It is B because yiu solve
Get unknowns on one side and know on other side.
Divide both sides by -2
X= -7
Answer:
Step-by-step explanation:
Given that a survey showed that 72% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight
X - number of people who need correction for their eyesight
X is binomial since each event is independent and there are only two outcmes.
X (18, 0.72)
Required probability = the probability that no more than 1 of them need correction for their eyesight.
=P(X=0)+P(X=1)=0.00000296+0.000137
=0.00014
Yes 1 is a significantly low number as probability is almost zero.
The surface area of the cube-shaped wooden chest which has the side edges of 4 feet shown is 96 square inches.
<h3>What is the surface area of a cube?</h3>
Surface area of cube is the sum of the area of each face by which it is enclosed. The surface area of cube can be calculated with the following formula;
![A=6a^2](https://tex.z-dn.net/?f=A%3D6a%5E2)
Here, (<em>a</em>) is the length of side of the cube.
You want to stain the lateral faces of the wooden chest shown. Find the area that you want to stain in square inches.
A cube-shaped wooden chest with side edges of 4 feet. Thus the surface area of it is,
![A=6a^2\\A=6(4)^2\\A=96\rm\; ft^2](https://tex.z-dn.net/?f=A%3D6a%5E2%5C%5CA%3D6%284%29%5E2%5C%5CA%3D96%5Crm%5C%3B%20ft%5E2)
Thus, the surface area of the cube-shaped wooden chest which has the side edges of 4 feet shown is 96 square inches.
