two opposite angles of a parallelogram (4x-50)^0 and (60 - x)^0
All the angles of the given parallelogram found using the properties of the parallelogram are 38°,38°, 142° and 142°.
What is meant by a parallelogram?
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size. On the same side of the transversal, the interior angles are supplementary. 360 degrees is the sum of all interior angles. The qualities of a parallelogram are shared by the shapes of a square and a rectangle.
Given the two opposite angles of parallelogram as (4x-50)° and
(60 - x)°.
We are asked to find all the angles of the parallelogram.
As said earlier, opposite angles of parallelogram are equal.
So,
4x-50 = 60 - x
5x = 110
x = 22
So the opposite angles are:
4x-50 = 4*22- 50 = 38°
Adjacent angles are supplementary. So,
38 + y = 180
y = 142°
Sum of all angles of parallelogram should be 360°.
38+38+142+142 = 360°.
Therefore all the angles of the parallelogram are 38°,38°, 142° and 142°.

a student measures the mass of a rock three times using the same properly calibrated analog (not digital) balance and gets slightly different values: 22.46g, 22.42g, and 22.44g. what type of error may have occurred here (systematic and/or random)? how would the student minimize the impact of this error during data analysis?
The errors that may have occurred in the student's measurements are random errors. These types of errors can arise from various sources, such as slight variations in measurement techniques or environmental factors.
Since the measured values are slightly different, it suggests that random errors affected the measurements rather than systematic errors, which would result in consistently incorrect measurements.
To minimize the impact of random errors during data analysis, the student can calculate the average of the three measured values. The average value can serve as the best estimate of the true value of the mass of the rock. Additionally, the student can calculate the standard deviation of the measured values to determine the precision of the measurements. The smaller the standard deviation, the more precise the measurements.
The student can further minimize random errors by taking multiple measurements and averaging them to obtain a more accurate value. Additionally, using a digital balance instead of an analog one may reduce random errors as digital balances have greater precision and accuracy.
It is also important for the student to use proper measurement techniques such as ensuring that the balance is calibrated and zeroed correctly before each measurement. The student should also avoid applying excessive force on the balance and ensure that the rock is stable and level during measurement.

a group of 9 people is going to be formed into committees of 4, 3, and 2 people. how many committees can be formed if
There are 20 different combinations of committees that can be formed since no person can serve on more than one committee.
In order to form committees of 4, 3, and 2 people, we must first determine how many combinations are possible. There are 9 people in total, so the first committee must consist of 4 people. That leaves 5 people. The second committee must consist of 3 people, leaving 2 people for the final committee. To calculate the total number of combinations, we must multiply the number of choices for each committee. For the first committee, there are 9C4 combinations, for the second committee there are 5C3 combinations, and for the third committee there are 2C2 combinations. Multiplying these together, we obtain 9C4 x 5C3 x 2C2 = 20 combinations. Therefore, there are 20 different combinations of committees that can be formed since no person can serve on more than one committee.

The measurements required to provide a 95% confidence interval in the true mean to within plus minus 0.28v are 2 measurements and they are 1.24v and 1.8v .
Given that, based on 51 measurements of time-dependent electrical signal, the standard deviation is 1.52 v
The 95 confidence interval in its true mean value is 0.28 and the measurements required to provide a 95% confidence interval in the true mean to within plus minus 0.28v are 2 measurements and they are 1.24v and 1.8v
A Standard Deviation of the R.V.(random variable), a sample, and a statistical population, the data set, or the probability distribution is the square root of the its variance
A True Mean refers to a population mean. It actually would not have a population mean, because since it is the either impossible to get and probably the time consuming and too much expensive to get it.
Therefore, the 95 confidence interval in its true mean value is 0.28 and the measurements required to provide a 95% confidence interval in the true mean to within plus minus 0.28v are 2 measurements and they are 1.24v and 1.8v

Answer:
6 is not the solution. 7 is the solution.
Step-by-step explanation:
5(x -3) = x + 13 Substitute 6 for x
5(6 -3) = 6 + 13
5(3) = 19
15 ≠ 19
6 is not a solution because it results in a false statement. The two sides do not equal each other.
5(x - 3) = x + 13 Distribute the 5
5x -15 = x + 13 Subtract x from both sides
5x - x - 15 = x - x + 13
4x - 15 = 13 Add 15 to both sides
4x - 15 + 15 = 15 + 13
4x = 28 Divide both sides by 4
x = 7
7 is the solution to the equaion.
given the set [1,2,3,5,8,13,21,34,55}, how many integers between 3 and 89 cannot be written as the sum of excatly two elements of the set?
The final count of integers between 3 and 89 that cannot be written as the sum of exactly two elements of the set is 39.
To determine the number of integers between 3 and 89 that cannot be written as the sum of exactly two elements of the set {1, 2, 3, 5, 8, 13, 21, 34, 55}, we can use a process of elimination.
First, we can list all the possible sums of two distinct elements of the set. This gives us a total of 28 sums.
Next, we can identify all the integers between 3 and 89 that can be expressed as the sum of two distinct elements of the set. We can do this by checking each integer between 3 and 89 to see if it can be written as a sum of two elements of the set. If an integer can be written as a sum of two elements of the set, we can cross it off the list.
After eliminating all the integers that can be written as a sum of two elements of the set, we are left with the integers that cannot be expressed as such.
In summary, we can determine the number of integers between 3 and 89 that cannot be written as the sum of exactly two elements of the set by listing all possible sums, identifying the integers that can be expressed as such sums, and eliminating them from the list.
The remaining integers are those that cannot be expressed as the sum of exactly two elements of the set.

A bag contains 950 marbles. Some are red and some are blue. A student reached into the bag
and pulled out a random sample of 20 marbles. He recorded that 11 were blue and 9 were
red. If this is a representative sample, about how many marbles out of 950 are blue?
Answer: The number of blue marbles in the sample is 11, so the proportion of blue marbles in the sample is 11/20. If the sample is representative, we can use this proportion to estimate the proportion of blue marbles in the whole bag of 950 marbles. So, our estimate of the number of blue marbles in the whole bag is:
950 * (11/20) = 477.5
So, we can estimate that about 478 marbles out of 950 are blue.
Step-by-step explanation:
A box of cereal states that there are calories in a 3/4
-cup serving. What is the unit rate for calories per cup? How many calories are there in 3cups of the cereal?
120 calories make up one cup amount of calories. Three cups of the cereal have 360 calories in them.
1. Determine how many calories are in a cup: 120 calories are in 3/4 cup; 3/4 cup is 120 calories.
2. Determine how many calories are in 3 cups: 3 cups at 120 calories each equals 360 calories.
You must divide the total amount of calories in a serving of 3/4 cup by 3/4 cup to determine the unit rate for calories per cup of a certain cereal. In this instance, a serving of the cereal that is 3/4 cup in size has 120 calories. As a result, 120 calories are the number of calories in a cup. You must multiply the unit rate for calories per cup (120 calories) by 3 cups to see how many calories are in 3 cups of cereal. This indicates that there are 360 calories in 3 cups of the cereal. In summary, there are 360 calories in 3 cups of cereal, or 120 calories per cup, at the unit rate.
