elixir [45]

Answer:

The answer to your question is: letter a

Step-by-step explanation:

data

balls diameter = 0.75 in then radius = 0.375 in

rectangular prism =   length = 3 in width = 3 height = 7.5 in

Formula

Rectangular prism volume = l x w x h = 3 x 3 x 7.7 = 67.5 in³

ball volume = 4/3 (3.1416)(r³) = 4/3 (3.1416)(0.375)³ = 0.220in³

 but   0.220in³ ------------------- 100 %

             x          -------------------  190%

  x = 0.418 in³

Finally divide the rectangular prism volume by ball volume

# of balls = 67.5 / 0.418 = 161.4 ≈ 160

The area of the following rectangle is 30 square units. What is the value of x
amid [387]
Hi there.


A = 30, w = 5, l = x - 2

We can divide the area by the width to find the length.

\frac{30}{5} = 6

8 - 2 = 6

<em /><em>x = </em>8

Which statement about the stamps is correct?
Elina [12.6K]

Answer: C.) The total number of stamps is 35.

Step-by-step explanation:

Given the table :

No of 45-cent stamp - - - No of 65-cent stamp

- - - - - - - 18 - - - - - - - - - - - - - - 17

- - - - - - - 20 - - - - - - - - - - - - - - - 15

- - - - - - 22 - - - - - - - - - - - - - - 13

- - - - - - 10 - - - - - - - - - - - - - - - - 25

Verifying each option stated :

Total value of stamp:

Each row add up to 35. Example (18 + 17) = 35

(20 + 15) = 35

(22 + 13) =35

(10 + 25) = 35

Total value of stamp:

Using the first row:

45 cent = $0.45 ; 65 cent = $0.65

(10 * 0.45) + (25 * 0.65)

= $4.5 + $16.25 = $20.75

Not all rows add up to $19.15

Discuss how the t-test for correlated groups and the t-test for single samples are alike and different.
SOVA2 [1]
In one sample t-test, you compare it to some value that you already know to represent the population mean. In the t-test for correlated groups, the statistic is the difference between your two samples, which you test against the population mean difference.
