Answer:

1/2a + 29/12b

Step-by-step explanation:

$\frac{5}{6}a$ + $\frac{3}{4}b$ - $\frac{1}{3}a$ + $\frac{5}{4}b$

(5/6a + -1/3a) + (3/4b + 5/3b)

A product is made up of three parts that act independently of each other. If any of the parts is defective, the product is defec

natali 33 [55]

Answer:

The probability that a product is defective is 0.2733.

Step-by-step explanation:

A product consists of 3 parts. If any one of the part is defective the whole product is considered as defective.

The probability of the 3 parts being defective are:

P (Part 1 is defective) = 0.05

P (part 2 is defective) = 0.10 P (part 3 is defective) = 0.15

Compute the probability that a product is defective as follows:

P (Defective product) = 1 - P (non-defective product)

= 1 - P (None of the 3 parts are defective)

= 1 - P (Part 1 not defective) × P (Part 2 not defective) × P (Part 1 not defective)

$=1-[(1-0.05)\times(1-0.10)\times (1-0.15)]\\=1-[0.95\times0.90\times0.85]\\=1-0.72675\\=0.27325\\\approx0.2733$

Thus, the probability that a product is defective is 0.2733.

Two years ago a man was six times as old as his daughter. In 18 years he will be twice as old as his daughter. Determine their p

Troyanec [42]

Answer:

Step-by-step explanation:

f- 2 = 6(d-2)

f - 2 = 6d - 12

f = 6d - 12 + 2

f = 6d - 10 .................................... eq 1

f + 18 = 2(d+18)

f + 18 = 2d + 36

f= 2d + 36 - 18

f = d + 18 .......................................... eq 2

eq1=eq2

6d - 10 = 2d + 18

6d - 2d = 18 + 10

4d = 28

d = 28/4

d = 7 yrs is the daughter's age

Take eq 1

f = 6(7) - 10

f = 42 - 10

f = 32 yrs is Father's age

Alja [10]

Answer:

1) distributive property

2) subtraction property of equality

3) division property of equality

Step-by-step explanation:

Given : If $\frac{1}{2}(8x+14)=39$ , then x=8

To complete the proof :

Solution :

Following are the complete steps or proof of solving the given expression,

$\frac{1}{2}(8x+14)=39$ is given

$4x + 7 = 39$ - distributive property

$4x = 32$ - subtraction property of equality

$x = 8$ - division property of equality
