Answer:
step by step!
Step-by-step explanation:
let it be know, that ALL triangles equal up to 180 degrees. we know that triangle a has a 90 degree angle. first lets find the missing angle (purple question mark in triangle a): 25 + 90 = 115. 180 - 115 = 65.
you also know that the blue line is 180 degrees, so you can use the given measurement, 75, and the on you just found, 65, to find the last one. 65 + 75 = 140. 180 - 140 = 40 (purple question mark in triangle b).
now looking at triangle b, the given measurement, 40, and the one you just found, also 40, PLUS the ?, will equal 180. to do this you will do 40 + 40 = 80. 180 - 80 = 100.
? equals to 100 degrees.
Answer:
SE=$128.13
Step-by-step explanation:
-Given the sample mean is $34,250 and standard deviation is $2,050 with n=256:
-Standard error is calculated using the formula:
Where s is the sample standard deviation.
#We substitute our values to solve for SE:
Hence, the standard error is $128.13
Answer:
The 100th term of the sequence is 503.
Step-by-step explanation:
Given : Sequence 8, 13, 18,23, 28,...
To find : The 100th term in the sequence ?
Solution :
Sequence 8, 13, 18,23, 28,... is the arithmetic sequence
Where, First term is a=8
The common difference is d=13-8=5
The nth term of the sequence is given by
The 100th term is given by,
The 100th term of the sequence is 503.
