Answer:
Question 1.
Question 2.
Explanation:
<u>Question 1. Boxed lunch.</u>
<em>The line of the random number table</em> shows these numbers:
There are <em>five different</em> types of <em>fruit</em>: <em>apple, banana, grapes, orange, and peach.</em>
Since there are 10 digits (0 - 9), in order for the random digits represent the event of picking some type of fruits, two different digits are assigned to each type of fruit.
It is stated that the digits <em>2</em> and <u>3</u> are assignated for <em>banana</em>.
Then, to use the random numbers to estimate <em>the probability that a boxed lunch will have a banana</em>, you must count the number of times a 2 or a 3 appears in the <em>line of the random number table</em>. That is why I bolded them.
There are in total 14 digits that are 2 or 3.
How many random numbers were generated: 50.
Hence, the probability is 14/50 = 7/25 = 0.28
<u>Question 2. Spinner</u>
The expected <em>number of times the spinner lands on green</em>, if you spin the spinner <em>90 times</em>, is equal to the probability times the number of times the spinner is spined.
Rise over run would be a thing to start with since you use graphs<span />
Answer: angle B= 54 degrees, a=6, b=8
Step-by-step explanation:
Add the two angles we have to get 126 degrees. Subtract that from 180 degrees to get 54 degrees.
We don't know enough to say which is which for a and b, but we can know that it is 6 and 8 because of pythagorean triples (3,4,5).
Answer:
20
Step-by-step explanation:
Given that: $3.25 in dimes and nickels were distributed among 45 boys.
1 nickel = $0.05
1 dime = $0.10
Let number of coins of dimes be x and the number of coins of nickel be 45-x.
Hence,
0.10x + 0.05(45-x)=3.25
0.10x+2.25-0.05x=3.25
0.05x=3.25-2.25
0.05x=1
x= 1/0.05
x=20
45-x
45-20=25
