The answer is 25 to it works because the quotient is greater than 10.
Remember that when dividing by a fraction you gotta flip the second fraction and then multiply.
So -10/1 divided by -2/5 turns into
-10/1 x 5/-2
-50 / -2 = 25

Pea plants contain two genes for seed color, each of which may be Y (for yellow seeds) or G (for green seeds). Plants that contain one of each type of gene are called heterozygous. According to a theory of genetics, if two heterozygous plants are crossed, each of their offspring will have probability 0.75 of having yellow seeds and probability 0.25 of having green seeds.
A) Out of 10 offspring of heterozygous plants, what is the probability that exactly 3 have green seeds?
B) Out of 10 offspring of heterozygous plants, what is the probability that more than 2 have green seeds?
C) Out of 100 offspring of heterozygous plants, what is the probability that more than 30 have green seeds?
D) Out of 100 offspring of heterozygous plants, what is the probability that between 30 and 35 inclusive have green seeds?
E) Out of 100 offspring of heterozygous plants, what is the probability that fewer than 80 have yellow seeds?
Answers
Answer:
a) 0.2503 = 25.03% probability that exactly 3 have green seeds.
b) 0.4744 = 47.44% probability that more than 2 have green seeds.
c) 0.1020 = 10.20% probability that more than 30 have green seeds.
d) 0.1414 = 14.14% probability that between 30 and 35 inclusive have green seeds.
e) 0.8508 = 85.05% probability that fewer than 80 have yellow seeds
Step-by-step explanation:
For questions a and b, the binomial probability distribution is used. For questions c, d and e, the binomial distribution is approximated to the normal.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The expected value of the binomial distribution is:
[tex]E(X) = np[/tex]
The standard deviation of the binomial distribution is:
[tex]\sqrt{V(X)} = \sqrt{np(1-p)}[/tex]
Normal probability distribution
Problems of normally distributed distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
When we are approximating a binomial distribution to a normal one, we have that [tex]\mu = E(X)[/tex], [tex]\sigma = \sqrt{V(X)}[/tex].
A) Out of 10 offspring of heterozygous plants, what is the probability that exactly 3 have green seeds?
10 offspring of heterozygous plants means that [tex]n = 3[/tex]
Probability 0.25 of having green seeds means that [tex]p = 0.25[/tex]
This probability is P(X = 3). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{10,3}.(0.25)^{3}.(0.75)^{7} = 0.2503[/tex]
0.2503 = 25.03% probability that exactly 3 have green seeds.
B) Out of 10 offspring of heterozygous plants, what is the probability that more than 2 have green seeds?
This is
[tex]P(X > 2) = 1 - P(X \leq 2)[/tex]
In which
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]
So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{10,0}.(0.25)^{0}.(0.75)^{10} = 0.0563[/tex]
[tex]P(X = 1) = C_{10,1}.(0.25)^{1}.(0.75)^{9} = 0.1877[/tex]
[tex]P(X = 2) = C_{10,2}.(0.25)^{2}.(0.75)^{8} = 0.2816[/tex]
[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0563 + 0.1877 + 0.2816 = 0.5256[/tex]
[tex]P(X > 2) = 1 - P(X \leq 2) = 1 - 0.5256 = 0.4744[/tex]
0.4744 = 47.44% probability that more than 2 have green seeds.
C) Out of 100 offspring of heterozygous plants, what is the probability that more than 30 have green seeds?
Now
[tex]n = 100[/tex]
[tex]\mu = E(x) = np = 100*0.25 = 25[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{100*0.25*0.75} = 4.33[/tex]
Using continuity correction, this is [tex]P(X > 30 + 0.5) = P(X > 30.5)[/tex], which is 1 subtracted by the pvalue of Z when X = 30.5. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{30.5 - 25}{4.33}[/tex]
[tex]Z = 1.27[/tex]
[tex]Z = 1.27[/tex] has a pvalue of 0.8980
1 - 0.8980 = 0.1020
0.1020 = 10.20% probability that more than 30 have green seeds.
D) Out of 100 offspring of heterozygous plants, what is the probability that between 30 and 35 inclusive have green seeds?
Using continuity correction, this is [tex]P(30-0.5 \leq X \leq 35 + 0.5) = P(29.5 \leq X \leq 35.5)[/tex], which is the pvalue of Z when X = 35.5 subtracted by the pvalue of Z when X = 29.5.
X = 35.5
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{35.5 - 25}{4.33}[/tex]
[tex]Z = 2.42[/tex]
[tex]Z = 2.42[/tex] has a pvalue of 0.9922
X = 29.5
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{29.5 - 25}{4.33}[/tex]
[tex]Z = 1.04[/tex]
[tex]Z = 1.04[/tex] has a pvalue of 0.8508
0.9922 - 0.8508 = 0.1414
0.1414 = 14.14% probability that between 30 and 35 inclusive have green seeds.
E) Out of 100 offspring of heterozygous plants, what is the probability that fewer than 80 have yellow seeds?
0.75 probability of yellow seeds, so [tex]p = 0.75[/tex]. So
[tex]\mu = E(x) = np = 100*0.75 = 75[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{100*0.75*0.25} = 4.33[/tex]
This probability is [tex]P(X < 80 - 0.5) = P(X < 79.5)[/tex], which is the pvalue of Z when X = 79.5.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{79.5 - 75}{4.33}[/tex]
[tex]Z = 1.04[/tex]
[tex]Z = 1.04[/tex] has a pvalue of 0.8508
0.8508 = 85.05% probability that fewer than 80 have yellow seeds

