Answer:
The approximate probability that more than 360 of these people will be against increasing taxes is P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
The right answer is B.
Step-by-step explanation:
According to the given data we have the following:
sample size, h=600
probability against increase tax p=0.45
The probability that in a sample of 600 people, more that 360 people will be against increasing taxes.
We find that P(P>360/600)=P(P>0.6)
The sample proposition of p is approximately normally distributed mith mean p=0.45
standard deviation σ=√P(1-P)/n=√0.45(1-0.45)/600
If x≅N(u,σ∧∧-2), then z=(x-u)/σ≅N(0,1)
Now, P(P>0.6)=P(<u>P-P</u> > <u>0.6-0.45)</u>
σ √0.45*0.55/600
=P(Z> <u>0.6-0.45)</u>
√0.45*0.55/600
Yeah I think so you have to solve and break it down
It's 10. I hope this helps!
Answer:
Step-by-step explanation:
Finn earns $5 for each crate of oranges he sells in a week. This means that if she sold z crates in a week, the total amount that she would earn is 5 × z = 5z
At the end of the week, Ellie has earned $20 more than Finn. The following expression shows Ellie's earnings :
20 + 5z
Therefore, in the expression, the second term represents the total amount that Finn earned for selling z crates.
Mr. Rowley
16:14
Ms. Rivera
64:60
If you try to simplify 64:60, you get 16:15.
64/4 = 16
60/4 = 15
So they are not equivalent because Ms. Rivera has 1 more exit ticket than Mr. Rowley.
