Answer:
20%
Step-by-step explanation:
Cars that are less than 19 mpg : 16, 18
2 cars have less than 19 mpg.
2/10 cars have less than 19 mpg.
To change fraction to percentage :
divide the numerator by the denominator, then multiply the decimal by 100
2/10 = 0.2
0.2*100 = 20
20%
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 2 √ 3 , − 2 √ 3
If the 3 is with the -y, then the 6 is alone and is the constant. Therefore making the the 3 coefficient. However, your choices appear to be -1, 0, 3 or 6; if so, then if the expression is 6 -y *3, then the coefficient would be -1 since it is implied to be in front of the variable y.
D is the answer. To find the apparent zeros, just observe the intersections of the graph with the y axis. On the graph, it's easy to see that when x=-2, 0, and 4, the function intersects the y value (the y value of the function is the zero). The the answer is {-2,0,4}.
Answer:
49.5 units²
Step-by-step explanation:
The applicable formula is ...
Area = 1/2·ab·sin(C) = (1/2)·15·13·sin(30.5°) ≈ 49.48499
≈ 49.5 . . . square units
