The probability is 0.7734.
The z-score for this value is given by:
z =(X-μ)/σ = (83-101)/24 = -18/24 = -0.75.
Using a z-table (http://www.z-table.com) we see that the area to the left of this (lower than) is 0.2266. We want the percentage that will score higher on the test, so we subtract fro 1:
1 - 0.2266 = 0.7734.
Answer:
The absolute value of 23 is 23, im
pretty sure
Answer:
3x²-10x+8
Step-by-step explanation:
To simplify the expression we need to multiply each term in the first bracket with the expression in the second bracket.
x(3x-4)-2(3x-4)
3x²-4x-6x+8
Executing the operations to give a quadratic expression we get:
3x²-10x+8
The simplified expression is therefore
3x²-10x+8
Answer:
Step-by-step explanation:
we know that
The formula to solve a quadratic equation of the form
is equal to
in this problem we have
equate to zero
so
substitute in the formula
therefore
StartFraction 2 Over 11 EndFraction plus-or-minus StartFraction StartRoot 15 EndRoot Over 11 EndFraction
The answers are
a) the domain is all real numbers
d) the input to an exponential function is the exponent
e) the base represents the multiplicative rate of change
hope this helps :)
