Answer:

The likelihood that both tests will identify the bacteria is  83.66%....

Step-by-step explanation:

The first test has a 94% accuracy rate = 0.94

The second test displays a 89% accuracy rate = 0.89

The probability that both tests identify the bacteria is computed by multiplying the two probabilities:

= 0.94*0.89

= 0.8366

When this value is converted to a percentage, we arrive at

0.8366*100

= 83.66%

This means the probability that both tests will detect the bacteria is  83.66%....

Jenny multiplies the square root of her favorite positive integer by $\sqrt{2}$. Her product is an integer. a) Name three number
tester [12383]

Answer:Part a) 2,50,18

Part b) When Jenny divides the square root of her favorite positive integer by \sqrt{2}, the result is an integer.

Step-by-step explanation:

Let

x-------> the favorite positive integer

Part a)

1) For x=2

\sqrt{2}*\sqrt{2}=\sqrt{4}=2 -----> the product results in an integer

thus

The number x=2could potentially be Jenny's favorite positive integer

2) For x=50

\sqrt{50}*\sqrt{2}=\sqrt{100}=10 -----> the product results in an integer

thus

The number x=50could potentially be Jenny's favorite positive integer

3) For x=18

\sqrt{18}*\sqrt{2}=\sqrt{36}=6 -----> the product results in an integer

thus

The number x=18could potentially be Jenny's favorite positive integer

Part B)

1) For x=2

\sqrt{2}/\sqrt{2}=\sqrt{1}=1 -----> the outcome is an integer

2) For x=50

\sqrt{50}/\sqrt{2}=\sqrt{25}=5 -----> the outcome is an integer

3) For x=18

\sqrt{18}/\sqrt{2}=\sqrt{9}=3 -----> the outcome is an integer

Therefore

When Jenny divides the square root of her favorite positive integer by \sqrt{2}, she obtains an integer as a result.

Zina [12379]
To tackle this problem, you can use the same method from the prior situation.

Option 1: 2/(1/16 + 1/65) = 25.7 mpg

Option 2: 2/(1/14 + 1/85) = 24.0 mpg

_____
Like before, enhancing the least efficient vehicle yields the best outcome.

Mari has a part time job. She earns $7 an hour. She makes at most $143.50 a week. What is the greatest number of hours that she
Zina [12379]
<span>To find out how much she makes weekly, we must multiply her hourly wage of $7 by the total hours she worked throughout the week. When determining how many hours she worked, we need to rearrange the formula: Salary per week = hourly wage x hours worked In this case, we already know two pieces of information: hourly wage and total weekly salary. Hours worked = weekly salary / hourly wage Hours worked = 143.50 / 7 Hours worked = 20.5 Therefore, the maximum hours she can work is 20h30.</span>
