Answer:
the probability of getting a total greater than 8 is 10/36=5/18
Step-by-step explanation:
Of the 36 different possible results of rolling a die twice, 10 of them have a total greater than 8.
Therefore, the probability of getting a total greater than 8 is 10/36 which equals 5/18

Answer:
16/35 chapters per hourStep-by-step explanation:
Set a ratio:
7/8 hours ⇒ 2/5 chapters1 hour ⇒ x chaptersFind the value of x by cross-multiplication:
x = 1 × 2/5 ÷ 7/8x = 2/5 × 8/7x = 16/358.
Fit a quadratic function to these three points:
(−2, 8), (0, −4), and (4, 68)
A. y = −2x2 − 2x − 4
B. y = −2x2 + 2x − 4
C. y = 4x2 + 2x − 4
D. y = −4x2 − 2x − 4
Answers
Answer: y= 4x² +2x -4
C. y = 4x2 + 2x − 4
Step-by-step explanation: f(x)=4x^2+2x-4
Given three points
P1(-2,8)
P2(0,-4)
P3(4,68)
We need the quadratic equation that passes through all three points.
Solution:
We first assume the final equation to be
f(x)=ax^2+bx+c .............................(0)
Observations:
1. Points are not symmetric, so cannot find vertex visually.
2. Using the point (0,-4) we substitute x=0 into f(x) to get
f(0)=0+0+c=-4, hence c=-4.
3. We will use the two other points (P1 & P3) to set up a system of two equations to find a and b.
f(-2)=a(-2)^2+b(-2)-4=8 => 4a-2b-4=8.................(1)
f(4)=a(4^2)+b(4)-4=68 => 16a+4b-4=68.............(2)
4. Solve system
2(1)+(2) => 24a+0b-12=84 => 24a=96 => a=96/24 => a=4 ......(3)
substitute (3) in (2) => 16(4)+4b-4=68 => b=8/4 => b=2 ..........(4)
5. Put values c=-4, a=4, b=2 into equation (0) to get
f(x)=4x^2+2x-4
Check:
f(-2)=4((-2)^2)+2(-2)-4=16-4-4=8
f(0)=0+0-4 = -4
f(4)=4(4^2)+2(4)-4=64+8-4=68
So all consistent, => solution ok.

Answer:
y = 4x² + 2x − 4
Step-by-step explanation:
The y-values go down and up again, so the parabola opens upward. That means the x² coefficient must be positive. All answer choices are eliminated except one.
y = 4x² +2x -4
There are other ways to get the answer. One of them is to use the quadratic regression function of a spreadsheet or graphing calculator. The one attached shows the points are matched by the equation ...
y = 4x² +2x -4 . . . . . as above

A side of the triangle below has been extended to form an exterior angle of 165º. Find
the value of x.
Answers
Answer:
x = 120°
Step-by-step explanation:
the 165 degree obtuse angle forms a straight line with the upper left angle inside the triangle, therefore this angle measures 15 degrees
we know two of the three angle measures so we add all three together to find the unknown angle
x + 15 + 45 = 180
x + 60 = 180
x = 120°

Women 30
Men 50

68
(a) What percentage of the adults are women?
(b) What percentage of the adults prefer TV?
Answers
Answer:
41% of adults are women.
60% of adults prefer TV.
Step-by-step explanation:
Women 30 Newspaper 52 TV 82 In Total so the percentage would be 82 out of 200 which would be 41 therefore 41% of adults are women.
TV scores 52 + 68 = 120 therefore 120 out 200 is the percentage of the adults that prefer TV 60 therefore 60% of the adults prefer TV.
The percentage of the adults prefer TV is 60%.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, a group of 200 adults were asked whether they prefer getting their news from newspapers or from TV.
Here,
Newspapers TV
Women 30 52
Men 50 68
Number of women =30+52
= 82
a) Percentage of the adults are women
= 82/200 ×100
= 41%
b) Percentage of the adults prefer TV
Number of adults watch TV = 52+68
= 120
Here, 120/200 ×100
= 60%
Therefore, the percentage of the adults prefer TV is 60%.

i have most important question what is 2+2 ?
Answers
Answer:
4
Step-by-step explanation:
Answer:
When I look at -2^2 I see two operations, a negation and a power (square). The convention in mathematical expressions is that powers are performed before negations (also before additions, multiplications and divisions) so to evaluate -2^2 you first square the 2 to get 4 and then apply the negation to arrive at -4.
With (-2)^2 the parentheses tell you to consider -2 as a single quantity and square it so (-2)^2 = (-2) × (-2) = 4.

Given the triangle that has two equal angles, and that you'll have to prove that the triangle also has two equal sides.
Using the Converse of Isoceles Triangle Theorem, where it states that if a triangle has two congruent angles < PQR ≅ < PRQ, for which opposite sides of those angles are congruent:
The opposite side of <PQR is line PR.The opposite side of <PRQ is line PQ.Additionally, connecting point P to point X along the line QR such that PX ⊥ QR, divides △PQR into two symmetrical sections, where points Q and R are equidistant from point X.

Jaxon borrowed some money from his friend in order to help buy a new video game system. Jaxon agreed to pay the friend back some amount every week until his loan was paid off. Let L represent the amount Jaxon owes his friend after tt weeks. A graph of L is shown below. Write an equation for L then state the x-intercept of the graph and determine its interpretation in the context of the problem.
Answers
Answer:
L = -2t + 10, (5,0) the interpretation of the x-intercept in the context of the problem is the week that Jaxon owes no more money
Step-by-step explanation:
so we have L=mt+b with m being the slop and b being the y-intercept. the y-intercept is found by looking at what L is when t=0. when t=0, L=10 so b=10. now we have L=mt + 10. to find slop figure out rise/run. every 1 increase in t, L decreases 2 units. this is -2/1 or -2 so m=-2. so the graph is L = -2t + 10
the x- intercept is the t value when L=0, looking at the graph, when L=0, t=5, so the x-intercept is at (5,0)

Which of the following describes the parabola with the equation y = x2 + 2x + 1?
A. The axis of symmetry is x = −1 and the vertex is (−1, 0).
B. The axis of symmetry is x = 0 and the vertex is (0, 1).
C. The axis of symmetry is x = 1 and the vertex is (1, 4).
D. The axis of symmetry is x = 1 and the vertex is (1, 2).
Answers
Answer:
The answer is A. The axis of symmetry is x= -1 and the vertex is (-1,0)
Step-by-step explanation:
Answer: x=1
A. The axis of symmetry is x = −1 and the vertex is (−1, 0).
Step-by-step explanation: graph{x^2+2x+1 [-10, 10, -5, 5]}
Explanation:
This is a quadratic equation so it makes a Parabola on a graph.
Information:
x-intercept: (1,0)
y-intercept: (0,1)
vertex: (1,0)
line of symmetry: x=1
...............................................................................................................................................
The answer is option a via completing the square
y= x^2+2x+1
y= (x+1)^2+1
so it will have an aos of -1 and a vertex of (-1,0)
...............................................................................................................................................
it will have an aos of -1 and a vertex of (-1,0)

Use logarithms to find the exact solution for 7(17^−9)−7=49.
Answers
EXPLANATION:
1. Apply logarithm to both sides of the
equation. If one of the terms has base 10,
use common logarithm, otherwise, use
natural logarithm
2. Use the different properties of logarithms
to solve for the variable.

Step-by-step explanation:
(5x² + 3x + 2)² =
(5x² + 3x + 2)(5x² + 3x + 2) =
5x²(5x² + 3x + 2) + 3x(5x² + 3x + 2) + 2(5x² + 3x + 2) =
