The length of a planet's orbit around a star is approximately 17,650,000 km.
It takes the planet about 640 Earth days to complete a full orbit.
What is the planet's average speed in kmh-1 to 3sf?
Answers
Answer:
1150 km/hr
Step-by-step explanation:
Formula for Average Speed is given as = Distance in Kilometers/ Time in Hours
In the question we are given the following parameters.
The length of a planet's orbit around a star = Distance = 17,650,000 km.
Time taken to complete a full orbit = 640 Earth days
Step 1
We need to convert the time in days to hours
1 Earth day = 24 hours
640 Earth days =
We cross multiply
640 Earth days × 24 hours
= 15360 hours.
Step 2
Average Speed = Distance in Kilometers/ Time in Hours
Average Speed = 17,650,000 km. /15360 hours
Average Speed = 1149.0885417 km/hr
Approximately to 3 significant figures=
1150 km/hr
Therefore, the planets average speed in kmh-1 to 3sf is 1150 km/hr

Answers
Answer:
(2x³-5x²-24x+63)π
Step-by-step explanation:
According to the formula, it would be (x-3)²(2x+7)π. Expanding (x-3)², you would get (x-3)(x-3) which equals x²-3x-3x+9 which equals x²-6x+9. Now you have (x²-6x+9)(2x+7). Expanding it would equal 2x³+7x²-12x²-42x+18x+63. Combining like terms would result in 2x³-5x²-24x+63. You have to multiply it all by pi so the answer is (2x³-5x²-24x+63)π.

The sum of two numbers is −21. One number is 55 less than the other. Find the numbers.
Answers
Answer:
x = 17 y= -38
Step-by-step explanation:
x + y = -21
y = x - 55
It doesn't matter whether x or y is 55 less than the other right now.
substitute for y:
x + x - 55 = -21
solve for x:
2x = 34
x = 17
solve for y:
17 + y = -21
y = -38

Step-by-step explanation:
he count of numbers from 1 to n that are divisible by k is integer part of (n/k).
So the numbers from 1 to 99 divisible by 3 is int(99/3) = 33
Those divisible by 5: int(99/5) = 19
From the sum of those two, subtract those divisible by 15 = int(99/15) = 6
That gives you 33+19-6 = 46.
Now subtract the 1 digit numbers: 3, 5, 6, 9, or four of them

Step-by-step explanation:
[tex] S_n = \dfrac{a(1 - r^n)}{1 - r} [/tex]
a = first term
r = common ratio
n = number of terms
Here we have
a = 1
r = 2
n = 10
[tex] S_{10} = \dfrac{1(1 - 2^{10})}{1 - 2} [/tex]
[tex] S_{10} = \dfrac{1 - 1024}{-1} [/tex]
[tex] S_{10} = \dfrac{-1023}{-1} [/tex]
[tex] S_{10} = 1023 [/tex]
Of course, since 10 is not such a large number of terms, you can simply do this:
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 = 1023

D)
0.37
38
Answers
The probability of liking math given that they don't take music is 0.37 option (D) 0.37 is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
The probability:
P(Math/Music') = P(Math∩Musci')/P(Music')
Total number of sample = 22+80+45+38 = 185
Probability of liking math:
P(Math) = (22+80)/185 =0.55
Probability:
P(Music) = (45+80)/185 = 0.68
P(Music') = 1-0.68 = 0.32
Probability of liking math and liking music:
P(Math∩Music) = 80/185 = 0.43
Now, P(Maths/Music) = (0.55 - 0.43)/0.32 = 0.375 ≈ 0.37
Thus, the probability of liking math given that they don't take music is 0.37 option (D) 0.37 is correct.

Megan has a bag containing 5 pink marbles, 3 orange marbles, 6 green marbles, and 2 yellow marbles.
Megan started to develop a probability model. Here is the sample space.
S = {P, P, P, P, P, O, O, O, G, G, G, G, G, G, Y, Y}
Part A
put in order where it would go on the table 2/16, 3/16, 5/16, 6/16
Help Megan complete the model by assigning probabilities to the four listed events. Drag each fraction to the correct probability.
Part B
Suppose Megan drew a marble 80 times. Estimate how many times she should expect to draw an orange marble. Megan would draw an orange marble ____
times.
Answers
Step-by-step explanation:
To find the probability
Total marbles = 5 + 3 + 6 + 2 = 16
P pink = 5/ 16
P orange = 3/16
P green = 6/ 16 = 3/8
P yellow = 2/16 = 1/8
Part B when we divide 80 by 16 = 5
So she drew every marble 5 times
So 3 x 5 = 15
She drew the orange marble 15 times
