A company tests the life of its rechargeable batteries over six months of use. They test how long a battery will last after a fu
jonny [76]

Answer:

18.6 months

Step-by-step explanation:

Given that :

Best fit line from scatterplot :

y=-12.05x +224.26

x = Number of month

y = charge on battery

Number of months a typical battery uses before being dead completely :

When battery is dead completely ; charge =0, y = 0

y = -12.05x + 224.26

0 = - 12.05x + 224.26

12.05x = 224.26

x = 224.26 / 12.05

x = 18.610788

Hence, 18.6 months before battery is completely dead.

The following gives information about the proportion of a sample that agree with a certain statement. Use StatKey or other techn
marishachu [46]

Answer:

(0.2278, 0.3322)

Step-by-step explanation:

Given that out of 400 people 112 agree and 288 disagree

Proportion of people agreeing = \frac{112}{400} =0.28

q=1-p =0.72\\se = \sqrt{\frac{pq}{n} } =0.03175

For confidence interval 90% we have critical value as

1.645

Margin of error =1.645*SE

=1.645(0.03175)\\= 0.0522

Confidence interval = (0.28-0.0522, 0.28+0.0522)\\= (0.2278, 0.3322)

Please Help!<br> The following is an isosceles trapezoid, find m &lt; J
ra1l [238]

Answer:

<em>The measure of angle J is 44°</em>

Step-by-step explanation:

<u>Isosceles Trapezoid</u>

The isosceles trapezoid has its non-parallel sides of the same length, thus the angles they form with their respective parallel sides are congruent.

It means: Angle J is congruent with angle K and angle M is congruent with angle L

The sum of angles in a trapezoid is 180*(4-2)=360°

Thus:

m\angle J+m\angle K+m \angle M+m\angle L = 360^\circ

7x+2+7x+2+25x-14+25x-14=360

Joining like terms:

64x-24=360

Adding 24:

64x=384

Dividing by 64:

x=6°

Thus:

m\angle J = 7*6+2=44^\circ

m\angle M = 25*6-14=136^\circ

The measure of angle J is 44°
