Answer:
y = - x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange - 4x + 4y = 4 into this form by adding 4x to both sides
4y = 4x + 4 ( divide all terms by 4 )
y = x + 1 ← in slope- intercept form
with slope m = 1
given a line with slope m then the slope of a line perpendicular to it is
= - 
= - 
= - 1, thus
y = - x + c ← is the partial equation
To find c substitute (- 4, 5) into the partial equation
5 = 4 + c ⇒ c = 5 - 4 = 1
y = - x + 1 ← equation of perpendicular line
Answer: a. 1/6. b. 2/3. c. 5/6
Step-by-step explanation:
Number of adults randomly selected= 6
a. Finding the probability of adults that have cheated on an examination before is exactly 4.
The numbers are 1, 2, 3, 4, 5 and 6.
Probability of chosen exactly 4 will be 1/6 since 4 can only occur once.
b. More than 2means 3,4, 5 and 6.
Probability that the number of adults that have cheated on a test or exam is more than 2 will be:
4/6 = 2/3
c. At most 5 means 1,2,3,4 or 5
This will give 5/6
Answer:
Mean of the data would be 6c
Step-by-step explanation:
<u>Rule to Remember:</u> Whenever each term of the data is multiplied by the same number, the new mean is previous mean multiplied by that number.
In this case, original value of mean was c. Each value of the data is multiplied with 6 so a result the new mean would be 6 times the original mean i.e. 6c
Let us consider that original values in the data set are x, y and z. Their mean would be:
If each value of the data is multiplied with 6, the new values would be 6x, 6y and 6z. The mean in this case will be:
We can see from above that the new mean is 6 multiplied to the original mean.
Therefore, the answer to this question is 6c.
