Given:
⇒ Probability of happening of an event = 45%
To Find:
⇒ Probability of event
Now, probability of happening of an event is 45% means non happening event is 100 - 45 = 55%.
⇒ Probability of happening event = 45/100
⇒ Probability of happening event = 0.45
⇒ Probability of non happening event = 55/100
⇒ Probability of non happening event = 0.55
Hence, the correct option is (c) 0.45.
Extra Info:
Probability is the likelihood /chances of a given event's occurence which is expressed as a number between 1 and 0.

—
Two-fifths of nine is a number.
Two-fifths of a number is nine.
Nine more than two-fifths of a number is nine.
A number plus nine is the same as two-fifths of nine.
Answer:
Nine more than two-fifths of a number is nine.
Step-by-step explanation:
we know that the total will be 9, and that 2/5x is equivalent to 2/5 of a number (so it should be 2/5n) and we are adding 9 more.
Traveling at a speed of 12 mph, Jen biked home in 20 minutes. What was Jim's speed
if he biked the same distance in 15 minutes?
The speed of Jim if he biked the same distance in 15 minutes is 16 mph
What is speed ?Speed is the distance covered at a particular time. Therefore,
speed = distance / time
The distance in the first journey can be calculated as follows:
speed = 12 mph
time = 20 minutes = 0.3333 hours
12 = x / 0.333
distance = 0.333 × 12 = 3.9996 miles
Therefore, the speed of Jim if he biked the same distance in 15 minutes can be calculated as follows:
15 minutes = 0.25 hours
speed = 3.9996 / 0.25
speed = 15.9984
speed = 16 mph

The speed of Jim if he biked the same distance faster than Jen. In 15 minutes is 16 mph is Jim’s speed
Step-by-step explanation:
center and the radius please!
Answer:
the center is (-2,4) and the raduis is 3
Step-by-step explanation:
For equations of circles, the center will be the inverse of the euation. for example. If the equation had (x+3)^2 and (x-4)^2 the center is (-3,4).
And for the raduis of a circle equation it is always r^2. Since the 9 is in place, 3^2 is just 3x3 = 9.

An airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pounds. The inequality represents the amount of weight Lorrie can add to the carry-on without going over the 30-pound limit.
21.2 + w less-than-or-equal-to 30
How much weight can Lorrie add to the carry-on without going over the 30-pound limit?
Answer: No more than 8.8 pounds.
Step-by-step explanation: Let x be the weight that Lorrie can add to carry-on.
We are told that an airline charges an extra fee if a carry-on bag weighs more than 30 pounds. After packing, Lorrie’s carry-on weighs 21.2 pounds. The inequality that will represent the the amount of weight Lorrie can add to the carry-on without going over the 30-pound limit is:
Let us solve for x by subtracting 21.2 from both sides of our inequality.
We can see that the weight Lorrie can add to the carry-on should be less than or equal to 8.8 pounds without going over the 30 pound limit. Therefore, the weight that Lorrie can add to the carry-on should be no more than 8.8 pounds.

Describe how to use the formula C = StartFraction 5 Over 9 EndFraction (F minus 32) to find the temperature in degrees Celsius if the temperature is 86°F. What is the temperature in degrees Celsius?
WRITEN RESPONE
Answer:
30°C
Step-by-step explanation:
The Conversion Formula :-
F - 32 / 9 = C / 5F is given to be 86.
Substitution
86 - 32 / 9 = C / 554 / 9 = C / 5C = 6 x 5C = 30°CAnswer:
Sample Response: To find the celsius temperature, substitute 86 for F in the formula. Then, use the order of operations to simplify. Substract 32 from 86. Then multiply 5 9 by 54 to get 30°C.

Step-by-step explanation:
the slope intercept form is
y = ax + b
"a" being the slope, "b" being the y- intercept (which is the y-value when x = 0).
the slope here :
in the table x is always increasing by 2.
and y is always investing by 1.
so, the slope is 1/2
the y-intercept :
we need to find the y-value for x = 0.
but we don't have a data point with x = 0 in the table.
so, we have to extend the structure of the table to the left.
x decreases by 2 (making it 0), and y decreases by 1 (making it -1).
therefore, the y- intercept (b) is -1.
and the line equation is
y = (1/2)x - 1
not sure about "the other method".
there is the point-slope form of the equation :
y - y1 = a(x - x1)
again with "a" begin the slope, and (x1, y1) being a point on the line.
if we get the y-intercept in the table, then this point is (0, y1).
and the equation would be
y - y1 = ax
in our case
y + 1 = (1/2)x
and another method ?
sometimes people write
nx + my = c
in our case starting with the original equation
y = (1/2)x - 1
2y = x - 2
-x + 2y = -2
x - 2y = 2

