Answer:
Mary potted 26 of the plants.
Step-by-step explanation:
74 - 48 = 26
Answer:
0.066
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation
For the question
mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.
x = 2.5
Hence:
z = 2.5 - 3.27/0.51
z = -1.5098
Probability value from Z-Table:
P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) =
=0.065547
Therefore, the proportion of baby boys that are born with a low birth weight is 0.066
Answer:
750 times 6
Step-by-step explanation:
Answer:
r = 2.5
Step-by-step explanation:
the area of the whole circle = 
*π * 24
A = πr² = (13π*24)/50
r = √((13*24)/50) = 2.5 inches
Answer:
2
Step-by-step explanation:
7x4-3x8+2^2-6 : you have to do exponents 1st
7x4-3x8+4-6 : next you multiply 7x4 and -3×8
28-24+4-6 : you add -24+4
28-20-6 : you subtract 28-20
8-6 : you subtract 8-6
2 : thats your answer
sorry if I'm late
