Answer:
44 and 110
Step-by-step explanation:
The ratio of the 2 numbers = 2 : 5 = 2x : 5x ( x is a multiplier ) , thus
difference = 5x - 2x = 3x , then
3x = 66 ( divide both sides by 3 )
x = 22
Thus
2x = 2 × 22 = 44
5x = 5 × 22 = 110
The 2 numbers are 44 and 110
Answer:
$10,603.20
Step-by-step explanation:
You can calculate the simple interest of the loan using the formula:
I = prt, where I = interest, p = principal amount, r = interest rate and t = time. Plugging in the values from the problem:
p = $7,050
r = 8.4% or 0.084
t = 6 years
I = (7050)(0.84)(6) = $3,553.20
To find the total cost of the boat, add the interest and the purchase price:
$7,525 + $3,553.20 = $11,078.20
Answer:
t = 2.2450
d. 0.264
Step-by-step explanation:
The null hypothesis is:
Alternative hypothesis;
The pooled variance t-Test would have been determined if the population variance are the same.
The t-test statistics can be computed as:
t = 2.2450
Degree of freedom 
df = (8-1)+(8-1)
df = 7 + 7
df = 14
At df = 14 and ∝ = 0.05;
Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.
Conclusion: We reject 
and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.
To calculate r²
The percentage of the variance is;
Answer:
C) 1
F) 29
Step-by-step explanation:
all numbers less than 30 are solutions
