The reason why the events "choosing an odd number" and "choosing an even number" are mutually exclusive is; Choice D; a number is either even or odd.

It follows from probability theory, that two events are characterized as mutually exclusive if they cannot both occur at the same time. A very good example is the set of outcomes of a single die roll, which can result in any of the 6 outcomes.

From the question, we understand that the sample size cannot be changed

This means that the standard deviation, and the mean cannot be altered too.

Since the value of the significance level is not constant, David can decide to adjust the significance level.

Answer:

7.3 cm

Explanation:

Given a right angle triangle, In order to find the third side: Use Pythagoras Theorem: a² + b² = c²

Insert values:

x² + 8.9² = 11.5²

x² + 79.21 = 132.25

x² = 132.25 - 79.21    (subtract)

x² = 53.04

x = √53.04                (square root)

x = 7.28285 ≈ 7.3     (rounded to 1 decimal place)

11.5 cm

8.9 cm

the unknown value "x"

we'll have to use pythagoras theorem.

unknown value is x

[tex] {c}^{2} = {b}^{2} - {a}^{2} [/tex]

The length of the straw will be 5.91607 inches long in radical form.

If a cuboid has length = l units, breadth = b units, and height = h units, then we can evaluate the length of the diagonal of a cuboid using the formula

[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]

As per the question the length of the straw is equal to length of the diagonal of Rectangular box.

l= 3 inch , b= 5 inch , h= 1 inch

Let us consider the length of the straw be 'x'.

As, Diagonal of Cuboid is,

[tex]X^{2}= l^{2}+b^{2}+h^{2}[/tex]

[tex]X^{2}= 3^{2}+5^{2}+1^{2}\\X^{2}= 9+25+1\\X^{2}= 35\\X= \sqrt{35}[/tex]

X= 5.91607 (in radical form)

Hence, the length of the straw will be  5.91607 inches.

Let

potato be 9x,cheese be 2x and onion be x

Cheese

Total 175gs

Total cost

Answer:

£12.86 (nearest pence)

Step-by-step explanation:

Given ratio:

Sum the ratios:  

⇒ 9 + 2 + 1 = 12

Divide the total weight by the sum of the ratios:

⇒ 6000 g ÷ 12 = 500

Multiply each ratio by 500 to find the amount of each ingredient needed to make 6000 g of potato cakes:

⇒ potato = 9 × 500 = 4500 g

⇒ cheese = 2 × 500 = 1000 g

⇒ onion = 1 × 500 = 500 g

If 175 g of cheese costs £2.25, then 1000 g of cheese costs:

⇒ (2.25 / 175) × 1000 = £12.86 (nearest pence)

The possible quantum numbers for the value of n=4 will be i=0,1,2,3.

The number of elements in a quantum is the count of 0 to n - 1 where n is the principal quantum number. There are 4 different values of i in quantum number n =4.

Given that:

[tex]n=4[/tex] -- quantum number

To count the quantum numbers (i), we make use of the following set:

[tex]i=[0,1,2,3............n-1][/tex]

The value of n is: [tex]n=4[/tex]

So, the set will be populated as follows

[tex]i=(0,1,2,3)[/tex]

The number of elements in the set is 4.

This means that there are 4 different values of i

Answer:  (2,3) and (2,5) cause the relation to not be a function

Explanation:

The input x = 2 leads to y = 3 and y = 5 at the same time for both points. A function is where any input x leads to exactly one y output only. So we'd need to get rid of one of those mentioned points to be able to have a function.

If you graphed the points on the same xy grid, then you'd see (2,3) and (2,5) vertically aligned. These two points cause the vertical line test to fail. This will give a visual indication we do not have a function.

Put another way, if x repeats itself then we don't have a function. The y value is allowed to repeat. So we could have something like (1,2) and (5,2) be part of a function.

The horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

Given that:-

The horizontal distance will be calculated by applying the angle property in the right angle triangle.

tan45  =  (  P  /  B  )

B  =  P  /  tan45

B  =  P                                 Since ( tan45 =1 )

B  =  1140 feet.

Therefore the horizontal distance from the base of the skyscraper out to the ship will be 1140 feet.
