<span>Standard deviation is defined as the quantity which expresses by how much the members of a group is different from the mean value for the group.
</span>
The sample standard deviation with a <span>sample variance of hourly wages 10 will be $3.16.

Explanation:

</span><span>The standard deviation is the square root of the variance.
Therefore,
The square root of 10 dollars can be calculated as:

 </span>√10 = $3.16

A gardener weeds 2/3 of a flower bed in 6 min.
Aleksandr-060686 [28]
So,

To find how much the gardener weeded in one minute, we multiply the fraction by one sixth.

\frac{2}{3} *  \frac{1}{6} =  \frac{2}{18} or  \frac{1}{9}

In decimal form, it would be .11111111111111111111

Leonard purchases a model boat kit for $67.53. He uses a coupon for $25 off a purchase of $50 or more. What is the discounted pr
DerKrebs [107]
Given that the original price of the model boat kit is $67.53 and he has a coupon of $25 off if a purchase is $50 or more. Since the purchase is more than $50, we will deduct 25 from 67.53 so the discounted price of the model boat kit would be $42.53. Hope this answers your question.

Jake tossed a paper cup 50 times and recorded how it landed. the table shows the results:
Darya [45]

The experimental probability of each event is as follows:

  • Landing open side up = 1/50 = 0.02 = 2%.
  • Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.
  • Landing on its side = 44/50 = 0.88 = 88%.

The experimental probability of an event is the ratio of the number of outcomes that favored the event to the total number of outcomes in the experiment.

In the question, we are given that Jake tossed a paper cup 50 times and recorded the position how it landed, which is shown in the table:

Open-sided up: 1

Closed side up 5

On the side: 44.

We are asked to determine the experimental probability of each outcome.

The number of outcomes, when the landing is open-sided up is 1.

The number of outcomes, when the landing is closed-sided up is 5.

The number of outcomes, when the landing is on the side up is 44.

The total number of times the experiment took place is 50.

Thus, the experimental probability of each event is as follows:

  • Landing open side up = 1/50 = 0.02 = 2%.
  • Landing closed side up = 5/50 = 1/10 = 0.1 = 10%.
  • Landing on its side = 44/50 = 0.88 = 88%.

Greg spent 3/4 of an hour each day for 2 days working on his project.Giselle spent 1/4 of an hour each day for 6 days working on
DerKrebs [107]

Answer:

C)They spent the same amount of time.

Step-by-step explanation:

Greg did 3/4 of an hour is 45mins for 2 days is x2 so Greg in total did 1 and 1/2 hours

Giselle did 1/4 of an hour which is 15mins for 6 days so x6 so Giselle did 1 and 1/2 hours too.

C)They spent the same amount of time on the project
