Answer:
Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
Since the area of a square is equal to the square of one of its side's length, then the area should be equivalent to
.
---> equation (1)
By using pythagoras rule which states that the
---> equation (2)
where the opposite side's length is 8 and the hypotenuse side's length is 10
by substituting by the values in equation (2) therefore,
substitute this value in equation (1) then
where A is the area of the square whose side is x
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
What you must do in this case is to use the potential type function given in the problem:
a (b) ^ x = c
We have:
new car for $ 17,930
a = 17930
The value of the car depreciated by 19% per year
b = 1-0.19 = 0.81
the car is worth no more than $ 1,900
c = 1900
the exponential inequality is:
a (b) ^ x ≤ c
17930 (0.81) ^ x ≤ 1900
Answer:
the exponential inequality is:
17930 (0.81) ^ x ≤ 1900
where
x: number of years
