Answer:
I'm not sure what you're asking if P (A) = 0.75 P(A) is equal to 0.75
Can someone help me please
Answer:
A = 2x² + x - 45
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = length × breadth , thus
A = (2x - 9)(x + 5) ← expand using FOIL
= 2x² + 10x - 9x - 45 ← collect like terms
= 2x² + x - 45
please help me it would help a lot

The function f(x) = |x| is shifted to the left 3 units and down 2 units to make the function g(x) . Write the equation g(x) that illustrates this change.
Answer:
g(x) = |x+3|-2
Step-by-step explanation:
to move horizontally replace each x with (x ± c)
if you move it to the right, you need x - c
if you move it to the left , you need x + c
so , since we are moving 3 units to the left, we replace the x with x+3
g(x) = |x+3|-2

The point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2). What are the coordinates of P'? P'(1, 2) P'(1, 1) P'(1, –3) P'(4, 4)
Answer:
(1, -3)
Step-by-step explanation:
If the point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).
To get the coordinate of P', we will replace x as 6 and y as -1 in the translation given as shown
Coordinate of P' = (6 -5, -1, -2)
Coordinate of P' = (1, -3)
hence the coordinate of P' is (1, -3)
Answer:
p'(1 -3)

4. 6
5.-12
Step-by-step explanation:
im not really sure how to explain it to you but the first one that were positive numbers you can just subtract them and get the answer which i gave the forst five to you and when you are this is just an example of the adding the negative numbers 4. -15 + n = -9 you can subtract it and you'll get -15 - (-9) = -6
but if you put negative six it's gonna be the wrong answer sooo you just switch it to a positive number 6 because if you put -15 + (-6) = -21 and when its like this -15 + n = -9 the answer is smaller that the bigger number sooo the only right thing to do it put the positive 6
i hope i got you understanding it a little more if i didnt im soory i tried but the 5 answers i gave you correct

You deposit $300 dollars in a savings account the account earns 10% simple interest per year whats the interest after 8 years
Answer:
$240
Step-by-step explanation:
Given data
Principal= $300
Rate= 10%
Time= 8 years
We know that the expression for the simple interest is given as
SI= PRT/100
Substitute
SI= 300*10*8/100
SI= 24000/100
SI= $240
Hence the interest is $240

Gross profit of Inner Spark's company amounted to Php275,000. Net Sales is Php400,000 compute for cost of goods sold?
Answer:Cost of goods sold =Php125,000
Step-by-step explanation:
Profit = Cost Price-Selling Price
Also we know that
Gross Profit = Net Sales– Cost of Goods Sold
Php275,000=Php400,000– Cost of Goods Sold
Cost of Goods Sold=Php400,000-Php275,000=Php125,000
You're a quality control manager in a fruit juice company. You want to choose
a sample size for a quality check on the cans used to package the juice. From
a batch of 30,000 cans, you want a sample size that will allow you to closely
approximate the population parameters for the entire batch. Which sample
size will most likely produce the least variability among different samples?
Answer:
246.
Step-by-step explanation:
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
b) The minimum sample size to achieve this is 246.
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
So it is z with a pvalue of , so
Now, find the margin of error M as such
In which is the standard deviation of the population(square root of the variance) and n is the size of the sample. So in this question,
The lower end of the interval is the sample mean subtracted by M. So it is 99 - 0.78 = 98.22
The upper end of the interval is the sample mean added to M. So it is 99 + 0.78 = 99.78.
a) The 95% confidence level two-tail confidence interval for the mean value of the key index of this batch is between 98.22 and 99.78
(b) (5 points) If we want the sampling error to be no greater than 0.5, what is the minimum sample size to achieve this based on the same confidence level with part (a)
We need a sample size of n
n is found when
Then
Rounding up
The minimum sample size to achieve this is 246.
