Answer:

  • A. Points A, B, and D are on both planes.
  • B. Point H is not on plane R.
  • D. Points C, D, and A are noncollinear.
  • E. The line containing points F and G is on plane R.

Step-by-step explanation:

A. Points A, B, and D are on both planes.

  -- true. These points are on the line of intersection of the planes, so are in both planes.

B. Point H is not on plane R.

  -- true. Point H is not shown as being on either of the identified planes.

C. Plane P contains point F.

  -- false. Point F is shown as being in plane R, not P.

D. Points C, D, and A are noncollinear.

  -- true. Point C is not on the line containing points A and D.

E. The line containing points F and G is on plane R.

  -- true. F and G are both in plane R, so the line containing them will also be in that plane.

F. The line containing points F and H is on plane R.

  -- false. Point H is not in plane R, so will not be on any line in plane R.

Describe the equation 2x + 15 = 23 + x in words.
AveGali [126]

Answer:

x = 8

x = 21/14

x = 8

x = 15/21

x = 1/4

x = 7

Step-by-step explanation:

(For all instances of number, let it be x)

Double the sum of a number and 15. The result is the same as the product of 23 and the number.

2x + 15 = 23 + x

2x - x + 15 = 23 + x - x

x + 15 = 23

x + 15 - 15 = 23 - 15

x = 8

Multiply a number by 15 and add 2. The result is the same as the sum of 23 and the number.

15x + 2 = 23 + x

14x + 2 = 23

14x = 21

x = 21/14

Double a number and add 15. The result is the same as the sum of 23 and the number.

2x + 15 = 23 + x

x + 15 = 23

x = 8

Double a number and add 15. The result is the same as the product of 23 and the number. (This time we will move the x to the other side as the right side has a larger x than the left side)

2x + 15 = 23x

15 = 21x

x = 15/21

Multiply a number by 15 and add 2. The result is the same as the product of 23 and the number.

15x + 2 = 23x

2 = 8x

2/8 = x

x = 1/4

Double the sum of a number and 15. The result is the same as the sum of 23 and the number.

2(x + 15) = 23 + x

2x + 30 = 23 + x

x + 30 = 23

x = 7

*PLEASE ANSWER* (: Find the measure of angle A.
natka813 [3]

Answer:

B. 120°

Step-by-step explanation:

If two tangents intersect in the exterior of a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.

m∠A° = 1/2(300 - 60)

m∠A° = 1/2(240)

m∠A° = 120

The 95% confidence interval for these parts is 56.98 to 57.05 under normal operations. A systematic sample is taken from the man
Nonamiya [84]

Answer:

Stop the line of production since the sample mean  (56.96) is outside the confidence interval [CI_{0.95} = ( 56.98, 57.05 )]

Step-by-step explanation:

Given that;

95% confidence interval for these parts is 56.98 to 57.05

CI_{0.95} = ( 56.98, 57.05 )

Sample mean = 56.96

We know that;

If the sample mean is within the confidence interval then, our decision is to keep the line operating as it is inside the confidence interval.

But if the sample mean is not within the confidence interval them, our decision is to stop the line of production as it is outside the confidence interval.

Now since our mean sample (56.96) does not lie between with the 95% confidence interval CI_{0.95} = ( 56.98, 57.05 ).

Therefore, Stop the line of production since the sample mean  (56.96) is outside the confidence interval [CI_{0.95} = ( 56.98, 57.05 )]
