fndncns

20 of the 4 point and 4 of the 5 point

Step-by-step explanation:

20 x 4 = 80

4 x 5 = 20

So we get 100

Find the probability of the indicated event if ​p(e)=0.20 and ​p(f)=0.55. find​ p(e and​ f) if​ p(e or ​f)equals=0.65

The probability of the indicated event P(E and F) is 0.10 .

What is probability?

Probability is the chance of happening an event or incident.

Given, P(E) = 0.20

P(F) = 0.55

P(E or F) equals = 0.65

We know,

P(E or F) = P(E) + P(F) - P(E and F)

⇒ 0.65 = 0.20 + 0.55 - P(E and F)

⇒ P(E and F) = 0.20 + 0.55 - 0.65

⇒ P(E and F) = 0.10

#SPJ2

Using relationship
P(E or F) = P(E)+P(F)-P(E and F)
Substitute
0.65=0.20+0.55-P(E and F)
solve for
P(E and F)=0.20+0.55-0.65=0.10

Can someon plz help me solve this PLzzzzzzzzzzzzzzzzzzzz!!!!!!!!!!!!!!!!!!!!!!!!!!!! 32-6x+7x=-15+28

=>32 - 6x + 7x = -15 + 28
=>32 - 6x + 7x + 15 -28 =0
=>32 -28 + 15 -6x + 7x =0
=>19 + x =0
=>x = -19

Which number is a factor of 24 but not a multiple of 2

The number which is  is a factor of 24 not the multiple of 2 is 3

Explanation:

Find out all the factors of 24

24= 1×24

24= 2×12

24 = 3×8

24 = 4×6

24 = 6×4

24 = 8×3

24 = 12×2

24 = 24×1

So, from all the above factors, 3 is only the factor which is not the multiple of 2.

So, the factor which is  not the multiple of 2 is 3.

Step-by-step explanation:

Since 24 is divisible by 3, we say 24 is a multiple of 3.

24 is also a multiple of 1, 2, 3, 4, 6, 8, 12, and 24.

Three pizzerias claim they offer the pizza with the largest circumference. Each of the 8 slices of Mario's Pizzeria's large pizza has an area of 14.13 square inches.

Each of the 16 slices of Tito's Pizzeria's large pizza has an area of 12.56 square inches.

Each of the 10 slices of Peter's Pizzeria's large pizza has an area of 15.386 square inches.

Place the pizzas in order of least to greatest circumference. Assume all pizzas are circles and assume all pizzas have the same thickness. Use 3.14 for .

Step-by-step explanation:

Solve for the radius by plugging in what you know.

Someone else asked the same question and got something written out for them. on another site, I found out that the first one was : 8(14.13)=113.04

Explain how you know that 0.38 is a rational number?

0.38 is a rational number because it can be expressed as fraction, and it isn't a repeating decimal.

Step-by-step explanation:

Repeating decimals aren't rational, and all rational numbers can be expressed as a fraction, or they aren't rational.

It's a rational number because it stops, the decimal is irrational if it continues forever without a pattern

Explain how to write fractions that represent visual models. Use your answers from Parts 1 and 2 as a guide.

1. You make a model of any shape (I would use a square, it is easier)
2. You evenly divide it by the denominator part of the fraction
3. You fill in the sections by the numerator part of the fraction

Invasive species can enter a habitat in many ways. How were these invasive species introduced? 1.intentional introduction
2.unintentional introduction
3.loss of habitat

A. A species of rats entered a habitat stowed away in a train.

B. A man added invasive water hyacinths to beautify his private lake.

C. A flood prompted many aquatic species to inhabit a new area.

A.  A species of rats entered a habitat stowed away in a train. unintentional introduction

B.  A man added invasive water hyacinths to beautify his private lake.:.intentional introduction

C.  A flood prompted many aquatic species to inhabit a new area 3.loss of habitat

What is Intentional introduction?

Intentional introduction means an introduction made deliberately by humans, involving the purposeful movement of a species outside of its natural range and dispersal potential.

What is unintentional introduction?

Invasive species are primarily spread by human activities, often unintentionally. People, and the goods we use, travel around the world very quickly, and they often carry uninvited species with them. Ships can carry aquatic organisms in their ballast water, while smaller boats may carry them on their propellers.

What is loss of habitat?

Habitat destruction, defined as the elimination or alteration of the conditions necessary for animals and plants to survive, not only impacts individual species but the health of the global ecosystem. Habitat loss is primarily, though not always, human-caused.

A. 2. Unintentional introduction

B. 1. Intentional introduction

C. 3. Loss of habitat

Step-by-step explanation:

The rats entered the train with no interference from humans, so they were not intended to be there.

The man purposefully introduced water hyacinths to his lake to make it beautiful, so this is intentional.

The flood destroyed their habitats, so they moved to a new area. This invasion was caused by loss of habitat.
