The probability that the value selected at random is greater than 30 will be found as follows:
z-score is given by:
z=(x-mu)/sig
z=(30-30)/2=0
thus
P(x>30)=1-P(X<30)=1-P(z<0)=1-0.5=0.5
Answer P(x>30)=0.5

Step-by-step explanation:
<u>Surface Area of a Cylinder</u>
Given a right cylinder of base radius r and height h, the surface area is calculated as follows:

The cylindrical tank has a height of h=1 m and a base diameter of 140 cm. The radius is half the diameter, thus r=140/2 = 70 cm = 0.7 m. Substituting:

Answer:
the corresponding angles are equal in similar figures.
Step-by-step explanation:
When two figures are similar then the corresponding angles of the two figures are equal. the side of the figures are in proportional.
for example, when triangle ABC is similar to triangle DEF
then the corresponding angles are equal
<A=<D
<B=<E
<C=<F
so the corresponding angles are equal in similar figures.
The radius of the circle expressed as a mixed number is:
inches.
<h3>What is the Radius of a Circle?</h3>
Radius of a circle = half the measure of the diameter of a circle.
Given:
diameter of a circle =
inches
Therefore:
Radius of the circle = 1/2(
)
= 1/2(47/6)
= (1 × 47)/(2 × 6)
= 47/12
=
inches.
Therefore, the radius of the circle expressed as a mixed number is:
inches.
