Easy

set to zero
those are the roots or xintersepts

(x+1)(x+4)(x-7)=0

x+1=0
x=-1

x+4=0
x=-4

x-7=0
x=7

xints are (-4,0) (-1,0) (7,0)

Answer:

Fourth option is correct. The x-intercepts of the given functions are (-1,0),(-4,0) and (7,0).

Step-by-step explanation:

The given polynomial function is

P(x)=(x+1)(x+4)(x-7)

To find the x-intercepts of the graph of this function, equate the given function equal to zero.

P(x)=0

(x+1)(x+4)(x-7)=0

Using zero product property, equate each factor equal to zero.

x+1=0\Rightarrow x=-1

x+4=0\Rightarrow x=-4

x-7=0\Rightarrow x=7

Therefore the x-intercepts of the given functions are (-1,0),(-4,0) and (7,0). Fourth option is correct.

Arithmetic and geometric series -Find the sum of the first 50 terms of the following series, to the nearest integer.
grandymaker [24]

Answer:

<h3>             10,450</h3>

Step-by-step explanation:

21-13=8   and   29-21=8

So this is aritmetic series where a₁ = 13, and r = 8

Sum of the first n terms:  

S_n=\dfrac{a_1+a_n}{2}\cdot n=\dfrac{a_1+a_1+(n-1)r}{2}\cdot n=\dfrac{2a_1+(n-1)r}{2}\cdot n\\\\\\S_{50}=\dfrac{2\cdot13+(50-1)\cdot8}{2}\cdot50=(13+49\cdot4)\cdot 50=10,450

Which of the following statements is true in a one-way ANOVA? a. The critical value of the test will be a value obtained from th
Musya8 [376]

Answer:

d) All of the above

Step-by-step explanation:

A one way analysis of variance (ANOVA) test, is used to test whether there's a significant difference in the mean of 2 or more population or datasets (minimum of 3 in most cases).

In a one way ANOVA the critical value of the test will be a value obtained from the F-distribution.

In a one way ANOVA, if the null hypothesis is rejected, it may still be possible that two or more of the population means are equal.

This one way test is an omnibus test, it only let us know 2 or more group means are statistically different without being specific. Since we mah have 3 or more groups, using post hoc analysis to check, it may still be possible it may still be possible that two or more of the population means are equal.

The degrees of freedom associated with the sum of squares for treatments is equal to one less than the number of populations.

Let's say we are comparing the means of k population. The degree of freedom would be = k - 1

The correct option here is (d).

All of the above
