Answer:
m∠A = 20°
Step-by-step explanation:
Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.
2x + 5x + 11x = 180
18x = 180
18x/18 = 180/18 or x = 10
m∠A = 2x or 2(10) = 20°
m∠B = 5x or 5(10) = 50°
m∠C = 11x or 11(10) = 110°
Out of the choices given, the only one that is true is that m∠A = 20°.
Answer:
4/15
Step-by-step explanation:
1) find common denominator, 15 in this problem
2) solve
Answer:
a) $432
b) (i) $8970
Step-by-step explanation:
Given that:
Ratio of Cost of Hansi and Megan is 7 : 4.
Hansi's holidays cost = $756
Hansi's earnings in 2008 = $7800
In 2009, there are 15% more earnings than in 2008.
To find:
Cost of Megan's holiday.
Earnings in 2009 ?
Solution:
As per given question statement,
Let the holiday cost of Hansi = 7
Let the holiday cost of Megan = 4
As per question statement:
We have to find the value of 4 now.
b)(i)
Earnings in 2009:
$7800 + 15% of $7800
Answer: B) 160
<u>Step-by-step explanation:</u>
Since the Standard deviation of 21 bins is 3 bins, then the first 7 bins falls in the first 2.5% edge of the bell curve.
2.5% of 21 times 1000 = (0.025)(21)(1000) = 160
Answer:
<em>Hello, If you arrange the data in ascending order , the bar graph will show sharp incline.</em>
<em />
<em>When you arrange the data in descending order , the bar graph will show sharp decline.</em>
<em />
<em>Now, if you will draw the bar graph without interfering at the data chances are it may show decline and then incline or incline and then decline.</em>
