Alright, lets get started.
We have given the ratio 9:45
or
could be written as
Means the given ratio is 1:5.
Means every given number should be in this ratio 1:5.
? : 30 means
Cross multiplying
Hence x = 6
For 7 : ?
Cross multiplying
x = 35
For 8 : ?
Cross multiplying
x = 40
Hence the answers are 6 30, 7 35, 8 40. : Answer
Hope it will help :)
Answer:
Step-by-step explanation:
Matt thinks that he has a special relationship with the number 2. In particular, Matt thinks that he would roll a 2 with a fair 6-sided die more often than you'd expect by chance alone. Suppose p is the true proportion of the time Matt will roll a 2.
(a) State the null and alternative hypotheses for testing Matt's claim. (Type the symbol "p" for the population proportion, whichever symbols you need of "<", ">", "=", "not =" and express any values as a fraction e.g. p = 1/3)
H0 =
Ha =
(b) Now suppose Matt makes n = 46 rolls, and a 2 comes up 10 times out of the 46 rolls. Determine the P-value of the test:
P-value = ( u figure it out) u got it
Answer:
900
Step-by-step explanation:
(n – 2)180 where n is the number of sides
since this is a 7 sided polygon
(7-2) * 180
5 * 180
900
Solve:
(3x-2)^2-4x(2x-3)>=0
(3x-2)(3x-2)-8x^2+12x>=0
9x^2-12x+4-8x^2+12x>=0
The solution: x^2+4>=0
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
