You want to compute the total area of the figure. The figure is composed by four 6x4 rectangles, and two 4x4 squares.
The area of one rectangle is 
The area of one square is 
You have four rectangles and two squares, so the answer is
The two triangles are the same.
Find the third angle of the triangle on the bottom.
All 3 angles of a triangle add up to 180.
65 + 65 = 130
Now subtract it from 180:
180 - 130 = 50
So 'x' is equal to 50 degrees.
0.5*x+0.6*y=0.6(200) where x is quantity of 1st and y is 2nd vinegar.
so, 5x+6y=6(200)=1200
5x+6y=1200......(1)
x+y=200..........(2)
(1)-5*(2)⇒y=1200-1000=200,x=0
so, you just take 200 ml of second vinegar. In fact, this calculation can be skipped coz we were asked the 2nd vinegar directly in the question.
Answer: option A is correct, we accept the null hypothesis.
Step-by-step explanation:
At a 5% level of significance, p = 0.05, therefore when p < 0.05, accept the null hypothesis (H°) and reject the alternative hypothesis (H¡). When p > 0.05, we reject the null hypothesis (H°) and accept the alternative hypothesis (H¡)
Given the p-value to be 0.008, this is less than the 5% threshold, that is, 0.05, hence we accept the null hypothesis.
