139.49
Step-by-step explanation:
using trig ratios.
tan=o/a
tan74°=n/40
40tan74°=n
use calculator to solve
=139.49
hope this helped :)
Here's the solution ~
Now we will use this identity in denominator
[ a² - b² = (a + b)(a - b) ]
2.408 Rounded to the nearest hundredth's place is 2.41
Answer:
Combine like terms
Step-by-step explanation:
-2x+4x=2x
6+5=11
So the answer is 2x+11
A. we use the z statistic to solve this problem
z = (x – u) / s
We calculate the value of the sample mean u and standard deviation
s:
u = $30 * 304 = $9120
s = $21 * 304 = $6384
z = (9,600 – 9120) / 6384
z = 0.075
From the normal tables using right tailed test,
P = 0.47
B. At worst 11% means P = 0.11, so the z value at this is
z = -1.23
-1.23 = (x – 9120) / 6384
x = 1267.68
