The ratio of the combined volume of the pyramids to the volume of the prism,expressed as a fraction in simplest form,is 1/3.

The volume of a pyramid is (1/3) (base area) (height)

Volume of the lower pyramid = (1/3) (base area) (height) Volume of the upper pyramid = (1/3) (basearea × height)

The combined volume of both pyramids = (2/3) × (base area) (height) .

Their base area is  (length x width) of the prism, and their height is  (1/2 the height) of the prism.

From here, we'll work with the dimensions of the prism ... L, W, and H .

Combined volume of the pyramids = (2/3) (L x W) (1/2 H)

=  (1/3) (L x W x H) .

Volume of the prism  =  (L x W x H)

The pyramids occupy 1/3 the volume of the prism.

The ratio is  1/3 .

Answer:

[tex]x=\frac{7\pm\sqrt{61} }{6}[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

3p² - 7p - 1 = 0

Step 2: Identify Variables

a = 3

b = -7

c = -1

Step 3: Find roots

Answer:

x = 7 + √61 ÷ 6

Step-by-step explanation:

3p² - 7p - 1 = 0 is a given equation

3p² - 7p - 1 = 0

Here,

a = 3

b = - 7

c = - 1

Now, Discriminant

D = b² - 4ac

= (- 7)² - 4 (3)(- 1)

= 49 + 12

D = 61 > 0

So, Quadratic Equation

ax² + bx + c = 0

x = - b ± √b² - 4ac ÷ 2a

x = - (- 7) ± √(- 7)² - 4 (3)(- 1) ÷ 2(3)

x = 7 ± √61 ÷ 6

x = 7 ± √61 ÷ 6

x = 7 + √61 ÷ 6 or x = 7 - √61 ÷ 6

∴ Not real Value

Thus, The real value of x is 7 + √61 ÷ 6

The linear regression equation that represents this set of data is Y = -12.41 + 1.15x and the projected test  grade for a student with a homework grade of 49 is 44 and this can be determined by using the generalized equation of regression.

Given :

The generalized regression equation is given below:

Y = a + bX   --- (1)

where b is given by the formula:

[tex]\rm b = \dfrac{N\sum XY-\sum X \sum Y}{N\sum X^2-(\sum X)^2}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'b'.

b = 1.15

and the formula of a is given below:

[tex]\rm a = \dfrac{\sum Y - b \sum X}{N}[/tex]

Now, substitute the values of the known terms in the above formula in order to determine the value of 'a'.

a = -12.41

Now, substitute the values of a and b in the equation (1).

Y = -12.41 + 1.15x

Now, at x = 49 the value of Y becomes:

Y = -12.41 + 1.15(49)

Y = 43.94

Y [tex]\approx[/tex] 44

Step-by-step explanation:

If the die is rolled then the probability of the roll is a prime number is [tex]\frac{4}{10}=\frac{2}{5}[/tex]. The probability that the same number would appear twice on the dice is [tex]0.01[/tex], and the expected value of the roll is [tex]5.5[/tex].

Expected value (EV), which is based on a random variable's probability distribution, describes the long-term average level of that variable. The expected value of a stock or other investment is a crucial factor in investing and is taken into account while performing scenario analysis. The anticipated value is an extension of the weighted average in probability theory. Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen. Find the anticipated value by [tex]E(X)[/tex]. Simply multiply each value of the discrete random variable by its probability, then add the results to get the value, or mean, of the random variable. The equation is provided as [tex]E(X)[/tex]=μ=Σ[tex]XP(X)[/tex]. Expected value is calculated by multiplying each outcome's value by the probability.

Total Number of outcomes is [tex]10[/tex]. And the number of prime number is [tex]4 \ \ i.e.\ (2,3,5,7)[/tex]. So the probability of a prime number is [tex]\frac{4}{10}=\frac{2}{5}[/tex]

The expected value is ×[tex]XP(X)= 0*\frac{1}{10}+1 * \frac{1}{10} + 2*\frac{1}{10} +3*\frac{1}{10} +4*\frac{1}{10} +5*\frac{1}{10} +6*\frac{1}{10} +7*\frac{1}{10} +8*\frac{1}{10} +9*\frac{1}{10} \\ =0+\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}+\frac{5}{10}+\frac{6}{10}+\frac{7}{10} +\frac{8}{10}+\frac{9}{10} \\ =\frac{1+2+3+4+5+6+7+8+9}{10}=\frac{55}{10}=5.5[/tex]

If the dice is rolled twice the probability that the same number is obtained is [tex]\frac{1}{10}*\frac{1}{10}=\frac{1}{100}=0.01[/tex]

Answer:

C

Step-by-step explanation:

the unit right below yards is ft so we can mark out A

we also know that there are 3 feet in 1 yard and that in order for the unit yard to cancel out, the 1 yard needs to be the denominator to 3 feet, so we can mark out D

the unit right below feet is inches and we know that there are 12 inches in one foot, so we can mark out B

this leaves us with C

The equation of the straight line that has x-intercept 1 and y-intercept 4 is:

4x - y = 4

"A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined on both sides of a point."

Given, the line has a x-intercept of 1 and y-intercept of 4. T

Therefore, the line passes through the points (1, 0) and (0, 4).

Now, we can find the slope of the line 'm' that passes through those either points.

Therefore, (x₁ - x₂) = m(y₁ - y₂)

⇒ (1 - 0) = m(0 - 4)

⇒ m = [tex]\frac{1}{4}[/tex]

Now, the equation of the line that has x-intercept 1 and y-intercept 4 is:

(x - x₁) = m(y - y₁)

⇒ (x - 1) =      [tex]\frac{1}{4}[/tex](y - 0)

⇒ 4(x - 1) = y

⇒ 4x - y = 4
