About 8% of the population of a large country is math phobic. If two people are randomly selected, what is the probability both are math phobic? What is the probability at least one is math phobic?
Answer:
the chances both are is=.64%
the chances of only one is=15.36%
Step-by-step explanation:
8%=.08
.08x.08= .0064=.64%
1-(1-0.08)×(1-0.08)
1-.92x.92
0.1536=
15.36%
a) The probability both are math-phobic: 0.0064 or 0.64%.
b) The probability that at least one is math-phobic is 0.1536 or 15.36%.
To determine the probability that both selected people are math-phobic, we can use the multiplication rule of probability.
Since the selection is random, the probability that the second person is math-phobic is also 0.08.
To find the probability that both events occur, we multiply the individual probabilities:
Probability of both being math-phobic = 0.08 x 0.08 = 0.0064
Therefore, the probability that both selected people are math-phobic will be 0.0064 or 0.64%.
To find the probability that at least one person is math-phobic, we can use the complement rule of probability.
The probability that the first person is not math-phobic ;
1 - 0.08 = 0.92.
Similarly, the probability that the second person is not math-phobic is also 0.92.
Probability of none being math-phobic = 0.92 x 0.92 = 0.8464
Probability of at least one being math-phobic = 1 - 0.8464 = 0.1536
Therefore, the probability that at least one person is math-phobic is 0.1536 or 15.36%.

Two laboratory technicians are running product quality tests . One technician takes 6 minutes less than the other . What equation would give the amount of time , t , it would take to run the tests if the technicians work together to split the work on the different tests ? 1/(6t) = 1/x - 1/(x - 6) B 1/t = 1/x + 1/(x - 6) Oct t = x + x - 6 1/t = 1/x - 1/(x - 6)
Answer:
C. t = x + x - 6Step-by-step explanation:
Let the time use by other one technician be x
if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)
The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.
First technician = x
Second technician = x-6
Sum of the time taken
t = x+ (x-6)
Hence option C is correct

What value of k makes the equation true?
k – 3(k + 5) – 0.5 = 3(0.25k + 4)
Answer:
k = - 10
Step-by-step explanation:
k - 3(k + 5) - 0.5 = 3(0.25k + 4) ← distribute parenthesis on both sides
k - 3k - 15 - 0.5 = 0.75k + 12
- 2k - 15.5 = 0.75k + 12 ( subtract 0.75k from both sides )
- 2.75k - 15.5 = 12 ( add 15.5 to both sides )
- 2.75k = 27.5 ( divide both sides by - 2.75 )
k = - 10

Write an expression for the
product of 4 and m.
Answer:
4m
Step-by-step explanation:
Expressions do not have equal signs, So for the product of 2 things we just multiply them together.
4m
Answer:
4 × M = P
Explanation:
A product is the result of a multiplication expression, so in this case, We're using variables to represent numbers.
P = Product
We're multiplying 4 and M, so lets rewrite this.
4 × M
This is an incomplete expression, but what will we use for our product We can use a variable. Our variable is P. So lets complete this expression.
4 × m = p.
Or, we can put it in a less complex way.
4m.
This also is a incomplete expression, but it means 4 × m.

The distance from the Earth to the Moon is about a hundred times the distance from California to New York. What is a reasonable measure for the Earth-Moon distance?
a -4 times 10^-10 meters
b- 4 times -2 meters
c- 4 times 10^2 meters
d- 4 times 10^8 meters
Answer: D!!!!!!!!!!!!!
The required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.
Given that,
The distance from the Earth to the Moon is about a hundred times the distance from California to New York. What is a reasonable measure for the Earth-Moon distance is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Options A, B, and C is reasonable false because all are impossible terms for the distance, earth to the moon.
Option D is reasonably correct because 4 * 10^8 seems larger as the distance from the earth to the moon is also larger.
Thus, the required reasonable measure for the earth-moon distance is 4 times 10^8 meters. Option D is correct.

Step-by-step explanation:
5x + y = 7
-x - 2y = - 15
What we can do is multiply the second equation by 5, as we try to combine both equations to get rid of x.
5x + y = 6
-5x - 10y = 75
-9y = 81
y = -9
Now we plug y back in.
5x - 9 = 6
5x = 15
x = 3
