To find the percentage, we simply do:
240 / 30 x 100
= 800%
The statement says what percent OF 30 IS 240, not what percent OF 240 is 30. Because you divided 30 by 240 and multiplied by 100, you got 12.5%. It is actually 800%

Which equation represents a proportional relationship? A) y = 3x 4 B) y = 3 4x C) y = 3x 4 + 1 D) y = 3 4x + 1
lesantik [10]

Answer:

A. y = 3x/4

Step-by-step explanation:

 a proportional relationship between x and y is a straight line passing through the origin (0, 0).

The equation must be in the form y = kx.

y = 3x/4

y = 3/4x

Provide the reflected ordered pair for each of the given ordered pairs. Reflect the ordered pair ( − 4 , 5 ) (-4, 5) across the
levacccp [35]

Answer:

a) (4,5)

b) (0,-3)

Step-by-step explanation:

We have to perform the following reflection over given ordered pair.

a) Reflect the ordered pair (-4,5) across the y-axis

Reflection over y-axis:

r: (x,y)\rightarrow (-x,y)

Thus, (-4,5) will be reflected over y-axis as

r: (-4,5)\rightarrow (-(-4),5) = (4.5)

b) Reflect the ordered pair (0,3) across the y-axis

Reflection over x-axis:

r: (x,y)\rightarrow (x,-y)

Thus, (0,3) will be reflected over x-axis as

r: (0,3)\rightarrow (0,-(3)) = (0,-3)

A simple random sample of size n=10 is obtained from a population that is normally distributed with a mean of 40 and a standard
Eva8 [605]

Yes, the sampling distribution is normally distributed because the population is normally distributed.

A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.

A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.

Solution :

mean = μ40

standard deviation σ σ= 3

n = 10

μx =  40

σ x = σ√n =  3/√10  = 0.9487

μ x =  4σ\x = 0.9487

σx = 0.9487

Yes, the sampling distribution is normally distributed because the population is normally distributed.
