The answer is the fourth line because it starts with 1 and then you have to subtract 3 from 1 (1-3) and you get -2
Answer:
x = 6
Step-by-step explanation:
This shows that the angle being split is 90 degrees.
<em>We know that 32 degrees are already known so we can do </em><em>90 - 32 = 58</em>
Now we know that 58 is the angle of 9x + 4
9x + 4 = 58
Subtract 4 from both sides
9x = 54
Divide both sides by 9 to isolate x
x = 6
One of the numbers is 40 and the other one is 63
confirmation:
63×(2/3)-2=40
and 40+63=103
Answer:
the standard error is 153.125
Step-by-step explanation:
given that
The random sample is 256
The sample mean is $35,420
And, the standard deviation is $2,450
We need to find out the standard error
We know that
= standard deviation ÷ √random sample
= 2450 ÷ √256
= 2450 ÷ 16
= 153.125
Hence, the standard error is 153.125
The correct answer is B. x=-8
