what is the sum of -7+5 A1 -12 A2 -2 A3 -1 A4 1 A5 2 A6 12 plz help fast
Answer:
A2 -2
Step-by-step explanation:
Given the mathematical expression;
-7 + 5
To find their sum;
Simplifying a mathematical expression simply means to collect like terms that are having the same variables or constants and combining them, so as to reduce the expression to the lowest possible value.
-7 + 5 = -2
Therefore, the sum of -7 + 5 is equal to -2

Answer:
The functions are:
f(x) = $14.75*x + $2
s(x) = $12.25*x + $17
Both iSpice and Spice Magic charge $90.50 for 6 pounds of paprika.
Step-by-step explanation:
A linear equation has the general shape:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that the function passes through the points: (x₁, y₁) and (x₂, y₂) then the slope is:
a = (y₂ - y₁)/(x₂ - x₁)
Ok, knowing this, let's look at the first table, we need to work with only two points, so let's use the first one (1, $16.75) and the second one (2, $31.50)
Then the slope of the equation is:
a = ($31.50 - $16.75)/(2 - 1) = $14.75
Then the equation is something like:
y = f(x) = $14.75*x + b
To find the value of b, we can use one of the two points. For example, the point (1, $16.75) means that when x = 1, we must have y = $16.75
Replacing these values in the equation we get:
$16.75 = f(1) = $14.75*1 + b
$16.75 - $14.75 = b = $2
Then the function f(x) is:
f(x) = $14.75*x + $2
Now let's go to the other function, again we can choose two points, let's use the first one (1, $29.25) and the third one (3, $53,75).
Then the slope is:
a = ($53.75 - $29.25)/(3 - 1) = $12.25
Then the equation is something like:
y = s(x) = $12.25*x + b
To find the value of b we do the same as before, if we use the first point (1, $29.25) we get:
$29.25 = s(1) = $12.25*1 + b
$29.25 - $12.25 = b = $17
Then this equation is:
y = s(x) = $12.25*x + $17
The two equations are:
f(x) = $14.75*x + $2
s(x) = $12.25*x + $17
b) now we want to find the value x such that the price is the same in both cases, then we need to solve:
f(x) = g(x)
$14.75*x + $2 = $12.25*x + $17
$14.75*x - $12.25*x = $17 - $2
$2.5*x = $15
x = $15/$2.5 = 6
This means that for 6 pounds of paprika the price is the same on both companies, and the price is:
f(6) = g(6) = $14.75*6 + $2 = $90.50

f(z) = (z - 5)(2x + 7) (73 = 3) has zeros at x = -3.5, x=3/7 , x=5 What is the sign of f on the interval 3/7 < x <5?
======================================================
Explanation:
3/7 = 0.42857 approximately
Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2
Plug x = 2 into the f(x) function
f(x) = (x - 5)(2x + 7)(7x-3)
f(2) = (2 - 5)(2*2 + 7)(7*2-3)
f(2) = (2 - 5)(4 + 7)(14-3)
f(2) = (-3)(11)(11)
f(2) = -363
The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.

At that time, the U.S. population was 64% Caucasian, 11% African-American, and 13% Hispanic. What percentage of U.S. residents who used the Internet for e-mail were Hispanic
Answer:
The total percentage of U.S. residents who used the Internet for e-mail were Hispanic was 9.5%
Step-by-step explanation:
Given
In a certain year the % share of American population that was Hispanic was 13%
Out of these 13%, 73% Hispanic used the internet for emails.
Now the total percentage of U.S. residents who used the Internet for e-mail were Hispanic was 0.13 * 0.73 = 0.095 = 9.5%
Jada has d dimes she has more that 30 cents but less than a dollar can d be 10
Answer:
no
Step-by-step explanation:
30 cents < 10 cents/dime × d dimes < 1 dollar × 100 cents/dollar
if d = 10
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
30 cents < 10 cents/dime × 10 dime < 1 dollar × 100 cents/dollar
notice how the units bolded all cancel out, just leaving cents
30 cents < 100 cents is NOT < 100 cents

