Answer:
the number of additional she needed is 135
Step-by-step explanation:
The computation is shown below:
GIven that
40 flowers of 16%
So for 100% it would be
= 40 ×100 ÷ 16
= 250
Now she needs to make is
= 70% - 16%
= 54%
Now the additional would be
= 250 × 54%
= 135
Hence, the number of additional she needed is 135
Answer:
0.02493
Step-by-step explanation:
We are to Find :
P(p > 0.12) ;
This is equivalent to:
1 - P(p ≤ 0.12)
Using the relation :
1 - P((p - po) / (√(po(1 -po)) / n))
1 -P((Z ≤0.12 -0.09) / (√(0.09(1 -0.09)) / 350))
1 -P((Z≤0.03 / (√(0.09(0.91))/350))
1 - P((Z≤0.03 / 0.0152970))
1 - P((Z≤1.96116)
1 - 0.97507 (from Z probability calculator)
= 0.02493
Answer:
15.6.
Step-by-step explanation:
5-44• (-0.75) - 18 ÷ 2/3 • 0.8 + (-4/5)
= 5 + 33 - 27*0.8 - 0.8
= 5 + 33 -21.6 - 0.8
= 15.6.
Answer:
m(∠LMN) = 67.44°
Area of ΔMNL = 16.66 square units
Step-by-step explanation:
By applying Sine rule in the ΔLMN,
SinM = 
SinM = 0.9235
M = 
M = 67.44°
m(∠M) + m(∠N) + m(∠L) = 180°
67.44 + 38 + m(∠L) = 180°
m(∠L) = 180 - 105.44
m(∠L) = 74.56°
Area of ΔMNL = 
= 
= 16.66 square units
