Answer:
21
Step-by-step explanation:
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
so...
15 + 6 = 21
Answer:
Rate
Step-by-step explanation:
Rate is basically also a ratio. but it is the comparing of two different quantities with different units.
As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.
for example:
When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.
20 meters : 15 seconds
thus the lowest form of this relationship will be:
4 meters : 3 seconds
when i write it in Decimal form it becomes :
Ans : 1.33 meters/second (Distance per unit time)
As this ratio have remaining units thus it is referred to as "RATE".

Answer is option a ) 0.53
Step-by-step explanation:
slope = 
Given that a pediatrician wishes to study how the average weight Y (in kilograms) of children changes during the first year of life. He plots these averages versus the age X (in months) and decides to fit a least-squares regression line to the data with X as the explanatory variable and Y as the response variable.
He finds the following quantities:
r = correlation between X and Y= 0.84
x = mean of the values of X = 5.69
y = mean of the values of Y = 6.26
S_x = standard deviation of the values of X = 3.23
s_y = standard deviation of the values of Y = 2.04
Using the formula for slope given above substitute to get
round off to 0.53
Answer is option a ) 0.53
Answer: Jordan
Step-by-step explanation:
Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
