Answer: 1436 units cubed (3.14) or 1437 units cubed (π)
Step-by-step explanation:
answer depends on if you substitute in 3.14 for π or not
Given:
n = 27, sample size
df = n-1 = 26, degrees of freedom
xb = 11.8, sample mean
s = 2.3, sample standard deviation.
Because population statistics are not known, we should use the Student's t-distribution.
At 99% confidence interval, the t-value = 2.779 (from tables).
The confidence interval is
11.8 +/- 2.779*(2.3/√(27)) = 11.8 +/- 1.23 = (10.57, 13.03)
Answer: (10.6, 13.0) to the nearest tenth
You first need to isolate either x or y. since in one formula has both x and y in it and there is one with only y, you should solve the smaller one first then plug and chug
Answer:
Yes!
Step-by-step explanation:
6: 8: 10, makes a ratio of 3: 4: 5, making a right triangle
The growth formula is:
y = a•(1+x)^(t/p)
y is the end result
a is the initial amount
x is the percent growth as a decimal
t is the total amount of time
p is how often the growth occurred
Note that t and p both need to be the same units, whether that be seconds or days or months or years etc.
So,
y = 380000 • (1.065)^(10/1)
y = 380000 • 1.87713746527
y = 713312.236802
y = 713312
