Answer with explanation:
Data set Showing number of times seventh period class attended a summer camp since first grade:
3, 1, 0, 4, 1,⇒⇒Mean =1.8
4, 2, 3, 0, 5,⇒⇒Mean =2.8
0, 1 , 1, 2, 0,⇒⇒Mean =0.8
4, 1, 4, 4, 2,⇒⇒Mean =3
3, 2, 0, 1, 4⇒⇒Mean =2
⇒≡Mean of a Data set is sum of all the variate in data set divided by total number of Variate in the data set.
Range of the sample Means of a data set is difference between Maximum value of variate in the data set and Minimum value of Variate in Data set.
Maximum Value in the sample mean = 3
Minimum Value in the sample mean = 0.8
⇒Range = Maximum value of mean - Minimum value of mean
= 3 - 0.8
= 2.2
⇒≡None of the option given, matches with the value of range Calculated.
Absolute value of x minus 6 is less than y
one way is to jsut make all the x's positive, then subtract them from 6 and see if they are less
sorry for confusing, just read below
(-5,1)
1>|-5|-6
1>5-6
1>-1
true
(-1,-5)
-5>|-1|-6
-5>1-6
-5>-5
false
(5,-1)
-1>|5|-6
-1>-1
false
answer is (-5,1)
Answers:
21.75
1.37
10
15
Step-by-step:
Dozen flyers:price
4:7.25
12:x
To solve this mulitply 7.25 by 3 (because this is what we multiplied 4 by to get 12) 7.25*3=21.75
Question 2:
We can write teh following equation
.49+.22(x-1)=price
This is essentially saying that we pay .49 for the first ounce and .22 for every ounce after that
We can plug in an x value to get
.49+.22(5-1)
.49+.22(4)
.49+.88
1.37
Question 3:
We can write the following equation
x+2=y
We need to find out what happens when x=8
8+2=10
Question 4:
We can solve this with ratios
x:y
1.5:4.5
5:x
To solve just multiply 4.5 by 10/3 and get 15
We can just multiply
√2 ≈ 1.41
π ≈ 3.14
√7 ≈2.65
√π ≈ 1.77
π² ≈ 9.87
