Answer:
4. 225
Step-by-step explanation:
The distance between points (-5, -3) and (-5, 12) is the length of the side of the square. Since both points have an x-coordinate of -3, they lie on the same vertical line. The distance between them is |12 - (-3)| = |12 + 3| = |15| = 15. The side measures 15 units.
area = side^2
area = 15^2 = 225
Answer:
225
Step-by-step explanation:
Since the side length of the square is 15 units, a square has sides of the same length, therefore the other side lengths are also 15 units. A = b*h so 15*15=225

why is 6 1/2 equal to the square root of 6
As both of the values are equal to each other.
What is Square root?A square root of a number is a value that, when multiplied by itself, gives the number.
Here, given that,
6^(1/2) and √6
Now, we know that both have same value.
6^(1/2)=√6 ≈2.45
Hence, they are equal.

A box is designed to hold pencils. The front of the box will be made from a clear material for display. The rest of the box will be made from cardboard.
A prism has a length of 20 centimeters, height of 5 centimeters, and width of 4 centimeters.
What is the surface area of the side with the clear material?
Answer:
area of a rectangle/front side of the box = 100 cm²
Step-by-step explanation:
The prism box is a rectangular prism and the front side of the box will be made of the clear material. The other sides will be made of cardboard paper. The surface area of the side with clear material is only the area of the front side of the box. The area of only the front side is the area of 1 rectangle.
The box has a length of 20 cm , height of 5 cm and a width of 4 cm. The surface area of only the front side of the box which is the area of one rectangle only deals with the height and the length.
area of a rectangle/front side = length × height
where
length = 20 cm
height = 5 cm
area of a rectangle/front side = 20 × 5
area of a rectangle/front side = 100 cm²

The probability that an egg on a production line is cracked is 0.01. Two eggs are selected at random from the production line. Find the probability that at least one egg is cracked. Write the entire decimal answer.
Answer:
[tex]P(X \geq 1)=1-P(X<1)= 1- P(X=0)[/tex]
[tex]P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801[/tex]
And replacing we got:
[tex] P(X \geq 1) = 1-0.9801 = 0.0199[/tex]
Step-by-step explanation:
Let X the random variable of interest "number of craked eggs", on this case we now that:
[tex]X \sim Binom(n=2, p=0.01)[/tex]
The probability mass function for the Binomial distribution is given as:
[tex]P(X)=(nCx)(p)^x (1-p)^{n-x}[/tex]
Where (nCx) means combinatory and it's given by this formula:
[tex]nCx=\frac{n!}{(n-x)! x!}[/tex]
And we want to find this probability:
[tex]P(x \geq 1)=1-P(X<1)= 1- P(X=0)[/tex]
And we can find the probability:
[tex]P(X=0)=(2C0)(0.01)^0 (1-0.01)^{2-0}=0.9801[/tex]
And replacing we got:
[tex] P(X \geq 1) = 1-0.9801 = 0.0199[/tex]
The radius of a circle is 4 miles. What is the area of a sector bounded by a 180 arc?
Answer:
The area of sector is [tex]25.12 miles^2[/tex]
Step-by-step explanation:
Radius of circle = 4 miles
We are supposed to find the area of a sector bounded by a 180 arc
[tex]\theta = 180^{\circ}[/tex]
Area of sector =[tex]\frac{\theta}{360^{\circ}} \pi r^2[/tex]
Area of sector = [tex]\frac{180^{\circ}}{360^{\circ}} \times \frac{22}{7} \times 4^2[/tex]
Area of sector = [tex]25.12 miles^2[/tex]
Hence The area of sector is [tex]25.12 miles^2[/tex]
Solve the following problem:
Given: △SAL, SA = LA
AT − ∠bisector
Prove: m∠L = m∠S
Answer:
[tex]\angle L=\angle S[/tex] using congruence rule
Step-by-step explanation:
Given: ΔSAL, SA = LA and AT is the bisector of [tex]\angle A[/tex]
To prove: [tex]\angle L=\angle S[/tex]
Proof:
Two triangles are congruent if they have same shape and same size.
Consider triangles ALT and AST
AL = AS
As AT bisects [tex]\angle A[/tex], [tex]\angle LAT=\angle SAT\\[/tex]
AT = AT (common side)
So, [tex]\Delta ALT\cong \Delta AST[/tex] ( by SAS congruence rule )
Here, SAS denotes side-angle-side
[tex]\angle L=\angle S[/tex] (using corresponding parts of congruent triangles)
Hence proved
Explanation:
First, we know that △ALT ≅ △AST, because of Side Angle Side Theorem. Next, we know that AL ≅ AS, because it's given.
Since A = A, we can remove A and it gives us m∠L = m∠S.
If you need to show work in math terms, your answer should look something like this:
1. △ ALT ≅ △AST - SAS
2. AL ≅ AS - Given
3. m∠ L ≅ m∠S

