Based on a​ survey, assume that ​48% of consumers are comfortable having drones deliver their purchases. Suppose that we wan
Andru [333]

Answer:

The value of n is the size of the sample, the number of customers selected.

The value of p is 0.48.

The value of q is 0.52.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

48% of consumers are comfortable having drones deliver their purchases.

This means that p = 0.48, q = 1 - p = 1 - 0.48 = 0.52

The value of n is the size of the sample, the number of customers selected.

A pair of shoes is on sale for 30% off. The original price is p. Which expression can be used to find the price of the shoes aft
Sidana [21]

The correct option is b which is 0.70p.

Given to us,

original price of shoes = p,

Discount on shoes = 30%

As we know after giving the discount the value of the shoes will be 70% of the original price, therefore,

\bold{p=100\%\ price\ of\ shoes = \dfrac{100}{100}\times p = p}

After 30% discount,

\bold{p=(100\%-70\%) price\ of\ shoes}

\bold{p=70\%\ price\ of\ shoes = \dfrac{70}{100}\timesp= 0.7p }

Hence, the correct option is b which is 0.70p.

Some of the steps in the derivation of the quadratic formula are shown. Step 4: StartFraction negative 4 a c + b squared Over 4
s344n2d4d5 [400]

The reason why we used plus or minus when taking the square root is because; The square root of terms separated by addition and subtraction cannot be calculated individually.

<h3>How to use the quadratic formula?</h3>

The general formula for a quadratic equation is;

ax² + bx + c = 0

Now, the steps to derive quadratic formula to find the roots of this equation are as follows;

Step 1; Divide both sides of the equation by a to get;

x² + (b/a)x + c/a = 0

Step 2; Transpose the quantity c/a to the right side of the equation to get; x² + (b/a)x =  -c/a

Step 3; Complete the square by adding b²/4a² to both sides of the equation to get; x² + (b/a)x + b²/4a² =  -c/a + b²/4a²

Step 4; Factor the left side and combine the right side to get;

(x + (b/2a))² = (b² - 4ac)/(4a²)

Step 5:  Extract the square-root of both sides of the equation to get;

x + (b/2a) = ±(√(b² - 4ac))/2a

The reason why we used plus or minus when taking the square root is because The square root of terms separated by addition and subtraction cannot be calculated individually.
