The range of frequency is from 0.05 to 0.35 and a couple f the numbers aren't close to the other numbers 0.05 is not close to 0.21 or 0.35

so the outcomes do not appear to be equally likely, because of that a uniform probability model wouldn't be a good model.

The answer is A

Solve 3/3x + 1/x+4 = 10/7x solve for x

wariber [46]

Answer:

x = 14/3 + sqrt(217)/3 or x = 14/3 - sqrt(217)/3

Step-by-step explanation:

Solve for x:

x + 4 + 1/x = (10 x)/7

Bring x + 4 + 1/x together using the common denominator x:

(x^2 + 4 x + 1)/x = (10 x)/7

Cross multiply:

7 (x^2 + 4 x + 1) = 10 x^2

Expand out terms of the left hand side:

7 x^2 + 28 x + 7 = 10 x^2

Subtract 10 x^2 from both sides:

-3 x^2 + 28 x + 7 = 0

Divide both sides by -3:

x^2 - (28 x)/3 - 7/3 = 0

Add 7/3 to both sides:

x^2 - (28 x)/3 = 7/3

Add 196/9 to both sides:

x^2 - (28 x)/3 + 196/9 = 217/9

Write the left hand side as a square:

(x - 14/3)^2 = 217/9

Take the square root of both sides:

x - 14/3 = sqrt(217)/3 or x - 14/3 = -sqrt(217)/3

Add 14/3 to both sides:

x = 14/3 + sqrt(217)/3 or x - 14/3 = -sqrt(217)/3

Add 14/3 to both sides:

Answer: x = 14/3 + sqrt(217)/3 or x = 14/3 - sqrt(217)/3

Can you help with this please.

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - two points P ( 5 , 10 ) and R ( 12 , 14 ) on the cartesian plane

To find - distance between the two points

Using the distance formula ~

$\qquad\underline{d(PR) = \sqrt{( x_{2} - x_{1}) {}^{2} + ( y_{2} - y_{1}) {}^{2} }} \\ \\$

we have ,

$\longrightarrow x_{1} = 5 \\ \longrightarrow x_{2} = 12 \\ \\ \longrightarrow \: y_{1} = 10 \\ \longrightarrow \: y_{2} = 14$

substituting the values in the formula , we get

$d(PR) = \sqrt{(12-5) {}^{2} + (14-10) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{(7) {}^{2} + ( 4) {}^{2} } \\ \\ \implies \: d(PR) = \sqrt{49 + 16} \\ \\ \implies \: d(PR) = \sqrt{65} \\ \\ \implies \: d(PR) = 8.1 \: units \: (approx)$

hope helpful :)
