Initially, the siblings shared 42 chocolate sweets in the ratio of 3:6:5. After their father buys 30 more chocolate sweets and gives each sibling 10 sweets, we need to determine the new ratio of the sibling share of sweets.

The initial ratio of 3:6:5 can be simplified to 1:2:5 by dividing each part by the greatest common divisor, which is 3. This means that Trust received 1 part, hardlife received 2 parts, and innocent received 5 parts.

Since their father buys 30 more chocolate sweets and gives each sibling 10 sweets, each sibling now has an additional 10 sweets. Therefore, the new distribution becomes 11:12:15.

The new ratio of the sibling share of sweets is 11:12:15.

The mean number of defects in each lot is 32, and the standard deviation is approximately 5.53.

The mean and standard deviation of the number of defects in each lot can be calculated using the binomial distribution. The mean (μ) is given by the formula μ = n × p, where n is the number of trials and p is the probability of success. In this case, the number of trials is 800 and the probability of success (defective board) is 4% or 0.04.

So, the mean of the number of defects in each lot is μ = 800 × 0.04 = 32.

The standard deviation (σ) is calculated using the formula σ = √(n × p × (1 - p)). Plugging in the values, we have σ = √(800 × 0.04 × (1 - 0.04)) ≈ √(30.72) ≈ 5.53.

The mapping diagram above is a function since every element in set A is mapped to exactly one element in set B. There is no element in set A where there are two or more arrows pointing to different elements in set B.

We are given that;

Two sets table

Now,

A mapping from set A to set B represents a function if every element in set A is mapped to exactly one element in set B. That is, there should be no repeated elements in set A and no element in set A should have more than one arrow pointing to set B.

Looking at the mapping diagram, we can see that every element in set A is mapped to exactly one element in set B. There are no repeated elements in set A and no element in set A has more than one arrow pointing to set B.

The lengths of the two segments, bar (JK) and bar (KM), are as follows:

1. Length of bar (JK): |JK| = |-4 - (-10.5)| = |-4 + 10.5| = |6.5| = 6.5 units.

2. Length of bar (KM): |KM| = |1.5 - (-4)| = |1.5 + 4| = |5.5| = 5.5 units.

The two segments, bar (JK) and bar (KM), are not congruent because their lengths are different.

To find the length of a line segment on a number line, we take the absolute value of the difference between the coordinates of the two endpoints.

For bar (JK), we subtract the coordinate of point J from the coordinate of point K. The difference is -4 - (-10.5) = -4 + 10.5 = 6.5 units.

For bar (KM), we subtract the coordinate of point K from the coordinate of point M. The difference is 1.5 - (-4) = 1.5 + 4 = 5.5 units.

Since the lengths of bar (JK) and bar (KM) are 6.5 units and 5.5 units, respectively, they are not congruent.

To approximate the solution and maximize the given objective function we need to find the steepest ascent direction and iteratively update the values of x₁ and x₂ to approach the maximum value of z.

The method of steepest ascent involves finding the direction that leads to the maximum increase in the objective function and updating the values of the decision variables accordingly. In this case, we aim to maximize the objective function z = -(x₁ - 3)² - (x₂ - 2)².

To find the steepest ascent direction, we can take the gradient of the objective function with respect to x₁ and x₂. The gradient represents the direction of the steepest increase in the objective function. In this case, the gradient is given by (∂z/∂x₁, ∂z/∂x₂) = (-2(x₁ - 3), -2(x₂ - 2)).

Starting with initial values for x₁ and x₂, we can update their values iteratively by adding a fraction of the gradient to each variable. The fraction determines the step size or learning rate and should be chosen carefully to ensure convergence to the maximum value of z.

By repeatedly updating the values of x₁ and x₂ in the direction of steepest ascent, we can approach the solution that maximizes the objective function z. The process continues until convergence is achieved or a predefined stopping criterion is met.

8 out of 1, 000 is a ratio that can be shown to be :

= 8 / 1, 000 x 100 %

= 0. 008 x 100 %

= 0. 8 %

0. 8 % is less than 1 %.

8 / 100 is a ratio that would be:

= 8 / 100 x 100 %

= 8 %

This is almost 10 % as it is 2 % away.

8 / 100 = 0. 08

2 / 25 = 0. 08

Answer:

180 degrees

Step-by-step explanation:

Transformations don't change the size or angles of a triangle.

We know the angle of T & S. We need to find R.

To do this we will do...

180 - (60+40) =

= 180-100

=80

R is 80 degrees.

Now to find Triangle ABC we will add up 60+40+80 to get 180 degrees.

Also, remember that triangles will ALWAYS add up to 180 degrees.
