4b) Work out the mean and standard deviation of the following: picture included
Jlenok [28]

Answer:

Yes, your simultaneous equations are correct;

Solve them like so:

170 + 1.6449σ = 180 - 0.8416

2.4865σ = 10

σ = 4.0217...

μ = 170 + 1.6449(4.0217...)

μ = 176.615...

MS is correct, you must've made an error in solving or rearranging

What type of expressions are in 3x–2y+7? I asked the wrong question beforehand.
nasty-shy [4]

Answer:

Step-by-step explanation:

3x+2y=7

Simplifying

3x + 2y = 7

Solving

3x + 2y = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

3x + 2y + -2y = 7 + -2y

Combine like terms: 2y + -2y = 0

3x + 0 = 7 + -2y

3x = 7 + -2y

Divide each side by '3'.

x = 2.333333333 + -0.6666666667y

Simplifying

x = 2.333333333 + -0.6666666667y
