Answer:
Let's see what to do buddy...
Step-by-step explanation:

STEP (1)
We have to know how many pets does the pet store have.
Look : 10 + 9 + 8 = 27
So the pet store completely have 27 pets.

STEP (2)
Mario randomly selects a pet :
Is the Probability of selecting a cat.
##############################
Is the Probability of selecting a dog.

STEP (3)
(( or )) in mathematics means plus (( + )) .
So the Probability of selecting a cat or a dog means :

Answer:
C, 360
Step-by-step explanation:
Interior angle sums can be found using the equation (N=-2)*180, where N equals the number of sides of the polygon.
Answer:
Step-by-step explanation:
If k is the number of classes and n is the number of observations, then for number of classes we should select the smallest k such that 2^k > n.
<u>We have n = 50 and:</u>
- 2^5 = 32 < 50
- 2^6 = 64 > 50
As per above described 2 to k rule, we are taking k = 6.
So 6 classes should be used.
Answer:
(x - 3) • (x^2 - 4x - 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-4x-7
The first term is, x2 its coefficient is 1 .
The middle term is, -4x its coefficient is -4 .
The last term, "the constant", is -7
Step-1 : Multiply the coefficient of the first term by the constant 1 • -7 = -7
Step-2 : Find two factors of -7 whose sum equals the coefficient of the middle term, which is -4 .
-7 + 1 = -6
-1 + 7 = 6
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
(x - 3) • (x2 - 4x - 7)

Answer:
15
Step-by-step explanation:
The pertinent general formula for this arithmetic progression is
a(n) = a(1) + d(n - 1), where d is the common difference. That difference is d = 4.
Here, a(n) = -5 + 4(n -1)
Therefore, a(6) = -5 + 4(5) = 15
