Susan gets a haircut that cost $20 she leaves a 15% tip. she also has to pay 8.4% sales tax. how much will it cost.
Answer:
$24.68
Step-by-step explanation:
15% of 20=3
8.4% of 20=1.68
20+3+1.7=24.68
I did this by multiplying .15 by 20 to get 3, and multiplying .084 by 20 to get 1.68. Again, add it all together to get $24.68.

10 units is the distance between point A and point C on the number line.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to find the distance between point A and point C on the number line.
A number line is a picture of a graduated straight line that serves as visual representation of the real numbers.
The length along a line or line segment between two points on the line or line segment is known as distance.
The point A is at -3.
The point C is at 7
Now the distance between A and C is AC.
AC=OC-OA
=7-(-3)
=7+3
=10
Hence, 10 units is the distance between point A and point C on the number line.

write an equation of the line that passes through 4,-2 and is parallel to y=-4x+1
Answer:
y=-4x+14
Step-by-step explanation:
A parallel line must always have the same slope, so it must be -4x, and on a graph y=-4x+14 passes through the point (4,-2)
The following are the heat-producing capacities of coal from two mines (in millions of calories per ton): Mine A: 8,500, 8,330, 8,480, 7,960, 8,030 Mine B: 7,710, 7,890, 7,920, 8,270, 7,860. Assuming that the data constitute independent random samples from normal populations with equal variances, construct a 99% confidence interval for the difference between the true average heat-producing capacities of coal from the two mines.
Answer: The confidence interval will be -91.87 < μ₁-μ₂ <751.87
Step-by-step explanation: Confidence Interval is the interval of certainty in which the true population mean is in.
In a confidence interval for the difference between two averages with a sample size less than 30, the calculations are:
[tex]x_{1}-x_{2}[/tex] ± [tex]t.S_{p}\sqrt{\frac{1}{n_{1}} +\frac{1}{n_{2}} }[/tex]
in which
x₁ and x₂ are the sample mean of each data set
t is the probability found in the t-table whose df = n₁ + n₂ - 2
[tex]S_{p}[/tex] is the pooled estimate of the common standard deviation, assuming variances are similar, and can be calculated as:
[tex]S_{p}=\sqrt{\frac{(n_{1}-1)(s_{1})^{2}+(n_{2}-1)(s_{2})^{2}}{n_{1}+n_{2}-2} }[/tex]
n₁ and n₂ are sample sizes
The data to construct the interval are:
Mine A:
x₁ = 8260
s₁ = 251.9
n₁ = 5
Mine B:
x₂ = 7930
s₂ = 206.52
n₂ = 5
Then:
[tex]S_{p}=\sqrt{\frac{(5-1)(251.9)^{2}+(5-1)(206.52)^{2}}{8}[/tex]
[tex]S_{p}=\sqrt{\frac{253814.44+170602.04}{8}[/tex]
[tex]S_{p}=[/tex] 230.33
Using a table, for a 99% confidence and df = 8, t-score = 2.896.
Doing calculations:
(8260-7930) ± (2.896)(230.33)([tex]\sqrt{\frac{1}{5} +\frac{1}{5} }[/tex])
330 ± (2.896)(230.33)([tex]\sqrt{0.4}[/tex])
330 ± 421.87
Interval will be
[tex]-91.87<\mu_{1}-\mu_{2}<751.87[/tex]
A 99% confidence interval for the difference between the true average heat-producing capacities of coal from the mines is between -91.87 and 751.87

Divide. 5,346 ÷ 29 Enter your answer in the boxes as a mixed number in simplest form.
Answer:
[tex]190\frac{26}{29}[/tex]
Step-by-step explanation:
____190__
29 | 5346
-29 (29*100=2900)
________
2446
-232 (29*90=232)
________
26
Therefore, the answer is [tex]190\frac{26}{29}[/tex]
In the mixed form we can write → 5346 ÷ 29 as [tex]$184\frac{10}{29} .\\[/tex]
We have the following operation -
5346 ÷ 29
We have to write the result of above division in mixed form.
What is Division Algorithm ?The division algorithm says when a number 'a' is divided by a number 'b' gives the quotient 'q' and the remainder 'r' then the following relation exists-
a = bq + r
where 0 ≤ r < b.
This is also known as Euclid's division lemma.
According to the question, we have -
5346 ÷ 29
Let A = 5346 ÷ 29. Therefore -
A = [tex]$\frac{5346}{29} = 184\frac{10}{29} .\\[/tex]
Hence, in the mixed form we can write → 5346 ÷ 29 as [tex]$184\frac{10}{29} .\\[/tex]

