What is multiplication ? In mathematics, multiplication is a way of finding the product of two or more numbers. This is one of the basic arithmetic operations that we use in our daily life. The main application can be seen in the multiplication table. In arithmetic, multiplication of two numbers represents the repeated addition of one number to another. These numbers include integers, natural numbers, whole numbers, fractions, and so on. Multiplying m by n means that m is added to itself n times, or vice versa. Multiplication in mathematics (denoted by an 'x') is an arithmetic operation separate from addition, subtraction, and division. Elementary school students learn the four arithmetic operations on their own and learn how to solve multiplication problems quickly and easily. Multiplication is the process of taking the product of two or more numbers. Multiplication of numbers such as 'a' and 'b' is given as 'a' multiplied by 'b'. In mathematics, the basic description of multiplication is the repeated addition of one number to another. Multiplying single-digit numbers is easy. However, multiplying numbers with two or more digits is a difficult and time-consuming task. Numbers can be multiplied in any order. (3x4 = 4x3)If you want to multiply the number by a multiple of 10, enter the number of zeros equal to the multiple of 10 next to the multiplier (for example, 6 x 100 = 600).When multiplying three numbers, multiply by the smaller number first to do the math quickly, then multiply by the third number.If the multiplication involves numbers with two or three digits, write those numbers in extended form and then multiply. (for example.:45 × 9 = (40 + 5) × 9 = 40 × 9 + 5 × 9 = 360 + 45 = 405)Calculation4.21 * 10 ^ -9 * 7.8 * 10 ^ 15 = 32.838 * 10^6

Tanya, who has a Bronze level plan and only goes to the doctor once a year for an annual exam, is likely to pay the least for healthcare. The correct option is A.
What is health care?Health care refers to the maintenance or improvement of an individual's physical or mental health through the prevention, diagnosis, and treatment of illness, injury, or disease. It encompasses a range of services provided by healthcare professionals.
Based on the information provided, Tanya, who has a Bronze level plan and only goes to the doctor once a year for an annual exam, is likely to pay the least for healthcare.
Bronze level plans typically have lower monthly premiums but higher out-of-pocket costs for healthcare services, such as copays, deductibles, and coinsurance.
Since Tanya only goes to the doctor once a year, she is unlikely to meet her deductible or incur significant out-of-pocket costs.
In contrast, options B, C, and D involve more frequent or more serious healthcare needs, which would likely result in higher out-of-pocket costs for healthcare services.
Thus, the correct option is A.

a recent survey found that 70% of all adults wear sunglasses for driving. in a random sample of 10 adults, what is the probability that at least five wear sunglasses?
Answers
The probability that at least five wear sunglasses is 0.9464
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%).
In a random sample of 10 adults, the probability that at least five wear sunglasses
P(X ≥ 5) = P(X = 5) + P(X = 6 ) + P(X=7) + P(X=8) + P(X=9) + P(X=10)

Answers
The probability that at least one of the cards drawn is a 3 is 1/5 0r 0.2000.
What is probability?
Probability shows the likelihood of an event happening. It can be calculated by dividing the number of outcomes of an event by the total number of possible outcomes or sample space. Probability is equal to '1' when the event is certain to occur. i.e P =1. It is less than '1' when it is not likely to occur. i.e P< 1
Probability P=no. outcomes/total no. of the possible outcomes
From the question;
No. of total no of cards =5
The probability the card drawn is a 3 =1/5

Adding both the equations , we get
2a = 504
a = 504/2
a = 252 miles per hour
and b = 280 - 252 = 28 miles per hour .
Therefore , The speed of the plane is 252 miles per hour and the speed of the wind is 28 miles per hour .
