The y-intercepts of the lines will help you choose the correct answer. The orange line with postive slope has a y-intercept of 2, so its equation is
  y = 2x+2 . . . . . . . . eliminates all but the last 2 choices

The green line with negative slope has a y-intercept of 1, so its equation is
  y = -1/2x +1 . . . . . . eliminates all but the last choice

The point is (-3, 1), which confirms the last choice as being correct.

Martha drew the following shape on her
zalisa [80]

Answer:

  right angles and obtuse angles

Step-by-step explanation:

We assume that anything that <em>looks like</em> a right angle <em>is</em> a right angle.

The angles at the left end of each horizontal line are right angles.

The angles at the right end of each horizontal line are obtuse angles.

The angle where the diagonal lines meet is a right angle.

The shape contains right angles and obtuse angles.

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator
777dan777 [17]

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)

What is 2/4 in simplest form
Gennadij [26K]
2/4 in simplest form:

First, to find the simplest form of a fraction, you'll need to find the greatest common factor (GCF). To do this, we can list the factors of 2 and 4 and find the first common one.

Factors of 2: 1, 2
Factors of 4: 1, 2, 4

Since 2 is our first common factor, it is our GCF.

Second, we can now take our GCF (2) and divide it with our numerator and denominator. We will get a new numerator and denominator.

2 \div 2 = 1  \\  4 \div 2 = 2

Answer in fraction form: \fbox {1/2}
Answer in decimal form: \fbox {0.5}

Ordered data:

74.1, 74.2, 74.9, 77.9, 79.6, 80.9, 81.3, 82, 82.5, 82.7

minimum: 74.1

quartile 1: 74.9

quartile 2 (median): (79.6 + 80.9)/2 = 80.25

quartile 3: 82

maximum: 82.7

25% of data is below quartile 1

50% of data is below quartile 2

75% of data is below quartile 3
