If f(6) if f(x)=x^2 / 3 + x

MakcuM [25]

Answer:

1) If the function is $f(x)=\frac{x^{2}}{(3+x)}$ , $f(6)=4$

2) If the function is $f(x)=x^{(2/3)}+x$ , $f(6)=9.30$

3) If the function is $f(x)=\frac{x^{2}}{3}+x$ , $f(6)=18$

Step-by-step explanation:

To solve this problem you must apply the proccedure shown below:

f(6) means that you must substitute x=6 into the function above.

1. If the given the function $f(x)=\frac{x^{2}}{(3+x)}$ , you obtain:

$f(6)=\frac{6^{2}}{(3+6)}=4$

2. If the function is $f(x)=x^{(2/3)}+x$

Then:

$f(6)=6^{(2/3)}+6=9.30$

3. If the function is $f(x)=\frac{x^{2}}{3}+x$

Then:

$f(6)=\frac{6^{2}}{3}+6=18$

What is the point-slope form of a line that has a slope of 5 and passes through the point (3, –4)?

Alinara [238K]

Answer:

y + 4 = 5(x - 3)

Step-by-step explanation:

In the Point-Slope Formula, y - y₁ = m(x - x₁), all the negative symbols give the OPPOSITE terms of what they really are.

Assume that adults have IQ scores that are normally distributed with a mean of mu equals 105 and a standard deviation sigma equa

kondor19780726 [428]

Answer: 0.6827

Step-by-step explanation:

Given : Mean IQ score : $\mu=105$

Standard deviation : $\sigma=15$

We assume that adults have IQ scores that are normally distributed .

Let x be the random variable that represents the IQ score of adults .

z-score : $z=\dfrac{x-\mu}{\sigma}$

For x= 90

$z=\dfrac{90-105}{15}\approx-1$

For x= 120

$z=\dfrac{120-105}{15}\approx1$

By using the standard normal distribution table , we have

The p-value : $P(90$

$P(z$

Hence, the probability that a randomly selected adult has an IQ between 90 and 120 =0.6827
