Answer:

Step-by-step explanation:

Explanation:-

The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ

So The first statement is not true because symmetrical about the line x = μ not 'm'

Area under normal curve represents the total population

so the total area under the curve is 100 or one so The second statement is true

The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.

95 percentage within two standard deviations
99.7 percentage of the data are within three standard deviations of the mean.
68 percentage of the data are within one standard deviation

All above points are true so In given data the third statement is not true

95 percentage within two standard deviations not one

The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.

All data sets are normally distributed its depend on given data

Left to Right

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point A(1, 4)

Point B(-2, -3)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]: $\displaystyle d = \sqrt{(-2-1)^2+(-3-4)^2}$
(Parenthesis) Subtract: $\displaystyle d = \sqrt{(-3)^2+(-7)^2}$
[√Radical] Exponents: $\displaystyle d = \sqrt{9+49}$
[√Radical] Add: $\displaystyle d = \sqrt{58}$
[√Radical] Evaluate: $d = 7.61577$
Round: $\displaystyle d \approx 7.62$

Answer:

In order of the paragraph:

3, isosceles, greater, 3 in

Step-by-step explanation:

The first drop box has to be 3 because if you add up two sides of a triangle, the sum has to be greater than the third side. If two sides are equal, the triangle is isosceles. The third side cannot be 1 since 1+1 is not greater than 3. So the third side must measure 3in.
