Step-by-step explanation:
2.3×10⁵< 8.5×10⁵< 5.5×10⁷< 3.6×10⁸< 8.1×10⁸< 7.2×10⁹.
hope this helps you.
From each further number given to you, the bigger the category, subtract the previous from the given. Example: all numbers about students who studies two branches of science will be subtracted by 7 because among those given numbers, 7 studies all three.
Answer:
y=3 and x= 9/2
Step-by-step explanation:
Answer:
c is the same angle as a
b and d are the same as the other
and together the are what's left from 360° after a and c got their share
so
360 -98 -98 = b + d
makes
164 = b + d
since they are of equal value, just decide 164 by 2 and you got b and d at once

Answer:
A) (4.0252, 4.0448).
B) (4.0331, 4.0369).
C) If i saw a sample mean of 4.020, i would conclude that the sample came from a population that did not have
a population mean equal to 4.035
Step-by-step explanation:
A) We know that an approximate 95% confidence interval for the item in question is given by the equation; ± 1.96σ
Now, since we have a mean of 4.035 mm and a standard deviation of 0.005 mm, we can solve;
± 1.96 = 4.035 ± (1.96 × 0.005) =4.035 ± (0.0098)
= 4.0252 or 4.0448 and it can be written as;(4.0252, 4.0448).
B) . We also know that In the large-sample case, a 95% confidence interval estimate for the population mean is given by the formula;
± ((1.96)/
√
)
Thus, if we solve, we get;
= 4.035 ± (1.96 ×
0.005
)/√25
= 4.035 ± 0.0019
or (4.0331, 4.0369).
c. If i saw a sample mean of 4.020, i would conclude that the sample came from a population that did not have
a population mean equal to 4.035 because it doesn't fall into the range of confidence intervals we got earlier.
