Multiply the z-score by the standard deviation:
2 x -1.5 = -3
Now add that to the mean:
49 + -3 = 46 inches.
Answer:
The answer is 9.2 * 10^7
Step-by-step explanation:
(1.5*10^8)-(5.8*10^7)=92,000,000
92,000,000= 9.2* 10^7
Step-by-step explanation:
The data is already in ascending order.
The lower half of the data (120, 140, 160)
has the median 140.
180 is the median of the entire data.
The upper half of the data (200, 220, 240)
has the median 220.
Interquartile Range = 220 - 140 = 80.
Answer:
10 feet
Step-by-step explanation:
a^2+b^2=c^2
15^2+B^2=365
225+b^2=365
b^2=100
b=10
Answer:
−28+28
Step-by-step explanation:
1)Rearrange terms
(−4+4)(−7)
(4−4)(−7)
2)Re-order terms so that constants are on the left
(4−4)(−7)
−7(4−4)
3)Distribute
−7(4−4)
−28+28
Solution
−28+28
