Answer: A 13.4
Step-by-step
a^2 + b^2= c^2 4^2 + b^2 = 14^2 16+ b^2= 195 b^2= 180 b= square root of 180 b= 6 square root of 5 or 13.42
Answer:
1. Parameter because the value is a numerical measurement describing a characteristic of a population
Step-by-step explanation:
A parameter is a fixed measure which <u>describes the whole population</u> while a statistic is a <u>characteristic of a sample</u> (which is a portion of the target population).
In a study of all 1963 employees at a college, it is found that "40%" own a computer.
The study involved the entire population of employees in the college, therefore the result describes the computer owning <u>characteristics of the whole population under study</u>. It is therefore a parameter.
<u>The correct option is 1.</u>
Answer:
A. A cylinder with diameter 8 units
Step-by-step explanation:
∵ The <u>line</u> m is the <em>central axis</em>
So the radius is 4 units. ∴ Diameter is 8 units.
∵ The picture is a <em>rectangle</em>.
[ The <em>rectangle rotates</em> are its side to form a <em>cylinder</em> ]
So a cylinder with diameter 8 units.
The answer is A.
Answer:
Step-by-step explanation:
Prime factorization: 43 is prime. The exponent of prime number 43 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 43 has exactly 2 factors.
Answer:
218 students purchased tickets at the dance.
Step-by-step explanation:
Let,
x be the number of presale tickets
y be the number of tickets sold at the dance
According to given statement;
x+y=334 Eqn 1
18x+24y=7320 Eqn 2
Multiplying Eqn 1 by 18
18(x+y=334)
18x+18y=6012 Eqn 3
Subtracting Eqn 3 from Eqn 2
(18x+24y)-(18x+18y)=7320-6012
18x+24y-18x-18y=1308
6y=1308
Therefore,
218 students purchased tickets at the dance.
