I’m pretty sure it’s 370 bc
1 and a half hours is 80+40 (40 is half of 80)
and 2 and a half hours, so 100 for each hour.
100+100+50= 250
250+120=370!!
answer : 370 kilometers per hour
Answer:
The number is 133.5
Step-by-step explanation:
Let the number = x
2/3 * x = 89 Multiply by 3
2x = 89 * 3 Combine
2x = 267 Divide by 2
x = 133.5
Since the triangles make up a spinner, the triangles are isosceles.
The base is 2 cm and the perimeter is 10 cm.
The measure of the two legs can be determined from
2 + 2x = 10
Where is the length of the leg
Solving for x
x = 4
The area an isosceles is calculated using
where b is the length of the base
Substitute the values and multiply with the number of triangles in the spinner
Answer:
The probability of passing the course given that the course taken was statistics = P(pass|C) = 0.7414
Step-by-step explanation:
This is a combined probability question
PASS FAIL Withdrew TOTAL
(C) .238 .044 .039 .321
(S) .559 .051 .069 .679
(T) .797 .095 .108 1
C represents probability data from Calculus exam and S represents probability data from Statistics exam
Compute the probability of passing the course given that the course taken was statistics = P(pass|C)
Mathematically, this is given by
P(pass|C) = P(pass n C)/P(C)
Probability of passing Calculus, P(pass n C) = 0.238 (from the table)
Probability of offering Calculus, P(C) = 0.321 (from the table)
the probability of passing the course given that the course taken was statistics is P(pass|C)
P(pass|C) = 0.238/0.321 = 0.7414
Answer:
0.018133
Step-by-step explanation:
Given that customers arrive randomly and independently at a service window, and the time between arrivals has an exponential distribution with a mean of 12 minutes.
Let X equal the number of arrivals per hour.
X is having average as reciprocal of 12 minutes
i.e. in one hour on an average expected customers to arrive is 60/12 =5
X being reciprocal of exponential is Poisson with parameter = 5
Probability that 10 customers arrive in one hour
=P(X=10)
=0.018133
