What is a way to write this sentence as an algebraic inequality?

Answers

Answer 1

Answer:

It's C.

Step-by-step explanation:

Did the test

Answer 2

The inequality is y/9 - x > 21.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

x less than the quantity y divided by 9 is more than 21.

Now, writing the mathematical Inequality for the given statement is

x less than the quantity y divided by 9

y/9 -x

and, more than 21.

y/9 - x > 21

Hence, the inequality is y/9 - x > 21.

Although the first quarter of 2002 was quite dismal on Wall Street, mutual funds investing in gold companies rose an average of 35.2%. Assume that the distribution of returns in the first quarter of 2002 for mutual funds specializing in gold companies is fairly symmetrical with a mean of 35.2% and a standard deviation of 20%. If random samples of 16 gold stock funds were selected:

Answers

Complete Question

90% of the sample mean returns are between what two values symmetrically distributed around the mean?

Answer:

The two values symmetrically distributed around the mean are

21.87\% and 43.17\%

Step-by-step explanation:

From the question we are told that

The sample size is [tex]n = 16[/tex]

The sample mean is [tex]\= x = 0.352[/tex]

The standard deviation is [tex]\sigma = 0.20[/tex]

Generally the degree of freedom is mathematically represented as

[tex]df = n -1[/tex]

=> [tex]df = 16 -1[/tex]

=> [tex]df = 15[/tex]

From the question we are told the confidence level is 90% , hence the level of significance is

[tex]\alpha = (100 - 95 ) \%[/tex]

=> [tex]\alpha = 0.10[/tex]

Generally from the t distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of [tex]df = 15[/tex] is

[tex]t_{\frac{\alpha }{2} , 15 } = 2.13 [/tex]

Generally the margin of error is mathematically represented as

[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]

=> [tex]E = 2.13 * \frac{ 0.20 }{\sqrt{16} }[/tex]

=> [tex]E = 0.1065 [/tex]

Generally 90% confidence interval is mathematically represented as

[tex]0.3252 -0.1065 < \mu < 0.3252 + 0.1065 [/tex]

=> [tex]0.2187 < \mu < 0.4317 [/tex]

converting to percentage

[tex]0.2187 * 100 < \mu < 0.4317 * 100 [/tex]

=> [tex] 21.87\% < \mu < 43.17\% [/tex]

Hence the 90% of the sample mean returns are between 21.87\% and 43.17\%

Solve the following quadratic equation
2x²+7x=15

Answers

Answer:

x = - 5 ; x = 3/2

Step-by-step explanation:

Start by subtracting 15 from both sides to get to an equation in standard form: a x^2 + b x + c= 0 so we can use the quadratic formula to solve for "x".

2 x^2 + 7x - 15 = 0

Then:

[tex]x=\frac{-7+/-\sqrt{49-4(2)(-15)} }{4} \\x=\frac{-7+/-\sqrt{169} }{4}\\x=\frac{-7+/-13}{4}\\x =-5\\or\\x=3/2[/tex]

What is the formula for calculating a residual value

Answers

The formula to figure residual value follows: Residual Value = The percent of the cost you are able to recover from the sale of an item x The original cost of the item. For example, if you purchased a $1,000 item and you were able to recover 10% of its cost when you sold it the residual value is $100!!

The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.

In the context of linear regression analysis, the residual value represents the difference between the observed value of the dependent variable and the predicted value. The formula for calculating the residual value can be expressed as:

Residual = Observed Value - Predicted Value

To calculate the residual value, you need to have a regression model that predicts the value of the dependent variable based on the independent variable(s). Once you have the predicted value, you subtract it from the corresponding observed value to obtain the residual.

For example, if you have an observed value of 10 and the predicted value from the regression model is 8, the residual would be:

Residual = 10 - 8 = 2

The residual value indicates how well the regression model fits the observed data, with a residual of zero indicating a perfect fit.
