Answer:
0.89417
Step-by-step explanation:
Using the relation to obtain the Zscore :
Z = (x - mean) ÷ standard deviation / sqrt(n)
x = 0.8535
Mean = 0.8565
Standard deviation = 0.0518
Sample size, n = 465
P(x ≤ 0.8535) = (0.8535 - 0.8565) ÷ 0.0518/sqrt(465)
P(x ≥ 0.8535) = - 0.003 / 0.0024021
P(x ≥ 0.8535) = - 1.249
P(Z ≥ - 1.249) = 0.89417

Answer:
n = -7
Step-by-step explanation:
n - 7/4 = 35/12 + 5/3n
subtract n from both sides of the equation:
-7/4 = 35/12 + 2/3n
convert -7/4 to -21/12:
-21/12 = 35/12 + 2/3n
add 21/12 to both sides:
0 = 56/12 + 2/3n
convert 2/3n to 8/12n:
0 = 56/12 + 8/12n
subtract 56/12 from each side:
8/12n = -56/12
multiply both side by 12:
8n = -56
divide both sides by 8:
n = -7

solve for 'x' given that;
3 sin( 3x-20°) = 2 for 0° ≤ x ≤ 180°
Answer:
x ≈ 20.6°
Step-by-step explanation:
3 sin( 3x-20° ) = 2 → sin( 3x-20° ) = ⅔ → 3x - 20° = arcsin(⅔) → 3x = 20° + arcsin(⅔) →
x = ⅓(20° + arcsin(⅔)) , arcsin(⅔) = 41.81°
x = ⅓( 20° + 41.81° ) = ⅓(61.81°) ≈ 20.6°

PLEASE HELP ASAP THANK YOUU: A unicycle wheel makes five rotations. The unicycle travels 37.94 feet. Find the diameter of the wheel in inches.
Show your work and write your answer in a sentence.
Answer:
diameter of the wheel = 28.98 in (2 d.p.)
Step-by-step explanation:
Given information:
A unicycle wheel makes five rotationsThe unicycle travels 37.94 feetCircumference of a circle = πd (where d is the diameter)
One rotation of the wheel is equal to the circumference of the wheel.
Therefore, 5 rotations is equal to the sum of 5 circumferences.
To find the diameter of the wheel in feet, equate the expression for 5 circumferences to the total distance traveled and solve for d:
[tex]\begin{aligned}\textsf{5 circumferences} & = \textsf{total distance traveled}\\\implies 5 \pi d & = \sf 37.94\: ft\\d & = \sf \dfrac{37.94}{5 \pi}\\d & = \sf 2.415335416... \:ft \end{aligned}[/tex]
As 1 foot = 12 inches, multiply the found diameter in feet by 12 to calculate the diameter in inches:
[tex]\begin{aligned}d & =2.415335416... \times 12\\\implies d & = \sf 28.98\:\:in\:(2\:d.p.)\end{aligned}[/tex]
Therefore, the diameter of the wheel is 28.98 in (2 d.p.).

Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?
Answer:
Interest rate = 1.363% (Approx.)
Step-by-step explanation:
Given:
Amount invested P = $220,000
Amount after 10 year = $250,000
Number of year = 10 year
Find:
Interest rate
Computation:
A = P + I
Amount of interest = $250,000 - $220,000
⇒ Amount of interest = $30,000
Amount of interest = PRT
⇒ 30,000 = (220,000)(R)(10)
⇒ 30,000 = (2,200,000)(R)
⇒ R = 0.013636
Interest rate = 1.363% (Approx.)
Si elegimos un día de la semana al azar, ¿qué probabilidad hay de que sea fin de semana (ya sabemos que hay dos días…)?
Answer:
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
La Probabilidad es la mayor o menor posibilidad de que ocurra un determinado suceso. En otras palabras, la probabilidad establece una relación entre el número de sucesos favorables y el número total de sucesos posibles. Entonces, la probabilidad de un suceso cualquiera A se define como el cociente entre el número de casos favorables (número de casos en los que puede ocurrir o no el suceso A) y el número total de casos posibles. Esta se denomina Ley de Laplace.
[tex]P(A)=\frac{numero de casos favorables}{numero de casos posibles}[/tex]
En este caso:
número de casos favorables: 2 (cantidad de días del fin de semana)número de casos posibles: 7 (cantidad de días totales en la semana)Reemplazando:
P(A)= [tex]\frac{2}{7}[/tex]
La probabilidad que hay de que sea fin de semana es [tex]\frac{2}{7}[/tex]

Bryan calculated the area of a square to be 18/32 square foot. Which shows the side length of the square? (Hint: Simplify. Also, area of a square is side x side.)
Answer:
x = 0.75 feet
Step-by-step explanation:
The area of a square is 18/32 square foot
We need to find the side length of the square.
The area of a square of side x is given by :
[tex]A=x^2[/tex]
Substitute all the values,
[tex]x=\sqrt{A} \\\\x=\sqrt{\dfrac{18}{32}} \\\\x=0.75\ feet[/tex]
So, the side length of the square is equal to 0.75 feet.

Step-by-step explanation:
Area is l*w and since the length is known, solve for width
182/13=13w/13
w=14
Answer:
14 units
Step-by-step explanation:
Given, the area of rectangle = 182 square units
length = 13 units
width = ?
By using the formula to find the area of a rectangle, we have
area of rectangle = length * width
182 = 13 * width
182/13 = width
14 units = width

Which equation best represents the relationship between x and y in the table below?
Answer:
y = x² + 5
Step-by-step explanation:
When x = 1:
y = x² + 5
y = 1² + 5
y = 6
When x = 2:
y = x² + 5
y = 2² + 5
y = 9
When x = 3:
y = x² + 5
y = 3² + 5
y = 14

Manuel has scored 27,29 and 28 points in his three basketball games so far. How many points does he need to score in his next game so that his average (mean) is 28 points per game?
Answer:
28.71 points
Step-by-step explanation:
(27.29 + 28 + x) / 3 = 28
(27.29 + 28 + x) = 84
28 + x = 56.71
x = 28.71
The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28.
What is mean?The mean is the average of a data set. Mean gives us an idea of that how much amount of overall data have.
Mean = sum of data / Number of data
As per the given,
Manuel has scored 27,29 and 28 points in his three basketball games so far.
Suppose his score in the fourth game is x.
Mean = (27 + 29 + 28 + x)/4 = 28
(84 + x)/4 = 28
84 + x = 112
x = 28
Hence "The number of points he needs to score in his next game so that his average (mean) is 28 points per game will be 28".
