$\tt Step-by-step~explanation:$

To solve for x, we need to know that the angles inside of a triangle is always equal to 180º.

$\tt Steps:$

Since all the angles added together are equal to 180º, we simply have to add the two given angles and subtract that from 180º.

$\tt 43+60=103\\180-103=77\\x=77$

$\large\boxed{\tt Our~final~answer: ~x=77}$

Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on

FinnZ [79.3K]

The question is incomplete! Complete question along with answers and step by step explanation is provided below.

Question:

(a) Binomial probability distributions depend on the number of trials n of a binomial experiment and the probability of success p on each trial. Under what conditions is it appropriate to use a normal approximation to the binomial? (Select all that apply.)

nq > 10

np > 5

p > 0.5

np > 10

p < 0.5

nq > 5

(b) What is the probability of "12" or fewer successes for a binomial experiment with 20 trials. The probability of success on a single trial is 0.50. Use the normal approximation of the binomial distribution to answer this question. (Round your answer to four decimal places.)

Answer:

(a) The correct options are np > 5 and nq > 5

(b) P(x ≤ 12) = 0.8133

Step-by-step explanation:

Plz help i just started pretty confused

Elina [12.6K]

Answer:

right

neither

straight

neither

Step-by-step explanation:

The first angle is a right angle. The box in the corner indicates a 90 degree angle

The second angle is less than 90 degrees so it is an acute angle

The third angle is a straight line so it is a straight angle.

The fourth angle is wider than 90 degrees it is an obtuse angle

Factor the following equation to find its zeros. y = x² - 36

alukav5142 [94]

Answer:

x = 6, x = - 6

Step-by-step explanation:

Given

y = x² - 36

To find the zeros let y = 0, that is

x² - 36 = 0 ← x² - 36 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b), thus

x² - 36 = 0

x² - 6² = 0

(x - 6)(x + 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 6 = 0 ⇒ x = - 6
