Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

log_{10}(y) = 2.447

In order to find the value for y, one must simply apply the following logarithmic property:

if : log_{b}(a) = c

then: b^c = a

Applying it to this particular problem:

log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280

Therefore, the regression line predicts y will equal 280 when x equals 5.

Step-by-step explanation:

Answer:

the equation of a “street” that passes through the building site and is parallel to Santa Cruz Boulevard

Step-by-step explanation:

The slope is find by 2 points on line  is calculated as;  

Equation of line is in slope-intercept form is written as;

         

We can easily take two points from given graphs are

(2,5) and (6,7)

The slope of line is;

the slope of line is  

Now, find the equation of line with the  slope-intercept form

Add both the sides by 5 in above expression,

Therefore, the equation of a “street” that passes through the building site and is parallel to Santa Cruz Boulevard

Match each radius or diameter of a circle with its approximate circumference.
jok3333 [9.3K]

Answer:

radius: 3 units <----> Circumference: 18.84 units

Diameter: 12 units <----> Circumference: 37.68 units

Diameter: 36 units <----> Circumference: 113.04 units

Radios: 5 unites <----> Circumference: 31.4 units

Step-by-step explanation:

How I got the answers for the radiuses:

3 (this is only half the diameter so if you do 3 x 2 you will get the diameter.)

3 x 2 = 6

C = pi x d

C = 3.14 x 6

C = 18.84 [this is the first radios]

5 (this is only half the diameter so if you do 5 x 2 you will get the diameter.)

5 x 2 = 10

C = pi x d

C = 3.14 x 10

C = 31.4 [this is the second radios]

How I got the diameters:

12 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 12

C = 37.68 [this is the first Diameter]

36 (this is the full diameter so we do not have to multiply it by 2)

C = pi x d

C = 3.14 x 36

C = 113.04 [this is the second Diameter]
