I need an example of ‘what is a 3rd degree polynomial with two terms’ ?

1 answer:

3 0

Answer:Cubic polynomials are polynomials of degree three. Examples include \begin{align*}x^3+8, x^3-4x^2+3x-5\end{align*}, and so on. Notice in these examples, the largest exponent for the variable is three (3). They are all cubics

Researchers examined the bill color (in hue degree) of male and female zebra finches. Here are the summary statistics from the s

sesenic [268]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

In the question some iformation is missing, which can be defined as follows:

Given:

The value of males:

$n_1= 59\\s_1= 1.46\\\bar y_1=2.91\\$

The value of Females:

$n_2=60\\s_2= 2.48\\\bar y_2=7.42\\$

Calculating Degrees of Freedom:

$\bold{ df=\frac{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}{ \frac{1}{n_1-1} (\frac{s_1^2}{n_1})^2+\frac{1}{n_2-1} (\frac{s_2^2}{n_2})^2}}\\\\\\$

$=\frac{(\frac{1.46^2}{59}+\frac{2,48^2}{60})^2}{ \frac{1}{59-1} (\frac{1.46^2}{59})^2+\frac{1}{60-1} (\frac{2.48^2}{60})^2}\\$

$=9.58 or 95$

$\alpha= 1-0.95\\\\$

$= 0.05$

for 95% confidence interval are:

$\frac{\alpha}{2} = \frac{0.05}{2} = 0.025$

From its t-distribution table , the value of t has an region of ( $\frac{\alpha}{2} \ \ 0.025$ ) for (df=95) in its upper tail.

shall be given by = t {0.025}=1.985

Calculating the margin of Error:

$M_OE =t_{0.025} \times \sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2}}$

$=1.985\times \sqrt{\frac{1.46^2}{59}+\frac{2.48^2}{60}}\\\\=0.739$

The difference in mean bill color " $\mu_2 -\mu_1$ " with 95% confidence intervals:

$\to (7.42 - 2.91) \pm 0.739\\\\\to 4.51 \pm 0.739$

Lower limit=3.771

Upper limit = 5.249

balandron [24]

Answer:

Step-by-step explanation:

If sandwiches are 6 dollars each, then chips are 3 dollars, she only bought 5 sandwiches for 6 each for 30 dollars(5*6=30).So, she has 12 dollars left to spend since she spent 42 dollars. And 4 *3=12so she only bought 4 bags of chips.
