Answer:

hey we can only see 13 and for 13 is<em><u> X = 57.36</u></em>

Step-by-step explanation:

since we have opposite and the hypotenuse we use sin...

sin(theta) = opp/hyp

sin(38) = 17/x

and we multiple x to both sides which leaves us with

x * sin(38) = 17

and then divide sin(38) so x can be by it- self which gives us

x = 17/sin(38

X = 57.36

astra-53 [7]

Answer:

The value of the standard error for the point estimate is of 0.0392.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes 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.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

In a randomly selected sample of 100 students at a University, 81 of them had access to a computer at home.

This means that n = 100, p = \frac{81}{100} = 0.81

Give the value of the standard error for the point estimate.

This is s. So

s = \sqrt{\frac{0.81*0.19}{100}} = 0.0392

The value of the standard error for the point estimate is of 0.0392.

Solve the following <br> 2(x-2)=8
Talja [164]

Answer:

2

Step-by-step explanation:

2 (x-2)=8 equal to 2x-4=8, put -4 to the other side by subtracting 4 on both sides once you do you get 2x=4 so 4 divided by 2 equals 2.

The double number line shows that Toni can type 180180180 words in 222 minutes. Based on the ratio shown in the double number li
vfiekz [6]

Answer:

<h3>Toni can type words in 3 minutes is 270 words</h3>

Step-by-step explanation:

Given that the double number line shows that Toni can type 180 words in 2 minutes.

<h3>To find how many words can Toni type in 3 minutes:</h3>

From the given Toni can type 180 words in 2 minutes,

⇒ Toni can type \frac{180}{2}

= 90

<h3>∴ 90 words per minute </h3>

For Toni would be able to type words in 3 minutes is

90\times 3

= 270

<h3>∴ 270 words per minute.</h3><h3>∴ Toni can type words in 3 minutes is 270 words.</h3>
