Answer:
∠w = 50°
∠y = 130°
Step-by-step explanation:
Angles ∠w and ∠y are supplementary angles, which means their sum is 180.
4x + 6 + 12x - 2 = 180
Add like terms16x + 4 = 180
Subtract 4 from both sides16x = 176
Divide both sides by 16x = 11
To find the angle measures replace x with 11
∠w = 4x + 6
∠w = 4*11 + 6
∠w = 50°
Now, ∠y
∠y = 12x - 2
∠y = 12*11 - 2
∠y = 130°
Use this pattern when a binomial
can be written as the square of
one number minus the square of
another number.
4x² - 49 = (2x-7)(2x + 7)
a² + 2ab + b² = (a + b)²
The square of a binomial, when the binomials are subtracted, is defined as follows:
(a - b)² = a² - 2ab + b².
How to obtain the square of a binomial?When the two binomials are added, the square is given as follows:
(a + b)².
Expanding the square, we have that:
(a + b)² = (a + b) x (a + b).
(a + b)² = a² + ab + ab + b².
(a + b)² = a² + 2ab + b².
Which is the result presented in this problem.
Now, when the binomial has a minus sign, involving a subtraction, the pattern is obtained as follows:
(a - b)² = (a - b) x (a - b).
(a - b)² = a² - ab - ab + b².
(a - b)² = a² - 2ab + b².

which is a better value? 1 pound of apples for 2.15 or 3 pounds of apples for 5.76
Answer:
From what i've gotten on another answer on brainl It might be 3 pounds of apples for 5.76. On another question i've resarched i've also gotten $7.91.
Step-by-step explanation:
Sorry if none of these answers have helped you.
Answer:
The 2nd offer - 3 pounds of apples for 5.76
Step-by-step explanation:
1. Find the unit price for the 1st offer.
The unit price is 1 pound of apples for $2.15. <-- given information
2. Find the unit price for the 2nd offer.
We can set up a proportion to find the unit price.
3 pounds / $5.76 = 1 pound / $x
Let x = how much 1 pound of apples are for the 2nd offer
Cross multiply
3 · x = 5.76 · 1
Simplify
3x = 5.76
Divide both sides by 3 to isolate x
x = 1.92 = $1.92 for a pound of apples (2nd offer)
3. Compare the two offers' unit prices.
$2.15 <-- 1st offer
$1.92 <-- 2nd offer
The second offer is the better value because it costs less for each pound of apple.

What is the relationship between 7.0/10^2 and 7.0/10^3
\(7/10^2\) is ten times \(7/10^3\) or \(7/10^3\) is one-tenth of \(7/10^2\).
\(10^2\) and \(10^3\) are written in the exponent form.
Exponent
Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
We are given two numbers \(7/10^2\) and \(7/10^3\).
We have to find the relationship between the two given numbers.
We know that,
\(7/10^2\) can be written as 7/100 and \(7/10^3\) can be written as 7/1000.
We can write,
7/1000 = (7/100) *(1/10)
Hence, 7/1000 is one-tenth of 7/100.
Also, we can write,
7/100 = (7/1000)*10
Hence, 7/100 is ten times 7/1000.

2. The dilation of triangle ABC preserves angles but not side lengths.
Hence the correct options are, respectively, C and B.
A translation involves shift left, shift right, shift down, or shift up, meaning that just the coordinates of the figure change, not the angles or the side lengths,
1. The translation of triangle ABC preserves side lengths and angles.
For a dilation, the coordinates of the vertices are multiplied by a constant, hence the side lengths change while the angles remain constant, thus:

Step-by-step explanation:
Without using calculus, you can still estimate the local maximum and minimum points of a function from a graph by looking for the highest and lowest points on the graph in a particular interval. Here are the steps to follow:
1. Determine the interval of interest. Look at the x-axis of the graph and identify the interval where you want to find the local maximum and minimum points.
2. Look for the highest and lowest points on the graph in the interval of interest. Identify the highest point on the graph and mark it as a local maximum. Similarly, identify the lowest point on the graph and mark it as a local minimum.
3. Check for any other potential local maximum or minimum points. Look for any other points on the graph that are higher or lower than the neighboring points. These could be potential local maximum or minimum points.
4. Verify your findings. Once you have identified potential local maximum and minimum points, check them by drawing tangents to the curve at those points. If the tangent is horizontal at the point, then it is a local maximum or minimum point. If the tangent is not horizontal, then it is not a local maximum or minimum point.
5. Note that this method only provides an estimate of the local maximum and minimum points, and it may not be accurate. Calculus provides a more precise method for finding local maximum and minimum points.

Referring to Exercise 7.13, suppose that the effects of copper on a second species (say, species B) of fish show the variance of ln(LC50) measurements to be .8. If the population means of ln(LC50) for the two species are equal, find the probability that, with random samples of ten measurements from each species, the sample mean for species A exceeds the sample mean for species B by at least 1 unit.
Reference
The Environmental Protection Agency is concerned with the problem of setting criteria for the amounts of certain toxic chemicals to be allowed in freshwater lakes and rivers. A common measure of toxicity for any pollutant is the concentration of the pollutant that will kill half of the test species in a given amount of time (usually 96 hours for fish species). This measure is called LC50 (lethal concentration killing 50% of the test species). In many studies, the values contained in the natural logarithm of LC50 measurements are normally distributed, and, hence, the analysis is based on ln(LC50) data. Studies of the effects of copper on a certain species of fish (say, species A) show the variance of ln(LC50) measurements to be around .4 with concentration measurements in milligrams per liter. If n = 10 studies on LC50 for copper are to be completed, find the probability that the sample mean of ln(LC50) will differ from the true population mean by no more than .5.
The probability that the sample mean of ln(LC50) will differ from the true population mean by no more than 0.5 is 0.0019.
The concept of independent random variables is very similar to independent events. Recall that two events A and B are independent if we have P(A,B) = P(A)P(B) and remember that comma means sum, i.e.
P(A, B)=P( A and B)=P (A∩B).
Similarly, we have the following definition for independent discrete random variables.
Assuming 'X' and 'Y' are independent random samples
X : mean value = , variance = 0.4 /10 = 0.04
Y : mean value = , variance = 0.8/10 = 0.08
since the values are independent
V [ X - Y ] = V [ X ] + V [Y ] = 0.04 + 0.08 = 0.12
Now,
The probability that the sample mean for species A exceeds the sample mean for species B by at least 1 unit
\(P(X-Y\geq 1) = P{ \frac{(X-Y)-(U_1-U_2)}{\sqrt{V(X-Y} } \geq \frac{1-0}{\sqrt{0.12} }\)
⇒ P{Z ≥ 2.8858}
⇒ 1 -P{Z≤ 2.8858} = 1 - 0.9981
⇒ P{X-Y≥ 1} = 0.0019.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
