There are 6 nickels and 14 pennies.
There are 20 total coins.
The ratio of nickels to coins is 6:20.
Both of these are divisible by 2, so we can reduce this to 3:10.
Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27
The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the points (-4, -6) and (2, 6). Substitute:
Put the coordinates of the point (2, 6) to the equation of a line:
<h3>Answer: y = 2x + 2</h3>
