Answer:
$24
Step-by-step explanation:
Since 25% is off the price of the shirt, she bought the shirt at 75% of it's cost price. This difference between the full cost and the 75% is what she saved (i.e. 25% was the savings)
So, if the shirt costs x dollars:
$6 = 25% of x
= ( 25/100)*X = 0.25X
X = $6/0.25 = $6x4
X = $24
Given
mean=35 psi
std dev=2 psi
distribution normal
For probability that X<38,
calculate
Z score = (X-mean)/std dev
=(38-35)/2=1.5
P(X<38)
=P(Z<1.5)
=0.9331928 from tables.
So probability that the strength of a random sample <38 pis = 0.9332
Answer:
The first one, 2 square+ 3 squared= <em>d </em>squared
Step-by-step explanation:
The theory for finding the hypotenuse of a triangle is:
Okay, to start, we can multiply the $2 coupon by two because that is the amount of pairs she is going to by. So it would be $4 off. Now, if all of the shoes she purchased the same price, this is made a little easier. We can simply take $80 and $122 and add it by the $4 discount. Our new numbers would be $84 and $126. Now in order for this to work we would want all the numbers to be the same. We take $84 and divide it by three pairs, to get the values. For the least amount she can spend per pair is $28 and the most amount she can spend per pair is $42.
36*40+36*40-6*6=2844ft^2
we had to subtract the area of the closet so it wasn't counted twice :P
