Answer:
[tex]6.36\times 10^7[/tex]
Step-by-step explanation:
We are asked to represent 63,600,000 in scientific notation.
To express our given number in scientific notation, we need factors such that first factor is a number between 1 ans 10 and second factor will be power of 10.
[tex]63,600,000=6.36\times 10000000[/tex]
[tex]63,600,000=6.36\times 10^7[/tex]
Therefore, our number in scientific notation would be [tex]6.36\times 10^7[/tex].
A political analyst predicts Mr. Smith will only get 122 votes for mayor. If Mr. Smith only gets 57 votes, what is the political analyst's percent error? Round your answer to the nearest tenth of a percent.
The political analyst's percent error is approximately 53.3%.
Explanation:To find the political analyst's percent error, we need to calculate the absolute difference between the predicted votes and the actual votes, divide it by the predicted votes, and then multiply by 100. The formula for percent error is:
Percent Error = (|Predicted Value - Actual Value| / Predicted Value) * 100
Plugging in the values, we have:
Percent Error = (|122 - 57| / 122) * 100
Calculating the difference: |122 - 57| = 65
Calculating percent error: (65 / 122) * 100 ≈ 53.3%
Therefore, the political analyst's percent error is approximately 53.3%.

Which equations represent hyperbolas?
Answer:
The correct options are 2 and 5.
Step-by-step explanation:
The general form of conics is
[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]
This equation represents the hyperbola if

What is the shape of the following distribution?
{9, 10, 10, 11, 11, 12, 12, 13, 13, 13, 14, 14, 14, 14, 15, 15, 15, 15, 16, 16, 16, 16, 17, 17, 17, 17, 18, 19, 20}
negative skew
postive skew
symmetric
asymmetric with no skew
none of the above
The distribution is positively skewed, as indicated by the longer tail on the right side of the dataset representing higher values.
The shape of the distribution for the dataset {9, 10, 10, 11, 11, 12, 12, 13, 13, 13, 14, 14, 14, 14, 15, 15, 15, 15, 16, 16, 16, 16, 17, 17, 17, 17, 18, 19, 20} can be determined by looking at the tail of the distribution. Since the values gradually increase and then have a longer tail towards the higher numbers (with the largest values occurring less frequently), we can identify this as a positively skewed distribution. The distribution does not display symmetry, and the tail extends more significantly to the right, which is indicative of a positive skew. This is because the bulk of the data is located on the left side (lower values), while the right side (higher values) stretches out longer due to the presence of outliers or a gradual decrease in frequency.

In adding 4/5 + 18/100 the least common denominator is:
The least common denominator of the given denominators 5 and 100 is 100.
Given that, 4/5 + 18/100.
What is least common denominator?When two or more fractions have the same denominators, they are termed as the common denominators. The least common denominator (LCD) refers to the smallest number that is a common denominator for a given set of fractions.
Here, two different denominators are 5 and 100.
The least common denominator of 5 and 100 is 100.
So, 80/100 + 18/100
= 98/100
= 49/50
Therefore, the least common denominator of the given denominators 5 and 100 is 100.

Marla says that every number in nineties is composite. Jackie says that one number in the nineties is prime. Who is correct?
Answer:
Jackie, 91, 97 is prime.
Step-by-step explanation:
Remember that a number greater than 2 is NOT prime if it is divided by any number different than 1, for example 6 is NOT prime because 3 divides 6. 7 is prime because the only divisors of 7 are 1 and 7.
So for the nineties 90 is divisible by 45.
91 is divisible by 7
92 is divisible by 2
93 is divisible by 3
94 is divisible by 2
95 is divisible by 5
96 is divisible by 2
97 IS PRIME, is just divisible by 1 and 97
98 is divisible by 2
99 is divisible by 3

