Answer: x = 38°

Steps:
The little square in the corner tells us that the angle is 90°
x + 52 = 90
x = 90 - 52
x = 38°

Check:
x + 52 = 90
52 + 38 = 90
90 = 90 ✅

If this was helpful and correct I would appreciate the brainliest! :)

Which of the following is the domain and range of the ellipse with equation 4x2 + 25y2 – 8x + 100y + 4 = 0?
Likurg_2 [28]

The domain of the ellipse is [-4. 6] and the range of the ellipse is [-4. 0]

<h3>How to determine the domain and the range of the ellipse?</h3>

The equation of the ellipse is given as:

4x^2 + 25y^2 – 8x + 100y + 4 = 0

Next, we plot the graph of the ellipse

See attachment for the graph of the ellipse

<u>The domain</u>

From the attached graph the minimum and the maximum values of x are:

Minimum = -4

Maximum = 6

So, the domain of the ellipse is [-4. 6]

<u>The range</u>

From the attached graph the minimum and the maximum values of y are:

Minimum = -4

Maximum = 0

So, the range of the ellipse is [-4. 0]

Hence the domain of the ellipse is [-4. 6] and the range of the ellipse is [-4. 0]

The proportion of items in a population that possess a specific attribute is known to be 0.40. If a simple random sample of size
WARRIOR [948]

Answer:

The sampling error =  0.06

Step-by-step explanation:

From the given information:

Let represent \beta to  be the population proportion = 0.4

The sample proportion be P = 0.46   &

The sample size be n = 100

The population standard duration can be expressed by the relation:

Population standard duration \sigma = \sqrt{\dfrac{\beta(1- \beta)}{n}}

\sigma = \sqrt{\dfrac{0.4(1-0.4)}{100}}

\sigma = \sqrt{\dfrac{0.4(0.6)}{100}}

\sigma = 0.049

The sample proportion = 0.46

Then the sampling error  = P - \beta

The sampling error  = 0.46 - 0.4

The sampling error =  0.06
