Note that 60 minutes is 1 standard deviation away from the mean and from recalling the 68-95-99.7 rule, the area that will remain is (100 - 68) = 32%. However, we only want the leftmost portion of this area, so the answer is 32%/2 = 16%.
<span>Choose D.</span>
<span>you can solve all quadratic equations using this method:
---
x^2 + 4x + 4 = 0
---
the above quadratic equation is in standard form, with a=1, b=4, and c=4
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 4 4
into this solver: https://sooeet.com/math/quadratic-equation-solver.php

this quadratic has ONE real root (the x-intercept), which is:
x = -2
x = -2

Answer:
the commutative property because you’re not changing the way its form style, but of more like their former
Answer:
The first table is the only table representing a linear function.
Step-by-step explanation:
<em>" You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear."</em>

Answer:
D) 44 inches
Step-by-step explanation:
Isosceles trapezoids have equal legs, which is why they are called isosceles.
Squares have equal side lengths are around, so you know that the missing side lengths to this figure are 5 in, 10 in, and 10 inches.
Add all of the given values together.
Add all of the "unknown" values together.
- 5 in + 10 in + 10 in = 25
Add these two values together.
- 19 in + 25 in = 44 inches
This answer corresponds to answer choice D.
