A trapezoid is isosceles if and only if
(1) The base angles are congruent
(2) The diagonals are congruent
(3) The opposite angles are supplementary
So the description does not guarantee that a trapezoid is isoceles for "Congruent bases".
Answer:
0.1151
Step-by-step explanation:
Given that a laptop company claims up to 10.1 hours of wireless web usage for its newest laptop battery life. However, reviews on this laptop shows many complaints about low battery life. A survey on battery life reported by customers shows that it follows a normal distribution with mean 9.5 hours and standard deviation 30 minutes.
If X is the battery life then X is N(9.5, 0.5)
(we convert into one unit for calculations purpose here hours)
a) the probability that the battery life is at least 10.1 hours
=
we get the probability that the battery life is at least 10.1 hours is 0.1151
Answer:
B.
Step-by-step explanation:
For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.
$25a + $15s =$305
a + s = 17
a = 17 - s
$25a +$15s =$305
$25(17-s) + $15s=$305
425-25s +15s = $305
425-10s=305
-10s=305-425
-10s= -120
-10s/-10 = -120/-10
s = 12
a+ 12 = 17
a = 5
Check
$25a + $15s =$305
$25(5) + $15(12) =$305
125 + 180 = 305
305 = 305
Answer:
The growth rate of Plant A is not proportional
because the line is not straight.
The growth rate of Plant B is proportional
because when the data is graphed on the
coordinate plane, the line formed is a straight
line that passes through the origin.
