The percent error of Andy's estimation is 18.64 %
<u>Solution:</u>
Given, Andy estimated that he would need 70 feet of lumber for a tree house project
The actual amount of lumber needed was 59 feet
We have to find what was the percent error of Andy's estimation
<em><u>The error percentage is given as:</u></em>
Hence, the andy’s percent error is 18.64%
B.
Mean: 208.08
Median: 224.4
Mode: 122.4
Range: 183.6
First, we can make it easier by rearranging them from least to greatest in proper numerical form.
$120, $120, $220, $260, $300
Mean: (120 + 120 + 220+ 260 + 300)(1/5)=1020
1020 x 1.02( tax rate) = 1040.4
1040.4/5= 208.08
Median: %220 x 1.02= 224.4
Mode: 120 x 1.02 = 122.4
Range: (300 x 1.02)-(120 x 1.02)= 306-122.4
306 - 122.4 = 183.6
Answer:
Length of RU is 20 units.
Step-by-step explanation:
In ΔRSt and ΔRUT,
ST ≅ TU [Given]
RT ≅ RT [Reflexive property]
∠RTS ≅ ∠RTU [Both the angles are the right angles]
ΔRTS ≅ ΔRTU [By SAS property of congruence]
Therefore, RS ≅ RU [By CPCTC (corresponding parts of the congruent triangles are congruent]
8x = 6x + 5
8x - 6x = 5
2x = 5
x = 2.5
Length of RU = (6x + 5)
= 6(2.5) + 5
= 15 + 5
= 20
Length of RU is 20 units.
20+20-3-3-4 the 3 3 and 4 are beagative numbers
Answer:
This is GP with the first term of 512 and common ratio of 1/2
<u>The formula for nth term is:</u>
<u>The number of teams after the 4th round:</u>
- a₄ = 512*(1/2)⁴ = 32 teams
<u>Number of rounds to determine the champion:</u>
- 1 = 512*(1/2)ⁿ
- 2⁰ = 2⁹*2⁻ⁿ
- 0 = 9 - n
- n = 9 rounds
