Answer: The better buy is the one where banana is sold for $0.80 per pound.

Step-by-step explanation:

At one farmer's market, bananas in the market cost $0.80 per pound while at another farmer's market, the bananas are sold in 5-pound bags for $4.50 per bag. In this market , a pound of banana will be sold for $4.50 divided by 5 which will be $0.9.

The firs market has banana sold as

at $0.80 per pound while in the second market, bananas are sold for $0.90 per bag since 5 pounds are sold for $4.50.

The better buy is the one where banana is sold for $0.80 per pound.

Divide the second amount by five to find out how much it costs at the second farmers market to get 1 pound of bananas.
5/5=1
4.50/5=.9
.9>.8 so the first farmers market had a better deal.

Answer:

slope = 1/4

Step-by-step explanation:

The slope of a line is defined by the rise (change in y-value)/run (change in x-value.  The change in y-value is 0 - (-2) = 0 + 2 = 2.  The change in x-value is -2 - (-10) = -2 + 10 = 8.  Therefore, the slope is 2/8 or (simplified) 1/4.

Global Airlines operates two types of jet planes: jumbo and ordinary. On jumbo jets, 25% of the passengers are on business while
MArishka [77]

Answer:

Answer:

The  probability is  P(J|B) =  0.36

Step-by-step explanation:

B =business

J=jumbo

Or =ordinary

From the question we are told that  

     The proportion of the passenger on business in the ordinary jet  is P(B| Or) =  0.25

     The proportion of the passenger on business in the jumbo jet  is  P(B|J)  =  0.30

     The  proportion of the passenger on jumbo jets is  P(j) = 0.40

      The   proportion of the passenger on ordinary jets is evaluated as

         1 - P(J) =  1- 0.40  =  0.60

According to  Bayer's theorem the probability a randomly chosen business customer flying with Global is on a jumbo jet is mathematically represented as

        P(J|B) =  \frac{P(J) *  P(B|J)}{P(J ) *  P(B|J) +  P(Or ) *  P(B|Or)}

substituting values

         P(J|B) =  \frac{ 0.4 *   0.25}{0.4 *  0.25 +  0.6 * 0.3}

         P(J|B) =  0.36

Find a cubic function f(x) = ax^3 + bx^2 + cx + d that has a local maximum value of 3 at x = −3 and a local minimum value of 0 a
Ahat [919]

Answer:

f(x) = (3x³ + 9x² - 27x + 15)/32

Step-by-step explanation:

f'(x) = 3ax² + 2bx + c

Maximum or minimum: f'(x) = 0

Maximum: f'(-3) = 0 and f(-3) = 3

Minimum: f'(1) = 0 and f(1) = 0

f'(-3) = 0 leads 27a - 6b + c = 0       (1)

f'(1) = 0 leads 3a + 2b + c = 0           (2)

f(-3) = 3 leads -27a + 9b -3c + d = 3    (3)

f(1) = 0 leads a + b + c + d = 0        (4)

(1) - (2):   24a - 8b = 0, or 3a - b = 0, b = 3a

(3) - (4)   -28a + 8b - 4c = 3    (5)

(1) * 4 + (5):  80a - 16b = 3,

use b = 3a, get 80a - 16*3a = 3, 32a = 3, a = 3/32, b = 3a = 9/32

From (2): c = -3a - 2b = -9/32 - 18/32 = -27/32

From (4): d = -a - b - c = -3/32 - 9/32 + 27/32 = 15/32

So

f(x) = (3x³ + 9x² - 27x + 15)/32
