Answer:
![p = \frac{1564}{5020} = 0.3116](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B1564%7D%7B5020%7D%20%3D%200.3116)
Step-by-step explanation:
The point estimate for the population proportion is the number of sucesses divided by the size of the sample.
In this problem, we have that:
A success is being a tradition hogan in the reservation(the population). In a sample of 5020, 1564 are traditional hogans.
So ![p = \frac{1564}{5020} = 0.3116](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7B1564%7D%7B5020%7D%20%3D%200.3116)
Answer:
Step-by-step explanation:
h/w=9/16
h/42=9/16
h=42(9)/16
h=23.625
It will be 3/8 in less than 24 in, but 24 was a good guess. :)
If the negative exp is in the numerator put it in the denominator and make it positive. if it's already in the denominator move it to the numerator and make it positive
examples. x^-3 = 1/x^+3
a/(c*b^-2 ) = ab²/c
hope that helps!
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
+
= 1 ( multiply through by 2 to clear the fractions )
x + y = 2 ( subtract x from both sides )
y = - x + 2 ← in slope- intercept form
(a) with slope m = - 1
(b) with y- intercept c = 2
(c)
Parallel lines have equal slopes, thus
y = - x + c ← is the partial equation of PQ
To find c substitute (2, - 8) into the partial equation
- 8 = - 2 + c ⇒ c = - 8 + 2 = - 6
y = - x - 6 ← equation of PQ
To show (- 1, - 5) lies on PQ, substitute x = - 1 into the equation and evaluate for y.
y = - (- 1) - 6 = 1 - 6 = - 5 ← the given y- coordinate
Thus PQ passes through (- 1, - 5 )
