What is the value of y?<br> Y<br> Y<br> 60<br> O A. 120°<br> B. 60°<br> C. 40°<br> O D. 30°
Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

  • (y+y)+(60)=180
  • 2y + 60 = 180

Step 2: Subtract 60 from both sides.

  • 2y + 60 - 60 = 180 - 60
  • 2y = 120

Step 3: Divide both sides by 2.

  • \frac{2y}{2}=\frac{120}{2}
  • y = 60

Step 4: Check if solution is correct.

  • (60)+(60)+60 = 180
  • 120 + 60 = 180
  • 180 = 180

Therefore, the answer is B. 60°.

scoundrel [369]

Answer:

-6.134 to +6.134

Step-by-step explanation:

given that a large population of variable x is characterized by its known mean value of 6.1 units and a standard deviation of 1.0 units and a normal distribution

X is Normal with mean  =6.1 and std dev = 1 unit

We are to determine the range of values containing 70% of the population of x

We know that normal distribution curve is bell shaped symmetrical about the mean.

So to find 70% range we can use 35% on either side of the mean

Using std normal distribution table the value of z for which probability from 0 to z is 0.35 is 1.034

Hence corresponding x value is

x=6.1+1.034*1\\x=6.134

i.e. 70% values lie between

-6.134 to +6.134
