Answer:

6.25cm²

Step-by-step explanation:

Hello!

The formula for the area of a triangle is $A = \frac12 b*h$

A = area
b = base
h = height

<h3>Solve</h3>

$A = \frac12 b*h$
$A = \frac12(5)*2.5$
$A = 2.5 * 2.5$
$A = 6.25$

The area of the triangle is 6.25 cm²

Answer:

Step-by-step explanation:

Hello!

apply distributive law

$a(b - c) = ab - ac$

2(3-8y)=2.3-2.8y

2.3=6
-2.8y= -16y

=6-16y

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
