Determine whether the statement is true or false. If the statement is false, make the necessary change(s) to produce a true statement.
If an event is certain to occur, its probability is 1.
Answer: false
Step-by-step explanation:
An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
hope this helps
Yes, The statement ''If an event is certain to occur, its probability is 1'' is true.
What is mean by Probability?
The term probability refers to the likelihood of an event occurring.
Given that;
The statement is,
''If an event is certain to occur, its probability is 1.''
Now,
Since, The event that is sure to happen is called a certain event and probability of such an event is 1 as this event is bound to happen.
Thus, The statement ''If an event is certain to occur, its probability is 1'' is true.

I need help finding the volume of the diameter please help ASAP!!!
Answer:
6885.1 yd^3
Step-by-step explanation:
the shape in the attached image is a sphere.
thus, we are to find the volume of a sphere
Volume = 4/3 nr^3
n = 22/7
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
radius = 23.6/2 = 11.8 ft
4/3 x 22/7 x 11,8^3 = 6885.1 yd^3

Solve central angle
Answer:
BC=48 degrees, AD= ??
Step-by-step explanation:
I'm going to find the angle BC so a full circle is 360 degrees but half of a circle is 180 degrees since we are dealing with half a circle its 180, 90 and 42 are already used so lets add these two numbers which is 132 lastly to find out the remaining which is angle BC we have to subtract 180-132 which is 48. So your first answer is 48.
Next is AD which i don't know how to do, Sorry :(

A sales representative sells a salad
dressing recipe for $620 and gets an
additional $0.15 for each bottle sold.
Write an equation to model the total
payment.
Answer:
620+0.15x=total payment
Step-by-step explanation:
It is the price of the recipe plus the amount the representative gets per bottle sold. Replace x with the number of bottles sold and multiply it by the 0.15. Add the 620 and you get your total.
You deposit $4000 in an account earning 4% interest compounded monthly. How much will you
have in the account in 15 years?
You deposit $4000 in an account earning 4% interest compounded monthly. After 15 years, you will have approximately $7224.44 in the account.
To calculate the future value of an account with compound interest, we can use the formula:
Future Value = Principal * (1 + (Interest Rate / Number of Compounding Periods))^(Number of Compounding Periods * Time)
In this case, the principal (initial deposit) is $4000, the interest rate is 4% (or 0.04 as a decimal), and the compounding is done monthly, so there are 12 compounding periods in a year.
Substituting these values into the formula, we have:
Future Value = $4000 * (1 + (0.04 / 12))^(12 * 15)
Calculating this expression gives us:
Future Value ≈ $4000 * (1.003333)^180
Future Value ≈ $4000 * 1.806111
Future Value ≈ $7224.44
After 15 years, you will have approximately $7224.44 in the account, considering the given interest rate and compounding frequency.

find peremiter of pqr
Answer:
79.2 units
Step-by-step explanation:
Tangents to a circle from an external point are congruent , then
PQ = 27.4
QR = 5.9 + 12.2 = 18.1
PR = 12.2 + (27.4 - 5.9 ) = 12.2 + 21.5 = 33.7
Then
perimeter = PQ + QR + PR = 27.4 + 18.1 + 33.7 = 79.2

A. x = 5
B. x = 3
C. x = 6
D. x = 5/2
Answer:
3 ; 5/2
Step-by-step explanation:
Δ= 121 - 120 = 1
x1 = (11 + 1)/4 = 3
x2 = (11-1)/4 =5/2
The solution of the quadratic equation is x = 3 and x = 5/2. Options B and D are correct.
What is a quadratic equation?It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
The given qudratic equation is,
2x² — 11x + 15 = 0
The values of the zeroes of a qudratic equation are calculated by the formula written below,
[tex]x = \dfrac{(-b \pm \sqrt{(b^{2} - 4ac)})} { (2a)}[/tex]
The solution can be calculated as,
[tex]x = \dfrac{(-(-11) \pm \sqrt{((-11)^2 - 4(2)(15))})} {(2(2))}\\x = \dfrac{(11 \pm \sqrt{(121 - 120)})} { 4}\\x = \dfrac{(11 \pm 1)} { 4}[/tex]
Hence, the value of x will be 3 and 5/2 for the given quadratic equation.

PQR is an isosceles triangle with vertex angle Q, PQ = 5x - 24, QR = 3x - 2, and PR = 5x - 8.The length of each leg of △PQR is
Answer:
PQ = 31
QR = 31
PR = 47
Step-by-step explanation:
From the question, we have the vertex as Q
This means that we have the legs as PQ and QR; with PR as the base
The base angles of an isosceles triangle are equal and that means that the leg length values are equal
So, QR = PQ
Thus;
3x-2 = 5x-24
5x-3x = 24-2
2x = 22
x = 22/2
x = 11
So we have PQ as;
5(11) - 24 = 55-24 = 31
QR = 3(11) -2 = 33-2 = 31
PR = 5x-8 = 5(11)-8 = 55-8 = 47

KP is a radius of the circle. Is JK tangent to the circle? Note the figure may not be drawn to scale.
Answer:
JK is NOT tangent to the circle
Step-by-step explanation:
A tangent of a circle is a line that intersects a circle at one and only one point. For this reason, the radius will always intersect a tangent at a 90 degree angle to prove this single point intersection. From the triangle, we can introduce the Pythagorean theorem to see if the triangle is a right triangle:
a^2 + b^2 = c^2
48^2 + 14^2 = 36^2
2304 + 196 = 1296
2500 ≠ 1296
As this is not equal, the triangle is not a right triangle and therefore states that the tangent line does not intersect the radius at 90 degrees, meaning that it does not satisfy the requirements of a tangent line.
