We can expect to find the middle 98% of most pregnancies between 238.7 and 301.3 days and the middle 98% of most averages for the lengths of pregnancies in a sample of size 54 between 267.3 and 272.7 days.

According to the given information, the lengths of pregnancies in a small rural village follow a normal distribution with a mean (μ) of 270 days and a standard deviation (σ) of 16 days.

To find the range in which we can expect to find the middle 98% of most pregnancies, we need to find the z-scores corresponding to the lower and upper tails of 1% each, as 98% is the middle portion. Using a standard normal distribution table, we find that the z-score for the lower tail is -2.33 and the z-score for the upper tail is +2.33.

We can use these z-scores to find the corresponding values in terms of days by using the formula:

z = (x - μ) / σ

Rearranging this formula gives us:

x = μ + z * σ

Substituting the values, we get:

Lower limit = 270 + (-2.33) * 16 = 238.68 days

Upper limit = 270 + (2.33) * 16 = 301.32 days

Therefore, we can expect to find the middle 98% of most pregnancies between 238.7 and 301.3 days.

Now, if we draw samples of size 54 from this population, we can use the central limit theorem to assume that the sample means will also follow a normal distribution with mean (μ) equal to the population mean of 270 days and standard deviation (σ) equal to the population standard deviation divided by the square root of sample size (n), which is 16 / sqrt(54) = 2.17 days.

Using this information, we can again find the z-scores corresponding to the lower and upper tails of 1% each, as 98% is still the middle portion. Using a standard normal distribution table, we find that the z-score for the lower tail is -2.33 and the z-score for the upper tail is +2.33.

We can use these z-scores to find the corresponding values in terms of sample means by using the formula:

z = (x - μ) / (σ / sqrt(n))

Rearranging this formula gives us:

x = μ + z * (σ / sqrt(n))

Substituting the values, we get:

Lower limit = 270 + (-2.33) * (16 / sqrt(54)) = 267.3 days

Upper limit = 270 + (2.33) * (16 / sqrt(54)) = 272.7 days

Therefore, we can expect to find the middle 98% of most averages for the lengths of pregnancies in a sample of size 54 between 267.3 and 272.7 days.

Answer:79°

Step-by-step explanation:

Given the 124° angle, the other angle formed by that line and the top side of the square must be 56°, as they are supplementary angles (they must add up to 180°). This means that the angle formed by that same line and the bottom side of the square is also 56° since it is a corresponding angle and the top and bottom sides of a square are parallel. The angle that a diagonal of a square forms with the sides of a square is always 45°.

So now we have a triangle (in red in my diagram) with angles of 45°, 56°, and x°. The sum of the angles of a triangle must always equal 180°, so we solve for x:

56 + 45 + x = 180

x = 180 - 56 - 45 = 79

So angle x must be 79°.

Step-by-step explanation:

The idea that there is a relationship in the population and that the relationship in the sample reflects this relationship in the population is referred to as Alternative Hypothesis.

Alternative Hypothesis:

In statistical hypothesis testing, the alternative hypothesis is one of the statements proposed in the hypothesis test. In general, the purpose of a hypothesis test is to show that, given the conditions, there is sufficient evidence to support the reliability of the alternative hypothesis rather than the sole assertion in the test (the null hypothesis) . It is usually consistent with research hypotheses because it is generated from literature reviews, previous studies, etc. However, in some cases the research hypothesis is consistent with the null hypothesis.

In statistics, the alternative hypothesis is often denoted by Ha or H1. Hypotheses are formulated to compare them in statistical hypothesis testing. In the field of inferential statistics, two competing hypotheses can be compared for their explanatory and predictive power.

For scalar parameters, there are four main types of alternative hypotheses:

The smallest possible value of x is 72. To find this, we can use the formula lcm(a, b) = (a * b) / gcd(a, b), where gcd represents the greatest common divisor. We know that lcm(x, 168) = 504.

Since 168 and 504 have a common factor of 168, we can simplify the equation to lcm(x, 1) = 3. The only possible value for x that satisfies this equation is 72, as lcm(72, 168) = 504. To find the smallest possible value of x, we can use the formula for the least common multiple (lcm). Given that lcm(x, 168) is 504, we know that the product of x and 168 divided by their greatest common divisor (gcd) will equal 504. We need to find the smallest value of x that satisfies this equation. Since 168 and 504 share a common factor of 168, we can simplify the equation to x * 1 / 1 = 504 / 168. Simplifying further, we find that x = 3. Therefore, the smallest possible value of x is 72, as lcm(72, 168) indeed equals 504.

The number of 5ths in the fraction, 6/10 are 3, or there are 3 1/5s in 6/10

A fraction is a representation of a part of a whole. A fraction consists of a number (the numerator) known as the dividend, being divided by another number, (the denominator), also known as the divisor, arranged one over the other.

The expression of a fifth is 1/5

The number of fifths in 6/10 can be obtained by dividing 6/10 by 1/5 as follows;

6/10 ÷ 1/5 = 3

The number of fifths in 6/10 are 3 fifths

The number of fifths in 6/10 can also be obtained by simplifying the fraction, 6/10 as follows;

6/10 = (2 × 3)/(2 × 5) = (2/2) × (3/5)

2/2 = 1, therefore;

6/10 = 1 × 3/5 = 3/5

3/5 = 3 × 1/5

Therefore;

6/10 = 3/5 = 3 × 1/5

6/10 = 3 × 1/5

3 × 1/5 = 6/10

When three standard six-faced dice are rolled, the probability that the sum of the three numbers rolled is 9 is equal to 10/216 or 5/108.

Total number of ways three dice can be rolled = 6 × 6 × 6 = 216.

Each dice can have any number from 1 to 6. The probability of rolling a particular number on a dice = 1/6.

The probability of rolling a particular number on three dice = (1/6) × (1/6) × (1/6) = 1/216.

In order to get a sum of 9, there are four combinations that can be rolled:

3 + 3 + 3 = 9

3 + 4 + 2 = 9

3 + 5 + 1 = 9

4 + 3 + 2 = 9

The probability of rolling any of these combinations = probability of rolling 3-3-3 + probability of rolling 3-4-2 + probability of rolling 3-5-1 + probability of rolling 4-3-2

= (1/216) + (3/216) + (3/216) + (3/216)

The answer of the given question based on the area of kite is ,  the area of the kite is 60unit².

A diagonal is a straight line connecting two non-adjacent vertices of a polygon or a polyhedron. In other words, it is a line segment that connects two corners of a shape that are not next to each other.

Diagonals play an important role in geometry, as they can be used to determine various properties of shapes. For instance, the length of the diagonal of a rectangle can be used to find its area and perimeter, and the length of the diagonal of a cube can be used to find its volume and surface area.

To find the area of a kite, we need to know the lengths of its two diagonals. Let d1 and d2 be  length of  two diagonals of  kite.

In this case, we know that the two diagonals have lengths 15 and 8. Let's label them as d1 = 15 and d2 = 8.

The area of kite can be calculated using formula:

Area = (1/2) x d1 x d2

Substituting  values of d1 and d2, we will get:

Area = (1/2) x 15 x 8

Area = 60

Therefore, the area of the kite is 60unit².
