3 pounds of gummy bunnies are selling for $4.00. How much will 2 pounds cost?

Mashutka [201]

Most of the required important information's are already given in the question. Based on those given information's the answer to the question can be easily reached.
The cost of 3 pounds of gummy bunnies = $4
Then
The cost of 1 pound of gummy bunnies = (4/3) dollars
So
The cost of 2 pounds of gummy bunnies = (4/3) * 2 dollars
   = 8/3 dollars
   = 2 2/3 dollars
   = 2.67 dollars
So the cost of 2 pounds of gummy bunnies is 2 2/3 dollars or $2.67. I hope the procedure is simple enough for you to understand.

consider the distribution of monthly social security (OASDI) payments. Assume a normal distribution with a standard deviation of

Orlov [11]

Answer:

$\mu = x - z(\sigma)$

$\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15$

Therefore, the mean monthly payment is $1137.15.

Step-by-step explanation:

What is Normal Distribution?

We are given a Normal Distribution, which is a continuous probability distribution and is symmetrical around the mean. The shape of this distribution is like a bell curve and most of the data is clustered around the mean. The area under this bell shaped curve represents the probability.

We are asked to find the mean monthly social security (OASDI) payment.

Mean monthly payment = μ = ?

We are given that the standard deviation is $116

One-fourth of payments are above $1214.87

One-fourth means 25%

$P(X > x )= P(Z > z ) = 0.25\\\\P(X < x )= P(Z < z) = 1 - 0.25\\\\P(X < x )= P(Z < z) = 0.75\\\\$

From the z-table, the z-score corresponding to 0.75 is found to be 0.67

$z = 0.67$

The mean is found by

$x = \mu + z(\sigma)$

$\mu = x - z(\sigma)$

Where

x = $1214.87

z = 0.67

σ = $116

$\mu = 1214.87 - 0.67(116) \\\\\mu = 1214.87 - 77.72 \\\\\mu = \$1137.15$

Therefore, the mean monthly payment is $1137.15.

Lucy bought three books at a bookstore. Here are their prices (in dollars).

Valentin [98]

Answer:

41.82$

Step-by-step explanation:

The prices are

7.58$, 16$, 18.24$.

To get the total of all what Lucy bought, You add the prices altogether.

That is,

18.24$

+16.00$

+07.58$

41.82$

The total amount of what Lucy bought is 41.82$
