Answer:
x = -2
Step-by-step explanation:
First, let's solve the inequality:
<span>x - 3 < -9
//add 3 to both sides:
x<-6
the second inequality:
x + 5 ≥ 10</span>
//substract 5 from both sides:
<span>x ≥ 5
So we need to map:
</span>
<span>x<-6
</span><span>x ≥ 5
Now, shading will be to the leftof -6 and to the right of 5 - this is compatible with answers A and B.
A closed circle means that the number is included, so the correct answer is A!</span>
Answer:
The missing volume of gas is 6 liters
Step-by-step explanation:
The following data points represent the volume of gas in each race car driver's tank (in liters):
4,5, 13, ?
Let the missing value be x
Data : 4,5,13,x
28=22+x
28-22=x
6=x
Hence The missing volume of gas is 6 liters
The IQR is the difference between Q3 and Q1.
First we need to get the data from the stem and leaf plot:
10, 23, 23, 28,] [33, 45, 80, 90
Since there are 8 data items Q1 would be the median of the lower half (4 items), both are 23 so Q1 is 23.
Q3 is the median of the upper half, since the middle numbers are not the same we need to average 45 and 80. (45 + 80)/2 = 62.5 so Q3 = 62.5
IQR = 62.5 - 23 = 39.5
