distributive property: $a(x+y+z)=a(x)+a(y)+a(z)[tex]-9(y-w+6)=-9(y)+(-9)(-w)+(-9)(6)=-9y+9w-54$ [/tex]
therefore

Women athletes at the university of colorado, boulder, have a long-term graduation rate of 67% (source: the chronicle of higher

Elodia [21]

The solution would be like this for this specific problem:

H0: p = p0, or 
H0: p ≥ p0, or
H0: p ≤ p0

find the test statistic z = (pHat - p0) / sqrt(p0 * (1-p0) / n)

where pHat = X / n

The p-value of the test is the area under the normal curve that is in agreement with the alternate hypothesis. 
H1: p ≠ p0; p-value is the area in the tails greater than |z|
H1: p < p0; p-value is the area to the left of z
H1: p > p0; p-value is the area to the right of z

Hypothesis equation:

H0: p ≥ 0.67 vs. H1: p < 0.67

The test statistic is: 
z = ( 0.5526316 - 0.67 ) / ( √ ( 0.67 * (1 - 0.67 ) / 38 )
z = -1.538681

The p-value = P( Z < z ) 
= P( Z < -1.538681 )
= 0.0619

Instructions: Given the following image of two parallel lines cut by a transversal, find the value of x.

mash [69]

Answer:

First, these angles are alternate interior angles.

$10x - 5 = 9x + 1$

$x = 6$

Step-by-step explanation:

(10x - 5)° and (9x + 1)° are alternate interior angles. Thus, they are congruent to each other.

Thus, to find x, we will set each angle equal to the other.

$10x - 5 = 9x + 1$

Solve for x. Collect like terms

$10x - 9x = 5 + 1$

$x = 6$

(a/5) - (b/3) = (a/2) - (b/6), solve for a

Gnom [1K]

Answer:

$a = - \frac{10}{17} b$

Step-by-step explanation:

(a/5) - (b/3) = (a/2) - (b/6)

+(B/3) + (b/3)

NOTE: use property of equality to isolate b from a

(a/5) = (b/3) + (a/2) - (b/6)

-(a/2) - (a/2)

NOTE: continue to use property of equality to isolate a from b

(a/5) - (a/2) = (b/3) - (b/6)

60((a/5) - (a/2)) = ((b/3) - (b/6))60

NOTE: 60 is a common multiple of 5, 2, 3, and 6

12a - 30a = 20b - 10b

NOTE: combine alike terms

-17a = 10b

-17a/-17 = 10b/-17

NOTE: decide by -16 to find what a is equal to

$a = - \frac{10}{17} b$
