Answer:
The length of AB is 7.45 units.
Step-by-step explanation:
You can find the length of AB using Cosine Rule, cosθ = adj./hypo. :
θ = 20°
adj. = 7 units
hypo. = AB
cos 20° = 7/AB
AB = 7/cos 20°
= 7.45 units (3s.f)

Answer:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Step-by-step explanation:
The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.
The average number of newspapers for sale in an airport stand is 15. SD is 6.
The consistency is:
The average age of the pilots is 36 and SD is 4.
The consistency is:
The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.
Well If I did my math correctly, they should've made $26.39, considering you would add the 67 cents to the total $25.72
N-6/n²+11n+24/n+1/n+3
First, we need to factor the following:
n² + 11n + 24 → (n + 3)(n + 8)
n² → n * n
factor of 24 are:
1 x 24
2 x 12
3 x 8 We will use these factors. 3 + 8 = 11
4 x 6
Division involving fractions results to multiplying the first fraction to the reciprocal of the second fraction.
n-6/(n+3)(n+8) * n+3 / n+1 → n+3 is in both numerator and denominator. Cancel each other out.
n-6/n+8 * 1/n+1
n-6/(n+8)(n+1) Correct answer is Choice D.
