Answer:

24 drops of food coloring

Step-by-step explanation:

First, since there are 30 ounces, divide by 5, because there are 4 drops in every 5 ounces of icing. Since 30÷5=6, You have to multiply it by 4 to get 24. You multiply by 4 because there are 4 drops in 5 ounces of icing.

24 drops of food colouring are needed if you are using 30 ounces oficing.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Answer:

Step-by-step explanation:

If the sine is negative then theta must be in Quadrant III or Quadrant IV.

If the tangent is positive then theta must be in Quadrant I or III.

If both conditions must be satisfied, then we conclude that thera is in Quadrant III.

Note that [tex]\tan\theta=\frac{\sin\theta}{\cos\theta}.[/tex] Thus, if [tex]\sin\theta<0[/tex] and [tex]\tan\theta>0,[/tex] then we must have [tex]\cos\theta<0[/tex] as well. The sine function is negative when [tex]\theta[/tex] lies in Quadrant III or IV, and the cosine function is negative when [tex]\theta[/tex] lies in Quadrant II or III. Thus, the two are both negative when [tex]\theta[/tex] lies in Quadrant III, or [tex]\pi+2\pi n<\theta<\frac{3\pi}{2}+2\pi n[/tex] for integer values of [tex]n.[/tex]

Answer:

$220,000

Step-by-step explanation:

Given;

The annual median income for a registered nurse = $65,000

The annual median income for a registered dietitian = $54,000

The difference in the annual income of the registered dietitian from Nurse;

d = 65,000 - 54,000

d = $11,000

In 20 years, the cumulative difference in their earnings is;

Td = 20 × $11,000

Td = $220,000

Therefore, in 20 years the registered nurse will earn $220,000 more than the registered dietitian.

Answer:

Step-by-step explanation:

a) The formula for determining average is expressed as

Average point per game = number of points scored/total number of games played

Average point per game = 2857/1487 = 1.92

b) if he had played 79 more games, since his average point per game is 1.92, then the number of points that he might have scored would be

1.92 × 79 = 95 points

The total number of points would have been

2857 + 95 = 2952 points

Answer:

a. 1.92

b. 152

Step-by-step explanation:

Wayne Gretzky had 2857 points in 1487 games.

a. His average points per game can be determined by dividing the total number of points by number of games. So that:

average points per game = [tex]\frac{2857}{1487}[/tex]

                                          = 1.92132

Therefore, he scored an average of 1.92 (2 d.p) points per game.

b. The number of points he would have scored having played 79 more games can be determined by multiplying the points for 79 more games by his average points.

         His points for 79 more games = 79 × 1.92132

                                                            = 151.78428

He would have scored 152 (3 s.f) more points if he had played 79 more games.

Answer: x = 5

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.

Since 3 is being subtracted from 2x, we add 3

to both sides of the equation to isolate the 2x.

On the left, the -3 and +3 cancel

out and on the right, 7 + 3 is 10.

So we have 2x = 10.

No we can finish things off by just dividing

both sides of the equation by 2.

On the left the 2's cancel and on

the right, 10 divided by 2 is 5.

So we have x = 5.

✔ samples 1 and 2

Step-by-step explanation:

Linda randomly surveyed 20 teachers at her school about whether they prefer chalkboards or dry erase boards. She repeated the survey three times with three different sets of teachers.

A 3-column table with 3 rows. Column 1 has entries Sample 1, Sample 2, Sample 3. Column 2 is labeled Chalk with entries 12, 9, 1. Column 3 is labeled Dry Erase with entries 8, 11, 19.

Which pair of Linda’s samples seems to have the lowest variability and, therefore, are representative samples?
