The dot plots below show the test scores of seventh- and eighth-grade students: Dot plot for Grade 7 shows 6 dots on score 50, 4

dots on score 60, 6 dots on score 70, and 4 dots on score 80. Dot plot for Grade 8 shows 7 dots on score 60, 4 dots on score 70, 4 dots on score 80, 3 dots on score 90, and 2 dots on score 100. Based on visual inspection of the dot plots, which grade, if any, appears to have the higher mean score? Grade 7 Grade 8 Both groups show about the same mean score. No conclusion about mean score can be made from the data.

Find the midpoint of AB A B . Question 5 options: (4, 4) (1, 1) (3, 1) (10, 4)
zaharov [31]

A (-2, 0)

B (4, 2)

so mid point (x,y) of 2 coordinates(x1,y1) and (x2,y2) is given as

(x,y) = ( (x1+x2)/2 , (y1+y2)/2)

= ( (-2+4)/2, (0+2)/2)

= (2/2, 2/2)

= (1, 1)

so your answer is (1,1) that is option 2

A projectile is launched from ground level at an angle of 13.0 ° above the horizontal. It returns to ground level. To what value
Elden [556K]

Answer:

The launch angle should be adjusted to 30.63°

Step-by-step explanation:

The range of a projectile which is the horizontal distance covered by the projectile can be expressed as;

R =(v^2 sin2θ)/g

Where

R = range

v = initial speed

θ = launch angle

g = acceleration due to gravity

For the case above. When the projectile is launched at angle 13° above the horizontal.

θ1 = 13

R1 = (v^2 sin2θ1)/g

R1 = (v^2 sin26°)/g ....1

For the range to double

R2 = (v^2 sin2θ)/g .....2

R2 = 2R1

Substituting R2 and R1

(v^2 sin2θ)/g = 2 × (v^2 sin26°)/g

Divide both sides by v^2/g

sin2θ = 2sin26

2θ = sininverse(2sin26)

θ = sininverse(2sin26)/2

θ = 30.63°
