Algebra I

Terms/Coefficients
Coordinates (x, y)
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-4x + 16 = y

2x - 32 = 2y

Step 2: Solve for x

Substitution

Substitute in y: 2x - 32 = 2(-4x + 16)
Distribute 2: 2x - 32 = -8x + 32
[Addition Property of Equality] Add 8x on both sides: 10x - 32 = 32
[Addition Property of Equality] Add 32 on both sides: 10x = 64
[Division Property of Equality] Divide 10 on both sides: x = 32/5

Step 3: Solve for y

Define original equation: -4x + 16 = y
Substitute in x: -4(32/5) + 16 = y
Multiply: -128/5 + 16 = y
Add: -48/5 = y
Rewrite/Rearrange: y = -48/5

When testing a hypothesis about a single mean, if the sample size is 51 and the population standard deviation is known, the corr

choli [55]

Answer:

z-statistic

Step-by-step explanation:

We have to identify the correct test statistic to use with the given conditions.

If the sample size is larger than 30, then the sample is considered to be large.
We are given a sample size of 51, which is a a large sample.
Also, the population standard deviation is known.
Thus, we use the z-statistic when testing a hypothesis about a single mean.
Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} }$
