The size of angle DAB in the quadrilateral is 48°.

The sum of the interior angles of a quadrilateral is 360°. We can say:

\(\angle \text{A} +\angle\text{B} + \angle\text{C} + \angle\text{D} = 360^\circ\)

\(\angle \text{A} +38^\circ + \angle\text{C} + 226^\circ = 360^\circ\)

\(\angle \text{A} + \angle\text{C} + 264^\circ = 360^\circ\)

\(\angle \text{A} + \angle\text{C} = 360^\circ- 264^\circ\)

\(\angle \text{A} + \angle\text{C} = 96\)

Since angles DAB and BCD are the same size. This implies ∠A  = ∠C. Thus:

\(\angle\text{A} + \angle\text{A} = 96\)

\(2\angle\text{A} = 96\)

\(\angle\text{A} = \dfrac{96}{2}\)

\(\angle\text{A} = 48^\circ\)

Therefore, the size of angle DAB is 48°.

The amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The meaning of unit price is a price quoted in terms of so much per agreed or standard unit of product or service

Given that, a woman bought 1.8 kg of chicken and 1.6 kg of meat. The chicken cost $5.40 and the meat cost $6.40,

We need to find, if she had bought 2.4 kg of chicken and 2 kg of meat, how much would she have had to pay,

To find the same, we will first find the unit price of each,

Unit price = total price / total quantity

Since, 1.8 kg of chicken costs $5.40,

Therefore, 1 kg will cost = 5.40 / 1.8 = $3

Similarly,

If 1.6 kg of meat costs $6.40,

Therefore, 1 kg will cost = 6.40 / 1.6 = $4

Now, to find the cost of 2.4 kg of chicken and 2 kg of meat, we will multiply the unit prices to the required quantities,

Therefore,

2.4 kg of chicken will cost = 2.4 x 3 = $7.2

2 kg of meat will cost = 2 x 4 = $8

In total, she had to pay = 8+7.2 = $15.2

Hence, the amount the women would pay for 2.4 kg of chicken and 2 kg of meat in total is $15.2

The value of the angle x is 30 degrees

To determine the value of the variable x, we need to know the triangle sum theorem.

The triangle sum theorem is a theorem in mathematics stating that the sum total of the interior angles in a triangle is equivalent to 180 degrees.

We should also note that angle at right angle is 90 degrees

Then, we have the angles written as;

90 degrees

2x degrees

x degrees

Equate the angles , we have;

2x + x + 90 = 180

collect the like terms, we have;

2x + x = 180 - 90

The mean of a distribution is 217, while the median is 217.The statements is likely to be true about the distribution is  option  D. It is not symmetrical.

The distribution is likely to be asymmetrical if the mean and median have different values. If the mean and median of a distribution are equal, it is likely that the distribution is symmetrical, which means it has equal tail sizes on both sides. However, if the mean and median are not equal, it indicates that the distribution is skewed.

A negatively skewed distribution means that the mean is less than the median, whereas a positively skewed distribution means that the mean is greater than the median.In this case, since the mean and median of the distribution are equal, it is likely to be symmetrical.

–0.4x – 10 > 14

           –0.4x > 24

                    x < –60

the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.

Inequality refers to a mathematical relationship between two values that are not equal.

The correct work that uses properties of inequality to find the solution to – 0.4 x – 10 > 14 is:

– 0.4 x – 10 > 14

Subtract 10 from both sides:

– 0.4 x > 24

Divide both sides by – 0.4 (note the change in inequality direction when dividing by a negative number):

x < – 60

The probability that the customer actually has a credit score above 700, given that the credit bureau reports a score above 700, is approximately 0.995. Bayes' theorem and the law of total probability were used to calculate the probability.

7. The probability that the customer actually has a credit score above 700, given that the credit bureau reports a score above 700, can be calculated using Bayes' theorem:

P(score > 700 | bureau reports score > 700) = P(bureau reports score > 700 | score > 700) * P(score > 700) / P(bureau reports score > 700)

We know that P(score > 700) = 0.20 and P(bureau reports score > 700 | score > 700) = 0.95. To find P(bureau reports score > 700), we can use the law of total probability:

P(bureau reports score > 700) = P(bureau reports score > 700 | score > 700) * P(score > 700) + P(bureau reports score > 700 | score <= 700) * P(score <= 700)

P(bureau reports score > 700) = 0.95 * 0.20 + 0.05 * 0.80

P(bureau reports score > 700) = 0.19

Now we can plug in the values:

P(score > 700 | bureau reports score > 700) = 0.95 * 0.20 / 0.19 ≈ 0.995

Therefore, the probability that the customer actually has a credit score above 700, given that the credit bureau reports a score above 700, is approximately 0.995.

8. P(score > 700 | bureau reports score > 700) = P(bureau reports score > 700 | score > 700) * P(score > 700) / P(bureau reports score > 700)

= 0.95 * 0.20 / (0.95 * 0.20 + 0.05 * 0.80)

= 0.995 (rounded to three decimal places)

We used Bayes' theorem to calculate the probability, and the law of total probability to find P(bureau reports score > 700).

We Know

How many ft makes a height of 1.66m?

We Take

So, the answer is 5.44 meters.

Answer:

Since the calculated value of z= 1.869 does not fall in the critical region we accept the null hypothesis H0: p1≠ p2  the data provides evidence that the proportion of high school students in metropolitan areas who have internet access during school hours is different than the proportion of rural high school students who have internet access during school hours.

Step-by-step explanation:

Let p1= proportion of the high school students having internet access

p2= proportion of the rural school students having internet access

1) The null and alternate hypothesis are

H0: p1≠ p2  against the claim   Ha: p1= p2

2) We choose significance level ∝ =0.05

3) The test statistic under H0 is

z= p1^- p2^/√ p^q^( 1/n1 + 1/n2)

Now

p1^= 768/850= 0.9035

p2^= 308/355= 0.8670

p^= 768+ 308/850+ 355= 1076/1205

p^= 0.8929

q^= 1-p^= 0.1070

Putting the values

z= p1^- p2^/ √p^q^( 1/n1 + 1/n2)

Z= 0.9035-0.8670/sqrt [0.8929*0.1070( 1/850 + 1/355)]

z= 0.0365/ sqrt [ 0.0955403 (0.001176 + 0.002816)]

z= 0.0365/ 0.019531

z= 1.8688

The critical region is  z∝/2 = ± 1.96

The value of z is 1.8666. The value of p is 0.06148 which is greater than 0.05

Conclusion:

Since the calculated value of z= 1.869 does not fall in the critical region we accept the null hypothesis H0: p1≠ p2  the data provides evidence that the proportion of high school students in metropolitan areas who have internet access during school hours is different than the proportion of rural high school students who have internet access during school hours.
