Answer:

The correct answer will be option-A

Explanation:

The key components of an investigation are the experiments and the results.

In the given question, since the study was conducted over 76 people for 10 years out of which data of only 68 people were collected after 10 years.

This will lead to disturb the analytical part of the results as the data of 8 experimental samples is missing. Therefore the hypothesis of the experiment would not be tested.

1. Ruth Lockwood earns $2,917 a month as a supervisor for Acme
soldi70 [24.7K]

Answer:

a. 25%

b. $1560

c. $130

Step-by-step explanation:

a.

If 75% is paid by company, the rest is paid by Ruth.

Out of 100%, 75% is paid by company, so Ruth pays 100 - 75 = 25%

b.

Per year, the total amount paid is 6240, but Ruth pas 25% of this. So,

25% = 0.25

To get the answer, we multiply 0.25 with 6240.

0.25 * 6240 = 1560

So, $1560 is paid by Ruth annually.

c.

Since 1560 is paid annually (in 12 months), each month Ruth has to pay:

1560/12 = $130

Hence, $130 is deducted each month from her paycheck

The hour hand of a clock is 6 inches long and the minute hand is 8 inches long. What is the ratio of the distance in inches trav
kirill115 [55]

Answer:

the ratio of the distance in inches travelled by the tip of the hour hand to the distance in inches travelled by the tip of the minute hand is <em>0.125</em>.

Step-by-step explanation:

The given information is:

  • length of the hour hand, l = 6 inches
  • length of the minute hand, b = 8 inches

Therefore, since the tip of the minute moves from 12 to 3, it moved a distance of:

s₁ = r θ

s₁ = (8)(π/2)

s₁ = 4π inches                                                                      

The hour hand moves 30 degrees / 60 = 1/2 degree in a minute.

Therefore, in 30 minutes the hour hand moves a distance of:

s₂ = r θ

s₂ = 6(30×1/2×π/180)

s₂ = π/2 inches                                                                              

Therefore, the ratio of the distance in inches travelled by the tip of the hour hand to the distance in inches travelled by the tip of the minute hand is:

s₂ / s₁ = (π/2) / 4π

<em>s₂ / s₁ = 0.125</em>
