1> distributed
10x - 40 = 20
2 > move - 40 -- + 40
10x = 20 + 40
10x = 60
3 > divide 10
x = 6
Answer:answer will vary.
Step-by-step explanation:
Your teacher will display a graph of all the students’ sample proportions of heads.
The following is an example of a sampling distribution of sample proportion of head samples from 0.25 to 0.60
Answer:
y=131°
x=53°
Step-by-step explanation:
∠ ABD and ∠ BDC are supplementary.
The sum of the supplementary angles =180 °
thus y-4+x=180...........i
x and 37° are complementary, that is, they add up to 90°
Thus, x=90-37=53°
Using this value in equation 1 we obtain:
y-4°+53° =180°
y= 180°-53°+4°
y=131°
