How to find the area of each face of a prism

tatiyna

If the face is a square, then (l*l)

If the face is a triangle, then (b*h)(1/2)

If the face is a rectangle, then (l*w)

If the face is a circle, then (r²)(3.14)

You can then add all these faces up to get the total surface area of the prism.

Suppose the average price of gasoline for a city in the United States follows a continuous uniform distribution with a lower bou

Novay_Z [31]

Answer:

$P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a} , a \leq X \leq b$

And for this case we can write the probability like this:

$P(X$

And then the final answer for this case would be $\frac{2}{3}=0.667$

Step-by-step explanation:

For this case we define our random variable X "price of gasoline for a city in the USA" and we know the distribution is given by:

$X \sim Unif (a=3.5, b=3.8)$

And for this case the density function is given by:

$f(x) = \frac{x}{b-a}= \frac{x}{3.8-3.5}=, 3.5 \leq X \leq 3.8$

And we want to calculate the following probability:

$P(X$

And we can use the cumulative distribution function given by:

$F(x) = \frac{x-a}{b-a} , a \leq X \leq b$

And for this case we can write the probability like this:

$P(X$

And then the final answer for this case would be $\frac{2}{3}=0.667$

emmainna [20.7K]

Answer:

1 adult cat

Step-by-step explanation:

Thursday:

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

$3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16$

There were 16 adult cats

Tuesday:

17 adult cats were at the pet care center.

Difference:

$17-16=1$ adult cat
