The output value of f( 38 ) in the function f( x ) = x/2 is 19.

A function is simply a relationship that maps one input to one output, that is, each x-value can only have one y-value.

Given the data in the question;

To determine the output value of f( 38 ), replace all the occurrence of x with 38 in the function and simplify.

f( x ) = x/2

f( 38 ) = 38/2

Divide 38 by 2

f( 38 ) = 38/2

f( 38 ) = 19

Therefore, the output value is 19, this forms an ordered pair of ( 38,19 ).

A. P( 2∪3∪6 ) = 1/2

B. P( 1∪2∪3∪4∪5 ) = 9/16

The probability of an occurrence e can be written as P (e), and its equation is as follows:

P (e) = Number of favorable outcomes / Total number of outcomes

This can only be used with a straightforward event.

The probability will also be influenced by other factors, whether they are imposed or a result of the event's inherent characteristics.

Using a six-sided die,

A) First, in order to gather as much information as possible from the question, we concentrate on the probabilities provided P(1∪4∪5)=1/2 and P(2∪3∪5)=1/2 and we need to use P(5)=7/16.

It's crucial to remember that while using a dice, receiving two values on the same roll is impossible. Due to this and the likelihood of certain circumstances:

P(1∪4∪5) = P(1) + P(4) + P(5) - P(1∩4)(= 0) - P(4∩5)(= 0) - P(1∩5)(= 0) + P(1∩4∩5)(= 0)

P(1∪4∪5)=P(1) + P(4) + P(5)

1/2 = P(1) + P(4) + 7/16

P(1)+P(4)=1/16

If we do the same with P(2∪3∪5), we get:

P(2) + P(3) = 1/16

Now that we have this new knowledge, we can determine P(6):

P(6) = 1 - P(1∪2∪3∪4∪5)

P(6) = 1 - [P(1) + P(2) + P(3) + P(4) + P(5)] -- (There is no chance that two of these will occur simultaneously.)

P(6) = 1 - (1/16 + 1/16 + 7/16)

P(6) = 1 - 9/16

P(6) = 7/16

And with it, we can find P(2∪3∪6):

P(2∪3∪6) = P(2) + P(3) + P(6)

P(2∪3∪6) = 1/16 + 7/16

P(2∪3∪6) = 8/16 = 1/2

B) Keep in mind that the probability you need to know if you wish to roll anything other than a 6 is P(1∪2∪3∪4∪5)" but we found that in part A

P(1∪2∪3∪4∪5) = 9/16

The associative property can be applied to addition and multiplication.

When more than two numbers are added together or multiplied, the outcome is always the same, regardless of how the numbers are arranged. This is known as the associative property.

For example,

2 × (7 × 6) = (2 × 7) × 6

2 + (7 + 6) = (2 + 7) + 6

Associative Addition Property

The associative feature of addition states that the total sum of the numbers will not change no matter how they are arranged. This may be stated as follows:

(x + y) + (z + y) = x

Associative Multiplication Property

Using the given information, the fraction is 3/8

From the question, we are to determine the fraction

Let the numerator of the fraction be x and the denominator be y

From the given information,

"if the numerator of a fraction is multiplied by 4 and the denominator is reduced by 2, the result is 2"

That is,

4x/(y -2) = 2

and

" If the numerator of the fraction is increased by 15 and 2 is subtracted from the double of the denominator, the result is 9/7"

That is,

(x + 15)/(2y - 2) = 9/7

From the first equation,

4x/(y -2) = 2

4x = 2(y-2)

4x = 2y - 4

4x + 4 = 2y

y = 2x + 2 ----------- (3)

From the second equation,

(x + 15)/(2y - 2) = 9/7

7(x + 15) = 9(2y - 2)

7x + 105 = 18y - 18

Substitute equation (3)

7x + 105 = 18(2x + 2) - 18

7x + 105 = 36x + 36 - 18

105 - 36 + 18 = 36x - 7x

87 = 29x

x = 87/29

x = 3

Substitute the value of x into equation (3)

y = 2x + 2

y = 2(3) + 2

y = 6 + 2

y = 8

therefore, when 64 is increased in the ratio 9:8 we get:

Answer: 72.

Answer:

Since X : 64 = 9 : 8

Then we know X/64 = 9/8

Multiplying both sides by 64 cancels on the left64 × (X/64) = (9/8) × 64

X = (9/8) × 64Then solving for X X = 64 × (9/8)X = 72

The possible change in volume (in mm3) resulting from the error in measuring the radius is 32. 06 mm³

The formula for volume of a sphere is expressed by;

Volume = 4/3 πr³

Where;

From the information given, we have that the measured radius is 5 mm, with a possible measurement error of 0.1 mm

Then, radius  a = 5mm

Radius b = 5 + 0. 1 = 5. 01mm

Now, substitute the values into the formula

Volume, v = 4/ 3 (3.14)(5)³

expand the bracket

Volume, v = 4/ 3 (392.5)

Volume, v = 523. 3 mm³

For radius of 5.01mm

Volume =  4/ 3 (3.14)(5.1)³

expand the bracket

Volume = 4/3 (416.52)

Volume = 555. 4 mm³

The change in volume = 555. 4 - 523. 3 = 32. 06 mm³
