Answer:
And tha's equivalent to use this formula:
Step-by-step explanation:
For this case the 95%of the values are between the following two values:
(75 , 163)
And for this case we know that the variable of interest X "length of a movie" follows a normal distribution:
We can estimate the true mean with the following formula:
Now we know that in the normal standard distribution we know that we have 95% of the values between 1.96 deviations from the mean. We can find the value of the deviation with this formula:
And tha's equivalent to use this formula:
Answer:
Step-by-step explanation:
Given
Required
Cost of c cheese and f topping pizza
Solving for c cheese pizza
If 1 cheese pizza costs $6,
c cheese pizza would cost $6 * c
Solving for f topping pizza
If 1 topping pizza costs $10,
f topping pizza would cost $10 * f
Hence:
<em>Hence, the total amount paid is: </em>
<em></em>
Answer:
(-5,3)
Step-by-step explanation:
When you reflect over the x axis the numbers will be the same but the sign will change depending on which quadrant you end up in.
(5,3) will reflect over x axis and become (-5,3) and will be in the 2nd quadrant after reflecting.
Probability(error in one block)= 1/5
<span>Probability(error in 3 blocks)= 3*(1/5)= 0.6</span>
Let,
0 = No error
<span> 1 = error
</span>Hence.
E(x) = 0.4 x 0 x+0.6 + 1
= 1.6
