Zanzabum

Answer:

Yes the sales manager claims can be refuted based on the calculated percentages

Step-by-step explanation:

<u>From the table attached below </u>

Total number of customers = 200

<em>Calculated percentages</em><em> </em>

customers that prefer whole life insurance = 90 = 90/200 = 45%

customers that prefer universal life insurance = 15 = 15/200 = 7.5%

customers that prefer Annuities = 95 = 95/200 = 47.5

<em>Expected percentages:</em>

whole life = 20%

Universal life = 10%

Life Annuities = 70%

A person is on the outer edge of a carousel with a radius of 20 feet that is rotating counterclockwise around a point that is ce
lubasha [3.4K]
<h2>Answer:</h2>

\boxed{(5(-\sqrt{2}+\sqrt{6}),5(\sqrt{2}+\sqrt{6}))}

<h2>Step-by-step explanation:</h2>

The origin of the coordinate system is the center of the circle. So we have an angle that measures 5\pi/12=75^{\circ}. so the x-coordinate and y-coordinate can be found, by using trigonometry as follows:

x=20cos(5\pi/12)=5\sqrt{6}-5\sqrt{2} \\ \\ Arranging:\\ \\x=5(-\sqrt{2}+\sqrt{6}) \\ \\y=20sin(5\pi/12)=5\sqrt(6)+5\sqrt{2} \\ \\ Arranging:\\ \\y=5(\sqrt{2}+\sqrt{6})

Finally, the exact value of the position of the rider after the carousel rotates 5\pi/12 radians is:

\boxed{(5(-\sqrt{2}+\sqrt{6}),5(\sqrt{2}+\sqrt{6}))}

How do i solve by using substitution​
elena55 [62]

Answer:

a = 0, b = 3

Step-by-step explanation:

3a + b = 3

b = - 3a +3

2a - 5b = - 15

2a - 5(-3a + 3) = - 15

2a + 15a - 15 = - 15

17a = 0

a = 0

b = -3a +3 = - 3 *0 +3 = 3
