the answer is C.
A false statement implies a true statement , so the conditional statement is true.
Answer:
260 mph
Step-by-step explanation:
With the information given, we know the plane traveled 650 miles in 2.5 hours
To find the speed, do distance/time
650 ÷ 2.5 = 260
= 260 mph
Let width be “w", length = “l" and perimeter = p
Then l = 3w-4
Perimeter = 2(w+l)
p = 2(w+3w-4) = 2w+6w-8 = 8w-8
Perimeter is 32…
8w-8 = 32
8w = 32+8
8w = 40
w = 5
l = (3×5)-4 = 11
Check… p = 2(5+11) = 2 × 16 = 32
Ans = length is 11
Hope it helps!
Yes it is because you are saving $30 if the trip is $10 each way
Answer:
a. Concentration of nitrogen in water draining from fertilized lands
b. Quantitative
c. Water draining from fertilized lands
Step-by-step explanation:
a. Here we are evaluating the Concentration in miligrams of Nitrogen per liter of water, that drains from fertilized lands.. So thats what is defined as the variable.
b. When we talk about qualitative variblaes, we refer to variables that we can't define with numbers. For example the colour of a car, that's a qualitative variable. In this problem, can put a number on the nitrogen concetration. When we can measure the variable with numbers we consider it to be a quantitative variable. Therefore this is a quantitative variable
c. The implied population is the population where we want to interfer the analysis. In here we want to know the concentration of water draining from fertilized lands. So we are using random samples from a lake, and we extrapolate that analysis to a bigger universe, that it´s the water draining from fertilized lands
