6.2 x 10^-3 Because when you add them together you get .0062 so you don't want anymore than one number to the left of decimal when in scientific notation therefore its 6.2 so you wanna move the decimal three spaces to the left to get .0062 therefore its 6.2x10^-3

When the number of degrees of freedom is large, the student's distribution is close to the?
lutik1710 [3]

The number of degrees of freedom is large, then the student's T distribution is close to the normal distribution.

The degrees of freedom is the number of observation in a sample that are free to vary when we estimate the statistical data. Degree of freedom will also indicate the independent piece of information in the data.

Basically, the T distribution or student's distribution is a family's of distribution that look identical to the normal distribution.

So, the number of degrees of the freedom is large then it will closely related to normal distribution.

To know more about degrees of freedom here.

The city planning committee wants one tree planted every 20 ft along Dayton Ave. if the perimeter of the plot of land is 234 ft
Vladimir [108]

Answer:

2 trees

Step-by-step explanation:

Since the city is planting a tree every 20 feet across Dayton Avenue, then we need to find the length of the side that is on Dayton Avenue.

We are missing 3 sides to this. But it's extremely important to note that the side adjacent to Dayton Avenue is the same length as the other missing two sides combined. This is because both of these lengths contain the 1 feather and 2 feather mark - these signify congruence.

This means that the side lengths of both of them combined will be 234-52-68=114

This means the side adjacent to Dayton Avenue is

114\div2=57 feet long.

Now that we know that the side is 57 feet long, we have to divide this by 20, as a tree is being placed every 20 feet. If we get a decimal, we will have to round down because it gets planted only, and only if, 20 more feet has been accomplished. If we are a fraction of the way there, a tree doesn't get planted.

57\div20=2.85

Rounding down gets us 2.

Hope this helped!

A lottery game requires that a person select in uppercase or lowercase letter followed by two different two-digit numbers (where
Irina-Kira [14]

Using the Fundamental Counting Theorem, it is found that there are 416,520 ways to fill out a lottery ticket.

<h3>What is the Fundamental Counting Theorem?</h3>

It is a theorem that states that if there are n things, each with n_1, n_2, \cdots, n_n ways to be done, each thing independent of the other, the number of ways they can be done is:

N = n_1 \times n_2 \times \cdots \times n_n

In this problem:

  • First, one uppercase or lowercase letter is chosen, there are 26 of each, hence n_1 = 52.
  • Then, two different two-digit numbers are chosen, and there are 90 of them, hence n_2 = 90, n_3 = 89, as the third digit has to be different of the second.

Then:

N = n_1n_2n_3 = 52(90)(89) = 416520

There are 416,520 ways to fill out a lottery ticket.
