Answer:
2
Step-by-step explanation:
Find the diagram attached
The Base of the triangle will be equivalent to the the length of the rectangle
Since the base of the triangle is 5units, hence length of the rectangle is 5units
Similarly, the height of the triangle is corresponding to the width of the rectangle
Since the height of the triangle is 2 units, the rectangle will be 2 unts wide. Hence the required answer is 2units
This question is incomplete, the complete question is;
A certain organization reported the following scores for two parts of the scholastic Aptitude test ( SAT)
Evidence-based Reading and writing : 533
Mathematics : 527
Assume the population standard deviation for each part is σ = 100.
What is the probability a sample of 66 test takers will provide a sample mean test score within 10 points of the population mean of 533 on the Evidence-based Reading and Writing part of the test?
Answer: the required probability is 0.582
Step-by-step explanation:
Given that;
Population mean = 533
sample size n = 66
population standard deviation σ = 100
σ of x bar = 100/√66 = 12.3091
Normal distribution with mean 533 and SD of 12.3091
P( 523 <x< 543 )
Z = 10 / 12.3091
Z = 0.8124, -0.8124
P( z < 0 0.8124) - P( z < -0.8124) { from table}
⇒ 0.7910 - 0.2090
= 0.582
Therefore, the required probability is 0.582
Answer:
-2.333
Step-by-step explanation:
-x -5 = -2 (-x) +2
-x-5 = 2x +2
-5-2 = 2x +x
-7 =3x
-7/3=3x/3
-2.333=x
:•x=-2.333
Your answer is A :D Hope It Works !
