7 0

Answer:

x = 12

Step-by-step explanation:

The sum of a heptagon interior angles is 900 degrees, so:

10x + 5 + 12x - 9 + 9x + 14 + 133 + 10x + 9 + 10x + 136 = 900

rearrange to make it easier to subtract/add, u don't have to do this it's optional

10x + 12x + 9x + 10x + 10x + 5 - 9 + 9 + 14 + 133 + 136 = 900

add liket terms

22x + 29x + 19 + 269 = 900

51x + 288 = 900

subtract 288 from both sides

51x = 612

divide by 51

x = 12

In a large population, about 10% of people do not like the taste of cilantro, an herb used in cooking. A researcher takes a rand
bogdanovich [222]

Answer:

0.0019390

Step-by-step explanation:

10% of people do not like the taste of cilantro

A researcher takes a random sample of 15 people and surveys whether they like cilantro

Use the binomial distribution to compute the probability that exactly 6 of the people in the sample do not like cilantro.

Probability of success = 0.10 = p

Probability of failure = 0.9 =q

n = 15

r = 6

Formula : P(X=r)=^nC_rp^r q^{n-r}

P(X=6)=^{15}C_6 (0.1)^6 (0.9)^{15-6}

P(X=6)=\frac{15!}{6!(15-6)!} (0.1)^6 (0.9)^{15-6}

P(X=6)=0.0019390

Hence  the probability that exactly 6 of the people in the sample do not like cilantro is 0.0019390

What is 27.08361513 rounded to the nearest tenth?
Wittaler [7]

Answer:

27.1

Step-by-step explanation:

Rounding off to the nearest tenths = the value should be written correctly to <u>one</u> decimal place. The tenth place value in a decimal number is the first number which comes first after the decimal point. For this, we need to observe the hundredth number (the number which comes second after the decimal point). If this number is greater than or equal to 5, we add 1 to the tenth value. If it is less than 5, we leave the tenth place value as it is, and remove all the numbers present after this number.
