-------------------------------------------
Answer:
w ≤ -2
Step-by-step explanation:
The first point is on -2 and is going down the number line so w is less than -2 but since there is a closed circle, it would be w is less than or equal to -2 or w ≤ -2
Answer:B
Step-by-step explanation:
y - 26 = -19
y + 26 - 26 = -19 + 26
y=7
Answer:
Brand D has the highest return rate so they should eliminate that one.
Step-by-step explanation:
brand A - .0481
brand B - .0307
Brand C - .0410
Brand D - .0788
Answer:
167/346 or 0.483
Step-by-step explanation:
From the question given above, the following data were obtained:
Number of Tails (T) = 167
Number of Heads (H) = 179
Probability of tail, P(T) =?
Next, we shall determine total outcome. This can be obtained as follow:
Number of Tails (T) = 167
Number of Heads (H) = 179
Total outcome (S) =?
S = T + H
S = 167 + 179
Total outcome (S) = 346
Finally, we shall determine the probability of tails. This can be obtained as follow:
Number of Tails (T) = 167
Total outcome (S) = 346
Probability of tail, P(T) =?
P(T) = T / S
P(T) = 167 / 346
P(T) = 0.483
Thus, the probability of tails is 167/346 or 0.483
