Answer:
A = 55 in²
Step-by-step explanation:
We can consider the outside rectangle and subtract the indented rectangle.
area of outer rectangle = 7 × 10 = 70 in²
area of indented rectangle = 3 × 5 = 15 in²
A of figure = 70 - 15 = 55 in²
79 because from year 1 to year 3 it went up by 22 so you can predict it will go up by another 22
Answer:
The original cost is $350
Step-by-step explanation:
Let's assume
original cost of computer is x
There is a 10% off sale on laptop computers
So, amount saved is
now, we are given
someone saves $35 on a laptop
so, we can set them equal
and then we can solve for x
we can divide both sides by 0.10
and we get
So,
The original cost is $350

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
