Answer:
mathematics questions and then you solve your questions
Answer:
1.3
Step-by-step explanation:
BC is the distance between B and C.
BC = x − (-0.4)
BC = x + 0.4
AB is the distance between A and B.
AB = -0.4 − (-1.25)
AB = -0.4 + 1.25
AB = 0.85
Substitute into the equation.
BC = 2AB
x + 0.4 = 2(0.85)
x + 0.4 = 1.7
x = 1.3
Tricky one! Since we are not given any lengths I will use my intuition.
4*4/2 = 8
5*5=25
(25-8)/25 = 17/25 = 68%
Am I right? Is my intuition correct/ please tell me so thanks!
7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.
Answer:
option A
Step-by-step explanation:
To Test
H₀ : μ = 3.75
H₁ : μ ≠ 3.75
now,
If μ = 3.95 then it means H₀ is not true.
then the probability is rejecting the null hypothesis.
Hence, the probability is the power of the test against the alternative μ=3.95
The correct answer is option A
