Answer:
Step-by-step explanation:
.
Answer:
1. P= 80
60/.75=80
2. x= 5/3
-27/25x / -27/25= -9/5 / -27/25
-9/5 / -27/25 --- -9/5 x -25/27
3. -300
-2.7/-2.7 = 810/-2.7
4. 120
84x100/70
<u>84/x = 70/100</u>
Answer:
b) μ = 2 and σ = 1.29
Step-by-step explanation:
<u><em>Step(i):-</em></u>
<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>
<em>Given that the probability of labelled '1'</em>
<em> </em> =0.16
<em> q = 1-p = 1- 0.16 = 0.84</em>
Let 'X' be a random variable in binomial distribution
The mean of the binomial distribution
μ = n p
μ =
<em>The mean of the binomial distribution = 2</em>
<u><em>Step(ii):-</em></u>
The standard deviation of X
σ
σ =
σ =
<em>The standard deviation of the binomial distribution</em>
<em> </em> σ =

Answer:
B. 152 + 7
Step-by-step explanation:
(8x + 16) + (7x - 9)
8x + 16 + 7x - 9
15x + 16 - 9
15x + 7
None of these options have this answer, so we see A and B:
A. x + 7
B. 152 + 7
It can't be A because we have 15x and A is x + 7
By process of elimination we have B. 152 + 7
x = 10 and 2/15
