Y = 0.2x + 50
when you convert a percent to a decimal you move it two points to the left then add the 50 for daily earnings
Hassan is incorrect because √0.15 is less than 0.4, and the value of √0.15 is 0.3872 option third is correct.
<h3>What is the iteration method?</h3>
Iteration is the process of repeating a procedure in order to produce a series of results.
We have:
= √0.15
= (1.732)/(4.472)
= 0.3872
√0.15 is less than 0.4.
Thus, Hassan is incorrect because √0.15 is less than 0.4, and the value of √0.15 is 0.3872 option third is correct.

Answer:
= - 12 + 316 i
Step-by-step explanation:
Given that -
z = 3 + i
<em> = </em>
<em> = 9 + + 6 i</em>
<em> = 9 - 1 + 6 i</em>
= 8 + 6 i
<em> = × z</em>
<em> = ( 8 + 6 i ) × ( 3 + i )</em>
<em> = 24 + 8 i + 18 i + 6 i²</em>
<em> = 24 + 26 i - 6</em>
= 18 + 26 i
= ×
<em> = ( 8 + 6 i ) × ( 18 + 26 i )</em>
<em> = 144 + 208 i + 108 i + 156 i²</em>
<em> = 144 + 316 i -156</em>
= - 12 + 316 i
Answer:
12.3
Step-by-step explanation:
Step 1
We find the mean
The data list shows the scores of ten students in Mr. Smith's math class. 61, 67, 81, 83, 87, 88, 89, 90, 98, 100
Mean = Sum of terms/Number of terms
Number of terms = 10
Mean = 61 + 67 + 81 + 83 + 87 + 88 + 89 + 90 + 98 + 100/10
Mean = 844/10
Mean = 84.4
Step 2
Standard deviation
The formula for sample standard deviation =
√(x - Mean)²/n - 1
= √[(61 - 84.4)² + (67 - 84.4)² + (81 - 84.4)² + (83 - 84.4)² + (87 - 84.4)² + (88 - 84.4)² + (89 - 84.4)² + (90 - 84.4)² + (98 - 84.4)² + (100 - 84.4)²]/10 - 1
=√ 547.56 + 302.76 + 11.56 + 1.96 + 6.76 + 12.96 + 21.16 + 31.36 + 184.96 + 243.36/10 - 1
= √1364.4/9
= √151.6
= 12.31259518
Approximately to the nearest tenth = 12.3
The standard deviation = 12.3
