Find the coordinates of the midpoint of segment AB with endpoints A(-2,3) and B(5,-2)

Answer:

40°

Step-by-step explanation:

The measure of the right angle is 90°.

The measures of the angles 10° and 2x add up to the measure of the right angle.

2x + 10° = 90°

2x = 80°

x = 40°

Now verify the options.

Correct choices are C, D, E, F, G.

Answer:

\(-1 < x \leq 4\)

C, D, E, F, G

Step-by-step explanation:

Given compound inequality:

\(-1 \leq 3-x < 4\)

If  a ≤ u < b  then a ≤ u  and u < b:

\(\implies -1 \leq 3-x \;\; \textsf{and} \;\; 3-x < 4\)

Solve each inequality:

\(\begin{aligned}\underline{\sf Case \; 1}\\-1& \leq 3-x\\x-1 & \leq 3\\x&\leq 4\end{aligned}\)           \(\begin{aligned}\underline{\sf Case \; 2}\\3-x& < 4\\-x & < 1\\x& > -1\end{aligned}\)

Combine the intervals:

\(-1 < x \leq 4\)

Therefore, the values that are solutions to the compound inequality from the given answer options are:

The dimensions of the rectangular play yard are 30 feet by 18 feet.

Let's assume that the length of the rectangular play yard is L and the width is W.

The perimeter of a rectangle is given by the formula: P = 2L + 2W.

According to the problem, the Browns installed 96 feet of fencing, so we have:

2L + 2W = 96 (Equation 1)

The area of a rectangle is given by the formula: A = L * W.

According to the problem, the area of the play yard is 540 square feet, so we have:

L * W = 540 (Equation 2)

To solve this system of equations, we can use substitution or elimination. Let's use substitution:

From Equation 2, we can isolate L:

L = 540 / W

Now substitute this expression for L in Equation 1:

2(540 / W) + 2W = 96

Multiply through by W to eliminate the fraction:

\(2(540) + 2W^2 = 96W\\1080 + 2W^2 = 96W\)

Rearrange the equation:

\(2W^2 - 96W + 1080 = 0\)

Divide through by 2 to simplify:

\(W^2 - 48W + 540 = 0\)

Now we can solve this quadratic equation to find the values of W, which represents the width of the play yard. Once we have the value of W, we can substitute it back into Equation 2 to find the corresponding length, L.

Using the quadratic formula:

W = (-b ± \(\sqrt{(b^2 - 4ac)}\)) / (2a)

For the equation \(W^2 - 48W + 540 = 0,\) we have a = 1, b = -48, and c = 540.

Plugging these values into the quadratic formula, we get:

W = (-(-48) ± √\(\sqrt{((-48)^2 - 4(1)(540))}\)) / (2(1))

= (48 ± \(\sqrt{(2304 - 2160)}\)) / 2

= (48 ± \(\sqrt{144}\)) / 2

= (48 ± 12) / 2

So, we have two possible values for W:

W1 = (48 + 12) / 2 = 60 / 2 = 30

W2 = (48 - 12) / 2 = 36 / 2 = 18

Now substitute these values of W back into Equation 2 to find the corresponding lengths:

For W = 30:

L = 540 / 30 = 18

For W = 18:

L = 540 / 18 = 30

Therefore, the dimensions of the rectangular play yard are 30 feet by 18 feet.

The ratio of a:b in 8a + 3b = 5a + 7b is 4:3.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are equal to each other. For example, if there are 2 boys and 6 girls, you can write the ratio as: 1 : 3 (for every boy there are 3 girls).

Ratios compare two numbers obtained by dividing. If one data point (A) is compared to another data point (B), it is expressed as A/B. It means that we are partitioning information A from information B. For example, if A is five and B is 10, your ratio would be 5/10, or 1/2.

For above information,

8a + 3b = 5a + 7b

8a-5a = 7b- 3b

3a= 4b

So, a/b= 4/3

a:b  is 4:3

Thus, the ratio of a:b in 8a + 3b = 5a + 7b is 4:3.

There would be 876 legs.

Step-by-step explanation:

To do it you could first find how many legs there are on one farm. SO you would take the 6 cats in one barrel. Then times it by the 6 kittens each of them have. That's the number of cats. Then times than number by 4 to get the total number of legs in one barrel. Then you add in the two legs of the farmer. Then times that total number by 6 to get all the legs on all six farms.

