Answer:
D
Step-by-step explanation:
a^-b = 1/a^b
Using this formula...
10^-3 = 1/10^3
So this expression is basically saying...
1/1000 or 0.001
Answer:
y = -
x + 
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 )
Rearrange 4y = 5x + 3 into this form by dividing the 3 terms by 4
y =
x +
← in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (3, - 2) into the partial equation
- 2 = -
+ c ⇒ c = - 2 +
= 
y = -
x +
← equation of perpendicular line
The appropriate statistical test for whether the mean rating of guilts are greater for unattractive defendants than for attractive is:
B. 1 tailed t-test.
<h3>What are the hypothesis test?</h3>
At the null hypothesis, it is tested if the mean rating of guilt will not be higher for unattractive defendants than for attractive defendants, that is:

At the alternative hypothesis, it is tested if the rating is greater, that is:

We are comparing the means, hence a t-test is used. We are testing if one is greater than other(not different), hence a 1-tailed test is used, and option B is correct.

Answer:
The player's vertical jump ability is 15 inches
Step-by-step explanation:
The mark on the scale which the player's hand can reach while standing = 4-in which is the standing reach
The mark on the scale the player's hand can reach when jumping = 19-in
Therefore, the player's vertical jumping ability is given as the difference between the height the players hand can reach when jumping and the height which the player's hand can when standing,
Which gives;
The player's vertical jump ability = 19 inches - 4 inches = 15 inches
The player's vertical jump ability = 15 inches.
I thin the answer's B, 4/13
