The cost of one ounce of soup will be $0.20

<u><em>Explanation</em></u>

A carton of milk containing 12 cans of soup costs $38.40 and each can weighs 16 ounces.

So, the total weight of 12 cans of soup $=(16*12)ounces=192 ounces$

That means, the cost of 192 ounces of soup is $38.40

Thus, the cost of one ounce of soup $=\frac{38.40}{192}=0.20$ dollar.

Answer:

$52.60

Step-by-step explanation:

Start with 135.10 and subtract the withdrawls (60, 45)

135.10-60-45 = 30.10

Add the deposit 22.50

30.10 + 22.50 = 52.60

For which of the following is x = -5 a solution? Select all that apply.

ser-zykov [4K]

Answer:

b. -x^2 + 50 = 25

c. |2x| = 10

d. x < 0

e. 2x < 10

Step-by-step explanation:

x = -5

-(-5)² + 50

-25 + 50 = 25

|2(-5)| = |-10| = 10

-5 < 0

2(-5) = -10 < 10

9. A computer chip manufacturer knows that 72% of the chips produced are defective.

adoni [48]

The probability that exactly 800 chips are acceptable is less than 0.000001

<h3>How to determine the probability?</h3>

The given parameters are:

Sample, n = 3000
Percentage acceptable, p = 72%
Acceptable chips, x = 800

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1- p)^{n - x}$

So, we have:

$P(300) = ^{3000}C_{800} * (72\%)^{800} * (1- 72\%)^{3000 - 800}$

The data values are large.

So, we use a statistical calculator to evaluate the expression

Using the calculator, we have:

P(300) < 0.000001

Hence, the probability that exactly 800 chips are acceptable is very small i.e. less than 0.000001
