Consider a striking deviation as an outlier (Something that stands out in a pattern, EX: 2, 3, 4, 4, 4, 5, 5, 10 where the outlier would be 10.) Because there is a piece of data at 25-30 minutes that deviates (Or, separates, in a way), it would be considered an outlier (Or, a Striking deviation). Using this information, we can conclude that the answer would be A: 25-30 minutes.

First, find the area of the 4 by 16 rectangle. 4 times 16 is 64, so that is the area.

The area of a square is calculated with A = S^2, where A is the area and S is the side length.

So, set 64 to be the area and solve for S. 64 = S^2

The opposite of squaring something is finding the square root. So, find the square root of both sides.

square root of 64 = S

Now, what is the square root of 64? Well, what number when multiplied by itself equals 64? There are actually two possibilities here: -8 and 8. However, -8 cannot be the answer since distance cannot be negative, so 8 is the length of the side.

Answer:

[tex]r=\frac{9\cos \theta}{\sin^2 \theta}[/tex]

Step-by-step explanation:

The given equation in rectangular coordinates is;

[tex]y^2=9x[/tex]

We use the relation;

[tex]x=r\cos \theta[/tex]

and

[tex]y=r \sin \theta[/tex]

This implies that;

[tex](r \sin \theta)^2=9(r \cos \theta)[/tex]

[tex]r^2 \sin^2 \theta=9r \cos \theta[/tex]

Divide through by r to get;

[tex]r \sin^2 \theta=9\cos \theta[/tex]

Divide both sides by [tex]\sin^2 \theta[/tex]

Step-by-step explanation:

16X12.49=199.84

For this case we can raise a rule of three:

x -------------------------> 16 yards

Where the variable "x" represents the cost of the 16 yards.

[tex]x = \frac {16 * 12.49} {1}\\x = 199.84[/tex]

Thus, the cost of the 16 yards will be 199.84 dollars.

Answer:

Option C

The most beneficial banking service for a customer with a new debit card would be no ATM fees, as this would save money on transactions, which is especially important given that banks tend to charge for non-interest income such as ATM and overdraft fees.

For a customer who just obtained a debit card, the most beneficial banking service would be no ATM fees. Debit cards give users the ability to access their funds through an ATM. Considering banks are profit-oriented and look to maximize non-interest income through various fees as described, ATM fees can be a frequent and unnecessary expense. ATM fees average $2.97 per transaction and can quickly accumulate, especially if withdrawals are made at out-of-network ATMs, which add even more to the cost. Therefore, selecting a banking service with no ATM fees would save the cardholder potential costs associated with accessing their money.

No overdraft protection would mean the cardholder could be charged substantial overdraft fees if they were to spend more than the balance in their checking account. Given that these fees can be very high, it's better to either have overdraft protection or manage the account carefully to avoid overdrafting. On the other hand, a $25 yearly fee is a fixed cost and might be worth it if the benefits provided surpass the fee, but it is generally an additional expense that can be avoided with careful account selection. Lastly, 0% financing is typically associated with credit cards rather than debit cards and the quoted 'introductory' rates can be misleading, often coming with hidden fees and high interest rates after the introductory period ends.

Rewrite and make substitution.

EXPLANATION

Since Harriet calculated 27 divided 4 and had 6.75.

This means that:

[tex] \frac{27}{4} = 6.75[/tex]

Now we want to find

[tex] \frac{270}{4} [/tex]

without divide.

Therefore we need to rewrite the expression so in terms of

[tex] \frac{27}{4} [/tex]

so that we can substitute.

This will give us;

[tex] \frac{270}{4} = \frac{27}{4} \times 10[/tex]

This implies that,

[tex]\frac{270}{4} = 6.75 \times 10[/tex]

Now, the easiest way to find 2/3 of a number is to divide that number by 3 and multiply the answer by 2.

192/3=64

64*2=128

Omar kept 128 square centimeters of the flag.

Hope this helps!

[tex] \frac{16 \times 24}{2} = \frac{384}{2} = 192[/tex]

192 is the total area of the triangle; since he kept 2/3 of the flag divide the area by three and times it by two:

[tex]192 \div 3 = 64 \times 2 = 128[/tex]

answer is 128cm^2

Answer:

A)

58/3 = 19.33 hours

B)

84.00 hours

C)

2074.29 miles

Step-by-step explanation:

Under the assumption the earth is a perfect circle, then in a complete rotation ( 24 hours) the earth will rotate through  360 degrees or 2π radians.

