Answer:
1/45
Step-by-step explanation:
Probability of pulling a red marble is 2/10. If you do not replace the marble, then there are only 9 marbles left in the bag. Assuming you pulled a red marble the first time, this leaves only 1 red marble in the bag. So, the probability of pulling a red marble the second time is 1/9. The probability of pulling two red marbles is (2/10)(1/9) = 1/45
What is the measure of ∠BCE, in degrees, in the figure shown?
Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

What function/equation is best for this
If f(x) = |x| + 9 and g(x) = –6, which describes the range of (f + g)(x)? (f + g)(x) 3 for all values of x (f + g)(x) 3 for all values of x (f + g)(x) 6 for all values of x (f + g)(x) 6 for all values of x
Answer:
The range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]
Step-by-step explanation:
Given
[tex]f(x) = |x| + 9[/tex]
[tex]g(x) = -6[/tex]
Required
Describe the range of [tex](f+g)(x)[/tex]
First, calculate [tex](f+g)(x)[/tex]
[tex](f+g)(x) = f(x) + g(x)[/tex]
Substitute values for f(x) and g(x)
[tex](f+g)(x) = |x| + 9 -6[/tex]
Evaluate Like Terms
[tex](f+g)(x) = |x| + 3[/tex]
The above expression shows that [tex](f + g)(x) \ge 3[/tex]
Because [tex]|x| \ge 0[/tex]
Hence, the range of values of [tex](f + g)(x) \ge 3[/tex] is for all values of x [tex]-\infty[/tex] to [tex]+\infty[/tex]

Solve d=rt for r thanks!!!!
Answer:
Step-by-step explanation:
So you know that distance = rate x time.
9 miles in 1.5 hours
In this case, you know the time (1.5 hours) and the distance (9 miles)
(You can ignore the rest of the chart since the question is just about running.)
What's missing is the rate (r) at which you ran. (Think of it as speed...)
If r x t = d, that means that d ÷ t = r
So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...
6
So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
[tex]y = - 7[/tex]
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7
Hope this helps :)

Solve for j.

+ 7 = -12
=
Answer: j= −17 /3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3j−2+7=−12
3j+−2+7=−12
(3j)+(−2+7)=−12(Combine Like Terms)
3j+5=−12
3j+5=−12
Step 2: Subtract 5 from both sides.
3j+5−5=−12−5
3j=−17
Step 3: Divide both sides by 3.
3j /3 = −17 /3
j= −17 /3
which figure is a translation of Figure A? explain. A translation, or slide, is a transformation that moves every point of a figure the same distance & the same direction.
Answer:
Figure B
Step-by-step explanation:
A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.
A translation would "slide" the figure into a new position without mirroring nor rotating it.
Figure B should be the translation of Figure A.
Hope this helps.
Figure B is the translation of figure A by 2 units up.
What is the transformation of the graph?If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.
For example transformation of graph f(x) by 2 units down.
The new resultant graph could be only translated or rotated or both.
Given figure A
If we look at C then the face of this is towards the right but in figure A the face is towards the left.
So it means C will translate + rotation of graph A it will not be pure translation.
In figure B it is clear that it is a translation of figure A by 2 units upward.
Hence "Figure B is the translation of figure A by 2 units up".

Mason pulled his hamstring while at track practice and received an MRI. His medical bills totaled
$1,200. How much would he have to make in order to pay his bills if he did not use an FSA or HSA?
Answer:
a minimum of $1,200
Step-by-step explanation:
The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

A rectangle with sides measuring x in. and 4x-1 in. has an area of 663in.^2. What are the dimensions of the rectangle?
9514 1404 393
Answer:
13 in by 51 in
Step-by-step explanation:
The area is the product of the dimensions, so is ...
663 = x(4x -1)
4x^2 -x -663 = 0 . . . . . . subtract 663 to put in standard form
Using the quadratic formula, we can find the solutions.
x = (-(-1) ±√((-1)^2 -4(4)(-663)))/(2(4))
x = (1 ± √10609)/8 = (1 ±103)/8
Only the positive solution is of any use in this problem, so ...
x = 104/8 = 13
4x-1 = 4(13)-1 = 51
The dimensions of the rectangle are 13 inches by 51 inches.

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car's average acceleration?
Answer:
Acceleration, [tex]a=4\ m/s^2[/tex]
Step-by-step explanation:
Given that,
Initial speed = 4 m/s at 2 seconds
Final speed = 32 m/s at 9 seconds
We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,
[tex]a=\dfrac{v_2-v_1}{t_2-t_1}\\\\=\dfrac{32-4}{9-2}\\\\=\dfrac{28}{7}\\\\=4\ m/s^2[/tex]
So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].
