-9x+5<17 AND 13x+25<-1

fgiga [73]

Answer:

x < -3 1/2 or 3.5

Step-by-step explanation:

-9x + 5 < 17

13x +25 < -1

If we add the 2 equations together, we will have

4x + 30 < 16

4x < 16 - 30

4x < -14

Divide both sides by 4

x< -14/4

x < -3 1/2 or 3.5

In a continuous series, mean(x) = 80, assumed mean(A) = 60 and<br>EF=40 then find the value of EFd.

Aneli [31]

Using the given information, the value of Σfd is 800

<h3>Calculating mean using Assumed mean </h3>

From the question, we are to determine the value of Σfd

The formula for mean, using the assumed mean method is given by

$\bar x = A + \frac{\sum fd}{\sum f}$

Where $\bar x$ is the mean

A is the assumed mean

From the given information,

$\bar x = 80$

$A = 60$

$\sum f = 40$

Putting the parameters into the equation, we get

$80 = 60 + \frac{\sum fd}{40}$

$80-60 = \frac{\sum fd}{40}$

$20 = \frac{\sum fd}{40}$

$\sum fd = 20 \times 40$

$\sum fd = 800$

Hence, the value of Σfd is 800
