First simplify.
-\frac{2}{3}x \ \textgreater \  \mathrm{Multiply\:fractions}:\ \:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c} \ \textgreater \  -\frac{2x}{3}

\mathrm{Multiply\:both\:sides\:by\:-1\:\left(reverse\:the\:inequality\right)} \ \textgreater \ \ \textgreater \  \frac{2x}{3}\ \textless \ -8

\mathrm{Multiply\:both\:sides\:by\:}3 \ \textgreater \  \frac{3\cdot \:2x}{3}\ \textless \ 3\left(-8\right) \ \textgreater \  Simplify \ \textgreater \  2x\ \textless \ -24

\mathrm{Divide\:both\:sides\:by\:}2 \ \textgreater \  \frac{2x}{2}\ \textless \ \frac{-24}{2} \ \textgreater \  Simplify \ \textgreater \  x\ \textless \ -12

Therefore\; x\ \textless \ -12 \;is\;our\;answer!

Hope this helps!

Which best explains the formula?
satela [25.4K]

Answer:

Therefore the first option is the best to explain the above Formula.

The central angle measure of the sector divided by the  total angle measure of a circle multiplied by the area of  the circle will yield the area of the sector.

Step-by-step explanation:

Given:

∠ ZYX = center angle

ZY = XY =Radii of Same Circle

Yellow Color Area in the Figure below = area

of the shaded sector

Solution:

Area Of Sector For an angle 'θ' is given as

\textrm{Area Of Sector}=\dfrac{\theta}{360\°}\times \pi r^{2}

Where,

\theta=\textrm{Center Angle}\\\\360\°=\textrm{Total Angle measure of a Circle}\\\\\pi r^{2}= \textrm{Area of a Circle}

Here,

Center Angle is ∠ ZYX = θ

Therefore the first option is the best to explain the above Formula.

The central angle measure of the sector divided by the  total angle measure of a circle multiplied by the area of  the circle will yield the area of the sector.

A new battery is expected to have a storage capacity of 60 ampere-hour (A h). A sample is tested, resulting in a 2-side confiden
antoniya [11.8K]

Answer:

Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %    

Step-by-step explanation:

We are given the following in the question:

Mean storage capacity = 60 ampere-hour

95% confidence interval =

63\leq \mu \leq 72

Thus, the correct answer based on the confidence interval is

Option B) The battery storage capacity is significantly different than 60 Ah, at a confidence level of 95 %

Since it is a two sided test we test whether the mean storage capacity is 60 Ah or different than 60 Ah

Thus, the battery storage is different from 60 Ah because the mean storage capacity does not lie in the 95% confidence interval.
