I think the length of CA would be 5 because DE is 5 and they are vertical angles that share a vertex so they must be congruent. I would then use the SAS method.

What is the final amount of 777 is decreased by 12% followed by a 4% increase? Give your answer rounded to 2dp.
julia-pushkina [17]

Answer:

711.11

Step-by-step explanation:

<h3>Method 1 </h3>

If 777  is decreased by 12%. the number would now be (100% - 12%) 88% of what it was originally

0.88 x 777 = 683.76

683.76 is increased by 4%.  683.76 would now be (100 + 4%) 104% of what it originally was

683.76 x 1.04 = 711.11

<h3>Method 2 </h3>

12% x 777 =

0.12 x 777 = 93.24

777 - 93.24 = 683.76

4% x 683.76 = 27.3504

683.76 + 27.3504 = 711.11

Suppose that an experiment is repeated four times. A certain event has probability 1/10 in a single repetition of the experiment
Mazyrski [523]
Best thing you can do in order to answer all of this is to use the <span>Bernoulli trials. You can look for it and see if the answers I'm giving you are correct:
</span><span>Probability of occurring 4 times = (1/10)^4
Probability of never occurring = (9/10)^4
Probability that it occurs at least once = 1 - (9/10)^4
Probability that it occurs in the fourth trial only = (9/10)^3 * 1/10
</span>I think this is going to be very helpful
