Answer:
The slope of an equation perpendicular to this one would be 2/3.
Step-by-step explanation:
In order to find this, we need to first find the slope of this line. We do this by solving for y.
-2y = 3x + 7
y = -3/2x - 7/2
Now we know the slope is -3/2. In order to find the perpendicular slope, we first flip the equation. So -3/2 becomes -2/3. Then we change the sign. So -2/3 becomes 2/3. This will be the new slope.
Answer:
Complementary angle
Step-by-step explanation:
It adds up to 90 degrees
Answer:
D. x + 19
is the sum of 3(x + 3) and -2(x - 5).
Step-by-step explanation:
3(x + 3) + -2(x - 5)
= 3x + 9 + -2x + 10
= 3x + 9 - 2x + 10
= (3x - 2x) + (9 + 10)
= x + 19
Pythagoras; a^2 + b^2 = c^2 So, (6.7)^2 + (5.5)^2 = 75.14 then square root to get, 8.668 (to 3 d.p) hope this helps!!
Answer:
Null hypothesis:
Alternative hypothesis :
C. The mean Rutgers College GPA has increased to more than 3.15
Step-by-step explanation:
Data given and notation
represent the average score for Rutgers College in 2000
represent the average score for Rutgers College in 2002
represent the sample standard deviation in 2000
represent the sample standard deviation in 2002
sample size
State the null and alternative hypotheses. .
What are H0 and Ha for this study?
Null hypothesis:
Alternative hypothesis :
For this case we need to take in count that the alternative hypothesis can't have and = sign, and based on the information a good hypothesis here would be if the average GPA increased between 2000 and 2002, so based on this the best option for this case would be:
C. The mean Rutgers College GPA has increased to more than 3.15
