  • ➡30 is correct answer
  • ➡option b is correct

\large\huge\green{\sf{Answer:-}}

<h3>since we know on straight line 180° is formed</h3><h3>then </h3>

➡90° +(x+x+x)= 180°

➡90° + 3x = 180°

➡3x= 180°-90°

➡3x= 90°

➡x = 90°/3= 30°

<h2>➡x= 30°</h2>

<h3>then in triangle sum of all angles = 180°</h3>

➡90°+x+y = 180°

➡90°+ 30° +y = 180°

➡120+y = 180°

➡y= 180°-120°

<h3>y = 60</h3>

  • now to find y-x = 60°-30°=30

➡30 is correct answer

➡option b is correct

Assume that a randomly selected subject is given a bone density test. Those test scores are normally distributed with a mean of
Effectus [21]

Answer:

Step-by-step explanation:

To find this probability, we shall be using the z-score route

Mathematically ;

z-score = (x -mean)/SD

From the question, x = 1.99, mean = 0 and SD = 1

So z = (1.99-0)/1 = 1.99

So the probability we want to calculate is;

P(z<1.99)

This value can be obtained from the standard normal distribution table.

P(z < 1.99) = 0.9767

The sketch of the region is as shown as in the attachment.

ehidna [41]

Answer:

1,260 mg of copper.

Step-by-step explanation:

This is because in a 3 to 1 ratio, the first number has to be 3 times the second number which is just multiplied by one. since zinc is the second number, it stays the same but the copper as to be 3 times the amount of zinc so 420 mg times 3 which equals 1,260.

The weight in kilograms is 20, so the stretch in cm is 20/3 = 6 2/3 cm.

When the 60 cm spring is stretched an additional 6 2/3 cm, its length will be ...

  60 +6 2/3 = 66 2/3 . . . cm
