Answer:
1. = 3.143
2. Circumference
3. Area of the circle is 3850 .
ii. Circumference of the circle is 220 cm.
Step-by-step explanation:
The area, A, and the circumference, c, of a circle can be determined respectively by:
A =
C = 2r
where r is the radius of the circle.
1. the ratio of the circumference and diameter, D, of a circle is:
r =
so that,
C = 2
C = D
=
=
= 3.143
2. The distance around a circular region is known as it's circumference.
3. Given a circle of radius 35 cm, then:
A =
= x
= x 1225
= 22 x 175
A = 3850
Area of the circle is 3850 .
C = 2r
= 2 x x 35
= 2 x 22 x 5
= 220
C = 220 cm
Circumference of the circle is 220 cm.
Answer:
3.35 decimeter.
Step-by-step explanation:
We have been given that the first week, the plant's height measured 2.65 Decimeters. During the second week, Tania''s plant grew 0.7 Decimeter.
To find the height of Tania's plant at the end of second we will add 0.7 to 2.65.
Therefore, Tania's plant was 3.35 decimeter tall at the end of 2nd week
Answer:
(a) The value of P (X = 2) is 0.3571.
(b) The value of P (X ≤ 1) is 0.5952.
Step-by-step explanation:
A Hypergeometric distribution is used to describe the probability distribution of <em>x</em> successes in <em>n</em> random draws from a population of size <em>N </em>that contains exactly <em>r</em> items that are considered as success. In this distribution each draw results in either a success or a failure.
The probability mass function of Hypergeometric distribution is:
Given:
N = 9
r = 3
n = 4
(a)
Compute the value of P (X = 2) as follows:
Thus, the value of P (X = 2) is 0.3571.
(b)
Compute the value of P (X ≤ 1) as follows:
P (X ≤ 1) = P (X = 0) + P (X = 1)
Thus, the value of P (X ≤ 1) is 0.5952.
Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
9 Should be correct hope that helps
