Song randomly pulled a marble from a bag, recorded its color, put it back, and repeated. The results are shown in the following table.
Color Frequency
Blue 22
Green 19
Purple 20
Red 18
Yellow 21
If Song were to repeat the experiment 25 more times, how many of those times should he expect to pull a purple marble?
Enter your answer as a number, like this: 42
Step-by-step explanation:
when counting the events we see, he did
22+19+20+18+21 = 100 experiments.
and he got in 20 cases out of the possible 100 a purple marble.
that means the observed probability to pull a purple marble is 20/100 = 1/5.
now he does 25 more pulls.
each with the probity of 1/5 to pull a purple marble.
so, he should expect to pull a purple marble 25×1/5 = 5 times.

use rhombus DEFG if GE=42 and DH=16 find GF
The value of GF in the rhombus is 26.4
Properties of a rhombus:All the sides are equalOpposite angles are equaladjacent angles are supplementaryDiagonals are perpendicular bisector of each otherTherefore,
DH = HF = 16
GH = HE = 21
Using Pythagoras theorem we can find GF as follows:
GF = √21² + 16²GF = √441 + 256
GF = √697
GF = 26.4007575649
GF = 26.4

Peter can mow his lawn in 6 minutes. Peter's son can mow it in 8 minutes. How long will it take them to do it together?
Answer:
3 minutes 26 seconds
Step-by-step explanation:
rate x time in Distance problems, and W = rate x time in work problems. The Work is generally 1, the whole job.
For Peter the formula is 1 (lawn mowed) = 1/6 lawn per minute x 6 minutes.
For the son the formula is 1 = 1/8 * 8.
Add their rates together, 1/8 + 1/6 = 3/24 + 4/24 = 7/24.
The equation for their rate working together is 1 = 7/24 * t
Divide both sides by 7/24 to find t. t = 1 / 7/24 = 1 * 24/7 = 24/7 = 3 and 3/7 minutes = approx. 3 minutes 26 seconds.

-1x-3y=4
2x=16
Answer:
x= 8 y= -4
Step-by-step explanation:2x=16 divide 2 on both, x=8, plug in 8 for x, -1x8-3y=4 will become = -8-3y=4 add 8 on both sides and divide by -3 the answer will be -4
Answer:
Step-by-step explanation:-
-1x - 3y = 4 (eqn 1)
2x = 16 (eqn 2)
from eqn 2
2x = 16
x = 16/2
x = 8
Substitute x = 8 into eqn 1
-1(8) - 3y = 4
-8 - 3y = 4
-3y = 4 + 8
-3y = 12
y = 12/-3
y = -4
therefore, x = 8 and y = -4

What’s the midpoint of a line segment joining the points (5,-4) and(-13,12)?
Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:
((x1 + x2)/2 , (y1 + y2)/2)
((5 + -13) / 2 , (-4 + 12) / 2)
( -8 / 2 , 8 / 2)
(-4 , 4)

PLEASE HELP!! IT'S DUE TONIGHT!
Answer:
Step-by-step explanation:
All triangles without exception, have 3 angles that add to 180o.
You know two of them. The statement above will help you get the third.
35 + 33 + x = 180 Combine the left
68 + x = 180 Subtract 68 from both sides.
x = 180 - 68
x = 112
Answer: The value of x is 112
Step-by-step explanation:
add the two values given: 35+33= 68
then subtract 68 from 180 (sum of angles is 180°) = 112
112+35+33= 180
Consider the function. Which conclusions can be drawn about f–1(x)? Select two options. F–1(x) has a slope of. F–1(x) has a restricted domain. F–1(x) has a y-intercept of (0, –36). F–1(x) has an x-intercept of (–36, 0). F–1(x) has a range of all real numbers.
The required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
Given function
y=f(x) = [tex]-\frac{2}{3} x -24[/tex]
What is an inverse function?An inverse function is a function that returns the original value for which a function has given the output. If f(x) is a function that gives output y, then the inverse function of y, i.e. f-1(y) will return the value x.
In order to get inverse function [tex]f^-1x[/tex] let us arrange the given function
[tex]y+24 = -\frac{2}{3} x[/tex]
[tex]x = -\frac{3}{2} y-36[/tex]
Now, replace x with y and vice versa.
[tex]y = -\frac{3}{2} x -36[/tex]........(1)
or, [tex]f^-1x = -\frac{3}{2} x -36[/tex]
(1) will be the inverse function of the given function.
For x-intercept put y = 0 and for y-intercept put x=0 in eq(1)
x-intercept = -24
y-intercept = -36
The domain and range of f⁻¹x = set of all real numbers since f⁻¹x is a straight line equation, domain, and range of which is set of all real numbers.
Therefore, the required function is [tex]y = -\frac{3}{2} x -36[/tex] having domain and range as R and y-intercept is -36.
