Answer:
A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective. A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players. The results are given.
948 628 87 4,987 938 468 3,589 298 2,459 2,286
Based on this sample, how many of the MP3 players might the clerk predict would be defective?
The manager would expect
defective players in the shipment.
factor 8x^2+10x-3
plz explain your answer
Answer:
look I have sent you the answer of your question.
This trinomial can be factored as two binomials.
So setup two sets of parenthses.
8x² can be factored as 8x · x or 4x · 2x
and -3 can be factored as +3 · -1, -1· +3, -3 · +1, or +1 ·-3.
If the middle term in the original trinomial is even,
try pairs of even factors first if you have that option.
In this case, we have a 4x and a 2x so let's try those first.
Let's do this with all the factors of -3.
So our first possible answer could be (4x + 3)(2x - 1).
Since the product of the outer terms, -4x, plus the product of the inner, 6x,
doesn't add to our middle term, this pair doesn't work.
Now let's try (4x - 1)(2x + 3).
The product of the outer terms, 12x, plus the product of the inner, -2x,
equals the middle term in our original trinomial, this pair works.
So our answer is (4x - 1)(2x + 3).
x - 62 = 123

[When you read a stem and leaf plot, the lowest number in the stem category, like 3 for example, would be in the tens place. The numbers in the leaf category are the ones places.]
"At least" tells you that anything equal to or higher the number given is relevant to the question. If we count the amount of numbers that are 63 or over, we have:
63, 69, 70, 73, 76, 78.
These are 6 numbers.
Your answer would be 6 companies.

Find the slope ......
The slope for this problem is -4/3.
Step-by-step explanation:
To find the slope, we can look at it as Rise/Run. The rise is how many units up (+) a point is or how many units down (-) a point is from the starting point. The rise is how many units to the left or right a point is from the starting point.
Now that we understand Rise/Run, we can find the slope. If we go from the highest point, or the point farthest to the left in the picture shown, we can see that we need to go four units down to get to the same level as the next point, so we would be moving -4 units away from the point. We can also see the second point is 3 units to left.
With this information, we can now figure out that the slope is -4/3.
Don't hesitate to ask any questions.
Answer:
m =rise/ran=y2-y1/x2-x1
m=slope
(x1, y1)=coordinates of first point in the line
(x2, y2)=coordinates of second point in the line
Step-by-step explanation:
find points.
then use formula & solve.

for which value of k is the set of orders pairs (2,4),(k,6),(4,0) a function?
Answer:
ANSWER:
{(2,4),( 3, 6),(4, 8)} is a function
Given a relation in x and y, we say y is a function of x if for each element x in the domain, there is exactly one value of y in the range. It is a rule of correspondence between two nonempty sets, such that, to each element of the first is called domain, there correspondents one and only one element of the second is called range.
To determine whether it is function or not by using the vertical line test. If the graph passed to Vertical line test it is consider as function. The graph of function defines y as a function of x if no vertical line intersects the graph in more than one point.
The first set of ordered pairs is a function, because no two ordered pairs have the same first coordinates with different second coordinates for example ( -1, 2), ( 1, 0), (2, 1) . The second example is not a function, because it contains the ordered pairs (1,2) and (1,4). the first set is repeated . These have the same first coordinate and different second coordinates.
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain. The range is the resulting y-values we get after substituting all the possible x-values.

Answer:
x = -11 (sorry if this is wrong)
Step-by-step explanation:
5(x+2)-6(2-x)=10(x+1)
5x +10 -12x + 6x = 10x + 10
-1x + 10 = 10x + 10
-10x -10x

A supplementary angle has three angles one being 44.4 another being 7x and another is 8x. I'm having a hard time.
Answer:
x= 9.04°
7x = 63.28°
8x = 72.32
44.4° + 63.28° + 72.32° = 180°
Step-by-step explanation:
The sum of supplementary angles is 180°
Set up an equation with the given information, then solve for x.
44.4 + 7x + 8x = 180
7x +8x = 180-44.4
15x = 135.6 Divide both sides by 15
x = 9.04
Substitute for x and multiply by 7, then 8 to find the measures of the unknown angles.
