Answer:

The answer is "6.212".

Step-by-step explanation:

A few of the information is missing throughout this question, therefore the solution could be defined as follows:

In this question, the value of its testing dataset to determine unless the connection is clinically meaningful from both the Means and standard deviations is 6.212 from its test statistics.

Answer:

Yes, she is correct

Step-by-step explanation:

All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.

Price of one pound of mercury

[tex]x=\$ 2.06[/tex]

Price of one cubic inch of mercury

[tex]z=\$1.0[/tex]

Step-by-step explanation:

From the question we are told that

Mass of mercury [tex]M= 76pound[/tex]

Price of 76 pound [tex]P=\$162[/tex]

Density of mercury is [tex]\rho=13.534 g/cm3.[/tex]

Generally the cost of one pound of Mercury x will mathematically be given as

 [tex]x=\frac{162}{76}[/tex]

 [tex]x=\$ 2.13[/tex]

Generally the cost of one gram of Mercury G will mathematically be given as

 [tex]1pound = 453.92g[/tex]

 [tex]G=2.06/453.93\\G=\$4.6*10^-^3[/tex]

Generally the cost of one cubic centimetre of Mercury c will mathematically be given as

 [tex]13.5= 1cm^3\ of\ Mercury[/tex]

 [tex]c=\$6.33*10^-^2[/tex]

Generally the cost of one cubic inch of Mercury z will mathematically be given as

 [tex]z=0.0614*16.4[/tex]

 [tex]z=\$1.0[/tex]

Answer:

$19.03

Step-by-step explanation:

Okay, this is a standard percentage problem, so learning how to do this is necessary. First, we have to find what 6% of $17.95 is, since of is our keyword and that means to multiply, and percentages turn into decimals:

17.95 x 0.06 = 1.08

So we have our tax, then we have to add that to our original price to get the whole thing:

17.95 + 1.08 = 19.03

So the total sale price is $19.03

Answer:

Kiara is correct

.............

Kiara says that the slope of the line between points B and C is the same as the slope of the line between points A and B is Correct.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

From the figure

Slope between A and B = rise/ run 3/3 = 1

and, slope between B and C = 5/5 = 1

So, the slope between A and B is same as the slope between B and C.

Hence, Kiara has correct statement.

constant of proportionality

Step-by-step explanation:

Assuming that we have two proportional quantities; one is x and one is y.

If we know whether the relationship between them is direct or inverse proportion, then the ratio of the two quantities y/x gives us a constant generally known as the constant of proportionality.

Answer:

Step-by-step explanation:

we have a rectangle, and the perimeter P=70

P=2L+2W

P=2(5x-7)+2(3x+2)=10x-14+6x+4=16x-10

16x-10=70

16x=70+10=80

16x=80

x=5

Step-by-step explanation:

How many more votes the winner received than the loser can be thought of as the distance between the two numbers of votes on the number line.

Hint #22 / 5

The distance between two numbers is equal to the absolute value of their difference.

For example, | a - b|∣a−b∣vertical bar, a, minus, b, vertical bar is the distance between aaa and bbb.

Hint #33 / 5

We want to find the distance between \blue{w}wstart color #6495ed, w, end color #6495ed and \pink{v}vstart color #ff00af, v, end color #ff00af.

Hint #44 / 5

The distance between \blue{w}wstart color #6495ed, w, end color #6495ed and \pink{v}vstart color #ff00af, v, end color #ff00af is |\blue{w} - \pink{v}|∣w−v∣vertical bar, start color #6495ed, w, end color #6495ed, minus, start color #ff00af, v, end color #ff00af, vertical bar or |\pink{v}-\blue{w}|∣v−w∣vertical bar, start color #ff00af, v, end color #ff00af, minus, start color #6495ed, w, end color #6495ed, vertical bar.

Hint #55 / 5

\left\lvert \blue w- \pink v\right\rvert∣w−v∣open vertical bar, start color #6495ed, w, end color #6495ed, minus, start color #ff00af, v, end color #ff00af, close vertical bar always represents how many more votes the winner received than the loser.

The expressions that always represents how many more votes the winner received than the loser will be Choice b .∣w−v∣

Cicero and Themistocles run for the same political office. Cicero received www votes in the election and Themistocles received vvv votes.

This can be thought of as the distance between the two numbers of votes on the number line.

Here, The distance between two numbers is equal to the absolute value of their difference.

For example; | a - b| vertical bar, a, minus, b, vertical bar is the distance between aaa and bbb.

Options (2), (4) and (6)

Step-by-step explanation:

Option (1)

[tex]8^{-1}=\frac{1}{8}[/tex]

Not equivalent to [tex]\frac{1}{81}[/tex].

False.

Option (2)

[tex]9^{-2}=\frac{1}{9^2}[/tex]

      [tex]=\frac{1}{81}[/tex]

True.

Option (3)

[tex]\frac{9^{8}}{9^{4}}=9^{(8-4)}[/tex]

    [tex]=9^{4}[/tex]

False.

Option (4)

[tex]\frac{9^8}{9^{10}}=9^{8-10}[/tex]

     [tex]=9^{-2}[/tex]

     [tex]=\frac{1}{81}[/tex]

True.

Option (5)

[tex]9^{-6}9^{3}[/tex] = [tex]9^{-6+3}[/tex]

         = [tex]9^{-3}[/tex]

         = [tex]\frac{1}{9^3}[/tex]

         = [tex]\frac{1}{729}[/tex]

False

Option (6)

          [tex]=9^{-2}[/tex]

          [tex]=\frac{1}{9^2}[/tex]

           [tex]=\frac{1}{81}[/tex]

True.

Therefore, Options (2), (4) and (6) are the correct options.

Applying the negative exponent rule of power, the expressions that are equivalent to the given expression, 1/81, are: B, D, and F.

The negative exponent rule states that: [tex]a^{-n} = \frac{1}{a^n}[/tex].

Thus, given the expression, 1/81, it can be rewritten or simplified as follows:

1/81 = [tex]81^{-1} = 9^{-2}[/tex] = [tex]\frac{9^8}{9^{10}}[/tex] = [tex]9^5 \times 9^{-7}[/tex]

The expressions that will be equivalent to 1/81 can be expressed, based on the negative exponent rule of power, as:

[tex]9^{-2}, \frac{9^8}{9^{10}} , 9^5 \times 9^{-7}[/tex] (option B, D, and F).
