Phil and his family want to do something fun and memorable on Leap Day. They each come up with an activity: attend a trapeze cla

ss, go fishing, go on a hike, or visit a theme park. They settle on picking the letters L, E, A, and P from a bowl, replacing them after each pick, to make the decision. They repeat this experiment 40 times to verify their model and record the results in this table.
Below is the chart
Activity Letter Times Picked
trapeze class L
10
fishing E
11
hiking A
9
theme park P
10


Based on the results in the table, is this model a fair representation for choosing an activity?
A.
No, it is an unfair model because the outcomes have different frequencies.
B.
No, it is an unfair model because the relative frequency of the letter E is the highest.
C.
Yes, it is a fair model because the relative frequencies of the letters L and P are equal.
D.
Yes, it is a fair model because the relative frequencies of all the outcomes are similar.

The measures of three sides of a triangle can be represented by 2x, 3x and -5, and 4x + 2. The perimeter of the triangle is 65 i
Olenka [21]
The sides are 2x, 3x-5 and 4x+2
perimiter is the sum of the sides

a.
2x+3x-5+4x+2=63 is an equation

b.
solve
group like terms
2x+3x+4x-5+2=65
add like terms
9x-3=65
add 3 to both sides
9x=68
divide both sides by 9
x=68/9


2x=2(68/9)=136/9 in
3x-5=3(68/9)-5=(68/3)-5=(68/3)-(15/3)=53/3
4x+2=4(68/9)+2=272/9+2=272/9+18/2=290/9

the side lengths are 136/9in, 53/3in, and 290/9in

Choose the set of equivalent fractions that correctly uses the LCD for these fractions 3/4 and 1/6
valina [46]

Answer: 9/12, 2/12

Step-by-step explanation:

Start by writing multiples of 6 and 4

4: 4, 8, 12

6: 6, 12, 18

Did you see the multiple that both numbers have? Yup, it's 12. So that has to be your denominator for both fractions. This is because you have to have the <u>LEAST</u> COMMON Denominator (LCD). So both numbers have 12 in common as one of their multiples and, it's the least common one because there are no numbers that come before it that are common for both numbers. Now, you just have to change the denominators of both fractions into 12. To do that to 3/4, just multiply the top and bottom by 3 to get 9/12. To do that to 1/6, just multiply the top and bottom by 2 to get 2/12.  Hope this helps!

NOTE: REMEBER THAT WHATEVER YOU DO TO THE TOP OF A FRACTION, YOU HAVE TO DO IT TO THE BOTTOM TOO (AND VICE VERSA)
