X + 5 < –4 Solve for x. Answer must be simplified.

Monica [59]

Answer:

x < -9

Step-by-step explanation:

Hi there,

To isolate the variable x, you do the same steps like solving a regular equation.

x + 5 < -4 ← subtract 5 from both sides to make x by itself

x < -9 ← final answer (already in simplest form)

Hope this explanation helps. Cheers.

A commuter crosses one of three bridges, A, B, or C, to go home from work. The commuter crosses bridge A with probability 1/3, c

mihalych1998 [28]

Answer:

0.1333 = 13.33% probability that bridge B was used.

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Arrives home by 6 pm

Event B: Bridge B used.

Probability of arriving home by 6 pm:

75% of 1/3(Bridge A)

60% of 1/6(Bridge B)

80% of 1/2(Bridge C)

$P(A) = 0.75*\frac{1}{3} + 0.6*\frac{1}{6} + 0.8*\frac{1}{2} = 0.75$

Probability of arriving home by 6 pm using Bridge B:

60% of 1/6. So

$P(A \cap B) = 0.6*\frac{1}{6} = 0.1$

Find the probability that bridge B was used.

$P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.1}{0.75} = 0.1333$

0.1333 = 13.33% probability that bridge B was used.

5/8-11/20=? Help what’s the answer I’m stuck on finding the LCM of the denominators

zhannawk [14.2K]

Answer:

3/40

Step-by-step explanation:

$\frac{5}{8} - \frac{11}{20}$
$\frac{25}{40} - \frac{22}{40}$ (LCM is 40)
$\frac{25-22}{40}$
$\frac{3}{40}$

Therefore, the answer is 3/40!
