the volume of water is usually distributed with a mean of 62ml and standard deviation of 40ml. What is the probability that the volume will be greater than 90ml?
The probability of the volume of water being over 90 ml is 24.10%.
What exactly is the standard normal distribution?A symmetric probability distribution only with equal mean, mean, as well as mode values is known as a standard normal distribution.A statistical table as well as computer software is used to estimate the likelihood of a standard normal distribution.For the given question;
The mean of the sample is; μ = 62 ml.
The standard distribution is; σ = 40 ml.
The probability of the values must lie more than 90 ml.
Thus,
P(x > 90) = P[ (x - μ)/ σ ]
Substitute the values;
P(x > 90) = 1 - P[ (90 - 62)/ 40]
P(x > 90) = 1 - P[0.7]
P(x > 90) = 1 - 0.758
P(x > 90) = 0.2410
P(x > 90) = 24.10%
Therefore, the probability that the the volume of water will be greater than 90 ml is 24.10%.

Find an equation of the tangent line to the curve at the given point.
y = x³ - 3x + 1, (3, 19)
Answer:
y=24x-53.
Step-by-step explanation:
1) the slope-interception view of the required tangent line is
y=slope*x+interception;
2) y'=3x²-3;
3) slope=y'(3), then slope=3*3²-3=24;
4) the required equation of tangent line has the form
y=24x+interception;
5) to calculate the interception it is needed to substitute the given coordinates (3;19) into this equation:
19=24*3+interception; ⇒ interception=-53;
6) finally, the required equation is y=24x-53.
The governor of state A earns $54,900 more than the governor of state B. If the total of their salaries is $310,850, find the salaries of each.
Step-by-step explanation:
Let the earning of governor of state B be x then
we have,
Earning of A = 54900 + x
Earning of B = x
according to question,
Earning of A + Earning of B = 310850
54900 + x + x = 310850
2x = 255950
x = 127975
earning of A = 182875$
earning of B = 127975$

The two halves of a fraction are the numerator and the denominator. Any arithmetic operation involving two or more fractions, such as addition or subtraction, is possible if the denominators of the two fractions are the same. To this, the phrase "common denominator" relates.
When two fractions have the same denominator, we refer to them as having common denominators. Common denominators facilitate fractional operations like comparison, addition, and subtraction.
Give common denominators to the terms on each side now.
4/20+5/20>3/6 X-2/6 X

(3x)^3 3^3 x^3 =????
Answer: 729x^6
Step-by-step explanation: I got this answer because I first multiplied the 3^3 which is 27
then the equation is 27x^3 times 3^3x^3. Then you do the same thing on the other side which is 27x^3. So 27x^3 times 27x^3. After that you multiple 27 and 27 which is 729, don’t forget your x^3 and x^3 which is x^6 so your answer is 729x^6.
Determine whether the given ordered pair is a solution of
the system of equations.
(8, 7); -x+y= - 1
6x + y = 41
Answer:THE ANSWER IS NO.
Step-by-step explanation:
As we have given that x=8 and y=7
put theses values in given equations :-
-x + y= -1
-8+7= -1,true
But, for 6x+y=41
We get 6*8+7=41
55 ≠41
Hence the answer is NO.
Answer:
Step-by-step explanation: if the ordered pair (8,7) is a solution of a system of equations; the values x=8, y=7 substituted in the system must make both equations true. -8+7=-1 -1=-1 √ 6×8+7=41 48+7=41 55=41(8,7) is not a solution of the systems.

Write the equation of the line in fully simplified slope-intercept form.
The equation of the line in fully simplified slope-intercept form is [tex]y=\frac{1}{4} x-1[/tex].
What is a slope intercept form?A line is defined by the equation y = mx + b, which is also known as the slope-intercept form. When the line is graphed, m represents the slope and b the point at which the line intersects the y-axis.
For calculating the slope, the formula used is [tex]m=\frac{x_{2} -x_{1} }{y_{2} -y_{1} }[/tex]
From the graph we see that the points are (4,0) and (0,-1).
Substituting the points in the formula,
[tex]m=\frac{x_{2} -x_{1} }{y_{2} -y_{1} }\\m=\frac{-1-0}{0-4} \\m=\frac{-1}{-4} \\m=\frac{1}{4}[/tex]
We know that, the equation of a line in point slope form, where (x₁, y₁) is the point and slope m is:
(y – y₁) = m(x – x₁)
Here, (x₁, y₁)= (4,0)
Substitute the value of m and any coordinate into the formula y−y₁=m(x−x₁)
[tex]y-0=\frac{1}{4} (x-4)\\y=\frac{1}{4} x-1[/tex]
Therefore, the equation of the line in fully simplified slope-intercept form is [tex]y=\frac{1}{4} x-1[/tex].

