Answer:
c=231.87 m
Step-by-step explanation:
When we read this example we can see that Peter will form triangle with those sides :
a=200 m,
b=180 m
cos X=cos (180-105)=cos75
x is angle.
Now, we can use this rule :
Now, let's evaluate :
Answer:
1.05 ± 0.05 lbs
Step-by-step explanation:
Hi!
We can calculate this interval with the z-score of the 90% which is (by convention) 1.645
The interval is calculated as follows:
where x_m is the mean, σ the standar deviation and n is the number of samples:
replacing these values we get:
*rounded to the first decimal*
1.05 ± 0.05
Answer:
See below
Step-by-step explanation:
<u>Given points:</u>
- S(-3,6),T(0,7),U(1,4),and V(-5,2)
<u>Translation rule: </u>
- (x,y) → (x+7,y-9)
<u>New coordinates by applying the rule:</u>
- S'(4, -3), T'(7, -2), U'(8, -5), V'(2, -7)
See attached for the graph
The blue trapezoid is STUV and the red one is S'T'U'V'
