Step-by-step explanation:
Using the geometric distribution function, we get:
P( 3 ) = (1 -p)2*p = (1 - 0.8)2*0.8 = 0.032
Therefore 0.03200 is the required probability here.
What are probability and example?Probability= the number of methods of accomplishing achievement. the total number of possible consequences. as an example, the chance of flipping a coin and its being head is ½, due to the fact there's 1 manner of having a head and the overall variety of viable effects is two (a head or tail).
Probability is definitely how likely something is to show up. every time we are uncertain approximately the outcome of an occasion, we will talk about the probabilities of sure effects—how possibly they are. The evaluation of events governed with the aid of probability is referred to as records.

Write a^4 - 3a^2 + 9 as a product of two monic quadratics with integer coefficients. I got (a^2 + a + 3)(a^2 - a + 3), but it says its wrong.
The correct factorization would be equal to [tex](a^2 - 3)(a^2 - 3)[/tex].
To express the expression [tex]a^4 - 3a^2 + 9[/tex] as a product of two monic quadratics with integer coefficients, we can start by factoring it using the difference of squares formula. Let's break it down step by step:
[tex]a^4 - 3a^2 + 9[/tex]
We can rewrite the expression as:
[tex](a^2)^2 - 3(a^2) + 3^2[/tex]
Now, the difference of squares formula:
[tex](a^2 - 3)^2[/tex]
So, the expression can be factored as the square of the binomial [tex](a^2 - 3)[/tex].
Therefore, the correct factorization is [tex](a^2 - 3)(a^2 - 3)[/tex].

The Kansas predicted that in 2018 the population in Centerville would be 17,466 and actuality it was 16,400 what is the percent error
Answer:
6.5%
Step-by-step explanation:
Percentage error formula =
|Estimated value - Real value|/Real value × 100
From the above question,
Estimated value = 17,466
Real value = 16,400
Percentage error = |17,466 - 16,400|/16,400 × 100
= 1066/16,400 × 100
= 0.065 × 100
= 6.5%
Therefore, the percent error = 6.5%
Answer: 6.5%
Step-by-step explanation: 17,466 - 16,400 = 1,066 (the difference)
16,400 / 16,400 = 1 • 100 = 100
1,066 / 16,400 = 0.065 • 100 = 6.5

Juan and Ari went to the farmers market to buy fruit. Juan’s bag of apples that he bought weighed 31/7 pounds. Ari’s bag of oranges that she bought weighed 19/3 pounds. Using compatible fractions, estimate how much heavier Ari's bag is compared to Juan's bag.
A) 1 and one-half pounds
B) 2 pounds
C) 6 pounds
D) 10 and one-half pounds
Answer:
B: approximately 2 pounds
Step-by-step explanation:
Juan’s bag weighed 31/7 pounds
Ari's bag weighed 19/3 pounds.
We are told to use compatible fractions to determine the difference. Thus we have to make sure the denominator is the same;
For Juan, let's multiply both numerator and denominator by 3 to get; 93/21 pounds
For Ari, let's multiply both numerator and denominator by 7 to get; 133/21
Thus, difference is;
(133/21) - (93/21) = 40/21
This gives;
1.9 pounds heavier
This is approximately 2 pounds
Answer:
B. 2 pounds

Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(x₁, y₁)(x₂, y₂)Using the formula to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function
Slope = m = [y₂ - y₁] / [x₂ - x₁]
For example, let the points be
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 4)
Determining the slope between
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 1]
= 2 / 2
= 1
Thus,
The slope of the line between the points (1, 2) and (3, 4) will be: m = 1
Write as a product: 25a2−0.01b10
Answer:
We conclude that:
[tex]25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex]
Step-by-step explanation:
Given the expression
[tex]25a^2-0.01b^{10}[/tex]
Rewrite [tex]25a^2-0.01b^{10}[/tex] as [tex]\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2[/tex]
so
[tex]25a^2-0.01b^{10}=\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2[/tex]
Apply difference of two squares formulas:
[tex]x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]
so
[tex]\left(5a\right)^2-\left(\sqrt{0.01}b^5\right)^2=\left(5a+\sqrt{0.01}b^5\right)\left(5a-\sqrt{0.01}b^5\right)[/tex]
[tex]=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex] ∵ [tex]\sqrt{0.01}=0.1[/tex],
Therefore, we conclude that:
[tex]25a^2-0.01b^{10}=\left(5a+0.1b^5\right)\left(5a-0.1b^5\right)[/tex]

Find the value of x, giving reasons for your answer:
Answer:
x = 55
Step-by-step explanation:
[tex](x + 40) \degree = (150 - x) \degree \\ (vertical \: \angle s) \\ \\ x + 40 = 150 - x \\ \\ x + x = 150 - 40 \\ \\ 2x = 110 \\ \\ x = \frac{110}{2} \\ \\ x = 55[/tex]
Answer:
x = 55°
Step-by-step explanation:
When any 2 lines intersect each other at one point , the vertically opposite angles are always equal. Hence ,
[tex]150 - x = x + 40[/tex]
[tex] = > x + x = 150 - 40[/tex]
[tex] = > 2x = 110[/tex]
[tex] = > x = \frac{110}{2} = 55[/tex]

A survey found that 31 of 60 randomly selected women and 38 of 73 randomly selected men follow a regular exercise program. Find a 95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program.
Answer:
95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program
(-0.1740 , 0.1672)
Step-by-step explanation:
Step(i):-
Given A survey found that 31 of 60 randomly selected women
First sample proportion
[tex]p_{1} = \frac{x_{1} }{n_{1} } = \frac{31}{60} = 0.5166[/tex]
Second sample proportion
[tex]p_{2} = \frac{x_{2} }{n_{2} } = \frac{38}{73} = 0.520[/tex]
Level of significance = 0.05
Z₀.₀₅ = 1.96
Step(ii):-
95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program
[tex]((p_{1} ^{-}-p^{-} _{2} - Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ), (p_{1} ^{-}-p^{-} _{2} +Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ))[/tex]
where
[tex]Se(p_{1} - p_{2} ) = \sqrt{\frac{p_{1} (1-p_{1} )}{n_{1} }+\frac{p_{2}(1-p_{2} }{n_{2} } }[/tex]
[tex]Se(p_{1} - p_{2} ) = \sqrt{\frac{0.5166 (1-0.5166 )}{60 }+\frac{0.520(1-0.520 }{73 } } = 0.08706[/tex]
95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program
[tex]((p_{1} ^{-}-p^{-} _{2} - Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ), (p_{1} ^{-}-p^{-} _{2} +Z_{0.05} S.E(p_{1} ^{-} - p^{-} _{2} ))[/tex]
((0.5166-0.520-1.96(0.08706) , 0.5166-0.520+1.96(0.08706))
(-0.1740 , 0.1672)
Final answer:-
95% confidence interval for the difference between the proportions of women and men who follow a regular exercise program
(-0.1740 , 0.1672)

Including Jose, there are eight people in his family. If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
Answer:
840 ways
Step-by-step explanation:
From the above question, we are told that order matters, hence, to solve the above question, we use the Permutation formula.
P(n, r) = nPr = n!/(n -r)!
From the above question,
Since Jose is included in the 8 people and he takes the first seat
n = 8 - 1 = 7 people
r = 5 - 1 = 4 seats
This is because, once Jose takes the first seat, there are 4 seats left with 7 people waiting to be seated
Hence,
7P4 = 7!/(7 - 4)!
7P4 = 7!/3!
7P4 = 5040/6
7P4 = 840 ways

840
