<h3>Answer: B) 11.75</h3>

=================================================

Explanation:

Points B, C, and D are midpoints of triangle AFE. This is due to the similar tickmarks showing how the segments are congruent (eg: AB = BE).

Because we have D and B as midpoints, this means segment DB is a midsegment of triangle AFE.

FE = 23.5, so half that is (1/2)*FE = 0.5*23.5 = 11.75 which is the length of DB.

The midsegment DB is half as long as FE, and DB is parallel to FE.

Nostrana [21]

Point slope from would be 12x-y+26=0.

Black is the equation, 12x-y+26=0.

  • Orange is <em>y-14=12(x+1)</em>
  • Blue is <em>y-14=12(x-1)</em>
  • Red is <em>y+14=12(x-1)</em>
  • Green is <em>y-14=-12(x+1)</em>

Answer:

1. Precise

2.Both

3.Precise

5.Neither

Step-by-step explanation:

Accuracy is the closeness of a measured value to a standard value.

Precision is the closeness of two or more measurements to each other.

1.The norm is 45 sit-ups in a minute.The students did, 64, 69,65 and 67. Values are not accurate compared to standard value 45.

Values are precise

Answer--Precise

2. Average score is 89.5

  Scores are 89,93,91,87

  Values are precise i.e a difference of 2 from each score

  Values are accurate because the average score is 90 thus compared to      the known average score of 89.5 they are accurate.

Answer-Both

3. Yesterday temperature=89

   Tomorrow=88

    Next day=90

   Average =75

   Values are precise i.e. difference of ± 1°

   Values are not accurate compared to the average temperatures of 75 F

   Answer---Precise

5. The jar contained 568 pennies

   The 6 people guessed the numbers as

    735,209,390,300,1005, 689

  The values are not precise

  The values are not accurate

  Answer---Neither

Consider the sphere enclosed by the cylinder. If the diameter of the sphere is 12 cm, what is the volume of the cylinder? A) 36π
kogti [31]
To find the volume of a cylinder , you will use the formula
V = Bh, where B is the area of the circular base.
Pi x r^2 x h
pi x 6^2 x 12
V = 432
The volume of the cylinder is 432pi cm³.

Can someone help me find the equation for this line please
pogonyaev

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1
