The travelers are adding a new room to their house. the room will be a cube with volume 3375 ft.³.they are going to put in hardwood floors, the contractor charges $10 per square foot. how much will the hardwood floors cost?
Answers
Answer:
$ 2250
Step-by-step explanation:
3375 = s³
s = ∛3375
s = 15 ft.
floor area = s² = (15 * 15)
floor area = 225 ft²
the contractor charges $10 per ft².
therefore,
the hardwood cost = 225 x $10 = $2250
Answer:
$2,250.
Step-by-step explanation:
So first, we need to find the area of the floor (the side shaded green). To do so, we first need to find the length of the one side of the room.
Since we know that the room is a cube, all side lengths are equivalent. And since we are given that the volume of the room is 3375, we can find the length of the side.
The volume of a cube is given by the formula:
[tex]V=s^3[/tex]
Substitute 3375 for V:
[tex]s^3=3375[/tex]
Take the cube root of both sides:
[tex]s=\sqrt[3]{3375}=15[/tex]
So, the side length of the room is 15.
This means that the area of the floor is:
[tex]A=(15)^2\\A=225\text{ in}^2[/tex]
They charge $10 per square foot. There are 225 square feet. Thus, the total cost will be:
[tex]10(225)=$2250[/tex]
$2,250.

(b) What is the probability that distance exceeds the mean distance by more than 2 standard deviations?
Answers
Answer:
>0.95
Step-by-step explanation:
This probably refers to a normal distribution. In a normal distribution, according to the empirical rule,
68% of observed data falls within 1 standard deviation of the mean
95% falls within 2 standard deviations of the mean
99.7% falls within 3 standard deviations of the mean
In this case, the observed data is distance and the average figure for all observed distances is the mean distance.
So, the probability that a/any distance observed exceeds the mean distance by more than 2 standard deviations is >95%
In other words, the probability is >0.95
This is a standard deviation contest. You must choose four numbers from the whole numbers 0 to 10 , with repeats allowed. (a) Choose four numbers that have the smallest possible standard deviation. What is s in this case? (Enter your answer rounded to the nearest whole number.)
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following instructions :
Choose 4 numbers from the whole numbers 0 - 10
Note : Repetition is allowed
Choose 4 numbers with the smallest possible standard deviation.
The smallest possible value of standard deviation obtainable is 0;
Hence in other to obtain a standard deviation value of 0, then;
The mean squared deviation value must be zero (0)
Σ(X - mean)^2 = 0
To achieve this, the values of X and the mean must be the same.
Hence all 4 numbers (X) must be the same in other to have a mean value which is equal to X
For instance :
If X = 3, 3, 3, 3 (since Repetition is allowed)
Man value = (3+ 3+ 3+ 3) / 4 = 12 / 4 = 3
Σ(3 - 3)² = 0 for all values of x
√Σ(x - mean)² / n = 0 ; if all values of x are the Same
n = Number of observations
A possible list of values is (3,3,3,3)

mg+rg=2H, solve for g
Answers
Answer:
g = 2H/(m + r)
Step-by-step explanation:
mg + rg = 2H
g(m + r) = 2H
(g(m + r))/(m + r) = 2H/(m + r)
g = 2H/(m + r)
The required solution of the algebraic expression for g is 2h / (m + r ).
Given that,
To simplify the algebraic expression mg+rg=2H for g,
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
the given algebraic expression is,
mg + rg = 2h
taking g common on left side,
g(m + r) = 2h
transposition of the term (m + r) to the denominator of the right-hand side,
g = 2h / (m + r)
The above expression is the required solution for the g.
Thus, the required solution of the algebraic expression for g is 2h / (m + r ).

18. A sum of money was shared among
Okpala, Olu and Bello such that
Okpala had one sixth of the money.
Olu had one quarter of the money
and Bello had the rest. By what
fraction of the money is Bello's share
greater than Okpala's and Olu's
shares put together?
Answers
Answer is something I’m not sure of
Bello's share is greater than Okpala's and Olu's shares combined by a fraction of 1/6 of the total sum of money.
Here, we have,
Let's assign variables to represent the shares of Okpala, Olu, and Bello.
Let M be the total sum of money.
Okpala's share = (1/6)M
Olu's share = (1/4)M
Bello's share = M - Okpala's share - Olu's share
To find the fraction of the money by which Bello's share is greater than Okpala's and Olu's shares put together, we need to calculate the difference between Bello's share and the sum of Okpala's and Olu's shares, and then express it as a fraction of the total sum of money M.
Bello's share - (Okpala's share + Olu's share) = (M - Okpala's share - Olu's share) - (Okpala's share + Olu's share)
= M - Okpala's share - Olu's share - Okpala's share - Olu's share
= M - 2(Okpala's share) - 2(Olu's share)
= M - 2[(1/6)M] - 2[(1/4)M]
= M - (1/3)M - (1/2)M
= M - (2/6)M - (3/6)M
= M - (5/6)M
= (1/6)M
Now, let's express this difference as a fraction of the total sum of money M:
Fraction of Bello's share greater than Okpala's and Olu's shares
= [(1/6)M] / M
= (1/6)
Therefore, Bello's share is greater than Okpala's and Olu's shares combined by a fraction of 1/6 of the total sum of money.

