Answer:

There is no basis for comparison because the effect of the other variables that are not being studied are not minimized

Step-by-step explanation:

The rate at which each type of ball bounce are;

Tennis balls;

The height to which the ball is must rebounds ≈ 111 cm

The height from which the ball is dropped = 200 cm

Surface = Steel plate

Basketballs;

The height to which the ball must rebounds ≈ 5.35 inches

The height from which the ball is dropped = 72 inches

Surface = Wooden floor

Squash balls

The height to which the ball must rebounds ≈ 29.5 inches

The height from which the ball is dropped = 100 inches

Steel plate at 70°

Therefore, given that the experimental are performed with different variables of height from which each type of ball is dropped, the surface to which the ball is dropped, the angle of the surface to which the ball is dropped, there is no controlled variable to provide a basis for comparison

Step-by-step explanation:

36 = 6* 6 = 2* 3 * 2* 3 = 2*2*3*3

180 = 2 * 2 * 3 * 3 * 5 = 2 * 2 * 3*3*5

[tex]\frac{36}{180}= \frac{2*2*3*3}{2*2*3*3*5} = \frac{1}{5}[/tex]

Answer:

13 times

Step-by-step explanation:

There are a total of 270 minutes in 4 1/2 hours.

270 ÷ 20 = 13.5

Though we know that 13.5 would not work out.

So she would check on it 13 times.

After the 13th time there will be 10 minutes left to cook the turkey.

The total number of times Alana will check the turkey before it sis done is 13 times.

The rate at which Alana is checking the turkey can be described as the work rate or the rate at which she is doing work.

The total number of times at which Alana will check the turkey before it is done is calculated as follows;

[tex]n = \frac{T}{R}[/tex]

where;

T is the total time = 4 1/2 h = (4 x 60) + 30 min = 270 min

R is the rate = 20 min

[tex]n = \frac{270}{20} \\\\n = 13.5 \ times\\\\n \approx 13 \ times[/tex]

There is no half checking, thus, the total number of times Alana will check the turkey before it sis done is 13 times.

Answer:

Equation: y = 2.5x

Answer: 43.75 drawers

Step-by-step explanation:

Equation: 10 - 7.5 = 2.5 and when you subtract 2.5 until the Number of Drawers (x) is 0, then you get 0 for Total Volume (y), so y =2.5x+0 or y = 2.5x

Answer: Substitute 17.5 into x.

y = 2.5(17.5)

y = 43.75 drawers

Answer:

b=42 degrees

c= 138 degrees

Step-by-step explanation:

B and the 42 degrees shown are congruent angles so therefore both are 42 degrees

To find C: We know that combining the 42 degrees and Angle C would form a flat angle or 180 degree angle, so therefore

subtract 180 with 42 to get Angle C

180-42= 138

Answer:

b=42, c=138

Step-by-step explanation:

B has to equal 42 because b is opposite of the 42º

and since 42+2c+42 has to equal 360, we simplify the expression to get:

84+2c=360,

2c=276

c=138

Step-by-step explanation:

The computation of the probability is shown below:

Given that

P(2,3, OR 4)

based on the above information

= 5C_2(0.4)^2 × (0.6)^3 + 5C_3(0.4)^3 × (0.6)^3 + 5C_4(0.4)^4 × (0.6)^1

= .3465 + .2304 + .0768

= .6528

Answer:

82 + (12 + 3 + 4) -10 = 91

82 + (12 times 3 + 4) -10 = 156

82 + (12 divided by 3 + 4) -10 = 73.71

82 + (12 - (3+4)) -10 = 77

I wasn't sure what the space between the 12 and the 3 + 4 meant so I put the answers to what it could have possibly meant.

Answer:

180 Vertical angles are opposite angles that share only a vertex.  Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.

This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.
