<h3>
Two possible answers: 6 or -6</h3>
==========================================================
Explanation:
r = common ratio
To get any term in a geometric sequence, we multiply the previous term by r.
So that means 4r is the second term, since 4 is the first term.
The third term is (4r)*r = 4r^2, which is equal to 9 as given to us.
4r^2 = 9
4r^2 - 9 = 0
(2r)^2 - (3)^2 = 0
(2r - 3)(2r + 3) = 0 ... difference of squares rule
2r-3 = 0 or 2r+3 = 0
2r = 3 or 2r = -3
r = 3/2 or r = -3/2
r = 1.5 or r = -1.5
We can use each r value to find the possible second term
S = 4r = 4*(1.5) = 6
S = 4r = 4*(-1.5) = -6
The second term is either 6 or -6.
We could have this sequence: 4, 6, 9, ...
Or we could have this sequence: 4, -6, 9, ...
Answer: 0.345
Step-by-step explanation:
Given: The the setup for this hypothesis test:

Since , the alternative hypothesis is left tail , so the test is left tail test.

The test static for population proportion is given by :-

The p-value of z = 
Y=2/3x -4 . First, you look for the y when x=0. Then you try to find the best variation
Answer:
They have <u>18</u> vegetable plants.
Step-by-step explanation:
Given:
Emily's family loves to work together in the garden.
They have a. preference for flowers as 80% of their plants are flowers and the rest are vegetables.
They have 90 plants in the garden.
Now, to find the number of vegetable plants.
<u><em>Total plants in the garden = 90.</em></u>
80% of the plants are flowers.
So, number of plants which are flowers = 80% of 90.



<u><em>The number of flower plants = 72.</em></u>
Total plants = 90 (given)
So, to get the number of vegetable plants we subtract:

<u><em>Thus, vegetable plants = 18.</em></u>
Therefore, they have 18 vegetable plants.
Answer:
- ∠UTC = 55°
- ∠UCD = 70°
- ∠BCT = 55°
Step-by-step explanation:
In this figure of overlapping parallelograms, each angle is related to the others by several different theorems involving triangles, parallelograms, and parallel lines. That is, there are several different ways one can arrive at the answers to this question.
__
<h3>UTC</h3>
∠UTC ≅ ∠UDC = 180° -∠EDU . . . opposite angles of parallelogram; linear pair
∠UTC = 180° -125° = 55°
__
<h3>UCD</h3>
∠UCD ≅ ∠TBC = 180° -∠TBA . . . . corresponding angles; linear pair
∠UCD = 180° -110° = 70°
__
<h3>BCT</h3>
∠BCT ≅ ∠UTC = 55° . . . . alternate interior angles