Vicki started jogging. The first time she ran she ran 3/16 mile. The second time, she ran 3/8 Mile, and the third time, she ran 9/16 mile. If she continue this pattern, when was the first time she ran more than one mile explain
Answer: So the pattern is 3/16, 3/8, 9/16
here you can write 3/8 = 6/16 multiplying numerator and denominator by 2.
Then the sequence is 3/16, 6/16, 9/16....
you can see that is an arithmetic sequence, where in every step you are adding 3/16 to the previous number.
So the next time (the fourth) she will ran (9 +3)/16 = 12/16 mile
the fifth time: (12 + 3)/16 = 15/16 mile
the sixth time : (15 + 3)/16 = 18/16 = 16/16 + 2/16 = (1 + 1/8) miles
So the sixth time she will ran more than one mile.
Which Number produces a rational number when added to 0.25
Any number that is rational when added to 0.25 will result in a rational number, as 0.25 is a rational number itself. Examples include adding integers or other fractions to 0.25.
Explanation:Any number added to 0.25 will produce a rational number since 0.25 itself is a rational number. Rational numbers include integers, fractions, and finite or repeating decimals. When adding a number to 0.25, if the second number is rational, the result will surely be rational. For instance, adding an integer like 2 to 0.25 gives 2.25, which is rational. Similarly, adding a fraction like 1/2, which is 0.5 in decimal form, results in 0.75, also a rational number.
When considering common denominators in fractions for addition or subtraction, the denominator of the resulting number is a product of the denominators of the numbers being added. This is because, to add fractions effectively (or subtract them), we convert each number to an equivalent fraction with the same denominator. Then we add (or subtract) the numerators while the denominator remains constant.
In summary, any number that can be expressed as a fraction with a finite number of digits or a repeating pattern after the decimal point, being a rational number when added to 0.25, will result in another rational number.
To find a number that, when added to 0.25, produces a rational number, we can subtract the decimal part of 0.25 from 0.25 itself. The number that satisfies this condition is -1/4.
Explanation:To find a number that produces a rational number when added to 0.25, we need to understand that a rational number is one that can be expressed as a fraction. So we are looking for a number that, when added to 0.25, results in a fraction.
Let's call the number we're looking for 'x'. To make the addition result in a fraction, 'x' needs to be the negative of the decimal part of 0.25. Since 0.25 is equal to the fraction 1/4, the negative of the decimal part is -(1/4) = -1/4.
Therefore, the number that produces a rational number when added to 0.25 is -1/4.

The circumference of a circle is divided into twelve equal arcs. The measure of each arc is degrees.
The measure of each of the arc in degrees is:
30 degree
Step-by-step explanation:We know that the circle is a whole of 360 degrees.
Now when we divide the circumference of a circle into 12 equal arcs, then the measure of each arc in degrees is calculated as the ratio of the 360 degrees to the number of arcs it has been divided.
Hence, the measure of each arc in degrees is:
[tex]\dfrac{360}{12}=30[/tex]
Hence, the measure in degrees is:
30 degree

Which values of P and Q result in an equation with exactly one solution? Qx-6=Px-103
Answer:
For any value of P & Q except when both are equal , we get One solution of equation.
Step-by-step explanation:
Given: Linear Equation, Qx - 6 = Px - 103
This equation has exactly 1 solution.
To find: Value of P and Q
First we solve the linear equation for value of x,
Qx - 6 = Px - 103
Transpose Px to LHS ( Left hand side ) we get,
Qx - Px - 6 = -103
Transpose 6 to RHS ( Right hand side ) we get,
Qx - Px = -103 + 6
Qx - Px = -97
taking x common in LHS, we get
( Q - P ) x = -97
Traspose ( Q - P ) to RHS, we get
[tex]x=\frac{-97}{Q-P}[/tex]
[tex]x=\frac{-97}{-(P-Q)}[/tex]
[tex]x=\frac{97}{P-Q}[/tex]
Thus, we are get only 1 value of x but it exist if P ≠ Q
otherwise no solution exist for the given linear Equation.
Therefore, For any value of P & Q except when both are equal , we get One solution of equation.
