Answer:
the percentage change on the drone is 42.86%
Step-by-step explanation:
The computation of the percentage change is shown below:
Since the helicopter was sold for $179.99
But amazon would be selling it for $125.99
So, the percentage change would be
= (Sale value - sale value by amazon) ÷ ( sale value by amazon) × 100
= ($179.99 - $125.99) ÷ ($125.99) × 100
= 42.86%
Hence, the percentage change on the drone is 42.86%

Step-by-step explanation:
an astronaut drops a rock off the edge of a cliff on the moon. the distance, d(t), in meters, the rock travels after t seconds can be modeled by the function d(t) = 0.8t^2. what is the average speed, in meters per second, of the rock between 5 & 10 seconds after it was dropped?
Answer:
The average speed between the times given is 12 m/s
Step-by-step explanation:
Here, we want to calculate rate of change between the times given
Mathematically , we can get the average rate of change using the formula
f(b)-f(a)/b-a
in this case, b = 10 s and a = 5 s
f(b) is d(10) = 0.8(10)^2 = 80
f(a) is d(5) = 0.8(5)^2 = 20
Rate of change is thus;
(80-20)/(10-5) = 60/5 = 12 m/s

NEED TO FIND THE MEAN
Answer:
mean=2.6
Step-by-step explanation:
1+3+4+4+1=13
13 divided by 5=2.6
Answer:mean= 2.6=13/5
Step-by-step explanation:
mean=sum of all values/number of values
so,
mean=(1+3+4+4+1)/5
mean=13/5=2.6

which of the following lengths cannot be the lengths of a triangle? 4,6,9 a.) 3,4,2 b.) 2,2,3 c.) 1,1,2 d.)
Answer:
D. 1, 1, 2
Step-by-step explanation:
A triangles sides have to have the two smallest side's sum add up to be greater than the largest number. In D, 1+1 = 2, and 2 is the largest number, since 2 is not greater than 2, It cannot be a triangle.

Which statement about the quadratic equation below is true?
2x2 - 15x + 18 = 0
Answer:
x=3/2 or x=6
Step-by-step explanation:
2x2−15x+18=0
Step 1: Factor left side of equation.
2x^2-12x-3x+18=0
taking common factors
2x(x-6)-3(x-6)=0
(2x−3)(x−6)=0
Step 2: Set factors equal to 0.
2x−3=0 or x−6=0
x=3/2 or x=6
Find the probability of rolling a 5 or greater on the first die and a 2 or greater on the second die
Answer:
The probability is 1/9
Step-by-step explanation:
The probability of rolling a 5 the first time is 1/6
The probability of rolling a number greater than 2
Numbers greater than 2 are 3, 4, 5, 6
So the probability of rolling a number out of these four is 4/6
So the probability of rolling a five for the first time and the probability of rolling a number greater than 2 the second time will be
1/6 * 4/6 = 4/36 = 1/9
Answer:
1/3, 5/6, and 5/18.
Step-by-step explanation:
If a die has 6 sides, then because there are 2 sides equal or greater than 5 (5 and 6), then there is a 2/6 or 1/3 chance of rolling the first die. On the second roll, there are 4 sides equal or greater than 5 (2, 3, 4, 5, and 6), so there is a 5/6 chance of rolling it. To find the probability of both happening, multiply 1/3 by 5/6 to get 5/18.

Kyra is finding the area of the circle. She cuts the circle into equal sectors and arranges them into the shape of a parallelogram. A circle is cut into 8 equal sections. The sections are arranged into the shape of a parallelogram with a base of 9.42 inches and height of 3 inches. Which expression represents the approximate area of the circle in square inches? 9.42 times 3 9.42 times 3 squared 9.42 times 6 9.42 times 6 squared]
Answer:
The expression that represents the approximate area of the circle in square inches is;
9.42 times 3
Step-by-step explanation:
From the question, we have;
The shape of the figure which Kyra is finding the area for = A circle;
The number of equal pieces Kyra cuts the shape into = 8 equal sectors
The shape the sectors are arranged into = A parallelogram
The base of the parallelogram = 9.42 inches
The height of the parallelogram = 3 inches
Therefore, the area of the approximate parallelogram formed ≈ The area of the circle
The area of a parallelogram = The base × The height
∴ The area of the approximate parallelogram formed = 9.42 × 3 ≈ The area of the circle
The approximate area of the circle = 9.42 × 3 square inches.

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has two opportunities for a two-point conversion. He misses the first attempt 50% of the time. When he misses the first attempt, he misses the second attempt 15% of the time. What is the probability of missing both two-point conversion attempts?
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075
you probably didn't want the nerdy stuff but oh well
