Answer:
original price = 260
Step-by-step explanation:
original price * percent off = discount
then subtract the discount
original price - discount = new price
so
original price - original price * percent off = new price
factor out the original price
original price( 1- percent off) = new price
original price = new price/ ( 1- percent off)
lets put in what we know
original price = 182/(1-.30)
original price = 182/(.7)
original price = 260
Answer:
Step-by-step explanation:
Factorize the denominator
Sum = 4
Product = 3
Factors = 1 , 3 {1*3 = 3 and 1+3 = 4}
x² + 4x + 3 = <u>x² + x</u> + <u>3x + 1*3</u>
= x(x + 1) + 3(x + 1)
= (x + 1)(x + 3)
GCF of the numerator and denominator = (x + 3)
Answer:
Step-by-step explanation:
Domain x^2 - 9 {Solution: - infinity < x < infinity}
Interval notation (- infinity, infinity)
Range of x^2 - 9 (Solution: f(x) is greater than or equal to - 9)
Interval notation (-9, infinity)
Axis interception points of x^2 - 9:
X- intercepts (3, 0) (-3, 0)
Y-intercepts (0, -9)
Vertex of x^2 - 9: Minimum (0, -9)
Solve for f:
f (x) = x^2 - 9
Step 1: Divide both sides by x.
fx / x = x^2 - 9 / x
f = x^2 - 9 / x
Answer:
f = x^2 - 9 / x
First, we find how much 1 baseballs card costs.
1 card = 0.60
12*0.6 = $7.20
Answer: 95.45 %
Step-by-step explanation:
Given : The distribution is bell shaped , then the distribution must be normal distribution.
Mean : 
Standard deviation :
The formula to calculate the z-score :-
For x = 13
For x = 19
The p-value = 
In percent, 
Hence, the percentage of data lie between 13 and 19 = 95.45 %
