An experiment is designed to determine the launch angle that will give a projectile the greatest range (make it go the longest distance). The "launcher" is a slingshot type of apparatus that is spring-loaded and released by a trigger. For each trial, the same painted rock is retrieved and launched. Measurements are taken linearly from the launch site to the landing site. The trials were done on a windless day.Which of the following would be a good hypothesis for this experiment?

If the angle of the launcher is increased, the rock will go further.

Changing the angle of the launcher will vary the distance that the rock can be projected.

Answers

Answer 1

Answer:

If the angle of the launcher is increased, the rock will go further........

Answer 2

Answer: test each

if angle is increased, rock will go further
if the angle starts at 0, then increases to 90 degrees (straight up) the rock will go up then bounce off of the launcher going either front or back, but vastly shorter than if it were pointed straight ahead

2nd one
changing angle change the distance
we see that is true

The fourth column is labeled total with entries 53, 29, 82. Which is the marginal relative frequency for students who plan to attend college? Round the answer to the nearest percent. 18% 22% 35% 82%

Answers

Answer: 82%

Step-by-step explanation:

- - - - - - - - college - - not college - - - - total

Travel - - - - 43 - - - - - - - 10 - - - - - - - - 53

Not travel - 24 - - - - - - - 5 - - - - - - - - - 29

Total - - - - 67 - - - - - - - 15 - - - - - - - - - 82

Marginal relative frequency of students who plan to attend college:

(Number of students who plan to attend the college / Total number of the students)

Number of students who plan to attend college = 67

total number of students = 82

Marginal relative frequency = 67/82

= 0.8170731

= (0.8170731) * 100%

= 81.7% = 82%

I need help with an algebra assignment right away! Write the equation 9x + 2y = 6 in slope-intercept form.

Write the equation y - 3 = 4(x + 1) in standard form.

Write the equation y + 7 = -2(x - 3) in slope-intercept form.

The equation y - 5 = 3(x - 2)
is written in point-slope form. Write this equation in the
following ways:
a. slope-intercept form
b. standard form

Answers

So remember that slope-intercept form is y = mx+b (m = slope, b = y-intercept) and standard form is ax+by = c. (a and b are coefficients and c is the constant)

Starting with the first question: 9x + 2y = 6

Firstly, subtract 9x on both sides: 2y = -9x + 6

Next, divide both sides by 2, and your equation will be y = -4.5x + 3

Now with the next equation: y - 3 = 4(x + 1)

Firstly, foil 4(x + 1): y - 3 = 4x + 4

Next, subtract y on both sides: -3 = 4x - y + 4

Next, subtract 4 on both sides, and your answer will be: -7 = 4x - y

Next equation: y + 7 = -2(x - 3)

Firstly, foil -2(x - 3): y + 7 = -2x + 6

Next, subtract 7 on both sides of the equation, and your answer will be: y = -2x - 1

Next: y - 5 = 3(x - 2) (part a)

Firstly, foil 3(x - 2): y - 5 = 3x - 6
