The diagram shows a convex polygon. 57.67 degrees, is the value of b.
Any polygon whose inner angles are all less than 180 degrees and whose vertices all point outward is said to be convex. It has a minimum of three sides and angles and is closed.
Setting up an equation, we get:
b + 7 + 2b = 180 (sum of angles in a triangle)
3b + 7 = 180
3b = 173
b = 57.67 degrees (rounded to two decimal places).

a deck of cards contains red cards numbered 1,2,3, blue cards numbered 1,2, and green cards numbered 1,2,3,4,5,6. if a single card is picked at random, what is the probability that the card has an even number? select the correct answer below: 211 411 511 1011 711 911
The probability of picking an even card is 1. The correct answer is 1011.
The probability of picking a card with an even number is calculated as the number of even cards over the total number of cards. There are a total of 3 red cards numbered 2, 3 blue cards numbered 2, and 6 green cards numbered 2, 4, 6.
So there are 3 + 3 + 6 = 12 even cards in the deck.
The total number of cards in the deck is
3 red + 3 blue + 6 green = 12 cards.
Therefore, the probability of picking an even card is 12/12 = 1 ,which can be expressed as a fraction, a decimal, or a percentage.
So the correct answer is 1011.

Use the discount equation S = R – rR, where S is the sale price, R is the regular price, and r is the discount rate.
A toy train set with a regular price of $465 is on sale for $387. Find the markdown rate. Round to the nearest tenth of a percent.
%
Answer:
The answer is 16.8%
Step-by-step explanation:
First, find the difference in the price, which is $78. You can then use that number to find the percentage by dividing the difference by the original price, then moving the decimal over to the right twice. You prove this with the discount equation. $387= $465-(16.8%*465). You will get a number similar to 387, but that is only because you are using a rounded percentage.

A machine makes 50 parts. Out of 50 parts, 3 are defective. Using a number or a number range, describe the probability that a randomly selected part is not defective.
The probability that a randomly selected part is not defective is 47/50.
What is probability?Probability is a way of calculating how likely something is to happen. It is difficult to provide a complete prediction for many events. Using it, we can only forecast the probability, or likelihood, of an event occurring. The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.
Here Total number of parts machine makes = 50
Number of parts defective out of 50 = 3
Then number of parts not defective out of 50 = 50-3 = 47.
Now using probability formula:
Probability = No of favorable item/ Total no of item
Now probability that a randomly selected part is not defective is,
= 47/50.
Hence the probability that a randomly selected part is not defective is 47/50.

cars a and b leave town at the same time. car a heads due south at rate of 80 km/hr and car b heads due west at a rate of 60 km/hr. how far is the distance between the cars increasing after three hours?
The distance between the two cars after three hours is 300 km
Cars a and b leave town at the same time.
The speed of the car that went to south = 80 km/hour
The total distance traveled in three hours = 80 × 3
= 240 km
The speed of the car that went to the west = 60 km/hour
The total distance traveled in three hours = 60 × 3
= 180 km
The distance between the two car is the hypotenuse of the right triangle
The distance between the two cars after three hours = \(\sqrt{240^2+180^2}\)
= \(\sqrt{57600+32400}\)
= \(\sqrt{90000}\)
= 300 km
Hence, the distance between the two cars after three hours is 300 km

What is the accumulated value of $1000 invested for 18 years at 4.8% p.a. compounded (a) annually? (b) semi-annually? (c) quarterly? (d) monthly?
The accumulated value of $1000 invested for 18 years at 4.8% p.a. compounded annually is approximately $1956.17, semi-annually is approximately $1964.40, quarterly is approximately $1971.17, and monthly is approximately $1974.46.
To calculate the accumulated value of an investment, we can use the formula for compound interest:
A = P * (1 + r/n)^(n*t)
Where:
A = Accumulated value
P = Principal amount (initial investment)
r = Annual interest rate (in decimal form)
n = Number of times interest is compounded per year
t = Number of years
In this case, we have:
P = $1000
r = 4.8% = 0.048 (converted to decimal)
t = 18 years
Let's calculate the accumulated value for each compounding period:
(a) Annually (n = 1):
A = 1000 * (1 + 0.048/1)^(1*18)
A = 1000 * (1 + 0.048)^18
A ≈ $1956.17
(b) Semi-annually (n = 2):
A = 1000 * (1 + 0.048/2)^(2*18)
A = 1000 * (1 + 0.024)^36
A ≈ $1964.40
(c) Quarterly (n = 4):
A = 1000 * (1 + 0.048/4)^(4*18)
A = 1000 * (1 + 0.012)^72
A ≈ $1971.17
(d) Monthly (n = 12):
A = 1000 * (1 + 0.048/12)^(12*18)
A = 1000 * (1 + 0.004)^216
A ≈ $1974.46
Therefore, the accumulated value of $1000 invested for 18 years at 4.8% p.a. compounded annually is approximately $1956.17, semi-annually is approximately $1964.40, quarterly is approximately $1971.17, and monthly is approximately $1974.46.

