∠6 is vertical to ∠5 and ∠7 is vertical to ∠8. If ∠6=∠7 then ∠5=∠8
Well, the first thing we need to do is divide 10 by 4. These teo numbers are the number of pens, and cost of them. So,
================================
10 / 4 = 2.5
--------------------------------------------------------
Now we have to use the answer we got, 2.5 which is the cost of 1 pen, and multiply it by 7.
================================
2.5 x 7 = 17.5
--------------------------------------------------------
This means that 7 pens cost <span>£</span>17.5
For number 16
2x+6+x=180
3x+6=180
3x=180-6
3x=174
x=58
2(58)+6 =122
Linear pairs are 180 degree angles
Angle 1 = 58
Angle 2 = 122
Answer:
(C) 350 yards
Step-by-step explanation:
From available information
Mean = 790
1 running back = 1637 yards
Standard deviation above mean = 2.42
Using formula
z =( x - mean)/sd
2.42 = (1637-790)/sd
2.42 = 847/sd
We cross multiply
2.42sd = 847
Divide through by 2.42
Sd = 847/2.42
Sd = standard deviation = 350
So our answer is 350 and therefore option c.
