Suppose S and T are mutually exclusive events, P(S) = 30%, and P(T) = 24%. Find P(S or T).
A) 6%
B) 54%
C) 720%
D) 7.2%

Answers

Answer: 54%

Step-by-step explanation:

In probability and logic theory, two events are said to be mutually exclusive or disjoint when both events cannot occur or happen at the same time.

A clear example of mutually exclusive event is the set of outcomes of a single toss of a coin which can either result in heads or tails, but can not be both.

P(S) = 30%, and P(T) = 24%

P(S or T) = P(S) or P(T) = 30% + 24%

= 54%

Circle 2 = 706.5 in²

Circle 3 = 271.6 in²

Step-by-step explanation:

In order to find the Diameter of a circle, you have to multiply the radius by 2. According to circle 1, 12in (radius) multiplied by 2 gets you 24 pi in².

In order to find the area, you multiply the radius² and then multiply it by pi or 3.14.

Answers

Answer:

158 degrees

Step-by-step explanation:

Step 1:

Let Angle CDE =y

Since Angle BCD = 2 X angle CDE

Angle BCD = 2y

Step 2

Consider Figure 2 attached, each of the figure forms an isosceles trapezoid ABCF and DEFC.

By these properties of Isosceles Trapezoids

Lower Base Angles are CongruentUpper base angles are congruentAny lower base angle is supplementary to any upper base angle

Therefore:

[tex]\angle ABC+\angle BCF=180^\circ\\\angle FCD+\angle CDE=180^\circ\\Therefore:\\\angle ABC+\angle BCF+\angle FCD+\angle CDE=360^\circ\\$But \angle BCF+\angle FCD=\angle BCD\\So:\\\angle ABC+\angle BCD+\angle CDE=360^\circ[/tex]

123+2y+y=360

3y=360-123

3y=237

y=79 degrees

Therefore:

[tex]\angle BCD=2 X 79^\circ=158^\circ\\\angle BCD=\angle AFE=158^\circ\\\angle AFE=158^\circ[/tex]

Answers

Answer:

Step-by-step explanation: dk

Scale factors are used to enlarge or reduce the size of a shape

The area of polygon w is 49 square units

The area of polygon v is given as:

[tex]v =1[/tex]

The scale factor of the sides of polygon v, that forms polygon w is given as:

[tex]k=7[/tex]

The area of polygon w is then calculated as:

[tex]w =v\times k^2[/tex]

So, we have:

[tex]w =1\times 7^2[/tex]

Evaluate the exponents

[tex]w =1\times 49[/tex]

Multiply 1 and 49

Plzzzzzzz help In the number 3.9928, how does the value of the 9 in the tenths place compare to the value of the 9 in the hundredths place? Drag and drop a fraction into the box to correctly complete the statement. The value of the 9 in the tenths place is the value of the 9 in the hundredths place.

Answers

Answer:

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

or

The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place

Step-by-step explanation:

The decimal we are considering is 3.9928

The 9 in the tenth place has a value of 0.9

The value of 9 in the hundredth place has a value of 0.09

Now, what fraction of the 9 in the tenth place is the 9 in the hundredth place.

To mathematically get this, we just need to place the value of 9 in the hundredth place over the value of 9 in the tenth place;

Mathematically, that would be;

0.09/0.9 = 0.1 = 1/10

This means that the value of 9 in the hundredth place is 1/10 the value of 9 in the tenth place

or

The value of 9 in the tenth place is 10 times the value of 9 in the hundredth place

This diagram shows a block of stainless steel. The mass of the block is 930g.

Calculate the density of stainless steel.

Giving away brainliest! PLEASE HELP :)

Answers

Answer:

the answer is  7.75 g/cm3

Step-by-step explanation:

hope this helps

The density of the given block of stainless steel is 7.75 g/cubic cm. The value is obtained by the ratio of its mass to its volume.

What is the density of the cuboid?

The cuboid has rectangular faces with length(l), width(w), and height(h). So, the density of the material which is required to make the cuboid is calculated as follows:

Density = mass/volume

Where the volume of the cuboid is the product of length, width, and height.

I.e., Density = mass/ (l × w × h)

Calculation:

The given block has

length(l) = 8cm

width(w) = 5cm

height(h) = 3cm

The mass of the block is given as 930g

So, the density of the stainless steel is

Density = 930g/(8 × 5 × 3) cm³

            = 930/120 (g/cm³)

            = 7.75 g/cm³

Therefore, the density of the block is 7.75 g/cubic cm.
