Answer:
9220
Step-by-step explanation:10^3 = 1000 then times it by 9.22 and you should have 9220
C is the one that multiplies to a negative number because
A multiples to positive 1
B also multpilies to positive 1 and d multiples to 0
A negative multiplied by a negative is a positive
A netative multiplied by a positive is a negative
Answer:
1,539
Step-by-step explanation:
Using Simple Random Sampling in an infinite population (this is such a large population that we do not know the exact number) we have that the sample size should be the nearest integer to
where
<em>Z= the z-score corresponding to the confidence level, in this case 90%, so Z=1.645 (this means that the area under the Normal N(0,1) between [-1.645,1.645] is 90%=0.9)
</em>
<em>p= the proportion of young urban people (ages 21 to 35 years) who go to at least 3 concerts a year= 35% = 0.35
</em>
<em>q = 1-p = 0.65
</em>
<em>e = the error proportion = 2% = 0.02
</em>
Making the calculations
So, the sample size should be 1,539 young urban people (ages 21 to 35 years)
Step-by-step explanation:
T = k * sqrt(d), where k is a real constant.
When d = 6, T = 5.
k = T / sqrt(d) = 5 / sqrt6.
Therefore when d = 3, T = (5 / sqrt6) * sqrt3 = 3.53.
Answer:
it is not a function because the input 5 (x) has more than one output (y)
domain (5,-1,8)
range (2,6,-2,3)
