Answer:
95.44%
Step-by-step explanation:
Mean (m) = 48
Standard deviation (sd) = 9
n = 12
Zscore = (x - m) /sd
X = 30
Zscore = (30 - 48) / 9
Zscore = - 2
X = 66
Zscore = (66 - 48) / 9
Zscore = 2
percentage of daily phone calls numbering between 30 and 66 = P(z < 2) - p(z < - 2)
P(z < 2) = 0.9772
P(z < - 2) = 0.0228
Hence,
0.9772 - 0.0228 = 0.9544
0.9544 * 100% = 95.44
Answer:
216°
Step-by-step explanation:
Conversion from Radians to degrees : -
( θ * 360 ) / π
θ = 3π / 5
θ = ( 3π / 5 * 360 / π )
= ( 3 * 360 * π ) / ( 5 * π )
= ( 3 * 360 ) / 5
= 3 * 72
θ = 216°
formula = height = 12+10t
where t = number of weeks
so for t10
height = 12+10(10) = 12+100 = 112 cm
for t12
height = 12+10(12) = 12 +120 = 132 cm

20, added with 5 times of 9 __ ?
No, you do not have enough flour. To solve, you would need to substitute 5 for b, and 2 * 5=10. Since you only have 8 cups of flour, you do not have enough.
