Answer:
a=80° b=40°
Step-by-step explanation:
a=80 (vertically opposite angles )
a+b+90+150 = 360° ( angle sum property of quadrilateral )
80+b+90+150 = 360
b+ 320 = 360
b= 360-320
b=40°

What is the transformation of figure?Transformation of a figure is to change the size, shape or the position of a figure to create a new figure for required use.
The reflection of a plane or shape is flipping the original figure with respect to a reference line. The rule of reflection about x and y-axis is given below,
Reflection about x-axis [tex](x,y)-- > (x,-y)[/tex]Reflection about y-axis [tex](x,y)-- > (-x,y)[/tex]The given figure in the graph is reflected about y-axis. Thus, the rule for the transformation is,

there r 12 fish tanks
each fish tank has 20 quarts
every 10 gallons eqal 1 teaspoon
how many teaspoons for the fish tanks
Answer:
six teaspoons
Step-by-step explanation:
12 fish tanks, each 20 quarts
12x20=240 quarts in 12 tanks
we need to convert quarts to gallons
4 quarts equal one gallon, so
240/4=60 gallons in 12 tanks
60 gallons divided by every 10 gallons equal six teaspoons.

0.4
since 4% and 0.4% are in percentage already
then convert ¼ and 0.4 to percent
¼ to percent = ¼× 100
= 25%
0.4 to percent = 4/10 ×100

This table represents a linear relationship between x and y.
X Y
-6 -3
-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
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/2Given value:
x = 4Therefore,
⇒ y = (4)/2⇒ y = 2Thus, the value of "y" when "x" is 4 is 2.
Scientists claim that a type of insect inherits wing colors in a ratio of 3:3:1 of black, red, and yellow. A 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 approximate P-value for the chi-square goodness of fit test
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
Thus, 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.
