The normal distribution is:
A. a distribution that can be modeled by a bell-shaped curve, with the
mean, median, and mode all the same value and the proportion for
any range of values defined in a table of normal curve areas (or
probabilities)
B. a bell-shaped density curve defined by the population mean (4),
which determines the position of the center of the curve, and the
population standard deviation (c), which determines the height
and spread of the curve.
C. any distribution that can be modeled by a density curve.
D. a set of values that lie directly on a plot of a bell-shaped density
curve, which is defined by the population mean (x) and the
population standard deviation ().
E. an imaginary histogram in which the width of each class is zero,
and the number of population members is infinite.

What is cosine rule?

In trigonometry, the Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

therefore m² = k²+l²+2klCos M

m² = 4.4²+3.1²+ 2× 3.1×4.4cos 150

m² = 19.36+9.61+27.28(-0.8660)

m² = 28.97-23.62

m² = 5.35

m = √5.35

m = 2.31 cm( nearest tenth)

Therefore the measure of length m is 2.31 cm

Let $f(x) = x^3 + 3x ^2 + 4x - 7$ and $g(x) = -7x^4 + 5x^3 +x^2 - 7$. What is the coefficient of $x^3$ in the sum $f(x) + g(x)$?

Answers

Answer:

6

Step-by-step explanation:

Adding the two polynomials gives

(x^3 + 3x^2 + 4x - 7) + (-7x^4 +5x^3 + x^2 - 7) =

-7x^4 + (x^3 + 5x^3) + (3x^2 + x^2) + 4x + (-7-7) =

- 7x^4 + 6x^3 + 4x^2 + 4x -14

The x^3 term is 6x^3, so the desired coefficient is 6.

Step-by-step explanation:

Well you need to remember the Y reflection rule!

To reflect over the Y axis you must do this:

Take the points in this case

(1,2) and (-2,2)

And you need to use the equation (x,y) --> (-x,y)

So the new points you NEED TO GRAPH ARE

(-1,2) and (2,2)

Hope this helped!

Answer: (-1,2) and (2,2)

Step-by-step explanation:

reflection over the y axis, take the point (x,y) and change the sign of the X-value (-x,y). When You reflect over the y-axis, the y remains the same.

point (1,2) would become (-1,2) reflected over the Y

and (-2,2) would become (2,2)

there is a right angle on the left. A right angle is 90 degrees.

180 - 90 = 90

There is still 90 degrees left, meaning that the right side is a total of 90 degrees.

2x + x = 3x

x = 90/3

x = 30

Therefore,

x = 30 degrees!
