Answer:
10^×1.49+3=0 930574920474
Answer:
a) Probability of two or more questions right is 0.375.
b) Probability of at least one correct answer is 0.8125.
Step-by-step explanation:
Given : A short quiz has two true-false questions and one multiple-choice question with four possible answers. A student guesses at each question. Assuming the choices are all equally likely and the questions are independent of each other, the following is the probability distribution of the number of answers guessed correctly.
X 0 1 2 3
P(X) 0.1875 0.4375 0.3125 0.0625
To find :
a) What is the Probability of two or more questions right?
b) What is the probability of at least one correct answer?
Solution :
a) Probability of two or more questions right is
Probability of two or more questions right is 0.375.
b) Probability of at least one correct answer is
Probability of at least one correct answer is 0.8125.
Step-by-step explanation:
according to the graph on the drawing:
the correct answer is
b. y = -x+2 ; x≤1
y = x+1 ; x>1
Answer:
Step-by-step explanation:

The balance in the account is $3,920.14
<h3>Compound interest</h3>
The formula for calculating the compound interest is expressed as
A = P(1 + r)^t
Given
- P = $3,200.00
- r = 7% = 0.07
- t = 3 years
Substitute
A = 3200(1+0.07)^3
A = 3,920.14
Hence the balance in the account is $3,920.14
