Suppose a normal distribution has a mean of 266 and a standard deviation of
12. What is P(x> 242)?
O A. 0.16
B. 0.475
C. 0.84
D. 0.975
0.975 is P(x ≥242) with a mean of 266 and standard deviation of 12
The required value of P(x> 242) = is 0.975 for normal distribution. Option D is correct.
The normal distribution has a mean of 266 and a standard deviation of
12. What is P(x> 242) is to determine.
Whata is normal distribution?Normal distributions can be altered to standard normal distributions by the formula:
Z = (X - μ)/σ
Where x is a value from the initial normal distribution, μ is the mean of the initial normal distribution, and σ is the standard deviation of the initial normal distribution. The standard normal distribution is periodically called the z distribution.
Now,
z = X - 266 /12
p(x > 242) = P [(X - 266)/12 ≥ (242 - 266)/12]
p(x > 242) = P [z ≥ -24/12]
p(x > 242) = P [z ≥ -2]
p(x > 242) = P [z ≤ 2]
p(x > 242) = 0.975 (from Z table).
Thus, the required value of P(x> 242) = is 0.975. Option D is correct.

One year, the population of a city was 127,000. Several years later it was 129,540. Find the percent increase.
Answer:
2%
Step-by-step explanation:
Answer: 2%
Step-by-step explanation: Method 1
Express the ending population as a percentage of the starting population:
127000 /129540= 1.02
1.02×100= 102%
Subtract the starting 100% to get the percent increase:
102%−100%= 2%

Suppose that mean retail price per gallon of regular grade gasoline is $3.45 with a standard deviation of $0.10 and that the retail
price per gallon has a bell-shaped distribution.
NOTE: Please use empirical rule approximations for this problem.
a. What percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon (to 1 decimal)?
Lololo
%
b. What percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon (to 1 decimal)?
%
c. What percentage of regular grade gasoline sells for less than $3.55 per gallon (to 1 decimal)?
%
The percentage of regular grade gasoline sells for between $3.35 and $3.55 per gallon is 64%
The percentage of regular grade gasoline sells for between $3.35 and $3.65 per gallon is 81.5%
The percentage of regular grade gasoline sells for less than $3.55 per gallon is 84%
Given :
Mean retail price is $3.45
Standard deviation is 0.10
Empirical rule states that 99.7% of data is observed in normal distribution that lies within 3 standard deviations.
68% of data lies under 1 standard deviation
95% lies under 2 standard deviations
99.7% lies under 3 standard deviations
there are 3 standard deviations on the left and right of mean . The graph is attached below
Mean is 3.45. standard deviation is 0.1
3.45+0.1=3.55
3.45-0.1=3.35
So 3.35 and 3.55 lies under first standard deviation
The percentage between $3.35 and $3.55 is 68%
3.45 +0.1+0.1=3.65
3.35 lies on 1 standard deviation on left and 2 deviations on the right of mean
So , 34+34+13.5=81.5%
The percentage between $3.35 and $3.65 is 81.5%
For gasoline sells for less than 3.55 , there are 3 standard deviation on the left of mean and 1 standard deviation on the right
0.15+2.35+13.5+34+34=84%

Please Help on this Geometry question
Answer:
50 degrees
Step-by-step explanation:
You can see that angle ADC is composed of angle ADB and angle BDC
Angle ADB is 38 degrees and angle BDC is 12 degrees
Therefore angle ADC is 50 degrees
Angle ADC is opposite from angle ABC so they are congruent.
So angle ABC is 50 degrees
A bakery sells taro, red bean and green tea pues. 65% of the pies are taro pies. 40% of the remaining pies are red bean pies. How many pies are there altogether?
Answer: 1,800 pies in total
Step-by-step explanation:
A key detail missing is that there are 378 green tea pies.
Assuming the total number of pies is x.
65% of this is taro pies. This leaves 35% to be red bean pies and green tea pies.
If 40% of this remaining 35% are red bean pies, that means that 60% are green tea pies.
= 35% * 60%
= 21% of the total are green tea pies
There are 378 green tea pies and this is 21% of the total number of pies.
378 = 0.21 * x
x = 378 / 0.21
= 1,800 pies in total
