The mean and standard deviation when presenting results?

Mathematics
1 answer:
krek1111 [17]3 years ago
7 0

Answer:

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value. A low standard deviation means that most of the numbers are close to the average. A high standard deviation means that the numbers are more spread out.

Step-by-step explanation:

Write the equation of the line with a slope of 17 and passing through the point (0, 0)
Mkey [24]
The equation for a line is y=mx+b. where m is the slope and b is the y intercept.
The slope of 17 is provided. This means m=17. The point (0,0) tells you the y intercept is 0. This means b=0

Plugging these into the equation and simplifying:
y=17x+0

y=17x

Hope this helps :)

The dictionary is 3 inches thick. What is the volume of the dictionary
Yuki888 [10]

Answer:

Square shaped = 27 cubic inches , Rectangular shaped = 3LW cubic Inches

Step-by-step explanation:

If the dictionary is a square ( all sides are equal ) the the volume is

      V = Length * Length * Length = L^{3}

      V = 3 * 3 * 3 = 27 inch^{3}

while if its rectangular ( all side are not equal ) shaped

      V = Length * Width * Height (thickness)

      V = L * W * 3 = 3LW inch^{3}

A building 50 feet high casts a shadow 68 feet long. Find the measure of the angle of elevation of the sun. Round answer to near
Vedmedyk [2.9K]

Answer:

36 °

Step-by-step explanation:

In this case a rectangular triangle is formed so we can use the trigonometric functions to calculate the angle, they give us the value of the two legs, therefore we can apply the tangent function.

Tan A ° = opposite / adjacent

replacing:

Tan A ° = 50/68

Tan A ° = 0.735

A ° = arc tan (0.735)

A ° = 36.32

Which means that the angle of inclination is 36°
