What is a quadratic expression?

A quadratic expression is a second-degree algebraic expression represented by the:

[tex]\rm ax^2+bx+c=0[/tex] ........(1)

Where a, b, and c are the constants and  

We have a quadratic expression:

[tex]\rm f(x)=-2x^2+28x+20[/tex]

Convert it to perfect square by perfect square trinomial:

[tex]\rm f(x)=-2(x^2+14x)+20[/tex]  

[tex]\rm f(x)=-2(x^2+14x+49-49)+20[/tex]   (adding and subtracting by 49)

[tex]\rm f(x)=-2(x-7)^2+2(49)+20[/tex]

[tex]\rm f(x)=-2(x-7)^2+118[/tex]

Here [tex]\rm (x-7)^2[/tex] is the positive term and -2 is the negative term so in order to get the highest weekly profit it should be zero, so

[tex]\rm -2(x-7)^2=0[/tex]

x = $7

Thus, the given expression is equivalent to [tex]\rm -2(x-7)^2+118[/tex]  and the price is $7.

Since spring started, Kareem has been surveying the growth of leaves on his neighborhood trees. He goes out every day and computes the average number of leaves on a sample of trees. He created a scatter plot where the y-axis represents the average number of leaves on the trees, and the x-axis represents the number of weeks since spring started. Use the 2 given points to write a linear equation that can be used to approximate the data distribution. ​

Answers

Answer:

y = 1566.67x + 1716.67

is the actual answer..

The linear equation that can be used to approximate the data distribution is y = 1566.67x + 1716.67.

What are Linear Equations?

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Linear equations may include one or more variables.

Given two points on the line.

(0.5, 2500) and (3.5, 7200)

Slope intercept form of a linear equation is y = mx + c, where m is the slope and c is the y intercept.

Slope = (7200 - 2500) / (3.5 - 0.5)

          = 4700 / 3

          = 1566.67

So the equation is, y = 1566.67x + c

Substitute the point (0.5, 2500) to the equation.

2500 = (1566.67 × 0.5) + c

c = 1716.67

So the equation is, y = 1566.67x + 1716.67

Hence the required equation is y = 1566.67x + 1716.67.

the snake slithered 2.25 m before resting on a rock. Then the snake slithered twice as far as it did before, to catch a rat. When the snake headed home he slithered another 90 cm. What was the total distance the snake slithered?

Answers

Answer:

Step-by-step explanation:

2.25m + 2(2.25m) + 90 cm =

2.25m + 4.50m + 90 cm

6.75m + 90 cm

1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m

6.75m + 0.9m = 7.65m <===

2.25m + 2(2.25m) + 90 cm =

2.25m + 4.50m + 90 cm

6.75m + 90 cm

1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m

6.75m + 0.9m = 7.65m

OR../=-

1m = 100 cm....so 7.65m = 7.65 * 100 = 765 cm

SAT math scores for a particular year are normally distributed with a mean of 510 and a standard deviation of 80.

What is the probability that a randomly selected score is greater than 590? Enter the numerical answer only (no percent sign).

Answers

Using the normal distribution, it is found that there is a 16% probability that a randomly selected score is greater than 590.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are, respectively, given by [tex]\mu = 510[/tex] and [tex]\sigma = 80[/tex].

The probability that a randomly selected score is greater than 590 is one subtracted by the p-value of Z when X = 590, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{590 - 510}{80}[/tex]

Z = 1

Z = 1 has a p-value of 0.84.

1 - 0.84 = 0.16.

0.16 = 16% probability that a randomly selected score is greater than 590.

Ex. 1 Write an equation in slope-intercept form for the line that passes through (3, 8) and is
perpendicular to the line with equation y = -1/3x+8

Answers

Answer:

Step-by-step explanation:

The line perpendicual to a reference line will have a slope that is the negative inverse of the reference line.  In this case, the reference line is y= -(1/3)X+8, with a slope of -(1/3).  The negative inverse would be 3.  So the new line would have the form:

y = 3x + b

To find b, the y-intercept, use the given point and solve for b:

y = 3x + b

or 8 = 3*3 + b for the point (3,8)

8=9+b

b= -1

Thje equation of the line perpendicualr to the reference line and going through point (3,8) is:

y = 3x - 1

1. The sample mean weight of 100 chimpanzees was measured to be 82.4 pounds, with a standard deviation of 12.6 pounds. Using a 1% level of significance, what could we claim about the population mean weight for all chimpanzees so that it will fail to be rejected?​

Answers

Using the t-distribution, as we have the standard deviation for the sample, we could claim that the mean weight in pounds is in the interval (79.1, 85.7).

What is a t-distribution confidence interval?

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed 99% confidence interval, with 100 - 1 = 99 df, is t = 2.6259.

The other parameters have values given by:

[tex]\overline{x} = 82.4, s = 12.6, n = 100[/tex].

We could claim that the mean is any value in the 99% confidence interval, which has bounds given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 82.4 - 2.6259\frac{12.6}{\sqrt{100}} = 79.1[/tex]

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 82.4 + 2.6259\frac{12.6}{\sqrt{100}} = 85.7[/tex]

From the linear function formed by the points given in the table, it is found that the x-intercept is of -14.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.

In this problem, when x increases by 20, y decays by 6, hence the slope is given by:

[tex]m = -\frac{6}{20} = -0.3[/tex]

Then:

y = -0.3x + b.

When x = -54, y = 12, hence:

y = -0.3x + b

12 = -0.3(-54) + b.

b = -4.2.

Thus, the equation is:

y = -0.3x - 4.2.

The x-intercept is the value of x when y = 0, hence:

-0.3x - 4.2 = 0.

x = -4.2/0.3

x = -14
