Answer:

Option C $\frac{1}{2}(185\°-x\°)=76\°$

Step-by-step explanation:

we know that

The measurement of the <u>exterior angle</u> is the semi-difference of the arcs it comprises

$76\°=\frac{1}{2}(arc\ ST-arc\ XZ)$

we have

$arc\ ST=185\°$

$arc\ XZ=x\°$

substitute

$76\°=\frac{1}{2}(185\°-x\°)$

Rewrite

$\frac{1}{2}(185\°-x\°)=76\°$

Answer:

0.0367 = 3.67% probability that exactly 6 patients will die

Step-by-step explanation:

The patients are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this question, we have that:

20 patients means that $N = 20$

Sample of 8 means that $n = 8$

9 have the heart problem, so $k = 9$

What is the probability that exactly 6 patients will die?

This is P(X = 6).

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 6) = h(6,20,8,9) = \frac{C_{9,6}*C_{11,2}}{C_{20,8}} = 0.0367$

0.0367 = 3.67% probability that exactly 6 patients will die

The image of the point P(-3, 2) under the translation (2/1) is

marin [14]

The image of the point P(-3, 2) under the translation T<2,1> is (-1, 3)

<h3>How to determine the image of the translation?</h3>

The coordinate point is given as:

P = (-3, 2)

The translation is given as

T<2,1>

The translation can be represented as:

(x, y) = (x + 2, y + 1)

So, we have the following equation

P' = (-3 + 2, 2 + 1)

Evaluate the sum

P' = (-1, 3)

Hence, the image of the point P(-3, 2) under the translation T<2,1> is (-1, 3)

mrs.johnson gave a sum of money to her son and daughter in the ratio 5:6. her daughter received $2,400.how much did mrs.johnson

marin [14]

If the daughter got 2,400, then the son got 2,400 * $\frac{5}{6}$ (we divide what she got into six parts and give him 5 of such parts: this is

2,400 * $\frac{5}{6}$ = 400*5=2000

and together they got 2000+2400=4400

which is the answer
