But where....is the histogram?
Answer:
A. Probability = 0.02
B. This is in a cumulative frequency table in the attachment I added
Step-by-step explanation:
A. We have these following probabilities
Prob(X=0) = 0.05
Prob(x= 2) = 0.30
Prob(X = 4) = 0.50
Prob(X < 2) = Prob(X=0) + prob(X=1)
0.18 = 0.05 + prob(X=1)
prob(X=1) = 0.13
A. Prob(x = 3)
= 1 - (0.05 + 0.13 + 0.30 + 0.50)
= 0.02
Probability of buying only 3 times = 2%
B. The cumulative frequency is in the attachment.
Answer:
x = (180 - 68) / 2
Step-by-step explanation:
x = 56°
Hey there!!
Let's write $1.5 as 15 / 10
15/10 = 3/2
$3/2
October price = $3/2
Let's take September price as ' x '
If we take a look at the question, we know
October price = 20% of September + September price
20% = 20/100 = 1/5
Of = multiplication
Plug in the values
3/2 = x/5 + x
LCM = 5
3/2 = 6x / 5
Multiplying by 5 on both sides
15/2 = 6x
Dividing by 6 on both sides
15/2 / ( 6 ) = x
15/2 × 1/6 = x
15/12 = x
15/12 = $1.25
The price in September = $1.25
Hope my answer helps!