Question #3 show steps or how you know
Answer: Choice D)
(-1.5, -1) and (0, 1)
=============================================================
Explanation:
Exponents can be a bit clunky if you have too many of them, and if they're nested like this. Writing something like e^(x^2) may seem confusing if you aren't careful. I'm going to use a different notation approach. I'll use "exp" notation instead.
So instead of writing something like e^(x^2), I'll write exp(x^2).
The given derivative is
f ' (x) = exp(x^4-2x^2+1) - 2
and this only applies when -1.5 < x < 1.5
Apply the derivative to both sides and we'll find the second derivative
f ' (x) = exp(x^4-2x^2+1) - 2
f '' (x) = d/dx[ exp(x^4-2x^2+1) - 2 ]
f '' (x) = exp(x^4-2x^2+1)*d/dx[ x^4-2x^2+1 ]
f '' (x) = exp(x^4-2x^2+1)*(4x^3-4x)
f '' (x) = (4x^3-4x)*exp(x^4-2x^2+1)
From here, we need to find the roots of f '' (x).
Set f '' (x) equal to zero and solve to get...
f '' (x) = 0
(4x^3-4x)*exp(x^4-2x^2+1) = 0
4x^3-4x = 0 ..... or .... exp(x^4-2x^2+1) = 0
4x(x^2-1) = 0
4x(x+1)(x-1) = 0
4x = 0 or x+1 = 0 or x-1 = 0
x = 0 or x = -1 or x = 1
Those are the three roots. We ignore the equation exp(x^4-2x^2+1) = 0 because it doesn't have any real number solutions.
---------------------
The three roots of x = 0 or x = -1 or x = 1 represent possible locations of points of inflection (POI). Recall that a POI is where the function changes concavity. To determine if we have a POI or not, we'll need to a sign test.
Draw out a number line. Plot -1, 0, and 1 in that order on it. Pick something to the left of -1 but larger than -1.5, lets say we pick x = -1.2. Plugging this into the second derivative function leads to...
f '' (x) = (4x^3-4x)*exp(x^4-2x^2+1)
f '' (-1.2) = (4(-1.2)^3-4(-1.2))*exp((-1.2)^4-2(-1.2)^2+1)
f '' (-1.2) = -2.563
That value is approximate. The actual value itself doesn't matter. What does matter is the sign of the result. The negative second derivative value tells us we have a concave down region. So we just found that f(x) is concave down for the interval -1.5 < x < -1, which converts to the interval notation (-1.5, -1)
Repeat the process for something between x = -1 and x = 0. I'll pick x = -0.5 and it leads to f '' (-0.5) = 2.63 approximately. The positive result tells us that we have a concave up region. Therefore, -1 < x < 0 is not part of the answer we're after.
Repeat for something between x = 0 and x = 1. I'll pick x = 0.5 and it produces f '' (0.5) = -2.63 approximately. So the region 0 < x < 1 is also concave down. Meaning that the interval notation (0,1) is also part of the answer.
So far we have the interval notation of (-1.5, -1) and (0,1) as part of our solution set.
Lastly, we need to check something to the right of x = 1, but smaller than 1.5; let's go for x = 1.2
You should find that f '' (1.2) = 2.563 which allows us to rule out the region on the interval 1 < x < 1.5
Overall, the final answer is (-1.5, -1) and (0, 1)

Of 600 students sampled, 480 said they hoped to own a house someday. With 99.7% confidence, what is the approximate percentage of the students in the population who hope to own a house someday?
A. 73.5% to 86.5%
B. 75.1% to 84.9%
C. 76.7% to 83.3%
D. 78.4% to 81.6%
Answer:b
Step-by-step explanation: i just answered it
The approximate percentage of the students in the population who hope to own a house someday is 76.7% to 83.3%.
The correct answer is option C.
What is a percentage?The percentage means the required value out of 100.
It is calculated by dividing the required value by the total value and multiplying it by 100.
The percentage change is also calculated using the same method.
In percentage change, we find the difference between the values given.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
To find the approximate percentage of the students in the population who hope to own a house someday with 99.7% confidence,
We need to use the confidence interval formula:
Confidence Interval = Sample proportion ± Margin of error
where the sample proportion is the fraction of the sample who said they hope to own a house someday, and the margin of error reflects the amount of uncertainty in the estimate.
The formula for the margin of error is:
Margin of error = z x (√(p x (1 - p)) /√(n))
where z is the z-score corresponding to the desired level of confidence, p is the sample proportion, and n is the sample size.
In this case,
The sample proportion is 480/600 = 0.8, the sample size is 600, and the level of confidence is 99.7%, which corresponds to a z-score of 3.
Plugging these values into the formula, we get:
Margin of error = 3* x √(0.8 x (1 - 0.8)) / √(600)) = 0.034
So the 99.7% confidence interval is:
0.8 ± 0.034, which is equivalent to (0.766, 0.834)
Converting to percentages, we get:
(0.766 x 100, 0.834 x 100) = (76.6%, 83.4%)
Therefore,
The approximate percentage of the students in the population who hope to own a house someday is 76.7% to 83.3%.
