The mean of age is 131.72. Therefore, option C is the correct answer.
Given that, a binomial distribution the experiment consisted of 185 trials in the probability of success and age trial was 0.712.
What is a binomial distribution?The binomial distribution is a commonly used discrete distribution in statistics. The normal distribution as opposed to a binomial distribution is a continuous distribution. The binomial distribution represents the probability for 'x' successes of an experiment in 'n' trials, given a success probability 'p' for each trial at the experiment.
Here, mean= 185×0.712
= 131.72
The mean of age is 131.72. Therefore, option C is the correct answer.

What are rational exponents, and how are they related to integer exponents?
Answer:
See below
Step-by-step explanation:
Integer exponents are a subset of rational exponents
Integer exponents
An integer exponent is an exponent that is an integer. For example, in the expression y = 5³, the 3 is an integer exponent.
An integer exponent is a power. Thus, 5³ = 5× 5× 5.
Rational exponents
Rational exponents can be expressed as a ratio of integers with nonzero denominators.
Thus, in the expression [tex]y = 5^{\frac{ 2}{3 }}[/tex], the fraction ⅔ is a rational exponent.
A rational exponent is both a power and an nth root. The numerator is the power, and the denominator is the root. Thus,
[tex]5^{\frac{ 2}{ 3}} = \sqrt[3]{5^{2}} = (\sqrt[3]{5}})^{2}[/tex]

Chloe is planning her wedding and trying to decide on where to purchase her floral arrangements. At Petals Plus, the arrangements cost $33.04 each, and the store charges $63.00 for delivery of the flowers to the wedding site. At Blooms, the arrangements cost $25.07 each, and the store charges $112.00 for delivery of the flowers to the wedding site.
How many arrangements should she purchase from Blooms in order to get a better value?
A.
6
B.
7
C.
5
D.
1
Chloe should purchase at least 6 arrangements from Blooms to get a better value compared to Petals Plus, as this is the smallest whole number of arrangements where the total cost at Blooms becomes less than that at Petals Plus.
Explanation:To determine how many arrangements Chloe should purchase from Blooms to get a better value, we need to compare the total cost of floral arrangements from both stores for varying quantities. We'll calculate the breaking point where the total cost from Blooms becomes less than that from Petals Plus.
Let the number of arrangements Chloe is considering purchasing be denoted by n. The total cost at Petals Plus for n arrangements would be:
Total cost at Petals Plus = $33.04n + $63.00
Similarly, the total cost at Blooms for n arrangements would be:
Total cost at Blooms = $25.07n + $112.00
Chloe gets a better value from Blooms when the total cost at Blooms is less than at Petals Plus:
$25.07n + $112.00 < $33.04n + $63.00
To find the value of n, we'll solve the inequality:
$8.97n > $49.00
n > $49.00/$8.97
n > 5.46
Since Chloe can't purchase a fraction of an arrangement, the smallest whole number of arrangements she should purchase from Blooms to get the better value is 6. Therefore, the answer is option A: 6.
formala to calculate time for exponential growth
Answer:
To calculate exponential growth, use the formula y(t) = a__ekt, where a is the value at the start, k is the rate of growth or decay, t is time and y(t) is the population's value at time t.
Mark as brainliest please..
To calculate the time for exponential growth, use the formula n = ln(M) / ln(b) for a specific multiple (M) and growth rate (b), or the Rule of 70 for estimating doubling time.
Explanation:Understanding Exponential Growth
The formula to calculate the time for exponential growth depends on the growth rate and the factor by which a quantity increases. If the growth rate is constant and represented as a percentage or fraction, the growth is exponential. For example, if a bacterial population doubles every hour, starting with 1000 bacteria, it will grow to 2000 after one hour, 4000 after two hours, and so on.
Calculating Time for Exponential Growth
One formula to find the time (n) to reach a certain multiple (M) of the original amount at a specific growth rate (b) is:
n = ln(M) / ln(b)
For instance, to calculate the time to increase by a factor of 1000 with an annual growth rate of 7% (b = 1.07):
n = ln(1000) / ln(1.07) ≈ 102 years
This equation shows that it would take approximately 102 years for the quantity to grow by a factor of 1000.
The Rule of 70
t = 70 / growth rate
t = 70 / 2.9 ≈ 24 years
The time it takes for exponential growth can vary significantly based on the growth rate and the factor of increase desired.

