1/8 of a number is -4200. What is the number: -33,600 -37 800 -42,000 -42,800

Sav [38]

Answer:

-33,600

Step-by-step explanation:

you already know that -4200 is 1/8 of the number so all you have to do is multiply -4200 by 8 and that gives -33,600.

Your friend asks you to help him with his dog grooming business and will pay you 4 4 pennies for the first job. You agree to hel

seraphim [82]

Answer:

You will receive 262,144 pennies after completing the 9th job.

Step-by-step explanation:

Given:

Payment for 1st job = 4 pennies

The payment is quadrupled after this for each job completed.

Payment after 2 jobs = 16 pennies

Payments after 3 jobs = 64 pennies

To find the number of pennies you will receive after the 9th job.

Solution:

Let $a_1$ represent the payment after 1st job.

$a_1=4$

$a_2=16$

$a_3=64$

The sequence is in geometric sequence with common ratio = 4

The n $th$ term of a geometric sequence is given as:

$T_n=a_1r^{(n-1)}$

For the sequence:

$a_1=4$

$n=9$

$r=4$

For the sequence we need the payment after 9th job. So, we are finding $T_9$ .

$T_9=4(4)^{(9-1)}$

$T_9=4(4)^{8}$

$T_9=4(65536)$

$T_9=262144$

Thus, you will receive 262,144 pennies after completing the 9th job.

The following dotplot shows the centuries during which the 11 castles whose ruins remain in Somerset, England were constructed.

Taking into account the rule 1.5 IQR, there aren't high outliers in the displayed data set.

Calculation of the Interquartile Range and the rule 1.5 IQR.

To calculate the Interquartile Range IQR, you must subtract the value of the first quartile Q1, to the third quartile Q3, as you can see in the formula below:

IQR = Q3 - Q1

Using the five-number summary, you can replace the formula:

IQR = 17 - 13

IQR = 4

Before to apply the rule 1.5 IQR, you must multiply the IQR by 1.5:

4 * 1.5 = 6

Now, to apply the rule you must add the value obtained (6), to the third quartile (17), if any data is over this, theoretically it's an outlier:

17 + 6 = 23 (As you do not have any data over this value, it is identified that there are no outliers in the upper section).

Finally, you must subtract the value obtained (6) to the first quartile (13), if any data is under this, theoretically it's an outlier:

13 - 6 = 7 (Since you don't have any castle data built before this century, there wouldn't be any theoretically outliers either).

By this reason, using the rule of 1.5 IQR, you can see there aren't outliers in the displayed data set.

In an inverse variation, y = 3 when x = 8. Write an inverse variation equation that shows

Klio2033 [76]

Answer:

y = 24/x

Step-by-step explanation:

An inverse variation equation is:

y = k/x

We have y = 3 when x = 8, find the coefficient k:

3 = k/8
k = 3*8
k = 24

The equation is:

y = 24/x

What set of reflections would carry triangle ABC onto itself?

crimeas [40]

The correct answer is y-axis, x-axis, y-axis, x-axis. The y-axis is the vertical line, and the x-axis is the horizontal line. If the triangle is in the upper right quadrant, and is reflected first over the y-axis, it will be in the upper left quadrant. Then, when the triangle is reflected again over the x-axis, it will be in the lower left quadrant, diagonal to the initial triangle. When the triangle is again reflected over the y-axis, it will be in the lower right quadrant, below the initial triangle. Finally, when the triangle is reflected over the x-axis, it will be on top of the original triangle in the upper right quadrant.
