What is the value of x2(7−x)+2 when x=5?

Answers

Answer 1
substitute the value of x for 5

(5)^2(7-5)+2

square 5 to get 25(7-5)+2

minus 7 and 5 to get 25(2)+2

multiply 25 and 2 to get 50 + 2

add the equation to get 52

so, the value of the equation is 52

hope this helped!

A circle has a radius 6 inches. If a sector of the circle has an area of 10.8Tt square inches, then what
percent of the circle's area does the sector represent?

Answers

The area of a circle is A = pi • r • r

A = pi • 6 • 6

A = 113.097335529 square inches

To get the percent of the section, divide the section by the whole, and multiply by 100.

10.8/113.097335529 = 9.54929658553%

This table represents a linear relationship between x and y.

-4 -2
-2 -1
0 0
Based on the linear relationship in
this table, what is the value of y when x is 4?

A. 1
B. 2
C. 3
D. 4

Answers

Answer:

y = 2

Step-by-step explanation:

Given table:

[tex]\underline{\ \ \ \ \ \ \ \ \ \ \ \ \ \ } \\\underline{| \ \ \text{x} \ \ | \ \ \text{y} \ \ | } \\ \underline{| \ \text{-6} \ \ | \ \text{-3} \ \ |} \\ | \underline{\ \text{-4} \ \ | \ \text{-2} \ \ | }\\ \underline{| \ \text{-2} \ \ | \ \text{-1} \ \ |} \\ \underline{| \ \ \text{0} \ \ | \ \ 0 \ \ |}[/tex]

To determine the value of y when "x" is 4, we need to determine the equation of the line that represents the table given. Then, we can substitute the value of "x" in the equation to determine the value of y.

Determining the equation of the line that represents the table:

Y-intercept:

Since the coordinate (0, 0) is included in the table, we can tell that the equation of the line that represents the table passes through the origin. Therefore, we can tell that the y-intercept is 0 as the y-intercept is the point on the line that intersects the y-axis.

Slope:

The slope of the line can be determined by picking any two points in the table and substituting the coordinates of the chosen points in the slope formula. Let our chosen points be (-6, -3) and (0, 0).

[tex]\implies \text{Slope} = \dfrac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

[tex]\implies \text{Slope} = \dfrac{0 - (-3) }{0 - (-6) }[/tex]

[tex]\implies \text{Slope} = \dfrac{0 + 3 }{0 + 6 }[/tex]

[tex]\implies \text{Slope} = \dfrac{3}{6} = \dfrac{1}{2}[/tex]

Equation of line:

The equation of the line represented by the table in slope intercept form is y = mx + b, where "m" is the slope and "b" is the y-intercept.

Obtained slope and y-intercept:

Slope = 1/2y-intercept = 0

⇒ y = (1/2)x + 0

⇒ y = x/2

Therefore, the equation of the line is y = x/2.

Determining the value of y when "x" is 4:

Obtained equation of line that represents the table:

⇒ y = x/2

Given value:

x = 4

Therefore,

⇒ y = (4)/2⇒ y = 2

Thus, the value of "y" when "x" is 4 is 2.

The p-value is 0.622 for the sample of this insect was randomly chosen and it was observed that 42 had black wings, 38 had red wings, and 10 had yellow wings.

What is the chi-square test?

A hypothesis testing method is the Chi-square test. Two popular Chi-square tests involve comparing observed and expected frequencies in one or more categories.

The expected proportions are:

3/7, 3/7, 1/7 respectively

Test stasisttics = 0.978

Df = n -1 = 3 - 1 = 2

P-value = 0.622
