Hello there!
The correct answer is option B (-3,3)
-3x - y = 6
-3(-3) - 3 = 6
9 - 3 = 6
6 = 6
Thus, the correct answer is option B
Good luck with your studied!
Answer:
$3.55
Step-by-step explanation:
1st number after 0 is tenths, 2nd is hundredths.
since the number after is 5, we round up
When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17
Answer:
x=6
Step-by-step explanation:
Because these lines are parallel, that means these angles are congruent, so you can set up an equation because they are equal to each other.
110=19x-4
add 4 to both sides
114=19x
and divide by 19
6=x
or
x=6
Answer:
A. 0.0049
B. Yes
Step-by-step explanation:
Sample proportion = 0.64
N = 1000
Population proportion = 0.60
We solve for standard deviation
= √p(1-p)/n
= √0.60(1-0.60)/1000
= √0.60x0.40/1000
= √0.00024
= 0.0155
A.
The probability of sample >=0.64
Z>=0.64-0.60/0.0155
Z >= 0.04/0.0155
So z >= 2.5806
Using excel this equal to 0.0049
0.0049 is probability of sample proportion being 0.64 at least.
