Create and solve a quadratic equation that has 1 real solution
Answer:
x^2 - 4x + 4 = 0
x = 2
Step-by-step explanation:
(x - 2)(x - 2) = 0
x^2 - 2x - 2x + 4 = 0
x^2 - 4x + 4 = 0
The equation is:
x^2 - 4x + 4 = 0
It is a quadratic equation because of the x^2 term.
Now we solve it by factoring.
x^2 - 4x + 4 = 0
(x - 2)(x - 2) = 0
x - 2 = 0 or x - 2 = 0
x = 2 or x = 2
The only solution is x = 2.
Each big square below represents one whole.
Answer:
[tex]51.5%[/tex]%
Step-by-step explanation:
We can see that each big square is made up of 10 x 10 = 100 small squares.
And we have one whole big square, plus 3 small squares shaded.
So we have 103 shaded squares out of 200.
Therefore percentage is [tex]103 / 200 * 100[/tex] = [tex]51.5%[/tex]%
Answer:
103%
Step-by-step explanation:
if you have 1 100 shaded thats 100% and the 3 on the other representes 3% so 100 plus 3 equals 103

The ratio of the number of boys and girls in a college is 6 : 8. If the percentage increase in the number of boys and girls be 20% and 10% respectively, what will be the new ratio.
Answer:
Let the initial number of boys and girls be 600 and 800 respectively, so that
(no. of boys) : (no. of girls) = 6:8.
Final number of boys (Fb) = 600+ 20% of 600 = 720
Final number of girls(Fg) = 800+ 10% of 800 = 880
The new ratio = Fb / Fg = 720 / 880 = 9/11 = 9:11
So, the new ratio will be 9 : 11

please find the complete question which is defined in the attached file.
Given value:
[tex]\to p = 0.42 \\\\\to q = 1 - p[/tex]
[tex]= 0.58[/tex]
[tex]\to n = 400\\\\\to x = 150 \\\\\to P = \frac{X}{n}\\[/tex]

When:
[tex]\to P(P>0.375)\\\\[/tex]
[tex]=P(\frac{P-p}{\sqrt{ \frac{pq}{n}}}>\frac{0.375-0.42}{\sqrt{\frac{0.42 \times 0.58}{400}}})[/tex]

Find the equation of a line that passes through the points (1, 2) and (5,8).
1: y= 3/2 + 1/2
2: y= 3/2 + 1
3: y= 3/2 + 2
Answer:
1: y = 3/2 + 1/2
Step-by-step explanation:
y1 -y2/x1 - x2
8-2 / 5-1
6/4 = 3/2
y-2=3/2(x-1)
y-2=3/2x - 3/2
y-2 +2= 3/2x - 3/2 +2
y=3/2x + 1/2

Determine whether the equation below has a one solutions, no solutions, or an infinite number of solutions. Afterwards, determine two values of xx that support your conclusion. x=x-5
Answer:
no solution
Step-by-step explanation:
X cannot equal itself minus 5, in the same way if we replace it by let's say, 6...
6 does not equal 6-5 (1)........ and by the way in this specific equation 6 is just an example it does not matter what you replace it with, x can never = x-5
