Answer:

49.2

Step-by-step explanation:

First you do SA=2Lw+2Lh+2wh

So then you get 2 x 1 1/5 x 5 + 2 x 1 1/5 x 3 + 2 x 5 x 3

After doing the math, you get 12+7.2+30

Then you get 49.2

Answer:

$x=70$

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

$\frac{0.35}{\frac{2}{3}x } =\frac{0.45}{x-10}$

Step 2: Solve for x

Cross-multiply: $0.35(x-10)=\frac{2}{3} x \cdot 0.45$
Distribute 0.35: $0.35x - 3.5=\frac{2}{3} x \cdot 0.45$
Multiply: $0.35x - 3.5=0.3x$
Isolate x term: $-3.5=-0.05x$
Isolate x: $70=x$
Rewrite: $x=70$

Step 3: Check

Plug in x to verify it's a solution.

Substitute: $\frac{0.35}{\frac{2}{3}(70) } =\frac{0.45}{70-10}$
Multiply: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{70-10}$
Subtract: $\frac{0.35}{\frac{140}{3} } =\frac{0.45}{60}$
Evaluate: $0.0075=0.0075$

Answer:

Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.

Step-by-step explanation:

In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.

Statistically, this means that the person can be 97% sure (not 100%) that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.

Small sample size may also lead wrong estimates.
