Answer:

ZERO probability

Step-by-step explanation:

POSSIBLE combos 4 x 3 x 2 x1 = 24 possible combos

if it starts with 371 then the only choice for the 4th digit is 5

but no combo can have a 5 (per question)

so there are ZERO chances of this happening

the first table : y=4x
the second table: y=1.5x
the third table: y= 1.25x

if you want help on how to do it: plug each of those equations into the “desmos” graph! from looking at those table points (x,y) you can find which equation matches the table

for instance on table one: I put y=4x into desmos then looked at graph one, I chose the point (2,8) I went to 2 on the x axis and moved my finger up 8 and that point was directly on the line meaning that table matches the equation. be sure to also do the same thing with the other points to double check!

Answer:

The first table matches with the last equation.

The second table matches with the first equation.

The last table matches with the second equation.

Step-by-step explanation:

What I did was plug in the number in the x section for each table to see if the result of x times the number such as 4 resulted in the same number, y, that was paired with the x number based on the table.

Ex: Using table 1,

y=4x

y=4(2) --> I substituted the x for row 1 x in table 1

y=8

Check:

The first table shows that for row 1, the y was 8 so our match was correct.

Play soccer: _________67% / 33% / 100%

Do not play soccer:___ 45% / 55% / 100%

Total : _____________112% / 88% / 200%

Step-by-step explanation:

play soccer: total is 90, to find percentage :

60/90 = 0.6666666667 estimated = 0.67

0.67 x 100 = 67%
30/90 = 0.3333333333 estimated = 0.33

0.33 x 100= 33%

33% + 67% = 100%

don’t play soccer : total is 60, to find percentage:

27/60 = 0.45

0.45 x 100 = 45%

33/60= 0.55

0.55 x 100 = 55%

45% + 55% = 100%

Total for first column going down

67% + 45% = 112%

Second column going down

33% + 55%= 88%

Third column going down

100% + 100% = 200%

Third column going across

112% + 88%= 200%

Play soccer: 67% / 33% / 100%

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

What is expanded form?

The expanded form helps us to better understand a given number. Let us take an example of the number 875294831. It is difficult to understand this number. Here an expanded form helps us to understand each of the digits based on their place value. Let us take a simple number 324 and try to find its expanded form. 324 is written in expanded form as 300 + 20 + 4. It means there are three hundred, two tens, and 4 ones in this number.

Given number:

30452

The expanded form is

=3*10000+0*1000+4*100+5*10+2*1

So, there is no match for this.

If we write in words it can be written as thirty thousand, four hundred fifty-two.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.
