Answer:

  • 135°

Step-by-step explanation:

<h3>ΔQPR</h3>

<u>All interior angles are equal, so:</u>

  • m∠QPR = 180°/3 = 60°
<h3>ΔPRS</h3>

<u>Equilateral right triangle, so:</u>

  • m∠RPS = 90°/2 = 45°
<h3>ΔPST</h3>

<u>Right triangle with m∠T = 60°, so:</u>

  • m∠SPT = 90° - 60° = 30°

<u>Now we can find the required angle measure:</u>

  • m∠QPT = m∠QPR + m∠RPS + m∠SPT
  • m∠QPT = 60° + 45° + 30° = 135°

bonufazy [111]

Answer:

All answers are correct.

Step-by-step explanation:

Henry needs a total of 15 pints.

3 pints of yellow multiplied by 3 gives 9 pints of yellow, he needs 6 pints of red to get to 15, so he multiplies 2 pints of red by 3 to get 6 pints of red.

You add 9 + 6 to get the total of 15 pints he needs.

The mean speed of vehicles along a stretch of highway is 56 mph with a standard deviation of 4 mph. You
Elenna [48]

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.

<h3>Z score</h3>

Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

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

Where x is raw score, μ is mean, σ is standard deviation

Given that:

σ = 4, μ = 56, hence

for x = 62:

z=\frac{62-56}{4 } =1.5

for x = 47:

z=\frac{47-56}{4 } =-2.25

for x = 56:

z=\frac{56-56}{4 } =0

The corresponding z score for speed of 62 mph, 47 mph, and 56 mph is 1.5, -2.25 and 0 respectively.
