1) -3•5/ 4•5 And 9•2/ 10•2 Because you want to have the same denominator. That equals -15/20 + 18/20 so you just add -15+18 to get 3/20
The answer is 3/20

I got it right
Answer:
x = 16
m<R = 34°
Step-by-step explanation:
▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.
▪︎So, you write them equal to each other and solve the linear equation to find <em>x</em><em>.</em><em> </em>
▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.
▪︎Sum of all angles in a triangle is 180°,so
146° + m< R =180°
▪︎than minus 146° from 180°.
▪︎And you will have your answer.
Answer:
15
Step-by-step explanation:
Given that:
Mean (μ) = 1500
Standard deviation (σ) = 150
Sample size = 100
Mean (m) = 1400
Margin of Error of sample :
Standard deviation / √sample size
σ / √n
150 / √100
150 / 10
= 15
The value of X=28 while the value of y=28,hopefully this is right
