For the data set given below, calculate the 70th percentile. (answer with an integer or decimal.) 24 45 52 78 90 120 34 67 111 1

Mashutka [201]

we know that

To calculate the percentile of a data set, we should first order all the values in the data set from smallest to largest.

[10,24,34,45,52,67,78,90,111,120]

As their are
10
data points

and
70% of this is
(70/100)*10=7

Take the index and the next greatest number and find the average.

Because,the index is a whole number

[10,24,34,45,52,67,78,90,111,120]

(78+90) /2=84

70th
percentile is equal to 84

the answer is

The 70th percentile is 84

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (2, 720)(2,720).

Nataliya [291]

Answer:

The exponential function that goes through $(x_{1},y_{1}) = (0,20)$ and $(x_{2}, y_{2}) = (2,720)$ is $y = 20\cdot 6^{x}$ .

Step-by-step explanation:

Let be an exponential function of the form $y = a\cdot b^{x}$ that goes through $(x_{1},y_{1}) = (0,20)$ and $(x_{2}, y_{2}) = (2,720)$ . Then, we have the following system of equations:

$20 = a\cdot b^{0}$ (1)

$720 = a\cdot b^{2}$ (2)

By dividing (2) by (1), we obtain the value for $b$ :

$\frac{720}{20} = b^{2}$

$b = \sqrt{\frac{720}{20} }$

$b = 6$

And the value for $a$ is found by (1):

$a = 20$

The exponential function that goes through $(x_{1},y_{1}) = (0,20)$ and $(x_{2}, y_{2}) = (2,720)$ is $y = 20\cdot 6^{x}$ .
