Answer:

\(x = 1.5\) , \(x = 1\)

Explanation:

\(x = \dfrac{ -b \pm \sqrt{b^2 - 4ac}}{2a}\)

equation:  

Here the a = 2 , b = -5 , c = 3

using the equation:

\(\hookrightarrow x = \dfrac{ -(-5) \pm \sqrt{(-5)^2 - 4(2)(3)}}{2(2)}\)

\(\hookrightarrow x = \dfrac{ 5 \pm \sqrt{1}}{4}\)

\(\hookrightarrow x = \dfrac{ 5 +\sqrt{1}}{4}\) , \(x = \dfrac{ 5 -\sqrt{1}}{4}\)

\(\hookrightarrow x = \dfrac{ 5 +1}{4}\) , \(x = \dfrac{ 5 -1}{4}\)

\(\hookrightarrow x = \dfrac{ 6}{4}\)  ,  \(x = \dfrac{ 4}{4}\)

\(\hookrightarrow x = 1.5\) , \(x = 1\)

Answer:

(A) a triangle with a base of 6m and height of 4m:

Area = 1/2 x base x height = 1/2 x 6m x 4m = 12m^2

(B) a parallelogram with a base of 48m and a height of 0.5m:

Area = base x height = 48m x 0.5m = 24m^2

(C) a trapezoid with bases 9m and 3m and height of 4m:

Area = 1/2 x (base1 + base2) x height = 1/2 x (9m + 3m) x 4m = 24m^2

(D) a triangle with a base of 8m and a height of 3m:

Area = 1/2 x base x height = 1/2 x 8m x 3m = 12m^2

So the shapes that have an area of 24 m^2 are A (triangle) and C (trapezoid).

Given the data of the problem, we must answer some questions.

(a) In this problem all the central tendency measures can be computed.

(b) We answer this question by computing the mean, median and mode.

1) For the original set of values, we have:

• The ,mean, is given by the sum of all the data divided by the number of values:

• The ,median, is the data value separating the upper half of a data set from the lower half.

The values 74 and 75 are the values in the middle of the list, the median is the mean of these values:

• The ,mode, is the value or values in the data set that occurs most frequently:

2) For the new set of values, we have:

• The ,mean,:

• The ,median, takes the same value because if we change the first value of the list, the values (74,75) will remain in the center, and the median will be again 74.5.

• The ,mode ,takes the same value because the number 74 will be again the most repeated value in the list.

(c) If we remove the last value of the list, the new measures of central tendency will be:

• The mean is:

• The median is 74 now, because the central value is 74:

• The mode is still 74 because the number 74 remains the most repeated value.

Answers

(a) All of these measures exist.

(b) Mean.

Answer:

The value is \(\mu_{x} = 5.6 \ years\)

Step-by-step explanation:

From the question we are told that

   The population mean is  \(\mu = 5.6 \ years\)

    The standard deviation is  \(\sigma = 0.9 \ years\)

    The sample size is  n  =  49  

Generally given that the sample size is large enough, the  sampling distribution created using the samples of the ages at which 49 children begin reading is equal to the population mean

i.e

     \(\mu_{x} = \mu\)

=>  \(\mu_{x} = 5.6 \ years\)

The answer is:

g(x + 1) = 6x + 1

g(4x) = 24x -5

Work/explanation:

To evaluate, I plug in x + 1 into the function:

\(\sf{g(x)=6x-5}\)

\(\sf{g(x+1)=6(x+1)-5}\)

Simplify

\(\sf{g(x+1)=6x+6-5}\)

\(\sf{g(x+1)=6x+1}\)

------------------

Do the same thing with g(4x)

\(\sf{g(4x)=6(4x)-5}\)

\(\sf{g(4x)=24x-5}\)

Type of rotation of Anticlockwise and clockwise .

A point in coordinate geometry can be rotated through 180 degrees around the origin by drawing an arc with a radius equal to the distance between the provided point's coordinates and the origin, and then extending an angle of 180 degrees at the origin.

The point must be rotated around the origin with regard to its location in the cartesian plane. It is nicely explained in the next part of the 180-degree rotation formula.

The formula for 180-degree rotation of a given value is as follows: if R(x, y) is a point that has to be rotated around the origin, then coordinates of R(x, y) .

The quadratic equation that fits each set of points (0.-8), (2, 0), and (-3, -5) is -3x² + 10x - 8 = 0

Quadratic equation:

Quadratic equation refers algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

Given,

Here we have the set of points (0.-8), (2, 0), and (-3, -5).

Now, we have to find the quadratic equation for this points.

We know that the standard form of the quadratic equation is,

y = ax² +  bx + c

Here we have to use each point value in order to find the value of a, b and c to find the quadratic equation of the points,

First we have to take the point (0, -8) and apply it on the formula, then we get,

-8 = a(0)² +  b(0) + c

-8 = c

Now, use the point (2,0), then we get,

0 = a(2)² +  b(2) + c

0 = 4a + 2b + c --------------------(1)

Finally, take the point (-3, -5), then we get the equations,

-5 = a(-3)² +  b(-3) + c

-5 = 9a - 3b + c --------------------(2)

Now, apply the value of c as -8, then we get,

4a + 2b = 8 ----------------(3)

9a -3b = 3 -----------------(4)

Divide equation (4) by 3 and equation (3) by 2 on both sides then we get,

2a + b = 4

3a - b = 1

When we subtract these equation then we get the value of

a = -3

Then the value of b is

2(-3) + b = 4

b = 4 + 6

b = 10

Therefore, the quadratic equation is -3x² + 10x -8 = 0

Answer by Yi Jing

Step-by-step explanation:

Our vertex has an x-coordinate of 0, so the axis of symmetry for our function is x = 0. Now, let's consider the zeros of our function. Graphically, the zeros of a function are the x-coordinates of the points where the function crosses the x-axis. This occurs where y = 0.

There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.

To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.

Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.

Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.

To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.

Therefore, there will be 12 slices of pizza left over.

To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.

If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.
