[tex]7x + 1 /16 = 1 /2\\\\7x=1/2-1/16\\\\7x=8-1/16\\\\7x=7/16\\\\x=7/16*7\\\\x=7/112\\\\x=1/16[/tex]

Answer:

n = 10

Step-by-step explanation:

[tex]7 \times 10n = 700 \\ 10n = \frac{700}{7} \\ 10n = 100 \\ \frac{10n}{10} = \frac{100}{10} \\ n = 10[/tex]

Using the binomial distribution, considering the probability of each event, the correct histogram is the fourth one.

For each question, there are only two possible outcomes, either the student guesses the correct answer, or not. The probability of guessing the correct answer on a question is independent of any other question, hence the binomial distribution is used to solve this question.

The formula is:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

In this problem:

Then, the probabilities are as follows:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{5,0}.(0.5)^{0}.(0.5)^{5} = 0.03125[/tex]

[tex]P(X = 1) = C_{5,1}.(0.5)^{1}.(0.5)^{4} = 0.15625[/tex]

[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125[/tex]

[tex]P(X = 3) = C_{5,3}.(0.5)^{3}.(0.5)^{2} = 0.3125[/tex]

[tex]P(X = 4) = C_{5,4}.(0.5)^{4}.(0.5)^{1} = 0.15625[/tex]

[tex]P(X = 5) = C_{5,5}.(0.5)^{5}.(0.5)^{0} = 0.03125[/tex]

Hence the fourth histogram is correct.

The area of a shape is the amount of space it occupies

The area of the rhombus is 24.7 square inches

Start by calculating the length BO using the following Pythagoras theorem

[tex]BC^2 = AO^2 + BO^2[/tex]

So, we have:

[tex]5^2 = 3.8^2 + BO^2[/tex]

Evaluate the exponents

[tex]25 = 14.44 + BO^2[/tex]

Collect like terms

[tex]BO^2 = 25 - 14.44[/tex]

[tex]BO^2 = 10.56[/tex]

Take the square roots

[tex]BO = 3.25[/tex]

The area of the rhombus is then calculated as:

[tex]Area = \frac{2BO * 2AO}{2}[/tex]

This gives

[tex]Area = \frac{2 * 3.25 * 2 * 3.8}{2}[/tex]

[tex]Area = 24.7[/tex]

Hence, the area of the rhombus is 24.7 square inches

Unit price per ounce of the candy of 340.23 grams is $1.58

Ounce and gram are two different unit of mass and relation between them is 1 gram = 0.03527 ounces .

In the question it is given that  weight of candy is 340.23 grams

And it costs $18.99

Now we can covert grams to ounces as

[tex]1 \text{gram}= \ 0.03527 \text{ounces}\\[/tex]

Hence

[tex]340.23 \text{gram}= \ 340.23\times 0.03527 \text{ounces}\\\\\\340.23 \text{gram}=11.99 \ \text{ounces}\\[/tex]

Now 11.99 ounces of candy cost $18.99

So 1 ounce of candy cost 18.99/11.99= $1.58

Unit price per ounce of the candy of 340.23 grams is $1.58

Answer:

A) [tex]\frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]

Step-by-step explanation:

Use implicit differentiation to find dy/dx

[tex]x^2y^2=1\\\\\frac{d}{dx}(x^2y^2)=\frac{d}{dx}(1)\\ \\x^2(\frac{d}{dx}y^2)+(\frac{d}{dx}(x^2))y^2 =0\\\\2yx^2\frac{dy}{dx}+2xy^2=0\\\\2xy(x\frac{dy}{dx}+y)=0\\ \\x\frac{dy}{dx}+y=0\\ \\x\frac{dy}{dx}=-y\\ \\\frac{dy}{dx}=-\frac{y}{x}[/tex]

Determine d²y/dx² using dy/dx

[tex]\frac{dy}{dx}=\frac{-y}{x}\\ \\ \frac{d^2y}{dx^2}=\frac{(x)[\frac{d}{dx}(-y)]-(-y)[\frac{d}{dx}(x)] }{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x\frac{dy}{dx}+y}{x^2}\\ \\ \frac{d^2y}{dx^2}=\frac{-x(\frac{-y}{x})+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{-(-y)+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{y+y}{x^2}\\\\ \frac{d^2y}{dx^2}=\frac{2y}{x^2}[/tex]

Explanation:

The mixed number 8 & 4/5 consists of the whole part 8 and the fractional part 4/5.

