Answer:

Area of a tire in the drawing = 113.14 cm²

Step-by-step explanation:

Kiara is drawing a photo of a car using a scale factor of 3.

A scale factor of 3 means that the new lengths will be 3 times the original lengths.

Now, if the radius of each of the car's tires is 2 cm, then the radius of each tire in the drawing will be (2 × 3) = 6 cm.

Therefore, the area of a tire in Kiara's drawing will be = πr² = \frac{22}{7} \times 6^{2} = 113.14 cm². (Answer)

The Jonas school district gives awards to its schools based on overall student attendance. The data for attendance are shown in
Evgesh-ka [11]
The most consistent attendance is the one that has less variability (it's more regular). Not necessarily the one with more students. So, the case with less variability is the one with less IQ, sigma or range (all three measure the dispersion of a distribution. IQ is more robust than sigma, and sigma more than the range, although in practice everyone uses sigma).

So, the answer to A) is the third High School: HS P

B) Here one looks at the central measurement: mean, median. This example is not super easy. HS N has the highest mean value, but HS P has the highest median. The median is more robust than the mean, since it is less affected by outliers. So HS P is a good candidate.

Finally, looking at the Low/High values, one can see that the high is the same: some day(s) when all students went and all HS have a maximum number of 180 students. However, the highest low is HS P.

So, I think HS P should also be awarded for the highest rate, since its median
is the highest and the lower number of students is the highest.

Median means 50% of the cases have values less than the median. Mean is an average.

Multiply or divide as indicated. Leave your answer with no factors in the denominator. p⁻⁴q⁵r⁶/p⁻³qr⁻²
KIM [24]

Answer: \frac{q^4r^8}{p}

Step-by-step explanation:

By the Negative exponent rule, we know that:

a^{-1}=\frac{1}{a}

By the Quotient of powers property, we know that:

\frac{a^m}{a^n}=a^{(m-n)

And by the Product of powers property, we know that:

(a^m)(a^n)=a^{(m+n)}

Applying this properties, we get:

\frac{p^{-4}q^5r^6}{p^{-3}qr^{-2}}=\frac{p^3q^5r^6r^2}{p^4q}=\frac{q^4r^8}{p}
