Has anybody done Apex 2.2.4 math practice for 8th grade? If so could you send me the answers? I’m totally lost...

At a restaurant a manger recorded the sales for one of his servers named

TiliK225 [7]

Answer: b. Damarias median sale is $52

Step-by-step explanation:

Hi, the correct option is b. Damarias median sale is $52.

If we rank the sales order from lowest to highest

28 46 48 48 52 52 59 60 71 192

Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

Feel free to ask for more if needed or if you did not understand something.

A quiz consists of six multiple choice questions. Each question has four choices. A student who forgot to study guesses randomly

Answer:

0.9945 = 99.45% probability that the student answers at most four questions correctly

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student answers correctly, or he/she does not. The probability of the student answering a question correctly is independent of any other question. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

A quiz consists of six multiple choice questions.

This means that $n = 6$

Each question has four choices. Student guesses randomly.

This means that $p = \frac{1}{4}$

What is the probability that the student answers at most four questions correctly?

This is:

$P(X \leq 4) = 1 - P(X > 4)$

In which

$P(X > 4) = P(X = 5) + P(X = 6)$ . So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 5) = C_{6,5}.(0.25)^{5}.(0.75)^{1} = 0.0053$

$P(X = 6) = C_{6,6}.(0.25)^{6}.(0.75)^{0} = 0.0002$

$P(X > 4) = P(X = 5) + P(X = 6) = 0.0053 + 0.0002 = 0.0055$

$P(X \leq 4) = 1 - P(X > 4) = 1 - 0.0055 = 0.9945$

0.9945 = 99.45% probability that the student answers at most four questions correctly

Which basic geometric figure is labeled with either one capital letter or three capital letters?

tester [92]

Answer-

An angle is labeled with either one capital letter or three capital letters

Solution-

Point-

As a point is 0 dimensional, so you just need 1 point to define a point.

Line-

As a line is 1 dimensional,so you need 2 points to define a line.

Plane-

A plane is 2 0r 3 dimensional, so you need 3 points to define a plane.

Angle-

An angle measures the amount of turn. An angles is labeled with a single letter at the vertex, as long as it is perfectly clear that there is only one angle at this vertex. Otherwise, it is named according to the intersecting lines with 3 letters.
