Christine is 4 years younger than Mark. 3 years from now, she will be two-thirds as old as Mark find their present ages.Complete solution
Answer:Mark Is 9 years old; Christine is 5 years old
Step-by-step explanation:
Present age
LET mark age be x
Christine be x-4 yrs
In 3 yrs Time
Mark will be x+3 yrs old
Christine will be (x -4 +3) = x-1 years old
Also, In 3 years time
Christine = 2/3 Mark
such that
x-1 = 2/3(x+3)
x -1= 2x+6 / 3
3x -3= 2x+6
3X--2X = 6+3
=X=9
Mark Is 9 years old
Christine is x -4 = 9-4=5 years old

A quadrilateral has one pair of parallel sides with lengths 134 inches and 114 inches, and two angles that each measure 36°.
Answer:
Explanation:
1) The two parallel sides of different legths 1\frac{3}{4}143 and 1\frac{1}{4}141 constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.

How many solutions does the nonlinear system of equations graphed below have
Answer:
C. two
Step-by-step explanation:
2 points of intersection
Option C is correct, there are two solutions to the nonlinear system of equations graph.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
A system of nonlinear equations is a system of two or more equations in two or more variables containing at least one equation that is not linear.
In this case, we have a parabola (the red figure) and a line (the blue figure).
There are three possible types of solutions for a system of nonlinear equations involving a parabola and a line.
No solution. The line will never intersect the parabola.
One solution. The line is tangent to the parabola and intersects the parabola at exactly one point.
Two solutions. The line crosses on the inside of the parabola and intersects the parabola at two points.
Hence, there are two solutions to the nonlinear system of equations graph.

A company in South Dakota manufactures hard hats used in the mining industry. They record measurements on all the hats they produce for quality control and planning purposes. The measurements they collect include hat size, circumference of the hat, and lengths of the major and minor axes. Meaning, the company wants to predict size of hat given the circumference. What is the response variable
Answer:
Response variable is the hats because it is the variable that is being predicted.
Step-by-step explanation:
A response variable is the subject/variable that responds to the various changes being made in an experiment. For example, if we are testing the effect of some drugs on people's emotions. The response variable here will be "emotions" because it is the subject that responds to the substance of the experiment.
Now, applying that to our question, the size of the hats will be the response variable because it is the variable in the experiment that the company is trying to predict from the circumference.

Answer:
Quintrell's number is 9.
Step-by-step explanation:
Let [tex]x[/tex] be equal to Quintrell's number.
"When 35 is added to my number, the answer is 4 times my original number plus 8."
⇒
[tex]35+x=4x+8[/tex]
Subtract both sides by [tex]x[/tex]
[tex]35+x-x=4x+8-x\\35=3x+8[/tex]
Subtract both sides by 8
[tex]35-8=3x+8-8\\27=3x[/tex]
Divide both sides by 3
[tex]\frac{27}{3} =\frac{3x}{3} \\9=x[/tex]
Therefore, Quintrell's number is 9.

D.
As x increases, f(x) approaches, but never reaches, -1.
E.
The range is all real numbers.
F.
f(x) is positive for all x-values less than 1.
G.
The domain is all real numbers.
Answer:
I need the grahp :)
Step-by-step explanation:
I can at least tell you one thing that all exponential functions have in common, is that G. The domain is all real numbers. I hope this helps :)
All the correct statement are,
B) The y-intercept is 3.
C) The asymptote is y = -1.
G) The domain is all real numbers.
Option B, C and G.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The graph of the exponential function f(x) are shown in figure.
Hence, We get;
The curve intersect the x axis at x = 1.
So, x-intercept is 1.
Hence, Statement A is false.
The curve intersect the y-axis at y= 3.
So, y intercept is 3.
Thus, Statement B is correct.
The curve tends toward infinity at y = -1.
So y = -1 asymptote of the function.
Thus, Statement C is correct.
The range of function is y > -1.
So range is not all real number.
Thus, statement D is incorrect.
The function is defined for x > -0.5. At x = 0.5 function tends toward infinity.
Thus, statement E is incorrect.
As we move from left to right on x-axis then function decreases.
So, The function shows decay.
Hence, The statement F is incorrect.
The value of function approaches -1 as value of x increase but does not cross -1 or touch the value y = -1.
So statement G is correct.
Thus, All the correct statement are,
B, C and G.

g (15 points) Suppose 42 out of 600 rats exposed to a potential carcinogen develop tumors. A control group of 350 rats not exposed to the carcinogen develops 13 tumors. Based on these data, computed (a) the relative risk, (b) the attributable risk, and (c) the odds ratio. Do these indicators suggest that there is a relationship between exposure and tumor risk
Answer:
a) The relative risk is 1.8[tex]\overline{846153}[/tex]
b) The attributable risk is [tex]0.69 \overline{047619}[/tex]
c) There is a relationship between exposure and tumor risk
Step-by-step explanation:
The number of exposed rats that develop tumors, a = 42
The number of rats exposed to the carcinogen = 600 rats
The number of exposed rats that did not develop tumors, b = 600 - 42 = 558
The number of not exposed rats in the control group = 350 rats
The number of rats that develop tumors in the control group, c = 13 tumors
The number of not exposed rats that did not develop tumors, d = 350 - 13 = 337 rats
a) The relative risk, RR = a/(a + b)/(c/(c + d))
∴ RR = (42/(42 + 558))/(13/(13 + 337)) = 49/26 = 1.8[tex]\overline{846153}[/tex]
b) The attributable risk = (a - c)/a
∴ The attributable risk = (42 - 13)/42 = [tex]0.69 \overline{047619}[/tex]
c) The odds ratio = (a·b)/(c·d)
∴ The odds ratio = 42 × 558/(13 × 337) = 23439/4381 ≈ 5.35
Given that the result of attributable risk is positive, there is an indication that there is a higher probability to develop tumor when exposed to the potential carcinogen, therefore, there is a relationship between exposure and tumor risk
