Answer:
x+23 = 47
Step-by-step explanation:
Let age of Carlos is x. It is mentioned that the sum of age of Carlos and his mother is 47 years old. Age of Carlos is 23.
We need to find the equation that represents the sum of Carlos' age with his mother.
x+23 = 47 is the required equation.
Also, we can find the age of Carlos as :
x = 47 - 23
= 24 years
Hence, the correct option is (B).
In a standard Normal distribution, what percentage of observations lie above z = 1.65?
Answer:
The percent is 4.9471%
Step-by-step explanation:
Here, we want to find the percentage of observations that lie above z = 1.65
Firstly we find the probability of x < z = 1.65
Hence P ( x > 1.65)
This is obtainable from the standard normal distribution table
The value of P(x > 1.65) = 0.049471
This represents a percentage of 4.9471%
Answer:
4.95/4.9471 is correct

The positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].
Given quadratic equation is:
[tex]-x^{2} +2x+1=0[/tex]
What is the general form of a quadratic equation?The general form of a quadratic equation is [tex]ax^{2} +bx+c=0[/tex] and [tex]a\neq 0[/tex].
On comparing with general form of quadratic equation
a = -1
b = 2
c = 1
So, from the Shreedharacharya formula,
[tex]x = \frac{-b+-\sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x = \frac{-2+-\sqrt{2^{2} -4(-1)(1)} }{2*(-1)}[/tex]
[tex]x = 1-\sqrt{2} \\x=1+\sqrt{2}[/tex]
as [tex]x = 1-\sqrt{2}[/tex] is negative
So, the positive solution is [tex]x=1+\sqrt{2}[/tex]
Therefore, the positive solution to the equation [tex]-x^{2} +2x+1=0[/tex] is [tex]x=1+\sqrt{2}[/tex].

Put the following equation of a line into slope-intercept form, simplifying all
fractions
2x + 4y = 16
Answer:
[tex]4y = 16-2x\\y = \frac{16}{4} - \frac{2x}{4}\\ y = \frac{-1x}{2}+4\\y = 0.5x+4[/tex]
Given parameters:
Equation of the straight line;
2x + 4y = 16
The slope intercept form of the equation is y = mx + c
Where m is the slope of the line
y and x are the coordinates
c is the intercept
So, the problem is to write the given equation in form of y = mx + c;
2x + 4y = 16
4y = 16 - 2x
Divide through by 2;
[tex]\frac{4y}{2}[/tex] = [tex]\frac{16}{2}[/tex] - [tex]\frac{2x}{2}[/tex]
2y = 8 - x
2y = -x + 8
Then divide by 2 all through;
[tex]\frac{2y}{2}[/tex] = [tex]\frac{-x}{2} + \frac{8}{2}[/tex]
y = [tex]\frac{-x}{2} + 4[/tex]
The equation of the line is y = [tex]\frac{-x}{2} + 4[/tex]
Write an equation for the table in the slope intercept form.

GEOMETRY HELP ASAP PLEASE!!!
Answer:
x = 120
z = 21
Step-by-step explanation:
x and 60 are supplementary, so added together they make 180.
x + 60 = 180
subtract 60 from both sides
x = 180 - 60
x = 120
next, x and 4z+36 are equal, so you can make this equation:
x = 4z + 36
substitute x for 120 as established earlier.
120 = 4z + 36
subtract 36 from both sides
120 - 36 = 4z
84 = 4z
divide both sides by 4
84/4 = z
21 = z
Explain, please, and answering
Answer:
86 degrees
Step-by-step explanation:
Alrighty, a simple 180-degree triangle, we can see that the two angles add up to 86, so what would make our angle G1 94 since 180-86 = 94, but we are tasked with finding the other side of that angle, let's call it G2, what should we do?
Since this is a flat 180-degree line, we do it again!
180-94 = 86 degrees
And there ya have it
Though, if you need the technical side, it's because a whole of a triangle is 180 degrees
Given that angles F is 58 and E is 28, we add those two up to find angle EGF. How to find EGF you ask? Simple- 180 degrees (Because it's a triangle) minus 86 (Added angles of E and F), that would equal 94.
Now, we are tasked with finding TGF. We do not have TGF but we have EGF. Learning that, we see the line ET, indicating that we have found ourselves a 180-degree line. What do we do with this line? We use it to calculate TGF with EGF
Since EGF is 94, we take the 180 - 94 to equal 86, and that is how you find TGF
Solve each system by substitution:
3x-6y = 2
4x+3y = -1
from the first equality we have
3x - 6y = 2
3x = 2 + 6y
x = 2/3 + 2y
we replace x by this value in the second equality
4 * (2/3 + 2y) + 3y = -1
8/3 + 2y + 3y = - 1
5y = - 3/3 - 8/3
5y = - 11/3
y = -11/15
and we can get x now :
and x = 2/3 + 2*(-11/15)
x = 2/3 - 22/15
x = 10/15 - 22/15
x = - 12/15
check
3 * (-12/15) - 6 * (-11/15) = -36/15 + 66/15 = 2

Hey there!
Problem A.
((-10)^3 * 6)^3
= ((-10)(-10)(-10) * 6)^3
= (100(-10) * 6)^3
= (-1,000 * 6)^3
= (-6,000)^3
= (-6,000)(-6,000)(-6,000)
= 36,000,000(-6,000)
= 216,000,000,000
Thus, your answer is: 216,000,000,000
Problem B.
(3^2/5)^3
= (3 * 3 / 5)^3
= (9/5)^3
= 9/5(9/5)(9/5)
= 9 * 9 * 9 / 5 * 5 * 5
= 81 * 9 / 25 * 5
= 729 / 125
≈ =5 104 / 125
≈ 5.832
Thus, your answer is:
5.832 , 5 104/125, or 729 / 125
EITHER OF THOSE SHOULD BE CORRECT BECAUSE THEY ARE EQUIVALENT TO EACH EACH OTHER!

A genius society requires an IQ that is in the top 2% of the population in order to join. If an IQ test has a mean of 100 and a standard deviation of 15, which of the following could be used as the minimum qualifying score to join the genius society? 115 130 145 160.
The minimum qualifying score to join the genius society is 130, the correct option is B.
What is the minimum qualifying score?In the top 2%, you have to have an IQ higher than 98% of the population (100% - 2%). This is also known as the 98th percentile.
Given
A genius society requires an IQ that is in the top 2% of the population in order to join.
If an IQ test has a mean of 100 and a standard deviation of 15.
For this problem, you are given the probability and need to determine the raw score.
For the probability, go to the z–table and find the probability that is closest to 0.98. Then look across the row and up the column to determine the z-score.
The closest probability is 0.97982 and that corresponds to a z-score of 2.05.
With a z-score of 2.05, you can use the z formula to compute the raw score.
[tex]\rm z-score=\dfrac{X- mean }{Standard \ deviation}\\\\2.05=\dfrac{x-100}{15}\\\\2.05 \times 15 = x-100\\\\30 +x-100\\\\x=100+30\\\\x = 130[/tex]
Hence, the minimum qualifying score to join the genius society is 130.
