What are the 5 types of problem-solving?

Answer:

  p:q:r = 12:15:10

Step-by-step explanation:

Given p:q = (2/3):(5/6) and q:r = (3/4):(1/2), you want p:q:r.

We can turn each ratio into a ratio of integers by multiplying by the least common denominator.

  p:q = 4:5 . . . . . . . multiply the given ratio by 6

  q:r = 3:2 . . . . . . . multiply the given ratio by 4

Now, we need to have q be represented in each ratio by the same number. That number will be the least common multiple of its representations in these ratios: LCM(5, 3) = 15.

Multiplying the first ratio by 3, we have ...

  p : q = 12 : 15

Multiplying the second ratio by 5 gives ...

  q : r = 15 : 10

Now, we can write the ratio of interest:

  p : q : r = 12 : 15 : 10

Hence option b is the correct option i.e The sample mean's sampling distribution will be roughly normal.

The appropriate response to the question about Sampling Distributions is The sample mean will have a sampling distribution mean that is identical to the population mean.

The sampling distribution must then resemble the normal distribution as the sample size grows.

According to this, if the sample size is large enough, the sampling distribution of the mean will always be normally distributed. The sampling distribution of the mean will be normal regardless of whether the population has a normal, Poisson, binomial, or any other distribution.

A bell-shaped, symmetrical distribution known as a normal distribution has fewer observations the farther out from its center.

Integration by parts, also known as partial integration, is a technique used in calculus and more widely in mathematical analysis to determine the integral of a function's product in terms of the integral of the product of the function's derivative and antiderivative.

The integration of the result of two functions is the integration by parts. Typically, the two functions are shown as f(x) and g. (x). The first function, f(x), is chosen from the two functions in such a way that its derivative formula exists, while the second function, g(x), is chosen in such a way that its integral formula exists.

Answer: 22.5

Step-by-step explanation: To get a percentage of a number you multiply the number you want the percentage of (125), and multiply it by your percent in decimal form. So basically the equation went like this: 125 x 0.18 = 22.5. Another example of this would be if you wanted to find 60 percent of 20. You would just take 60 and put it in decimal form and multiply. 20 x 0.60 = 12. Hope this helps!

Given that segment BD bisects segment AC, the value of x is 5.8 units.

If the corresponding sides and/ or internal angles of two shapes have some  common properties, then it can be said that the shapes are similar. Though similarity does not mean congruency.

Given that segment BD bisects segment AC, the value of x can be determined by comparing the sides of triangles ABD and BCD.

Thus, we have;

x/ 7 = 14/ 17

17x = 7 * 14

     = 98

17x = 98

x = 98/ 17

he system of equations used to represent this scenario is y = –x + 10 and y = 4x, where x and y are the two numbers.

To find the larger number, we can solve the system of equations by setting y = 4x in the first equation and solving for x.

y = –x + 10

4x = –x + 10

3x = 10

x = 10/3

So the smaller number is 10/3. To find the larger number, we know that it is 4 times the smaller number, which is 4(10/3) = 40/3.

Therefore, the larger number is 40/3.

Answer:

The larger number = 8

Step-by-step explanation:

Below is the system of equations:

y = -x + 10

y = 4x

Since both equations equal "y", we can set them equal to each other:

4x = -x + 10

4x + x = 10

5x = 10

x = 2              

This means that at x = 2, the y-values of both equations are the same and is when the criteria of "the sum of two numbers are 10 and the larger number is 4 times the smaller number" is met

"x" is the smaller number. To find the bigger number, input "x" into either one of the equations in the system:

The surface area of the square pyramid is B)61.25[tex]cm^2[/tex]

What is surface area of square pyramid?

The term "square pyramid" also refers to a polyhedron having a square base and four triangular faces. Where the four faces come together is known as the apex. The pyramid's faces connect the base and the tip. The calculation for the square pyramid's surface area adds the areas of the four triangular faces and the base.

Here the given measures are base = 3.5 cm and height = 7cm.

Now using surface area formula then

Surface area of the square pyramid = Base area + 2bl square unit.

Base area = 3.5 × 3.5 = 12.25[tex]cm^2[/tex]

=> Surface area = 12.25+ 2×3.5×7

=> Surface area = 12.25+49

What is the system of equations?

A system of equations is a set of two or more equations that are solved simultaneously. Each equation in the system contains one or more variables, and the goal is to find the values of the variables that satisfy all the equations in the system.

y = -1/6x + 7

y = 2x - 6

To graph the equations y = -1/6x + 7 and y = 2x - 6, we can follow these steps:

Plot the y-intercepts of the equations: The y-intercept is the point where the line crosses the y-axis. For the equation y = -1/6x + 7, the y-intercept is (0,7), and for the equation y = 2x - 6, the y-intercept is (0,-6).

Draw the lines: Starting from the y-intercepts, use the slope of the lines to draw the lines. The slope of the first equation is -1/6 and the slope of the second equation is 2.

Find the x-intercept: The x-intercept is the point where the line crosses the x-axis. For the equation y = -1/6x + 7, the x-intercept is (-42,0) and for the equation y = 2x - 6, the x-intercept is (-3,0)

Locate the point of intersection: The point of intersection of the two lines is the solution of the system of equations. The point of intersection for the given equation is (3,1).

Label the axes and the lines: Label the x- and y-axes, and give the lines descriptive names or equations.

Answer: y = 1/4x +1

Step-by-step explanation:

First, we can find the midpoint of the line segment using the average of x and y coordinates of the endpoints:

M(x,y) = ((-2 + (-6))/2 , (-9 + 7)/2)

M(x,y) = (-4, -1)

To find the slope of the perpendicular bisector, we have to take the negative reciprocal of the slope of the line segment which is (y2-y1)/(x2-x1) = (7-(-9))/(-6-(-2)) = -16/4 = -4

Slope of the perpendicular bisector = -1/slope of the line segment = -1/(-4) = 1/4

Now we can use the point-slope form to find the equation of the line:

y - y1 = m(x - x1)

y - (-1) = 1/4(x + 4)

y = 1/4x +1

so the equation of the perpendicular bisector of the line segment whose endpoints are (-2,-9) and (-6,7) is y = 1/4x +1

Step-by-step explanation:

Remember that the sum of all angles in ANY triangle is 180 degrees. Also, remember that an acute triangle has angles that are all less than 90 degrees. So not only do our options have to add up to 180 degrees, but they also have to be less than 90 degrees in order for the triangle to be acute.

We can immediately exclude options A, B, and C because all three options have angles greater than 90 degrees, which means the triangle isn't acute.

Your answer is option D or "70, 80, 30." Since...

70 + 80 + 30 = 180
70 < 90
80 < 90
30 < 90

By finding the unit rates for the two jars, we will see that the better option is the 28-ounce jar.

To find wich option is the better buy, we need to find the unit rate for each of these jars.

To get the unit rate, we need to take the quotient between the cost of each jar and the volume of peanut butter that each jar has.

We know that the jar of 28 ounces has a cost of $4.29, then its unit rate is:

U =  ($4.29)/28 oz = $0.153 per oz.

This means that with this jar, each ounce costs $0.153

For the 16 ounce jar, the cost is $2.49, then the unit rate is:

U' = $2.49/16 oz = $0.156 per oz.
