What is each number in scientific notation?

Drag the answer into the box to match each number.

It is a geometric sequence since it has a common ratio. The next two terms are -80, 160

Let a sequence be:

          a(1), a(2), a(3), a(4), a(5), ...

To determine whether the sequence is an arithmetic sequence, or a geometric sequence, or neither, we need to check how its consecutive terms relate to each other.

The given sequence is:

-5,10,-20,40, . . .

a(2) - a(1) = 10 - (-5) = 15

a(4) - a(3) = 40 - (-20) = 60

So they don't have a common difference.

a(4)/a(3) = 40/(-20) = -2

a(3)/a(2) = -20/(10) = -2

a(2)/a(1) = 10/(-5) = -2

So they have a common ratio, i.e. r = -2.

Therefore, we can conclude that -5,10,-20,40, . . is a geometric sequence.

In a geometric sequence, the next term is equal to the previous term times the ratio.

We already have: -5,10,-20,40, ...

Hence:

Next term after 40 = 40 . (-2) = -80

Next term after -80 = -80 . (-2) = 160

Thus, the next two terms are -80, 160

The probability that Danielle, Nora, and Li will dive first, second, and third, respectively is 1/1320.

Since we are provided that in the meet, the orders of the drivers are randomly selected so,  the total number of drivers is: 12

let A be the event in that  Danielle was the first to dive.

    B be the event that  Nora been the second to dive.

and C is the event that Li has been the third to dive into.

P(A), probability of Danielle to dive first = 1/12

P(B), probability of Nora to dive second = 1/11

and P(C), probability of Li to dive in third = 1/10

So, the total probability that Danielle, Nora, and Li will dive first, second, and third, respectively = P(A) x P(B) x P(C)

Answer:

$10

Step-by-step explanation:

Let's begin with adding all of the items Greg bought.

36.62 + 11.25 + 17.75 = 65.62

Let the money paid to the cashier be x.

Now, it's stated he paid 60 dollars to the cashier and that he also got $4.38 back from the cashier.

Then, it must be that x=65.62+4.38

x=70

The money he borrowed from friend = 70-60=10

Therefore, the money Greg borrowed from his friend to pay for all the items is $10.

Greg borrowed $1.24 from his friend.

A single unit's value may be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary technique. We typically utilise this technique for math computations.

This approach allows us to calculate both the value of many units from the value of one unit and the value of many units from the value of one unit.

Given:

Greg bought a blanket for $36.62,

a flag for $11.25,

and a glove for $17.75.

Total expense of the objects he brought

= 36.62+ 11.25 + 17.75

= $65.62

He paid $60 then

=65.62 - 60 = $5.62 remaining

Also, he got $4.38 in change from the cashier

= 5.62 - 4.38

= $1.24.

Hence, Greg borrowed $1.24 from his friend.

The equation of the line in slope-intercept form passing through point (-3 , 1) and perpendicular to y = -(2/5)x - 4 is y = (5/2)x + 17/2

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula

y = mx + b

where m is the slope of the line

b is the y- intercept

If the line is perpendicular to y = -(2/5)x - 4, then their slopes are negative reciprocal of one another.

y = -(2/5)x - 4 : m = -2/5

m = 5/2

Substitute the values of the slope and the point to solve for the y-intercept, b.

y = mx + b

1 = 5/2(-3) + b

b = 17/2

Write the equation of the line by plugging in the value of the slope and y-intercept.

y = mx + b

y = (5/2)x + 17/2

In statistics, outlier refers to the data point from a given data set that differs significantly from the other data points.

One way to determine the outlier in a given data set is to calculate the interquartile range.

Q1 median = 4

Q3 median = 8

IQR = Q3 - Q1

IQR = 8 - 4

IQR = 4

4. Determine the outlier if

high outlier ≥ Q3 + (1.5 x IQR) = 8 + (1.5 x 4) = 14

The missing term of the sequence is - 4.9.

Here the sequence is -4.6, __, -5.2....

An arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

Here the sequence is in an arithmetic sequence, as there is a common difference between them.

The nth term of the sequence has a formula

[tex]a_{n}[/tex] = a + (n - 1) d

Here we know the 3rd term of the sequence so that we can find the common difference between them

[tex]a_{3}[/tex] = -4.6 +(3-1)d

-5.2 = -4.6 + 2d

0.6 = 2d

d = 0.3

So here the common difference is 0.3.

Now we have to find the 2nd term of the sequence,

[tex]a_{2}[/tex] = -4.6 + ( 2-1) 0.3

The first prime number is 2, taking the quotient:

80/2 = 40

So 2 is a factor.

Now we try to divide again by 2:

40/2 = 20

Now we can divide by 2 again:

20/2 = 10

And again:

10/2 = 5

And 5 is another prime number, so now we only can divide by 5:
