Answer:

Step-by-step explanation:

A)

This is the 30% discount:

$39.99 x .30 = $11.997; The discount is $11.997

Price of headphones after the discount:

$39.99 - $11.997 = $27.99

Now we need to calculate the 6% sales tax on the discounted price.

$27.99 x .06 = $1.68 (rounded off)

Dalton paid $1.68 in sales tax on the discounted price.

B)

The total price Dalton paid for the headphones will be the discounted price plus the sales tax.

$27.99 + $1.68 = $29.67

Total price Dalton paid: $29.67

The average summer temperature in Anchorage is 69°F. If the daily temperature is normally distributed with a standard deviation
mafiozo [28]

Answer:

81.85%

Step-by-step explanation:

Given :

The average summer temperature in Anchorage is 69°F.

The daily temperature is normally distributed with a standard deviation of 7°F .

To Find:What percentage of the time would the temperature be between 55°F and 76°F?

Solution:

Mean = \mu = 69

Standard deviation = \sigma = 7

Formula : z=\frac{x-\mu}{\sigma}

Now At x = 55

z=\frac{55-69}{7}

z=-2

At x = 76

z=\frac{76-69}{7}

z=1

Now to find P(55<z<76)

P(2<z<-1)=P(z<2)-P(z>-1)

Using z table :

P(2<z<-1)=P(z<2)-P(z>-1)=0.9772-0.1587=0.8185

Now percentage of the time would the temperature be between 55°F and 76°F = 0.8185 \times 100 = 81.85\%

Hence If the daily temperature is normally distributed with a standard deviation of 7°F, 81.85% of the time would the temperature be between 55°F and 76°F.
