Yes, this statement is correct because in quadrilaterals if two lines are parallel, then the other two sides have to be equal in length.

Triangles that are equal in all ways and interchangeable are typically described as being congruent.

A triangle with equal legs, such as an isosceles triangle, may have equal legs that are also equal to the two equal legs of another triangle with equal legs, but if the included angle is different, the triangles are not congruent.

Two sides are simply equal if their lengths are the same.

When it comes to parallelograms, both opposite side pairs are equal and parallel.

The present age of Jiya whose mother 12 year more than twice her age., is sixteen years and her mother present age is fourty-four years.

We have, Jiya's mother is 12 year more than twice of her age. Let "x years" and "y years" be the present age of Jiya and her mother respectively.

According to problem, 12 + 2x = y --(1)

After 8 years, her mother age = 20 years less then three times of her age.

After 8 years, age of Jiya = (x+8) years.

i.e y + 8 = 3( x+8) - 20 --(2)

we have to calculate the present ages of both. Simplify the equation (2),

y + 8 = 3x + 24 - 20

=> y + 8 = 3x + 4 => y = 3x -4 --(3)

eqution (1) and (3) represent the linear equations so, we solve these linear equations by substitution,

plugging the value of y from( 1) to (3),

12 + 2x = 3x -4

=> 3x - 2x = 12+4

=> x = 16 then y = 12 + 2×16 = 44

Hence, Jiya's age is 16 years and her mother is about 44 years.

The tree will be 75 feet tall when it will be fully grown.

The total tree height is the distance between the tree's base and its highest point on the ground. A yardstick provides a quick and relatively accurate way to gauge the height of a tree.

If the tree is currently 60 feet tall and is approximately 80% of its full height, we can assume that the tree will be 100% of its full height when it is fully grown. To determine the full height of the tree, we can use the proportion:

60 feet / 80% = X feet / 100%

We can then cross-multiply to solve for X:

X = (60 feet * 100%) / 80%

= 75 feet

So, when the tree is fully grown, it will be approximately 75 feet tall.

The price of the watch before the discount is calculated to be £24.44.

As the total price of the watch and a pair of trainers is £53. 55 and the price of the trainer before the discount was £38, we first calculate the price of the trainers after the discount as follows;

discount on a pair of trainers = 15/100 × 38 =  £5.7

cost of trainers after discount =  £38 - 5.7 =  £32.3

Now the price of the watch after the discount can be calculated by subtraction as follows;

price of watch after discount = total price - price of trainers after discount

price of watch after discount =  £53. 55 - £32.3

price of watch after discount = £21.25

Now the price of the watch before the discount can be calculated as follows;

price of watch before discount = £21.25 × 15/100

price of watch before discount = £21.25 + £3.1875

The solution to the system of linear equations 3y = x + 21 and y + 2/3x = 10

is (x, y) = (3, 8)

A system of linear equations is a collection of at least two linear equations.

From the question, we have the following parameters that can be used in our computation:

In this case, the system of equations is given as

3y = x + 21

y + 2/3x = 10

Next, we plot the graph of the system of equations

In this case, the point of intersection of the equations represent the solution to the system

From the graph, the lines intersect at (3, 8)

Hence, the solution is (3, 8)

In (a), we have

The lines intersect at (3, 8)

This means that

(x, y) = (3, 8)

So, we have

3 * 8 = 3 + 21 = 24

According to the standard normal distribution table, the area under the curve that is 2.25 standard deviations below the mean is approximately 1.22%.

Standard deviation is a measure of the spread or dispersion of a set of data. It tells you how much the individual values in the set differ from the mean (average) of the set.

The formula for calculating the standard deviation of a set of n data points:

Standard deviation = sqrt(((x1 - mean)^2 + (x2 - mean)^2 + ... + (xn - mean)^2) / n)

First, we need to calculate the number of standard deviations that the guarantee period of 24 months is from the mean of 33 months. We can do this by subtracting the mean from the guarantee period and dividing by the standard deviation:

(24 - 33) / 4 = -9 / 4 = -2.25

Since we are assuming that the distribution of battery lifetimes is normal, we can use the standard normal distribution table to look up the area under the curve that is 2.25 standard deviations below the mean. This area represents the proportion of batteries that will have to be replaced under the guarantee.

According to the standard normal distribution table, the area under the curve that is 2.25 standard deviations below the mean is approximately 0.0122. This means that approximately 1.22% of the batteries will have to be replaced under the guarantee.

If a hypothesis test is significant at level α = 0.05, then the P-value is less than or equal to 0.05 or P-value ≤ 0.05.

The P-value is a measure of the strength of the evidence against the null hypothesis. It is the probability of obtaining a test statistic at least as extreme as the one observed, assuming that the null hypothesis is true. If the P-value is less than or equal to the significance level α, it means that the observed evidence is unlikely to have occurred by chance under the null hypothesis, and we can reject the null hypothesis in favor of the alternative hypothesis.

For example, if the P-value of a hypothesis test is 0.03, it means that there is a 3% chance of obtaining the observed test statistic (or a more extreme one) if the null hypothesis is true. Since this is less than the significance level of 0.05, we can reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis.

Hence, if a hypothesis test is significant at level α = 0.05, then P-value ≤ 0.05.
