Answer:
15
Step-by-step explanation:
The price of the bag at the pharmacy is
2/3 * 12 = 8 dollars
You have enough for 10 at the gift shop
10 * 12 = 120
Take 120 dollars and divide by 8 dollars to see how many you can get at the pharmacy
120/8 =15
Monster is a group of cells that have the same function
Answer:
2
Step-by-step explanation:
Given the quadratic equation
3x²+2x-1=0
Let tthe root be α and β
Sum of root α+β = -b/a
Product of root αβ = c/a
Given that;
a = 3, b = 2 and c = -1
α+β = -2/3
αβ = -1/3
To get 1/α + 1/β
Find the LCM
1/α + 1/β
= (α+β)/αβ
= (-2/3)/(-1/3)
= -2/3 * 3/-1
= 2
Hence the required answer is 2
Answer:
Highest area) Student's t-Distribution with 30 degrees of freedom
Middle) Student's t-Distribution with 50 degrees of freedom
Lowest are) Standard deviation distribution
Step-by-step explanation:
Knowing that higher area of the tails correspond to higher dispersion of the t- distribution, and the following properties of t-distribution:
- when the degrees of freedom increase , the dispersion diminishes
- when the degrees of freedom goes to ∞ , t- distribution approaches the standard normal distribution ( thus the z-curve is known as t-curve with df=∞ )
the correct answer is
Tail area : standard deviation < 50 df < 30 df
