The GCF of the terms of the polynomial 52x^8 + 12x^3 is 4x^3.

Step-by-step explanation:

The given expression is

First, we solve the subtraction

Now we subtract 2 on each side to get x-2

Let's solve the difference

Answer:

small = 35 pounds

large = 45 pounds

Step-by-step explanation:

Let x = large boxes

y = small boxes

two equations can be derived from the question

x + y = 80  equation 1

60x + 65y = 4975 equation 2

multiply equation 1 by 60

60x +60y = 4800 equation 3

subtract equation 2 from 3

5y = 175

y = 35

substitute for y in equation 1

x + 35 = 80

x = 80 - 35

x = 45

J in 45min ( bigger hose)

Alternative method

The trick is to convert the numbers you are given to numbers that you can add together.

You have minutes per pool. You can’t work with that. But if you take the reciprocal of each you get pools per minute.

So if the first hose fills 1/55 = 0.01818 pools per minute and the second one fills 1/45 = 0.0222 pools per minute, then both of them will fill 0.1818 + 0.0222 = 0.04040 pools per minute. If we take the reciprocal of that we end up with 1/0.04040 = 24.75 minutes per pool.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of each bag be represented as A

Now , the equation will be

a)

$0.90 for 9 bags of chips

The cost of 9 bags = $ 0.90

The cost of 1 bag A = The cost of 9 bags / 9

Substituting the values in the equation , we get

The cost of 1 bag A = 0.90 / 9

On simplifying the equation , we get

The cost of 1 bag A = $ 0.10

b)

$0.84 for 7 bags of chips

The cost of 7 bags = $ 0.84

The cost of 1 bag A = The cost of 7 bags / 7

Substituting the values in the equation , we get

The cost of 1 bag A = 0.84 / 7

On simplifying the equation , we get

The cost of 1 bag A = $ 0.12

c)

$1.50 for 5 bags of chips

The cost of 5 bags = $ 1.50

The cost of 1 bag A = The cost of 5 bags / 5

Substituting the values in the equation , we get

The cost of 1 bag A = 1.50 / 5

On simplifying the equation , we get

The cost of 1 bag A = $ 0.30

Therefore , the 0.10 < 0.12 < 0.30

Hence , the cost of $0.90 for 9 bags of chips is the best deal

The area of a rectangular patio with the dimensions of 18-3/4 feet and 12 feet will be determined by using the formula for the area of rectangle.

Area of rectangle is calculated by multiplying the length of the rectangle to the width of the rectangle. i.e.,

Area of rectangle= Length*Width

In the given situation,

Length= 18-3/4feet

Width=12 feet.

1. Convert the value of length to improper fraction:

18-3/4=75/4

2. Multiply the length and width to find the area:

Area=(75/4)x12

Solving the expression:

3. Area=75x3=225 sq. feet

So, the probability that the teacher picked teaches a Science subject is approximately 0.4286 or 42.86%.

To find the probability of picking a Science teacher, we need to determine the total number of teachers and the number of Science teachers.

Given that there are 4 Humanities teachers and 3 Science teachers, the total number of teachers is:

Total teachers = 4 + 3 = 7

The number of Science teachers is 3.

Therefore, the probability of picking a Science teacher for promotion is:

Probability = Number of Science teachers / Total teachers

= 3 / 7

Step-by-step explanation:

it is an isoceles triangle (both legs are equally long).

that means also both base angles are equal :

angle J = angle L = 40°

the sum of all angles in a triangle is always 180°.

so,

180 = angle J + angle L + angle K = 40 + 40 + angle K

angle K = 180 - 40 - 40 = 100°

Mean = 0.8

Standard deviation = 2.45

It can be conclude that the probability of selecting more than 30% Beatles songs out of 40 randomly chosen songs is improbable, with only 0.42% of possible outcomes satisfying the condition.

We have, The proportion of the population that belongs to Beatles songs is p = 0.27.

The number of songs played by Paul is n = 40.

Since the value of n is greater than 30, then we can use the normal approximation to the binomial distribution.

The mean of the binomial distribution is

μ = np

⇒ 40 * 0.27 ⇒ 10.8.

The standard deviation of the binomial distribution is

σ = √(npq)

= √(40 * 0.27 * 0.73)

= 2.45.

The probability that more than 30% of the 40 randomly selected songs are Beatles songs, we need to calculate P(X > 0.3n) where X is the number of Beatles songs in the sample.

We use the normal distribution to make the approximation:

z = (0.3n - μ)/σ

= (0.3 * 40 - 10.8)/2.45 ⇒ 2.63.

