The average age of three girls is 37. One
girl is 28, another is 43. What is the
age of the Third girl ​

Answer:

420cm^3 (cubed) = volume when tripled

Step-by-step explanation:

1. when you multiply 7*4*5=140 (volume of the prism originally)

2. 140*3=420 (final answer)

Answer:

A. 140 cm

B. 3780 cm

Step-by-step explanation:

The volume formula for a rectangular prism is lwh, and 7 times 4 times 5 equals 140.

If you triple all those amounts, then you get 21 (7 times 3), 12 (4 times 3), and 15 (5 times 3), and when you multiply those you get 3780.

Which regression Equation would best model the data

Y=mx + c

You need to get this equation either using Micro soft excel(You can search for the steps online) or using the formula below

m= n(£xy) - (£x)(£y) / [ n(£x²) - (£x)²]

For C

C= £y - m(£x) / n

You'd need to draw a diagram and figure out these values

You need to be careful and know that £x² is not same as (£x)²

Know this to avoid mistakes.

Do this and fix your m and c values to get you regression line Equation.

Note: £ stands for Summation.

Evaluate those numbers like you would a statistical data.

Answer:

[tex]circumference = 2\pi \: r \\ = 2 \times 3.14 \times 6.1 \\ = 38.3 \: cm[/tex]

We have been given the radius of a circle is 6.1 cm. So, the Circumference of the circle is 38.3 cm.

Suppose that a considered circle has:

Circumference = C units

Radius = r units

Then, we get:

[tex]C = 2\pi r \: \rm units[/tex]

We have been given the radius of a circle is 6.1 cm.

The Circumference of the circle

[tex]C = 2\pi r \: \rm units[/tex]

[tex]C = 2\times 3.14 \times 6.1 \rm units\\\\C = 38.3cm[/tex]

Answer:

[tex]-\frac{3p^8}{4q^3}[/tex]

Step-by-step explanation:

[tex]\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}[/tex]  can be broken down into three fractions, coefficients, powers of p, powers of q.

[tex]-\frac{15}{20}\cdot\frac{p^{-4}}{p^{-12}}\cdot\frac{q^{-6}}{q^{-3}}[/tex]

Simplify the first fraction, then simplify the others by subtracting numerator exponents minus denominator exponents.

[tex]-\frac{3}{4} p^{-4-(-12)} q^{-6-(-3)} =-\frac{3}{4} p^8 q^{-3} = \alpha -\frac{3p^8}{4q^3}[/tex]

Answer:

1) We can use the following property to simplify the product of powers as follows:

[tex]a^{m}\cdot a^{n} = a^{m + n}[/tex], [tex]a\in \mathbb{R}[/tex], [tex]m,n\in \mathbb{Z}[/tex] (1)

Therefore, we have the following result:

[tex]10^{12}\cdot 10^{0} = 10^{12+0} = 10^{12}[/tex]

A) [tex]10^{12}[/tex] must be multiplied either by [tex]10^{0}[/tex] or by [tex]1[/tex] to get the same answer.

Step-by-step explanation:

1) We can use the following property to simplify the product of powers as follows:

[tex]a^{m}\cdot a^{n} = a^{m + n}[/tex], [tex]a\in \mathbb{R}[/tex], [tex]m,n\in \mathbb{Z}[/tex] (1)

Therefore, we have the following result:

[tex]10^{12}\cdot 10^{0} = 10^{12+0} = 10^{12}[/tex]

A) In addition, we can use this property:

[tex]\frac{a^{m}}{a^{n}} = a^{m-n}[/tex], [tex]a\in \mathbb{R}[/tex], [tex]m,n\in \mathbb{Z}[/tex]

We can apply the property mentioned above:

[tex]10^{12}\cdot 10^{0} = 10^{12}\cdot (10^{n-n}) = 10^{12}\cdot \left(\frac{10^{n}}{10^{n}} \right) = 10^{12} \cdot 1 = 10^{12}[/tex]

In consequence, we conclude that [tex]10^{0} = 1[/tex]. [tex]10^{12}[/tex] must be multiplied either by [tex]10^{0}[/tex] or by [tex]1[/tex] to get the same answer.

The answer would be B because the y intercept is how much he changes per hour

Answer:

Your answer should be C

Step-by-step explanation:

Letter A was tempting, but 120 for 1 hour. Then 180 for 2.5 means that is had a y intercept. So it couldn't be A. The other ones were easy to rule out because they only told a fraction of what was shown.
