I think the answer is (4) because if you rotate AEC to the left (counterclockwise) and follow by the scale factor of 2 so, CE = 4x2 = 8 and CA = 3x2 = 6. Hope this help :))

Answer:

3060 $cm^{2}$

Step-by-step explanation:

Find the cross-sectional area first of the trapezium

$\frac{1}{2} (a+b)h$

So, $\frac{1}{2}(6+34)15$

which is 40 / 2 x 15 = 20 x 15 = 300 $cm^{2}$

Since there are 2 trapeziums (on the front and back): 300 x 2 = 600 $cm^{2}$

Find the Area of the Rectangles

The first rectangle on the top would be: 6x30 = 180 $cm^{2}$

The slanted rectangle on the right would be: 25x30 = 750 $cm^{2}$

The rectangle on the bottom would be: 30x34 = 1020 $cm^{2}$

The hidden rectangle on the left would be: 17 x 30 = 510 $cm^{2}$

So by combining all these calculations, you will get the total surface area which is:

600 + 180 + 750 + 1020 + 510 = 780 + 1770 + 510 = 2550 + 510 = 3060 $cm^{2}$

Samples of rejuvenated mitochondria are mutated (defective) in 3% of cases. Suppose 17 samples are studied, and they can be cons

andrey2020 [161]

Answer:

a) 59.58%

b) 90.90%

c) 0%

Step-by-step explanation:

Let p be the probability a sample is mutated. Then q= 1-p is the probability the sample IS NOT mutated.

So p=0.03 (3%) and q=0.97 (97%).

The experiment of finding a mutated sample out of 17 clearly has a binomial distribution, where the probability of finding k mutated samples out of 17 is given by

$P(17;k)=\binom{17}{k}(0.03)^k(0.97)^{17-k}$
