Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = 
Given
secθ = - 
, then
tan²θ + 1 = (- )² = 
( subtract 1 from both sides )
tan²θ = 
( take the square root of both sides )
Since 
< θ < π and tanθ < 0 , then
tanθ = - 
Then
cotθ = 
= - 
The answer is 4. 156/34 = 4
Answer:
a range of values such that the probability is C % that a rndomly selected data value is in that range
Step-by-step explanation:
complete question is:
Select the proper interpretation of a confidence interval for a mean at a confidence level of C % .
a range of values produced by a method such that C % of confidence intervals produced the same way contain the sample mean
a range of values such that the probability is C % that a randomly selected data value is in that range
a range of values that contains C % of the sample data in a very large number of samples of the same size
a range of values constructed using a procedure that will develop a range that contains the population mean C % of the time
a range of values such that the probability is C % that the population mean is in that range
Answer:
x² - 10x + 24
Step-by-step explanation:
(x -4)(x - 6)
To write this in standard form, we need to FOIL the binomials.
FOIL: first – outer – inner – last
F: x • x = x²
O: x • -6 = -6x
I: -4 • x = -4x
L: -4 • -6 = 24
Combine the new terms.
x² - 6x - 4x + 24
Combine like terms.
x² - 10x + 24
This is your polynomial in standard form.
Hope this helps!
Answer:
$22.34
Step-by-step explanation:
really simple.
just multiply the number by how much the coin is worth
24 x 1 = 24
62 x 5 = 310
55 x 10 = 550
16 x 25 = 400
19 x 50 = 950
then add all of them
24 + 310 + 550 + 400 + 950 = 2234
and finally divide it by 100
2234 ÷ 100 = 22.34
and just pop in a dollar sign
$22.34
