Answer:
-7π/3 or -420 degrees
Step-by-step explanation:
So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.
The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.
π/2 - π/6
3π/6 - π/6 = 2π/6
π/3
Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Answer:
option (a) It will be closer to 30 than to 20
Step-by-step explanation:
Data provided in the question:
For sample 1:
n₁ = 10
variance, s₁² = 20
For sample 2:
n₂ = 15
variance, s₂² = 30
Now,
The pooled variance is calculated using the formula,
on substituting the given respective values, we get
or
= 26.0869
Hence,
the pooled variance will be closer to 30 than to 20
Therefore,
The correct answer is option (a) It will be closer to 30 than to 20
Answer: P = $ 1,998.01
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 24%/100 = 0.24 per year,
putting time into years for simplicity,
1 months ÷ 12 months/year = 0.083333 years,
then, solving our equation
P = 39.96 / ( 0.24 × 0.083333 ) = 1998.007992032
P = $ 1,998.01
The principal required to
accumulate interest of $ 39.96
on a rate of 24% per year for 0.083333 years (1 months) is $ 1,998.01.
