Answer:
3.24 minutes
Step-by-step explanation:
Use a calculator or chart to find the z-score.
P(Z > z) = 0.60
P(Z < z) = 0.40
z = -0.253
Find the time associated with the z-score.
z = (x − μ) / σ
-0.253 = (x − 4) / 3
x = 3.24
Answer:
d = 90°
e = 41°
f = 139°
Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)
-> f = 180° - 41°
-> f = 139°
Answer:
x<8
Step-by-step explanation:
2x+5>3x-3
2x+8>3x
8>x
You can add 5.6 and 5.9 which is 11.5 x 8 = 92 then divide that by 2 and you have 46
245, if x represents the number of minutes then you use 5 where x would be in the function so 49(5) which is 245 jumping jacks in 5 minutes.
