Answer:
x = 4, ∠I = 33°
Step-by-step explanation:
<u>Question 1</u>
Converse to Base Angles Theorem: 28 = 9x - 8,
28 = 9x - 8 (add 8 to both sides)
9x = 36 (divide both sides by 9)
x = 4
<u>Question 2</u>
Since the triangles are congruent, ∠A ≅ ∠G:
∠A = 55 = ∠G
If we consider triangle ALX we have ∠L = 180-55-92 = 33°
And since ∠L ≅ ∠I, ∠I = 33° respectively
Yes she can because after estimating, the total amount the books weigh is ~5lbs
The random selection of a blue marble is an illustration of probability
You should expected to pull a blue marble 10 times
<h3>How to determine the expected blue marble?</h3>
The given parameters are:
Blue = 16
Red = 12
Green = 12
The total number of marbles is:
Total = 16 + 12 + 12
So we have:
Total = 40
The probability of selecting a blue marble is:

When 25 marbles are selected, the expected number of blue is:

So, we have:


Hence, the expected number of blue marbles is 10
