Solving the questions below we use PEMDAS
that is:
parenthesis, exponential, multiplication, division, addition then lastly subtraction.
1) 12×43+43×88
In this situation we begin by multiplication first:
516+3784
Next we add the result
4300

2)23×77+77×77
we multiply first
1771+5929
next we add them
7700

3) <span>3) 45∙123−45∙80+45∙57
We multiply first 
5535-3600+2565
next we add the positive numbers then lastly we subtract the results
8100-3600
subtracting gives us:
4500

4)</span><span>1341</span>×<span>12−12</span>×<span>1241
First we multiply the numbers
16092-14892
next we subtract:
1200</span>

Which represents the inverse of the function f(x) = 4x?
wel
The inverse of the funtion <span> f(x) = 4x

</span><span> f(x) = 4x
y = 4x
Swap out x with y
x = 4y
x / 4 = y
y = x / 4
f(x)^{-1} = \frac{x}{4}

Looks like none of the answer you have given are correct.

Use the data in the following​ table, which lists​ drive-thru order accuracy at popular fast food chains. Assume that orders are
Sergeu [11.5K]

Probability of getting an order from Restaurant A or an order that is accurate is 1.21,

The events are not disjoint events.

<h3>What is the probability?</h3>

Probability is used to calculate the odds that a random event would occur. The odds that the random event happens lie between 0 and 1.  

Total number of accurate orders = 332 + 277 + 244 +  150 = 1,003

Total number of orders = 31 + 51 + 30 + 10 + 1003 = 1,125

Total number of orders from restaurant A = 332 + 31 = 363

Probability of getting an order from Restaurant A = total number of orders from restaurant A / total number of orders

363 / 1125 = 0.32

Probability that the order is accurate = number of accurate orders / total number of orders

1003 / 1125 = 0.89

Probability of getting an order from Restaurant A or an order that is accurate = 0.32 + 0.89 = 1.21

Disjoint events are events that are mutually exclusive. If one event happens, the other event cannot happen
