Find the volume of a rectangular prism with the dimensions:
length: 4 yd
width: 5 ft
height: 11 ft
Answer:-Given:-[tex] \bullet [/tex] Length of a rectangular prism = 4 yards = 4 × 3 = 12 feet.
[tex] \bullet [/tex] Breadth of a rectangular prism = 5 feet.
[tex] \bullet [/tex] Height of a rectangular prism = 11 feet.
To Find:-The volume of a rectangular prism.
Solution:-We know,
Formula of Volume of a rectangular prism is (Length × Breadth × Height) cubic units.
So, Volume = (12 × 5 × 11) cubic feet
Volume = 660 cubic feet
The volume of a rectangular prism is 660 cubic feet. [Answer]In the hormone replacement studies of menopausal women, doctors rejected the results of the observational study after conducting the experiment. In the experiment they controlled the effects of confounding variables that had probably influenced the results in the observational study. In the experiment the doctors used random assignment to treatment groups, a placebo, and double blinding to control the effects of confounding variables. Which of the following are potential confounding variables? Check all that apply.
A. whether a woman took hormones
B. whether a woman in the study had a heart attack
C. wealth
D. access to health care
Answer:
A. whether a woman took hormones.
B. whether to woman in the study had a heart attack.
D. access to health care
Step-by-step explanation:
The study conducted to observe the menopausal woman must be supported with their health history. Some woman may have menopause at an early age while other go towards this at a later age. This can be due to smoking, hormone intake, severe diseases like heart attack or cancer and their routine health checkup details. There variables must be observed and included in experiment to reach a conclusion.

You have a bag of gummy worms. 12 are green, 3 are blue, 6 are red, and 2 are orange. What is the probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm?
The probability that you will reach into the bag and pull a red worm, eat it, and then pull a green worm:
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
The probability of pulling a red worm from the bag is 6/(12+3+6+2) = 6/23.
After eating the red worm, there are 11 green worms left in the bag, so the probability of pulling a green worm is 12/(12+3+2) = 12/17.
To find the probability of both events occurring (pulling a red worm and then a green worm), we need to multiply their probabilities:
P(red and green) = P(red) × P(green)
P(red and green) = (6/23) × (12/17)
P(red and green) = 72/391
Therefore, the probability of reaching into the bag and pulling a red worm, eating it, and then pulling a green worm is 72/391.

Lanna plotted 3 vertacies of a square on a coordinate plane witch are the coordinates of the missing vertext of lanas square
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the coordinates of the three vertices.
I will answer your question using the following illustration.
Assume that the square is ABCD are the given coordinates are:
[tex]A = (3,1)[/tex]
[tex]B = (-1,5)[/tex]
[tex]C = (-5,1)[/tex]
Required
Find D
Let the coordinates of D be:
[tex]D = (x,y)[/tex]
---------------------------------------------------------------------------------------------------------
Calculate the slope of each side.
AB, BC, CD and DA using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
AB:
[tex]A = (3,1)[/tex] -- [tex](x_1,y_1)[/tex]
[tex]B = (-1,5)[/tex] -- [tex](x_2,y_2)[/tex]
So:
[tex]m_1 = \frac{5 - 1}{-1 - 3} = \frac{4}{-4} = -1[/tex]
BC:
[tex]B = (-1,5)[/tex] -- [tex](x_1,y_1)[/tex]
[tex]C = (-5,1)[/tex] -- [tex](x_2,y_2)[/tex]
So:
[tex]m_2 = \frac{1-5}{-5--1} = \frac{-4}{-4} = 1[/tex]
CD:
[tex]C = (-5,1)[/tex] -- [tex](x_1,y_1)[/tex]
[tex]D = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]
So:
[tex]m_3 = \frac{y - 1}{x --5} = \frac{y-1}{x+5}[/tex]
DA
[tex]D = (x,y)[/tex] -- [tex](x_1,y_1)[/tex]
[tex]A = (3,1)[/tex] -- [tex](x_2,y_2)[/tex]
[tex]m_4 = \frac{1-y}{3-x}[/tex]
AB and CD are parallel sides. So, they have the same slope
i.e.
[tex]m_1 = m_3[/tex]
[tex]\frac{y-1}{x+5} = -1[/tex]
Solve:
[tex]y-1 =-x-5[/tex]
Make y the subject
[tex]y =-x-5+1[/tex]
[tex]y =-x-4[/tex] ---- (1)
BC and DA are parallel sides. So, they have the same slope
i.e.
[tex]m_2 = m_4[/tex]
[tex]1 = \frac{1-y}{3-x}[/tex]
Solve:
[tex]1-y =3-x[/tex]
Make y the subject
[tex]y =1-3+x[/tex]
[tex]y =x-2[/tex] ---- (2)
So, we have:
[tex]y =-x-4[/tex] and [tex]y =x-2[/tex]
Equate both:
[tex]y=y[/tex]
[tex]-x-4=x-2[/tex]
Collect like terms
[tex]-x-x=4-2[/tex]
[tex]-2x=2[/tex]
Solve for x
[tex]x = -\frac{2}{2}[/tex]
[tex]x = -1[/tex]
Substitute [tex]x = -1[/tex] in [tex]y =x-2[/tex]
[tex]y = -1-2[/tex]
[tex]y = -3[/tex]
So, the missing coordinate is:
[tex]D = (-1,-3)[/tex]

