The probability is 102.
What is probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
Moderate Success 0.3 102.0 120 208.0
Failure 0.4 102.0 10.0 100
Now, the probability
E(x) = [tex]\sum^3_i[/tex]= [tex]S_iP_i[/tex]
= 102 x 0.3 + 102 x 0.3 + 102 x 0.4
= 30.6 + 30.6 + 40.8
= 102
Hence, the probability is 102.

The table of ordered pairs (x, y) gives an exponential function.
Write an equation for the function.

48
Answer:
f(x) = 12*(2)^x
Step-by-step explanation:
A generic exponential equation is written as:
f(x) = A*(r)^x
And we also know that this equation passes through:
(-1, 6)
(0, 12)
(1, 24)
(2, 48)
For the second point, (0, 12) we know that when f(0) = 12
Then:
f(0) = 12 = A*(r)^0
And for every real number different than zero, a^0 = 1
Then:
f(0) = A*1 = A = 12
Then the equation is:
f(x) = 12*(r)^x
Now we can use one of the other points, like (1, 24)
Then f(1) = 24
We can solve:
f(1) = 24 = 12*(r)^1 = 12*r
24/12 = r
2 = r
Then the equation is f(x) = 12*(2)^x
Now we need to check if this function also passes through the points (-1, 6) and (2, 24):
f(-1) = 12*(2)^-1 = 12/2 = 6
f(2) = 12*(2)^2 = 12*4 = 48
Nice.
So we can see that the function is f(x) = 12*(2)^x

The length of the piece of ribbon = 3 1/2 yards= 7/2 yards
The length of ribbon required to make a bow = 3/4 yards
Now, the number of bows can be made in the given piece of ribbon = 7/2 divided by 3/4
= 7/2*4/3= 14/3 = 4 2/3
Hence, the number of bows can be made in the given piece of ribbon = 4 2/3

the sum of a number x and 7 is 35
An expression is defined as a set of numbers, variables, and mathematical operations. The value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the statement that the sum of a number x and 7 is 35. Therefore, the given statement "the sum of a number x and 7 is 35" in the form of an expression can be written as,
x + 7 = 35
Subtract 7 from both the sides of the equation,
x +7 - 7 = 35 - 7
x = 28
Hence, the value of x that will satisfy the given statement "the sum of a number x and 7 is 35" is 28.

As a town gets smaller, the population of its high school decreases by 8% each year. The senior class has 320 students now. In how many years will it have about 100
students? Write an equation. Then solve the equation without graphing.
Answer:
in 13.95 years the senior class will have 100 students.
Step-by-step explanation:
P(h) = p(0.92)^t (equation for exponential change)
P(h) - population of highschool (or senior class) = 100
p - staring amount = 320
t = time in years
100 = 320(0.92)^t
1/3.2 = .92^t (divide both sides by 320)
log(1/3.2, .92) = t (log base 0.92 of 1/3.2 equals t)
13.9497 = t

perimeter of this picture frame.
Answer:
6x+2
Step-by-step explanation:
The perimeter is all of the sides added together.
We know that in a rectangle, sides that are parallel to each other are the same.
So, to find the expression that represents the perimeter, you have to multiply 2x+1 by 2 and x by 2 and add both of those together.
(2*(2x+1))+(2*(x))
(4x+2)+(2x)
4x+2+2x

Examine the diagram. A triangle has angles A, 15 degrees, 80 degrees. The exterior angle to angle A is B. What is the sum of the remote interior angles? ° What is the measure of ∠A? m∠A = ° What is the measure of ∠B? m∠B = °
Answer:
m<A = 30degrees
m<B = 70degrees
Step-by-step explanation:
Find the diagram attached
From the diagram;
m<A + 150 = 180
m<A = 180 - 150
m<A = 30degrees
Also since the sum of angles in a triangle is 180degrees, hence;
m<B+m<A + 80 = 180
m<B+30+80 = 180
m<B+110 = 180
m<B = 180 - 110
m<B = 70degrees

Answer:
A = 660.72 in^2 - A = 98 in^2 = 562.7 in^2
Step-by-step explanation:
Formula for a seven sided polygon/heptagon is:
A = (1/4)na^2 cot(π/n) = nr^2 tan(π/n
n n = 7 sides
side length a = 13.4841 in
inradius r = 14 in
circumradius R = 15.5388 in
area A = 660.72 in^2
perimeter P = 94.3886 in
interior angle x = 128.571 °
exterior angle y = 51.4286 °
To calculate the square from a diameter use this formula: q = √(2a^2) = a√2
side length a = 9.8994949366117 in
diagonal q = 14 in
perimeter P = 39.597979746447 in
area A = 98 in^2
