Answer:

2^7

Step-by-step explanation:

Dividing fractions with exponents means you subtract, so 2^6/2^4 = 2^6-4 =2^2

Multiplying numbers with exponents means adding the exponents, so 2^2+2^5 = 2^2+5 = 2^7

Mazyrski [523]

Answer:

The number of viewers Network A expects will watch their show is 1.4 million viewers.

Step-by-step explanation:

The expected value is calculated by multiplying the possible outcomes by the probability of their occurrence and adding the results

Therefore, we have the expected value given by the following expression;

Estimated network A viewers where network B schedule top show = 1.1 million viewers

Estimated network A viewers where network B schedule a different show = 1.6 million viewers

Probability that Network B will air its top show = 0.4

Probability that Network B will air another show = 0.6

We therefore have;

Expected value, E of Network A viewers is therefore;

E = 1.1 × 0.4 + 1.6 × 0.6 = 0.44 + 0.96 = 1.4 million viewers.

Network A expects 1.4 million viewers will watch their show.

Can somebody help me with this question please

Answer:

Step-by-step explanation:

Points B,C,D, and E are points on the edge of the circle.

$\angle BCD$ and $\angle BED$ are in the same segment.

We have that: $\angle BCD=34\degree$

We want find $m\angle BED$

Recall that angles in the same segment are congruent.

$\therefore \angle BED=\angle BCD=34$

So the answer is 34

a truck that can carry no more than 6400 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh

Tems11 [23]

I'm not going to do the entire question, but I'll do the first part.

For the first part, you have to set up an inequality. Use context clues, such as no more than (the one used in this sentence) to figure out what the symbol should be for the inequality.
In this case, because it is NO MORE THAN 6400, it would be:

6400 $\leq$ 250r + 475p

where r represents the # refrigerators, and p represents the # pianos

Now that you have the equation, make the graph, then for the 3rd part, plug in 12 and 8 to r and p to see if it keeps the inequality true.

Hope this helps! :)
