Answer: 91

Step-by-step explanation:

4 (4 x 4) + 3 (3 x 3)

= 4 (16) + 3 (3 x 3)

= 64 + 3 (3 x 3)

= 64 + 3 (9)

= 64 + 27

= 91

Step-by-step explanation:

please find the given table in the attached file.

Its circulatory system point-slope type involves picking out the formula for two points. That marker shape is:

$\to y - y_1 = m (x - x_1 )$

In measure the slope m, we will use both levels. Or get one of the levels of teleport plugged in for $x_1 \ and \ y_1$ (both do not matter)

Phase 1: I can choose two points from a list for a calculation of m slope: (1, 22) and (3, 46)

The m slope =12

Phase 2: going to settle on one of the plug-in points for $x_1 \ and \ y_1$ :

I get: y - 22 = 12 (x - 1) formulas 1 of $x_1 \ and \ y_1$

If you choose to answer throughout the form of the a slope instead of a point slope form, you must modify Equation 1 to come in the form of a slope intercept.

Check the picture below.

$\bf \textit{surface area of a cone}\\\\ SA=\pi r\sqrt{r^2+h^2}+\pi r^2\qquad \implies SA=\pi (8)\sqrt{164}+ \pi (8)^2 \\\\\\ SA=8\pi \sqrt{164}+ 64\pi \implies \stackrel{\pi =3.14~\hfill }{SA\approx 522.65296}\implies \stackrel{\textit{rounded up}}{SA=522.65}$

Answer:

0.4364 = 43.64% probability that the disposal of such capacitors will be regulated.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
