The inequality to represent the perimeter of the triangle is given by (2n + 3) + (2n + 2) + n ≤ 30
The solution to the inequality is n ≤ 5 The largest possible lengths of the sides is 13 cmInequality to represent the perimeter of a trianglePerimeter of the triangle = not more than 30 cmSide a = (2n + 3)cmSide b = (2n + 2) cmSide c = n cmSide a + side b + side c ≤ perimeter of the triangle
(2n + 3) + (2n + 2) + n ≤ 30
open parenthesis2n + 3 + 2n + 2 + n ≤ 30
5n + 5 ≤ 30
substract 5 from both sides
5n ≤ 30 - 5
5n ≤ 25
divide both sides by 5n ≤ 25/5
n ≤ 5 cm
The largest possible lengths of the sides is:
Side a = (2n + 3)cm
= 2(5) + 3
= 10 + 3
= 13 cm
Side b = (2n + 2) cm
= 2(5) + 2
= 10 + 2
= 12 cm
Side c = n cm
= 5 cm
So therefore, the largest possible length of the triangle is 13 cm

Jose has $580 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $284.52. He buys 4 bicycle reflectors for $15.65 each and a pair of bike gloves for $11.31. He plans to spend some or all of the money he has left to buy new biking outfits for $31.95 each. What is the greatest number of outfits Jose can buy with the money that's left over?
The greatest number of outfits Jose can buy is 6
How to determine the greatest number of outfits he can buy?The given parameters are:
Budget = $580New bicycle = $284.524 bicycle reflectors = $15.65 eachPair of a bike gloves = $11.31New biking outfits = $31.95 each.Let the number of new biking outfits be x
So, we have
New bicycle + 4 * price of bicycle reflectors + Pair of a bike gloves + New biking outfits ≤ Budget
This gives
284.52 + 4 * 15.65 + 11.31 + 31.95x ≤ 580
This gives
358.43 + 31.95x ≤ 580
Solve the inequality
31.95x ≤ 221.57
Divide
x ≤ 6.93
This gives
x ≤ 6
Hence, the greatest number of outfits is 6

The cluster sample represents the the characteristic of group of same types objects.
What is the cluster sampling?
A population is divided into clusters, such as districts or schools, and some of these clusters are randomly chosen as your sample via the probability sampling technique known as cluster sampling. In a perfect world, each cluster would be a tiny reflection of the entire population.
A researcher intends to carry out a study to evaluate sophomores' abilities in business education across the United States. There is no way to carry out a research study with participants from every university. Instead, the researcher can group the universities from each city into a single cluster by utilizing cluster sampling. The sophomore student population in the United States is then comprised of these clusters. Next, select clusters at random for the research project using either simple random sampling or systematic random sampling. The sophomores from each of these determined groups can then be picked on whom to perform the research study utilizing simple or systematic sampling.

suppose that 10 green balls and 14 purple balls are placed in an urn. two balls are then drawn in succession. what is the probability that the second ball drawn is a purple ball if the first ball is replaced before the second is drawn? a) 0.1224 b) 0.6250 c) 0.8333 d) 0.4167 e) 0.5833 f) none of the above.
The probability that the second ball drawn is a purple ball is (e) 0.5833
How to determine the probability?From the question, we have the following parameters that can be used in our computation:
Green balls = 10
Purple balls = 14
This means that the total number of balls is
Total = 10 + 14
Evaluate the equation
So, we have
Total = 24
From the question, we understand that the ball is replaced
So, the probability that the second ball is purple ie
P(second purple) = purple/total
This gives
P(second purple) = 14/24
Evaluate
P(second purple) = 0.5833
Hence, the probability is (e) 0.5833

There is a 0.48 percent chance that your phone will not be found and will therefore be stolen.
Define the law of total probability?A fundamental statistician's rule governing conditional and marginal probabilities is known as the Total Probability Rule/Law of Total Probability. According to the rule, if the chance of an occurrence is uncertain, it can be derived using the probabilities of numerous different instances that have already transpired.Let P(S|L) represent the likelihood that your phone was stolen if you left it in the computer lab.
Let P(S|C) indicate the likelihood that your phone was stolen if you left it at the cafe.
The likelihood that your phone will be stolen can be determined using law of total probability by:
P(S) = P(S|L)P(L) + P(S|C)P(C)

A seasoning blend is 4% onion powder, by mass? How much pure onion powder should they include in a 72g bottle to make the final blend have 20% onion powder.
Answer: 14.4g of onion powder
Step-by-step explanation: To get 20% of a number, you need to divide the original amount by 5, so 72 ÷5 is 14.4g
They should include 14.4 grams of onion powder in a bottle.
Given that, a seasoning blend is 4% onion powder, by mass.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let x be the seasoning blend.
Now, 4% of 72=20% of x

Find the length of the missing segment.
In accordance to Thales's theorem, the geometric system has a missing side length of 15 units.
How to determine missing lengths in geometric systems by ratiosIn this problem we find a geometric system formed by two proportional trapezoids. This similarity and proportionality is defined by Thales's theorem, which states that a triangle segmented by several lines parallel to each other and parallel to the base of the figure creates triangles and quadrilaterals proportional to each other.
Then, two figures of the given trapezoids are represented by side proportionality ratios. Then, the proportionality ratio is described and its variable x is cleared within by algebra properties:
First, define the proportionality ratio associated to the geometric system:
4 / (10 + 4) = (21 - x) / 21
Second, simplify the equation and clear the variable x:
4 / 14 = 1 - x / 21
2 / 7 = 1 - x / 21
42 / 7 = 21 - x
6 = 21 - x
x = 21 - 6

The solution set for the given quadratic equation is (-0.62, -5.38).
The given equation is 3x(x+6)=-10.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Now, 3x(x+6)=-10
⇒ 3x²+18x=-10
⇒ 3x²+18x+10=0
By comparing 3x²+18x+10=0 with ax²+bx+c=0, we get
a=3, b=18 and c=10
Using quadratic formula x = [-b ± √(b² - 4ac)]/2a
= [-18 ± √(18² - 4×3×10)]/2×3
= [-18 ± √(324 - 120)]/6
= [-18 ± √(204)]/6
= [-18 ± √(204)]/6
= [-18 ± 14.28]/6

ST = UV, marked as equal;VT = TV, common side;m∠TVU = 45° > m∠STV = 44°, as marked.According to Hınge theorem if two sides of different triangles are equal and the angles between the two sides are different, then the larger angles has greater side opposite to it.
As TU is opposite to the larger angle, and SV is opposite to smaller angle, then TU > SV.
