Answer:
The answer is...
Step-by-step explanation:
2/4
3^3 the answer is the first one with the exponent 3
Answer: (a) mean = 32.00
(b)Standard error = 0.068
It is expected that the shape will approximately large because n is large.
(c)P(z< 0.60)= 0
Step-by-step explanation:
a. Mean = nP= 0.64× 50 = 32.00(2dp)
P= 0.64
b. Standard error = √ p(1-p)/n
= √0.64(0.36)/50
= 0.068(3dp)
c. Using P(Z<X - U/S)
Where S = standard error
U = mean = 0.64
(c)P(z< 0.60)=
= P( z< 0.60 - 0.64/0.068)
= P( z < -5.88)
= 0.
Answer:
x=19.998
y=3.333
Step-by-step explanation:
5x+6y=50
-x+6y=26
6y=26+x
x=26-6y
5(26-6y)+6y=50
130-30y+6y=50
130-50=30y-6y
80=24y
y= 3.333
x=26-6y
x=26-(6×3.333)
x=19.998
