Answer:
4x²√4√6√x⁶√x
Step-by-step explanation:
4x²√(24x⁷)
The above expression can be simplified as follow:
4x²√(24x⁷)
Recall
√(MN) = √M × √N = √M√N
Thus,
4x²√(24x⁷) = 4x²√24√x⁷
But:
√24 = √(4×6) = √4√6
√x⁷ = √x⁶√x
Thus,
4x²√24√x⁷ = 4x²√4√6√x⁶√x
Therefore,
4x²√(24x⁷) = 4x²√4√6√x⁶√x

Bob Nale is the owner of Nale's Gas Station. Bob would like to estimate the mean number of gallons of gasoline sold to his customers. He assumes a population standard deviation of 2.30 gallons. From his records, he selects a random sample of 60 sales and finds the mean number of gallons sold is 8.60. What is the z-statistic for a 99% confidence interval for the population mean.
Answer:
The z-statistic for a 99% confidence interval for the population mean is 2.575.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
The z-statistic for a 99% confidence interval for the population mean is 2.575.

Stephanie puts 30 cubes in a box. The cubes are 1 inch on each side. The box holds 2 layers with 15 cubes in each layer. What is the volume of the box?
Step-by-step explanation:
Dimensions of cube = 1 in × 1in .
No. of cubes in each layer = 15 .
No. of layers = 2 .
• Therefore the volume of one cube :-
[tex]\tt \to Volume_{(cube)}= side^3 = (1 \ in.)^3 = \red{1in.^3}[/tex]
• Therefore the volume of one layer :-
[tex]\tt\to 1\ in.^3\times 15 =\orange{15\ in.^3} [/tex]
• Therefore the volume of whole box :-
[tex]\tt\to 2\ in.^3\times 15 =\orange{30\ in.^3} [/tex]
Therefore our required answer is 30 inch ³.
15x2=30 polegadas

Answer:
[tex]A=24[/tex]
Step-by-step explanation:
For finding the area of a trapezoid you first have to use the correct formula which is [tex]A=\frac{1}{2}(b_1+b_2)h[/tex].
Now we plug in what we already know.
[tex]A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)[/tex]
Now we start with the parenthesis
[tex]A=\frac{1}{2}(12)(4)[/tex]
Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally
[tex]A=24[/tex]

The probability that the sum of the two numbers is odd, given that the product is 6 will be 2/3. Option C is correct.
What is probability?Probability is synonymous with possibility. It is concerned with the occurrence of a random event. Probability can only have a value between 0 and 1.
Ethan cranks the arrow on the spinner after rolling the number cube. There is a list of all conceivable outcomes.
{(1, 1), (1, 2), (1,3), (2, 1), (2, 2), (2, 3), (3, 1), (3, 2), (3, 3), (4,1),(4,2), (4,3), (5, 1), (5,2), (5,3), (6, 1), (6,2), (6,3)}
The no of sets having the sum of the number is odd=9
The no of sets having the product of the number is 6=3
The total number including the two conditions=3+9=12
Probability is found as;
P=12/18
P=2/3
The probability that the sum of the two numbers is odd, given that the product is 6 will be 2/3.
Hence, option C is correct.

I need help with angles
Answer:
1. ∠CFD = 28°
2. ∠RPQ = 53°
Step-by-step explanation:
For the first one:
∠CFD and ∠DFE are angles on a straight line
Angles on a straight line add up to equal 180
That being said we can find the missing angle (∠CFD) by subtracting the given angle measure (152°) from 180
so ∠CFD = 180 - 152
180 - 152 = 28
Hence, ∠CFD = 28°
For the second one:
Complementary angles have a sum of 90°
If ∠RPQ and ∠SPR are complementary angles we can find the missing angle ( ∠RPQ in this case ) by subtract the given angle measure ( 37° ) from 90
so ∠RPQ = 90 - 37
90 - 37 = 53
Hence , ∠RPQ = 53°
In ΔOPQ, o = 100 inches, q = 550 inches and ∠Q=67°. Find all possible values of ∠O, to the nearest degree.

which expression represents the area of the trapezoid below? Use the given formula: A= 1/2 (b1 + b2)
Answer:
I think its 5x²-27x+10
Step-by-step explanation:
Area of trapezium:
a+b/2× h
So substitute into the formula:
4x - 1 + 6x - 3 /2 × (x - 5)
1. 4x - 1 + 6x - 3 (collect all like terms)
4x + 6x + -1 -3 = 10x - 4
2. 10x - 4 / 2
= 5x - 2
3. 5x - 2 × x - 5
Use FOIL:
5x ² - 25x - 2x + 10
= 5x ² - 27x +10

Find the volume of a cylinder that has a height of 8 inches and a diameter of 14 inches.
Answer:
[tex]V=1232\ inches^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 8 inches
The diameter of the cylinder, d = 14 inches
Radius, r = 7 inches
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\=\dfrac{22}{7}\times 7^2\times 8\\\\V=1232\ inches^3[/tex]
So, the volume of the cylinder is equal to [tex]1232\ inches^3[/tex].