A)

In one day or 24 hours the earth rotates through 360 degrees. We are required to determine the duration it takes to rotate through 290 degrees. Let x be the duration it takes the earth to rotate through 290 degrees, then the following proportions hold;

(24/360) = (x/290)

solving for x;

x = (24/360) * 290 = 58/3 = 19.33 hours

B)

In 24 hours the earth rotates through an angle of 2π radians. We are required to determine the duration it will takes the Earth to rotate through 7π radians. Let x be the duration it takes the earth to rotate through 7π radians, then the following proportions hold;

(24/2π radians) = (x/7π radians)

Solving for x;

x = (24/2π radians)*7π radians = 84 hours

C)

If the diameter of the earth is 7920 miles, then in a day or 24 hours a point on the equator will rotate through a distance equal to the circumference of the Earth. Using the formula for the circumference of a circle;

circumference = 2*π*R = π*D

                         = 7920*3.142

                         = 24891.43 miles

Therefore a point on the equator covers a distance of 24891.43 miles in 24 hours. This will imply that the speed of the earth is approximately;

(24891.43miles)/(24 hours) = 1037.14 miles/hr

The distance covered by the point in 2 hours will thus be;

1037.14 * 2 = 2074.29 miles

ANSWER

[tex]p(x) =( x - 3)(2{x} + 1)(x + 2)[/tex]

EXPLANATION

The given polynomial is

[tex]2 {x}^{3} - {x}^{2} - 13x - 6[/tex]

If 3 is a root of this polynomial, then

[tex]x - 3[/tex]

is a factor.

We use long division to obtain the quotient as shown in the attachment.

We can the factor the polynomial as:

[tex]p(x) =( x - 3)(2{x}^{2} + 5x + 2)[/tex]

The complete factored form is:

[tex]p(x) =( x - 3)(2{x} + 1)(x + 2)[/tex]

So what I would do is plug in the point into each system:

#1:

y > 0        (-3,0) since y = 0, plug in 0 for y

0 > 0       This can't be true because they are = to each other, so you would need to have a sign of either ≤ or ≥ (less/greater than or equal to) for the point to be a solution to the system

#2 is the same "0 < 0" can't be true

#3

0 ≤ 0 this is true

y > x + 9     Plug in the point (-3,0)

0 > -3 + 9   Simplify

0 > 6 This is false because 0 is not greater than 6

#4

0 ≥ 0    This is true

0 < -3 + 9

0 < 6     This is true because 0 is less than 6

---->       4th option is your answer

Answer:

(y + 1)

Step-by-step explanation:

Given

5y² + 4y - 1

To factorise the quadratic

Consider the factors of the product of the coefficient of the y² term and the constant term which sum to give the coefficient of the y- term

product = 5 × - 1 = - 5 and sum = + 4

The factors are + 5 and - 1

Use the factors to split the y- term

5y² + 5y - y - 1 ( factor the first/second and third/fourth terms )

= 5y(y + 1) - 1(y + 1) ← factor out (y + 1) from each term

= (y + 1)(5y - 1)

Answer:

Option A.

Step-by-step explanation:

The given sequence is 1.5, 3, 6............

We will check first whether the the given sequence is arithmetic or geometric.

For arithmetic sequence

[tex]a_{2}-a_{1}=3-1.5=1.5[/tex]

[tex]a_{3}-a_{2}=6-3=3[/tex]

1.5 ≠ 3, therefore, the given sequence is not an arithmetic sequence.

For geometric sequence

[tex]\frac{a_{2} }{a_{1} }=\frac{3}{1.5}=2[/tex]

[tex]\frac{a_{3} }{a_{2} }=\frac{6}{3}=2[/tex]

2 = 2, therefore, sequence is geometric.

For geometric sequence explicit formula is defined as

[tex]a_{n}=a_{1}(r)^{n-1}[/tex]

[tex]a_{7}=1.5(r)^{7-1}[/tex]

              = [tex]1.5(2)^{6}=96[/tex]
