forsale [732]

Answer:

They must sell 106 more pizzas to earn $750.

Step-by-step explanation:

We are given that Mrs. Canale class is selling frozen pizzas to earn morning for a field trip. For every pizza sold, the class makes $5.35.

They have already earned $182.90, but they need $750. We have to find that how many more pizzas must they sell to be able to earn $750.

So, Firstly we will find that how much money did they have to earn more to be able to reach at $750.

Since, it is given that they have already earned $182.90.

So, Amount of more money they have to earn to reach at $750 = Final amount - Amount they already have

= $750 - $182.90 = $567.1

<em>That means they have to earn $567.1 more to be able to reach at $750 mark. </em>

Also, it is known that the price of every pizza sold = $5.35

So, Number of pizza that should be sold to earn an amount of $567.1 is given by;

<u>Number of pizzas</u> = $\frac{567.1}{5.35}$ = $\frac{5670}{535}$ = 106

Therefore, Mrs. Canale class must sell 106 more pizzas to be able to earn a total amount of $750.

Several students were asked how many blocks they walk from home to school each day. The results are shown in the line plot. How

serious [3.7K]

Answer:

25 students.

Step-by-step explanation:

A line plot is a simple graph that shows relationship among the values in a data using a number line.

From the line plot, each dot represents a student. While the number on the line shows the number of blocks walk each day by each student.

It can be deduced from the line plot that;

Only 1 student walks through 7 blocks, 2 walk through 5 blocks, 8 walk 4 blocks, 5 walk 3 blocks, 5 walk 2 blocks and 4 walk through 1 block to school each day.

So that;

1 + 2 + 8 + 5 + 5 + 4 = 25

Therefore, the number of students who took part in the survey is 25.

A football team has a probability of .75 of winning when playing any of the other four teams in its conference. If the games are

Alexeev081 [22]

Answer:

0.3164 = 31.64% probability the team wins all its conference games

Step-by-step explanation:

For each conference game, there are only two possible outcomes. Either the team wins it, or they lose. The probability of winning a game is independent of any other game. 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 football team has a probability of .75 of winning when playing any of the other four teams in its conference.

The probability means that $p = 0.75$ , and four games means that $n = 4$

If the games are independent, what is the probability the team wins all its conference games?

This is P(X = 4). So

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

$P(X = 4) = C_{4,4}.(0.75)^{4}.(0.25)^{0} = 0.3164$

0.3164 = 31.64% probability the team wins all its conference games
