Answer:

(a)x=128 degrees

(b) $\angle APD\neq 116^\circ$

Step-by-step explanation:

$\angle ABD+\angle CBD =180^\circ$ (Linear Postulate)\\\angle ABD+116^\circ =180^\circ\\\angle ABD=180^\circ-116^\circ\\\angle ABD=64^\circ$

(a) Now:

$\angle AOD=2 \times \angle ABD$ (Angle at the centre is twice the angle at the circumference)\\x=2 \times 64^\circ\\x=128^\circ$

(b)

$\angle APD=2 \times \angle ABD$ (Inscribed Angle Theorem)\\\angle APD=2 \times 64^\circ\\ \angle APD=128^\circ$

$\angle APD\neq 116^\circ$

If there were 5 million births in a particular country and 3 comma 375 sets of naturally occurring triplets, what is the experi

IgorLugansk [536]

Answer:

$Probablity =P=6.75*10^-^4$

Step-by-step explanation:

The experimental probability can be defined as the ratio of the number of times any particular event has occurred to the total number of times that event has taken place.

Experimental probability = P = No. of event occurrences / total number of occurrences.

In our question statement,

No of naturally occurring triplets are = 3375

Total number of births = 5 million = 5,000,000

Putting values in equation.

$P=3375/5000000$

$P = 0.000675\\P=6.75*10^-^4$

Liz earns a salary of $2,100 per month, plus a commision of 5% of her sales. She wants to earn at least $2,400 this month. Writ

vladimir2022 [97]

(2,100*1)+(x*.05)=2,400

The first part is her salary per month multiplied by one month. The second part is her sales times the commission rate. Finally the last part is her ending earning goal.

Hope this helped!
