Answer:
3) ½ chance
4) 60 times
Step-by-step explanation:
<h3><u><em>
3) Theoretically, if the spinner is spun 150 times</em></u></h3><h3><u><em>
how many times would you expect to get an</em></u></h3><h3><u><em>
even number?</em></u></h3>
<u><em></em></u>
There are 12 equal sections, getting an even numbers is a ½ chance. ( same as odd numbers)
The probability is ⁶⁄₁₂ or ½.
In addition, this is theoretical probabilty, it doesn't require experiments.

4) Based on the experiment, if the spinner is</em></u></h3><h3><u><em>
spun 150 times, how many times would you</em></u></h3><h3><u><em>
expect to get an even number?</em></u></h3>
Getting a 2: ⁴⁄₆₀ or ¹⁄₁₅
Getting a 4: ³⁄₆₀ or ¹⁄₂₀
Getting a 6: ⁷⁄₆₀
Getting a 8: ³⁄₆₀ or ¹⁄₂₀
Getting a 10: ⁵⁄₆₀ or ¹⁄₁₂
Getting a 12: ²⁄₆₀ or ¹⁄₃₀
Chance of picking a even number using 60 tries:
⁴⁄₆₀ + ³⁄₆₀ + ⁷⁄₆₀ + ³⁄₆₀ + ⁵⁄₆₀ + ²⁄₆₀ = ⁴ ⁺ ³ ⁺ ⁷ ⁺ ³ ⁺ ⁵ ⁺ ²⁄₆₀ = ²⁴⁄₆₀ or ⅖
Picking a even number using 150 tries:
⅖ · 150 = 60 times
Answer:
three-fifths over three-eights equals one and three-fifths miles per hour
Step-by-step explanation:
- The martinez family walked three over five of a mile; this means they walked 3/5 of a mile.
- They walked such distance in in three over eight of an hour, this means 3/8 of an hour.
To find the rate in miles per hour, we have to divide 3/5 divided 3/8.
TO make division of fraction, we must invert the second fraction and multiply them:
The ratio is 8/5 miles per hour. In the answer given it is expressed as a mixed numer 1 3/5 that is equal to 8/5.
To transform a fraction to a mixed number, you have to divide numerator by denominator. Explanation is in figure attached.
the circumference will double
Answer:
See diagram below. This is a relation and not a function.
Step-by-step explanation:
An arrow diagram has two ovals - one for x -values and one for y-values. Inside the ovals, all values ONLY appear ONCE and generally from least to greatest. Then draw an arrow from each value to its matching value from input to output according to the table.
Be sure to draw two ovals around the lists below:
Inputs Outputs
1 ----------------> 2
11 -----------------> (POINTS DIAGONAL TO 2)
15 -----------------> 12
16 ------------------> 32
This is not a function because each output must only match to one input. The output 2 matches to both 1 and 11. This is a relation.
the answer is simple and easy. why do you ask such question.
anyway answer is D i.e. 6l²(6*7*7)
