Answer:
292.72 ft (Assuming it is to scale)
Step-by-step explanation:
Side a = 26
Side b = 26
Side c = 26
Angle ∠A = 60° = 1.0472 rad = π/3
Angle ∠B = 60° = 1.0472 rad = π/3
Angle ∠C = 60° = 1.0472 rad = π/3
C=60°B=60°A=60°b=26a=26c=26
Area = 292.71659
Perimeter p = 78
Semiperimeter s = 39
The x axis of the graph show the distance driven and y axis represnt Gas remains
at 40 miles of distance i.e x =40
Then value of y at x = 40 is 3.5 i.e. y = 3.5
Answer:
If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be 3.6% or less?
Step-by-step explanation:
First of all, when you want to contrast two hypothesis you need a confidence level p% without which the comparison makes no sense.
In this case, you want to refuse the null hypothesis (the average is 5%) with an alternative one (the average is less than 5%).
You propose a new average (3.6%) based on the evidence.
You cannot prove that the average is actually 3.6%, <em>but if you somehow determine that the probability the average is greater than 3.6% is lower than 100% minus your confidence level p% ,then you can refute the null hypothesis and accept the alternative one as new average.
</em>
So, from the possible choices, the one that fits the best is
If we examine a sample of tires used for 60,000 miles and determine the proportion that are worn out, how likely is that proportion to be 3.6% or less?
I've never done this b4, but i'm pretty sure u just multiply all those numbers together!
Answer:
D. X=7
Step-by-step explanation:
Use the order of operations to solve this problem.
First, combine like terms.
7x-5x=2x
Our equation is now 2x-3=x+4
Now, add 3 to both sides.
Our equation is now 2x=x+7
Subtract x from both sides.
x=7
The answer is D. X=7
