The equation is 18.1 - x = -0.7

18.1 - -0.7 =
18.1 + 0.7 = 18.8

18.1 - 18.8 = -0.7

Florida’s 3-month temperature is 18.8 degrees C warmer than Montana’s.

<h3>Answer: 90 cubic meters</h3>

Each triangle has a base of 10 and height of 3.6

area of triangle = 0.5*base*height = 0.5*10*3.6 = 18 square meters

multiply this with the height of the prism (5 meters) to get 18*5 = 90 cubic meters. I'm using the idea that,

volume of prism = (area of base face)*(height of prism)

The notation "m^3" is shorthand for "cubic meters"

We do not use the other dimensions of 9 m and 7 m.

The number of column inches of classified advertisements appearing on Mondays in a certain daily newspaper is normally distribut

lana66690 [7]

Answer:

The probability there will be between 280 and 360 column inches of classified advertisement

P(280≤X≤360) = P(-2≤Z≤2) = 0.9544

Step-by-step explanation:

Given that the mean the population = 320

The standard deviation of the Population = 20

Let 'X' be the random variable in a normal distribution

Let 'X' = 280

$Z = \frac{x-mean}{S.D} = \frac{280-320}{20} = -2$

Let 'X' = 360

$Z = \frac{x-mean}{S.D} = \frac{360-320}{20} = 2$

The probability there will be between 280 and 360 column inches of classified advertisement

P(280≤X≤360) = P(-2≤Z≤2)

= P(z≤2) -P(z≤-2)

= P(z≤2)+P(z≤2)

= 2P(z≤2)

= 2×0.4772 ( from normal table)

= 0.9544
