2.1 + (–3.4 + 5) = [ + (–3.4)] + 5 = false
2.1 + (–3.4 + 5) = 3.7
[ + (–3.4)] + 5 = 1.4
Thus your answer is 2.1

Answer:
<em>First option 5%</em>
Step-by-step explanation:
<u>Normal Distribution</u>
Gauss Distribution is one of the most widely-used continuous probability distribution to characterize random events. The curve of the function is called the bell curve.
The standard Normal Distribution is a special case where the mean and the standard deviation . The values of the cumulative normal distribution cannot be computed by simple calculations, we must use tables of digital implementations integrated with tools like Excel or any online resource.
The entry for standard normal distribution is a parameter called the z-score, computed like shown below
The values provided in our problem are
Computing z results
By using any of the aforementioned resources, we compute the left-tail probability
We choose the first option 5%
60 minutes = 1 hour<span>12 inches x 60 minutes = 720 inches per hour
</span><span>12 inches = 1 ft</span><span>720 inches per hour / 12 = 60 ft per hour</span> Tortoise B is faster.
Answer:
151
Step-by-step explanation:
Let x = the smaller integer and y = the larger integer.
We have two conditions:
(1) x + 1 = y
(2) y = 2x - 149 Substitute (1) into (2)
x + 1 = 2x - 149 Add 150 to each side
x + 150 = 2x Subtract x from each side
x = 150 Substitute into (1)
150 +1 = y
y = 151
The larger integer is 151.
<em>Check:
</em>
(1) 150 + 1 = 151
151 = 151
(2) 151 = 2×150 -149
151 = 300 -149
151 = 151
