Answer:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]
Step-by-step explanation:
Rational Numbers
The rational numbers are defined as numbers of the form [tex]\frac{a}{b}[/tex] where a and b are integer numbers and b is not zero.
Two rational numbers expressed as fractions can be better compared if they have the same denominator. For example, 5/11 is greater than 3/11 because they have the same denominator and 5 is greater than 3.
Similarly, if we have the fractions -5/13 and 1/13, it's clear that the first fraction is less than the second. If we wanted to have some rational numbers between them we only have to play around with the numerators: any number between -5 and 1 will do.
Examples of the required numbers:
[tex]\displaystyle -\frac{4}{13},~-\frac{3}{13},~-\frac{1}{13},~0[/tex]
Suppose a population grows according to a logistic model with initial population 1000 and carrying capacity 10,000. If the population grows to 2500 after one year, what will the population be after another three years?
Answer:
7500
Step-by-step explanation:
1 year= 2500
3 years= x
So we got
2500 × 3 = 7500
The population after another three years will be 15,625.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
Assume a populace becomes as per a strategic model with starting populace of 1,000 and conveying limit of 10,000.
If the population grows to 2500 after one year. Then the increasing factor is given as,
b = 2,500 / 1,000
b = 2.5
Then the equation is given as,
y = 1,000 × (2.5)ˣ
Then the population after another three years will be given as,
y = 1,000 × (2.5)³
y = 1,000 × 15.625
y = 15,625
The population after another three years will be 15,625.

Answer:
The answer is B.
Step-by-step explanation:
4 is a multiple of 2, which explains the reasoning of answer choice B.
Answer choice A is wrong because 2 is Not a multiple of 4.
Answer choices C and D are incorrect because it takes multiple steps to solve for x and substitute into the other equation. They claim that it takes on step to solve for x, but it would take 2 steps to solve for x.

Connor works in a department store selling clothing. He makes a guaranteed salary of $300 per week, but is paid a commission on top of his base salary equal to 5% of his total sales for the week. How much would Connor make in a week in which he made $2175 in sales? How much would Connor make in a week if he made xx dollars in sales?
Earnings when selling $2175:??
Earnings when selling $x: ??
Answer:
[tex]Earnings = 308.75[/tex] ---- (a)
[tex]Earnings = 300 + 0.05x[/tex] -- (b)
Step-by-step explanation:
Given
[tex]Base\ Salary = 300[/tex]
[tex]Commission = 5\%[/tex]
Solving (a): Sales of $2175 in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * 2175[/tex]
[tex]Earnings = 300 + 108.75[/tex]
[tex]Earnings = 308.75[/tex]
Solving (b): Sales of $x in a week.
His total earnings is calculated as thus:
[tex]Earnings = Base\ Salary + Commission * Sales[/tex]
[tex]Earnings = 300 + 5\% * x[/tex]
Convert percent to decimal
[tex]Earnings = 300 + 0.05 * x[/tex]
[tex]Earnings = 300 + 0.05x[/tex]

Given triangle MAT is an isosceles triangle and point H is the midpoint if MT. Prove triangle MHA is congruent to triangle THA
Answer:
There is everything in the image
The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
In an isosceles triangle, the two legs of the triangle are congruent and their opposite angles too.
A triangle MAT is an isosceles triangle and point H is the midpoint of MT.
In triangle ΔMHA and ΔTHA, we have
AH = AH (Common sides)
MH = HT (H is the midpoint of MT)
∠AMH = ∠ATH (Isosceles angles)
The Side-Angle-Side postulate is satisfied. Then the triangle ΔMHA and ΔTHA are congruent with each other.

Lorenzo increases all the prices on his restaurant menu by 8%
Before the increase, the price of a dessert was £4.25
Work out the price of the dessert after the increase.
Answer:
4.59
Step-by-step explanation:
The question requires the price of the desert after the increase
price of the dessert after the increase is £4.59
Price before increase = £4.25
Percentage increase = 8%
Amount of increase = 8% of 4.25
= 8/100 × 4.25
= 0.08 × 4.25
= £0.34
Price after increase = Price before increase + Amount of increase
= £4.25 + £0.34
= £4.59

a. 0.860
b. 0.802
c. 0.057
d. 0.198
Answer:
The answer to this question would normally be, 85.96%, though that isnt an answer choice so the closest thing to it would most likely be answer choice A.
Using the binomial approximation to the normal, it is found that:
0.86 probability that at most 60 say yes, given by option a.
------------------------
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value is:
[tex]E(X) = np[/tex]
The standard deviation 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 z-score 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. Each z-score has a corresponding p-value.The p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X.The probability that the measure is greater than X is 1 subtracted by the p-value.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], if [tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex].
----------------------------
64% use services, thus, [tex]p = 0.64[/tex]87 people are sampled, thus, [tex]n = 87[/tex]The mean and standard deviation are given by:
[tex]\mu = E(X) = np = 87(0.64) = 55.68[/tex]
[tex]\sigma = \sqrt{V(X)} = \sqrt{np(1-p)} = \sqrt{87(0.64)(0.36)} = 4.4771[/tex]
Using continuity correction, the probability that at most 60 use is [tex]P(X \leq 60 + 0.5) = P(X \leq 60.5)[/tex], which is the p-value of Z when X = 60.5, thus:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{60.5 - 55.68}{4.4771}[/tex]
[tex]Z = 1.08[/tex]
[tex]Z = 1.08[/tex] has a p-value of 0.86.
Thus, 0.86 probability that at most 60 say yes, given by option a.

CallmeCarson lol
Answer:
860$
Step-by-step explanation:
In order to find the answer to this question you need to multiply the amount of hours Carson worked to the amount of days he worked and then you need to multiply that by the amount he gets paid per hour.
[tex]21.50 = ph[/tex]
[tex]hours=8[/tex]
[tex]days = 5[/tex]
[tex]8\times5=40[/tex]
So he worked 40 hours a week
[tex]40 \times21.50 = 860[/tex]
Therefore Mr.Carson has made 860$ that week.

A certain fish grows so that after t years of life its length is given by L(t) = 9 − 1/5t inches. Calculate the average rate of growth over the first year of life.
Answer:
Step-by-step explanation:
Given the length of a fish after t years modeled by the equation
L(t) = 9 − 1/5t
The average rate of growth is expressed as;
dL/dt = -1/5 (differential of a constant is zero)
Hence the average rate of growth over the first year of life is -1/5 in/year
