Answer: It would not be unusual to randomly select 11 people and find that greater than 9 recognize the famous brand name.
Step-by-step explanation:
Since we have given that
Mean = 6.2
Standard deviation = 0.51
Average number of people = 11
So, using the normal distribution, we get that
Now, we will check that
Hence, It would not be unusual to randomly select 11 people and find that greater than 9 recognize the famous brand name.
Answer:
C. x = -12 and x = 2
Step-by-step explanation:
-x²-10x+24=0 Original equation
x²+10x-24=0 Divide everything by -1
(x+12)(x-2)=0 Factor it out
x=-12,2 Solve so that the inside of the parentheses equals 0
Answer:
function b
Step-by-step explanation:
When its asking for which function has a greater rate of change its asking for which slope has a greater value
the slope is calculated by change in y over change in x
for function a, as y goes up 2 x goes up 1
so the slope ( rate of change) is 2/1
for function b is y goes up 3 x goes up 1
so the slope (rate of change) is 3/1
3/1 is greater than 2/1 so function b has a greater rate of change
So first we have to subtract 3y from 21 cause the oppisit of addition which is subtraction so you get 18y when we divide that with -8y and get y=2.25y
