Answer:
A
Step-by-step explanation:
trust me brother
subtracting a negative number is the same as adding the number
Answer:
The value is
Step-by-step explanation:
From the question we are told that
The probability of the device failing during the warranty period is 
The sample size is 
The random variable considered is x = 15
Generally this is distribution is binomial given the fact that there is only two out comes hence
X which is a variable representing a randomly selected selected electronic follows a binomial distribution i.e

Now the mean is mathematically evaluated as

=> 
=> 
The standard deviation is mathematically represented as

=> 
=> 
Now given that n is very large, then it mean that we can successfully apply normal approximation on this binomial distribution
So
Now applying Continuity Correction we have

Generally 

From the z-table

Thus
Answer:
4 [miles].
Step-by-step explanation:
1) the condition 'the entire trip took 5 hours' can be written as (where t_us - time spent upstream, t_ds - time spent downstream)

2) but the distance [D] upstream is equal the distance downstream, then the condition above can be written:

3) finally,

D=5*4/5=4 [miles].
Answer:
First, second, third, and fourth are functions
Step-by-step explanation:
Each input in the first, second, third, and fourth only have one output. In the fifth one 3.3 and 6.6 are seen twice as the x-value, so this is incorrect.
(answered this on your other question, but I will put it here too!)
Cada entrada en la primera, segunda, tercera y cuarta tiene solo una salida. En el quinto, 3.3 y 6.6 se ven dos veces como el valor de x, por lo que esto es incorrecto.
(respondí esto en tu otra pregunta, ¡pero también lo pondré aquí!)
Three- Fifth of m is equal to 15
Step-by-step explanation:
Step 1:
Here the expression given is
3/5 m = 15
Step 2:
To express the equation in terms of sentence,
THREE-FIFTH OF M IS EQUAL TO 15
