What's the product of 42⁄3 and 111⁄4 ?

svet-max [94.6K]

Answer:

(D) $52\frac{1}{2}$

Step-by-step explanation:

The given fractions are:

$4\frac{2}{3}and 11\frac{1}{4}$ .

We have to find the product of the given fractions, that is:

= $4\frac{2}{3}{\times}11\frac{1}{4}$

Simplifying the mixed fractions, we get

= $\frac{14}{3}{\times}\frac{45}{4}$

= $\frac{105}{2}$

Converting the answer into mixed fraction, we get

= $52\frac{1}{2}$

which is the required answer.

(1 point) A cup of coffee at 100 degrees celsius is put into a 30 degree celsius room when t=0. The coffee's temperature, f(t),

Lapatulllka [165]

Answer:your question seems incomplete but if you looking to find the resulting equation to solve for temperature at a particular time you can use this 28t^2

Step-by-step explanation:

F'(t) = 7(0.8)t

Integrating the RHS

Temp= integral of f'(t)= 28t^2

Therefore, T(°c)= 28t^2

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing

tester [92]

The length of pendulum is 2.485 feet

<h3><u><em>Solution:</em></u></h3>

Given that,

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth

<u><em>Therefore, the given formula is:</em></u>

$T=2\pi \sqrt{\frac{L}{32} }$

We have to find the length of pendulum that makes one full swing in 1.75 seconds

So the modify the given equation to find "L"

$T=2\pi \sqrt{\frac{L}{32} }\\\\ \sqrt{\frac{L}{32} }=\frac{T}{2 \pi}\\\\\text{Taking square root on both sides }\\\\\frac{L}{32} = \frac{T^2}{4 \pi^2}\\\\L = \frac{T^2}{4 \pi^2} \times 32\\\\L = \frac{T^2}{\pi^2 } \times 8$

Substitute T = 1.75 seconds and $\pi = 3.14$

$L = \frac{1.75^2}{3.14 \times 3.14} \times 8\\\\L = \frac{3.0625}{9.8596} \times 8\\\\L = 2.485$

Thus length of pendulum is 2.485 feet approximately

Assuming the population variances are unknown and equal, you wish to test whether the Group 1 population mean is equal to the Gr

Fantom [35]

Answer:

$n_1+n_2-2$

Step-by-step explanation:

If we had 2 independent samples with population variances unknown and equal and we want to compare the population mean between the both groups, the test statistic will be:

$t=\frac{x_1-x_2}{\sqrt{s_p^2(\frac{1}{n_1}+\frac{1}{n_2}) } }$

Where $s_p^2=\frac{(n_1-1)*s_1^2+(n_2-2)*s_2^2}{n_1+n_2-2}$

So, the t-student has $n_1+n_2-2$ degrees of freedom

Where $x_1$ and $x_2$ are the means of the groups, $n_1$ and $n_2$ are the size of the samples and $s_1^2$ and $s_2^2$ are the sample variances.