The center of a circle is located at the point (1,1). The point (6,3) is located on the circle.
What is the radius of the circle?
Answer:
Square root of 29
Step-by-step explanation:
The required radius of the circle would be √29 units which circle with a center at (1, 1) and a point on the circle is (6, 3).
What is the equation of a circle?The equation of a circle with center (h,k) and radius r is :
r² = (x−h)² + (y−k)²
Given that a circle with a center at (1, 1) and a point on the circle is (6, 3).
Since the circle passes through points (6, 3),
So the radius (r) of the circle is the distance between points (1, 1) and (6,3).
⇒ r² = (6 - 1)² + (3 − 1)²
⇒ r² = (5)² + (2)²
⇒ r² = 25 + 4
⇒ r² = 29
⇒ r = √29
Therefore, the required radius of the circle would be √29 units.

Month June July Aug Sept Oct
Rainfall (in.) 6.14 7.19
8.63
8.38 6.47
2.43
2. The table shows monthly rainfall in inches for
five months. Identify the outlier in the data set.
Determine how the outlier affects the mean,
median, and mode of the data. Then tell which
measure of center best describes the data with
and without the outlier. Round to the nearest
hundredth. Justify your selection.
okay, first to figure out the IQR of the table you need to organize them from least to greatest.
2.43, 6.14, 6.47, 7.19, 8.38, 8.63
to find the middle number of all of these you add them all together and divide by 6, which is the total amount of numbers there.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 = 39.24
39.24 / 6 = 6.54
now that we have the IQR, next we find the outlier. to find the outlier you multiply the IQR by 1.5 which is 6.54 x 1.5 = 9.81 <- outlier
Outliers affect the mean value of the data but have little effect on the median or mode of a given set of data.
2.43 + 6.14 + 6.47 + 7.19 + 8.38 + 8.63 + 9.81 = 49.05
49.05 / 7 = 7.00 (Rounded)

Tropical Storm Zeta will bring 0.36 in. of rain to New Orleans. Which fraction is equivalent to this amount of rain in inches?
Answer: 9/25 inches of rain
Step-by-step explanation: Put the decimal (0.36) over its place value (100), which turns it into 36/100. Now, simplify by dividing the numerator (36) and the denominator (100) by the greatest common factor (4), to get the answer 9/25.

Answer:

Step-by-step explanation:
.The square of a real number c is 11 less than the square of 5.
In an earlier chapter we learned that
32=3⋅3=9
We said that 9 was the square of 3. The square of -3 is 9 as well
(−3)2=(−3)⋅(−3)=9
3 and -3 are said to be the square roots of 9.
All positive real numbers has two square roots, one positive square root and one negative square root. The positive square root is sometimes referred to as the principal square root. The reason that we have two square roots is exemplified above. The product of two numbers is positive if both numbers have the same sign as is the case with squares and square roots
a2=a⋅a=(−a)⋅(−a)
A square root is written with a radical symbol √ and the number or expression inside the radical symbol, below denoted a, is called the radicand.
a−−√
To indicate that we want both the positive and the negative square root of a radicand we put the symbol ± (read as plus minus) in front of the root.
±9–√=±3
Zero has one square root which is 0.
0–√=0
Negative numbers don't have real square roots since a square is either positive or 0.
If the square root of an integer is another integer then the square is called a perfect square. For example 25 is a perfect square since
±25−−√=±5
If the radicand is not a perfect square i.e. the square root is not a whole number than you have to approximate the square root
±3–√=±1.73205...≈±1.7
The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers. The decimal form of an irrational number will neither terminate nor repeat. The irrational numbers together with the rational numbers constitutes the real numbers.
Example
irrationalnumber⇒19−−√≈4.35889...
rationalnumber⇒0.5=12
The value of c if, The square of a real number c is 11 less than the square of 5 is 3.74.
What is equation?In other terms, an equation is a mathematical statement stating that "this is equivalent to that." It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given:
The square of a real number c is 11 less than the square of 5,
Write the equation as shown below,
c² = 5² - 11
c² = 25 - 11
c² = 14
