Which expression can be used to find the length of AT?
irina [24]

Answer:

      \large\boxed{\large\boxed{\overline{AT}=12.5(cos66\º)}}

Explanation:

In a right triangle the angle between the hypotenuse and the adjacent leg to the angle are related by the trigonometric ratio cosine.

Cosine is the ratio of the adjacent leg to the hypotenuse:

In the right triangle ART, AT is the hypotenuse,  AR is the ajacent leg to the angle 66º, and RT is the opposite leg to the angle 66º.

Then, the length of AT and 12.5 is related by the cosine ratio:

       cos(66\º)=\dfrac{\overline{AT}}{12.5}

Multiplying both sides of the equation by 12.5in:

            \overline{AT}=12.5(cos66\º)     ← answer

Will mark as brainliest plz help <br>The value of (17+ V2)(17– V2) is<br>​
MAXImum [283]

Using formula a^2- b^2 = (a-b)(a+b)

(17 + v ^{2} )(17 -  {v}^{2} ) \\  = (17)^{2}  -  {(v ^{2} )}^{2} \\  = 289 -  {v}^{4}

Question 15
larisa86 [58]

Answer:

The correct option is (C).

Step-by-step explanation:

According to the Central Limit Theorem if we have n unknown population with mean <em>μ</em> and standard deviation <em>σ</em> and appropriately huge random samples (<em>n</em> > 30) are selected from the population with replacement, then the distribution of the sample means will be approximately normally distributed.

Then, the mean of the distribution of sample means is given by,

\mu_{\bar x}=\mu

And the standard deviation of the distribution of sample means is given by,

\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}

The information provided is:

<em>μ</em> = 3.5

<em>σ</em> = 1.7078

<em>n</em> = 400 = number of times the experiment is repeated.

As the sample size is quite large, i.e. <em>n</em> = 400 > 30 the central limit theorem can be used to approximate the sampling distribution of the sample mean.

The mean of the distribution of sample means is:

\mu_{\bar x}=\mu=3.5

The standard deviation of the distribution of sample mean is:

\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}=\frac{1.7078}{\sqrt{400}}=0.0854

The distribution of the sample mean is:

\bar X\sim N(\mu = 3.5,\ \sigma=0.0854).

Thus, the correct option is (C).

The parallelogram shown below has an area of 30 units2.
Sauron [17]

Answer:

I think its 6 units

Step-by-step explanation:

The area is 30 units so therefore you would divide it by any side so therefore if you would do 30 divided by 5 you would get 6.
