To solve this, you must make use of distance formula, which is defined below:
If we can determine the length and width, we can solve the perimeter. So let's begin! Let's take our first two points, (-1, 4) and (5, 2) and plug the values in.
That's a bit of a mess, so let's simplify. By evaluating(which will take too long to work out on here), we get the square root of 40.
Now for the next set of points: (5, 2) and (4, -1). When we plug them in and evaluate the distance formula, we get the square root of ten.
Now that we have two values, we can simply multiply each by two and add them, because they represent side lengths.
If you plug this entire thing into a calculator, it gives you something like 18.97, which can be rounded up to
19.0 as our answer. So your choice was correct.Hope this is helpful! :)
Answer:
B
Step-by-step explanation:
check using Pythagorean theorem
8^2 = 5^2 + 7^2
64 = 25 + 49
64 = 74
No
Answer:
31.4in
Step-by-step explanation:
The formula is [ C = 2πr ].
C = 2π(5)
C = 10π
C = 10(3.14)
C = 31.4in
Best of Luck!
Answer:
0.64 = 64% probability that they will be awarded the contract for either the Macon Expressway or the Seaview Expressway
Step-by-step explanation:
We solve this question using these events as Venn sets.
I am going to say that:
Event A: Awarded the Macon Expressway.
Event B: Awarded the Seaview Expressway.
Probability that they will be awarded the Macon Expressway contract is 0.65
This means that
The probability that they will be awarded the Seaview Expressway contract is 0.43.
This means that
Furthermore, the probability that they will be awarded both contracts is 0.22.
This means that
What is the
Probability that they will be awarded the contract for either the Macon Expressway or the Seaview Expressway?
Only A:
Only B:
Either
0.43 + 0.21 = 0.64
0.64 = 64% probability that they will be awarded the contract for either the Macon Expressway or the Seaview Expressway
Answer:
it looks hard use a calculator ok :-}
