Answer:
145.83 kilómetros.
Step-by-step explanation:
Si un conductor llena su tanque con $600 y recorre 250 kilómetros, para determinar cuántos kilómetros podrá recorrer con $350 de combustible se debe realizar el siguiente cálculo:
600 = 250
350 = X
350 x 250 / 600 = X
87,500 / 600 = X
145.83 = X
Así, con $350 de combustible se podrán recorrer 145.83 kilómetros.
Answer:
Probability that at most 50 seals were observed during a randomly chosen survey is 0.0516.
Step-by-step explanation:
We are given that Scientists conducted aerial surveys of a seal sanctuary and recorded the number x of seals they observed during each survey.
The numbers of seals observed were normally distributed with a mean of 73 seals and a standard deviation of 14.1 seals.
Let X = <u><em>numbers of seals observed</em></u>
The z score probability distribution for normal distribution is given by;
Z =
~ N(0,1)
where,
= population mean numbers of seals = 73
= standard deviation = 14.1
Now, the probability that at most 50 seals were observed during a randomly chosen survey is given by = P(X
50 seals)
P(X
50) = P(
) = P(Z
-1.63) = 1 - P(Z < 1.63)
= 1 - 0.94845 = <u>0.0516</u>
The above probability is calculated by looking at the value of x = 1.63 in the z table which has an area of 0.94845.
Answer:
B. 548926
Step-by-step explanation:
Given
SYSTEM => '131625', and KARMA => '94854'
Required
MARKET is coded as?
To solve this, we simply map out each letter to the given characters;
This is done as follows:
S-> 1
Y-> 3
S-> 1
T-> 6
E -> 2
M-> 5
K-> 9
A-> 4
R-> 8
M-> 5
A -> 4
Remove repetitions
S-> 1
Y-> 3
T-> 6
E -> 2
M-> 5
K-> 9
R-> 8
A -> 4
Now, we can code MARKET using the same system
M-> 5
A -> 4
R-> 8
K-> 9
E -> 2
T-> 6
MARKET => 548926
This is sort of weird to write without any numbers, but it's not too hard. take your info out of the word problem:
fit fast = fee per class
stepping up = fee per class + monthly fee
now you just change all of that into variables, essentially:
F = cx
S = cx + m
so, fit fast is the cost of classes (c) times the number of classes taken (x). stepping up is the cost of classes times x, PLUS that additional monthly fee (m).
