Sherri rolls a dice, numbered 1 to 6, 64 times. How many times can she expect to roll an odd number?
gregori [183]

Answer:

32

Step-by-step explanation:

Possible outcomes in a fair sided die 1,2,3,4,5,6 = 6 possible outcomes

Odd numbers = 1,3,5 = 3 odd numbers

Probability of rolling an odd number = \frac{3}{6} = \frac{1}{2}

Total number of rolls = 64

expected number of odd number rolls in 64 roll,

= \frac{1}{2} x 64 = 32

a machine made 2 2/6 pencils in 3 3/4 minutes. how many pencils would the machine have made after/minute
erma4kov [3.2K]

<em><u>Question:</u></em>

A machine made 2 2/6 pencils in 3 3/4 minutes. How many pencils would the machine have made after 9 minutes?

<em><u>Answer:</u></em>

\frac{504}{90}\ or\ 5.6 pencils is made after 9 minutes

<em><u>Solution:</u></em>

Given that,

A machine made 2 2/6 pencils in 3 3/4 minutes

Which means,

2\frac{2}{6} = \frac{14}{6}

3\frac{3}{4} = \frac{15}{4}

Let "x" be the number of pencils made in 9 minutes

Therefore,

\frac{14}{6}\ pencils = \frac{15}{4}\ minutes\\\\x\ pencil = 9\ minutes

This forms a proportion and we can solve by cross multiplying

\frac{14}{6} \times 9 = \frac{15}{4} \times x\\\\x = \frac{14}{6} \times 9 \times \frac{4}{15}\\\\x = \frac{504}{90}\\\\x = 5.6

Thus, \frac{504}{90}\ or\ 5.6 pencils is made after 9 minutes

Mr. Rodriguez asked 60 randomly chosen students from each grade level at Willowbrook School about their favorite types of readin
Pepsi [2]

Answer: Yes, he makes a reasonable inference.

Step-by-step explanation:

Since we have given that

Number of students = 60

Number of chosen science students = 12

Percentage of students who chose science is given by

\frac{12}{60}\times 100\\\\=\frac{1}{5}\times 100\\\\=20\%

Since Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction.

So, he makes a reasonable inference.

at the beginning of the basketball game Sabrina made nine points in four minutes she wants to break the school record of 119 poi
svetlana [45]
Yes she will break the school record if she continues to score at that rate. You divide 60 / 4 since there are 60 minutes in a full game. That gives you 15. Then you multiply that answer by 9 because she scores 9 points each of those 4 minutes. That will get her to score 135 points by the end of the game
