:)
70 for the first one I can’t figure out the rest I’m so sorry
M=-2. 3.5 x -2 = -7 and -7 + .75 would = -6.25
Answer:
\mu = 41.1091, 43.6109
Step-by-step explanation:
given data sets
40.2,43.1,45.5,44.5,39.5,40.2,41.0,41.6,43.1,44.9
sample mean = (sum of all value / number of value)
sample mean = 423.6/10 = 42.36
standard deviation = 2.158 given
t =1.833 for 90% confidence interval at df = n-1 = 9
90% confidence interval is given as
\mu = 41.1091, 43.6109
Answer:
Step-by-step explanation:
Hello There!
The following angles are complementary angles
Complementary angles have a sum of 90
So to solve for the variable (x) we use this equation
90 = 35 + 4x + 7
step 1 combine like terms
35+7=42
now we have
90 = 4x + 42
step 2 subtract 42 from each side
90 - 42 = 48
42 - 42 cancels out
now we have
48 = 4x
step 3 divide each side by 4
4x/4 = x
48 / 4 = 12
we're left with x=12
