a player gets to throw 4 darts at the target shown. Assuming the player will always hit the target, the probability of hitting an odd number three times is *blank* times more than the probability of hitting an even number 3 times
Answers
Answer: The probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.
Step-by-step explanation:
From the given picture , the total total number of sections in the spinner = 5
Sections having Odd numbers = 3
Sections having Even numbers =2
We know that , [tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
So , probability of hitting an odd number = [tex]\dfrac{3}{5}[/tex]
Probability of hitting an even number = [tex]\dfrac{2}{5}[/tex]
Since all events are independent of each other ,
So , probability of hitting an odd number three times = [tex](\dfrac{3}{5})^3=\dfrac{27}{125}[/tex]
Probability of hitting an even number three times = [tex](\dfrac{2}{5})^3=\dfrac{8}{125}[/tex]
Divide [tex]\dfrac{27}{125}[/tex] by [tex]\dfrac{8}{125}[/tex] , we get
[tex]\dfrac{27}{125}\div\dfrac{8}{125}\\\\=\dfrac{27}{125}\times\dfrac{125}{8}=\dfrac{27}{8}=3\dfrac{3}{8}[/tex]
Hence, the probability of hitting an odd number three times is [tex]3\dfrac{3}{8}[/tex] times more than the probability of hitting an even number 3 times.

How does tan 135 degrees compare to tan -135 degrees
Answers
tan 135=tan(135+180)=tan 315=-1
next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive
Tan(135°) is -1 because it lies in the second quadrant with sine positive and cosine negative, whereas tan(-135°) is 1 as it falls in the third quadrant with both sine and cosine negative. Thus, tan(135°) = -1 and tan(-135°) = 1.
1. The tangent of an angle is defined as the ratio of the sine to the cosine of that angle: tan(θ) = sin(θ) / cos(θ). The tangent function is also periodic with a period of 180 degrees, meaning tan(θ) = tan(θ + 180°).
2. First, let’s find the value of tan(135°). Since 135° is in the second quadrant where sine is positive and cosine is negative:
sin(135°) = sin(180° - 45°) = sin(45°) = √2/2cos(135°) = cos(180° - 45°) = -cos(45°) = -√2/23. Therefore, tan(135°) = (√2/2) / (-√2/2) = -1.
4. Next, we consider tan(-135°). Since -135° is in the third quadrant where both sine and cosine are negative:
sin(-135°) = -sin(135°) = -√2/2cos(-135°) = cos(225°) = -√2/25. So, tan(-135°) = (-√2/2) / (-√2/2) = 1.
In summary, tan(135°) = -1 and tan(-135°) = 1.

Daisies cost $0.99 each and tulips cost $1.15 each. Maria bought a boquet of daisies and tulips. It contained 12 flowers and cost $12.52. Find the number of daisies and the number tulips in the bouquet
Answers
Maria bought 8 daisies and 4 tulips in the bouquet.
Explanation:Let's assume that Maria bought x daisies and y tulips. Since the total number of flowers in the bouquet is 12, we can write the equation: x + y = 12.
Also, the total cost of the bouquet is $12.52. Using the cost per flower, we can write another equation: 0.99x + 1.15y = 12.52.
Now we have a system of equations that we can solve. Multiplying the first equation by 0.99, we get 0.99x + 0.99y = 11.88. Subtracting this equation from the second equation eliminates the x term, giving us 0.16y = 0.64. Dividing both sides by 0.16, we find that y = 4.
Substituting this value back into the first equation, we can solve for x: x + 4 = 12, x = 8.
Therefore, Maria bought 8 daisies and 4 tulips in the bouquet.

Tree a lived for 6 decades and 5 years. Tree b lived for 58 years. Which tree lived longer
Answers
Final answer:
Tree A, which lived for 65 years (6 decades and 5 years), lived longer than Tree B, which lived for 58 years.
Explanation:
To answer which tree lived longer, we can calculate the age of both trees. Tree A lived for 6 decades and 5 years. Since one decade is equal to 10 years, 6 decades would be 6 x 10 years, which is 60 years. Adding the additional 5 years, Tree A lived for a total of 60 + 5 = 65 years.
Tree B lived for 58 years. Comparing both ages, Tree A lived for 65 years while Tree B lived for 58 years. Therefore, Tree A lived longer than Tree B.

which of the following angles is coterminal with 480°
Answers
or
480⁰-360⁰=120⁰
You need to remove all 360 angles, sometimes it can be more than one in it.
Coterminal angle is 120⁰.
An angle coterminal with 480° can be found by subtracting multiples of 360° from 480°. Two examples of such angles are 120° and -240°.
Explanation:To find an angle that's coterminal with a given angle, we can add or subtract multiples of 360° (since a full circle is 360°). So, to find an angle coterminal with 480°, we can subtract 360° from 480°, which gives us 120°. Therefore, 120° is an angle that is coterminal with 480°. It's worth noting that there can be infinite coterminal angles, both positive and negative, for any given angle. For example, if we subtract 360° again from 120°, we get -240°, which is also coterminal with 480°.

