Answer:
1.37g/ml
Step-by-step explanation:
What is density?
Density (ρ) is simply the mass (m) per given volume (V) of a substance
The formula is therefore:
ρ = m/V
Just as speed is distance covered per a given period of time;
We have a mass and we have a volume, all we need to do is plug into the formula:
ρ = 5.788/(4.22)
ρ = 1.37156398104 → 1.37 (rounded to 3 significant figures)
Finding the units is easy, the mass is in g and the volume is in ml and the mass is divided by volume so the units are: g/ml
Answer:There is a relationship between study hours and test score. As the hours of studying increase, the test scores increase.
Step-by-step explanation:
From the given scatterplot in which Mackenzie investigated the relationship between the number of hours studying and the test score for some of the students in her class.
We can see that the dots are increasing in the right and go upward with respect to time.
It shows there is a relationship between the test score and hours of studying.
As the hours of studying increase, the test scores increase .
6h-4
1. Substitute 5 for h
6(5)-4
30-4 =26
Answer:
The value of annuity is 
Step-by-step explanation:
From the question we are told that
The periodic payment is 
The interest rate is 
Frequency at which it occurs in a year is n = 4 (quarterly )
The number of years is 
The value of the annuity is mathematically represented as
![P_v = P * [1 - (1 + \frac{r}{n} )^{-t * n} ] * [\frac{(1 + \frac{r}{n} )}{ \frac{r}{n} } ]](https://tex.z-dn.net/?f=P_v%20%20%3D%20%20P%20%2A%20%20%5B1%20%20-%20%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%20%29%5E%7B-t%20%2A%20n%7D%20%5D%20%2A%20%5B%5Cfrac%7B%281%20%2B%20%5Cfrac%7Br%7D%7Bn%7D%20%29%7D%7B%20%5Cfrac%7Br%7D%7Bn%7D%20%7D%20%5D)
