Laura babysat 8 nights during the month of July. She earned $22, $30, $35, $25, $25, $20, and $27 for seven nights. How much did she earn the eighth time if the mean of the data is $26.50?
Answer:
$28
Step-by-step explanation:
Given:
data = [22,30,35,25,25,20,27]
For eight night, the new list is:
new_data = [22,30,35,25,25,20,27,x]
Mean = 26.50
Mean Formula:
[tex]\displaystyle \large{m=\dfrac{x_1+x_2+x_3+...+x_n}{n} }[/tex]
Therefore:
[tex]\displaystyle \large{26.50=\dfrac{22+30+35+25+25+20+27+x}{8}}[/tex]
Multiply both sides by 8:
[tex]\displaystyle \large{26.50\cdot 8=\dfrac{22+30+35+25+25+20+27+x}{8} \cdot 8}\\\displaystyle \large{212=22+30+35+25+25+20+27+x}[/tex]
Solve for x:
[tex]\displaystyle \large{212=22+30+35+25+25+20+27+x}\\\displaystyle \large{212=184+x}[/tex]
Subtract 184 both sides:
[tex]\displaystyle \large{212-184=184+x-184}\\\displaystyle \large{28=x}[/tex]
Therefore, she will earn $28 in eighth night
The attachment below is the result of combining all eighth data as we get 26.5 through python language with numpy package.
Answer: $28.
Step-by-step explanation: To solve this problem, we should first find the mean of the data with the seven payments that are given already:
22 + 30 + 35 + 25 + 25 + 20 + 27 = 184.
184 / 7 = 26.2857142857.
In order to figure out how much she made the eighth night with the mean of the data being $26.50, we can pick a number and add it to 184 (the total of the seven payments), and divide the total by 8. The number we can try is 28. The work is done below:
184 + 28 = 212.
212 / 8 = $26.50.
Therefore, Laura's payment on the eighth night was $28.
Hope this helps! :)

You have a coin and a bag of marbles. The bag of marbles has 5 marbles of each color: Red, yellow, blue and green. What is the probability of flipping a head and then selecting a blue marble?
Answer:
[tex]\frac{1}{4}[/tex]
Step-by-step explanation:
Since there are a total of 4 colors, and there are 5 of each colors, the total marbles in the bad would be;
5 x 4 = 20
If a color is selected at random the probability would be
[tex]\frac{part}{whole}[/tex]
our part is 5
our whole is 20
so the probability would be;
[tex]\frac{5}{20}[/tex] or [tex]\frac{1}{4}[/tex] when reduced
Hope this helps!

2 x 3.14 x 4 x 120/3603.14 x 8 x 1/325.12/38.37 ≅ 8Find the measure of an angle between 0° and 360° coterminal with the given angle.
-540°
Answer:
Los ángulos coterminales son ángulos que tienen como lado inicial el eje x y tienen el lado terminal común.
Por ejemplo un ángulo de 20º tendría un ángulo cotermiunal en 360º+20º=380º ó en 360º×2+20º= 720º+20º=740º.
a)2560º÷360º =7 ⇒ 7×360º+40º, luego 40º será su ángulo coterminal entre 0º y 360º
b) 3.600º÷360º= 10 ⇒ 10×360º+0, luego 0º será su ángulo coterminal entre 0º y 360º
c) 1.090º÷360º= 3 ⇒ 3×360º+10º, luego 10º será su ángulo coterminal entre 0º y 360º
Step-by-step explanation:
Primero lo que necesitas saber es que los ángulos coterminales son ángulos que tienen como lado inicial el eje x y tienen el lado terminal común.
Por ejemplo: un ángulo de 20º tendría un ángulo coterminal en 360º+20º=380º ó en 360º×2+20º= 720º+20º=740º.
Apartir de lo anterior, aplicamos lo siguiente:
2560º÷360º =7 ⇒ 7×360º+ 40º,
Respuesta: 40º será su ángulo coterminal entre 0º y 360º.

Answer:
SQR = 118
RQT = 62
Step-by-step explanation:
SQR + RQT = 180
10x - 22 + 3x + 20 = 180
13x - 2 = 180
13x = 182
x = 14
Answer:
m∠RQT=62°
m∠SQR=118°
Step-by-step explanation:
m∠SQT=m∠SQR+m∠RQT
180°=(10x-22°)+3x+20°
180°=13x-2°
180°+2°=13x
182°=13x
x=182÷13=14°
x=14°
So,
m∠RQT=3(14)+20°=62°
And,
m∠SQR=10(14)-22°=140°-22°
m∠SQR=118°
Given g(x) = x² - 6x - 16, which statement is true?

