Required probability is 0.8990
Given that,
p = 0.44
1 - p = 0.56
n = 736
0.01830
Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.
P(0.14<
<0.47) = P((0.41-0.44)/0.01830) < 
<(0.47-0.44)/0.01830
Using normal algebra we get:
= P(-1.64 < z < 1.64)
= P(z < 1.64) - P(z < -1.64)
= 0.9495 - 0.0505
= 0.8990
Thus, required probability is 0.8990

Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
Collect the like terms
-12x=24
Divide both sides
X=-2
Answer:
C) aₙ = aₙ₋₁ + 200
Step-by-step explanation:
Each term is 200 more than the previous term. So:
aₙ = aₙ₋₁ + 200
Answer:
There was a 1% overall decrease
Step-by-step explanation:
1. you have to add 80 to 95 to get the original number of members which is 175
2.because there was a 15% increase of 80 boys you have to do 80*.15 which gets you 12 so you have to add twelve to eighty to get the new number of boys
3.next you have to do the same exact thing to the girls team but because its a decrease in girls you have to subtract the number you get after multiplying 95*.2 to get the next years number of 76 current girl members.
4.next you have to add 76 to 92 to get 168
5.then you have to divide 168 by 175 to get .96 decrease which you have to round up to a 1% decrease
