Answer:
C) 40% of 84
Step-by-step explanation
i don't know how to explain it T~T
Answer:
a) State the random variable
Random variable : x
which refers to a randomly selected student from the college that is left-handed.
b) state population parameter
population parameter : P
which is the percentage of all students from the college that are left handed
c) state the hypotheses
The hypothesis are;
Null hypothesis H₀ : p = 0.11
Alternative hypothesis H₁ : p > 0.11
d) State the Type I error in the context of this problem.
Type - I Error: Rejecting that the % of all the students from the college that are left-handed is 11% when actually the % is really 11%
(Reject H₀ when H₀ is true)
e) State the Type 11 error in the context of this problem
Type-II Error: Failing to Reject that the % of all the students from the college that are left-handed is 11% when the % is really higher than that
(Fail to reject H₀ when H₀ is false)
They are not similar because BR: DB is 1:2 and KE:YK is 1:3. This is due because of the slope, the slope of KE:YK is 9/3 or 3/9 which is equal to 1:3 and the slope for BR:DB is 2/4 or 4/2 which is how you get the ratio of 1:2.
Volume of the toy bouncy ball:
V = 4/3 r³ π
4.19 = 4/3 r³ · 3.14
r³ = ( 4.19 · 3 ) : ( 4 · 3.14 ) = 1
r = ∛1 = 1 in
Volume of the cube: V = a³
There are 64 toy balls. It means that there are 4 x 4 x 4 in the cube.
a = 4 · 2 r = 8 in
V = 8³ = 8 · 8 · 8 = 512 in³
Answer: B ) 512 in³
