Answer:

h =  - 12

Step-by-step explanation:

1) Add 1 to both sides.

\frac{h}{6}  =  - 3 + 1

2) Simplify -3 + 1 to -2.

\frac{h}{6}  =  - 2

3) Multiply both sides by 6.

h =  - 2 \times 6

4) Simplify 2 × 6 to 12.

h =  - 12

Answer:

h = - 12

Step-by-step explanation:

<u>Add </u><u>1</u><u> to both sides of the equation</u>

ℎ/6 − 1 + 1 = − 3 + 1

<u>Simplify</u>

ℎ/6 = − 3 + 1

h/6 = -2

<u>Multiply all terms by the same value to eliminate fraction denominators</u>

6 ⋅ ℎ/6 = 6 ( − 2 )

<u>Cancel multiplied terms that are in the denominator</u>

ℎ = 6 ( − 2 )

<u>Multiply the numbers</u>

ℎ = − 12

Complete the pairs of corresponding parts if ABD congruent to EFC.
Alchen [17]
Remember the notation..

When you have a triangle called ABD, the angles may be called in theses equivalent ways>

angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA

Then given that the two triangles are congruent, you can say an

angle B = angle F = ∠ EFC

So the answer is the last option of the list.

g in october 2012, apple introduced a much smaller version of the apple ipad, known as the ipad mini. weighing less than 11 ounc
atroni [7]

Using the concepts of probability, we got that 0.4286 is the probability  that the battery life for an iPad Mini will be 10 hours or less  which is about 42.86%.

From the given information;

Let  X represent the continuous random variable with uniform distribution U (A, B) . Therefore the probability density function can now be determined as :

f_X(x) = \frac{1}{B-A} where A<x<B

where A and B  are the two parameters of the uniform distribution

From the question;

Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours

So; Let A = 8,5 and B = 12

Therefore; the mathematical expression for the probability density function of battery life is :

f_X(x) = [1 / (12-8.5)]8.5<x<12

f_X(x)=(1/3.5)8.5<x<12

The  probability that the battery life for an iPad Mini will be 10 hours or less can be calculated as:

F(x) = P(X ≤x)

F(10)=(x-A)/(B-A)

F(10)=(10-8.5)/(12-8.5)

F(10)=1.5/3.5

F(10)=0.4286

Hence, the probability that the battery life for an iPad Mini will be 10 hours or less is 0.4286

(Complete question)

In October of 2012, Apple introduced a much smaller variant of the Apple iPad, known at the iPad Mini. Weighing less than 11 ounces, it was about 50% lighter than the standard iPad. Battery tests for the iPad Mini showed a mean life of 10.25 hours (The Wall Street Journal, October 31, 2012). Assume that battery life of the iPad Mini is uniformly distributed between 8.5 and 12 hours. What is the probability that the battery life for an iPad Mini will be 10 hours or less (to 4 decimals)?
