Answer:
Step-by-step explanation:
is the central angle.
0.308 rounded to the nearest hundredth would be 0.31 .
Answer:
Step-by-step explanation:
0.333333 = 1/3
can check through dividing 1 by 3
0.125 = 125/1000 = 25/200 = 5/40 = 1/8
0.166666 = 1/6
0.1 = 1/10
0.66666 = 2/3
0.2 = 2/10 = 1/5
0.75 = 75/100 = 15/20 = 3/4
Louise wants to factorize completely the given polynomial
Grouping first, second terms together and third, fourth terms together
=
Taking common from first and second terms of the given expression and taking 5 common from the third and fourth terms.
=
Taking (x+3) common from the given expression,
= is the completely factored form.
According to the 3:1 ratio, you expect, out of a population of 1000 people, 750 non-hemophilia and 250 hemophilia.
The chi-square value can be calculated by the formula:
where:
O = observed value = 210
E = expected value = 250
Therefore:
χ² = (210 - 250)² / 250
= 6.4
Now, look at a χ<span>² distribution table, in order to find the p-value. In this case, you have only 1 degree of freedom and the closest </span>χ<span>² is 6.6 which corresponds to a p-value of 0.01.
Since p < 0.05, which is the minimum value generally accepted, we can say that the data do not support the hypothesis.</span>
