A 11 gram sample of a substance that’s used to treat thyroid disorders has a k- value of 0.125

1 answer:

6 0

The substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125

<h3>What is exponential decay?</h3>

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have an exponential function:

$\rm N = N_oe^{-kt}$

Plug N = N⁰/2

$\rm N_o/2 = N_oe^{-kt}$

$\rm \dfrac{1}{2} = e^{-0.125t}$

Solving for t:

t = 5.54 ≈ 5.5 days

Thus, the substance's half-life is 5.5 days if the 11-gram sample of a substance that’s used to treat thyroid disorders has a k- the value of 0.125

What is the slope of the line that passes through the points (2, 3) and (8, 6)? 2/7 2 3/5 1/2

baherus [9]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

THe slope of a straight line is given by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Where

m is the slope

x_1 and y_1 are the first coordinate pair points [(2,3)]

x_2 and y_2 are the second coordinate pair point [(8,6)]

So, we know that:

x_1 = 2

x_2 = 8

y_1 = 3

y_2 = 6

Now we substitute and find the value of slope to be:

$m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{6-3}{8-2}\\m=\frac{3}{6}\\m=\frac{1}{2}$

Which expression has a coefficient of positive 1 for the the term n?

yanalaym [24]

Answer:

3n^2+n-2

Step-by-step explanation:

Coefficient is the number that we multiply an expression that contains a variable. In all the expressions above the variable is n.

Some examples:

Coefficient of n^2 is 1.

Coefficient of n in n^2+2n+1 is 2.

Solution:

In 5n^2+6n-1 the Coefficient of n is 6.

In 2n^2+5n+1 the Coefficient of n is 5.

In 40^2 - n +9 the Coefficient of n is - 1.

In 3n^2 +n - 2 the Coefficient of n is POSITIVE 1.

We tend to not write 1*n because 1*n=n.

Please! Help! The table below shows preferences of dancing or playing sports for male and female students:

Kryger [21]

Answer:

D) He calculated the joint relative frequency of female students who prefer playing sports. The conditional relative frequency for female students who prefer playing sports is 34%.

Step-by-step explanation:

The table is given as:

Playing sports Dancing Row totals

Male students 18 16 34

Female students 18 35 53

Column totals 36 51 87

We know that the joint relative frequency of an outcome is calculated as dividing the frequency of the outcome by the grand total.

Hence, when we divide the frequency of the female students who prefer playing sports i.e. 18 by the grand total i.e. 87 ; we obtain:

18/87=0.20689

which is approximately equal to 21%.

Hence, in order to calculate the conditional relative frequencies she should have divided the required frequency by the row total;.

Hence, here we divide the frequency of the female students who prefer playing sports i.e. 18 by the row total i.e. 53 ; we obtain:

18/53-0.3396

which is approximately equal to 34%.

Hence, option: D is correct.
