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.
X - 0.38x = 868......x is the same as 1x
1x - 0.38x = 868
0.62x = 868...now divide both sides by 0.62
x = 868 / 0.62
x = 1400 <==
99% = 99 / 100 = 0.99
79.9 is 99% of what
= 79.9 / 99
=79.9 / 0.99

The cost of 1 bag of almond is $1.25
What is linear equation?
An equation in which the highest power of the variable is one is known as linear equation.
We can find the cost of 1 bag of almond as shown below:
Let the cost of 1 bag of peanut be $x
Let the cost of 1 bag of cashews be $y
Let the cost of 1 bag of almonds be $z
x + y + z=3 (1)
2x+2y=3.50
Dividing by 2
x + y=1.75
Putting in equation (1)
1.75+z=3
z=3-1.75
z=1.25
Hence, the cost of 1 bag of almond is $1.25
