Answer:
D
Step-by-step explanation:
p +/- [z + sqrt(pq/n)]
0.65 + [1.645 × sqrt[0.65 × (1-0.65) ÷ 50]
0.65 +/- 0 1109613165
[0.5390386835 , 0.7609613165]
Answer:
The top graph on the right that is shaped like an M. :)
Let, x be the maximum hours he can rent skate board and helmet.
So, total price :
T = 4x + 6x
Now, it is given that he has only $30.
Therefore,
Total price should be less than or equal to $30.
4x + 6x ≤ 30
10x ≤ 30
x ≤ 3
Therefore, the maximum number of hours he can rent the skateboard is 3 hours.
Hence, this is the required solution.
Answer:
u = -3
Step-by-step explanation:
Step 1: Write equation
-4 + 2u = -10
Step 2: Solve for <em>u</em>
<u>Add 4 to both sides:</u> 2u = -6
<u>Divide both sides by 2:</u> u = -3
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 + 2(-3) = -10
-4 - 6 = -10
-10 = -10
3x-2=4
So x equals 2
3x2-2=4
3 times 2 is six and six minus two is 4
