Answer:
1/89
Step-by-step explanation:
Two digit numbers include all numbers from 10 to 99. 99-10 = 89. Therefore the probability that Simon guesses the number correctly on the first try is 1 out of 89 which can be written as 1/89.

The total cost for one year at the state university is $22,500. A student has the following help in covering the costs of school. . • An academic scholarship for $10,000. • Other scholarships and grants for $4,400. Parents pay $1,800, . What is the amount that the student will need to save every month in order to pay off the remaining costs in 10 months?
A) $630
B) $525
C) $1,200
D) $1,440
so her University costs are $22,500
however she gets some help because
◉ academic scholarship pays 10,000 off of that
◉ other scholarships pay 4,400 off of that
◉ and her parents pay 1800 off of that
what's left? well, what's left is 22500 - 10000 - 4400 - 1800 = 6300 bucks.
so for the next 10 months she needs to cover 6300 bucks of her expenses, now 6300 spread over 10 months is 630 a pop.

The solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].
What is completing the square method?Completing the square method is factorizing a quadratic equation, and henceforth finding the roots or zeros of a quadratic polynomial or a quadratic equation.
According to the given question.
We have a quadratic equation
[tex]3x^{2} + 24x - 24 = 0[/tex]
The above quadratic equation can be written as
[tex]3(x^{2} + 8x - 8) = 0[/tex]
[tex]\implies x^{2} + 8x -8= 0[/tex]
Now, we will solve the above equation by completing the square method.
[tex]x^{2} +8x - 8= 0[/tex]
[tex]\implies x^{2} + 2(4x) +(4)^{2} -(4)^{2} -8 = 0[/tex]
[tex]\implies x^{2} + 2(4x) + 16 - 16 -8 = 0[/tex]
[tex]\implies (x+4)^{2} - 24=0[/tex]
[tex]\implies (x+4)^{2} = 24[/tex]
[tex]\implies (x+4)^{2} = 24[/tex]
[tex]\implies (x+4) = \sqrt{24}[/tex]
[tex]\implies x+ 4 = \pm 2\sqrt{6}[/tex]
[tex]\implies x = 2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex]
Hence, the solution of the given quadratic equation by completing the square method are [tex]2\sqrt{6} -4 \ or -2\sqrt{6} -4[/tex].

(8/3,11/3) is the centroid of the given triangle
pls do mention in comment if u need full solution
Answer:
(8/3, 11/3)
Step-by-step explanation:
Formula of the centroid
(x, y) = [(x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3]Points
(-2, 3)(6, 7)(4, 1)Solving :
Centroid = [(6 + 4 - 2)/3, (3 + 7 + 1)/3]Centroid = (8/3, 11/3)given f (x)=x-4/x^2+13x+36 which of the following is true
The function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is a rational function
The simplified expression of the function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is [tex]f(x) =\frac{x - 4}{(x + 9)(x + 4)}[/tex]
How to simplify the function?The function expression is given as:
f(x) =x - 4/x^2 + 13x + 36
Rewrite properly as:
[tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex]
Expand the denominator
[tex]f(x) =\frac{x - 4}{x^2 + 4x + 9x + 36}[/tex]
Factorize the denominator
[tex]f(x) =\frac{x - 4}{x(x + 4) + 9(x + 4)}[/tex]
Factor out x + 9
[tex]f(x) =\frac{x - 4}{(x + 9)(x + 4)}[/tex]
Hence, the simplified expression of the function [tex]f(x) =\frac{x - 4}{x^2 + 13x + 36}[/tex] is

Find an equation for the line that passes through the points (-1,-4) and (5,-2)
Linear equations are typically organized in slope-intercept form:
[tex]y=mx+b[/tex]
m = the slope of the lineb = the y-intercept (the value of y when the line crosses the y-axis)To determine a linear equation in slope-intercept form:
Find the slopePlug the slope into y=mx+bFind the y-interceptPlug the y-intercept into y=mx+bSolving the QuestionWe're given:
The line passes through the points (-1,-4) and (5,-2)First, find the slope of the line (m):
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex] where two points that fall on the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
⇒ Plug in the given points (-1,-4) and (5,-2):
[tex]m=\dfrac{-2-(-4)}{5-(-1)}\\\\m=\dfrac{-2+4}{5+1}\\\\m=\dfrac{2}{6}\\\\m=\dfrac{1}{3}[/tex]
⇒ Therefore, the slope of the line is [tex]\dfrac{1}{3}[/tex]. Plug this into y=mx+b:
[tex]y=\dfrac{1}{3}x+b[/tex]
Now, determine the y-intercept (b):
[tex]y=\dfrac{1}{3}x+b[/tex]
⇒ Plug in one of the points and solve for b:
[tex]-4=\dfrac{1}{3}(-1)+b\\\\-4=-\dfrac{1}{3}+b\\\\-4+\dfrac{1}{3}=b\\\\b=-\dfrac{11}{3}[/tex]
⇒ Therefore, the y-intercept is [tex]-\dfrac{11}{3}[/tex]. Plug this back into our original equation:
[tex]y=\dfrac{1}{3}x-\dfrac{11}{3}[/tex]
Answer[tex]y=\dfrac{1}{3}x-\dfrac{11}{3}[/tex]

Y={2x-1)(x+4)(2x-3)(x-1)
Answer:
Y =4x^4 + 4x^3 − 37x^2 + 41x −12
Step-by-step explanation:
Y = (2x - 1 ) (x + 4) (2x - 3) (x - 1)
Using commutative property we can re-arrange RHS,
Y= (2x - 1) (2x - 3) (x + 4) (x - 1)
Using the property
[(x+a) (x+b) = x^2 + (a+b)*x +ab],
Y =
[(2x)^2 + (-1 - 3)*2x + (-1 )*(-3)] [x^2 + (4 - 1)*x + 4*(-1)]
From here onwards I would recommend u to do the calculation by your own bc I might have made mistakes
in the steps but I got right but still just check yourself if u copy all the steps as it is
Y = (4x^2 -8x + 3) (x^2 + 3x -4)
Y = 4x^4 + 12x^3 - 16x^2 -8x^3 -24x^2 + 32x + 3x^2 + 9x - 12

Raymond caught the football 28 out of 35 times at practice. Predict the number of times he will catch the football during the game if it is thrown to him 20 times.
Answer:
16 times
Step-by-step explanation:
This problem is solved by ratio. Since the ratio of 28 out of 25 times is 4:5, he has to catch the ball 4:5 or 4 of 5 times. You multiply both 5 and 4 by 4, because that's how many times he's gonna catch it. 4 x 4 = 16, so the answer is 16 times.
Answer:
(4/5)^20
Step-by-step explanation:
1) First, write the numbers of times Raymond caught the football out of 35 attempts. This is a necessary step in order to obtain an appropriate operand.
28
35
2) Reduce the fraction to lowest terms. This is an optional step but it simplifies the problem.
28 / 4
35 4
= 4
5
3) Raise the fraction to the 20th power. If the ball is thrown at him 20 times, the probability of him successfully catching the ball must be (4/5)^20.
= (4)^2
(5)