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 48 ft, find its length and width.
Formula we use,
→ P = 2(L + W)
Then the value of L and W is,
→ P = 2(L + W)
→ 48 = 2(2x + x)
→ 2(3x) = 48
→ x = 48/6
→ [ x = 8 ]
Then the width will be,
→ W = x = 8 ft
Hence, the width is 8 ft.
Now the length will be,
→ L = 2x = 2(8) = 16 ft
Therefore, the length is 16 ft.

Triangle PQR has vertives P(2, -4), Q(4, -5), and R(7, -2). It is translated 6 units left and 3 units up to produce Triangle P'Q'R'. Complete table.
The coordinates of the triangle P'Q'R' is P'(x, y) = (- 4, - 1), Q'(x, y) = (- 2, - 2) and R'(x, y) = (1, 1), respectively.
What are the locations of the vertices of the triangle after applying rigid transformations?
In this problem we know the three vertices of a triangle on a Cartesian plane and we must determine the coordinates of its image by applying rigid transformations. According to the statement, the vertices of the image are obtained by applying a translation formula:
P'(x, y) = P(x, y) + T(x, y) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting point T(x, y) - Translation vectorIf we know that P(x, y) = (2, - 4), Q(x, y) = (4, - 5), R(x, y) = (7, - 2) and T(x, y) = (- 6, 3), then the coordinates of the vertices of the image are:
P'(x, y) = (2, - 4) + (- 6, 3)
P'(x, y) = (- 4, - 1)
Q'(x, y) = (4, - 5) + (- 6, 3)
Q'(x, y) = (- 2, - 2)
R'(x, y) = (7, - 2) + (- 6, 3)
R'(x, y) = (1, 1)
The coordinates of the triangle P'Q'R' is P'(x, y) = (- 4, - 1), Q'(x, y) = (- 2, - 2) and R'(x, y) = (1, 1), respectively.

Joshua purchased a game card for the arcade for a total of $20. He played three basketball hoop games for $2.25 each and two rounds of air hockey for $1.75 each. How much did he have left on the game card?
1.)$ 13.50
2.)$ 10.25
3.)$ 9.75
4.)$ 6.75
Answer:
b
Step-by-step explanation:
Joshua had $9.75 left on the game card (option 3).
Joshua's expenses on the game card can be calculated as follows:
Cost of playing three basketball hoop games = 3 games * $2.25/game
Cost of playing three basketball hoop games = $6.75
Cost of playing two rounds of air hockey = 2 rounds * $1.75/round
Cost of playing two rounds of air hockey = $3.50
Total expenses = $6.75 + $3.50
Total expenses = $10.25
Joshua originally had $20 on the game card, and he spent $10.25. To find out how much he had left, subtract his expenses from the original amount:
Amount left = $20 - $10.25
Amount left = $9.75
So, Joshua had $9.75 left on the game card.
The correct answer is 3.) $9.75.

How to express in Standard Notation?
Standard notation of a number is defined as when a number is written with only number digits. This is the typical way to write numbers since words are not used in standard number notation.
Now, from conversions, we know that;
1 oz = 0.0078125 gallons
1 qt = 0.25 gallons
Thus, 4 gal 6 qt 112 oz expressed in gallons is;
4 + (6 * 0.25) + (112 * 0.0078125)

Answer:
Option C
Step-by-step explanation:
Given the data set, 23, 32, 20, 13, 27, 36, 29, 38, 23, 15, 30, 18, to find out which box-and-whisker plot matches the data, let's work out the 5-number summary needed for constructing a box plot.
The five-number summary includes the min, Q1, median, Q3 and max value.
Let's find them.
First, order the data set from the least to the largest
13, 15, 18, 20, 23, 23, 27, 29, 30, 32, 36, 38
Min = 13
Max = 38
Median = (23 + 27) ÷ 2 = 50 ÷ 2 = 25
Q1 = (18 + 20) ÷ 2 = 38 ÷ 2 = 19
Q3 = (30 + 32) ÷ 2 = 62 ÷ 2 = 31
