Step-by-step explanation:

The significance level, also denoted as alpha or α, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference

On a coordinate plane, a parabola opens up and goes through (-6.5, 0), has a vertex at (-2, -10), and goes through (2.5, 0).

The correct option is B.

What is parabola?

A plane curve produced by a moving point such that its separation from a fixed point equals that of a fixed line is a parabola.

Given:

A function,

y = x²/2 + 2x - 8

The graph of the function is given in the attached image.

The vertex of the parabola is (-2, -10).

On a coordinate plane,

a parabola opens up and goes through (-6.5, 0), has a vertex at (-2, -10), and goes through (2.5, 0).

Therefore, a parabola opens up and goes through (-6.5, 0), has a vertex at (-2, -10), and goes through (2.5, 0).

A tank contained 80 liters of water. The function “w” represents the relationship between “t”, time in minutes, and the amount of water in the tank in liters. The equation w(t) = 80 - 2.8t defines this function. How would the graph of the inverse function of compare to the graph of “w”? PLEASE HELP!!

Answers

w(t) tells you the amount of water w at a given time t.

The inverse function tells you at which time t the tank contains an amount of water w.

To get the inverse function, solve the equation

w = 80 - 2.8t

for t :

w = 80 - 2.8t

2.8t = 80 - w

t = (80 - w) / 2.8

t ≈ 28.57 - 0.357 w

The graph of w(t) is a downward-sloping line. The graph of the inverse is also a downward-sloping line, but its intercept (28.57) and slope (-0.357) are both smaller than the intercept and slope of w(t).

Basil and Daniel decided to work at the Carnival for 9 5/6. Basil worked for 4 1/2 hours. How many hours did Daniel work?

Answers

Answer: 5 1/3 hours

Step-by-step explanation:

Since Basil and Daniel decided to work at the Carnival for 9 5/6 hours and Basil worked for 4 1/2 hours, the number of hours that Daniel worked will be gotten by subtracting 4 1/2 hours from 9 5/6 hours. This will be:

= 9 5/6 - 4 1/2

= 9 10/12 - 4 6/12

= 5 4/12

= 5 1/3 hours

Daniel will work for 5 1/3 hours.

You own 100 shares of the stock and it pays $1 per share as dividend.

Amount of dividends you receive will therefore be:

= 100 * 1

Dividends are however, quoted on a yearly basis. The quarterly dividend received would be:
