1. A straight line segment can be drawn joining any two points.

2. Any straight line segment can be extended indefinitely in a straight line.

3. Given any straight line segment, a circle can be drawn having the segment as radius and one endpoint as center.

4. All right angles are congruent.

5. If two lines are drawn which intersect a third in such a way that the sum of the inner angles on one side is less than two right angles, then the two lines inevitably must intersect each other on that side if extended far enough. This postulate is equivalent to what is known as the parallel postulate.

How many invitations should Tyler make each day if his goal is 122 and he already made 66 and he wants to finish in a week

xxMikexx [17]

Tyler should make 8 a day. You do 122-66 which is 56 and there are 7 days in a week so 56 divide by 7 is 8.

Find the area. simplify your answer.

PolarNik [594]

Answer:

The area is:

$2 {x}^{2}$

Step-by-step explanation:

Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.

Therefore:

$a = 2x (x) = 2 {x}^{2}$

Word problem: If 1 yard equals 3 inches, how many inches are in 18 yards?

Mariulka [41]

Answer:

54 inches

Explanation:

From the question, we have that:

1 yard = 3 inches

We are to find the equivalent value of 18 yards in inches. This can be expressed as:

18 yards = x

where x is the unknown value.

Get the value of x by dividing both equations:

$\frac{1}{18}=\frac{3}{x}$

Cross multiply

$\begin{gathered} 1\times x=3\times18 \\ \\ x=54 \end{gathered}$

This shows that there are 54 inches in 18 yards

For a population with an unknown distribution, the form of the sampling distribution of the sample mean is _____.a. exactly norm

maxonik [38]

Answer:

Approximately normal for large sample sizes

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this question:

The distribution is unknown, so the sampling distribution will only be approximately normal when n is at least 30.

So the correct answer should be:

Approximately normal for large sample sizes

Step by step helpp.!!

krok68 [10]

Answer:

0.009 or nine thousandth s
0.01 or one hundredths
0.8 or eight tenths

Step-by-step explanation:

first you look for the place example the first question 46.339 it's place is 9 as u start from right is not the way you start from the left side left u start with ones but right you start with tenths so 3 is tenths the other 3 is is hundredths thus making 9 thousandths.Making the values 0.009 or nine thousandths.
Then next is 142,694.11 is rather much simple than the other one so it goes like this place of the first 1is tenths the other 1is hundredths now about the value the first number on the left make it be a zero so as to get the value much easier so this one would be 0.01 because the second 1was hundredths
The last one 5,607.8 place value is tenths because as I started by teaching u that the first right no. is tenths . so the value would be 0.8 or eight tenths, thank you for ask, ask and ask because well are glad to answer have a great life.
