Answer:

No  

Step-by-step explanation:

Ariel will always have some money remaining.

We can demonstrate this by designing a table.

Each week she starts with a certain amount. At the end of the week she deducts 10 %, and the amount remaining becomes the starting amount for the next week.

<u>Week</u>  <u>Principal</u>  <u>Less 10 %</u>  <u>Remaining </u>

    1       600.00      60.00        540.00

    2      540.00      54.00        486.00

    3      486.00       48.60        437.40

    4      437.40       43.74         393.66

    5      393.66       39.37        354.28

    6      354.28       35.43         318.85

    7       318.85        31.89        286.97

    8      286.97       28.70        258.27

    9      258.27      25.83         232.44

  10      232.44      23.24         209.20

Ariel will still have $209.20 in her account after 10 weeks.

The legs of a right triangle measure 6 inches and 9 inches. If is the angle between the 6-inch leg and the hypotenuse, sin = ___
mr Goodwill [35]
First find the length of the hypotenuse using pythagorean theorem
<span>c^2 = 5^2 + 7^2
c^2 = 25 + 49
c^2 = 64
c=8 (take the square root in both sides)
Since sin = opposite/hypotenuse,
sin = 5/8 = 0.625</span>

For a data set of weights​ (pounds) and highway fuel consumption amounts​ (mpg) of eight types of​ automobile, the linear correl
Jobisdone [24]

Answer:

The P value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.3% which is not significant (at α = 0.05), so there is insufficient evidence to conclude that there is a linear correlation between weight and consumption. of highway fuel in cars.

Step-by-step explanation:

We have that the correlation coefficient shows the relationship between the weights and amounts of road fuel consumption of seven types of car, now the P value establishes the importance of this relationship. If the p-value is lower than a significance level (for example, 0.05), then the relationship is said to be significant, otherwise it would not be so, this case being 0.003 not significant.

The statement would be the following:

The P value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.3% which is not significant (at α = 0.05), so there is insufficient evidence to conclude that there is a linear correlation between weight and consumption. of highway fuel in cars.

Please help (puppy eyes)
-Dominant- [34]
First we have to find the decimal equivalent by dividing.
5 / 8 = 0.625

It can't be an Integer because decimals can't be intergers, so that's ruled out

It can't be repeating as it does end, so that's also ruled out

Since the decimal does end it can't be non-terminating, non-repeating

So the answer is Terminating Decimal by process of elimination
