Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are rando

qwelly [4]

Answer: The probability that both televisions work is 0.5625 .

The probability at least one of the two televisions does not work is 0.4375.

Step-by-step explanation:

Given : Number of televisions received in shipment= 12

Number of defective televisions received in shipment= 3

Then proportion of defective televisions = $\dfrac{3}{12}=0.25$

Using binomial probability formula, the probability of getting success in x trials is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$

If two televisions are randomly selected, then the probability that both televisions work will be :-

$P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625$

The probability at least one of the two televisions does not work will be :-

$P(x\geq1)=1-P(0)=1-0.5625=0.4375$

Tell whether the pair of polygons is similar. Explain why or why not.

Savatey [412]

9514 1404 393

Answer:

not similar

Step-by-step explanation:

Similar polygons have all corresponding angles congruent, and corresponding sides proportional.

The sides lengths guarantee the polygons are parallelograms, so one pair of angles being congruent is sufficient to ensure that all corresponding angles are congruent.

The ratio of side lengths in the left polygon is 13/8, and the ratio of side lengths in the right polygon is 5.2/2.4 = 13/6. These are different ratios, so the corresponding sides are NOT proportional.

The figures are NOT SIMILAR.

What are the units for the variable in the following scenario?

krek1111 [17]

Answer:

Her grocery bill was $4.62.

Step-by-step explanation:

There is some mistake in question so the correct question is:

Sherry bought 6 apples at 43¢ per apple. She then bought 4 oranges at 51¢ per orange. How much was her grocery bill?

Now, to find the grocery bill.

As the units are given:

43¢ per apple and

51¢ per orange.

$1 = 100¢.

So, the cost of 6 apples = $0.43\times 6=2.58$

Thus, the cost of 6 apples = $2.58

And the cost of 4 oranges = $0.51\times 4=2.04$

Thus the cost of 4 oranges = $2.04

Now, to get the total grocery bill we add the cost of apples and oranges:

$\$2.58+\$2.04$

$=\$4.62$

Therefore, her grocery bill was $4.62.
