what is the square root of 547
Answers
We can estimate the square root to be between 23 and 24 by hand, and using a calculator we can see that the exact value is 23.388
How to get the square root of 547?
Let's solve this without using a calculator.
To check this, we can just take integer numbers and square them and see which one gives an outcome equal to or closer to 547.
For example, if we start with 20 we get:
20*20 = 400
Let's go higher, if we take 23:
23*23 = 529
The next one is 24:
24*24 = 576
Then we can estimate:
√529 < √547 < √576
23 < √547 < 24
So our number is between 23 and 24, now using a calculator we can get the exact value:
√547 = 23.388

a cog company produces 20 cogs a day, 4 of which are defective. Find the probability of selecting 4 cogs from the 20 produced where all are defective?
Answers
Answer:
1/4845
Step-by-step explanation:
The probability of selecting a defective cog first is
1/5
The second cog is
3/19
The third cog is
1/9
And the fourth cog is
1/17
Multiplying these together we get
1/5 * 3/19* 1/9 * 1/17 = 1/4845
The probability of selecting 4 cogs from the 20 produced where all are defective is approximately 0.000206.
What is probability?Probability is a measure of how likely an event is to occur. Many events are impossible to predict with absolute certainty.
The probability of selecting 4 defective cogs from the 20 produced can be calculated as follows:
P(4 defective cogs) = (Number of ways to select 4 defective cogs) / (Total number of ways to select 4 cogs from 20)
The number of ways to select 4 defective cogs can be found by selecting 4 defective cogs out of the 4 defective cogs produced, and 0 non-defective cogs out of the remaining 20-4=16 non-defective cogs. This can be expressed mathematically as:
Number of ways to select 4 defective cogs = (4 choose 4) * (16 choose 0) = 1
The total number of ways to select 4 cogs from 20 can be found by selecting 4 cogs out of the 20 produced. This can be expressed mathematically as:
Total number of ways to select 4 cogs from 20 = (20 choose 4) = 4845
Therefore, the probability of selecting 4 defective cogs from the 20 produced is:
P(4 defective cogs) = (Number of ways to select 4 defective cogs) / (Total number of ways to select 4 cogs from 20) = 1/4845
Thus, the probability of selecting defective cogs is approximately 0.000206.

The depth of a local lake averages 38 ft, which is represented as |−38|. In February, it measured 6 ft deep, or |−6|, and in July, it was 25 ft deep, or |−25|. What is the difference between the depths in February and July?
A32 feet
B 31 feet
C 19 feet
D 13 feet
Answers
The difference between the depths in February and July is 31 feet.
How to measure depth?The method of measuring depth depends on what we are trying to measure the depth of. Here are some general methods for measuring different types of depth:
Depth of water: The depth of water can be measured using a sounding device such as a sonar or a simple depth gauge. A sonar uses sound waves to determine the distance from the water's surface to the bottom. A depth gauge is a simple device that measures the distance from the surface of the water to the bottom using a weight and a line.
Depth of a hole: The depth of a hole can be measured using a tape measure or a ruler. Simply insert the measuring device into the hole and measure the distance from the top of the hole to the bottom.
Depth of a trench: The depth of a trench can be measured using a measuring tape or a surveyor's level. Place the measuring device at the edge of the trench and measure the distance from the top of the trench to the bottom.
Depth of a pool: The depth of a pool can be measured using a pool depth marker or by using a measuring tape. A depth marker is usually located on the side of the pool and indicates the depth at various points. Alternatively, you can use a measuring tape to measure the distance from the surface of the water to the bottom of the pool.
Depth of a well: The depth of a well can be measured using a well sounder or a tape measure. A well sounder is a device that sends a signal down the well and measures the time it takes for the signal to bounce back. The time it takes is then used to calculate the depth of the well. Alternatively, a tape measure can be used to measure the distance from the surface of the water to the bottom.
Given, In February, it measured 6 ft deep, or |−6| and in July, it was 25 ft deep, or |−25|.
The difference between the depths in February and July is:
|−6| − |−25| = 6 − (−25) = 6 + 25 = 31
Therefore, the correct choice is B) 31 feet.

Easton is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Easton scored a total of 21 points and made twice as many two point shots as three point shots. Write a system of equations that could be used to determine the number of two point shots Easton made and the number of three point shots he made. Define the variables that you use to write the system.
Answers
Answer:
\(2x+3y=21\\x=2y\)
x represents the number of two-point shots. y represent the number of three-point shots.
Step-by-step explanation:
Let's let x represent the number of two-point shots Easton made and let's let y represent the number of three-point shots Easton made.
So, we know that that Easton scored a total of 21 points.
In other words, the amount of two-point shots and amount of three-point shots total 21. In an equation, this is:
\(2x+3y=21\)
The 2 in front of the x represents the two-point per shot, and the 3 in front of the y represents the three-point per shot.
We also know that Easton made twice as many two-point shots as three-point shots. So, we can write this as:
\(x=2y\)
The number of two-pointers x is equivalent to twice the number of three-pointers y.
So, our system of equations is as follows:
\(2x+3y=21\\x=2y\)
Notes:
To solve, use substitution. Substitute the second equation into the first:
\(2(2y)+3y=21\)
Multiply:
\(4y+3y=21\)
Combine like terms:
\(7y=21\)
Divide by 7:
\(y=3\)
Solve for x using the second equation again:
\(x=2(3)=6\)
So, Easton made 6 two-pointers and 3 three-pointers.

Answer:
For the first city, the 95% confidence interval would be:

Total = ⁿCᵣ
Where
n = 11 and r = 6
Substitute the known values in the above equation
Total = ¹¹C₆
Apply the combination formula
ⁿCᵣ = n!/(n - r)!r!
So, we have
Total = 11!/5!6!
Evaluate
Total = 462

It says to order "greatest to least" so that means the biggest number goes first, then smaller next, and the smallest goes last.
sqrt25 is 5 and sqrt28 would be a little bigger, so 5.something. (you can find exactly on a calculator, but we don't need exact)
28/7 is 4 and 35/7 is 5. So 32/7 is in between, so like 4.something.
cuberoot27 is 3 and cuberoot64 is 4. So cuberoot58 is in between, it is 3.something.
So in order from big to small is
5...
4...
3...
which is
sqrt28,
32/7
cubrt58
The order from greatest to least will be the square root of twenty-eight, thirty-two over seven, and cube root of fifty-eight. Then the correct option is A.
What is descending order?It is the order of the numbers in which the biggest number comes first and then followed by the next number and then the last number will be the smallest one.
Order cube root of fifty-eight, thirty-two over seven, square root of twenty-eight from greatest to least.

The expression is converted into decimal form, then we have

Then the order of the numbers from greatest to least will be
√28 > 32/7 > ∛58
The order from greatest to least will be the square root of twenty-eight, thirty-two over seven, and cube root of fifty-eight. Then the correct option is A.

Therefore:
Percentage of win with sellout crowd