Two sides of an isosceles triangle have lengths 12 and 18. What
is the greatest possible value of the perimeter of the triangle?
Please help me.
The greatest possible value of the perimeter of the triangle is 48
What is the perimeter of a triangle?The perimeter of a triangle is the sum of the lengths of the three sides of the triangle.
An isosceles triangle has 2 equal sides and the length of the 2 sides must be greater than the length of one.
Perimeter A= 12×2+18=42
Perimeter B= 12+18×2=48
Therefore the greatest possible perimeter of the triangle is Perimeter B (48) since the sum of lengths of the two equal sides(18) is greater than the third side (12) and 48 is greater than 42.

A triangle has two side lengths: 18 in and 12 in. Which of the following could be the length of the third side?
Answer:
6<L<30
Step-by-step explanation:
because we know that the third side needs to be in between the sum of the other two it has to be less than 30 and then because it needs to apply to the other sides it is greater then 18-12 or 6.

Wanda spun a spinner 30 times, and the results were recorded in the following tally chart
Answer:
30%
Step-by-step explanation:
So she spun the spinner 30 times so we divide the number of times she got solid by the 30 to get the answer in a percentage :)
9/30 = 0.3
Now we multiply the 0.3 by 100 to get it as a percent!
0.3 x 100 = 30%
Now you know how to find the probability of an object!
Have a great day!!
Please rate and mark brainliest!!
Explanation:
Count the tally marks for the "solid" in the middle row. The first portion is a group of 5 as shown by the slash mark. The second portion of that row is one short of five, so it's another 4 tallies. Overall, we have 5+4 = 9 tallies for the "solid".
This is out of 30 spins total. Therefore, we arrive at 9/30 = (3*3)/(3*10) = 3/10
HELP!!! The diameter of a circular wall hanging is 4 ft. What is the area of the wall hanging to the nearest tenth? Use 3.14 for π.
A: 3.1 ft2
B: 12.6 ft2
C: 9.4 ft2
D: 6.3 ft2
Help it’s do in 5 minutes
Answer:
B
Step-by-step explanation:
Area of circle= πr²
Start by finding the radius:
Diameter= 2(radius)
4= 2(radius)
radius= 4 ÷2
radius= 2 ft
Area of circular wall hanging
= 3.14(2²)
= 3.14(4)
= 12.56
= 12.6 ft² (nearest tenth)

Ramer and knox began a partnership by investing $64,000 and $94,000, respectively. the partners agreed to share net income and loss by giving annual salary allowances of $52,000 to ramer and $41,600 to knox, 10% interest allowances on their investments, and any remaining balance shared equally. (enter all allowances as positive values. enter losses as negative values.) required: 1. determine each partner's share given a first-year net income of $102,800. 2. determine each partner's share given a first-year net loss of $20,800.
Each partner's share given a first-year net income of $102,800 is $-3,300.
Each partner's share given a first-year net loss of $20,800 is $-44,300.
What is each partner's share?Partner' share = net income / loss - interest - salary salary allowance
Interest = ($64000 x 10%) + ($94000x 10%) = $15,800
Salary = $52,000 + $41,600 = $93,600
Share of net income = [$102,800 - (15,800 + 93600)] / 2 = $-3,300
Share of net loss = [-20,800 - (15,800 + 93600)] / 2 = $-44,300

Mary wants to buy a sewing machine, she can buy it for $315 cash, or on hire purchase for $25 down payment and 12 monthly instalments of $27. 50. How much more will Mary have to pay on hire purchase?
Answer:
She will pay $40 more.
Step-by-step explanation:
I used the equation y=27.50x + 25 to find this out and made x = 12 to represent how many months she is paying.
now putting x into the equation, y = 27.50(12) + 25
First i did the multiplication, 27.50 x 12 = $330.
Then I added 25 to 330 for the down payment, 330 + 25 = 355
I then did 355 - 315 to find out how much more you would pay,
355 - 315 = $40
