A trapezoid is a quadrilateral that has two parallel sides with a height.

From the diagram, AK = 1/2(AD-BC)

The combination of the bases of the equilateral triangle and the parallelogram is = the base of the trapezoid.

Therefore, BC = AD - 2AK

Make AK the subject of formula,

AK= 1/2 (AD -BC)

KD = 1/2(AD - BC). This is wrong because of the following,

BC is parallel to KD.

Therefore length of KD = BC - AK and not KD = 1/2(AD - BC).

Step-by-step explanation:

We need indirectly m<POQ

See NR is a straight line so the three angles situated underneath are linear pair and supplementary

m<POQ

Answer:

C)  35°

Step-by-step explanation:

From inspection of the given diagram, it appears that the line segment NOR is the diameter of the circle (where point O is the center).

Angles on a straight line sum to 180°

⇒ ∠NOP + ∠POQ + ∠QOR = 180°

⇒ 82° + ∠POQ + 63° = 180°

⇒ ∠POQ = 180° - 82° - 63°

⇒ ∠POQ = 35°

As an arc measure equals its corresponding central angle measure:

2*2=4

9+4=13

36-13=23 shaded area

Answer:

1 - 4/9

2 - 1/9

3 - 5/9

Step-by-step explanation:

1 - Look on the left side for all two-letter combinations with only one R. We can see four. (YR, GR, RG, RY). Divide by the total number of outcomes (9).

2 - There is only one with two yellows, so divide 1 by 9.

3 - Same as before, we find 4 with 1 green and 1 with 2 green. We have to include the new one since it says atleast one. Add 1 and 4 and then divide by 9.

Step-by-step explanation:

the probability of making one shot is 75% or 0.75 or 3/4.

the probability to make 2 shots is then

3/4 × 3/4 = 9/16 = 0.5625

and so on.

the probability to miss 1 shot is then 25% or 0.25 or 1/4.

the probability to make at least 4 out of 5 shots is the sum of the probability to make all 5 shots plus the probability to make 4 shots.

or the probability to miss 0 plus the probability to miss 1 shot.

anyway, we can go with the positive approach. it seems to be the same complexity as the negative approach.

the probability to make all 5 shots is

(3/4)⁵ = 3⁵/4⁵ = 243 / 1024 = 0.237304688...

the probability to e.g make the first 4 shots and miss the 5th is

(3/4)⁴×1/4 = 3⁴/4⁵ = 81 / 1024 = 0.079101563...

how many possibilities do we have to make 4 out of 5 shots ?

there is no repetition, and the sequence inside the "picked" 4 does not matter, so we need combinations :

C(5,4) = 5! / (4! × (5-4)!) = 5

so, the probability to make exactly 4 out 5 shots is

81/1024 × 5 = 405/1024 = 0.395507813...

and the total probability to make at least 4 shots is

243/1024 + 405/1024 = 648/1024 = 81/128 = 0.6328125

to control,

this plus making exactly 3 plus exactly 2 plus exactly 1 plus none must be the probability 1 (as there is no other possible outcome).

making 3 :

(3/4)³×(1/4)² = 3³/4⁵ = 27/1024

C(5,3) = 5×2 = 10

270/1024

making 2 :

3²/4⁵ = 9/1024

C(5,2) = 5×2 = 10

90/1024

making 1 :

3/1024

C(5,1) = 5

15/1024

making 0 :

1/1024

in sum

(270+90+15+1)/1024 = 376/1024

plus the 648/1024 = 1024/1024 = 1

correct.

1³ + 2³ + 3³

Answer:

The population after 516 minutes is 171360 bacteria

From the question, we have the following parameters that can be used in our computation:

Initial, a = 10,710 bacteria

Rate = doubles i.e. 2

Using the above as a guide, we have the following:

f(x) = a(2)^x

Where x is the time

516 minutes is 4 times 129 minutes

This means that

x = 516/129 = 4

So the population after 516 minutes can be calculated as follows:

f(4) = 10710 * (2)^4

Evaluate

f(4) = 171360

Hence, the population is 171360
