer:

it lies between 8 hours and 12 hours in a week  

Step-by-step explanation:

Since in the question it is mentioned that the distribution consist of uni-modal, symmetric and bell shaped so here the empirical formual to be used for the mean and the standard deviation

Also the 68% would be fall within one standard deviation above and below the mean

Now

1 standard deviation below the mean is

[tex]= \mu - \sigma[/tex]

= 10 - 2

= 8 hours

And, above the mean is

[tex]= \mu + \sigma[/tex]

= 10 + 2

= 12 hours

Hence, it lies between 8 hours and 12 hours in a week
