Answer:
[tex]\bar x = 83.1875[/tex]
Step-by-step explanation:
Required
Determine the arithmetic mean
This is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{82 +95 +85 +80 +78 +82 +86 +96 +73 +68 +91+ 80+ 90+ 86 +72 +87}{16}[/tex]
[tex]\bar x = \frac{1331}{16}[/tex]
[tex]\bar x = 83.1875[/tex]
A book with 53 pages numbered 1 to 53 has its pages renumbered in reverse, from 53 to 1. For how many pages do the new page number and old page number share the same units digit?
Answer:
Page number 27 is the one whose order has not changed
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
Each page is assigned two numbers. We can generalize the numbers assigned to page x to be the pair x and 54-x for 1 ≤ x ≤ 53. That is, if x = 1, then we can see that page number one is assigned the numbers 1 and 54-1 = 53. It is fairly easy to see that the unit digits of x and 54-x will only be the same if x has a unit digit of 2 or a unit digit of 7. Thus, we simply must count how many such x there are between 1 and 54. Possibilities for x are 2, 7, 12, 17, 22, 27, 32, 37, 42, 47, and 52. Therefore, there are 11 such pages.

3s(4+6)^2 is an example of
A. an algebraic equation
B. a numerical expression
c. a numerical equation
D. an algebraic expression
Answer:
the answer for this is D.
Step-by-step explanation:
it is a combination of letters operations and variables.But it is not equated (=) to something that is why it is not an algebraic equation.It is also not a numerical equation or numerical expression because it does not consist of only numbers.
3s(4+6)² is an example of an algebraic expression.
What is an algebraic expression?"An algebraic expression is an expression built up from integer constants, variables, and the algebraic operations."
The given expression is:
3s(4+6)²
The given expression is not an equation as it does not contain an equal sign. It is an expression.
Therefore, it is neither algebraic nor numerical equation.
Now, it contains a variable 's'.
Therefore, it is not a numerical expression.

What is the slope of the line with points (-3, 2) and (-3, -2)?
Answer:
-4
Step-by-step explanation:
(-3 , 2) = (x1 , y1)
(-3 , -2) = (x2 , y2)
slope (m) = y2 - y1/x2 - x1
=-2-2/-3-(-3)
=-4/-3+3
=-4/0
=-4
Answer:
No slope.
Step-by-step explanation:
We want to find the slope of the line with the points (-3, 2) and (-3, -2).
To find the slope of any line, we can use the slope formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We can let (-3, 2) be (x₁, y₁) and (-3, -2) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-2)-(2)}{(-3)-(-3)}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{-2-2}{-3+3}=\frac{-4}{0}[/tex]
Anything divided by zero is undefined.
Therefore, the slope does not exist. The line has no slope.
If you plot the two points and graph the line, you can see that it is a vertical line. If you recall, vertical lines have no slopes.

A. Nonlinear function
Step-by-step explanation:
No vertical line intersects the graph in more than one place, so it is a function (not a "relation").
The graph is not a straight line, so is not a linear function. It is a nonlinear function.

nonlinear function
Step-by-step explanation:
A linear function is a straight line, a nonlinear function is a curved line, and a relation is a relationship between two points on a graph, such as an equation.
If the news gives a prediction of a 75% chance of rain tomorrow, what is the probability that it will not rain tomorrow?
Plz ASAP with explanation please
Answer:
25%
Step-by-step explanation:
There is always a total of 100% probability, no matter how many options there are. In this case, it either rains or it doesn't. If there is a 75% chance of rain, the chance of no rain must combine with 75% to make 100%. 100% - 75% = 25%.
1. A baseball is thrown directly upward with
an initial velocity of 96 feet per second
from an initial height of 7 feet. The height
of the ball (in feet) after t seconds is given
by the formula h(t) = -16 t + 96t + 7.
a) After how many seconds will the ball
reach its maximum height?
b) What is that maximum height?
Answer:
a) The ball reaches it's maximum height after 3 seconds.
b) The maximum height of the ball is of 151 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
In this question:
The height of the ball is modeled by:
[tex]h(t) = -16t^2 + 96t + 7[/tex]
So a quadratic equation with [tex]a = -16, b = 96, c = 7[/tex]
a) After how many seconds will the ball reach its maximum height?
t-value of the vertex. So
[tex]t_{v} = -\frac{96}{2(-16)} = 3[/tex]
The ball reaches it's maximum height after 3 seconds.
b) What is that maximum height?
h of the vertex.
[tex]\Delta = b^2 - 4ac = (96)^2 - 4(-16)(7) = 9664[/tex]
[tex]h_{v} = -\frac{9664}{4(-16)} = 604[/tex]
The maximum height of the ball is of 151 feet.

Explain how special right triangles, reference angles, and quadrants of a coordinate grid help us find the exact answer to the following: cos 210°.
9514 1404 393
Answer:
cos(210°) = -(√3)/2
Step-by-step explanation:
The terminal ray of a 210° angle is in the third quadrant. The angle it makes with the -x axis is (210° -110°) = 30°. This is the "reference angle". In the 3rd quadrant, the x-coordinate of the terminal ray's intersection with the unit circle has a negative sign. This will be the sign of the cosine of the angle.
__
The reference angle of 30° tells you that the trig functions of the angle can be found from the side ratios of the "special right triangle" with angles of 30°, 60°, and 90°. The side ratios, shortest to longest, in that triangle are 1 : √3 : 2.
The cosine of the angle is the ratio ...
Cos = Adjacent/Hypotenuse
In the above special triangle, the side adjacent to the 30° angle is the one that is √3 ratio unis. The hypotenuse is 2 ratio units. So, the cosine of 30° is ...
cos(30°) = (√3)/2
As we said above, the sign of the adjacent side of the reference angle for 210° has a negative value. (The hypotenuse is always considered to be positive.) Then the desired cosine is ...
cos(210°) = -cos(30°)
cos(210°) = -(√3)/2
Can someone please help me with and explain this?
Answer:
A
Step-by-step explanation:
Point R is (1, 5).
The transformation (x + 1, y - 1) denotes a translation of one unit to the right and one unit downwards.
Simply add one to the x-coordinate and subtract one to the y-coordinate of R. Hence:
[tex]R'=((1)+1, (5) -1)=(2, 4)[/tex]
Next, we want to dilate RUST by a scale factor of three. Since the dilation is centered on the origin, we can simply multiply each coordinate by three. This yields:
[tex]R'=(3(2), 3(4))=(6, 12)[/tex]
Our answer is A.

Step-by-step explanation:
13/10+2/100=?/100
Get a common denominator of 100 for the first term
13/10 * (10/10) +2/100=?/100
130/100 + 2/100 = ?/100
