Of the 80 boys polled at lunch, 55% say they play video games daily. According to the poll, how many boys play video games daily

alexdok [17]

$55% = \frac{55}{100} = \frac{11}{20}$

Multiply $\frac{11}{20}$ by 80 and you will get how many boys play video games daily.

$\frac{11}{20}*80=\frac{11}{1}*4=11*4=44$

44 is the number of boys who play video games daily.

An administrator surveys a random sample of 48 out of 900 middle school

Verizon [17]

Considering the definition of probability, 12 of the 48 students surveyed were in favor of the new dress code.

<h3>Definition of probability</h3>

Probability is the greater or lesser chance that a given event will occur.

In other words, the probability establishes a relationship between the number of favorable events and the total number of possible events.

Then, the probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.

P(A)=number of favorable events÷ number of total events

<h3>Probability that students are in favor of the new dress code</h3>

In this case, you know:

Total number of middle school students = 900 (number of possible cases)
The number of students are in favor of the new dress code = 225 (number of favorable cases)

Replacing in the definition of probability:

P(A)=225 students÷ 900 students

Solving:

<u><em>P(A)= 0.25</em></u>

Expressed as a percentage:

<u><em>P(A)= 25%</em></u>

<h3>Number of the 48 students surveyed were that in favor of the new dress code</h3>

In this case, you know:

Total number of middle school students = 48 (number of possible cases)
25% students are in favor of the new dress code (P(A)= 25%= 0.25)

Replacing in the definition of probability:

0.25=students in favor of the new dress code÷ 48 students

Solving:

students in favor of the new dress code= 0.25×48 students

<u><em>students in favor of the new dress code= 12 students</em></u>

Finally, 12 of the 48 students surveyed were in favor of the new dress code.

Jennifer buys 4.25 pounds of gummy worms for $2.96 per pound and 0.5 pounds of jaw

GuDViN [60]

Answer:

$4.94

Step-by-step explanation:

Gummy worms cost $2.96 per lb, and she bought 4.25 lbs, so:

2.96 * 4.25 = $12.58 spent in gummy worms

Jaw breakers cost $4.95 per lb, and she bought 0.5 lbs, so:

4.95 * 0.5 = $2.48 spent in jaw breakers

Adding the gummy worms and the jaw breakers, she spent:

12.58 + 2.48 = 15.06 in Total

She gave the clerk $20.00, but she only spent only $15.06, so the clerk gave her back the difference:

20 - 15.06 = $4.94 is the change that she received

The sum of four consecutive integers is 266. What are the integers?

algol13

Answer:

The 4 consecutive integers are 65,66,67,68

Step-by-step explanation:

Ok so there are 4 different numbers and they are consecutive, so you'd start of like:

266= n+(n+1)+(n+2)+(n+3). Next you would collect like terms to simplify..

266=4n+6. Next you want to solve for n...

266-6=4n+6-6

260=4n

260/4=4n/4

65=n....so you have n.hurray, but you need the other three numbers..so just substitute 65 as n in the formula:

266=65+(65+1)+(65+2)+(65+3)

266=65+66+67+68

266=266 both sides are equal so it means the equation is solved. The 4 consecutive integers are 65,66,67,68
