Good evening.
This is a
incomplete quadratic equation, because it does not have the term
bx. Therefore, we can solve this faster with the following strategy:
Add
16 to both sides:
Take the square root:
Therefore:
Answer:
(4,3)
the distance between x1 and x2 then y1 then y2
Answer:
Test statistic, (to 3 dp)
Step-by-step explanation:
Deviation, d = x -y
Sample mean for the deviation
Standard deviation:
SD =2.93
Under the null hypothesis, the formula for the test statistics will be given by:
Answer:
90°
Step-by-step explanation:
ABC ~ DEF so that means E = B. A triangle has to add up to 180° so that means 180-35-55=90
