Glenda checks the computer monitors made at her company for defects. It has been shown that 0.5% of the monitors are defective.

She decides to check several monitors and record if they are defective. Which of the following will make this process into a binomial experiment?

The statement that will make this process into a binomial experiment is that "C. Glenda checks the monitors until she has 300 non-defective monitors."

Here are the following choices:
<span>A. Glenda checks the monitors until she has 300 defective monitors.
B. Glenda checks 300 monitors and records the number that are defective.
C. Glenda checks the monitors until she has 300 non-defective monitors.
D. Glenda chooses to check 300 monitors.</span>

What is the equation of a line (in standard form) that passes through point A(1,-4) and has a slope of 3/4?
Anna35 [415]

Answer:

3x-4y=19

Step-by-step explanation:

Hi there!

We want to write the equation of the line in standard form that passes through the point (1, -4) and has the slope of 3/4

Standard form is written as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0, and a cannot be negative

First, in order to find ax+by=c, we'll need to get slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept

Since we already know the slope (3/4), we can substitute it into the formula for y=mx+b.

y=3/4x+b

Now we need to solve for b

Since the equation passes through the point (1, -4), we can use it to solve for b

Substitute 1 as x and -4 as y.

-4=3/4(1)+b

Multiply

-4=3/4+b

Subtract 3/4 from both sides

-19/4=b

Now substitute -19/4 as b into the equation

y=3/4x-19/4

Now we have the equation in slope-intercept form, but remember, we want it in standard form

Since x and y are on the same side in standard form, subtract 3/4x from both sides

-3/4x+y=-19/4

Remember that a cannot be negative, and the coefficients are integers (they cannot be fractions)

So in order to clear the fractions and change the sign of the equation, multiply both sides by -4

-4(-3/4x+y)=-4(-19/4)

Multiply

3x-4y=19

Hope this helps!

What is the probability of rolling a three on the first die and a two on the second die?
Neporo4naja [7]
The two rolls of the number cube are independent events because
the result of 1 roll does not affect the result of the other roll.
To find the probability of two independent events, we first find
the probability of each event, then we multiply the probabilities.
We can find the probability of an event using the following ratio:
number of favorable outcomes/total number of outcomes
Since there is only one way to roll a 3 and there are six
possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.
Since there is also only one way to roll a 2 and there are
six possible outcomes, the probability of rolling a 2 would be 1/6.
Now we multiply the probabilities.
1/6 x 1/6 is 1/36.
So the probability of rolling a 3 and a 2 is 1/36.

The variable Z is directly proportional to X. When X is 3, Z has the value 57. What is the value of Z when X = 8
Olin [163]
When x = 3 z = 57 57/3 = 19
19*8 = 152
So when X is equal to 8, Z is equal to 152.