How to analyze a second orden polynomial with constant coefficients
In this case we have a second order polynomial of the form x² - (r₁ + r₂) · x + r₁ · r₂, whose solution is (x - r₁) · (x - r₂) and where r₁ and r₂ are the roots of the polynomial, which can be real or complex numbers but never both according the fundamental theorem of algebra.
If we know that g(x) = x² - 6 · x - 16, then the factored form of the expression is g(x) = (x - 8) · (x + 2). Hence, the correct choice of this question with the given polynomial is "The zeros are -2 and 8, because the factors of g are (x + 2) and (x - 8)". [tex]\blacksquare[/tex]

Sophie earned a grade of 72% on her multiple choice history final that had a total of 200 problems. How many problems on the final exam did Sophie get wrong?
Answer:
56 questions.
Step-by-step explanation:
percent got wrong = 100% - percent got correct.
percent got correct = 72%
percent got wrong = 100%-72% = 28% or 0.28
questions got wrong = total questions * percent got wrong.
total questions = 200
questions got wrong = 200*0.28 = 56 questions
Therefore, Sophie got 56 questions wrong.

A bookcase has a mass of 20 kilograms. A book in the bookcase has a mass of 500 grams.
How many books of the same mass would it take to equal the mass of the bookcase?
Enter your answer in the box.
Answer:
Step-by-step explanation:
Remark
You have to convert one of the numbers. It doesn't matter which one, but you can't simply divide one into the other the way the numbers stand.
Conversion
20 kilograms = 20 * 1000 grams / kg
20 kilograms = 20000 grams
Formula
Number of books = mass of bookcase / mass of 1 book
Givens
number of books = ??
mass of bookcase = 20000 grams
mass of one book = 500 grams
Solution
number of books = 20000 / 500
number of books = 40
Answer: 40 books = mass of bookcase

Answer:
1) D. 8 2/6 hotdogs
2) B. 2 1/5 cakes
Step-by-step explanation:
1) If she's dividing 50 hotdogs equally among 6 people, then you would divide 50 by 6 to find how many each person gets.
note: 50 ÷ 6 is the same as [tex]\frac{50}{6}[/tex].
[tex]\frac{50}{6}[/tex] = [tex]8\frac{2}{6}[/tex]
6 can go into fifty 8 times, so there is a whole number of 8. There is 2/6 left over, so the final result is [tex]8\frac{2}{6}[/tex].
2) If Sako makes 11 cakes and wants to share it equally among 5 people, we can divide 11 by 5 to find how many each person gets.
[tex]\frac{11}{5} =2\frac{1}{5}[/tex]
5 can go into eleven 2 times, so there is a whole number of 2. There is 1/5 leftover, so the final result is [tex]2\frac{1}{5}[/tex].
Hence, the answers are D, and B.

Find the area of each polygon each square on the grid represents 1 square centimeter the answers are mixed up at the bottom of the page cross out the answers as you complete the problems
Answer:
Step-by-step explanation:
Area of composite shapes:
13) Figure 1:
Figure1 is a rectangle.
l = 4 cm & w = 2 cm
Area of figure1 = l * w
= 4 * 2
= 8 cm²
Figure2:
Figure2 is a parallelogram
base = b = 4 cm
h = 4 cm
Area of figure2 = b * h
= 4 * 4
= 16 cm²
Area of composite shape = 8 + 16
= 24 cm²
14) Figure1:
Figure 1 is a trapezium. a & b are parallel sides and h is the height
a = 4 cm ; b = 6 cm; h = 4 -2 = 2 cm
[tex]\sf Area \ of \ figure1 =\dfrac{(a+b)*h}{2}[/tex]
[tex]= \dfrac{(4 +6)*2}{2}\\\\= 10 \ cm^{2}[/tex]
Figure2:
Figure2 is rectangle. l = 6 cm ; w = 2 cm
Area of figure2 = 6*2
= 12 cm²
Area of composite shape = 10 + 12
= 22 cm²
15) Figure 1 & figure 2:
Figure 1 and figure 2 are congruent triangles
base = b = 3 cm & h= 4 cm
[tex]\sf area \ of \ figure1 \ and \ figure 2 = 2*\dfrac{1}{2}b*h[/tex]
= b *h
= 3 * 4
= 12 cm²
Figure3:
Figure 3 is a square.
side = 3 cm
Area of figure3 = side *side
= 3 * 3
= 9 cm²
Area of composite shape = 12 + 9
= 21 cm²

Answer:
2147483648
Step-by-step explanation:
The pattern being used is x4.
8 x 4 = 32
32 x 4 = 128
128 x 4 = 512
512 x 4 = 2048
2048 x 4 = 8192
8192 x 4 = 32768
32768 x 4 = 131072
131072 x 4 = 524288
524288 x 4 = 2097152
2097152 x 4 = 8388608
8388608 x 4 = 33554432
