Answer:

C. 1/3

Step-by-step explanation:

Replace each letter with their corresponding value and simplify using the order of operations:

a(b - c*c)

turns into:

\frac{2}{3} (\frac{3}{4}-(\frac{1}{2}*\frac{1}{2}))

You want to remember that order of operations follows the rules of PEMDAS. The operations within the parentheses come first.

1/2 times 1/2 = 1/4

Now we have:

\frac{2}{3}(\frac{3}{4}-\frac{1}{4})

Then 3/4 - 1/4 = 2/4 = 1/2

\frac{2}{3}(\frac{1}{2}) = 1/3

Therefore your answer is C. 1/3

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em>a</em> = 2/3

<em>b</em> = 3/4

<em>c</em> = 1/2

a(b - c²)

<u>Step 2: Evaluate</u>

  1. Substitute in variables:                                                                                     2/3[3/4 - (1/2)²]
  2. [Brackets] Exponents:                                                                                      2/3(3/4 - 1/4)
  3. (Parenthesis) Subtract:                                                                                     2/3(1/2)
  4. Multiply:                                                                                                             1/3

Rob buy 6 tickets to the basketball game he pays $8.50 for parking. His total cost is $40.54. What is the cost of each ticket?
Natalija [7]
The cost of all the tickets is 32.04

Subtract $8.50 from $40.54 to leave you with the ticket costs. 

Each individual ticket would be 5.34. You get this because $32.04 divided by six tickets is the cost of one.

How to solve 2x-y=17;x-y=10
Nataliya [291]
The answer is that y is equal to -3 and x is equal to 7 
2x-y=17
-2(x-y)=10 )
--------------
2x-y=17
-2x+2y=-20
----------------
y=-3

x-y=10 
x-(-3)=10
x+3=10
 -3   -3
----------
x=7

For (5, -2): -2 - 4(5) = -2 - 20 = -22 ≤ -5         [false]
For (-2, 1): 1 - 4(-2) = 1 + 8 = 9 ≥ -5              [true]
For (-4, 2): 2 - 4(-4) = 2 + 16 = 18 ≥ -5          [true]
For (1, -1): -1 - 4(1) = -1 - 4 = -5 ≥ -5            [true]
For (4, 0): 0 - 4(4) = 0 - 16 = -16 ≤ -5            [false]

Therefore, options B, C, and D satisfy the inequality.

I will give BRAINLIEST! ANSWER QUESTION! I NEED IT ASAP
kykrilka [37]

The correct answer is  CI = (71.415%, 78.915%)

The correct option is (A)

<h3 /><h3>What is Confidence level?</h3>

A confidence interval is the mean of your estimate plus and minus the variation in that estimate.

Given:

x = 376

Sample = 500 students

CI= [(376/500-1.96 √((376/500)*(124/500)/500) , (376/500-1.96                

                                                                         √((376/500)*(124/500)/500)]

CI = (71.415%, 78.915%)

Hence, CI = (71.415%, 78.915%)
