d = 12.25
Step-by-step explanation:
d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2
P1(0, 0, 0) P2(-1, 7, -10)
Substitute the values in the above equation and you will get
d = √(-1 - 0)^2 + (7 - 0)^2 + (-10 - 0)^2
= √(1 + 49 + 100)
= √150

Answer: 11 goes in the blank in the denominator
The probability as a fraction is 5/11
============================================================
Explanation:
There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.
Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.
Let A = 250 and B = 550.
A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominatorThe fraction A/B = 250/550 fully reduces to 5/11.
We can think of it like saying "There are 5 red marbles out of 11 total".
5/11 = 0.4545 = 45.45% approximately

Complete question
Mr porter had eight parties at her house last year the number of guests at each party is shown below 15,19,9,27,21,21,10,14. What is the median numbers of those parties
The median value is the value at the middle after rearrangement
On rearranging in ascending order
9, 10, 14, (15, 19), 21, 21, 27
Since there are two values in the middle, we will take the average of the numbers
Median = 15+19/2
Median = 34/2
Median = 17
Hence the median value is 17
???????????????….?????…..?????????
Answers
Answer:
C
Step-by-step explanation:
Sine equals opposite over hypotenuse, which would be y/19. To find y multiply by 19 to get y=19sin33°
The values given are 19 (hypotenuse), y (adjacent side), and the angle (33°)
The formula for cosine is adjacent side divided by the hypotenuse
After plugging in the values given into the formula cosx=ad/h, we have:
Cos33°=y/19 Here, we need to isolate the Y
And, the final result is
19Cos33°= Y
So, the correct answer is the letter D
