Answer: 6.6

Step-by-step explanation: To round, look to the number in the place value beside the place value given. In yours, look to the hundredths place because it's to the right of the tenths place. In the number is 5 or more, add one to the given place value. 4 or less, leave it alone and as is. After the given value, make everything a zero.

ira [324]

Answer:

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$

Step-by-step explanation:

There are

639 plants with white flowers
280 plants with purple flowers
919 plants in total.

The <u>empirical probability</u> of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

The emperical probability of being a plant with white flower is

$\dfrac{639}{919}\approx 0.695$

The emperical probability of being a plant with purple flower is

$\dfrac{280}{919}\approx 0.305$

If a fair coin is tossed four times, what is the probability of it landing heads up at least three times

garri49 [273]

The probability of it landing heads up at least three times is 1/4.

According to the statement

We have a given that the coin is tossed 4 times And we have to find the probability of it landing heads up at least three times.

So, we know that the

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1.

So, According to the statement

Coin is tossed 4 times and we have to probability of find heads three times it means n = 3.

To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin.

Thus there are only 4 outcomes which have three heads.

The probability is 4/16 = 1/4.

So, The probability of it landing heads up at least three times is 1/4.

shusha [124]

Answer:

$f'(x) = {e}^{x}( \sin x + \cos x )$

Step-by-step explanation:

$f(x) = {e}^{x} \sin x \\ \\ f'(x) = \sin x \frac{d}{dx} {e}^{x} + {e}^{x} \frac{d}{dx} \sin x \\ \\ f'(x) = \sin x \: {e}^{x} +{e}^{x} \cos x \\ \\ f'(x) = {e}^{x}( \sin x + \cos x )$
