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:

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

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

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

Chance wants to wish his cousin a happy birthday at 9:00am CST. Chance lives in Texas and his cousin lives in Ohio. What time wi

Neporo4naja [7]

Answer:

10:00 am EST in Ohio

Step-by-step explanation:

Using the 50 States Time zones attached in the image below.

Chance who lives in Texas has a Time zone of CST (central standard time), while his cousin who lives in Ohio has a Time zone of EST(eastern standard time).

So if it is 5 pm in CST, it will be 6 pm in EST.

Given that;

Chance wants to wish his cousin in Ohio at 9:00 am CST, then the time it will be at his cousin's house when Chance calls to say happy birthday will be:

9:00 am + 1 = 10 :00 am EST in Ohio

2. What is the equation of the line that passes through the point (-4,-7) and is

Dima020 [189]

Answer:

2x+1=y

Step-by-step explanation:

Parallel means has the same slope, so slope equals 2

2x+b=y (we don't know the y-intercept)

plug in x and y

2(-4)+b=-7

-8+b=-7

b=1

so, 2x+1=y
