Concrete can be purchased by the cubic yard. How much will it cost to pour a slab 11 feet by 11 feet by 2 inches for a patio if

Elena-2011 [213]

Answer:

$34.04

Step-by-step explanation:

The dimensions of a slab is 11 feet by 11 feet by 2 inches or 3.67 yards, 3.67 yards and 0.055 yards

We need to find the cost to pour a slab.

We know that the volume of a cuboid shape is given by :

V = lbh

Put all the values,

V = 3.67 × 3.67 × 0.055

V = 0.74 yards³

Cost,

C = $46 × 0.74

C = $34.04

Hence, the required cost is equal to $34.04.

Find the probability of at least 2 girls in 8 births. assume that male and female births are equally likely and that the births

Afina-wow [57]

At least two girls means either 2, 3 ... or 8 girls.
Using the binomial law, we can write the probability in the form:
B(2,0.5)+B(3,05)+...+B(8,0.5)= $0.0039(C_8^2+...+C_8^8)$
Continue simplifying:
$C_8^2+...+C_8^8=2^8-C_8^1=2^8-8=248\\\text{We deduce the probability of the event "at least two girls in birth ":}\\0.0039\times248=0.96\\\text{The above probability (0.96) means that the event is very likely}$
