Max cost of 15 bats = 15 x 35 = $535

Min cost of 15 bats = 15 x 20 = $300


Max cost of 12 gloves = 12 x 60 = $720

Mix cost of 12 gloves = 12 x 30 = $360


Min total cost = 360 + 300 = $660

Max total cost = 535 + 720 = $1255

The range is from  $660 to $1255

=============> Answer (A) is out of the range

Executives from Six Flags, a well-known amusement park chain, had interest in constructing a Six Flags theme park in a location
natima [27]

Answer:

The mean of the sampling distribution for the sample proportion when taking samples of size 500 from this population is equal to 0.248.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Of the 500 people sampled, 124 said that they would be interested in purchasing season tickets to a Six Flags in Ames.

This means that p = \frac{124}{500} = 0.248

The mean of the sampling distribution for the sample proportion when taking samples of size 500 from this population is equal to

By the Central Limit Theorem, it is equal to the sample proportion of 0.248.

Emergency i need the answer please HELP!
KatRina [158]

Answer:

41

Step-by-step explanation:

Theorem:

The measure of any exterior angle of a triangle is equal to the sum of the measures of the remote interior angles.

The angle measuring b + 41 is an exterior angle.

The angles measuring b - 2 and b + 2 are the remote interior angles to the exterior angle.

According to the theorem:

b - 2 + b + 2 = b + 41

2b = b + 41

b = 41

Maricopa's Success scholarship fund receives a gift of $ 75000. The money is invested in stocks,
Airida [17]

Answer:

Maricopa's Success invests $25,000 in stocks, $40,000 in bonds, and $10,000 in CDs.

Step-by-step explanation:

a = Stocks

b = Bonds

c = CDs

a + b + c = 75000

b = 30000 + c

a = 75000 - c - 30000 - c = 45000 - 2c

0.065(45000 - 2c) + 0.044(30000 + c) + 0.0225c = 3610

2925 - 0.13c + 1320 + 0.044c + 0.0225c = 3610

0.0635c = 635

c = 10000

So b = 40000 and a = 25000
