Answer:
D
Step-by-step explanation:
The sum of supplementary angles is 180°
To find the supplement of 60° subtract it from 180°, that is
second angle = 180° - 60° = 120° → D
Answer:
0.1007
Step-by-step explanation:
Given :
Average gain, μ = 0.8
Standard deviation, σ = 0.7
Number of companies, n = 20
Obtaining the standardized value ;
Zscore = (x - mean) / (σ/√n)
Zscore = (1 - 0.8) / (0.7/√20)
Zscore = (0.2 / 0.1565247)
Z = 1.27775
Using the Z probability calculator :
P(Z > 1.27775) = 0.10067
P(Z > 1.27775) = 0.1007 ( Z probability calculator)
Answer:
Step-by-step explanation:
Look at the 3rd decimal digit (the digit after the hundredths).
- if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;
- However if it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after it
For example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.
I hope this helps ^^
Answer: 3.45
Step-by-step explanation:
Answer:
a.) (x-3)(x-3) = 25 + (x-4)(x-4)
x^2 - 6x + 9 = 25 + x^2 - 8x + 16
-6x + 9 = -8x + 41
2x + 9 = 41
2x = 32
x = 16
b.) 16 - 4 = 12
AB = 12
c.) 16 - 3 = 13
AC = 13
[btw I don't know if this is the method your teacher wants as it does not use the similar triangle :/ but it is still correct :) so good luck bro]
