Problem as entered: 15 - 191010
In 15, multiply the whole number, '1', by the denominator of the fraction, '10' to get '10'. This shows that the whole number represents
10.1010
To find the numerator when this mixed number is shown as an improper fraction, use addition.
10 + 5 = 15101010
In 19, multiply the whole number, '1', by the denominator of the fraction, '10' to get '10'. This shows that the whole number represents
10.1010
To find the numerator when this mixed number is shown as an improper fraction, use addition.
10 + 9 = 19101010
The addition is now simpler because the whole numbers have been eliminated, leaving only two fractions.
15 - 191010
Subtract the numerators.
-410
Simplify fraction -4/10 by dividing out the greatest common factor of 2 from the numerator and denominator.
-4 = -2105

Using a correlation Coefficient calculator, the correlation Coefficient, r for the data = 0.127

The test statistic :

T = r² / √(1 - r²) / (n - 2)

Sample size, n = 10

Hence,

T = 0.127² / √(1 - 0.127²) / (10 - 2)

T = (0.016129 / 0.3506905)

T = 0.3506905

The value of the test statistic to 2 decimal places is 0.35

Make m the subject in a(c+m)=2(c+3m)

Murrr4er [49]

Answer:

m = $\frac{2c-ac}{a-6}$

Step-by-step explanation:

distribute parenthesis on both sides

ac + am = 2c + 6m ( collect terms in m on left side )

subtract 6m from both sides

ac + am - 6m = 2c ( subtract ac from both sides )

am - 6m = 2c - ac ( factor left side )

m(a - 6) = 2c - ac ( divide both sides by (a - 6))

m = $\frac{2c-ac}{a-6}$

Please answer right away

Ilya [14]

Answer:

6.13

Step-by-step explanation:

Using Sine Law we know that

$\dfrac{a}{SinA}=\dfrac{b}{SinB}=\dfrac{c}{SinC}$

Using your figure let's assign sides and angles:

A=? B = 60° C = 70°

a = 5 b = ? c = x

If we put that into our formula:

$\dfrac{5}{Sin?}=\dfrac{?}{Sin60}=\dfrac{x}{Sin70}$

Notice that we have too many unknowns. We need to complete at least one ratio to do this, so how do we do this?

Notice we have 2 angles given, so we solve for the third angle. The sum of all angles in any triangle is always 180°

∠A + ∠B + ∠C= 180°

∠A + 60° + 70° = 180°

∠A + 130° = 180°

∠A = 180° - 130°

∠A = 50°

Now we can use this to solve for x.

$\dfrac{5}{Sin50}=\dfrac{x}{Sin70}\\\\\dfrac{(5)(Sin70)}{Sin50} = x\\\\\dfrac{4.6985}{0.7660}=x\\\\6.1338 =x$

So the closest answer would be 6.13
