Answer:

375 in³

Step-by-step explanation:

Given that V varies directly with l then the equation relating them is

V = kl ← k is the constant of variation

here k = 15 and l = 25, hence

V = 15 × 25 = 375 in³

Which equation below would be best solved by using the addition property of equality?

Svetradugi [14.3K]

Answer: F-23=45

Step-by-step explanation:

The addition property of equality means that if:

A = B

then we can add the same thing in both sides of the equation, and the equality will remain balid, so:

A + C = B + C.

Then, the correct answer is the last option:

F - 23 = 45

Then we can add the same number to both sides, we can add 23 to both sides and in this way isolate F:

F - 23 = 45

(F - 23) + 23 = 45 +23 = 68

F + (23 - 23) = 68

F = 68

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.
