Answer:
the trapiezium
Step-by-step explanation:
It has a area of 4 which is the highest
Answer:
C
Step-by-step explanation:
The angle between the tangent and the radius at the point of contact is right.
Thus the triangle is right with hypotenuse = 3 + 8 = 11 ( 3 is the radius )
Using Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 3² = 11², that is
x² + 9 = 121 ( subtract 9 from both sides )
x² = 112 ( take the square root of both sides )
x = = = × = 4 → C
Answer:
blue
Step-by-step explanation:
Its blue because if purple has 2 and blue has 1 then its blue which you are most likely to pick purple then blue
First you would distribute through the parenthesis
-10x+2+7(5x-1)-3(-5x+1)
Then distribute
-10x+2+35x-7-3(-5x+1)
And then distribute 3
-10x+2+35x-7+15x-3
Collect like terms
40x+2-7-3
40x-8 is your answer :)
Answer:
a) The null and alternative hypothesis are:
b) Yes.
Step-by-step explanation:
This is a hypothesis test for the difference between proportions.
The claim is that the proportion of all NYC residents that can name a player on the Knicks differs from the proportion of all Toronto residents who can name a player on the Raptors.
As the claim is that the proportions differs, the difference to reject the null hypothesis can be positive or negative. Then, this is a two-tailed test.
The null and alternative hypothesis are:
The conditions to met for this test are:
- The sampling method for each population is simple random sampling.
- The samples are independent.
- Each sample includes at least 10 successes and 10 failures.
- Each population is at least 20 times as big as its sample.
This conditions are met, so all criteria for the hypothesis test is satisfied.
