Therefore , the given expression of this problem of square root
2√2 not equal to √2.
What is square root?The value that results from multiplying the square root of an integer by itself is the number.
Example: Since 5* 5 = 25, 5 is the square root of 25. Observe that (5) (5) also equals 25, proving that (5) is a square root of 25.
Here,
In this case, the mathematical symbol for Root 2 is 2.
Root 2 then multiplied by Root 2.
√2 + √2 = 2√2
If we take the estimated value of 2 = 1.4142
Then
=> 2√2 = 1.4142 x 2
=> 2.8284 (approximately)
Please take note that 2 is an irrational number.
Alternatively, root2* root 2
√2 * √2 = 2
Because 2 is just the square root of 2,
Therefore,
what happens when root 2 + root 2 and root2 root 2 are different
2√2 - 2 = 2.8284 - 2 = 0.8284 (approx)
Therefore , the given expression of this problem of square root
2√2 not equal to √2.'

Polling organizations regularly collect data on the public’s opinions and habits. A question on a recent survey asked, “How often do you purchase coffee from a coffeehouse?” There may be differences in how people respond to this question based on whether the person is a full-time student. Suppose a polling organization uses random digit dialing of local phone numbers to take a poll and asks respondents whether they are full-time students. In addition, they ask respondents to identify how often they purchase coffee from a coffeehouse (never, once a week, two to three times a week, daily, more than once a day). The data are collected in a 5-by-2 table of counts. Which of the following is the appropriate null hypothesis when conducting a chi-square test for the data?
Answer:
there is an association between how often a person purchases coffee from a coffee house and whether a person is a full time student.
Step-by-step explanation:
Answer:
C) H0 : How often a person purchases coffee from a coffeehouse is not associated with whether a person is a full-time student.
Step-by-step explanation:
This represents a chi-square test for independence because one sample was taken and two variables were observed. This is an appropriate null hypothesis for a chi-square test for independence in this study as it hypothesizes no association between coffee-purchasing habits and full-time student status.

Alice is a good gambler and always knows when to stop. Suppose in a game, in each round she has a winning probability of 0.8 and she will stop at the first loss. Try to find the upper bound on the probability that she can win at least 10 rounds using Markov's inequality.
Answer:
The answer is "0.500".
Step-by-step explanation:
The chance that round will be won, [tex]P (win) =0.8[/tex]
The likelihood of losing round by complementary law
[tex]P(loss) = 1 -P(win)\\\\[/tex]
[tex]=1-0.8\\\\=0.2\\\\[/tex]
Let X be the number of rounds to the first loss played.
Here, [tex]X \sim Geometric (p=0.2)[/tex]
The PMF of X is the following:
[tex]P(X=x)=p(1-p)^x\\\\[/tex]
[tex]=(0.2)(1-0.2)^x\\\\=(0.2)(0.8)^x, \ \ \ \ \ x=1,2,.....[/tex]
The mean of X is the geometric random variable property, [tex]E(X) =\frac{1}{P}= \frac{1}{0.2}=5\\\\[/tex]
Markov's Inequality:
Suppose X is any random variable that has no negatives. So,
[tex]P(X \geq s)\leq \frac{E(X)}{s} for s >0\\\\[/tex]
Find the upper bound of [tex]P (X \geq 10)[/tex]
[tex]P(X \geq 10) \leq \frac{E(X)}{10}[/tex]
[tex]=\frac{5}{10}\\\\=\frac{1}{2}\\\\=0.5\\\\[/tex]
The highest probability is, therefore, that Markov's inequality will win at least ten rounds: 0.500

A. 8 > (line underneath) 40
B. s < (line underneath) 40
C. s > 40
D. s < 40
Answer: s _< 40
Step-by-step explanation:
The correct inequality which represents the situation is,
⇒ s ≤ 40
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
At a state fair, every go-kart goes at most 40 mi/h.
Now, Let s represent the speed of a go-kart.
Hence, The correct inequality which represents the situation is,
⇒ s ≤ 40
Since, Symbol used for at most is, less than or equal to.
Thus, The correct inequality which represents the situation is,

Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?
Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.

The theoretical probability of picking a one-dollar coin from the piggy bank before the draw is ---%, but the experimental probability, based on the draw, is ---%.
Answer:
First box is 50%
Second box is 60%
Step-by-step explanation:
Took the test and I got it right :)
The theoretical probability of picking a one-dollar coin from the piggy bank before the draw is 50%, But the experimental probability, based on the draw, is 60%
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
P(E) = Number of favorable outcomes / total number of outcomes
Jonathan's piggy bank contains 20 nickels, 30 quarters, and 50 one-dollar coins.
He picks 20 coins from the bank at random; 12 of these coins are one-dollar coins.
The total number of one-dollar coins = 50
Total number of coins the piggy bank contains = 100
The theoretical probability of picking a one-dollar coin from the piggy bank before the draw = 50/100
= 1/2
But the experimental probability, based on the draw, is 60%.

Susie is looking for butterflies in an area where: 15% of the butterflies are of type A 30% of the butterflies are of type B 55% of the butterflies are of type C Suppose that she spots two butterflies on her walk, and that the types of the two butterflies are independent from each other (perhaps because they are spotted in different locations). (a) What is the probability that the two butterflies she spots will both be type A butterflies
Answer:
the probability that the two butterflies she spots will both be type A butterflies is 0.0044
Step-by-step explanation:
The computation of the probability that the two butterflies she spots will both be type A butterflies is shown below:
= 1 ÷ Type A × 1 ÷ Type A
= 1 ÷ 15 × 1 ÷ 15
= 1 ÷ 225
= 0.0044
Hence, the probability that the two butterflies she spots will both be type A butterflies is 0.0044

At a garage sale, Samuel purchased used books and DVDs. He bought a total of 18 items and spent $11. Each book cost $0.50 and each DVD cost $0.75. How many books did Samuel purchase?
Answer: 10 books
Step-by-step explanation:
Let the number of books bought be represented by x.
Let the number of dvds bought be represented by y.
The information given in the question can be formed into an equation as:
x + y = 18 ........ i
0.50x + 0.75y = 11 ....... ii
Multiply equation i by 0.75
Multiply equation ii by 1
0.75x + 0.75y = 13.50 ........ iii
0.50x + 0.75y = 11 ........ iv
Subtract iv from iii
0.25x = 2.50
x = 2.50/0.25
x = 10
Samuel bought 10 books
