ANSWER: The distance between X (-3, -4) and Y (5, 5) is: 12.041594578792, or in a simpler version: 12
In order to find the value of x, you have to cross multiply both equations. 4x-10 is basically 4 times something subtract 10. Same thing as well for 3x-2. Now it says to find the value of x. X has to also be the same answer for both equation as well. By the way x doesn't have a given number so there is no specific answer.
Answer:
0.0433
Step-by-step explanation:
Since we have a fixed number of trials (N = 25) and the probability of getting heads is always p = 0.05, we are going to treat this as a binomial distribution.
Using a binomial probability calculator, we find that the probability of obtaining heads from 8 to 17 times is 0.9567 given that the con is fair. The probability of obtaining any other value given that the coin is fair is going to be:
1 - 0.9567 = 0.0433
Since we are going to conclude that the coin is baised if either x<8 or x>17, the probability of judging the coin to be baised when it is actually fair is 4.33%
Answer:
10t
Step-by-step explanation:
The 1st thing we can do is take out the paranthesis so now we have 7t+3t. We can add 7 and 3 and noow we get 10 so the answer is 10t
Answer:
y = -2x+8
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4-4)/(6-2)
= -8/4
= -2
The slope is -2
We can use the slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -2x +b
Using the point ( 2,4)
4 = -2(2) +b
4 = -4+b
Add 4 to each side
4+4 = -4+4+b
8 = b
y = -2x+8