A Spanish class has 28 a total of students. The number of females is 4 less than the number of males. How many males and how many females are in the class?
Answers
F + M = 28
F = M - 4
Now we can solve for M by substitution. In the first equation, replace F with (M - 4):
(M - 4) + M = 28
Combine like terms and solve for M:
2M - 4 = 28
2M = 32
M = 16
If there are 16 males, we can solve for the number of females by plugging 16 back into one of the equations:
F = 16 - 4 = 12
There are 16 males and 12 females.
[tex]x + y = 28[/tex]
[tex]x = y + 4[/tex]
x represents the males in the class, and y represents the females in the class.
Because x = y + 4, we can substitute x in the first equation:
[tex]x = y + 4[/tex]
[tex]y + 4 + y = 28[/tex]
Combine like terms.
[tex]2y + 4 = 28[/tex]
Subtract 4 from both sides.
[tex]2y = 24[/tex]
Divide both sides by 2 to get y by itself.
[tex]y = 12[/tex]
Because we know what y is, we can plug in its value into the first equation:
[tex]x + 12 = 28[/tex]
Subtract 12 from both sides to get x by itself.
[tex]x = 16[/tex]
There are 16 males and 12 females in the class.

Lila draws a 145 degree angle. then she divides it into three smaller angles. One of the smaller angles measures 65 degrees, then the other two are equal in measure. What is the measure of the other two.
Answers
Let each of the equal small angles be x.
The sum of three small angles is 145 degrees. One of these small angles is 65 degrees.
Now let us substitute the given information in an equation.
[tex]2x+65=145[/tex]
After subtracting 65 from both sides of equation we get
[tex]2x=80[/tex]
Dividing both sides of equation with 2 we get
[tex]x=\frac{80}{2}=40[/tex]
Therefore measure of each of the remaining angles is 40 degrees.
The measure of the other two smaller angles, given that they are equal would be 40 degrees.
How to find the measure of angles ?Let's denote the measure of the other two smaller angles as "x."
We know that the sum of the three angles should be equal to the original 145-degree angle. Therefore, we can set up the equation:
65 + x + x = 145
Simplifying the equation:
65 + 2x = 145
Next, we can isolate "x" by subtracting 65 from both sides of the equation:
2x = 145 - 65
2x = 80
Finally, we divide both sides of the equation by 2 to solve for "x":
x = 80 / 2
x = 40
So, the measure of the other two smaller angles is 40 degrees each.

Answers
We have a perpendicular(opposite side), the measure of angle and we are interested in finding the hypotenuse.
sine of the angle relates its perpendicular side to hypotenuse as:
sin(x) = perpendicular/hypotenuse
⇒
Hypotenuse = Perpendicular/sin(x) = 13/sin(70) = 13.8 feet
This means, the length of the ladder is 13.8 feet, rounded to nearest tenth.
Answer:
4.7 ft.
Step-by-step explanation:
Let x represent the distance of the bottom of the ladder from the base of the house.
We have been given that Eric leans a ladder against the roof of his house so that the ladder forms a 70 angle with the ground. The roof of the house is 13 feet above the ground.
Upon looking at our attached graph we can see that ladder and wall of house forms a right triangle with respect to ground, where x is adjacent and side with 13 ft length is opposite side to the angle of 70 degrees.
We know that tangent relates opposite side of a right triangle with adjacent, so we can set an equation as:
[tex]\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}[/tex]
[tex]\text{tan}(70^{\circ})=\frac{13}{x}[/tex]
[tex]x=\frac{13}{\text{tan}(70^{\circ})}[/tex]
[tex]x=\frac{13}{2.747477419455}[/tex]
[tex]x=4.7316\approx 4.7[/tex]
Therefore, the bottom of ladder is 4.7 feet away from the base of the house.
