First you have to do 3/5 times 2/2 and 1/2 times 2/2 because you have to find there common denominator. Then you add up the numerators. But make sure you don't add up the denominators. Hope this helped. And please mark me the brainiest.
Answer:
7 marigolds will fit in this row
Step-by-step explanation:
Given
Length of the row for planting marigold = 2 yards
Spacing between the flowers = 1/3 yard
The first marigold is planted at 0 yard, the total number of marigold that can be planted is equal to
A 1/3 B 1/3 C 1/3 D 1/3 E 1/3 F 1/3 G
The alphabets represents the marigold flower
Hence, total 7 flowers can be planted
Answer:
The Population Density is
.
Step-by-step explanation:
Given,
Total number of People = 900,000
Total Land Area = 1800 sq. mi.
Solution,
For calculating the population density, we have to divide the total number of people by the area of the land.
This can be framed in equation form'

Now putting the given values, we get;

Hence The Population Density is
.
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
