12 A quality control inspector at a plant has found the probability of randomly selecting a defective
battery from a batch of batteries being produced is 0.02. The probability of rain that day has been
projected to be 0.75. If these two events are independent, what is the probability that on that particular
day, it rains, and the inspector chooses a defective battery from the batch being produced?
(1) 0.77
(3) 0.015
(2) 0.5
(4) 0.95
Answer:
The answer is (3) 0.015.
Step-by-step explanation:
This is because to find the probability of finding both independent events happening at the same time, we must multiply them.
The independent events are:
- Randomly selecting a defective battery: 0.02
- Raining tomorrow: 0.75
0.02 x 0.75 = 0.015
Therefore, the answer is (3) 0.015.
find the statement that is incorrect. Then, correct and rewrite the statement in the space provided. Show any necessary work.
The incorrect statement is b. When an aeroplane takes off, the work done by its weight is negative.
The inaccurate assertion is:
b) When a plane removes, the work done by its weight is positive.
The right assertion is:
b) When a plane removes, the work done by its weight is negative.
Clarification:
At the point when a plane removes, the work done by the heaviness of the plane is negative in light of the fact that the weight acts the other way to the dislodging of the plane. As indicated by the work-energy hypothesis, work done by the heaviness of the plane will diminish its motor energy, and that implies that the work done is negative. Hence, articulation (b) is inaccurate.
a) Work and energy have various units.
This assertion is right. Work has units of Joules (J) and energy additionally has units of Joules (J), however they are not exactly the same thing.
c) The possible energy of spring increments when it is broadened and diminishes when it is packed.
This assertion is right. The potential energy put away in a spring is straightforwardly corresponding to its expansion or pressure. While a spring is broadened, its potential energy increments, and when it is packed, its potential energy diminishes.
d) On the off chance that the work done by outside powers on a framework is negative, the energy of the framework diminishes.
This assertion is right. On the off chance that the work done by outside powers on a framework is negative, the energy of the framework diminishes.
The work-energy hypothesis expresses that the net work done on a framework is equivalent to the adjustment of its motor energy, and in the event that the net work is negative, the dynamic energy diminishes, and that implies that the energy of the framework diminishes.
e) When a body is falling unreservedly from a level, its dynamic energy stays consistent.
This assertion is erroneous. At the point when a body is falling unreservedly from a level, its potential energy is changed over into dynamic energy as it falls. Hence, its motor energy increments as it falls, and its potential energy diminishes.
f) The unit of force is watt.
This assertion is right. The unit of force is watt (W), which is characterized as the pace of taking care of business or the pace of move of energy.

Using trigonometric identities when cosθ = √2/2 and 3π/2 < θ < 2π
sinθ = -√2/2 tanθ = - 1What are trigonometric identities?Trigonometric identities are mathematical equations that contain tigonometric ratios
Since cosθ = √2/2 and 3π/2 < θ < 2π, we desire to find sinθ and tanθ. We proceed as follows
a. To find sinθ, using the trigonometric identity
sin²θ = 1 - cos²θ
⇒ sinθ = ±√(1 - cos²θ)
So, substituting the value of cosθ into the equation, we have that
sinθ = ±√(1 - cos²θ)
sinθ = ±√(1 - (√2/2)²)
= ±√(1 - 2/4)
= ±√[(4 - 2)/4]
= ±√[2/4]
= ±√2/2
Since 3π/2 < θ < 2π, which is the fourth quadrant, we take the negative answer.
So, sinθ = -√2/2
b. To find tannθ, using the trigonometric identity
tan²θ = sec²θ - 1
⇒ tanθ = ±√(sec²θ - 1)
= ±√(1/cos²θ - 1)
So, substituting the value of cosθ into the equation, we have that
tanθ = ±√(1/cos²θ - 1)
tannθ = ±√(1/(√2/2)² - 1)
= ±√(1/2/4 - 1)
= ±√(4/2 - 1)
= ±√[2 - 1]
= ±√1
Since 3π/2 < θ < 2π, which is the fourth quadrant, we take the negative answer.
So, tanθ = -1