consider the random experiment of rolling a pair of fair dice. what is the probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up?
The probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up is 3/16.
To find the probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up, we can use conditional probability.
First, let's consider the possible outcomes when rolling a pair of fair dice.
There are a total of 36 possible outcomes, since each die has 6 possible outcomes (numbers 1 to 6)
and there are 6 possibilities for the second die for each outcome of the first die.
Next, let's consider the outcomes where one of the dice has the number 3 or less facing up and the other has at least the number 3 facing up.
If the first die has the number 3 or less, there are 3 possible outcomes:
(1,3), (2,3), (3,3). If the second die has at least the number 3 facing up, there are 16 possible outcomes:
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,3), (5,3), (6,3), (4,4), (4,5), (4,6), (5,4), (5,5), (5,6), (6,4), (6,5), (6,6).
Out of these 16 outcomes, 3 outcomes also satisfy the condition that the first die has the number 3 or less facing up: (3,3), (4,3), (5,3).
Therefore, the probability that one of the dice has the number 3 or less facing up given that the other has at least the number 3 facing up is 3/16.

d) purposive
The variety of nonrandom sampling that takes proportions into consideration is: c) quota
Quota sampling is the variety of nonrandom sampling that takes proportions into consideration. In quota sampling, the researcher selects a specific number of participants from each subgroup of the population based on their proportion in the overall population. This ensures that the sample represents the different subgroups in the population proportionately.
In quota sampling, the researcher selects participants based on specific characteristics or proportions to ensure that the sample represents the target population accurately. The researcher sets quotas for different groups or segments based on known proportions or desired representation in the population.
For example, if a population consists of 60% males and 40% females, a quota sample might be designed to include the same proportions of males and females. The researcher would continue to select participants from each group until the quotas are met.

An independent basic service set (IBSS) consists of how many access points?
An independent basic service set (IBSS) does not consist of any access points.
In an IBSS, devices such as laptops or smartphones connect with each other on a peer-to-peer basis, forming a temporary network. This type of network can be useful in situations where there is no existing infrastructure or when devices need to communicate with each other directly.
Since an IBSS does not involve any access points, it is not limited by the number of access points. Instead, the number of devices that can be part of an IBSS depends on the capabilities of the devices themselves and the network protocols being used.
To summarize, an IBSS does not consist of any access points. Instead, it is a network configuration where wireless devices communicate directly with each other. The number of devices that can be part of an IBSS depends on the capabilities of the devices and the network protocols being used.

Answer:
Step-by-step explanation:
Begin by combining like terms and then factoring. Combining like terms will give you
\(10p^2-17p-20=0\) Using the "old-fashioned" way of factoring, the a times c method, our a = 10, b = -17 and c = -20.
a * c = 10(-20) = -200 and now we need the factors of 200 (don't worry about the negative) that combine to give us that middle term, -17p (here is where the negative matters). The factors of 200 are:
1. 200; 2, 100; 4. 50; 5, 40; 8, 25; 10, 20
The combination of those numbers that can be manipulated to give us a -17p is the 8, 25 as long as we say that the 25 is negative and the 8 is positive. Rewrite the original polynomial to reflect those factors:
\(10p^2-25p+8p-20=0\) and then factor by grouping:
\((10p^2-25p)+(8p-20)=0\) and factor out from each set of parenthesis what is common:
\(5p(2p-5)+4(2p-5)=0\) again factor out what is common:
(2p - 5)(5p+ 4) = 0. These are the factors; therefore the solutions are
2p - 5 = 0 so
2p = 5 and
p = 5/2 and
5p + 4 = 0 and
5p = -4 so
p = -4/5
