Answer: $\frac{19}{14}$ in improper form and $1\frac{5}{14}$ in mixed fraction form.

Step-by-step explanation: $\frac{6}{7}$ + $\frac{1}{2}$ = ? First you have to find the LCM (Least Common Multiple) of 7 and 2; also known as the LCD (Least Common Denominator). The LCM of 7 and 2 is 14 so you have to multiply both of the fractions by the number that equals 14, remember to multiply it for the numerator too. $\frac{6}{7}$ x $\frac{2}{2}$ = $\frac{12}{14}$ Then $\frac{1}{2}$ x $\frac{7}{7}$ = $\frac{7}{14}$ Now you add $\frac{12}{14}$ and $\frac{7}{14}$ together. You leave the denominator as 14 because you found the LCD of 7 and 2 already, so you add 12 and 7 together which gives you 19. The answer would be $\frac{19}{14}$ in improper fraction form and $1\frac{5}{14}$ in mixed fraction form.

The sum of the fraction 6/7 and 1/2 is 19/14

<h3>How to add fractions</h3><h3 />

Given:

sum of 6/7 and 1/2

Sum means addition(+)

= 6/7 + 1/2

The least common denominator is 7 × 2 = 14

= 6/7 + 1/2

= (12+7) / 14

= 19/14

Therefore, the sum of 6/7 and 1/2 is 19/14

What is the equation of the line in standard form? 3x−y=−6 3x + y = 6 x + 6y = 9 x−6y=−9

lisabon 2012 [21]

The standard form: Ax + By = C

3x - y = -6 YES - A = 3, B = -1, C = -6

3x + y = 6 YES - A = 3, B = 1, C = 6

x + 6y = 9 YES - A = 1, B = 6, C = 9

x - 6y = -9 YES - A = 1, B = -6, C = -9

Use the given values of n= 93 and p= 0.24 to find the minimum value that is not significantly low, μ- 2σ , and the maximum val

allsm [11]

Answer:

The answer is "Option a".

Step-by-step explanation:

$n= 93 \\\\p= 0.24\\\\\mu=?\\\\ \sigma=?\\\\$

Using the binomial distribution: $\mu = n\times p = 93 \times 0.24 = 22.32\\\\\sigma = \sqrt{n \times p \times (1-p)}=\sqrt{93 \times 0.24 \times (1-0.24)}=4.1186$

In this the maximum value which is significantly low, $\mu-2\sigma$ , and the minimum value which is significantly high, $\mu+2\sigma$ , that is equal to:

$\mu-2\sigma = 22.32 - 2(4.1186) = 14.0828 \approx 14.08\\\\\mu+2\sigma = 22.32 + 2(4.1186) = 30.5572 \approx 30.56$

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use PT to solve for the missing length.

Step 2: Identify Variables

Leg a = 6

Leg b = x

Hypotenuse c = √89

Step 3: Solve for x

Set up equation: 6² + x² = (√89)²
Isolate x term: x² = (√89)² - 6²
Exponents: x² = 89 - 36
Subtract: x² = 53
Isolate x: x = √53