The probability of getting a z-score of 2.63 or greater is equal to 0.0042.

Hence, the probability that more than 30% of the 40 randomly selected songs are Beatles songs is 0.0042.

Therefore, the conclusion is that the probability of more than 30% of the 40 randomly selected songs being Beatles songs is very low, with only 0.42% of the possible outcomes meeting that condition.

Step-by-step explanation:

Subtract 5 to both sides and then get 12x^2+17x-5=0. Then rewrite the difference for 17x so 20x-3x. Your equation will look like this 12x^2+20x-3-5=0. Now factor 4x out of 12x² ad 20x and get 4x(3x+5). Now factor 3x+5 ad get (4x-1). Now set (3x+5)=0 and (4x-1)=0 and now you will get -5/3 and 1/4.

Answer:

\(x=\{\frac{3\pi}{4}, \frac{7\pi}{4}\}\)

Step-by-step explanation:

For the tangent line to be horizontal, the derivative of the function at that point must be 0.

Thus, let’s first take the derivative of our function:

\(f ^\prime(x)=\frac{d}{dx}[\cos(x)-\sin(x)]\)

Differentiate:

\(f^\prime(x)=-\sin(x)-\cos(x)\)

Now, let’s set our derivative equal to 0:

\(0=-\sin(x)-\cos(x)\)

Let’s multiply everything by a negative:

\(0=\sin(x)+\cos(x)\)

To solve for x, we can subtract sin(x) from both sides. This gives us:

\(\cos(x)=-\sin(x)\)

Now, we can refer to the unit circle. First, remember that the only points for which cosine is equal to sine is at the π/4 points. That is, π/4, 3π/4, 5π/4 or 7π/4.

However, cosine is equal to negative sine. The only two quadrants for which cosine and sine are the same but also have opposite signs is QII and QIV.

Therefore, our answers are 3π/4 and 7π/4.

Answer:

18 gallons from container \(a\) and 22 gallons from the container \(b\) to be mixed to get the required mixture.

Step-by-step explanation:

Given that the container \(a\) has 20% concentrated cleaner

and container \(b\) has pure water which has 0% cleaner.

Let x gallons from container a and y gallons from the container b are mixed to get a 9% concentrated solution.

So,

\(9\%\; \text{of}\; (x+y) = (20\% \; \text{of}\; x )+(0\% \; \text{of}\; y)\cdots(i)\)

As the total amount of the final solution= 40 gallons

So, \(x+y=40\cdots(ii)\)

Using the value of equation (ii) in equation (i), we have

9% of 40 = 20% of x

\(\Rightarrow 0.09\times 40=0.2 \times x\)

\(\Rightarrow x=\frac{0.09\times 40}{0.2}\)

\(\Rightarrow x=18\) gallons.

From equation (ii),

18+y=40

\(\Rightarrow y=40-18=22\) gallons.

Hence, 18 gallons from container \(a\) and 22 gallons from the container \(b\) to be mixed to get the required mixture.

The evidence is not sufficient to support the claim since the p-value is 0.1833 higher than 0.05, so e) none of the preceding.

α = significance level = 0.05

n = sample size

df = degree of freedom = n - 1 = 10 - 1 = 9

Before we find the p-value, we use t test formula. But, before that we calculate mean and standard deviation for two population with excel.

In excel we get,

\(\bar x_1\) = 231.8

\(\bar x_2\) = 214.8

\(\sigma_1\) = 41.95

\(\sigma_2\) = 37.90

Next, we can calculate t test. So,

t = \(\frac{\bar x_1 -\bar x_2}{\sqrt{\frac{\sigma^2_1+\sigma^2_2}{n}}}\)

= \(\frac{231.8-214.8}{\sqrt{\frac{41.95^2+37.9^2}{10}}}\)

= \(\frac{17}{\sqrt\frac{3,196.2125}{10}}\)

= 0.9509

Using t score to p-value calculator for 0.9509, we get p-value = 0.1833.

Thus, the p-value is 0.1833 is higher than significance level 0.05 so there is no sufficient evidence to support the claim.

\(\sf{20\% \times A = 96}\)

\(\sf{ \frac{20}{100} \times A = 96}\)

\(\sf{A = 96 \div \frac{20}{100} }\)

15% of B = 75

\(\sf{15\% \times B = 75}\)

\(\sf{ \frac{15}{100} \times B = 75}\)

\(\sf{B = 75 \div \frac{15}{100} }\)

\(\sf{B = 75 \times \frac{100}{15} }\)

\(\sf{B = \frac{7500}{15} }\)
