Answer:

65°

Step-by-step explanation:

The missing angle of the left hand side triangle is

180 - 78 - 38 =

180 - 116 = 64°

The bottom left angle of the right hand side triangle is

180 - 64 - 61 =

180 - 125 = 55°

The top angle of the right hand side triangle is 60°, by vertical angle theorem.

The missing angle is:

180° - 55° - 60°=

180° - 115° = 65°

If my answer is incorrect, pls correct me!

Answer:

65°

Step-by-step explanation:

First find the angle in the triangle by

78+38 =116 then subtract it by 180 gives 64

after add 64 with 61 gives 125 then again subtract it from 180 again which gives you 55

And as you can already see that 60° side at the top is same with the inner angle, so from there you

55° + 60° = 115°

180°- 115° = 65°

So here's gives that

total weight of 25 bags = 50 x 25

= 1250

total cost of 25 bags weighing 50 kg is = 15000

cost of 1 kg = 15000 ÷ 1250 = 12

now total weight of 15 bags weighing 30 kg = 450

cost per kg = 12

cost of 15 bags weighing 30 each = 450 x 12

Answer = 5400 rupees.

If a=2, b=3 and c=4 then find the numerical value of a2+2abc+b2+c2

qaws [65]

a=2 b=3 and c=4. then,

a2+2abc+b2+c2

a2+2abc+b2+c2= 2^2+2×2×3×4+3^2+4^2

(replace value of a, b, c by2,3,4 respectively tgen solve)

= 4+48+9+16

= 77………………

Therefore, 77 is correct answer.

Records show that the average number of job applications received per week is 5.9. Find the probability of 6 job applications re

german

Answer:

16.05% probability of 6 job applications received in a given week.

Step-by-step explanation:

When you have the mean during an interval, you should use the Poisson distribution.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Records show that the average number of job applications received per week is 5.9.

This means that $\mu = 5.9$

Find the probability of 6 job applications received in a given week.

This is P(X = 6).

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 6) = \frac{e^{-5.9}*(5.9)^{6}}{(6)!} = 0.1605$

16.05% probability of 6 job applications received in a given week.