If Mitzi has two dogs, a puppy that weighs 25 pounds and an adult that weighs 80 pounds, how much will it cost to bathe them both? $105 $115 $150 $160
Answers
Answer:
The correct answer is A) $105
Step-by-step explanation:
In this real-world problem, the cost to groom both dogs is (the puppy) + (the adult dog) = x.
For the first step, y = 40, if x <= 25.
y = 50, if 25 < x < 50.
if x >= 50, then y = 0.50x + 25
So therefore, substitute the puppy + adult dog = x
25 + 80 = x
105 = x
So, the final answer is $105.

NEED HELP AND HOW U GOT THE ANSWER PLEASE find the measure of the angle greater than BXC using the figure below
Answers
Answer:
m∠BXC = 30°
Step-by-step explanation:
The symbol ∠ means "angle", so "angle ∠BXC" is actually redundant. The "greater than" symbol is "<", which sometimes is used when the proper angle symbol is not available.
Here, the question is simply asking for the measure of angle BXC.
Ray BX crosses the outer, inner scales of the protractor at 40, 140. Ray CX crosses those scales at 70, 110. The measure of angle BXC in degrees is the difference between the numbers on the same scale:
70 -40 = 30 . . . using outer scale numbers
140 -110 = 30 . . . using inner scale numbers
The measure of angle BXC is 30°.

Answers
Answer:
y = 3x-5
Step-by-step explanation:
[tex](-1,-8) = (x_1,y_1) \\ m = 3[/tex]
Substitute values into point slope form
[tex]y - y_1 = m(x - x_1) \\ y - ( - 8)) = 3(x - ( - 1)) \\ y + 8 = 3(x + 1) \\ y + 8 = 3x + 3[/tex]
[tex]y = 3x + 3 - 8 \\ y = 3x - 5[/tex]
Answer:
y=3x-5
Step-by-step explanation:
We are given a point and a slope, so we can use the point-slope formula.
[tex]y-y_{1}=m(x-x_{1})[/tex]
where m is the slope and (x₁, y₁) is the point.
The slope is 3 and the point given is (-1,-8). Therefore,
[tex]m=3 \\x_{1} =-1\\y_{1}=-8[/tex]
Substitute the values into the formula.
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]y--8=3(x- -1)[/tex]
Simplify the signs. Two negative signs become a positive sign.
[tex]y+8=3(x+1)[/tex]
Distribute the 3. Multiply each term inside the parentheses by 3.
[tex]y+8= (3*x)+(3*1)[/tex]
[tex]y+8=3x+3[/tex]
We want to find the equation in slope-intercept form: y=mx+b. Therefore, we must isolate y. 8 is being added to y. The inverse of addition is subtraction. Subtract 8 from both sides.
[tex]y+8-8=3x+3-8[/tex]
[tex]y=3x+3-8[/tex]
[tex]y=3x-5[/tex]
The equation of the line is y=3x-5 ⇒ m= 3, b= -5

infinite solutions
Step-by-step explanation:
1 solution means that only 1 number can replace that variable
No solution means that no numbers can replace that variable. If the 2 sides of the question cannot be solved or they are different, then that equation has no solutions.
Infinite solution means that any number can replace that variable. If the 2 sides of the equation the same, then it is an infinite solution.
6y - 8 = 2(3y - 4)
=> 6y - 8 = 6y - 8
Since both sides of the equations are the same, "y" can be any number.
So, this equation has infinite solutions.

Corbin is helping his grandfather plant the corn in the field. The field covers an area of 43,200 square feet. The length of the field is triple the width. What are the dimensions?
Answers
Answer:
the length is 360 feet and the width is 120 feet.
Step-by-step explanation:
Set up an equation with the area formula, A = lw
The width can be represented by x, and the length can be represented by 3x since it is 3 times the width
43,200 = (3x)(x)
43,200 = 3x²
Solve for x:
14,400 = x²
120 = x
So, the width is 120 feet.
The length is 3 times this, so multiply the width by 3 to find the length
120(3)
= 360
So, the length is 360 feet and the width is 120 feet.
IF nominal alpha is set to .01, which of these p values would be considered criteria for rejecting the null hypothesis?
a. .002
b. .009
c. .04
d. .042
Answers
Answer:
The null hypothesis gets rejected for the p-value of 0.04 and 0.042.
Step-by-step explanation:
We are given the level of significance of [tex]\alpha[/tex] = 0.01 or 1%. And also we are provided with the different p-values.
As we know that; the decision rule for rejecting the null hypothesis is given by;
If the P-value of our test statistics is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.If the P-value of our test statistics is more than the level of significance, then we have insufficient evidence to reject our null hypothesis.(i) The P-value given is 0.002.
Here, the P-value is less than the level of significance as 0.002 < 0.01, then we have sufficient evidence to reject our null hypothesis. So, the null hypothesis gets rejected.
(ii) The P-value given is 0.009.
Here, the P-value is less than the level of significance as 0.009 < 0.01, then we have sufficient evidence to reject our null hypothesis. So, the null hypothesis gets rejected.
(iii) The P-value given is 0.04.
Here, the P-value is more than the level of significance as 0.04 > 0.01, then we have insufficient evidence to reject our null hypothesis. So, the null hypothesis does not get rejected.
(iv) The P-value given is 0.042.
Here, the P-value is more than the level of significance as 0.042 > 0.01, then we have insufficient evidence to reject our null hypothesis. So, the null hypothesis does not get rejected.
