Find 4 consecutive even numbers whose sum is 156?

faust18 [17]

X + (x + 2) + (x + 4) + (x + 6) = 156
   x + x + x + x + 2 + 4 + 6 = 156
       4x + 12 = 156
   - 12   - 12
   4x = 144
      4 4
   x = 36
   x = 36
x + 2 = 38
x + 4 = 40
x + 6 = 42

A shipment of thirteen smartphones contains three with cracked screens. if sold in a random order, what is the probability that

OLEGan [10]

The probability of a screen being damaged is:
P(d)=3/13=0.23
Thus to get the probability that the first 10 sold were undamaged we use the binomial distribution formula:
P(x)=n!/((n-x)!x!)p^x(1-p)^(n-x)
from the question:
n=13, x=10, p=0.23
hence
P(x)=13!/((13-10)!10!)*0.23^(13-10)*(1-0.23)^(10)
simplifying the above we get:
P(x)=0.255

Bags of almonds cost three dollars more than bags of pecans the owner of a bakery ordered five bags of almonds and three bags of

antiseptic1488 [7]

Answer:

Let bags of pecans cost = x

Make an equation :

Bags of almonds cost = x + 3 (they said almonds cost 3 dollars more)

Total number of bags ordered: (3 bags pecans) + (5 bags of almonds)

Cost for pecans = 3x

Cost for almonds = 5(x + 3) = 5x + 15

Price of pecans + price of almonds = total cost

Solve for x:

3x + 5(x + 3) = 55 (remove brackets)

3x + 5x + 15 = 55 (add like terms)

8x + 15 = 55

8x + 15 - 15 = 55 - 15 (get rid of the 15)

8x = 40

8x/8 = 40/8

x = 5

bags pecans cost is $5

bags of almonds is $5+$3 = $8
