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:
Step-by-step explanation:
you started by expanding the bracket 3(2x+6) became 6x+18.\
Then you rearranged the equation so like terms were together.
You put brackets around the like terms so (27+18)+(6x+2x)
You added the first like terms (27+18)= 45
then you added the second like terms (6x+2x)= 8x
Answer:
- <u>0.5 s</u> (using 1 significan figure since the initial velocity is given with 1 significant figure)
Explanation:
Let's see what each term in the function v (t) = - 9.8t + 5 means:
The variable t is the time
The coffecient - 9.8 (which is negative) means that the velocity is reduced 9.8 m/s each second.
That means that the motion is uniformly decelerated with acceleration - 9.8 m/s².
The term + 5, means that the object was launched with an upward velocity of 5 m/s.
Hence the equation tells that after the object was launched upward it starts to lose speed and will reach a maximum height when the velocity is equal to zero, from which it starts falling.
So, you can calculate when the object reachs it maximum height and starts falling by making the velocity, v (t), equal to zero and solving for t. This is how you do it:
- v (t) = 0
- 0 = - 9.8t + 5
- 9.8t = 5 remember that the units of 9.8 is m/s² and of 5 is m/s
- t = 5 m/s / 9.8 m/s² = 0.51 s
So, the object starts fallin at 0.51 s. Since, the velocity is reported with 1 significant digit you answer should also show 1 significant digit, which means t = 0.5 s.

Step-by-step explanation:
Here you find the greatest common factor of 16,20 and 24
The greatest common factor of a set of whole numbers is the largest positive integer that divides evenly into all numbers with no remainder.
Here, the G.C.F will be
16 20 24
2 8 10 12
2 4 5 6
2×2=4