Are they coterminal
Answer:
no
Step-by-step explanation:
To find coterminal angles for a given angle
add/ subtract 360° from it
Thus
135° + 360° = 495° or 135° - 360° = - 225°

Step-by-step explanation:
Political scientists want to determine the probability of exactly 3 out of the next 5 voters they meet approving a proposal.
If the sample probability of the voters approving the proposal is 50%, the number of trials is and the number of successful trials is .
The probability that 3 out of the next 5 voters approving the proposal is
Answer:
Probability that 3 out of the next 5 voters approving the proposal is 0.3125.
Step-by-step explanation:
We are given that the sample probability of the voters approving the proposal is 50% and Political scientists want to determine the probability of exactly 3 out of the next 5 voters they meet approving a proposal.
The above situation can be represented through binomial distribution;
[tex]P(X=r) = \binom{n}{r} \times p^{r} \times (1-p)^{n-r} ; x = 0,1,2,3,.....[/tex]
where, n = number of trials (samples) taken = 5
r = number of success = exactly 3
p = probability of success which in our question is probability of
the voters approving the proposal, i.e; p = 50%
Let X = Number of voters approving the proposal
So, X ~ Binom(n = 5 , p = 0.50)
Now, Probability that 3 out of the next 5 voters approving the proposal is given by = P(X = 3)
P(X = 3) = [tex]\binom{5}{3} \times 0.50^{3} \times (1-0.50)^{5-3}[/tex]
= [tex]10 \times 0.50^{3} \times 0.50^{2}[/tex]
= 0.3125
y varies directly as x. y=50 when x=5 find y when x=11????
Step-by-step explanation:
given
y is directly to x
to remove directly we use constant let constant be k
y=k x. (1)
let calculate value of k
as it is given
y=50 when x=5
so put in above equation (1)
50=k(5)
50/5=k
10=k
now let find y when x =11
in above equation put the value of x and k
y=10×11
y= 110

Answer:
384 cubic meters
Step-by-step explanation:
Think of it as two rectangles on top of each other and then add the two volumes.
Volume is l*w*h
So for the bottom rectangle: (8) (12) (2) = 192 cubic meters
And for the top rectangle: (4)(6)(8) = 192 cubic meters
It is important to remember that for the top box you have to subtract the height of the bottom box which is why I used 4 for the height instead of 6.
Then you add them together.
192+192 = 384 cubic meters

The volume of this cone is 376.8 cubic feet. What is the radius of this cone?
Use ≈ 3.14 and round your answer to the nearest hundredth
Height is 10ft
Answer:
The radius of the cone is 6 feets.
Step-by-step explanation:
We have,
Volume of the cone is 376.8 cubic feet
Height of the cone is 10 ft
It is required to find the radius of this cone. The formula of the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h[/tex]
r is radius of cone
[tex]r=\sqrt{\dfrac{3V}{\pi h}} \\\\r=\sqrt{\dfrac{3\times 376.8}{3.14\times 10}} \\\\r=6\ ft[/tex]
So, the radius of the cone is 6 feets.

(3x^3-2x^2+4x-8)-(5x^3+12x^2-3x-4)
Answer: [tex]-2x^3-14x^2+7x-4[/tex]
Step-by-step explanation:
[tex](3x^3-2x^2+4x-8)-(5x^3+12x^2-3x-4)[/tex]
Distribute the negative sign.
[tex](3x^3-2x^2+4x-8)-5x^3-12x^2+3x+4[/tex]
Remove the other parentheses.
[tex]3x^3-2x^2+4x-8-5x^3-12x^2+3x+4[/tex]
Combine like terms.
[tex]-2x^3-14x^2+7x-4[/tex]
Select the correct answer. Solve the equation by completing the square. 0 = x2 − 14x A. x = 0, 14 B. x = -56, 42 C. x = -42, 56 D. x = -14, 0
Answer:
A
Step-by-step explanation:
Given
x² - 14x = 0
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 7)x + 49 = 0 + 49
(x - 7)² = 49 ( take the square root of both sides )
x - 7 = ± [tex]\sqrt{49}[/tex] = ± 7 ( add 7 to both sides )
x = 7 ± 7 , thus
x = 7 + 7 = 14 or x = 7 - 7 = 0
