6 Mateo and Katia each walked into a
inna [77]

Answer:

(amounts could be:)

Katia: $3.50

Mateo: $1.75

Step-by-step explanation:

<em>Remember that a quarter = $0.25, 4 quarters = $1.00</em>

<h3>We know that they both have 38 quarters ($9.50) </h3>

<em>after an hour of playing games in the arcade, Katia has $1.75 more than Mateo</em>

lets say that Katia has <em>(random amount)</em><em>$3.50(14 quarters) </em>and Mateo has $1.75 less than that.

$3.50 - $1.75 = $1.75

<h3>Katia has $3.50 and Mateo has $1.75.</h3>

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.
zhannawk [14.2K]

Answer:

a) 0.6032

b)

Lower limit: 0.48

Upper limit: 0.72

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

Question a:

In a random sample of 63 professional actors, it was found that 38 were extroverts.

We use this to find the sample proportion, which is the point estimate for p. So

\pi = \frac{38}{63} = 0.6032

Question b:

Sample of 63 means that n = 63

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6032 - 1.96\sqrt{\frac{0.6032*0.3968}{63}} = 0.4824

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6032 + 1.96\sqrt{\frac{0.6032*0.3968}{63}} = 0.724

Rounding to two decimal places:

Lower limit: 0.48

Upper limit: 0.72

Write y = 4/3 * x - 2/3 in standard form <br><br> Helpplppppp
raketka [301]

Answer:

4x - 3y = 2

Step-by-step explanation:

First, let's review what "standard form" signifies:  Ax + By = C.

Starting with y = 4/3 * x - 2/3, multiply all three terms by 3 to eliminate the fractions:

3y = 4x - 2

Next, subtract 3y from both sides:

0 = 4x - 3y - 2.

It would be nice (tho' not essential) to have the coefficient of x positive.  That is why I've left 4x on the right side and subtracted 3y from both sides.

finally, add 2 to both sides, obtaining 4x - 3y = 2.  This is the equation in standard form.
