Answer:

x = 70

Step-by-step explanation:

The total sum of all of the angles in a parallelogram is equal to 360 degrees. Opposite angles are also congreuent meaning that angle ADC and angle ABC are equal. Adding the sum of the two angles gives you 220. Subtract 220 form 360 and you get 140 which is equal to the sum of angles BCD and BAD. Angles BCD and BAD and the sam so dividing 140 by 2 would give you the angle measure of x.

From the above, we have

Pass total = 50 - 10

Pass total = 40

Next, we have

Pass studied = 40 - 6

Pass studied = 34

So, the table becomes

Next, we have

Total Did not study = 50 - 38

Total Did not study = 12

Also, we have

Failed study = 38 - 36

Failed study = 2

Falied Did not study = 12 - 6

Falied Did not study = 6

0.590 grams of magnesium metal will be deposited from a solution that contains Mg2+ ions if a current of 1.18 A is applied for 28.5 minutes and 512.02 seconds are required to deposit 0.215 grams of cobalt metal from a solution that contains Co2+ lons if a current of 0.686 A is applied.

1) Calculation of grams of magnesium metal deposited

Number of moles of electrons transferred = (current in Amperes × time in seconds) / (Faraday’s constant)Faraday’s constant = 96500 C mol-1

Therefore, number of moles of electrons transferred = (1.18 × 28.5 × 60) / 96500 = 0.0243 moles

Mg2+ + 2e- → Mg Molar mass of Mg = 24.31 g mol-1

Hence, mass of magnesium = Number of moles × Molar mass= 0.0243 × 24.31= 0.590 gram

Therefore, 0.590 grams of magnesium metal will be deposited from a solution that contains Mg2+ ions if a current of 1.18 A is applied for 28.5 minutes.

2) Calculation of seconds required to deposit 0.215 grams of cobalt metal from a solution that contains Co2+ ions

Faraday’s constant = 96500 C mol-1

Number of moles of electrons transferred = (current in Amperes × time in seconds) / (Faraday’s constant)Molar mass of Co = 58.93 g mol-1Co2+ + 2e- → Co

Hence, moles of electrons transferred = (0.686 A × t sec) / (96500 C mol-1) = 0.215 / 58.93= 0.00364 moles

Therefore, the time required to deposit 0.215 grams of cobalt metal from a solution that contains Co2+ lons

if a current of 0.686 A is applied is;0.686 A × t sec = (96500 C mol-1 × 0.00364 mol) = 351.04

Therefore, t = 351.04 / 0.686= 512.02 seconds

Thus, 512.02 seconds are required to deposit 0.215 grams of cobalt metal from a solution that contains Co2+ lons

if a current of 0.686 A is applied.

Answer:

Pretend that the question did not have $5 more and just asked how much Ted had.

25 - 5 = 20

20 ÷ 2 = 10 (How much they both have without the "Vera has $5 more than Ted)

If the question asked for Vera, it would be $15 as it's 10 + 5.

The correct answer is: B. No, there is no linear association since r is positive and is less than the critical value.

In the given answer choices, it states that r (the correlation coefficient) is positive. A positive correlation indicates a tendency for the variables to move in the same direction. However, the question asks whether a linear relation exists between the commute time and well-being index score, not the direction of the association.

Furthermore, the answer suggests that the correlation coefficient is less than the critical value. The critical value is a threshold used to determine the statistical significance of the correlation. If the correlation coefficient is less than the critical value, it indicates that the correlation is not statistically significant.

Therefore, based on the information given, we cannot conclude that there is a linear relation between the commute time and well-being index score.

All of the following are measures of central tendency except the range.

The range is a measure of dispersion, representing the difference between the largest and smallest values in a dataset. It provides information about the spread or variability of the data but does not provide information about the central tendency.

On the other hand, measures of central tendency are statistical measures that aim to summarize the center or typical value of a dataset. They include the mode, median, and mean.

The mode represents the most frequently occurring value(s) in the dataset.

The median is the middle value when the data is arranged in ascending or descending order. It divides the dataset into two equal halves.

The mean is the arithmetic average of all the values in the dataset. It is calculated by summing all the values and dividing by the total number of values.

Therefore, option C, range, is not a measure of central tendency as it focuses on the spread or dispersion of the data rather than summarizing the central or typical value.

What is a proportional relationship?

Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. where the constant of proportionality is also known as slope.

Given, a proportional relationship that can be represented by the equation   y=25x

In the above equation, the constant of proportional = 25

If Sandra has a bunch of grapes that weighs 48.64 g and a bag of mangoes that weighs 937.2 g. The amount that the fruit weight in total is: $985.84.

Using this formula to determine the fruit weight in total

Total fruit weight = Weight of bunch of grapes + Weight of bag of mangoes

Where:

Weight of bunch of grapes = 48.64g

Weight of bag of mangoes = 937.2g

Let plug in the formula

Total fruit weight = 48.64g +  937.2g

Total fruit weight = 985.84g

The percentage error in the deer population is 17%

Actual population = 21300

Estimated population = 17600

The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:

= (Actual population - Estimated population) / Actual population × 100

= (21300 - 17600) / 21300 × 100

= 3700/21300 × 100

Let's call our first integer x and our second integer, x + 1.

Sine there sum is 41, that means that x + (x + 1) = 41.

Simplifying on the left, we have 2x + 1 = 41.

Now subtract 1 from both sides to get 2x = 40.

Now divide both sides by 2 and x = 20.

So our first integer is 20 and our second

integer is x + 1  or 20 + 1 which is 21.

The integers are 20 and 21.

Answer:

20 and 21

Step-by-step explanation:

X is the first integer, and let Y be the second.
X + Y must be 41, but Y must also be X + 1.
2x has to equal 40 if that's the case

Therefore X must be 20.
And Y must be 20 + 1 which is 21.
20 + 21 = 41.

To determine which region represents the solution to a system of linear inequalities, you need to graph each inequality on the same coordinate plane and then find the intersection of the regions that satisfy each inequality. This intersection is the solution to the system of linear inequalities, as every point in this region satisfies all of the inequalities in the system.

To graph the solution, you can use a number line for each variable and plot the inequalities as points or lines on the coordinate plane. For example, if the system of linear inequalities is given by the equations y > 2x + 3 and y < -x + 5, you can plot the lines y = 2x + 3 and y = -x + 5 on the coordinate plane and find the intersection of the two lines. This intersection represents the solution to the system of linear inequalities, as every point in this region satisfies both inequalities.

Another way to find the solution to a system of linear inequalities is by using algebra to solve the system. This involves writing the equations in standard form, eliminating variables, and solving for the remaining variable. The solution can then be written as a set of ordered pairs that represent the points on the coordinate plane that satisfy the system of linear inequalities.

In either case, the solution to a system of linear inequalities is the region of the coordinate plane that satisfies all of the inequalities in the system.

The exponential growth rate is obtained as 0.1099.

Now we know that an exponential function has to do with an exponential increase or decrease. An exponential function could increase or decrease and this means that the constant of the function could be a decay constant or a growth constant.

When we have an exponential function, we have to apply the general formula; P(t) = P(o)e^rt

Po = initial number

P(t) = number at time t

r = rate of growth

t = time taken

Thus;

270=90e^10r

270/90 = e^10r

3 = e^10r

ln3 = 10r

r = ln3/10

r = 0.1099
