Which list shows the triangles in order from greatest area to least area

Mathematics
1 answer:
aleksandr82 [10.1K]3 years ago
7 0

Answer:

H - Triangle Z, Triangle X, Triangle Y

Step-by-step explanation:

Triangle X area = rad(66.5) cm^3 ≈ 8.155cm^3

Triangle Y area = 8.15cm^3

Triangle Z area = (17.5/2)cm^3 = 8.75cm^3

8.75cm^3 > 8.155cm^3 > 8.15cm^3

Therefore:

Triangle Z area > Triangle X area > Triangle Y area

What is the following product ?
AfilCa [17]

Answer:

The correct answer is option B). 7x² -12x√14 + 72

Step-by-step explanation:

I<u>dentity</u>

(a - b)² = a² - 2ab + b²

Find the product

It is given that ( x√7 - 3√8)(x√7 - 3√8)

(x√7 - 3√8)(x√7 - 3√8) =  (x√7 - 3√8)²

(x√7 - 3√8)² =  (x√7)² - 2*x√7*3√8 +(3√8)²

 = 7x² - 6x√56 + 72

 = 7x² - 6x*2√14 + 72

 = 7x² - 12x√14 + 72

Therefore the correct answer is option B).  7x² - 12x√14 + 72

A forester studying the effects of fertilization on certain pine forests in the Southeast is interested in estimating the averag
ahrayia [7]

Answer:

P(-2 \leq \bar X -\mu \leq 2)

If we divide both sides by \frac{\sigma}{\sqrt{n}} we got:

P(\frac{-2}{\frac{4}{\sqrt{9}}}\leq Z \leq \frac{2}{\frac{4}{\sqrt{9}}})

And we can use the normal distribution table or excel to find the probabilites and we got:

P(-1.5 \leq Z \leq 1.5)= P(ZStep-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the area of a population, and for this case we know the distribution for X is given by:

X \sim N(M,4)  

Where \mu=M and \sigma=4

We select a a sample of n =4 and since the distribution for X is normal then we know that the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

And we want to find this probability:

P(-2 \leq \bar X -\mu \leq 2)

If we divide both sides by \frac{\sigma}{\sqrt{n}} we got:

P(\frac{-2}{\frac{4}{\sqrt{9}}}\leq Z \leq \frac{2}{\frac{4}{\sqrt{9}}})

And we can use the normal distribution table or excel to find the probabilites and we got:

P(-1.5 \leq Z \leq 1.5)= P(Z

A box of pancake mix has `6` cups of mix.
kenny6666 [7]

The fraction of the box of pancake that eliza used is; 1/8.

<h3>What are fractions?</h3>

We are told that the box of pancake mix has 6 cups.

Now, Eliza uses 3/4 of a cup for a recipe.

Since there are 6 cups in the box, it means the fraction of the box of pancake that Eliza used is;

(3/4)/6 = 3/24 = 1/8

In conclusion, the fraction of the box of pancake that eliza used is 1/8.
