27^(4/3)+4^(3/2) can be simplified using roots.
The cube root of 27 is 3 and the square root of 4 is 2. This removes the denominators from the expression. The expression is now 3^4+2^3.
Simplify this and you get 81+8=89
Your answer is A. -56

Price before tax = $18
Tax = 7% x $18 = 0.07 x 18 = $1.26
Price after tax = $18 + $1.26 = $19.26
Answer: $19.26
If z represents the variable of the standard normal distribution curve N(0,1), which is symmetrical about z=0, then we look for
P(z)-P(-z)=0.9642=1-2P(-z) => P(-z)=(1-0.9642)/2=0.0179
=>
-z=-2.099192
=> z=2.099192
Check:
P(2.099192)-P(-2.099192)=0.9642 ok
Answer:
Z=-3 or Z=11
Step-by-step explanation:
we know that
The distance between point Y and point Z is 7 units
The point Y is located on the number line at 4
we have two possibilities
The point Z could be located to the right of point Y
The point Z could be located to the left of point Y
so
Z is either 7 units to the left of 4 or 7 units to the right of 4
<em>First case</em>
point Z to the right of point Y
To find out the coordinate of point Z sum the distance YZ to the coordinate of point Y
so
(4+7)=11
therefore
The first possibility is
Point Z is located at 11
<em>Second case</em>
point Z to the left of point Y
To find out the coordinate of point Z subtract the distance YZ from the coordinate of point Y
so
(4-7)=-3
therefore
The second possibility is
Point Z is located at -3
therefore
Z=-3 or Z=11
