Answer:
The probability is 0.33696
Step-by-step explanation:
The probability that the outcome will be heads x times is calculated using the following equation:
nCx is calculated as:
This apply for variables that follows a binomial distribution. In which we have n independent and identical events with two possibles results: success and fail with a probability p and 1-p respectively.
So, In this case, n is equal to 5, and p is equal to 0.6 because we are going to call success the event in which the outcome of the coin is head.
Then, the probability that the outcome will be heads at least 4 times is calculated as:
P = P(4) + P(5)
Where P(4) is:
P(4)=0.2592
And P(5) is:
P(4)=0.07776
Finally, the probability is:
P = 0.2592 + 0.07776
P = 0.33696
Answer:
Parallel
Step-by-step explanation:
In the slope-intercept form (y=mx +c), the coefficient of x tells us the slope of the line.
2x +8y= 56
Let's rewrite this equation into the slope-intercept form.
8y= -2x +56
Dividing both sides by 8:
Slope= -¼
y= -¼x -5
Slope= -¼
Since both lines have the same slope, they are parallel to each other.
Ok i hope this helps and if it does pls give me brainliest!
So the longest line is 8 and makes a 90 degree angle with another smaller line which is labled 3.6. X is longer than 3.6 ( only by a little bit) But it looks like its half of the longest line (8). So i think the answer would be X equals 4. But i was thinking about it more i relized that you would prob just divide 8 by 3.6 which would be 2.22222 .... And that rounded tot he nearest 10th would be 2.2.
I know step 5 is (x-2)(x+2)(x+1)
But I don't know what step 4 is.
Im stuck.
Hello there!
The first thing you must do is to find the slope of the line. To do this, find the negative reciprocal of your current equation. Since your current slope is 3, the negative reciprocal of that would be -1/3, which would be your slope.
Now that you have your slope, plug it into the slope intercept equation as well as your known points:
(1,8) m(slope)=-1/3
8=1(-1/3)+b
Now, solve for b:
8=1(-1/3)+b
8=-1/3+b
b=25/3
Now that you have the slope and the b value, you can conclude that your equation would be:
y=-1/3x+25/3
