The times for five sprinters in a 50 meter dash were 6.72 seconds 6.4 seconds 6.08 and 7.03 seconds in 6.75 seconds right these

andreev551 [17]

Answer:

Fastest to slowest = 6.08 > 6.4 > 6.72 > 6.75 > 7.03

Step-by-step explanation:

The person who completes the 50-meter race within the shortest possible time is the fastest sprinter. Here, the third sprinter crossed the line in 6.08 seconds, whereas the 4th sprinter crossed the line in 7.03 seconds. That is why the third sprinter has won the race, and he becomes the fastest. On the contrary, the fourth person takes the most time to complete the race, meaning he is the slowest.

Compute the integral (a) int sin (pi x) dx by letting u = pi x. (b) int e^(x/2) dx by letting u = x/2. Show that you got the cor

Maslowich

Answer:

(a) $\int sin(\pi x) dx$ $=-\frac {cos \pi x}{\pi}+c$

(b) $\int e^\frac{x}{2} dx$ $=2e^\frac{x}{2}+c$

Step-by-step explanation:

(a)

$\int sin(\pi x) dx$

Let u = π x

differentiating with respect to x

du = π dx

$\Rightarrow dx=\frac{du}{\pi}$

Putting the value of x and dx

$=\int sin u \frac{du}{\pi}$

$=\frac{-cos u}{\pi}+c$ [ c is an arbitrary constant]

Now putting the value of u

$=-\frac {cos \pi x}{\pi}+c$

(b)

$\int e^\frac{x}{2} dx$

Let $u=\frac{x}{2}$

differentiating with respect to x

$du= \frac{1}{2} dx$

2du = dx

Putting the value of x and dx

= $\int e^u.2.du$

= $2e^u +c$

Now putting the value of u

$=2e^\frac{x}{2}+c$ [ c is an arbitrary constant]

Answer:

The p-value is $p-value = 0.013167$

Step-by-step explanation:

From the question we are told that

The population mean is $\mu$ = 200 milligrams

The sample size is $n = 70$

The sample mean is $\= x = 205.7$

The sample standard deviation is $\sigma = 21 \ milligram$

Generally the Null hypothesis is mathematically represented as

$H_o : \mu = 200$

The Alternative hypothesis is

$H_a : \mu < 200$

The test statistics is mathematically represented as

$t_s = \frac{\= x - \mu }{\frac{\sigma}{\sqrt{n} } }$

substituting values

$t_s = \frac{ 205.7 - 200 }{\frac{21}{\sqrt{70} } }$

$t_s = 2.270$

Now the p-value is mathematically represented as

$p-value = P(Z \le t_s )$

substituting values

$p-value = P(Z \le 2.270 )$

Using the Excel function[=NORMDIST(2.270)] to calculate the p-value we obtain that

$p-value = 0.013167$
