Is it 60 degrees or 70 degrees? because 100 + 120 = 220
360 - 220 = 140
One side looks larger than the other tho so I am not sure.
Answer:
109.33
Step-by-step explanation:
given that the population has a distribution with a mean of 110 and a standard deviation of 8
Sample size n = 40
Std error of sample mean = std dev/square root of sample size
= 
From std normal distribution table we find that 30th percentile for Z is
-0.5244
Corresponding x score =
30th percentile = 109.33663
=109.33
Answer:

Step-by-step explanation:
From the graph, the x-intercepts are;



These are root of the polynomial function represented by the given graph.
By the remainder theorem;

According to the factor theorem, if
is a factor of
, then 
This implies that;
are factors of the required function.
Hence; 
We expand using difference of two squares to obtain;

We expand using the distributive property to get;

Rewrite in standard form to obtain;

Answer:
-3
Step-by-step explanation:
5•-3=-15
4•-3=-12
-15+3=-12
Answer:
50% because 0.05 is 5% :)
