Answer:
Mean of the population having 6"-9" Hatching =38
Standard Deviation =4
Step-by-step explanation:
Confidence interval of 95% means that 95% of data lie within two standard deviations.
That is data values lie between 38-2×4 to 38 +2×4.
⇒Which is 38-8 to 38+8.
⇒30 to 46.
it is also given that margin of error is 2.5%.
So, the data value will lie between
Mean of beginning value to extreme value of 95% confidence level
So, Sample mean of this observation having 2.5% margin of error = 38
Option D:→ 38
Answer:
(x+1) (x^2+1)
Step-by-step explanation:
x^3+x^2+x+1
Factor by grouping
x^3+x^2 +x+1
Factor out x^2 from the first group and 1 from the second group
x^2( x+1) + 1( x+1)
Factor out (x+1)
(x+1) (x^2+1)
3 (15-6)+(18-12)^2=
3 (9) + (6)^2=
27 + 36 =
63
The correct answer is Choice A) 367,274.
The chart for this data starts in the year 1960. We are looking for the population during year 2010. That is 50 years later.
To find the answer, just input 50 for t in the equation.
P(50) = 200(1.01223)^50
Answer:
The value of x is 10, and the value of y is 6
Step-by-step explanation:
ABC and GEF are congruent
so
x - 8 = 2
x = 10
x - y = 4
10 - y = 4
y = 10 - 4
y = 6
Answer
x = 10, y = 6
