Answer:
12-2=10 b=10
Step-by-step explanation:
Answer:
The dog or a squirrel
Step-by-step explanation:
X/y = 2 so x = 2y
z/x = 4 so z = 4x but x = 2y so z = 4(2y) = 8y
now you have
x = 2y, z = 8y
x + y + z 2y + y + 8y 11y 11
------------ = -----------------------= ------------- = ----------- = 5 1/2
x 2y 2y 2
answer
C. 5 1/2
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.
