Sunny has a six-sided number cube labeled with the numbers 1 through 6 and a spinner, shown below. What is the probability that
Grace [21]

Answer:

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}

Step-by-step explanation:

Given

Cube = \{1,2,3,4,5,6\}

n(Cube) = 6

Spinner = \{A,B,C,D,E,F,G,H\}

n(Spinner) = 8

See attachment for spinner

Required

P(Cube \ge 5\ and\ Spin[A])

On a number cube, we have:

Cube \ge 5 = \{5,6\} ---- i.e. 2 outcomes

So, the probability is:

P(Cube \ge 5) = \frac{n(Cube \ge 5)}{n(Cube)}

P(Cube \ge 5) = \frac{2}{6}

P(Cube \ge 5) = \frac{1}{3}

On the spinner, we have:

Spin [A] = \{A\} ---- i.e. 1 outcomes

So, the probability is:

P(Spin[A]) = \frac{n(Spin[A])}{n(Spinner)}

P(Spin[A]) = \frac{1}{8}

P(Cube \ge 5\ and\ Spin[A]) is calculated as thus:

P(Cube \ge 5\ and\ Spin[A]) = P(Cube \ge 5) * P(Spin[A])

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{3} * \frac{1}{8}

P(Cube \ge 5\ and\ Spin[A]) = \frac{1}{24}

For the graph x = 1 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your an
Hitman42 [59]
First, x=1 is a vertical line. A line that is perpendicular would be horizontal so it would have a slope of 0. A line parallel to it would be vertical too so it would have and infinite gradient.

A survey was taken asking how many siblings students had.
Rudiy27

Answer:

MEDIAN: 3 IRQ (Interquartile Range): 2

Step-by-step explanation:

To find median, divide the number of data points by 2 (5/2) and round to the nearest whole. So, 5/2 = 2.5 rounded to nearest integer, is 3.

To find the interquartile range, subtract Q1 (1) from Q3 (3) which equals 2.

I hope dis right!!

What is the vertex of the parabola graphed
eimsori [14]

Answer:

Step-by-step explanation:

The vertex is either the highest point on the parabola or the lowest point. We have a positive parabola, so the vertex is a low point. It sits at (2, -4). Locate that point and see what I mean by the lowest point on the parabola.
