Answer:
0.1052
Step-by-step explanation:
Given that proportion of germination in the population is 94% =0.94
p = 0.96
Sample size = 220
Std dev of p = 
The probability that more than 96% of the 220 seeds in the packet will germinate
= 
Assumptions are np and nq >5 and also sample size >220 hence normal
Answer:
Step-by-step explanation:
10 in 10 places is 100. 10*1=10. 10*2=20..10*3=30.10*4=40,. 10*5=50,10*6=60,,,10*7=70,,. 10*8=80,. 10*9=90,. 10*10=100.
Answer:
x = -0.4
Step-by-step explanation:
Answer:
x=2,x=7
Step-by-step explanation:
-3x^2+27x=42
x^2-9x+14=0
x^2-2x-7x+14=0
x*(xi2)-7(x-2)=0
(x-2)*(x-7)=0
x-2=0
x-7=0
x=2
x=7
Answer:
w= 9 3/4
Step-by-step explanation:
4 1/5 =21/5
13 19/20= 279/20
w+21/5 + 279/20
-21/5 -21/5
w+39/4
w=9 3/4
