Check the picture below.
let's notice that the angle -150° has a reference angle of 30°, so any trigonometric function for either angle will be the same value, however, let's recall that the sine or y-coordinate is negative on the III Quadrant, so sin(-150°) is the same as sin(30°) BUT negative, -sin(30°).
Answer: (A) 30%
Step-by-step explanation:
Given : The probability that a bird will lay an egg =0.75
The probability that the egg will hatch =0.50
Now, the probability that the egg will lay an egg and hatch = 
Also,The probability that the chick will be eaten by a snake before it fledges =0.20
Then, the probability that the chick will not be eaten by a snake before it fledges : 1-0.20=0.80
Now, the probability that a parent will have progeny that survive to adulthood will be :-
Hence, the probability that a parent will have progeny that survive to adulthood = 30%
A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. The length of Jk can be either 10 or 26.
<h3>What is a rectangle?</h3>
A parallelogram in which adjacent sides are perpendicular to each other is called a rectangle. A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.
Since in a rectangle the opposite sides are equal, therefore, the sides NM and JK will be equal.
JK = MN
8x - 14 = x² + 1
0 = x² - 8x + 15
x = 5, 3
Hence, the length of Jk can be either 10 or 26.
The complete questions are:
Quadrilateral JKMN is a rectangle, if NM= 8x - 14 and JK= x squared + 1, find JK.

Answer: I think it's The Third Point Unsure
<span>You are given
John Davis’ rate which is $9.75 an hour. It is said that he works for four
hours on Monday, six hours on Tuesday, five hours on Wednesday, five hours on
Thursday, and seven hours on Friday. You are asked to find the gross pay of John
Davis. All you need to do is to multiply the rate to the hour of work.</span>
<span>
Monday: $9.75(4h)
= $39</span>
Tuesday:
$9.75(6h) = $58.5
Wednesday:
$9.75(5h) = $48.75
Thursday:
$9.75(5h) = $48.75
Friday:
$9.75(7h) = $68.25
<span>
To get the
gross pay, add everything and you will get $263.25. The answer is letter D.</span>
