Answer:
Angle 1 = 10 degree, Angle 2 = 170 degree
Step-by-step explanation:
m1 + m2 = 180 degree
(x - 24) + 5x = 180
6x - 24 = 180
6x = 204
x = 34
m1 = x - 24 = 34 -24 = 10 degree
m2 = 5x = 5(34) = 170 degree
Answer:
a) probability that the sample will have between 50% and 60% of the identification correct = 0.498
b) The probability is 90% that the sample percentage is contained 45.5% and 54.5% of the population percentage
c) Probability that the sample percentage of correct identifications is greater than 65% = 0.01
Step-by-step explanation:
Sample size, n = 200
Since the brands are equally likely, p = 0.5, q = 0.5
The Standard deviation,
a) probability that the sample will have between 50% and 60% of the identification correct.
Probability that the sample will have between 50% and 60% of the identification correct is 0.498
b) p = 90% = 0.9
Getting the z value using excel:
z = (=NORMSINV(0.9) )
z = 1.281552 = 1.28 ( 2 dp)
Then we can calculate the symmetric limits of the population percentage as follows:
The probability is 90% that the sample percentage is contained 45.5% and 54.5% of the population percentage
c) Probability that the sample percentage of correct identifications is greater than 65%
P(X>0.65) = 1 - P(X<0.65)
Since they all begin with 2, you need to look for the biggest number after the decimal point, since it's 4 then 2.4 is the biggest number
Answer:
If we call our unknown value x, then we can say that
The "product of 4 and a number" is 4x
The "difference between" 4x and 6 is 4x - 6
