What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that on a sample of 400 people, 22% owned cats
Let consider that the number of cats are p then we have;
22% of 400 = p
Thus, p = 400 x 22/100
p = 4 x 22
p = 88 people
The p value is 88

A basketball player has a 25% accuracy rate at making three-point shots. Mark thought it was reasonable that each attempt was independent and the probability stayed at 25% for this player. P (X equals k )equals (1 minus p )to the power of k minus 1 end exponent p Using the geometric distribution formula, what is the probability that the basketball player makes his first three-point shot on the third attempt
The probability that the basketball player makes his first three-point shot on the third attempt is 0.38.
What is geometric distribution?A discrete probability distribution known as a geometric distribution may be used to describe the likelihood of experiencing success for the first time following a string of failures. Up until the first success, a geometric distribution can undergo an infinite number of trials.
The number of separate trials necessary to achieve success is described by the geometric distribution,
which is a probability distribution.
In this scenario, the basketball player's three-point accuracy rate is 25%, which indicates that the probabilities of success (hitting a three-point shot) and failure (missing a three-point shot) are 0.25 and 1-p, respectively.
The likelihood that the basketball player will make his first three-point shot on the third try,
according to the geometric distribution formula, is:
P(x = 3) = (1-p)⁽³⁻¹⁾ × p
= (0.75)² × 0.25
= 0.38
Hence, there is a 38% probability that the basketball player will make his first three-point shot on the third attempt.

Answer:
C) 41
Step-by-step explanation:
The angles of the linear pair are supplementary, so you have ...
(x +16)° +123° = 180°
x = 41 . . . . . . . . . . . . . . divide by °, subtract 139
Answer:
x = 41
Step-by-step explanation:
The angles shown are supplementary
Supplementary angles add up to equal 180
This means that x + 16 + 123 = 180
x + 16 + 123 = 180
Solve for x
Combine like terms ( add 16 and 123 )
x + 139 = 180
Subtract 139 from both sides
x = 41

Find the perimeter of the shape shown below.
Answer:
22 cubes
Step-by-step explanation:
Hi! I'm happy to help!
Perimeter is the total length of all the sides.
Let's start out with the top left corner and work our way counterclockwise.
For our first segment, we start from the top left corner and go to the bottom left corner, this is a length of 3, let's start our equation:
3+
Next, we are at the bottom left corner, let's go to the bottom right corner. This is a length of 5. Let's expand our equation:
3+5+
Now we are at the bottom right corner, let's go to the top right corner. This is also a length of 3. Let's add that to our equation:
3+5+3+
Now we are at the top right corner, lets go to the top middle right corner, which is to the left one unit. Let's add this:
3+5+3+1+
Now, let's head down 2 units to the inside of our shape.
3+5+3+1+2+
Move toward the center one unit:
3+5+3+1+2+1+
Move up one unit:
3+5+3+1+2+1+1+
Move left one unit:
3+5+3+1+2+1+1+1+
Move down one unit:
3+5+3+1+2+1+1+1+1+
Move left another unit:
3+5+3+1+2+1+1+1+1+1+
Start heading back up 2 units towards the top left corner:
3+5+3+1+2+1+1+1+1+1+2+
Finally, reach back 1 unit to the top left corner:
3+5+3+1+2+1+1+1+1+1+2+1=
Let's solve:
3+5+3+1+2+1+1+1+1+1+2+1=
8+3+1+2+1+1+1+1+1+2+1=
11+1+2+1+1+1+1+1+2+1=
12+2+1+1+1+1+1+2+1=
14+1+1+1+1+1+2+1=

16+1+1+1+2+1=
17+1+1+2+1=
18+1+2+1=
19+2+1=

The velocity, V, of a specific object being dropped from a particular height, h, can be found by the radical function V = sqrt 2ha. Where A represents the acceleration in ft/sec2. If the acceleration due to gravity is 32.2 ft/sec2, at what height should you drop an object in order for it to have a velocity of 60 ft/sec?
0.9 feet
55.6 feet
55.9 feet
3,864 feet
Answer:
55.9 feet
Step-by-step explanation:
Basically you can just plug in what they give you
givens:
V=60 ft/sec
a= 32.2 ft/sec^2
function to find velocity: [tex]V=\sqrt{2ha[/tex]
if you plug everything in: [tex]60=\sqrt{2(h)(32.2)[/tex]
you can just put that equation into a website and ask it to solve for h which would give you your answer
but, if you want the work,
FIRST square both sides of the equation to get rid of the square root symbol on the left so,
[tex]60^{2} =\sqrt{2(t)(32.2)} ^{2}[/tex]
which cancels out to
[tex]3600= 2(t)(32.2)[/tex]
NEXT: divide both sides by 32.2 to get 2t by its self so,
[tex]\frac{3600}{32.2} =\frac{2(t)(32.2)}{32.2}[/tex]
which should get you to
[tex]111.80124223=2(t)[/tex]
LAST: divide both sides by 2 to get t by itself so
[tex]\frac{111.80124223}{2} =\frac{2(t)}{2}[/tex]
and you should end up with
55.900621 = t
which rounded would be an answer of
t= 55.9 feet

Cost per notebook * number of students
35 * 34 = 1190
35*30=1050
35*4 = 140
35*34 = 1050 + 140 = 1190