Answer:

201 eighth graders and 201 + 54 = 255 seventh graders at the middle school.

Step-by-step explanation:

The system of equations representing the situation is:

x + 54 = 456 - x

2x + 54 = 456

2x = 402

x = 201

where x represents the number of eighth graders. So, there are 201 eighth graders and 201 + 54 = 255 seventh graders at the middle school.

A random sample of 8 cars were observed, under normal driving conditions with no police car in sight. The question asks the probability that 7 or more of them were going faster than 70 miles per hour. Let's try to solve this problem step-by-step.Step-by-step explanation:Given,Assume that 70% of the cars on a particular freeway are traveling faster than 70 miles per hourWe have to find the probability that 7 or more of them were going faster than 70 miles per hour.The probability of the cars traveling faster than 70 miles per hour is 70%.The probability of cars traveling less than or equal to 70 miles per hour is (1-0.7) = 0.3 (from the complement rule of probability).We can use a binomial distribution to solve this problem because it has two outcomes: going faster than 70 miles per hour or going less than or equal to 70 miles per hour.P(X = 7) + P(X = 8) = (8C7)(0.7)^7(0.3)^1 + (8C8)(0.7)^8(0.3)^0= 0.4907 ≈ 0.49Therefore, the probability that 7 or more cars were traveling faster than 70 miles per hour is 0.49.

The use and interpretation of an R or s chart are critical when examining an X-bar chart because they provide additional information about the variation within the subgroups. This allows for a more comprehensive analysis of the process and helps identify any issues or sources of variability.

When using an X-bar chart, the focus is on monitoring the process mean or average. However, the X-bar chart alone does not provide information about the variation within the subgroups. This is where the R or s chart comes into play. The R chart measures the range of values within each subgroup, while the s chart measures the standard deviation.
By using an R or s chart alongside the X-bar chart, we can assess the variability within the subgroups and determine if it is stable over time. If the variation within the subgroups is high and unpredictable, it may indicate that the process is out of control or that there are sources of variation that need to be addressed. The R or s chart provides additional insights into the process performance and helps in identifying the presence of special causes of variation.
In summary, the use and interpretation of an R or s chart in conjunction with an X-bar chart allow for a more comprehensive analysis of process variation. This helps in understanding the stability and capability of the process and enables appropriate actions to be taken to improve quality and performance.

The equation a * b = (a, b) * [a, b] is proven to be true for all the given pairs of natural numbers (15, 20), (27, 36), and (54, 72).

a) For the pair (15, 20):
- The greatest common divisor (15, 20) = 5, as 5 is the largest number that divides both 15 and 20.
- The least common multiple [15, 20] = 60, as 60 is the smallest number that is divisible by both 15 and 20.

Now, let's check if the equation holds true:
15 * 20 = 300
(15, 20) * [15, 20] = 5 * 60 = 300

Since the values on both sides of the equation are equal (300), the equation holds true for the pair (15, 20).

- The least common multiple [27, 36] = 108, as 108 is the smallest number that is divisible by both 27 and 36.

Let's check the equation:
27 * 36 = 972
(27, 36) * [27, 36] = 9 * 108 = 972

The equation holds true for the pair (27, 36).

c) For the pair (54, 72):

the oxidation state of the central metal cation (Au) is +3, the coordination number is 2, and the geometry is linear for the complex Na[Au(CN)2].

In the complex Na[Au(CN)2]:

- The oxidation state of the central metal cation, Au, can be determined by considering the charges of the ligands and the overall charge of the complex. Here, the ligands are (CN)2, and each CN ligand has a charge of -1. Since there are two CN ligands, their total charge is -2. The overall charge of the complex, Na[Au(CN)2], is +1 (due to the Na+ cation). Therefore, we can calculate the oxidation state of Au as follows:

  Au + (-2) = +1

  Au = +3

So, the oxidation state of the central metal cation, Au, is +3.

- The coordination number refers to the number of ligands attached to the central metal cation. In this complex, there are two cyanide ligands (CN)2 bonded to the central gold cation (Au), so the coordination number is 2.

- The geometry of the complex can be determined based on the coordination number and the nature of the ligands. In this case, with a coordination number of 2, the geometry is linear.

Therefore, the oxidation state of the central metal cation (Au) is +3, the coordination number is 2, and the geometry is linear for the complex Na[Au(CN)2].