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2
C
The prism is filled with cubes that have edge lengths of 1/2 cm
How many cubes are needed to fill the rectangular prism?
Answer:
Step-by-step explanation:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes
Answer:
The number of cubes are needed to fill the rectangular prism = 448 cubes
Step-by-step explanation:
It is given that,
A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2 cm. The prism is filled with cubes that have edge lengths of 1/2 cm
To find the volume of rectangular prism
Volume of rectangular prism = Length x Width X Height
Length = 7 cm, Width = 4 cm and height = 2cm
Volume = 7 x 4 x 2 = 56 cm³
To find the volume of small cubes
Volume of cube = a³
a = 1/2 cm = 0.5³ = 0.125
To find the number of cubes needed to fill prism
Number of cubes = Volume of prism/ volume of cube
= 56/0.125 = 448 cubes
Therefore the correct answer is 448 cubes

Please help need answer
Answer:
Step-by-step explanation:
First, let's look at the pie-shaped segment defined by the 123° angle and the 18.6 m radius.
The area of the entire circle is given by A = πr² = 3.14159(18.6 m)², or A = 1086.865 m².
The area of the "pie slice" is (123/360) of that, or 371.346 m².
Next, we must find the area of the triangle and subtract this area from this 371.346 m²:
Use the Law of Cosines to find the area of this triangle. The Law of Cosines in appropriate form is
c² = a² + b² -2ab*cos C.
In this case C is 123° and a and b are both 18.6 m in length. Thus,
c² = (18.6 m)² + (18.6 m)² - 2(18.6 m)(18.6 m)*cos 123°
Thus,
c² = 691.92 m² - 691.92*cos 123°, or
= (691.92 m²)(1 - cos 123°)
= (691.92 m²)(1 - [-0.5446] ) = (691.92 m²)(1.5446) = 1068.767
Taking the square root of this result, we get c = +32.6920 m.
Subdivide the triangle shown to form a new triangle with hypotenuse 18.6 m, adjacent side 32.6920 m / 2, or 16.3460 and opposite side h.
Then 18.6² = h² + 16.3460², which leads to h²2 = 18.6² - 16.346², or 78.768.
Then h = √78.768 = 8.875 (m).
We now use this info to find the area of the illustrated triangle, using the formula A = (1/2)(base)(height). That comes out to:
A = (1/2)(16.3460 m)(8.875 m) = 72.535 m²
Finally, we subtract twice that from the area of the 'pie' to get the area of the yellow (shaded) area:
pie area - area of triangle shown in the diagram =
371.346 m² - 145.071 m² = 226.3 m² (to the nearest tenth)

Which probability distribution table corresponds with this frequency distribution table?
Answer:
Table 2
Step-by-step explanation:
The given frequency distribution table is
X : 1 2 3 4 5
f : 11 1 2 4 2
The sum of frequencies is
[tex]\sum f=11+1+2+4+2=20[/tex]
The formula for probability is
[tex]P_i=\frac{f_i}{\sum f}[/tex]
where, [tex]f_i[/tex] is frequency and [tex]\sum f[/tex] in the sum of frequencies.
For X=1,
[tex]P_1=\frac{11}{20}=0.55[/tex]
For X=2,
[tex]P_2=\frac{1}{20}=0.05[/tex]
For X=3,
[tex]P_3=\frac{2}{20}=0.1[/tex]
For X=4,
[tex]P_4=\frac{4}{20}=0.2[/tex]
For X=5,
[tex]P_5=\frac{2}{20}=0.1[/tex]
The probability distribution table corresponds with the given frequency distribution table is
X : 1 2 3 4 5
P : 0.55 0.05 0.1 0.2 0.1
Therefore, the correct option is 2.
The only probability distribution table that corresponds with the frequency distribution table is; Second table
From the given frequency distribution table, let's find the sum of the given frequencies. Thus;
Σf = 11 + 1 + 2 + 4 + 2
Σf = 20
Now,the probability for each value of x will be;
P_x = f_x/Σf
Where f_x represents the frequency of the given value of x.
Thus;
P_1 = 11/20
P_1 = 0.55
P_2 = 1/20
P_2 = 0.05
P_3 = 2/20
P_3 = 0.1
P_4 = 4/20
P_4 = 0.2
P_5 = 2/20
P_5 = 0.1
Looking at the tables in the options, in conclusion the only tables that have their P value corresponding with those we got for each value of x is Option B which is the second table.
