Answer:
120
Step-by-step explanation:
Is means equals and of means multiply
W = 30% * 400
Change to decimal
W = .30*400
W = 120
Answer:
1000
Step-by-step explanation:
x = 1, y = -1, and z = 2
Answer:
768
Step-by-step explanation:
Answer:
x = 2.24
Step-by-step explanation:
I will ASSUME that the 15 represents the angle in degrees
We can make a similar triangle by adding the purple lines as shown.
Any triangle inscribed in a circle with one side as a diameter is a right triangle.
We know it is similar triangle because it shares two common angles, the right angle and the 75° angle at the far right. Then
z = 2Rsin15 = 2(16.7)sin15
x = zsin15 = 2(16.7)sin²15 = 2.237375756799...
Z-score formula is z=(x-m) / sd
x = data value
m= mean
sd = standard deviation
z= (82-78.2) / 6.7
=0.567
=0.57
