A triangular-shaped deck has one side that is 4 feet longer than the shortest side and a third side that is 4 feet shorter than

Inessa05 [86]

Answer:

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

Step-by-step explanation:

Assuming that the shortest side of this triangle has a length of "x" feet, then one side is "x + 4" feet and the third is "2*x - 4" feet. Since the perimeter of the deck is 80 feet, then the sum of the length of these sides should be equal to that.

$x + x + 4 + 2*x - 4 = 80\\4*x = 80\\x = \frac{80}{4} = 20 \text{ feet}\\$

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

A local grocery store tested spinach samples for E coli bacteria using two different tests. The first test has a 94% probability

Readme [11.4K]

Answer:

The probability that both tests detect the bacteria is 83.66% ....

Step-by-step explanation:

First test has a probability of giving accurate results = 94% = 0.94

Second test has a probability of giving accurate results = 89% = 0.89

The probability that both tests detect the bacteria is:

Multiply both the probabilities:

=0.94*0.89

= 0.8366

Converting the value into percentage, we get

0.8366*100

= 83.66%

Thus the probability that both tests detect the bacteria is 83.66% ....
