Solution:
The table which is about kind of jeans and it's color is
Style Color
regular light blue
loose fit indigo
boot cut washed
slim fit black
slim fit blue
(a) A regular can be chosen out of five colors, A loose fit can also be chosen in five colors,Similarly a boot cut as well as slim fit can also be chosen out of five colors.
If you consider this as a relation , total number of relation that is total jeans = 1×5 + 1×5 +1×5+1×5= 20 Jeans = 10 Pairs of jeans(Possible)
(b) Total number of jeans , if i have one pair of jeans of each possible style and color = As there are 5 colors and 4 styles , the jeans are in pair = 5×4×2=40
Number of Black color jeans = 2× black color in 4 styles= 2×4=8
Probability of an event =
Probability of choosing a pair of black jeans at random=
Answer: 2.6
Step-by-step explanation:
Answer:
At 95% confidence level, the confidence interval that is likely to contain the percent, , of all teenagers at the wheel when an accident occurred is given as follows;
12.7% < < 18.6%
Step-by-step explanation:
The parameters given are as follows;
Sample size, n = 582
Proportion of accidents where teenagers are at the wheel, = 15.6%
x = 0.156*582 ≈ 91
The formula for the confidence interval is as follows;
Where:
z = z value at the confidence level
We therefore have;
At a confidence level of 95%, z = 1.96
The confidence interval at 95% confidence level is therefore;
12.7% < < 18.6%.
Answer:
Explanation:
1).
TS = UR
But TS = 18 and UR = 6x
18 = 6x
18/6 = x
3 = x
