Answer:

x = 55°

Step-by-step explanation:

Hello!

The sum of angles in a triangle is 180°.

To solve for x, we have to subtract the given angles from 180°.

The value of x is 55°.

Angle sum property of a triangle

∠A + ∠B + ∠C = 180°

We need to find the value of ∠A

According to the angle sum property of a triangle

⇢∠A + ∠B + ∠C = 180°

⇢∠A + 75° + 50° = 180°

⇢∠A + 125° = 180°

⇢∠A = 180° - 125°

⇢∠A = 55°

The confidence interval is  0.028, 0.872

862 of 1013 randomly selected adults  wear seat belts.

The 95% confidence interval for the proportion of adults who always wear seat belts.

A Confidence Interval is defined as a range of values we are sure our true value lies within it.

A 95% confidence interval is defined as that if we take 100 different samples and compute a 95% confidence interval for each sample, then approximately 95 of the 100 confidence intervals will contain the true mean value.

= 862/1013 = 0.85

At a 95% confidence interval ,the critical value is \(z_{0.025} = 1.96\)

The 95% confidence interval for proportion is

\(\widehat p +/- z0.025 * sqrt(\widehat p * (1 - \widehat p)/n)\)

\(= 0.85 +/- 1.96 * sqrt(0.85 * (1 - 0.85)/1013)\)

\(= 0.85 +/- 0.022\)

= 0.028, 0.872

The sample should use at least 10 successes and 10 failures.

\(n * \widehat p = 1013 * 0.85 = 861 > 10\)

\(n * (1 - \widehat p) = 1013 * 0.15 = 152 > 10\)

As the sample size is larger, we can use an approximate formula for the standard error.

The 96 % confidence interval for the cans, given the diameter and standard deviation, is (50.45, 53.55).

The 96% confidence interval for the mean diameter of soda cans manufactured by the company can be calculated using the following formula:

= Mean ± (critical value x standard deviation / square root of sample size)

The critical value for a 96 % confidence interval is 2. 33 so the lower bound of the interval is:

= 52 - ( 2.33 x 2. 3 / √12 )

= 50. 45

The upper bound of the interval is:

Step-by-step explanation:

To find the Highest Common Factor (H.C.F.) of 567 and 255 using Euclid's division lemma, we can follow these steps:

Step 1: Apply Euclid's division lemma:

Divide the larger number, 567, by the smaller number, 255, and find the remainder.

567 ÷ 255 = 2 remainder 57

Step 2: Apply Euclid's division lemma again:

Now, divide the previous divisor, 255, by the remainder, 57, and find the new remainder.

255 ÷ 57 = 4 remainder 27

Step 3: Repeat the process:

Next, divide the previous divisor, 57, by the remainder, 27, and find the new remainder.

57 ÷ 27 = 2 remainder 3

Step 4: Continue until we obtain a remainder of 0:

Now, divide the previous divisor, 27, by the remainder, 3, and find the new remainder.

27 ÷ 3 = 9 remainder 0

Since we have obtained a remainder of 0, the process ends here.

Step 5: The H.C.F. is the last non-zero remainder:

The H.C.F. of 567 and 255 is the last non-zero remainder obtained in the previous step, which is 3.

Therefore, the H.C.F. of 567 and 255 is 3.

The VAT amount that should be paid by the contractor is Rs. 19,000.

To calculate the VAT amount that should be paid by the contractor, we need to follow the given information and calculate the necessary values step by step.

Laligurash suppliers sold construction materials worth Rs. 2,00,000 to Himchuli suppliers, making a 20% profit and adding 13% VAT.

Profit made by Laligurash suppliers = 20% of Rs. 2,00,000 = Rs. 40,000

Total amount paid by Himchuli suppliers to Laligurash suppliers = Rs. 2,00,000 + Rs. 40,000 = Rs. 2,40,000

VAT amount on the purchase for Himchuli suppliers = 13% of Rs. 2,40,000 = Rs. 31,200

Himchuli suppliers spent Rs. 6,000 for transportation cost and made a 10% profit on the purchased price (excluding VAT).

