1. Frankie solved the equation below. Describe Frankie's mistake and record the correct olution. \[ \begin{array}{r}2.3 x-3.9+1.2 x-4.6=2 \\ 3.5 x-8.5=2 \\ 3.5 x=10.5 \\ x=7\end{array} \] ummarize today's lesson:

Scienze Un recipiente cilindrico contiene un miscuglio formato da limatura di ferro e polvere di zolfo. La polvere di zolfo ha una massa di 150 g , mentre la massa della limatura di ferro è \( \frac{1}{3} \) della massa totale. Calcola la massa dellali. matura di ferro e quella del miscuglio.

General Given a deck of 52 cards What is the probabilty that a card chosen at random will be 1.1 a hearts 1.2 a ten 1.3 a jack of diamonds

Using the definition, calculate the derivative of the function. Then find the values of the derivative as specified. \( g(t)=\frac{9}{t^{4}} ; g^{\prime}(-4), g^{\prime}(2), g^{\prime}(\sqrt{5}) \)

228. \( \left\{\frac{3}{5} \times\left[\left(\frac{1}{2}-\frac{1}{3}\right)^{2}: \frac{5}{24}+\frac{8}{15}\right] \times\left(1+\frac{1}{2}\right)^{2}+\left(1+\frac{1}{3}+\frac{1}{4}+\frac{1}{12}\right)\right\}: \frac{11}{3} \)

Exercise \#3. Calculate confidence intervals for proportion. Use the following information to complete the calculations. \[ \text { Formula: } P \pm Z \sqrt{\left(\frac{p(1-P)}{n}\right)} \] (3a) You are polling San Marcos to check support for a proposition that citizens will be voting on next election. The sample, \( n=500 \), indicates that the proportion of San Martians who support the proposition is 0.67 . Calculate the \( 95 \% \) and \( 99 \% \) confidence intervals for the proportion of San Martians who support the proposition.
