Answer:
B
Step-by-step explanation:
There is a difference of 2 between consecutive odd integers.
let n , n + 2 and n + 4 be the 3 consecutive odd integers, then
n + n + 2 + n + 4 = 87 , that is
3n + 6 = 87 ( subtract 6 from both sides )
3n = 81 ( divide both sides by 3 )
n = 27, n + 2 = 27 + 2 = 29, n + 4 = 27 + 4 = 31
Thus
The 3 consecutive odd integers are 27, 29, 31 → B
Answer:
Justice lived in Germany for 15 months and he lived in Holland for 9 months.
Step-by-step explanation:
1. You must make a system of equations:

Where
is the number on months he lived in Germany and
is the number on months he lived in Holland.
2. You can solve this system of equations by using the Elimination Method. If you multiply the first equation by -120, you can cancel the variable
when you add both equations, and then you can calculate
. When you obtain the value of
, you can substitute it into one of the original equations and solve for
. Then:

Using the given information, the value of Σfd is 800
<h3>Calculating mean using Assumed mean </h3>
From the question, we are to determine the value of Σfd
The formula for mean, using the assumed mean method is given by

Where
is the mean
A is the assumed mean
From the given information,



Putting the parameters into the equation, we get





Hence, the value of Σfd is 800

Answer:
599/711
Step-by-step explanation:
Band Sports Debate Total
Male 105 320 7 432
Female 105 160 14 279
Total 210 480 21 711
P(female or plays sports)
We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them
P(female) + P (sports) - (female and sports)
female/total + sports/total - female sports/ total
279/711 + 480/711 - 160/711
599/711