Profit made by Himchuli suppliers (excluding VAT) = 10% of Rs. 2,40,000 = Rs. 24,000

Total cost incurred by Himchuli suppliers = Rs. 2,40,000 + Rs. 6,000 = Rs. 2,46,000

Total selling price by Himchuli suppliers to the constructor = Rs. 2,46,000 + Rs. 24,000 = Rs. 2,70,000

Himchuli suppliers levied a local tax of Rs. 5,000.

To calculate the VAT amount that should be paid by the contractor, we subtract all the costs and taxes from the selling price:

VAT amount for the contractor = Selling price - (Total cost + Local tax)

= Rs. 2,70,000 - (Rs. 2,46,000 + Rs. 5,000)

= Rs. 19,000

Therefore, the VAT amount that should be paid by the contractor is Rs. 19,000.

The disposable income is 4,000, consumption is 3,500, government purchases is 1,000, and taxes minus transfers are 800, national saving is equal to. Therefore, S = 4,000 - 3,500 - 1,000 = 500.Hence, option b is correct.

National savings (S) can be calculated as: S = Y - C - G, where Y is income, C is consumption, and G is government purchases.

To determine S, we must first calculate Y.Y = C + I + G + NX, where I is investment, and NX is net exports.

The formula for calculating national savings is as follows: National savings (S) = Y - C - G

The following is a numerical representation of the above data:Y = C + I + G + NX = 3,500 + I + 1,000 + NX

Disposable income is 4,000, while taxes minus transfers are 800. Therefore, Y + TR - T = C + S.

Now, let's compute this value.

Substitute the given values in the equation4,000 + TR - 800 - T = 3,500 + S600 - T = S + 3500 - 1000S = 500

The result is consistent with the previous calculation, and option C, 3.682, is the correct answer.

To calculate log4 57 to the nearest thousandth, we can use a scientific calculator or a logarithmic table.

Using a calculator, we can find the logarithm of 57 to the base 4 directly:

log4 57 ≈ 3.682

Therefore, the correct answer is option C: 3.682.

If you prefer to verify the result using logarithmic properties, you can do so as follows:

Let's assume log4 57 = x. This means \(4^x\) = 57.

Taking the logarithm of both sides with base 10:

log (\(4^x\)) = log 57

Using the logarithmic property log (\(a^b\)) = b \(\times\) log a:

x \(\times\) log 4 = log 57

Dividing both sides by log 4:

x = log 57 / log 4

Using a calculator to evaluate the logarithms:

x ≈ 3.682

Thus, the result is consistent with the previous calculation, and option C, 3.682, is the correct answer.

The correct answer is: z-test statistic = 3.41, p-value = 0.0003. To find the standardized test statistic (z-test statistic) and corresponding p-value, we will use the following formula: z = (sample mean - hypothesized mean) / (standard deviation / sqrt(sample size))


To find the standardized test statistic, we use the formula:

z = (sample mean - hypothesized mean) / (standard deviation / sqrt(sample size))

Plugging in the values given, we get:

z = (78 - 75) / (5.9 / sqrt(45))
z = 3.41

To find the corresponding p-value, we can use a standard normal distribution table or calculator. The p-value represents the probability of getting a z-score as extreme or more extreme than the one we calculated. Since our z-score is positive, we are interested in the area to the right of it on the standard normal distribution. This gives us a p-value of 0.0003.

Therefore, the correct answer is: z-test statistic = 3.41, p-value = 0.0003.
To find the standardized test statistic (z-test statistic) and corresponding p-value, we will use the following formula:

z = (sample mean - hypothesized mean) / (standard deviation / sqrt(sample size))

z = 3 / (5.9 / 6.708)

z = 3 / 0.880

z ≈ 3.41

Using a standard normal distribution table or a calculator, we find the area to the right of the z-score (since we're testing if the braking distance is greater than the hypothesized mean):
