It's kinda hard because there is no z table available, but we can estimate around 1.64
p[95] = 664.4853
either 660 or 670
1.64 (100) = 164 + 500 = 664
i'd say that if you're within the p[95] the Score wil be 660
Hope this helps
Answer:
13
Step-by-step explanation:
x/y = 4
x=4y
x - y = 39
4y - y = 39
3y = 39
y= 13
Answer:
Step-by-step explanation:
Given
See attachment for triangle
Required
Calculate
First, we add up the angles in the triangle;
Collect like terms
Solve for x
Given that:
Answer:
AB = b - a
Step-by-step explanation:
AB = -OA + OB
AB = -a + b we usually write the positive vector first
AB = b - a
We know that P divides AB in the ratio 3:1 so PB = 1/4 AB
AB is negative as we are going in the opposite direction
OP = OB - 1/4 AB
OP = b - 1/4 (b - a)
multiplying inside the brackets:
OP = b - 1/4b + 1/4a
OP = 3/4b + 1/4a
B=-6 is the correct answer
