Answer:
N = 3/8
Step-by-step explanation:
let the number be N
let's express the word sentence as a mathematical expression:
"a number multiplied by 2/5"
= "N" multiplied by 2/5
= N x (2/5)
= (2N/5) ------- (1)
"a number multiplied by 2/5 is 3/20" can be written as:
(2N/5) = 3/20 (multiplying both sides by 5)
2N = (3/20) x 5
2N = 3/4 (divide both sides by 2)
N = (3/4) ÷ 2
N = (3/4) x (1/2)
N = 3/8
What is the interquartile Range for the following data set? {5,6,7,3,9,8,3,1,6,7,7}
mrs_skeptik [129]
To find the interquartile range of the data, you get both quartile one (1) and two (2) and subtract the larger number from the lower number.
Q3 - Q1 = Interquartile range
Your answer, in turn, would be...
4
4sin x=2sin x + √3
4sin x-2sinx=√3
2sin x=√3
sinx=√3/2
x=arcsin √3/2=π/3 + 2Kπ U 2π/3+2Kπ
Sol: π/3 + 2Kπ U 2π/3+2Kπ ; K∈Z
π/3+2Kπ=60º+360ºk
2π/3+2Kπ=120º+360ºK
