there are 5 major sea islands in the queen elizabeth islands of canada that you are interested in visiting. there are 12 major lakes in saskatchewan, canada that you would also like to visit. (a) if you are planning a trip to visit one of these islands, followed by one of these lakes, how many different trips could you make?
The person can make 60 trips.
Let us say that A indicates the major sea Islands and B indicates the major lakes. Taking both the cases as events, we will use multiplication principle. Based on the information, the event A occurs in m ways and the event B will occur in n ways. So, the two events will occur in m×n ways.
Thus, A × B = 5 × 12
Performing multiplication on Right Hand Side of the equation to find the number of trips
Total number of trips = 60
Hence, there are 60 trips that could be made.

in a class of 150 students the ratio of boys to girls is 3 2 how many more boys than girls are in the class
The number of boys and girls in a class of 150 students is 90 and 60 respectively.
RATIO:
Comparing two quantities of the same units and determining the ratio tells us how much of one quantity is in the other.
i.e., it shows how many times a number contains another.
Total number of students = 150
ratio of boys to girls = 3 : 2
B:G = 3 : 2
now
3x + 2x = 150
5x = 150
x = 30
the number of boys = 3x = 3 X 30 = 90 boys.
the number of girls = 2x = 2 X 30 = 60 girls.

if 3200 yards was used for fencing, then 3200 yards is perimeter
and perimeter of a rectangle = 2( L + B)
so that,
2(L + B) = 3200
L + B = 1600
express L in terms of B
L = 1600 - B
Area(A) = L X B
A = L X B
substitute L = 1600 -B
A = (1600 - B) x B
multiply out
A = 1600B - [tex]B^{2}[/tex]
for maximum area,
[tex]\frac{dA}{dB}[/tex] = 0
But dA / dB = 1600 - 2B
1600 - 2B = 0
2B =1600
B = 1600/2
B = 800 yards
L = 1600 - B
L = 1600 - 800
L = 800 yards
Area = L X B
A = 800 x 800

Are the events “blonde hair” and “brown eyes” independent?
The events “blonde hair” and “brown eyes” are not independent.
What are independent events?
The term "independent events" refers to those whose occurrence is not reliant on another event.
When two events A and B are independent then the intersection of the two events is equal to zero. i.e. They do not have any element in common.
But from the given table we can see that the intersection of the events of "blonde hair" and "brown eyes" exists.

simplify (3^6)^5/9x3^7 give your answer as an power of 3
We are going to use these properties :
1. (a^m)^n = a^mn
2. a^m x a^n = a^(m+n)
3. a^m : a^n = a^(m-n)
Using the first property, (3^6)^5 = 3^(6x5) = 3^30
Using the second property :
9 = 3^2
-> 9 x 3^7 = 3^2 x 3^7 = 3^(2+7) = 3^9
Therefore, it is simplified down to 3^30 : 3^9
Finally, we will use the third property :
3^30 : 3^9 = 3^(30-9) = 3^21

Triangle FGH has vertices F(-3, 4), G(2, 0), and H(-1, -2). Graph AFGH and its image after a rotation of 180° about (-3, -6).
Answer:
Im gonna assume its counter clockwise (excuse the bad drawing)
Step-by-step explanation:
The vertices of triangle F'G'H' after a rotation of 180° about (-3, -6) are F'(0, 10), G'(5, 6) and H'(2, 4).
What is rotation?Rotations are transformations that turn a shape around a fixed point. To rotate a shape we need: a centre of rotation. an angle of rotation (given in degrees) a direction of rotation – either clockwise or anti-clockwise.
Given that, triangle FGH has vertices F(-3, 4), G(2, 0), and H(-1, -2).
180° clockwise and counterclockwise rotation: (x, y) becomes (-x,-y).
So, (x, y) → (x+3, y+6)
F(-3, 4) → (-3+3, 4+6) → F'(0, 10)
G(2, 0) → (2+3, 0+6) → G'(5, 6)
H(-1, -2) → (-1+3, -2+6) → H'(2, 4)
Therefore, the vertices of triangle F'G'H' after a rotation of 180° about (-3, -6) are F'(0, 10), G'(5, 6) and H'(2, 4).

The simplified expression of the radical expression given as 5√7/√35 is 7
How to evaluate the expression?From the question, we have the following expression that can be used in our computation:
5√7/√35
The above expression is a fraction and at the same time it is a radical expression
The denominator of the fraction is √35
So, we start by rationalizing the expression by the fraction
This is represented as
5√7/√35 = 5√7/√35 * √35/√35
Evaluate the products of the numerator
So, we have the following representation
5√7/√35 = 5√245/√35 * 1/√35
Evaluate the products of the denominator
So, we have the following representation
5√7/√35 = 5√245/35
Simplify the fraction
This gives
5√7/√35 = √245/7
Simplify the fraction
5√7/√35 = 7√5/7
So, we have
5√7/√35 = 7
Hence, the simplified expression is 7

The series expansion for e z 1 z up to z 5 is obtained by multiplying the Maclaurin series for e z and 1 1 z. For |z| 1, this series converges.
The Maclaurin series for e^z is:
e^z = 1 + z + z^2/2! + z^3/3! + z^4/4! + ...
The Maclaurin series for 1/1-z is:
1/(1-z) = 1 + z + z^2 + z^3 + z^4 + ...

One leg of a right triangle is 7 units long, and its hypotenuse is 16 units long. What is the length of the other leg? Round to the nearest whole number.
Answer:
7^{2} + x^{2} = 16^{2}
49+x^2=256
x^2=207
x=14.387=14
Answer:
14 units
Step-by-step explanation:
To find the length of the other leg of a right triangle, where one leg is 7 units long and the hypotenuse is 16 units long, use Pythagoras Theorem.
Pythagoras Theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the legs.
Let the legs of the right triangle be "a" and "b", and the hypotenuse be "c". Therefore:
[tex]\begin{aligned}a^2+b^2&=c^2\\a^2+7^2&=16^2\\a^2+49&=256\\a^2+49-49&=256-49\\a^2&=207\\\sqrt{a^2}&=\sqrt{207}\\a&=14.3874945...\\a&=14\;\sf(nearest\;whole\;number)\end{aligned}[/tex]
Therefore, the length of the other leg is 14 units (rounded to the nearest whole number).

a passenger train traveled 240 miles in the same amount of time it took a freight train to travel miles. the rate of the freight train was miles per hour slower than the rate of the passenger train. find the rate of the passenger train.
The rate of the passenger train is 60mph.
We know that,
Speed = Distance / Time
Time = Distance / Speed
s = speed of passenger train
speed of freight train = (s - 20)
T = 240 / s
T = 160 / (s-20)
240 / s = 160 / (s-20)
240(s - 20)/s(s - 20) = 160s/s(s - 20)
240(s - 20)/s(s - 20) - 160s/s(s - 20) = 0
240(s - 20) - 160s = 0s(s - 20)
240s - 4800 - 160s = 0
80s - 4800 = 0
