A very simple way to solve this specific problem is acknowledging the fact that the left hand side (L.H.S) is being multiplied by a factor of 10 to get the equation on the right hand side (R.H.S). So, if we multiply the denominator by 10, we'll get the answer, which would be 1 × 10 = 10 weeks.
Hope I could help! :)
The answer of number 10 is A.
Answer:
The values of a and b are -1.28 and 1.28 respectively.
Step-by-step explanation:
It is provided that the area of the standard normal distribution between a and b is 80%.
Also it is provided that a < b.
Let us suppose that a = -z and b = z.
Then the probability statement is
Simplify the probability statement as follows:
Use the standard normal distribution table to determine the value of <em>z</em>.
Then the value of <em>z</em> for probability 0.90 is 1.28.
Thus, the value of a and b are:
Thus, .
Answer:
y≤10
Step-by-step explanation:
Answer:
Simplifying the expression, the answer would be .
Process:
Basically, you just need to multiply the power on the outside with the powers on the inside of the parenthesis. Then, for the base take -3 to the fourth power which will lead you to your final answer .
