Answer:
c. One sided t-test
Step-by-step explanation:
One sided t test because we want to compare two means and alternative hypothesis is directional.
Given:
total cost : 28.70
cost per pint of fruit : 2.85
Formula:
5v + 7f = 28.70
5v + 7(2.85) = 28.70
5v + 19.95 = 28.70
5v = 28.70 - 19.95
5v = 8.75
5v/5 = 8.75/5
v = 1.75 cost per pint of veggies.
to check:
v = 1.75 ; f = 2.85 ; total cost = 28.70
5v + 7f = 28.70
5(1.75) + 7(2.85) = 28.70
8.75 + 19.95 = 28.70
28.70 = 28.70
0.185 is your decimal answer but your fraction answer is 37/200 according to my spidey senses.
A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. I dont know about the other question
Answer:
Assume that 1900km^2 is 1900.
If that happens, The equation of that will look like...
1900 - (1900 x 7.75% x 14)%.
1900 x 7.75% are 147.25.
and 147.25 x 14 are 2061.5.
so... there will be no forest after 14 years.(harsh)
Hope it helps!
