It grows by 10% each year. multiply the number by 0.1, then add. so 0.1×2420 is 242. add 242+2420=2662.
short answer:
this years tuition is $2662.
next years tuition is $2928.

The diagonals of a kite are perpendicular to each other, hence
∠EHF = 90°
The sum of the 3 angles in a triangle = 180°
In ΔEHF
∠1 + ∠2 + 90 = 180, that is
42 + ∠2 + 90 = 180
132 + ∠2 = 180 ( subtract 132 from both sides )
∠2 = 48°
26
DE and DG are congruent sides, hence
4x - 2 = 22.5 ( add 2 to both sides )
4x = 24.5 ( divide both sides by 4 )
x = 6.125
27
∠A and ∠C are congruent, hence
∠A = ∠C = 82°
The sum of the interior angles of a kite = 360°, hence
x = 360 - (82 + 82 + 140) = 360 - 304 = 56

Answer:
a) 2.5% b) 50%
Step-by-step explanation:
1300 is two standard deviations higher than the mean. Since 95% of the data is covered within two standard deviations to the left and right of the mean, 5% is not covered. So, we have 2.5% leftover on the left side of the curve, under 900, and 2.5% leftover on the right side of the graph that is above 1300.
The mean is 1100, so anything above or below the mean is exactly 50% in a normal distribution.
The total amount of money they collected for the charity is 29.1 pounds
<h3>How to find the total amount they collected?</h3>
100 pence = 1 pounds
Hence,
52 twenty pence coins = 1040 pence = 1040 / 100 = 10.4 pounds
59 ten pence coins = 590 pence = 590 / 100 = 5.9 pounds
26 five pence coins = 130 pence = 1.3 pounds
5 fifty pence coins = 250 pence = 2.5 pounds
9 £1 coins = 9 pounds
Therefore,
The amount of money collected = 10.4 + 5.9 + 1.3 + 2.5 + 9 = 29.1 pounds
