All cubic functions that are centered upon the x axis have a slope of 0 when x = 0

3 0

Answer:

• Slope is the derivative of the function:

{ \rm{f(x) =  {x}^{3}  + 3 {x}^{2} + 3x + 1 }} \\  \\ { \tt{ \frac{dy}{dx}  = 3 {x}^{2} + 6x + 3 + 0 }}

• At, x = 0

{ \tt{ \frac{dy}{dx}  = 3 {(0)}^{2}  + 6(0) + 3}} \\  \\ { \boxed{ \tt{slope = 3}}}

49/10 as a mixed number
Anni [7]
 ⇒ \frac{49}{10} 

\frac{49}{10} is a improper fraction. 
\frac{49}{10} as a mixed number would be 4 \frac{9}{10}

⇒10 x 4 = 40 
⇒40 + 9 = 49 

\frac{49}{10} = 4 \frac{9}{10} 

⇒ANSWER = 4 \frac{9}{10}

A survey of 35 people was conducted to compare their self-reported height to their actual height. The difference between reporte
Over [174]

Answer:

The test statistic is t = 3.36.

Step-by-step explanation:

You're testing the claim that the mean difference is greater than 0.7.

At the null hypothesis, we test if the mean difference is of 0.7 or less, that is:

H_0: \mu \leq 0.7

At the alternate hypothesis, we test if the mean difference is greater than 0.7, that is:

H_1: \mu > 0.7

The test statistic is:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, s is the standard deviation of the sample and n is the size of the sample.

0.7 is tested at the null hypothesis:

This means that \mu = 0.7

A survey of 35 people was conducted to compare their self-reported height to their actual height.

This means that n = 35

From the sample, the mean difference was 0.95, with a standard deviation of 0.44.

This means that X = 0.95, s = 0.44

Calculate the test statistic

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{0.95 - 0.7}{\frac{0.44}{\sqrt{35}}}

t = 3.36

The test statistic is t = 3.36.
