Correct option D) 1,185.6 inches cubed .

<u>Step-by-step explanation:</u>

Here we have , A triangular prism. The triangular base has a base of 12 inches and height of 10.4 inches. The height of the prism is 19 inches. We need to find  the volume of the triangular prism .Let's find out:

We have following parameters :

b=12 inches\\h=10.4inches\\l=19inhes

We know that , Volume of triangular prism is :

⇒ Volume = \frac{1}{2}b(h)(l)

⇒ Volume = \frac{1}{2}12(10.4)(19)

⇒ Volume = 6(10.4)(19)

⇒ Volume = 1,185.6in^3

Therefore , Correct option D) 1,185.6 inches cubed .

"How much do students pay, on average, for textbooks during the first semester in college? From a random sample of 400 students
dezoksy [38]

Answer: The margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

Step-by-step explanation:

Since we have given that

Sample size = 400

Mean = $357.75

Standard deviation = $37.89

At 95% confidence level, z = 1.96

We first find the margin of error.

Margin of error is given by

z\times \dfrac{\sigma}{\sqrt{n}}\\\\=1.96\times \dfrac{37.89}{\sqrt{400}}\\\\=3.71

95% confidence interval would be

\bar{x}\pm \text{margin of error}\\\\=357.75\pm 3.71\\\\=(357.75-3.71,357.75+3.71)\\\\=(354.04,361.46)

Hence, the margin of error = 3.71, confidence interval = (354.04, 361.46) and it means that mean cost is lies within the confidence interval.

What are all the angle measures for right triangle ABC?
Alenkasestr [34]

Answer:

\alpha = 60°,\:\beta = 30°, \: 90°

Step-by-step explanation:

Arccos( \frac{ \sqrt{3} }{2} ) =  \beta  \\ Arccos(  \cos \: 30 \degree ) =  \beta  \\30 \degree =  \beta  \\  \therefore \:  \alpha  = 60 \degree \\ remaining \: angle = 90 \degree \\

Divide 128 chairs among 3 rooms in the ratio of 1 : 3 : 4.​
Alex_Xolod [135]

Answer:

Step-by-step explanation:

1x+3x+4x= 128

8x=128

x=128/8

x=16

therefore,

room 1 = 1x

           = 1*16=16

room 2 = 3x

            =3*16=48

room 3 = 4x

            =4*16=64

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne
Mrrafil [7]
<h3>Answer:  Choice C.   (1,0)</h3>

============================================================

Explanation:

Point H is at (-2,2) and J is at (4,-2)

Focusing on the x coordinates, the midpoint is (x1+x2)/2 = (-2+4)/2 = 1.

The y coordinates have a midpoint of (y1+y2)/2 = (2+(-2))/2 = 0.

The midpoint is at (1,0). That's why the answer is choice C.

--------------------------

This next section is optional.

Points I and K are located at (4,3) and (-2,-3) respectively

Averaging the x coordinates gets us (x1+x2)/2 = (4+(-2))/2 = 1

Doing the same for the y coordinates gets us (y1+y2)/2 = (3+(-3))/2 = 0

We end up with the same midpoint (1,0)

The midpoint being the same for both diagonals proves that each diagonal is bisected, ie cut in half.

What is the sum of the finite arithmetic series? 26 + 29 + 32 + 35 + 38 + 41 + 44
Leya [2.2K]
The sum of the finite arithmetic series of <span> 26 + 29 + 32 + 35 + 38 + 41 + 44 is 245. Arithmetic series is a sequence of number such that the difference between any term and the previous term is a constant number. When we sum a finite number of terms in the arithmetic series, we get the finite arithmetic series. </span>
