2x-3y=9 Find the x- and y-intercepts and graph the equation plotting the intercepts. Please show all of your work.
Llana [10]
To find where graph is intercepting x and y axis all we have to do is to calculate what is value of x when y = 0 (x intercept) and what value of y is when x = 0 (y intercept)

1)   x = 0
-3y = 9
y = -3

2)  y = 0
x = 9/2

Graph is bellow.

How many faces does the polyhedron have?
NikAS [45]

9514 1404 393

Answer:

  5

Step-by-step explanation:

We presume the figure is a rectangular pyramid and that there are two hidden faces, one on the bottom and one at the back.

We can see 3 faces, so adding the two we presume we can't see, there are a total of 5 faces on this polyhedron.

The upper arm length of females over 20 years old in a country is approximately Normal with mean 35.8 centimeters (cm) and stand
lana [24]

Answer:

a) The range of lengths from 28.3 cm to 43.3 cm covers almost all (99.7%) of this distribution.

b) 16% of women over 20 have upper arm lengths less than 33.3 cm.

Step-by-step explanation:

The Empirical Rule(68-95-99.7 Rule) states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 35.8 cm

Standard deviation = 2.5 cm

(a) What range of lengths covers almost all (99.7%) of this distribution?

This range is from 3 standard deviations below the mean to three standard deviations above the mean.

So from 35.8 - 3*2.5 = 28.3 cm to 35.8 + 3*2.5 = 43.3 cm

The range of lengths from 28.3 cm to 43.3 cm covers almost all (99.7%) of this distribution.

(b) What percent of women over 20 have upper arm lengths less than 33.3 cm?

68% of the women over 20 have upper arm length between 33.3 cm and 38.3 cm. The other 32% have upper arm length lower than 33.3 cm or higher than 38.3. The distribution is symmetric, so 16% of the have upper arm length lower than 33.3 cm and 16% have upper arm length higher than 38.3 cm

So 16% of women over 20 have upper arm lengths less than 33.3 cm.

What is the surface area of the figure<br><br><br><br> a:441<br> b:301<br> c:252<br> d:175
kow [346]

Answer:

  d.  175 square inches

Step-by-step explanation:

If we assume the base is square and all triangular faces are congruent, then the lateral area of the figure is that of four triangles. Each triangle has an area that is half the product of its base and height:

  A = (1/2)bh = (1/2)(7 in)(9 in) = 31.5 in^2

The area of the square base is the product of its length and width, both of which are 7 in.

  A = lw = (7 in)(7 in) = 49 in^2

So, the total surface area is that of the base plus the four sides:

  surface area = (49 in^2) + 4(31.5 in^2) = 175 in^2 . . . . . matches choice D
