Which eqation is equivalent to 3x + 4y = 15

liubo4ka [24]

Answer:

$y=\frac{15-3x}{4}$

Step-by-step explanation:

Here we are given an equation in x and y and we are required to solve it for y

we have

$3x+4y=15$

subtracting 3x from each sides we get

$3x-3x+4y=15-3x$

$4y=15-3x$

now we divide both sides by 4 we get

$\frac{4y{4}=\frac{15-3x}{4}$

$y=\frac{15-3x}{4}$

Hence A) is our right answer.

If IQ scores are normally distributed with a mean of 100 and a standard deviation of 15, what is the mean IQ score after the sco

lianna [129]

Answer:

$\mu = 0 , \sigma=1$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable that represent the IQ scores of a population, and for this case we know the distribution for X is given by:

$X \sim N(100,15)$
