Because the triangle is equilateral we know that z=60, therefore:

60=\frac{1}{3}x-7
67=\frac{x}{3}
67 \times 3 = x

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.

What is x, i can’t seem to figure it out
Orlov [11]

Answer:

x=12

Step-by-step explanation:

we know the shape is congruent because the 3angles are the same C is 60 for both. E and B are 100 (F rule). G and D are 120 (F rule)

ABCD is i thinkt the word is congruent to the other shape.

from EC and BC we see that bc is twice ec

therefore the scale is by two