Write the following Babylonian numeral as a Hindu-Arabic numeral.
<|| <<||||
Answer:
The Babylonian numeral <|| <<|||| represents the number 51 in the Babylonian numeral system.
To convert it to the Hindu-Arabic numeral system, we first need to determine the place values of the symbols. The symbol <|| represents 50 and <<|||| represents 1.
So, we can write the number as:
50 + 1 = 51
Therefore, the Hindu-Arabic numeral equivalent of the Babylonian numeral <|| <<|||| is 51.
A culture started with 3,000 bacteria. After 4 hours, it grew to 3,600 bacteria. Predict how many bacteria will be present after 10 hours.
Round your answer to the nearest whole number.
P = Aekt
Answer:
Step-by-step explanation:
To predict the number of bacteria after 10 hours using the formula P = Aekt, where P is the final population, A is the initial population, k is the growth rate, and t is the time elapsed, we need to first find the value of k.
dw
We know that after 4 hours, the population grew from 3,000 bacteria to 3,600 bacteria. So we can set up an equation:
3,600 = 3,000e^(4k)
Dividing both sides by 3,000 gives:
1.2 = e^(4k)
Taking the natural logarithm of both sides gives:
ln(1.2) = 4k
Solving for k, we get:
k = ln(1.2)/4
k ≈ 0.051
Now that we have the value of k, we can use the formula to predict the number of bacteria after 10 hours:
P = 3,000e^(0.051*10)
P ≈ 5,426
Therefore, we predict that after 10 hours, there will be approximately 5,426 bacteria present in the culture.

A local store was offering a discount of 25% on original parice on older model laptops. Gina bought an older model laptop for $963 that includes a 7% tax on the discounted price
Answer:
Step-by-step explanation:To solve this problem, we need to work backwards from the final price that Gina paid and determine the discounted price before tax was added.
Let x be the original price of the laptop. After a 25% discount, the discounted price is:
Discounted price = x - 0.25x = 0.75x
Next, we add 7% tax to the discounted price:
Final price = (0.75x) + 0.07(0.75x) = 0.8025x
We know that the final price that Gina paid was $963, so we can set up an equation:
0.8025x = 963
Solving for x, we get:
x = 1200
Therefore, the original price of the laptop was $1200, and the discounted price before tax was:
Discounted price = 0.75x = 0.75(1200) = $900
To check, we can add the 7% tax to the discounted price:
Final price = $900 + 0.07($900) = $963
This matches the price that Gina paid, so we can be confident in our answer.

A printer is printing photos. For every 6 photos, the printer takes 3 minutes.
Complete the table below showing the number of photos and the time it takes to print them.
We can start by finding the rate at which the printer is printing photos. Since it takes 3 minutes to print 6 photos, we can calculate the rate as 6 photos / 3 minutes = 2 photos/minute. This means that for every minute that passes, the printer prints 2 photos.
Now that we know the rate, we can use it to find out how long it will take to print 16 photos. Since the rate is 2 photos/minute, we can set up an equation to solve for y (time) when x (photos) is 16: 2 = 16/y. Solving for y, we get y = 16/2 = 8.
Therefore, when x (photos) is 16, y (time) is 8 minutes. This means that it will take the printer 8 minutes to print 16 photos.
If y (time) is 5 minutes, we can use the rate we calculated earlier to find out how many photos the printer will print in that time. Since the rate is 2 photos/minute, we can multiply it by the time to find out how many photos will be printed: 2 photos/minute * 5 minutes = 10 photos.
Therefore, if y (time) is 5 minutes, the printer will print 10 photos.
If y (time) is 7 minutes, we can use the rate we calculated earlier to find out how many photos the printer will print in that time. Since the rate is 2 photos/minute, we can multiply it by the time to find out how many photos will be printed: 2 photos/minute * 7 minutes = 14 photos.
Therefore, if y (time) is 7 minutes, the printer will print 14 photos.

Correlation could be positive or negative
Correlation and y-intercept have the same sign
The True statements about the correlation are: (1), (2), (3), (5), (6) and (7)
1) We know that the adding, subtracting, multiplying or dividing a constant to all of the data points in one or both variables does not change the correlation coefficient.
So, the first statement is True.
2) We know that the correlation measures the strength of the pattern around a line of regression as well as the direction of the line. So, interchanging the variables would not change the correlation. The correlation between x and y is the same as the correlation between y and x.
Thus the second statement is True.
3) We know that the correlation coefficient does not have any units.
It is just a number between -1 to +1.
Thus the third statement is True.
4) We know that the outlier may weaken the correlation. It makes the data more scattered. So the correlation coefficient r gets closer to 0.

5) We know that if the correlation coefficient r is close to 1 then it is a strong positive correlation and if r is close to -1 then it is a strong negative correlation.
Thus the fifth statement is True.
6) We know that the corrletaion coefficient values can range from -1 to 1.
Thus the sixth statement is True.
7) We know that the y-intercept is nothing but the point at which the regression line intercepts the y-axis. The y-intercept of the regression line and the correlation coefficient have the same sign.
