A box contains 16 chocolates, of which
3 are known to contain nuts.
Two chocolates are selected at random.
a. Find the probability that
a exactly one chocolate contains
nuts

b at least one chocolate contains
nuts.

Answers

Answer:

3/16??? and 1/16???

Step-by-step explanation:

im so sorry this might be wrong

The probability that a exactly one chocolate contains nuts is 3/16 and probability that at least one chocolate contains nuts is 0.339.

How to calculate probability ?

Probability is calculated by dividing the number of possible outcomes by the total number of possible outcomes. Probability and odds are two distinct concepts. Odds are calculated by dividing the probability of something happening by the probability of it not happening.

When you calculate probability, you are estimating the likelihood of something occurring and representing it with a precise number.

The probability that a exactly one chocolate contains nuts

No of total chocolates = 16 chocolates

No of chocolates contain nuts = 3

The probability that a exactly one chocolate contains nuts = 3/16

Probability that  at least one chocolate contains nuts is

P(at least one contains nut) = 1 – P(given contains no nuts )^n

P(at least one contains nut) = 1 – (0.8125)^2

P(at least one contains nut) = 0.339

Probability that  at least one chocolate contains nuts = 0.339

Find the area of the following polygon:

Answers

Answer:

split it into two shapes

Step-by-step explanation:

you will get a rectangle and triangle, evaluate areas.

Answer:

84m

Step-by-step explanation:

First split the shape up. There can be rectangle and then a triangle at the top.

Find the area of the rectangle first:

12 * 4 = 48.

Rectangle area 48m

Now find the area of the triangle at the top:

The base of the triangle is 12. The height would be 10-4 which gives you the height of 6.  So, 12 * 6 divided by 2 would give you the area of the triangle.

12 * 6 = 72, 72/2 = 36

Triangle Area 36m

Now add the two areas up: 48 + 36 = 84

So the area of the polygon is 84m

Answers

vu=15 su=square root 450 TV= square root 450 SW= squareroot 450/2

We want to find the missing measures for the given square.

VU = 15TV = 21.2SU = 21.2SW = 10.6

Working with squares.

We know that squares have the same length in all of their 4 sides, with that in mind we can see that:

TS = TU = UV = SV = 15

Then we can already complete:

VU = 15

Now we need the two diagonals, SU and TV.

The diagonal for a square of side length s is:

diagonal = (√2)s

Then the diagonals for our square are:

TV = SU = (√2)*15 = 21.2

And SW is half of the diagonal, so we have:

SW = 21.2/2 = 10.6

Let f(x) = y

Solve for y.

ln x = ln(2^y)

ln x = y ln 2

ln x/ln 2 = y

Replace y with f^(-1) x.

f^(-1) x = ln x/ln 2

We now know f(x) and f^(-1) x.

Answer:

x = 12

m(QS) = 52°

m(PD) = 152°

Step-by-step explanation:

Recall: Angle formed by two secants outside a circle = ½(the difference of the intercepted arcs)

Thus:

m<R = ½[m(PD) - m(QS)]

50° = ½[(12x + 8) - (4x + 4)] => substitution

Solve for x

Multiply both sides by 2

2*50 = (12x + 8) - (4x + 4)

100 = (12x + 8) - (4x + 4)

100 = 12x + 8 - 4x - 4 (distributive property)

Add like terms

100 = 8x + 4

100 - 4 = 8x

96 = 8x

96/8 = x

12 = x

x = 12

✔️m(QS) = 4x + 4 = 4(12) + 4 = 52°

✔️m(PD) = 12x + 8 = 12(12) + 8 = 152°

X=27?54?61

So, time taken for Caleb to paint the room alone is

Let us assume the same be x

Kevin time taken + caleb time taken = total time taken

[tex]\frac{1}{18} + \frac{1}{x} = \frac{1}{15}\\\\ \frac{1}{x} = \frac{1}{15} - \frac{1}{18}\\\\ \frac{1}{x} = \frac{6-5}{90} \\\\ \frac{1}{x} = \frac{1}{90}[/tex]
