Answer:

Step-by-step explanation:

The surface area of the given solid will be the sum of areas of all of its sides. From the given figure we can see that the sides(faces) of the solid are:

2 Equilateral Triangles

3 Squares

The Area of each triangle is 4 square units. So we need to calculate the area of the squares.

Side length of square = 3 units

Area of square = Length² = 3² = 9

Surface Area of Given Solid = Area of 2 Triangles + Area of 3 Squares

= 2(4) + 3(9)

= 8 + 27

= 35 square units

Surface Area of Given Solid = 35 square units

Mazyrski [523]

Answer:

0.8413 or 84.13%

Step-by-step explanation:

Given : The mean is 72 inches and the standard deviation is 15 inches

To Find : What is the probability that in a randomly selected year, the snowfall was less than 87 inches

Solution:

Mean = $\mu = 72$

Standard deviation = $\sigma = 15$

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

We are supposed to find the probability that in a randomly selected year, the snowfall was less than 87 inches

So, x = 87

Substitute the values in the formula

$z=\frac{87-72}{15}$

$z=1$

Now to find P(z<87) refer the z table

P(Z<87)=0.8413 = 84.13%

So, the probability that in a randomly selected year, the snowfall was less than 87 inches if the mean is 72 inches and the standard deviation is 15 inches is 0.8413 or 84.13%

sesenic [268]

Answer:

Step-by-step explanation:

Answer:

100/275=x/37

Step-by-step explanation:

37 heads for 100 guests that means the ratio is 37/100

To calculate how many is needed for 275 guests we should to multiply 275 by 37 and divide it by 100

And the expression for it is 100/275 = x/37