Solve the exponential equations: 2^3x =11
Answers
Answer:
x = 3
Step-by-step explanation:
2 + 3x = 11
3x = 11 - 2
3x = 9 (divide both sides by 3 to get x)
3x/3 = 9/3
x = 3
In the given exponential equations: [tex]2^3x[/tex] = 11, the value of x is [tex]\frac{log_211}{3}[/tex].
Mathematically, an equation is a statement that asserts the equivalency of two expressions. It consists of two hands, the left-hand side( LHS) and the right-hand side( RHS), separated by an equal sign( =). The LHS and RHS can be numbers, variables, constants, or further complex fine expressions.
Equations can be classified based on their degree, which corresponds to the highest power of the variables involved. For example, linear equations have a degree of 1, quadratic equations have a degree of 2, and so on.
Given the equation:
[tex]2^3^x[/tex] = 11
Take the logarithm of both sides,
log [tex]2^3^x[/tex] = log 11
3x log2 = log 11
3x = [tex]\frac{log 11}{log2}[/tex]
3x = [tex]log_211[/tex]
x = [tex]\frac{log_211}{3}[/tex].
So, the value of x is [tex]\frac{log_211}{3}[/tex].

A jewelry store offers its own brand of customizable charm bracelets. You are able to choose from 9
different charms for your bracelet.
How many different charm bracelets is it possible to create?
Answers
Answer:
It depends on the number of charms that your bracelet can have.
here we need to count the number of selections that we have, and the number of options for each one of these selections.
So if we can have only one charm, we have only one selection, and for that selection, we have 9 options, then there are 9 different one-charm bracelets.
If each bracelet can have 2 charms then we have two selections.
For the first selection, we have 9 options,
If each charm can be selected only one time, then for the next selection we will have 8 options, now the total number of combinations is equal to the product between the numbers of options for each selection, so here the total number of combinations is:
C = 9*8 = 72
If we can select 3 charms, then:
first charm = 9 options
second charm = 8 options
third charm = 7 options
Total number of combinations = 9*8*7 = 504 combinations.
Notice that we can not give an exact answer because we do not know the number of charms in each bracelet and we do not know if a charm can be selected multiple times or only one, but here you could see the general way to solve this kind of problems.

Answers
Answer:
(a)
[tex]\%Decrease= 12.5\%[/tex] --- TV
[tex]\%Decrease= 20\%[/tex] --- Laptop
(b) Laptop
Step-by-step explanation:
Given
Normal Sales
[tex]TV = 2000[/tex] [tex]TV = 1750[/tex]
[tex]Laptop = 1800[/tex] [tex]Laptop = 1440[/tex]
Solving (a): Percentage increase of decrease for both
Percentage change is calculated as:
[tex]\%Change = \frac{New - Old}{Old} * 100\%[/tex]
For TV
[tex]\%Change = \frac{1750 - 2000}{2000} * 100\%[/tex]
[tex]\%Change = \frac{-250}{2000} * 100\%[/tex]
[tex]\%Change = -0.125* 100\%[/tex]
[tex]\%Change = -12.5\%[/tex]
It is a decrease because it is negative
[tex]\%Decrease= 12.5\%[/tex]
For Laptop
[tex]\%Change = \frac{1440 - 1800}{1800} * 100\%[/tex]
[tex]\%Change = \frac{-360}{1800} * 100\%[/tex]
[tex]\%Change = -0.2* 100\%[/tex]
[tex]\%Change = -20\%[/tex]
It is a decrease because it is negative
[tex]\%Decrease= 20\%[/tex]
Solving (b):
Laptop has the best reduced price because it has a larger percentage decrease

If a rectangle has length x and width x+3, what is the perimeter of the rectangle in terms of x?
Answers
Answer:
[tex]4x+6[/tex] units
Step-by-step explanation:
Skills needed to solve: Order of Operations, Distributive Property, Perimeter Formula, Like Terms
1) To solve this problem, you need to understand the perimeter formula, and that is:
--> [tex]P = 2(L+W)[/tex]
P = Perimeter
L = Length
W = Width
2) Based on that, we are given that:
[tex]L = x[/tex] (since the length is x)
[tex]W = x+3[/tex] (since the width is x+3)
3) After that, we substitute in the values:
[tex]P = 2(L+W)[/tex]
[tex]P = 2(x+(x+3))[/tex]
[tex]x + (x+3) = x+x+3 = 2x+3[/tex] (with like terms and addition)
so: [tex]P=2(2x+3)[/tex]
Use distributive property, which is [tex]a(b+c) = ab+ac[/tex]
get: [tex]2(2x+3) = 2(2x) + 2(3)[/tex]
[tex]2(2x) = 4x[/tex]
[tex]2(3) = 6[/tex]
So: [tex]P = 4x+6[/tex]
Hope this helps and have a nice day!! :) :]
