Solve (x to the fourth power - 6) ×7+3=

1 answer:

6 0

First multiply everything inside the brackets by seven
7x^4-42+3
Then solve what you can
7x^4-39
You an't solve it further. Is this what you mean? X to the fourth power?

Find the asymptotes of the function. Select all that apply.

devlian [24]

An asymptote is a vertical horizontal or oblique line to which the graph of a function progressively approaches without ever touching it.

To answer this question we observe the graph. All the values of x and y must be identified for which the graph of the function tends to infinity.

It is observed that these values are:

x = -1

x = 3

y = 0

The first two corresponds to the equations of a vertical line. The third corresponds to horizontal line, the axis of x. It can be seen that although the graph of the function is very close to these values, it never "touches" them

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900

ipn [44]

Answer:

The 34 week gestation's period baby weighs 0.11 standard deviations below the mean.

The 41 week gestation's period baby weighs 0.24 standard deviations below the mean.

A. The baby born in week 40 does since its z-score is smaller.

Step-by-step explanation:

Normal model problems can be solved by the zscore formula.

On a normaly distributed set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a value X is given by:

$Z = \frac{X - \mu}{\sigma}$

The zscore represents how many standard deviations the value of X is above or below the mean[/tex]\mu[/tex]. Whoever has the lower z-score weighs relatively less.

Find the corresponding z-scores.

Babies born after a gestation period of 32 to 35 weeks have a mean weight of 2800 grams and a standard deviation of 900 grams. A 34-week gestation period baby weighs 2700 grams.

Here, we have $\mu = 2800, \sigma = 900, X = 2700$ .

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{2700 - 2800}{900}$

$Z = -0.11$

A negative z-score indicates that the value is below the mean.

So, the 34 week gestation's period baby weighs 0.11 standard deviations below the mean.

Babies born after a gestations period of 40 weeks have a mean weight of 3400 grams and a standard deviation of 425 grams. A 40-week gestation period baby weighs 3300 grams.

Here, we have $\mu = 3400, \sigma = 425, X = 3300$
