Step-by-step explanation:
The problem can be written as
Ar = where A = 5×6 matrix. dim(NullA)=1 as all the multiples of Ar=0
are the multiple of one non zero solution.
Since A is 5×6 , A n= 6
rank(A)= n-dim(Nul A)= n-1= 6-1=5
now, imagine A as 5 dimensional subspace of R^5( As A has 5 rows)
Therefore Col(A)= R^5
This means that Ar = b has a solution for every b.

Answer:
The third option
Step-by-step explanation:
If you plug -4 in for x in the first option, you would get 12 + which is 14 and
14 ≠ 5.
If you plug in -4 for the second option you would have -0.75 times -4 which is 3 and 3 plus 8/3 would not give you a whole number so it is not equal to 5.
If you plug in -4 to the third option you would get -4 times -0.75 which is 3 and 3 + 2 = 5. But to check the rest of the numbers you would plug in 0 for x and get -0.75 times 0 is 0 and 0 + 2 = 2.
For the last option, just to eliminate all other options, if you plug in -4 for x you would have 2 times -4 which is -8 and -8 - 0.75 would not be a whole number so it could not be 5.

Answer:
x = √66
Step-by-step explanation:
In a geometry like this, the right triangles are all similar. Then the length of the long side to the hypotenuse is ...
6/x = x/(6+5)
6·11 = x²
x = √66
_____
Additional comment
The relation g=√(ab) gives the geometric mean (g) of the two numbers 'a' and 'b'. In this geometry, there are three geometric mean relationships.
long side = geometric mean(long segment, hypotenuse) . . . x = √(6·11)
short side = geometric mean(short segment, hypotenuse) . . . y = √(5·11)
altitude = geometric mean(long segment, short segment) . . . BD = √(6·5)

La proporción de niños y niñas en la obra escolar es de 5 a 8. Hay 32 niñas que participan en la obra. ¿Cuántos niños participan en la obra escolar?
Answer:
Total children = 52
Step-by-step explanation:
The question says that "The ratio of boys to girls in the school play is 5 to 8. There are 32 girls participating in the play. How many children participate in the school play? "
Let there are 5x boys and 8x girls in a school play.
Total no of girls participating in the play = 32
ATQ,
8x = 32
x = 4
Boys = 5x
= 5(4)
= 20
Total children = boys + girls
= 20 + 32
= 52
Hence, there are 52 children participating in the school play.

Answer:
x=45°
Step-by-step explanation:
Since the angle is acute it's half of a right angle.
Right Angle is 90°
So u divide the right angle By 2 (90°÷2) You would get 45°

[tex](2x+9)(1x+2)=0[/tex]
Answer:
x=-9/2, -2
Step-by-step explanation:
2x+9=0 subtract 9 and divide by 2 to isolate x.
x=-9/2
(writing a 1 in front of the x is unnecessary) x+2=0 subtract 2 to isolate x.
x=-2

However, the water cooler develops a leak during the game, and is losing water at a rate of 4 quarts
per minute.
Part A: Write a function representing the amount of water, w(t), still in the cooler after t minutes.
Part B: how many minutes will it take for the cooler to be empty? The cooler will be empty after___ minutes
Answer:
Part A: w(t)=60-4t
Part B: w(15)=60-60=0
The cooler will be empty after 15 minutes.

Given: x + y = 10.
If x = -21, what is y?
31
11
-31
Answer:
y is 31
Step-by-step explanation:
we need to substitute first
x + y = 10
x= -21 so...
-21 + y = 10
now we need to add 21 on both sides of the equation, we are adding because 21 because we want that 21 gone, and it's the oppisite of subtracting
-21 + 21 + y = 10 + 21
0 + y = 10 + 21
y= 31
Check:
x+y=10
-21 + 31= 10
10 = 10 correct!
Hope this helped!

I dont get this so cant help daughter
1.
We are told that the coordinates of the image are of the formula:
P'(x-2 , y-3) where x and y are the actual points and x-2 and y-3 are the reflections
Finding the coordinates of point A:
We are given that the coordinates of reflection of A are: A'(-4 , 3)
we also know that reflected point follow the formula: P'(x-2 , y-3)
So, the points of A'(-4 , 3) follow the formula P'(x-2 , y-3)
So, their respective x and y coordinates will be equal
Hence,
x - 2 = -4
x = -2 [adding 2 on both sides]
Also,
y - 3 = 3
y = 6 [adding 3 on both sides]
Therefore, the coordinates of A are A(-2,6)
Finding the coordinates of B:
We are given the coordinates of B' are B'(-4 , 2)
So,
x - 2 = -4
x = -2 [adding 2 on both sides]
also,
y-3 = 2
y = 5 [adding 5 on both sides]
Therefore, the coordinates of B are: B(-2,5)
Finding the coordinates of C:
We are given that the coordinates of reflection of C are: C'(-2,3)
Using the general formula given in the question:
x - 2 = -2
x = 0 [adding 2 on both sides]
y - 3 = 3
y = 6 [adding 3 on both sides]
Therefore, the coordinates of C are: C(0,6)
Finally, the coordinates of A, B and C are:
A(-2,6) , B(-2,5) , C(0,6)

Reflecting the pre-image along the x-axis
To reflect along x-axis, we multiply the y-coordinate by -1
Coordinates of the pre-image:

Coordinates of points reflected along the x-axis:
A(-2,-6) , B(-2,-5) , C(0,-6)

Factor -4 out of -8d + 20
Answer:
2d-5
Step-by-step explanation:
Take out or divide everything in the expression by -4
So, (-8d+20) ÷ -4 = 2d-5
To check your answer, multiply:
-4 × (2d-5) = -8d+20
The linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear expression in one variable is:
= -8d + 20
Here d is the variable
Taking common as - 4 from the linear expression:
= -4(2d - 5)
Thus, the linear expression in one variable -8d + 20 can be written as -4(2d - 5) after factoring -4 from it.

A sampling distribution is the probability distribution of _____. Group of answer choices a population parameter a sample statistic an observation that is randomly selected from the population a sample
Answer:
"a Sample Statistic"
Step-by-step explanation:
A sampling distribution is defined as the probability distribution of "a statistic" drawn from a large number of samples gotten from a specific population. In order words, it is a sample statistic.
Thus, the correct answer is "a Sample Statistic"
The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means
Sampling distribution:It is a probability distribution of data mining, which is the process of analyzing larger samples gathered from a given population.
In this, a particular population is the distribution of frequencies of a variety of possible outcomes for a population statistic.
It is the distribution of the probability for a statistic is generated from a large number of samples gathered from a certain population.
Therefore, "The sampling distribution is the probability of a particular report based on random sampling; it displays the most likely values of various sample means".
