Answer:
If your question is -2 - 4 - 2 - 2.1 then the answer is -10.1
Step-by-step explanation:
-2 - 4 - 2 - 2.1
= (-2 - 4 ) - 2 - 2.1 Combine -2 with -4 or subtract them
= -6 - 2 - 2.1
= (-6 - 2 )- 2.1 Combine -6 and -2
= -8 -2.1 Combine -8 and -2.1
= -10.1

Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...

The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
Answer:
t≥7
Step-by-step explanation:
11≤t+4
4 moves to the other side hence its sign changes
11-4≤t
7≤t
they change sides
t≥7
the sign was facing t so this does not change
Answer:
The correct answer is: Option D: 26 vehicles
Step-by-step explanation:
Median is the middle value of a sorted data set.
The formula for median depends on the number of values in the dataset.
First of all we have to arrange the given data in order
So,
14 19 23 24 24 24 24 26 26 26 26 26 27 27 28 29 30 30 30 34
Counting the values in the dataset
n = 20
As the number of values is even, the formula for median will be

Putting the values
![M = \frac{1}{2}(\frac{20}{2}th\ value+(\frac{20}{2}+1)th\ value)\\M=\frac{1}{2}(10th\ value +[10+1]th\ value]\\M= \frac{1}{2}(10th\ value + 11th\ value)](https://tex.z-dn.net/?f=M%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B20%7D%7B2%7Dth%5C%20value%2B%28%5Cfrac%7B20%7D%7B2%7D%2B1%29th%5C%20value%29%5C%5CM%3D%5Cfrac%7B1%7D%7B2%7D%2810th%5C%20value%20%2B%5B10%2B1%5Dth%5C%20value%5D%5C%5CM%3D%20%5Cfrac%7B1%7D%7B2%7D%2810th%5C%20value%20%2B%2011th%5C%20value%29)
The 10th value in dataset is 26 and 11th is also 26 so

Hence,
The correct answer is: Option D: 26 vehicles
Answer:
160
Step-by-step explanation:
2² is 4 and the fourth multiple of 10 is 40.
Multiply those numbers together, and you get 160.
