Step-by-step explanation:
Answer: 34/10=3.4 The estimated quotient is 3.4
Step-by-step explanation: Basically, you are dividing 33.7 by 9.5, but first you will need to round to the nearest whole number. A whole number does not contain a decimal. 33.7 rounded to the nearest whole number is 34. 9.5 rounded to the nearest whole number is 10. So, you are dividing 34 by 10. 34 divided by 10 is 3.4.
12. Because it needs to be 12
Answer:
13.1%
Step-by-step explanation:
Given:
N = 200
P= 0.34
0<= x <=60
x= number of hits.
n=total times at bat
In order to find mean, we take the product of n and p, therefore:
mean 'μ' = np = 200 x 0.34 = 68
next is to find standard deviation, i.e the square root of the product of n, p and q
where q is 1-p
SD 'σ' = sqrt(npq) = sqrt(68*0.66) = 6.6993
applying continuity correction,
z = (x - μ) / σ
z = (60 - 68) /6.6993 = - 1.12
For the normal standard distribution,
P(z < - 1.12) = 13.14% => 13.1%
Answer:
∠ AOB = 139°
Step-by-step explanation:
Since AOC is a straight line then
∠ AOB + ∠BOC = 180° , that is
8x + 51 + 6x - 25 = 180
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Then
∠ AOB = 8x + 51 = 8(11) + 51 = 88 + 51 = 139°
