Answer:
Relatively prime numbers have a GCF of 1. The numbers 38 and 40 have a GCF of 2, so they are not relatively prime.
Step-by-step explanation:
When you say that two numbers are relatively prime, it means that both numbers do not have a common factor except 1. Stephen is incorrect because 38 and 40 are both multiples of 2.
Answer:
Not, 1
Step-by-step explanation:
The complement of an event denoted as A', can be interpreted as not A. This means that elements not belonging to a A. In probabilistic term, if we have an event A, the complement is f A is the probability that event A does not occur.
The sum of an event A and its corresponding complement must equal to 1.
This is given by the complement rule ;
P(A) + P(A') = 1
Hence, P(A') = 1 - P(A)
Probability of drawing a black card is 1/2
Probability of drawing a 9 is 1/13
Multiply together. You get 1/26.
Answer:
The dimensions of the rectangle are: Length: 17 centimeters, Width: 11 centimeters.
Step-by-step explanation:
From Geometry we remember that the perimeter (), measured in centimeters, of a rectangle is determined by the following formula:
(1)
Where:
- Width of the rectangle, measured in centimeters.
- Length of the rectangle, measured in centimeters.
If we know that , and , then the value of is:
And the length and the width of the rectangle are, respectively:
The dimensions of the rectangle are: Length: 17 centimeters, Width: 11 centimeters.
Answer:
x=2*sqrt(5)
Step-by-step explanation:
Since the triangle is isosceles, the other side (not x) is sqrt(10). Using Pythagoras, we have 10+10=x^2, x=2*sqrt(5)
