Answer:

8x - 20

Step-by-step explanation:

3(x - 6) + 4 + 5x - 6 $\longmapsto$ Distribute 3 to (x - 6)

3(x) - 3(6) + 4 + 5x - 6

3x - 18 + 4 + 5x - 6

Simplify:

3x + 5x - 18 + 4 - 6

8x -18 - 2

8x - 20

HELP ASAP Store A sells 5 bagels for $2.05. Store B sells 3 bagels for $1.35. How do the unit rates compare?

Crank

Step-by-step explanation:

Store A:

5 bagels for $2.05, 1 bagel for $2.05/5 = $0.41.

Store B:

3 bagels for $1.35, 1 bagel for $1.35/3 = $0.45.

Hence the bagels at Store B are $0.04 more expansive than the bagels at Store A. (C)

The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval fro

PtichkaEL [24]

Answer:

$P( X > 46) = 0.7 \ minute$

$\mu = 42 \ minute$

Step-by-step explanation:

From the question we are told that

The procedure for performing a certain task is uniformly distributed on the interval from( a = 32 )minutes to (b= 52) minutes

Generally the cumulative distribution function for continuous uniform distribution is

$F(x) = \left \{ {{0 \ \ \ \ \ for \ x \ x < a} \atop {\frac{x-a}{b-a} } \ \ for \ a \le x \ge b} \atop {1 \ \ \ \ \ \ \ for \ x > b }\right.$

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

$P( X > 46) = F(46) = \frac{46 - 32}{52-32}$

=> $P( X > 46) = 0.7 \ minute$

Generally the average time required to learn the procedure is mathematically represented as

$\mu = \frac{a + b}{2}$

=> $\mu = \frac{32 + 52}{2}$

=> $\mu = 42 \ minute$
