Answer:
42n²+21n
Step-by-step explanation:
Answer:
The answers are below
Step-by-step explanation:
1. H0: rho = 0
H1: rho not equal to 0
2. I will add the scatter plot as an attachment
3. ΣX = 523,
ΣY = 1055
ΣX² = 46023
ΣY²= 430407
ΣXY = 111448
n = 7
The correlation coefficient r =
r = 7(111448)-(523)(1055)/√7(46023)-(523)² × √7(430407)-(1055)²
r = 780136-551765/√322161-273529√3012849-1113025
= 228371/220.53*1378.34
= 228371/303965.32
r = 0.751
4. Test statistics
t = r√n-2/√1-r²
= 0.751√5/√0.5640
= 1.679/0.660
= 2.543
5. P value
Degrees of freedom n-2 = 5
T dist(2.543,5,2)
The p value is less than 0.05 so we reject null hypothesis. There is enough evidence to show a linear correlation between budgets and gross receipts.
First find the height of the triangle using the Pythagorean theorem:
Height = √(14^2 - 7^2)
Height = √(196 - 49)
Height = √147
Height = 7 √3
Now find the volume of the cone:
Volume = PI x r^2 x H/3
Volume = 3.14 x 7^2 x 7√3/3
Volume = 621.8177 cubic cm's.
Round the answer as needed.
Answer:
- <u><em>The ratio of the number of flour tortillas to the total number of tortillas is: 6:10, which is equivalent to 3:5.</em></u>
<u><em></em></u>
Explanation:
First, let's make clear that the correct wording is that the ratio of the number of corn tortillas to the number of flour tortillas is 4:6.
From that, you must determine the ratio of the number of flour tortillas to the total number of tortillas.
You can do it with the help of a chart that you can build from the ratio of the number of corn tortillas to to the number of flour tortillas:
# Corn tortillas # Flour tortillas #Total tortillas
4 6 10
Now, the ratio of the number of flour tortillas to the number of total tortillas is:
- Ratio of the numberr of flour tortillas to the total number of tortillas, r:
r = # flour tortillas / # total tortillas = 6:10
That ratio may be simplified by dividing by the greatest common divisor of 6 and 10, which is 2:
