Answer:

2x + 2y = 4  does not belong

Step-by-step explanation:

2x + y = 4     → <u>y = -2x + 4</u>

y = -2x + 4    → <u>y = -2x + 4</u>

f(x) = -2x + 4 → <u>y = -2x + 4</u>

2x + 2y = 4   → <u>y = -x + 2</u>

Specific gravity will tell you a fraction of how much
Nikolay [14]

The value 0.92 indicates the relative density of the ice.

Data;

  • Density = 0.92g/ml
  • Specific gravity = 0.92

<h3>Specific Gravity</h3>

Specific gravity of a substance is defined as the relative density of substance. This can be further said to be the ratio between the density of a substance to the density of the reference substance.

mathematically;

relative density = \frac{density of substance}{density of reference}

The value 0.92 indicates the relative density of the ice.

Last week Andi had exams in Chemistry and in Spanish. On the chemistry exam, the mean was µ = 30 with σ = 5, and Andi had a scor
ValentinkaMS [17]

Answer:

Chemistry

Step-by-step explanation:

To solve the above question, we use the z score formula

Andy took two Exams, Chemistry and Spanish. So we find the z score for both exams.

a) Chemistry Exam

On the chemistry exam, the mean was µ = 30 with σ = 5, and Andi had a score of X = 45

z-score is given as: z = (x-μ)/σ

where x is the raw score,

μ is the population mean

σ is the population standard deviation

z = (x-μ)/σ

z = (45 - 30)/5

z = 15/5

z = 3

b) On the Spanish exam, the mean was µ = 60 with σ = 6 and Andi had a score of X = 65.

z-score is given as: z = (x-μ)/σ

where x is the raw score,

μ is the population mean

σ is the population standard deviation

z = (x-μ)/σ

z = (65 - 60)/6

z = 5/6

z = 0.8333333333

Comparing the z score of both Exams,

Andy had a z score of 3 in the Chemistry exam and 0.8333333333 in the Spanish exam.

Therefore, Andy should be expecting a better grade in the Chemistry exam because his z score in the Chemistry exam was higher than that of the Spanish exam.
