Answer: 4 buses & 6 vans
Step-by-step explanation:
You have 4 buses so you would multiply 4 by 55 because each bus holds 55 students. Since you have 4 buses, you would have 6 vans because there is a total of 10 vehicles. Therefore, you would also multiply 6 by 11 because each van holds 11 students.
286 (students) = (6 x 11) + (4 x 55)
286 = 66 + 220
Answer:
Answer is 1/2
I clearly didn't understand the question u said it should be 5/2 or 2/5 or in fractional form
Take 12 from 24 and if the the answer is 12 then it's a factor.
Answer:
2.0
Step-by-step explanation:
Tangent is calculated as the length of the opposite side of an angle divided by the adjacent side of that angle.
The opposite of theta is 4, while its adjacent side is 2
tan theta = 4/2 = 2
Answer:
0.2207
Step-by-step explanation:
Here, we want to find the probability that the sample mean is greater than 25.
What we use here is the z-scores statistic
Mathematically;
z-score = (x-mean)/SD/√n
From the question;
x = 65, mean = 63, SD = 13 and n = 25
Plugging these values in the z-score equation, we have
Z-score = (65-63)/13/√25 = 2/13/5 = 0.77
So the probability we want to calculate is ;
P(z > 0.77)
This can be obtained from the standard normal distribution table
Thus;
P(z > 0.77) = 0.22065 which is 0.2207 to 4 d.p
