Answer:

x=7

Step-by-step explanation:

3x-5/4=x+1/2

3x-5=2(x+1)

3x-5=2x+2

3x=2x+2+5

3x=2x+7

3x-2x=7

x=7

<h2>x = 7</h2>

Step-by-step explanation:

\frac{3x - 5}{4}  =  \frac{x + 1}{2}  \\ 2(3x - 5) = 4(x + 1) \\ 6x - 10 = 4x  +  4 \\ 6x - 4x = 4 + 10 \\ 2x = 14 \\  \:  \:  \: x =  \frac{14}{2}  \\ x = 7

Use z scores to compare the given values.
Effectus [21]

Answer:

The answer is given below

Step-by-step explanation:

Z score is used to measure by how many standard deviations the raw score is above or below the mean. It is given by the formula:

z=\frac{x-\mu}{\sigma}\\ \\Where\ \mu=mean, x=raw\ score, \sigma=standard\ deviation

For the male:

μ = 3259.8 g, σ = 869.7 g

Hence for a male who weighs 1600 g, the z score is:

z=\frac{x-\mu}{\sigma} =\frac{1600-3259.8}{869.7}=-1.91

For the female:

μ = 3000.9 g, σ = 550.8 g

Hence for a female who weighs 1600 g, the z score is:

z=\frac{x-\mu}{\sigma} =\frac{1600-3000.9}{550.8}=-2.54

Since the z score for the male is z= -1.91 and the z score for the female is z= -2.54 the  male has the weight that is more extreme.

Answer:

  g(x) = x -1

Step-by-step explanation:

Translation of a function by (right, up) = (h, k) is accomplished by ...

  g(x) = f(x -h) +k

Here the translation is 4 units left, so h=-4 and k=0. This means ...

  g(x) = f(x +4) = (x+4) -5

  g(x) = x -1
