Mathematics
1 answer:
adelina 88 [10]2 years ago
8 0

Answer:

3x + 6y

Step-by-step explanation:

so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y

The bearing of point B from point A is 064°.<br> Find the bearing of point A from point B.
Alex777 [14]

Answer:

The bearing of A from B is 296 degrees

Step-by-step explanation:

Here, we want to find the bearing of point A from point B

To find the bearing of point A from B, we simply subtract the bearing of B from A from 360

Mathematically, that will be;

360 - 64 = 296 degrees

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.
lesya [120]

Answer:

0.5 ; 0.475 ; 0.689 ; 0.4013

Step-by-step explanation:

Given that:

Rate of production of defective batteries p = 0.05

Number of batteries produced (n) = 10

The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries

Variance of defective batteries :

Var(X) = n * p * q ; q = 1 - p

Hence,

Var(X) = 10 * 0.05 * 0.95 = 0.475

Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689

Probability that atleast 1 battery is defective :

Using the binomial probability function

P(x ≥ 1) = 1 - p(x = 0)

= 1 - q^n

= 1 - 0.95^10

= 1 - 0.59873693923837890625

= 0.40126306076162109375

= 0.4013

Nina's garden is 4 1/5 meters long and 3/qo meters wide. What is the area of Nina's garden?
olga2289 [7]

Answer: 63/50 meters^2 or in mixed number 1 13/50 meters^2

Step-by-step explanation:

area= length x width

length = 4 1/5= 21/5 . multiply the whole number with the denominator 4x5= 20 add 20 with the numerator 20+1=22

width = 3/10

21/5 x 3/10 ( multiply the denominators together)

21x3 / 5x10

= 63/50 meters^2 or in a mixed number 1 13/50 meters^2

(by the way I'm guessing you meant 3/10 and not 3/q0)
