Brandon buys a radio for $45.45 in a state where the sales tax is 7%.
svlad2 [7]
Given : Brandon buys a radio for $45.99 .sales tax rate is 7%.sales tax is a consumption tax imposed by the government on the sale of goods and services.
Let the price of Radio before the sales tax be $x. Sales tax on $x is 7% x.
Price before sales tax + Amount of sales tax= Cost of Radio.
x+7%x =45.99
Or x+0.07x=45.99
1.07x=45.99
Dividing both sides by 1.07.
x= 41.11
Cost of Radio before tax = $41.11
Sales tax paid = 43.99-41.11= 2.88
Tax paid = $2.90 (To nearest cent)

Answer:

  20.25 mm

Step-by-step explanation:

Arc length is given by the relation ...

  s = rθ

where r is the radius and θ is the central angle in radians.

There are π radians in 180°, so the arc length is ...

  s = (5 mm)(232°×π/180°) = 20.25 mm

The arc length is about 20.25 mm.

sume that the change in daily closing prices for stocks on the New York Stock Exchange is a random variable that is normally dis
Darina [25.2K]

Answer:

0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the z-score of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of $0.35 and a standard deviation of $0.33.

This means that \mu = 0.35, \sigma = 0.33.

What is the probability that a randomly selected stock will close up $0.75 or more?

This is 1 subtracted by the p-value of Z when X = 0.75. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{0.75 - 0.35}{0.33}

Z = 1.21

Z = 1.21 has a p-value of 0.8869.

1 - 0.8869 = 0.1131

0.1131 = 11.31% probability that a randomly selected stock will close up $0.75 or more.
