Answer:
7 and 3 respectively
Step-by-step explanation:
Peanuts (p/lb) = $1.80
Cashews (p/lb) = $4.50
Total pound = 10 pounds
Aggregate amount (at $2.61 per lb) = $26.1
Pound of peanut to buy = x
Pound of cashew to buy = y
x + y = 10..........(i)
1.8x + 4.5y = 26.1.....(ii)
Multiply equ (i) by 1.8 and equ (ii) by 1
1.8x + 1.8y = 18
1.8x + 4.5y = 26.1
Subtract (i) from (ii)
4.5y - 1.8y = 26.1 - 18
2.7y = 8.1
y = 3
Sub y = 3 into (i)
x + y = 10
x + 3 = 10
x = 10 - 3
= 7
Pounds of peanut to buy = 7 pounds
Pounds of cashew to buy = 3 pounds
This question is basically asking you what the value of X is of the vertical angles.Vertical angles are also congruent which mean they are equal.
2x + 8 = 4x -6
-2x -2x
8 = 2x - 6
+6 +6
14 = 2x
/2 /2
7 = X
The correct answer would be 24%.

lyrics b
Step-by-step explanation:
t - student distribution should be use when dealing with normal distribution but the sample from the population is minor than 30 . Curves for t-student are similar to the curve for normal distribution flattened and with much more area under tails and as n (sample number) increase the cuve become more and more similat to normal curve
