So 4x^2+-2x+-6 then multiply by 5 would be the Area of the entire rectangle using the formula A=bh

You'll get 4x^2 − 2x − 6

a = 5

b = 4x² - 2x - 6

The area is:

a · b = 5(4x² - 2x - 6) = 20x² - 10x - 30

Or you can add areas of shapes:

- blue: 5 · 4x² = 20x²

- pink: 5 · (-2x) = -10x

- green: 5 · (-6) = -30 <- a little strange, the length of a side shouldn't be negative

Sum of those areas is the area of entire rectangle: 20x² - 10x - 30

But the first option is easier here.

Seven different names were put into a hat. A name chosen 100 times. And the name Michael is chosen 9 times. What is experimental

iris [78.8K]

Answer:

Experimental probability = 9 / 100

Theoretical probability = 1/7

Step-by-step explanation:

The experimental probability of an event is written as :

P = number of times event occur / total number of trials

Experimental probability is based on the outcome of an experiment that has taken place.

Theoretical probability is based on expected outcome of an event.

P = number of expected or required outcomes / total possible outcomes

Experimental probability of choosing the name Michael is :

Number of times Michael is chosen / number of trials

Experimental probability = 9 / 100 = 0.09

Theoretical probability of choosing michael:

Number of names in hat = 7

Number of names called Michael in hat = required outcome = 1

P = 1 / 7

If the number of names in hat was different from 7, then the theoretical probability will change.

Also, if the number of times a name was chosen was different from 100, then number of trials will also change and hence, the experimental probability.

Hi,

$f(x)=\log(x)$ FALSE

$f(x)=\log(x-4)+1$ TRUE

→ $f(x)=\log(x-2)$

$f(x)=\log(x+2)$ FALSE

$f(x)=2log(x)$ TRUE

25 POINTS HELP PLEASE! Complete the table and pattern. Determine the common difference. Write the explicit rule.

Cerrena [4.2K]

Answer:

See the answers below

Step-by-step explanation:

Nine

The first step is to find the common difference. That's found by using

Common Difference

t4 - t3

t4 = - 15

t3 = - 19

t4 - t3 = -15 - - 19

t4 - t3 = -15 + 19

t4 - t3 = 4

t1 = - 27 which is the first term.

Explicit formula

tn = a + (n - 1)*d

tn = - 27 + (n - 1)*4

t5 = -27 + (5 - 1)*4

t5 = -27 + 4*4

t5 = - 11

Recursive

tn = tn - 1 + 4

Ten

Common difference

t4 - t3

21 - 15

Common difference = 6

t2 = 33 - 6

t2 = 27

Explicit formula

tn = a + (n - 1)*d

tn = 33 + (n - 1)*6

Recursive Formula

tn = tn-1 + 6

There are too many answers between the 2 questions that the exact format can be followed and have it make sense. You are better off following each question and writing down the answers as you come to them.
