Answer:

$\frac{a^7}{b^6}$ (second option in your list)

Step-by-step explanation:

Notice that every base with negative exponent can be written with positive exponent on the opposite side of the fraction line, therefore:

The a to the exponent "-4" in the denominator can be written as a to the exponent 4 in the numerator, thus giving two bases a in the numerator, one with exponent 3 and another one with exponent 4 which combined with the rule of product of numbers with same base, leads to the addition ofthe exponents: a to the power 7 in the numerator.

We do something similar with the base b (which in the numerator appears with a "-1" in the exponent), we write it in the denominator with exponent "+1".

Therefore we end up with the following:

$\frac{a^3\,\,b^{-1}}{a^{-4}\,\,b^5}=\frac{a^3\,a^4}{b^5\,b^1} =\frac{a^7}{b^6}$

Write the sum of 18+27 as the product of their gcf and another sum

Georgia [21]

Factors of 18: 1; 2; 3; 6; 9; 18

Factors of 27: 1; 3; 9; 27

GCF(18; 27) = 9

18 + 27 = 9 × 2 + 9 × 3 = 9 × (2 + 3)

Given the function h(x) = x2 – 7x + 6, determine the average rate of change of

guapka [62]

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(h(7) - (h(3)) / (7 - 3)

h(7) = 7² - 7×7 + 6 = 49 - 49 + 6 = 6

h(3) = 3² - 7×3 + 6 = 9 - 21 + 6 = -6

7 - 3 = 4

(6 - -6)/4 = 12/4 = 3

the average change rate in that interval is 3 (or fully 3/1).

n 1 2 3 4 5 6

f(n) 1033 932 831 730 629 528

First term (a₁): 1033 Common difference (d): -101

Explicit rule: $a_{n} = 1134 - 101n$ Recursive rule: $a_{n} = a_{n-1} - 101$

$a_{n} = a_{1} + d(n - 1)$

$a_{n} = 1033 - 101(n - 1)$

$a_{n} = 1033 - 101n + 101$

$a_{n} = 1134 - 101n$

$a_{n} = a_{1} + d(n - 1)$

$a_{n} = -39 + 10(n - 1)$

The appropriate measure of central tendency is one that shows

difference and is suitable for a scale that is nominal.

Response:

The measure of central tendency to use is the mode.

<h3>How can the appropriate measure of central tendency be selected?</h3>

The mean is the sum of the measurements divided by the number count

of the plants.

The mode is the measurement that has the highest frequency.

The median is the measurement of the middle plant when arranged in a

given order according to size.

To argue that there is a difference between the plants, the measure of

central tendency to use is the mode, given that the data involves

measurements which can be expressed in a nominal scale.

Therefore;

The measure of central tendency that will be best for Mrs. Hull to use is the mode
