Answer:
The probability that the student will not guess correctly on any one question is 4/5
Step-by-step explanation:
The question posed is an application of the binomial probability distribution.
We have been informed that the test has multiple choice questions with 5 choices for each answer that only one answer is correct for each question.
If the student guesses the answer to each question, then the probability that the student will guess correctly on any one question is 1/5.
Therefore, the probability that the student will not guess correctly on any one question is;
1 - 1/5 = 4/5
Answer: The test statistic is 1.75.
Step-by-step explanation:
Since we have given that
n = 47
First mean difference = 1
and second mean difference = 1.2
Standard deviation = 0.78
So, the value of test statistic would be
Hence, the test statistic is 1.75.
U can divide the whole equation by 3, u get: x^2+12x+27
Find factors of 27 that add up to 12; we get 9 and 3
So the answer is (x+3)(x+9); answer is B
Hello!
Since the shape has 6 points it is a hexagon
The sum of the angles in a hexagon add to 720
You add all the angles you know
102 + 133 + 117 + 170 + 90 = 612
Subtract this from 720 to find b
720 - 612 = 108
The answer is B) 108°
Hope this helps!
Answer: 19.42
Step-by-step explanation:
To find the distance, we need to use the distance formula.
With the given points, we can plug them in and solve.
[parenthesis]
[exponent]
[add]
[square root]
Now, we know the distance is 19.42.