Divide the whole part 8 into 4 equal pieces

8/4 = 2

This means 2 is part of the final answer.

Also, divide the 4/5 into 4 equal pieces as well. This is the same as multiplying by 1/4

(1/4)*(4/5) = 1/5

Overall, the size of each section is 2 & 1/5 acres

Three ways I experience these benefits is 1, being able to vote in free elections, 2, being able to receive an education, and 3, being able to volunteer for things.

Step-by-step explanation:

The profit on the shares is $2180

From the question, we have the following parameters that can be used in our computation:

Number of shares = 50

Cost price = $98.40

Current price = $142.00

The profit on the shares is then calculated as

Profit = (Current price - Cost price) * Number of shares

Substitute the known values in the above equation, so, we have the following representation

Profit = (142 - 98.40) * 50

Evaluate

Profit = 2180

Hence, the profit is $2180

Answer:

  24 cm²

Step-by-step explanation:

The rectangular section on the right is 8 - 4 = 4 cm wide.

It is 3 + 1.5 = 4.5 cm tall.

The area of the rectangular section is ...

  A = LW

  A = (4.5 cm)(4 cm) = 18 cm²

__

The triangular section on the left is 4 cm wide and 3 cm high. Its area is ...

  A = 1/2bh

  A = 1/2(4 cm)(3 cm) = 6 cm²

The total shaded area is the sum of the areas of the triangular section and the rectangular section:

  area = 18 cm² +6 cm² = 24 cm² . . . area of the figure

Diagonals of paralleogram bisect eachother

[tex]\\ \rm\longmapsto 5x=30[/tex]

[tex]\\ \rm\longmapsto x=30/5[/tex]

[tex]\\ \rm\longmapsto x=6[/tex]

As we know that, Diagonal of parallelogram bisect each other. That means the two halves of the diagonal are equal. According to this property;

[tex]5x = 30[/tex]

Now, Solve for x by dividing both sides of equation by 5 to eliminate the coefficient of x

[tex]x = 6[/tex]

[tex]5x = 30[/tex]

[tex]5 \times 6 = 30 \\ 30 = 30[/tex]

Step-by-step explanation:

8 times 6 which is how many sides a square has.

20 is the answer.

Step-by-step explanation:

Take a look at the given question,

"75% of what number is 15"

Let's substitute this "what number" as "x"

[tex]75[/tex]%[tex] \times x = 15[/tex]

[tex]→x = \frac{15}{75 \: percent} [/tex]

[tex]→x = \frac{15}{ \frac{75}{100} } [/tex]

[tex]→x = \frac{15}{0.75} [/tex]

To make the denominator as positive for making calculations more easy, we get,

[tex]x = \frac{15 \times 100}{0.75 \times 100} [/tex]

[tex]→x = \frac{1500}{75} [/tex]

Now after doing the division, we get,

[tex]x = 20[/tex]

Hence, 75% of 20 is 15.

x < 4

Step-by-step explanation:

12x - 11 < 37 ( add 11 to both sides )

12x < 48 ( divide both sides by 12 )

x < 4

From the given graph , we see that it passes through the point (0,-1) .

→ y intercept = -1

For finding slope , take another point as (1,3) . Now using the points (1,3) and (0,-1) we can find out the slope as ,

→ m = y2 - y1 / x2 - x1

Substituting the respective values,

→ m = 3 -(-1)/1-0

→ m = 3+1/1

→ m = 4/1

→ m = 4

Hence the slope of the line is 4 and its y intercept is -1 .
