How many degrees does the hour hand move from 3:00 to 5:30?
hodyreva [135]

now, keeping in mind that a circular clock has 360° total, and there are 12 hours labeled on it evenly, so the angle between each hour label is 360 ÷ 12 = 30.

so, from 3pm to 5pm, it moved by 30° + 30° = 60°.

from 5pm to 5:30, that's only half an hour, so it moved half 30°, or 15°.

60° + 15° = 75°.

Consecutive integers are integers that
gogolik [260]

Answer:   The three numbers are 10, 11, and 12.

10+11+12 = 33

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

Work Shown:

  • x = smallest number
  • x+1 = middle number
  • x+2 = largest number

Each is a positive whole number

Add them up and set the result equal to 33. Solve for x.

(x) + (x+1) + (x+2) = 33

3x+3 = 33

3x+3-3 = 33-3 .... subtract 3 from both sides

3x = 30

3x/3 = 30/3 ..... divide both sides by 3

x = 10

x+1 = 10+1 = 11

x+2 = 10+2 = 12

Note how 10+11+12 = 33 to help confirm our answer.

Drag each number to the correct location on the equations. Each number can be used more than once, but not all numbers will be u
Dmitry_Shevchenko [17]

We are given :

The cost of one adult ticket = a.

The cost of one child ticket = c.

<u>Roy buys</u>

6 adult tickets and 2 child tickets.

Total amount = $66.

Therefore, first equation for Roy total amount would be

<em>6a +2c = 66          --------------------(1)</em>

<u>Elisa buys</u>

5 adult tickets and 4 child tickets.

Total amount = $62.

Therefore, second equation for Elisa total amount would be

<em>5a +4c = 62          --------------------(1).</em>

Therefore,

<h3>Roy <u>6</u>a + <u>2</u>c = <u>66</u></h3><h3>Elisa <u>5</u>a + <u>4</u>c = <u>62.</u></h3>

Annual returns on stock of the Mean Corporation are approximately normally distributed with a mean of 13.9% and standard deviati
maw [93]

Answer:

(a) z=-0.59

(b) Joe will invest in Mean Corporation. The probability of getting an annual return grater than 11% is 72.3%.

Step-by-step explanation:

We have a normal distribution for the annual return of the stock.

This distribution has mean of 13.9% and s.d. of 4.9%.

If X=11%, we can calculate its corresponding z-value as:

z=\frac{X-\mu}{\sigma}= \frac{0.11-0.139}{0.049}= -0.5918

The z-value is z=-0.5918.

The probabilty of P(X>11%)=P(y>-0.5918) is, by the standarized normal distribution table, equal to 0.723.

As its P(y>-0.5918)=P(X>11%)=0.723 bigger than the 70% threshold, Joe will invest in Mean Corporation.
