A factory makes memory cards in batches of 4000. For testing purposes, 150 memory cards are selected at random from each batch. Of this sample, 9 memory cards are found to be broken. About how many memory cards in the batch are likely to be broken in all?
Answer:
I think about 27 memory cards.
Step-by-step explanation:
4,000 divided by 150 = 26.6666666667

-2x-3y+z=-6
x=y-z=5

Step by Step Solution:

System of Linear Equations entered :
[1] -2y-3y+z=-6
[2] x+y-z=5
[3] 7x+8y-6z=31
Equations Simplified or Rearranged :
[1] -5y + z = -6
[2] y - z + x = 5
[3] 8y - 6z + 7x = 31
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -y + z + 5
// Plug this in for variable x in equation [3]
[3] 8y - 6z + 7•(-y +z +5) = 31
[3] y + z = -4
// Solve equation [3] for the variable z
[3] z = -y - 4
// Plug this in for variable z in equation [1]
[1] -5y + (-y -4) = -6
[1] -6y = -2
// Solve equation [1] for the variable y
[1] 6y = 2
[1] y = 1/3
// By now we know this much :
y = 1/3
z = -y-4
x = -y+z+5
// Use the y value to solve for z
z = -(1/3)-4 = -13/3
// Use the y and z values to solve for x
x = -(1/3)+(-13/3)+5 = 1/3
Solution :
{y,z,x} = {1/3,-13/3,1/3}

Answer:
2) [tex]\frac{1}{\sqrt[6]m^{5}}[/tex]
Step-by-step explanation:
As per the laws of indices:
[tex]\frac{x^{a} }{x^{b} } = x^{a - b} \\\\and \\ \\(x^{a})^b = x^{ab}[/tex]
Therefore:
2-(1/3) = 5/3
So m ^(5/3)
5/3 multiplied by -1/2 = -5/6
so m^(-5/6)
Another law of indices:
[tex]x^{\frac{a}{y} } = \sqrt[y]{x^{a} }[/tex] and when there is something raised to a negative fraction do the reciprocal.

the area of a circle is 144 π cm2 what is the diameter of the circle
Step-by-step explanation:
Area = pi × r²
144 pi cm² = pi × r²
144 pi ÷ pi = r 2
root 144 = r
12 cm = r
diameter = 2r = 2(12) = 24 cm

Which graph represents f(x) = -2x^4
Answer:
Top right
Step-by-step explanation:
Because it is negative and that is the typical shape for x^4 functions
The graph represents the given function f(x) is attached below
Top right option graph is correct
Given :
The equation of a graph is given by
[tex]f(x)=-2x^4[/tex]
Lets look at the end behavior of the given function f(x)
The leading coefficient is negative that is -2
The highest exponent is 4 that is the degree is even
When the leading coefficient is negative and degree is even then the graph goes down on both sides
As x-> ∞, f(x)-> -∞
As x-> -∞, f(x)-> -∞
So , the graph on the top right is correct

The lengths of the ſides of a triangle are 2x,x+4, and 13 inches. If the perimeter of the
Triangle is 35 inches, what is the value of x?
Please show work if possible! Will mark brainliest!
Answer:
Perimeter = A + B + C
Perimeter = 35
A = 2x
B = x+4
C = 13
35 = A + B + C
Step-by-step explanation:
35=2X+X+4+13
SUBTRACT 17 FROM EACH SIDE
18+3X
DIVIDE EACH SIDE BY THREE
X=6

What are the properties used to solve 4(x+3)=20
Answer:
Multiproperty
Step-by-step explanation:
To solve this problem, we use different properties to arrive at our answer.
Given expression;
4(x + 3) = 20;
First we use the distributive property to expand;
4x + 12 = 20
Now use subtraction property by adding (-12) to both sides;
4x + 12 + (-12) = 20 + (-12)
4x = 8
you can now divide by 4,
x = 2

The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.
To calculate 6 divided by 20, you simply perform the division operation. Divide the numerator (6) by the denominator (20):
6 ÷ 20 = 0.3
The result of 6 divided by 20 is 0.3. This means that if you divide 6 into 20 equal parts, each part will be 0.3.
In decimal form, the fraction 6/20 is equivalent to 0.3. Decimal notation is useful when dealing with fractions that don't easily simplify into whole numbers. In this case, the division results in a decimal less than 1, representing a fraction that is less than a whole. The fraction 6/20 can also be simplified to 3/10, which is the same as 0.3 in decimal form.

EASY QUESTION JUST NEED SECOND OPINION WILL GIVE BRAINLIEST
Answer:I think that what you put is correct but I honestly have no idea. Sorry.
Step-by-step explanation:
Your friend states that he has quarters and dimes in his pocket that total to $5.00. He
also states that there are 6 more quarters than dimes. If there are 26 coins altogether,
how many quarters and dimes are there?
Need help!!
Answer: There are 16 quarters and 10 dimes.
Step-by-step explanation:
Let x = Number of quarters
y= Number of dimes.
As per given,
x+y = 26 (i)
x= y+6 (ii), substitute this in (i), we get
y+6+y= 26
⇒2y+6=26
⇒ 2y = 26-6=20
⇒ 2y =20
⇒ y =10 [Divide both sides by 2]
Put this in (ii), x= 10+6 =16
So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .
