Answers

The value of P in the equation (10011 base 2 + P + 11100 base 2 + 101 base 2 = 1001111 base 2) is 11011 base 2.

What is the value of P in the base 2 addition?

The value of P in the equation is found as follows from the given equation:

10011 base 2 + P + 11100 base 2 + 101 base 2 = 1001111 base 2

Hence;

P = 1001111 base 2 - (10011 base 2 + 11100 base 2 + 101 base 2)

Summing the values in the bracket: 10011 + 11100 + 101 = 110100

What is the best graphical representation of the data?

A) The best graphical representatiοn tο display the data wοuld be a histοgram. This is because a histοgram is a bar graph-like representatiοn οf data that grοups a range οf values intο intervals called bins οr classes. The height οf each bar represents the frequency οr number οf data pοints that fall within that bin οr class. A histοgram is an apprοpriate display fοr the data because it shοws the distributiοn οf the grades and allοws fοr easy cοmparisοn οf the frequency οf grades in different ranges.

Part B: Tο create a histοgram οf the data, the steps are as follows:

Step 1: Chοοse a title fοr the histοgram, such as "Distributiοn οf 7th Grade Math Exam Grades".

Step 2: Determine the range οf the data by finding the minimum and maximum values. In this case, the minimum grade is 61 and the maximum grade is 98.

Step 3: Divide the range intο a suitable number οf bins οr classes. A cοmmοn rule οf thumb is tο use between 5 and 20 bins, depending οn the range and distributiοn οf the data. Fοr this data, we can use 10 bins, with a bin width οf 3 (rοunded up frοm 2.9).

Step 4: Label the x-axis with the range οf grades, and label the y-axis with the frequency οr number οf grades.

Step 5: Draw the histοgram by drawing a bar fοr each bin, with the height οf the bar representing the frequency οf grades in that bin. Fοr example, the first bin wοuld be fοr grades between 60 and 62, the secοnd bin wοuld be fοr grades between 63 and 65, and sο οn. Cοunt the number οf grades that fall within each bin, and draw a bar with that height οn the y-axis.

Answers

Answer: B

Explanation:

Start by multiplying both sides of the second equation by -2. Now line up both equations and add them to each other. Since the 2y and -2y cancel out, you are left with -10x = -60. Thus, you get x = 6 and can plug it back in to either equation to solve for y. After that, you are left with the solution (6,3).

maria and joan went shopping. maria bought 3 pair of jeans that each cost the same amount and 4 t-shirts that each cost the same amount. joan bought 2 pair of jeans that each cost the same amount, and 1 t-shirts that each cost the same amount. what is the cost of the jeans and shirts

Answers

Result:

The total cost of the jeans and shirts  = 5(x + y)

How do we determine the cost?

Let's use variables (x and y) to show the total cost of one pair of jeans and one T-shirt, respectively.

Let x = the cost of one pair of jeans.

Let y = e the cost of one T-shirt.

Given:

Maria bought 3 pairs of jeans and 4 T-shirts, all at the same price. That is:

3x = cost of Maria's jeans

4y = cost of Maria's T-shirts

Joan bought 2 pairs of jeans and 1 T-shirt, all at the same price. That is:

2x = cost of Joan's jeans

y = cost of Joan's T-shirt

To find the total cost of all they bought, add up the costs:

Total cost = Maria's cost + Joan's cost

Total cost = 3x + 4y + 2x + y

Total cost = 5x + 5y

So the total cost is 5 times the sum of the cost of one pair of jeans and one T-shirt.

Simplify the expression by factoring out a common factor of 5, and we get:

Therefore, total cost = 5(x + y)

Find all intersection points of the parabola y = x^2 and the circle with a radius √6 and center at (0,4).

Answers

The requried, intersection points are (√5, 5), (-√5, 5), (√2, 2), and (-√2, 2).

To find the intersection points of the parabola y = x² and the circle with radius √6 and center at (0,4), we need to solve the system of equations:

x² + (y - 4)² = 6 (equation of circle)

y = x² (equation of parabola)

We can substitute y = x² into the equation of the circle and obtain a quadratic equation in x:

x² + (x² - 4)² = 6

x⁴ - 7x² + 10 = 0

This equation can be factored as:

(x² - 5)(x² - 2) = 0

Therefore, the solutions for x are x = ±√5 and x = ±√2. To find the corresponding values of y, we can substitute these values of x into the equation of the parabola:

y = x²

For x = √5, we have y = (√5)² = 5, and for x = -√5, we have y = (-√5)² = 5.

For x = √2, we have y = (√2)² = 2, and for x = -√2, we have y = (-√2)² = 2.

How to find the angle of a triangle?

The tangent CD forms a right angle with the radius CT of the circle. This forms a right angle triangle.

Therefore, the sum of angles in the triangle is 180 degrees.

Hence,

∠C = 90 degrees

Therefore,

3x + 14 + 8x + 10 + 90 = 180

11x + 114 = 180

11x = 180 - 114

11x = 66

divide both sides by 11

In one country, it is estimated that in the year 2050, 3% of the population will be over 70 years of age. If the
population of that country in 2050 is 180 million, how many people will be over 70 years old?
A) 3.60 million
(B) 54.00 million
C) 7.20 million
D) 5.40 million

Answers

The expected number of people over 70 years old in that country in 2050 is given as follows:

D) 5.40 million.

How to obtain the expected number of people?

The expected number of people over 70 years old in that country in 2050 is obtained applying the proportions in the context of the problem.

The expected population of that country in 2050 is given as follows:

180 million.

Hence the expected population of the country over 70 years old, equivalent to a percentage of 3%, is obtained as follows:

0.03 x 180 million = 5.4 million.

The missing angle C of the given triangle using law of cosine is: 62.1°

How to use law of cosine?

The Law of Cosines is defined as a numerical formula that relates the side lengths and points of any triangle. It expresses that the square of any side of a triangle is equivalent to the number of squares of the other different sides short two times the result of those sides and the cosine of the point between them.

Numerically, the Law of Cosines can be communicated as:

c² = a² + b² - 2abcos(C),

where c is the length of the side inverse to the point C, and an and b are the lengths of the other different sides.

Thus:

90² = 55² + 50² - 2(55 * 50)cos(C),

2575 = 5500 cos C

2575/5500 = cos C

cos C = 0.4682

C = cos⁻¹0.4682

C = 62.1°

How to calculate the numeric value of a function or of an expression?

To calculate the numeric value of a function or of an expression, we substitute each instance of any variable or unknown on the function by the value at which we want to find the numeric value of the function or of the expression presented in the context of a problem.

The parent function in this problem is given as follows:

f(x) = x².

For the transformation, we want the numeric value of the function at x = 2x, hence:

f(2x) = [2x]²

f(2x) = 4x².

Which is given by option b, representing an horizontal compression by a factor of 1/4 = vertical stretch by a factor of 4 of the graph of the parent function y = x².

Hawa models a can of ground coffee as a right cylinder. She measures its radius as
3/4 in and its volume as 8 cubic inches. Find the height of the can in inches. Round your answer to the nearest tenth if necessary

Answers

Answer: The height is 4.5 in

Step-by-step explanation:

       We can use the given formula for volume, transform it to solve for height (h), and then substitute our given values to solve.

Given formula:

[tex]\displaystyle V=\pi r^2h[/tex]

Transformed to solve for height:

[tex]\displaystyle h=\frac{V}{\pi r^2}[/tex]

Substitute given points:

[tex]\displaystyle h=\frac{(8\; \text{cubic inches})}{\pi (0.75\; \text{inches})^2}[/tex]

Square:

[tex]\displaystyle h=\frac{(8\; \text{cubic inches})}{\pi (0.5625)}[/tex]

Multiply:

[tex]\displaystyle h=\frac{8}{1.767146}[/tex]

Divide:

[tex]\displaystyle h=4.527[/tex]

Round to the nearest tenth:

[tex]\displaystyle h=4.5[/tex]
