Lines m and n are parallel, as shown in the diagram below. What are the measures of angles A and B?

Mathematics

Dvinal [7]3 years ago

Answer:

a = 55° and b = 60°

Step-by-step explanation:

→ Remember 2 key points about angles

  • Angles in a triangle add up to 180°
  • Alternate angles are equal

→ Angle a is alternate to 55° so using the 2nd point,

a = 55°

→ Remember the fact that angle in a triangle add up to 180°

55°  + 65° + b = 180°

→ Collect the whole numbers

120° + b = 180°

→ Minus 120° from both sides to isolate b

b = 60°

Step-by-step explanation:

since m and n are parallel so the right side of b are equal 65degree. 180-55-65 to get B is 60 degree. After that, 180-60-65 will get the A is 55degree

Which of the following sets would have a graph with an open circle on 2 and a ray pointing left on the number line?
andreyandreev [35.5K]

Answer:

{x | x∈ R, x < 2}

Step-by-step explanation:

Given

Open circle on 2

Arrow pointing left

Required

Determine the inequality

An open circle on 2 means represents either < or >

The arrow points to the left of -2 means that the number line represents numbers less than 2. i.e. < 2

Represent the numbers with x.

The inequality is: x < -2

Using proper notation, the inequality is:  {x | x∈ R, x < 2}

What is the probability that a randomly selected male will have a foot length between 8 and 12.5 inches? P(8 &lt; r &lt; 12.5)=
melisa1 [442]

Answer:

0.8185 or 81.85%

Step-by-step explanation:

The mean length (μ) of an adult foot is 11 and the standard deviation (σ) is 1.5.

The z score is a measure in statistic used to determine the amount of standard deviation by which the raw score (x) is above or below the mean. If the raw score is above the mean, the z score is positive  and if the raw score is below the mean the z sore is negative. It is given by:

z=\frac{x-\mu}{\sigma}

To calculate the probability that a randomly selected male will have a foot length between 8 and 12.5 inches, we first calculate the z score for 8 inches and then for 12.5 inches.

For 8 inches:

z=\frac{x-\mu}{\sigma}=\frac{8-11}{1.5}=-2

For 12.5 inches:

z=\frac{x-\mu}{\sigma}=\frac{12.5-11}{1.5}=1

From the normal distribution table, The probability that a randomly selected male will have a foot length between 8 and 12.5 inches = P(8 < x < 12.5) = P(-2 < z < 1) = P(z < 1)  - P(z < -2) = 0.8413 - 0.0228 = 0.8185 = 81.85%
