Answer:
mean = sum of the terms/total no. of terms
mean = (16+12+13+22)/4
mean = 63/4 or 15.75
Answer:
Step-by-step explanation:
Using the points (5, 1273) and (10, 2546), equation for the line is 5y = 1273x.
<h3>Define equation.</h3>
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.
Given,
Coordinates (5, 1273) and (10,2546)
For slope, m
m = y₂ - y₁/ x₂ - x₁
m = 2546 - 1273/10 -5
m = 1273/5
Equation in y = mx form,
y = 1273/5 x
Cross multiplying,
5y = 1273x

Answer:
yes he is correct. he spent 125% more time
Step-by-step explanation:
his original time spent was 20 hours
he spent a new time which is 25 hours
increased time = 25- 20 = 5 hours
% increase = increase/ original ×100%
%increase = 5/ 20 ×100%
= 1/4 ×100%
= 25%
total increment = 100 + 25 =125%
Answer:
5 birds flew away
Step-by-step explanation:
1/6x6=1
( 1 bird flew away)
so, 6-1=5
