Answer: Option A.
Step-by-step explanation:
The joint probability for two different things is equal to the product of the individual probabilities.
For contractor A we have:
Prob that the job is done in time = 0.95
Prob that the job is done within the budget = 0.97
Prob of both things at the same time P = 0.95*0.97 = 0.92
For company B we have:
Prob that the job is done in time = 0.98
Prob that the job is done within the budget = 0.93
Prob of both things at the same time P = 0.98*0.93 = 0.91
Then the best contractor is contractor A, (with a joint probability of p = 0.92) and the correct option is option A.
Answer:
Improper: 2 42/9 proper: 6 6/9
Step-by-step explanation:
2 7/9 x 2/3
find the common denominator which is 9 so now we have,
2 7/9 x 2/9
find the numerator which is,
2 7/9 x 6/9
multiply
2 42/9
This fraction is improper so lets make it proper,
42 goes into 9 four times
so we have,
6/9 + 2 + 4
final answer,
6 6/9
This question is Incomplete because it lacks the appropriate diagram for the square pyramid. Please kindly find attached the required diagram
Answer:
45 square inches
Step-by-step explanation:
From the question, we are told that the foil covers the body of the trophy including the bottom, hence the formula we would be applying =
Total Surface Area of the Square pyramid = 2bs + b²
Where s = Height of the square pyramid
b = Edge length of the square pyramid
From the attached diagram, we can see that:
s = 6 inches
b = 3 inches
Total Surface Area of the Square pyramid = 2bs + b²
= 2 × 3 × 6 + 3²
= 36 + 9
= 45 square inches.
Therefore, the amount of gold foil it took to cover the trophy, including the bottom is 45 square inches
25÷5=5
if it takes 1 min for 5 gallons of gasoline to be pumped then 25÷5=25
Answer:
-4
Step-by-step explanation:
-10 - (-6)
Remove the brackets:
-10 - - 6
Remember that all negative and negative values are always positive because they are the same; if they are different, for instance, a positive value and a negative value, then that value will be a negative value.
Continue solving:
-10 - - 6
- and - are positive values
- 10 + 6
= - 4
Therefore the answer is 4
