Answer:
(1) 1 and 7
Step-by-step explanation:
Hello!
We can solve by isolating the variable.
<h3>Solve</h3>
- 3(x - 4)² = 27
- (x - 4)² = 9
- √(x - 4)² = √9
- (x - 4) = ± 3
- x = 4 ± 3
There are two solutions, 1 and 7.
The answer is option 1: x = 7, x = 1.
Answer:
$7.52 = 7 dollars and 52 cents.
Step-by-step explanation:
Given that three pounds of coffee = $22.56
1 pound of coffee = $22.56/3
Thus, we would have:
.
A pound of coffee = $7.52
$7.52 = 7 dollars and 52 cents.

Answer:
not statistically significant at ∝ = 0.05
Step-by-step explanation:
Sample size( n ) = 61
Average for student leader graduates to finish degree ( x') = 4.97 years
std = 1.23
Average for student body = 4.56 years
<u>Determine if the difference between the student leaders and the entire student population is statistically significant at alpha</u>
H0( null hypothesis ) : u = 4.56
Ha : u ≠ 4.56
using test statistic
test statistic ; t = ( x' - u ) / std√ n
= ( 4.97 - 4.56 ) / 1.23 √ 61
= 2.60
let ∝ = 0.05 , critical value = -2.60 + 2.60
Hence we wont fail to accept H0
This shows that the difference between the student leaders and the entire student population is not statistically significant at ∝ = 0.05
