Answer with Step-by-step explanation:
The condition that at least 2 women are included is satisfied in the below cases:
Case 1) Exactly 2 women included
Thus the total number of ways to select the committee is
Case 2) Exactly 3 women included
Thus the total number of ways to select the committee is
Case 3) Exactly 4 women are included
Thus the total number of ways to select the committee is
Thus the total number of commitees possible are
Part 2)
If Mr and Mrs Simith are not to be both included then in that case the number of ways are the sum of
1) All cases of Mr Smith included and Mrs smith excluded
2) Mrs smith included and Mr Smith Included
Thus the cases are
X=49 because 50-1=49 so 49+1=50
Answer:
a. c = 2030,
b. n = 1.42,
c. x = 2.875,
d. k = 140
Step-by-step explanation:
a ) 8120 = 4c,
c = 8120 / 4 = 2030
b ) 0.5n = 0.71,
n = 0.71 / 0.5 = 1.42
c ) 8x = 23,
x = 23 / 8 = 2.875
d ) 7 : 6 = k : 120
Here we want to convert this ratio into fraction form,
7 / 6 = k / 120
And now we can cross - multiply to determine the value of k,
6k = 7(120) = 840,
k = 840 / 6 = 140
We can check the value of k, by plugging it back into our ratio, and see if it reduces to 7 : 6,
140 : 120,
14 : 12,
7 : 6
Answer:
The scientist’s conclusion is not appropriate because it is based on a subjective appreciation (“significantly greater than”).
<em>How “greater” is “significantly greater”?
</em>
A more objective and technical approach would be fixing a level of significance, let's say 0.05 or 0.01 for example, measuring the samples means and standard deviations and then proceeding with an appropriate hypothesis testing in order to see if the differences in means are really significant.
Step-by-step explanation:
The ratio figure b to figure a 1/3. Just times 6 by 3 and the you'll find that the volume of figure a is 18.
