Answer:
The value of the test statistic 
Step-by-step explanation:
From the question we are told that
The high dropout rate is
% 
The sample size is 
The number of dropouts 
The probability of having a dropout in 1000 people 
Now setting up Test Hypothesis
Null 
Alternative
The Test statistics is mathematically represented as

substituting values


Answer and Explanation:
Brielle will run the marathon faster.
Work:
Brielle: 13.1/1.25=10.48*10=104.8 minutes
Joshua: 13.1/1.5=8.73...*18=157.2 minutes
Brielle finished in 104.8 minutes.
Joshua finished in 157.2 minutes.
Brielle finished the half marathon race by 52.5 minutes faster than Joshua.
Hope this helps!!! PLZ MARK BRAINLIEST!!!
Answer:420
Step-by-step explanation x=90/0.375
Answer:
(x + 5)^2 + (y + 8)^2 = 6^2
Step-by-step explanation:
A circle formula: (x - h)^2 + (y - k)^2 = r^2
We are given diameter. To find the radius divide diameter by 2.
d = 12
12/2 = r = 6
H and K are given to be (-5 , -8)
(x - (-5))^2 + (y - (-8))^2 = 6^2
(x + 5)^2 + (y + 8)^2 = 6^2
I have plot this equation to confirm my answer is correct where the origin is (-5 , -8) and has a radius of 6.
Answer:
- domain: all terms are defined for <em>all real numbers</em>
- solution: x = 6
Step-by-step explanation:
Rewrite the equation as a single exponential. After taking the log, the solution becomes obvious.
