a local grocery store tested spinach samples for e coli bacteria using two different tests. the first test has a 94% probability of giving accurate results, while the second test is accurate 89% of the time. a sample that contains e coli bacteria is tested.
the probability that both tests detect the bacteria is
%.

Probability of  the first test giving accurate results = 84%

Probability of the second test is accurate = 89%

Answer = 83.66%

Step-by-step explanation:

Got it right on edmentum

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
