1. A local pizzeria sold 65 pizzas yesterday. (a) The owner offers the employees a bonus if the number of pizzas sold increases

Ad libitum [116K]

I think the answer is

65 + 0.20(65) = 65 + 13 = 78..they would have to sell 78 to get the bonus

(65 - 60) / 65 = 5/65 = 0.0769 x 100 = 7.69 rounds to 7.7 % decrease compared to the 65 pizza's sold yesterday

Not completely sure though, but
Hope It Helps

A basketball scout has developed a screening tool to identify future NBA all-stars. The screening tool is fairly reliable; 95% o

Over [174]

Answer:

The value is $P(F) =0.0095$

Step-by-step explanation:

From the question we are told that

The probability that a player is being identified as an NBA all-stars is 95% = 0.95

The number of player in the camp is n = 100

Generally the probability that a player becomes the first person to be evaluated is mathematically represented as

$p(1) = \frac{1}{n}$

=> $p(1) = \frac{1}{100}$

=> $p(1) = 0.01$

Generally the probability that the first basketball player his screening tool identifies as a future NBA all-star is truly a future NBA all-star

$P(F) = P(1) * 0.95$

=> $P(F) =0.01 * 0.95$

=> $P(F) =0.0095$

Solve each equation 3x^2=80

Lapatulllka [165]

Answer:

$x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$

or

$x = \frac{\pm4\sqrt{15}}{3}$

Step-by-step explanation:

Hello!

Use the quadratic formula: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

First, let's convert our equation to standard form of a Quadratic: ax² + bx + c = 0

3x² = 80

3x² - 80 = 0

Note, thats the value of b will be 0, as there is no "bx"

Now, solve:

$x = \frac{-(0) \pm \sqrt{(0)^2 - 4(3)(-80)}}{2(3)}$ Plug in values
$x = \frac{\pm\sqrt{960}}{6}$ Simplify the radical (Discriminant)
$x = \frac{\pm8\sqrt{15}}{6}$ Pull out perfect squares
$x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$ Reduce factors

The solutions are $x = \frac{4\sqrt{15}}{3}, x = \frac{-4\sqrt{15}}{3}$