01) x = 2.5
2) x = 0.5
3) x = -0.5
04) x = 3.5
Step-by-step explanation:
9(x - 2) = 27
9x - 18 = 27
9x = 27 + 18
9x = 45
x = 45/9
x = 5

a car travels the first 15 km of the journey at an average speed 60km/h and the remaining 40 km at an average speed of 30 km/h find the average speed of the whole journey
Answer:
the average speed of the whole journey is 45 km/h
Step-by-step explanation:
The computation of the average speed of the whole journey is shown below:
Average speed is
= (Speed 1 + speed 2) ÷ 2
= (60 km/h + 30 km/h) ÷ 2
= 90 km/h ÷ 2
= 45 km/h
Hence, the average speed of the whole journey is 45 km/h
We simply ignored the distance as it is not relevant for the given situation

One bead for every member of the school orchestra is placed in a bag. All but 2 of the beads are white. Each member draws a bead from the bag, and the members who pick the non-white beads will represent the orchestra. It is predicted that two different instrument players will choose the white beads.
We are to say whether the conclusion is valid.
Answer:
Statement is valid.
Step-by-step explanation:
We are told that One bead is placed in a bag for every member of the school orchestra.
Also that all the beads except for 2 are white. Now, each member takes a bead from the bag and those who lick the non-white will represent the orchestra.
This tells us that this is an unbiased sample because it doesn't give anyone a better chance of picking non-white as every member of the school orchestra has an equal chance since it is randomly selected.
Thus, we can conclude that the statement that two different instrument players will choose the white beads is valid because we are dealing with an unbiased and simple random sampling

(2) Parv has a $50 gift card. He uses the gift card to buy a pack of games
for $9.99. He also wants to buy some movies (n). Each movie costs
$3.99. Which inequality describes how many movies Parv can buy?
Answer:
$50 - $9.99 = $40.01
$40.01 ÷ $3.99 = 10
so the answer is 10
Step-by-step explanation:
if thats not whats being asked sorry
Inequality shows a relationship between two numbers or two expressions.
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
The number of movies Parv can buy is 10.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal= ≥
We have,
Gift card = $50
Cost of a pack of games = $9.99
Cost of each movie = $3.99
x = number of movies
The inequality describes the number of movies Parv can buy.
9.99 + 3.99x ≤ 50
Where x is the number of movies.
Solve for x.
9.99 + 3.99x ≤ 50
Subtract 9.99 on both sides.
3.99x ≤ 50 - 9.99
3.99x ≤ 40.01
Divide both sides by 3.99
x ≤ 40.01/3.99
x ≤ 10
This means the number of movies Parv can buy is 10.
We can cross-check.
9.99 + 3.99 x 10 ≤ 50
9.99 + 39.9 ≤ 50
49.89 ≤ 50
Thus,
The number of movies Parv can buy is 10.

125^2 cannot equal 122^2 + 30^2, because 125^2 is odd and 122^2 and 30^2 are even
23^2 + 18^2 = 529 + 324 < 900 < 31^2
So it has to be the last one, and after verification we find it checks out and 28^2 + 195^2 = 197^2
