A media company wants to track the results of its new marketing plan, so the video production manager recorded the number of vie

Alisiya [41]

Answer:

$f(x)=5120(1.25)^{x}$

Step-by-step explanation:

As per the given question

As we know that

f(x) and x are related by following equation

$f(x)=a( {b})^{x}$

where

b is the common ratio

Now first we have to compute the value for b which are as follows

$\frac{6400}{5120}= 1.25$

$\frac{8000}{6400}= 1.25$

Like if we take the ratio by this method than it comes 1.25

Therefore the common ratio, b = 1.25

So,

a = 5,120

Hence, the equation which model the relationship between the number of weeks and the number of viewers is

$f(x)=5120(1.25)^{x}$

find the lower quartile for the data {47.2, 33.8, 43, 62, 5.8, 9, 61.4, 30.8, 68.2, 51.6, 13.2, 17.4, 64.2, 50.6, 29.4, 40.4}

mote1985 [20]

Answer:

The lower quartile is 23.4

Step-by-step explanation:

The given data are;

47.2, 33.8, 43, 62, 5.8, 9, 61.4, 30.8, 68.2, 51.6, 13.2, 17.4, 64.2, 50.6, 29.4, 40.4

Rearranging the data, we have;

5.8, 9, 13.2, 17.4, 29.4, 30.8, 33.8, 40.4, 43, 47.2, 50.6, 51.6, 61.4, 62, 64.2, 68.2

The lower quartile, Q₁, is the (n + 1)/4 th term which is (16 +1)/4 = 4.25th term

However since we have an even set of numbers, we place a separator at the middle and we look for the median of the left half as follows

5.8, 9, 13.2, 17.4, 29.4, 30.8, 33.8, 40.4║ 43, 47.2, 50.6, 51.6, 61.4, 62, 64.2, 68.2

We have two numbers (17.4 + 29.4) at the median of the left set of numbers, we find the average of the two numbers to get the lower quartile

The lower quartile is therefore = (17.4 + 29.4)/2 = 23.4.

Simplify:

Nesterboy [21]

Answer:

Step-by-step explanation:

$\sqrt{3}$ times $\sqrt{3}$ = 3 and $\sqrt{3}$ times x = $\sqrt{3}$ x

So that means that answer is 3+ $\sqrt{3}$ x which is C

What is the area of a triangle with 11 1/2 height and 14ft base

bezimeni [28]

Answer:

80.5 feet

Step-by-step explanation:

The formula for a triangle is 1/2 base times height. So it is 1/2 of 14 times 11 1/2. Which is also equal to 7 times 11 1/2. That equals 80.5. I hope this helps! Please mark me brainliest!
