Answer:

Step-by-step explanation:

Is "32+6 y = 3 2 x + 6" written correctly?  I'll assume y=32x+6 is the corerect equation.  If 32+6 y = 3 2 x + 6 is correct, reduce it to:  

6y = 32x-26

y = (16/3)x - 4.5 and follow the same steps

=====

An equation perpendicular to y=32x+6 will have a slope that is the negative inverse to the reference line slope, in this case 32.  The negative inverse of 32 is -(1/32).

The perpendicular line will be y = -(1/32)x+b.

To find a value for b, use the given point (-12, 15) and solve for b:

y = -(1/32)x+b

15 = -(1/32)*(-12)+b

b = 15- (12/32)

b = 14.625

y=-(1/32)x+14.625

Angles opposite to the equal sides of an isosceles triangle are equal, so the third angle in this triangle is also 61.  Now, you know all the angles in the triangle, you can use the Triangle Sum Theorem, which says that all the angles in a triangle add up to 180.

x + 61 + 61 = 180

x + 122 = 180

x = 58

Hope this helped!

Answer:

a° = 58°

b° = 48°

c = 74°

d° = 122°

Step-by-step explanation:

Angles on a straight line add up to 180°

58° + d° = 180°

d° = 180° - 58° = 122°

Alternate angles are equal.

a° = 58°

Angles in a triangle add up to 180°.

48° + 58° + c° = 180°

106° + c° = 180°

c° = 180° - 106° = 74°

Angles on a straight line add up to 180°

74° + 58° + b° = 180°

132° + b° = 180°

b° = 180° - 132° = 48°

Answer:

The population can be divided into strata so that the individuals in each stratum are as much alike as possible.

Step-by-step explanation:

In short, if you can group the population into subgroups and are interested in their sub properties, then use stratified random sampling. If not, and interested only in the entire population as a whole, then use simple random sampling.

Simple random sampling, as the name suggests, is simply sampling randomly from the population. It doesn't make any assumptions of sub-classifications about the given population and is only interested in sampling the population as a whole representative.

Stratified random sampling, as the name suggests, does sampling on strata( parts or subgroups divided in the population). The sampling then is done from each group proportionate to the group's size versus the population size.

  One example is when you've got red, green and blue colored balls as the population and you want to sample the population based on colors, then the colored groups are strata and thus, the sampling will be done on subgroups and such type of sampling will be called as stratified random sampling.

Simple random sampling doesn't care about sub-properties in the population. It consider the population as whole and doesn't differentiate classes in the population, unlike stratified random sampling.

Step-by-step explanation:

multiply the original coordinate by 3

The image with the dilation of scale factor of 1/3 is P'Q'R'S' are (-2. 3),(1, 2),(0, -3) and (-3, -2)respectively.

Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation. Also If the Dilation is from the center of the rectangle, then the distance of all the points of the rectangle from its center will get scaled by that one dilation factor.

The dilation with scale factor of 1/3 with the origin as the center of dilation,

Let the coordinates are (x, y) -- (kx, ky); where k is the scale factor i.e, 1/3.

This can be written as; (1/3x, 1/3y).

For the point   P(- 6, 9)

The image of P' = (-2. 3)

For the point Q(3, 6)

The image of Q' (1, 2)

For the point R(0, - 9)

The image of R' (0, -3)

For the point S(- 9, - 6)

Image = (-3, -2)

Therefore, the image with the dilation of scale factor of 1/3 is P'Q'R'S' are (-2. 3),(1, 2),(0, -3) and (-3, -2)respectively.

Part a) the reflection in the line y = -x then image triangle P'Q'R'S';

P' = (-2, 2)

Q' = (1, -1)

R' = (0,3)

Answer:

f(x) = -1/2x + 1

Step-by-step explanation:

Remember that f(x) = y

f(-2) = 2   tells you that when x = -2,  y = 2 ;  So you have point (-2, 2)

f(2) = 0    tells you that when x = 2, y = 0 ;  So you have point (2, 0)

Now use the two points to find the slope:  Slope = (change in y)/(change in x)

So slope = (0-2)/(2-(-2) = -2/4 = -1/2

Next find "b" using the slope and one  point and solve for "b"

y = mx + b             slope = -1/2     point (-2, 2)

2 = -1/2(-2) + b

2 = 1 + b

1 = b

Last thing to do: write the equation using slope = -1/2 and b = 1 into y = mx + b

y = -1/2x + 1

4q+5(-5)/5=7

5x5=-25

4q-25/5=7

q=15

Answer:

q = 15

Step-by-step explanation:

We need to use inverse operations.

5 + 7 = 12

now the equation is 4q/5 = 12

what we do is  4 = 5 ⋅ 12

5 x 12 = 60

60 divided by 4 = 15

q = 15
