Answer:
0.25
Step-by-step explanation:
Given that:
Number of options per question = 4
Number of correct answer per question = 1
Number of incorrect answers per question = 3
By random guess:
Probability of picking a correct answer :
Number of correct answers / number of options
= 1 / 4 = 0.25
Probability of picking an incorrect answer :
Number of incorrect answers / number of options
= 3/4
Hence,
X :______ 4 _____ - 1
P(X) : ___ 0.25 __ 0.75
Σ(X*P(x))
(4 * 0.25) + (-1 * 0.75)
1 + (-0.75)
1 - 0.75
= 0.25
Answer:
Step-by-step explanation:
The slope intercept form is y = mx + b
Where m is our slope and b is our y-intercept
We're given a slope of 2
We're given a y-intercept of -5
Substituting into y = mx + b gives
ANSWER: Paige's unit rate for filling the bucket, in gallons per minute (gpm) is 1.5
EXPLANATION: Based on the given fractions, we need to divide 3/8 by 1/4. Divide by its reciprocal: 3/8 * 4. Cross out the common factor, 3/2. Then, obtain the result, 1.5 GPM.
