mote1985 [20]

Answer:

x=16-2y

Step-by-step explanation:

\mathrm{Subtract\:}\frac{1}{4}y\mathrm{\:from\:both\:sides}

\frac{1}{8}x+\frac{1}{4}y-\frac{1}{4}y=2-\frac{1}{4}y

\mathrm{Simplify}

\frac{1}{8}x=2-\frac{1}{4}y

\mathrm{Multiply\:both\:sides\:by\:}8

8\cdot \frac{1}{8}x=8\cdot \:2-8\cdot \frac{1}{4}y

\mathrm{Simplify}

x=16-2y

Final Answer: x=16-2y

Not really sure whats up with that inequality but she can't, if she has to spend 1.5 hours in a lab that leaves her with 5 hours.  5/4 is 1.25, so no, she can only spend 1.25 hours with each student.

The probability that a car has a certain factory defect is 825. The probability that a car has a certain factory defect and need
ipn [44]

Answer:

90.91% probability that a car needs an oil change given that it has a certain factory defect

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

In this problem, we have that:

Event A: having a factory defect.

Event B: needing an oil change.

The probability that a car has a certain factory defect is 825.

So P(A) = 0.825

The probability that a car has a certain factory defect and needs an oil change is 750.

So P(A \cap B) = 0.75

What is the probability that a car needs an oil change given that it has a certain factory defect

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.75}{0.825} = 0.9091

90.91% probability that a car needs an oil change given that it has a certain factory defect

A company's profit in the first half of the year is $150,000 more than the second half of the year. If the total profit for the
natta225 [31]

Answer:

Profit for First half of the year is $450,000.

Step-by-step explanation:

Let the profit for second half of year be x

Now Given:

Profit in the first half of the year is $150,000 more than the second half of the year.

Profit in first half = \$150,000+x

Total profit for the year = $850,000

We know that Total profit for the year is sum of Profit in first half and Profit in second half

150000+x+x=850000\\150000+2x=850000\\2x= 850000-150000\\2x = 600000\\\\x=\frac{600000}{2}=300000

Profit for Second half of year = $300000

Profit for First half of the year = 150000+x = 150000+300000=\$450,000

Hence Profit for First half of the year is $450,000.
