Answer:
x = 15
Step-by-step explanation:
you have a straight line and a straight line measures 180. You have a 90 degree symbol.
180 = 90 + 47 + 2x + 13
180 = 150 + 2x Subtract 150 from both sides of the equation
30 = 2x Divide both sides by 2
15 = x
#1: The whole value of data is 21.
There are 21 data values on the dot plot.
#2: The number of data values is 14.
#3: The unit is: 21 ÷ 14.
And it is 1.5.
#4: A statistical question can be answered by collecting data and where there will be variability in that data.
For example, how many students enjoy playing game?
Answer:
The required expression is s = m + n
Step-by-step explanation:
Let m be the number of index cards stuffed in the envelopes and n be the number of extra index cards.
Let s be the total number of index cards.
Then, s = m + n represents the number of index cards the boys started with.
For Marty,
He has 15 stuffed envelopes and 4 extra index cards.
So, m = 15, n = 4
Therefore, s = 15 + 4 = 19
Marty started with 19 cards.
For Stewart,
He has 12 stuffed envelopes and 6 extra index cards.
So, m = 12, n = 6
Therefore, s = 12 + 6 = 18
Steward started with 18 cards.
Answer:
The answer should be 5:12.
Step-by-step explanation:
Since the question asks what's the ratio of cheerleaders to football players, the ratio before simplifying would be 20:48.
So, just find the greatest common divisor of 20 and 48, which would be 4.
20/4 = 5
48/4 = 12
Therefore, the answer to this question and the ratio of cheerleaders to football players is 5:12.
First, add 2x on both sides. then add 29 on both sides. you want to remove the negatives when you're doing this. now you have 7x equals 56. now you divide 7 on both sides. you want to do this because your isolating the variable. now to get x equals 8.
