Answer:
the slope (m) = 3/4
Step-by-step explanation:
To find the mean (fair share/average) of the data set, you will combine all the numbers (add) and then split them into the same number of groups you started with (divide by 10).
1320/10 = 132
The mean is 132.
It’s c i think or can be d but my best bet is c !!
<span>4 is 80% of x = 5
4/80*100=5</span>
Answer:
<h2>See the explanation.</h2>
Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).
It is given that tanα=3.
Sinα(Sinα) = 
[
], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α = 
.
Cos4α =
