Answer: The cost per ounce of the peanut butter is $0.182.

Step-by-step explanation: Given that a grocery store sells an 18 ounce container of peanut butter for $3.28.

We are to find the cost per ounce of peanut butter.

We will be using the UNITARY method to solve the problem.

Cost of 18 ounces of peanut butter = $3.28.

So, the cost of 1 ounce of peanut butter is given by

$\dfrac{3.28}{18}=\$0.182.$

Thus, the cost per ounce of the peanut butter is $0.182.

Here,
cost of 18 ounce container of peanut butter = $3.28
cost of 1 ounce container of peanut butter = $3.28/18
=$0.182

We flip a fair coin five times. For every heads you pay me $1 and for every tails I pay you $1. Let X denote the my net winning

TEA [102]

Answer:

The probability mass of X is 0.03

Step-by-step explanation:

If we set the winning requirement of your heads and my tails then the occurring possibility of both is 1/2 or 0.5.

Hence let us make a graph and use the figures to calculate the all the probabilities of you getting a heads.

Where X represents the number of dollars won during the flip of the coin, probability of heads represent the chances of occurrence of the value and of winning the dollars.

The probability of winning start to drop as the winning amount increases.

X 0 1 2 3 4 5

Probability of Heads 0 0.50 0.25 0.13 0.06 0.03

Which equation can be used to find the length of Line segment A C? Triangle A B C is shown. Angle A C B is 90 degrees and angle

taurus [48]

Answer:

AC = 10sin(40°)

Explanation:

The diagram representing the question is shown in the attached image

Since the given triangle is a right-angled triangle, we can apply the special trig functions

These functions are as follows:

sin(θ) = opposite / hypotenuse

cos(θ) = adjacent / hypotenuse

tan(θ) = opposite / adjacent

Now, in the given diagram:

θ = 40°

AC is the side opposite to θ

AB = 10 in is the hypotenuse

Based on these givens, we will use the sin(θ) function

Therefore:

$sin(40) = \frac{AC}{10}\\ \\AC = 10sin(40)$

Write an expression that can be used to multiply 6 times 198 mentally

Zigmanuir [339]

I would half 198, get
99 and add a 0, this is how you multiply by 5 in your head

198*5 = 990
990 + 200 = 1190 - 2
= 1188

Alternatively we can round 198 to 200: then multiply by 6

200*6 = 1200

Then We subtract the 6 "2's" that we added

1200 - 12 = 1188

The expression for this is:
(6*200) - (6 * 2)

Write the expression 6^7/12 in radical form.

Marat540 [252]

$In\\general
\\ a^{ \frac{x}{y} } = \sqrt[y]{a^{x}} 

For our example,

\\ \\6^{ \frac{7}{12} = \sqrt[12]{6^{7}}$
