Answers

Answer 1

Answer:

Answer:

20 and 90

Step-by-step explanation:

20 + 2(90) = 200

20 + 180 = 200

200 = 200

20 × 2(90)

= 20× 180

= 3,600

For the following normal distribution, give the x-values of the inflection points of the curve (the points where the curve's concavity changes). x ~ N(0, 52)

Answers

Answer:

The x-values of the inflection points of the curve are x = -52 and x = 52.

Step-by-step explanation:

Suppose we have a normal curve with mean $\mu$ and standard deviation $\sigma$

The x-values of the inflection points of the curve are $x = \mu - \sigma$ and $x = \mu + \sigma$

x ~ N(0, 52)

This means that $\mu = 0, \sigma = 52$

$x = 0 - 52 = -52$

$x = 0 + 52 = 52$

The x-values of the inflection points of the curve are x = -52 and x = 52.

Final answer:

The inflection points in a normal distribution occur at one standard deviation above and below the mean. For the distribution x ~ N(0, 52), the inflection points are at -√52 and √52.

Explanation:

In a normal distribution, the inflection points occur at one standard deviation above and below the mean. In the given normal distribution, x ~ N(0, 52), the mean (μ) is 0 and the standard deviation (σ) is the square root of the variance, i.e., √52.

Therefore, the x-values for the inflection points would be μ - σ and μ + σ, which are -√52 and +√52, respectively.

60
50
48

Answers

Answer:

The value of given expression 52 - 4 of (17 - 12) + 4 × 7 = 60

Step-by-step explanation:

Given expression;

52 - 4 of (17 - 12) + 4 × 7

Find:

The value of given expression 52 - 4 of (17 - 12) + 4 × 7

Computation:

52 - 4 of (17 - 12) + 4 × 7

Using BODMAS rule;

52 - 4 of (17 - 12) + 4 × 7

52 - 4(17 - 12) + 4 × 7

52 - 4(5) + 28

52 - 20 + 28

80 - 20

So,

The value of given expression 52 - 4 of (17 - 12) + 4 × 7 = 60
