Answer:
20 degrees and 85 degrees.
Step-by-step explanation:
105 degrees+ 150 degrees is equal to 255 degrees. 360 degrees - 255 degrees is 105 degrees. To get the ratio equivalent to 105 degrees you have to multiply both sides by 5 in order to get 20 degrees, and 85 degrees. I hope this helps! :)
A random number generator is used to create a list of 200 single-digit numbers. of those 200 numbers, 105 are even and ninety-five are odd. seven was generated fifteen times. what is the experimental probability of an odd number other than seven being generated? 40.0% 45.0% 47.5% 52.5%
Using it's concept, it is found that the probability of an odd number other than seven being generated is of 40.0%.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these number of outcomes are taken from previous trials.
In this problem, 200 numbers have been generated, and 80 are odd numbers that are not seven, hence the probability is given by:
p = 80/200 = 0.4 = 40%.

30 Use the method of completing the square to determine the vertex of f(x) = x² - 14x - 15.
State the coordinates of the vertex.
Answer:
x² - 14x - 15 = (x − 7)² − 64Then the coordinates of the vertex are (7 , -64)Step-by-step explanation:
x² - 14x - 15 = x² - 14x + (49 - 49) - 15
= (x² - 14x + 49) - 49 - 15
= (x² - 14x + 7²) - 49 - 15
= (x − 7)² − (49 + 15)
= (x − 7)² − 64
x² - 14x - 15 = (x − 7)² − 64
Then the coordinates of the vertex are (7 , -64)

What is the measure of major B 84° O 276° O252° O 84° O 168 arc AB? A
Answer:
A - 84°
Step-by-step explanation:
The measure of an arc is equal to the measure of the central angle that intersects it.
The central angle of this circle measures 84° and it intercepts arc AB, meaning arc AB measures 84°
How do I graph this linear function
x < -1
This is how the linear function looks.
given that у=6 cm and θ=15 °, work out x rounded to 1 decimal place.
(the diagram is not drawn to scale.)
Using a trigonometric realtion, we can see that x = 23.18cm
How to find the value of x?Here we have a right triangle, we can see that y = 6cm, and the angle theta is 15°.
Notice that y is the opposite cathetus to the known angle, and we want to find the value of x, which is the hypotenuse.
Then we can use the trigonometric relation:
sin(a) = (opposite cathetus)/hypotenuse.
Reaplacing what we know, we will get:
sin(15°) = 6cm/x
Solving that for x:
x = 6cm/sin(15°9
x = 23.18cm

Ava scored 18 points in a basketball game. She scored seven points more than Claire. Let c
be the number of points scored by Claire. Set up an equation that lets you solve for the value
of c.
Answer:
11 points
Step-by-step explanation:
Claire had 11 points because 18-7=11
C+7 =18 is the equation which can be used to find the Claire score C, the value of C is 11.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Ava scored 18 points in a basketball game.
Let Ave score be represented as A.
Ave scored seven points more than Claire.
Let C be the Claire score.
A=7+C
As given Ava scored 18 points in a basketball
so the value of A is 18
18=7+C
Now let us find the value of C
Subtract 7 from both sides
18-7 =C
11=C
Hence, C+7 =18 is the equation which can be used to find the Claire score C, the value of C is 11.

The weight of vegetables transported by a farmer to a nearby market increases by 15% every month.
The farmer transports 460 pounds of vegetables in April, 529 pounds of vegetables in May, 608.35 pounds of vegetables in June, and 699.60 pounds of vegetables in July.
Approximately how many pounds of vegetables will be transported to the market in August
Using proportions, it is found that 804.54 pounds of vegetables will be transported to the market in August.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, considering the weight increases by 15% every month, the August amount will be the July's amount multiplied by 1.15, hence:
A = 1.15 x 699.60 pounds = 804.54 pounds.

The height in feet is modelled by the function below, where the t is in
seconds after the object hit into the air. Appromixmately which time does the object reach the lowest height?
f(t) = -21² +22t + 6
A. 7 seconds
B. 5 seconds
C. 8 seconds
D. 11 seconds
The object reaches the lowest height at 5 seconds
How to determine the time?The function is given as:
f(t) = -2t² +22t + 6
Differentiate the function
f'(t) = -4t +22
Set to 0
-4t +22 = 0
Subtract 22 from both sides
-4t = -22
Divide both sides by -4
t = 5.5
Remove decimal points
t = 5
Hence, the object reaches the lowest height at 5 seconds

Which of the following choices is the value of cscθ given that cosθ= √2/2?
For the cosecant we will get:

So the correct option is the third one.
Which of the following choices is the value of cscθ given that cosθ= √2/2?First, we can write:
[tex]csc(x) = \frac{1}{sin(x)}[/tex]
Now, remember that:
[tex]cos(x) = \frac{\sqrt{2} }{2} \\\\for\ x = \pm \frac{pi}{4}[/tex]
And for the sine we have:
[tex]sin(pi/4) = \frac{\sqrt{2} }{2} \\\\sin(-pi/4) = -\frac{\sqrt{2} }{2} \\[/tex]
Then the cosecant for these possible values of x gives:
[tex]csc(\pm \frac{pi}{4}) = \frac{1}{sin(\pm \frac{pi}{4})} = \pm \frac{2}{\sqrt{2} } = \pm \sqrt{2}[/tex]
So the correct option is the third one.
