Answer:

She can expect 12 green shells.

There are 60 green shells out of a total of 1000; this makes the probability of drawing a green shell 60/1000. If she repeats this process with replacement 200 times, the expected amount of green shells would be

60/1000(200) = 12000/1000 = 12

Answer:

The first amount is larger by 25% or .25a

Step-by-step explanation:

Lets increase a by 50%

The increase is .5a

So the new value is a + .5a = 1.5a

Now we will decrease the new value by 50%

decrease = .5 (1.5a) = .75a

The new value of a is 1.5a - .75a = .75a

a > .75a

a - .75a = .25a

a is bigger than .75a by .25a

. Use the statistical features of your calculator to find the mean and the standard deviation to the nearest tenth of a data set

uysha [10]

Answer:

Mean = 1.9

Standard deviation = 0.6

Step-by-step explanation:

The Mean is calculate by the formula:

$Mean = \frac{\text{Sum of all the observation}}{\text{Total number of observation}}$

⇒ $Mean = \frac{24.9+24.7+24.7+23.4+27.9}{5} = 1.85$

Thus Mean to the nearest tenth is 1.9

Standard Deviation is the square root of sum of square of the distance of observation from the mean.

$Standard deviation(\sigma) = \sqrt{\frac{1}{n}\sum_{i=1}^{n}{(x_{i}-\bar{x})^{2}} }$

where, $\bar{x}$ is mean of the distribution.

Putting all values in the formula, We get

Standard Deviation = 0.597 ≈ 0.6

Suppose a triangle has two sides of length 32 and 35, and that the angle

pantera1 [17]

Answer:

The third side is around 58.043

Step-by-step explanation:

Use the law of cosines: $c^2=a^2+b^2-2abcos(C)$

Plug in the two sides we know (into a and b) and the angle we know (into angle C).

Thus:

$c^2=32^2+35^2-2(32)(35)cos(120)$

Use a calculator:

$c^2=3369\\$

$c=58.043087...$

(Note: Make sure you're in Degrees mode.)
