Answer: x = 92, y = -119
Step-by-step explanation:
Opposite sides of a parallelogram are equal.
x + 6 = 98
x = 92
127 = -y + 8
-y = 119
y = -119
You didn’t post the options but that is also equal to 1.0 x 10^-6
Answer:
270 degrees because 1/4 of a circle is 90 degrees
Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
