Answer:

0.17

Step-by-step explanation:

The number of times there is free Breakfast at work = 25%

The number of times the coworker lies = 1/3

The number of times the coworker speaks truth = 2/3

How likely is it that there is free breakfast at work today:

For this to happen both conditions must be satisfied. There must be free breakfast at work AND the coworker has also spoken truth. Now in this condition we will use the AND rule of Probability where we will take the Product of both the probabilities.

Result = 0.25 x 0.67 = 0.17

Answer:

\frac{1}{6}

Step-by-step explanation:

Data provided in the question:

Probability of free breakfast = 25% = 0.25

P( coworker lies | free breakfast ) = \frac{1}{3}

Therefore,

P(Coworker did not lie | Free Breakfast)

= 1 -  P( coworker lies | free breakfast )

= 1 -  \frac{1}{3}

=  \frac{2}{3}

Now,

P(Free breakfast at work | coworker told there is free breakfast)

=  P(Coworker did not lie | Free Breakfast) × P(Free breakfast)

= \frac{2}{3} × 0.25

= \frac{1}{6}

What is the sum of the arithmetic sequence 3, 9, 15…, If there are 34 terms?
snow_tiger [21]

Answer:

first we find the common difference.....do this by subtracting the first term from the second term. (9 - 3 = 6)...so basically, ur adding 6 to every number to find the next number.

we will be using 2 formulas....first, we need to find the 34th term (because we need this term for the sum formula)

an = a1 + (n-1) * d

n = the term we want to find = 34

a1 = first term = 3

d = common difference = 6

now we sub

a34 = 3 + (34-1) * 6

a34 = 3 + (33 * 6)

a34 = 3 + 198

a34 = 201

now we use the sum formula

Sn = (n (a1 + an)) / 2

S34 = (34(3 + 201))/2

s34 = (34(204)) / 2

s34 = 6936/2

s34 = 3468 <=== the sum of the first 34 terms:

Can anyone help me in this whole math question? Especially Number b and c. <br>Thanks. ​
Bogdan [553]

Answer:

Irregular polygons are polygons that do not have equal sides or equal angles. When finding the area of an irregular polygon, partition the polygon into smaller regular polygon shapes. You can then plug those measurements into their respective area formulas and multiply to find the area of one part of the shape.

This is 16cm.

This is basically a simple problem to understand. The only thing that needs to be done is to divide the mass of the sun by the mass of mercury. It will give the required result.
