Answer:
The proportion of scores reported as 1600 is 0.0032
Step-by-step explanation:
Let X be the score for 1 random person in SAT combining maths and reading. X has distribution approximately N(μ = 1011,σ = 216).
In order to make computations, we standarize X to obtain a random variable W with distribution approximately N(0,1)
The values of the cummulative distribution function of the standard Normal random variable, lets denote it are tabulated, you can find those values in the attached file. Now, we are ready to compute the probability of X being bigger than 1600
Hence, the proportion of scores reported as 1600 is 0.0032.
Answer:
268.8 rounds to 270
Step-by-step explanation:
to change percent into decimal move the decimal 2 places to the left. than multiply it by 960
Answer:
Replace the variable x with −1
in the expression.
f(−1)=−(−1)²−1
Simplify −(−1)²−1.
Remove parentheses.
−(−1)²−1
Multiply −1 by (−1)²
by adding the exponents.
(−1)³−1
Raise −1 to the power of 3.
−1−1
Subtract 1 from −1.
−2
Step-by-step explanation:
Hope it's right
Each box contains 24 pens...and u need 266 pens..
266/24 = 11.08....u would need to buy 12 boxes.....because 11 boxes would only have (11 * 24) = 264 pens
answer : 12 boxes
