It took the football team 5 h to travel from Titletown, a total distance of 1320 km. Part of the trip was by bus and the remaind

inn [45]

Answer:

It took 2 hours by plane

Step-by-step explanation:

let bus is represented by x and plane is represented by y

the total distance of bus and plane will be represented by equation:

40 x + 600 y = 1320 (1)

the total time taken by bus and plane will be represented by:

x + y = 5 (2)

solving equations (1) and (2) simultaneously:

Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)

40 x + 600 y = 1320

40 x + 40 y = 200

_______________

560 y = 1120

y = 1120/ 56

y= 2

since plane is represented by y so, the time they spent travelling by plane is 2 hours.

The following observations on degree of polymerization for paper specimens are used to estimate the true average degree polymeri

marshall27 [118]

Answer:

The answer is in the explanation

Step-by-step explanation:

Mean value = $\bar x$ = 438

(a) The data appeared to be centered towards 438.

There are little or no skew.

There is no outliers.

(b) yes

95% confidence interval = $+- t_{df} * s\sqrt{n}$

$438 +- 2.12 * 14.8955 /\sqrt{17}$ =

= (430.3415, 445.6585)

(d) Test statistic

t = $(438 - 450)/{14.8955\sqrt17} }$

t = -3.3216

p -value is correctly given in option b.

No, 450 is not a plausible valaue.

Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE

Furkat [3]

Answer:

x = -6 and x = 4

Step-by-step explanation:

In math, the critical points of a function are the points where the derivative equals zero.

So, first we will find the derivative of the function. The derivative is:

$f'(x)=3x^2 +6x-72$

Now, we are going to make the derivative equal zero and find the answers of the equation.

$3x^2 +6x-72=0\\3(x^2 +2x-24)=0\\3(x+6)(x-4)=0\\$

So we have that the critical points are the answers to this equation:

$x+6= 0 \\x= - 6$

and

$x-4=0\\x=4$

Thus, the critical points are x=-6 and x=4
