Answer:
B is dependent and A is independent
Step-by-step explanation:
dependent events depend on the outcome or occurrence of the first one. independent is the opposite. it doesn’t have an effect on another event occurring.
it can be kind of confusing but I hope this helped :)

Answer:
Step-by-step explanation:
Use the formula of distance between the two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
1. Distance between A(3, 4) and B(8, 12),
AB = [tex]\sqrt{(8-3)^2+(12-4)^2}[/tex]
AB = [tex]\sqrt{25+64}[/tex]
= [tex]\sqrt{89}[/tex]
≈ 9.43
2. Distance between C(-2, 10) and D(3, -2),
CD = [tex]\sqrt{(3+2)^2+(-2-10)^2}[/tex]
= [tex]\sqrt{25+144}[/tex]
= [tex]\sqrt{169}[/tex]
= 13.00
3. Distance between X(20, 4) and Y(17, 0),
XY = [tex]\sqrt{(20-17)^2+(4-0)^2}[/tex]
= [tex]\sqrt{3^2+4^2}[/tex]
= [tex]\sqrt{25}[/tex]
= 5.00
4. Distance between E(2, -1) and M(6, 9),
EM = [tex]\sqrt{(2-6)^2+(-1-9)^2}[/tex]
= [tex]\sqrt{16+100}[/tex]
= [tex]\sqrt{116}[/tex]
= 10.77
8. Rename the quadratic function f(x) = -2(x + 4)2 - 5 in standard form. A. f(x) = -2x2 + 16x - 37 G. f(x) = -2x2 – 16x + 27 B. f(x) = -2x2 + 16x + 27 D, f(x) = -2x2 – 16x - 37
Answer:
see explanation
Step-by-step explanation:
f(x)= -2(x²+8x+16)-5
[tex] -2 {x}^{2} - 16x - 32 - 5 \\ f(x)= - 2 {x}^{2} - 16x - 37[/tex]
Find the missing side or angle.
Round to the nearest tenth.
B=45°
a=9
c=19
b=[ ]
Answer:
[tex]14.1[/tex]
Step-by-step explanation:
Since we have two sides of a triangle and the angle between them, we can use the Law of Cosines.
For any triangle, the Law of Cosines states:
[tex]b^2=a^2+c^2-2ac\cos B[/tex], where [tex]a[/tex], [tex]b[/tex], and [tex]c[/tex] are all interchangeable.
Substituting given values, we have:
[tex]b^2=9^2+19^2-2(9)(19)\cos 45^{\circ},\\b^2=200.169480834,\\b\approx \boxed{14.1}[/tex]

What is the value of x?
Answer:
x = 5
Step-by-step explanation:
using the Pythagorean theorem:
x² = 13² - 12² = 169 - 144 = 25
x = √25 = 5
Answer:
x = 5.
Step-by-step explanation:
For a right triangle, use the Pythagorean Theorem, a² + b² = c², where a and b are the sides, and c is the hypotenuse.
a² + b² = c²
x²+ 12² = 13²
x² + 144 = 169
Subtract 144 from both sides.
x² = 25
x = 5.
Proof:
a² + b² = c²
5² + 12² = 13²
25 + 144 = 169
169 = 169.

Question 16
Make x the subject of the formula
y = ax2
PLZ HELP MEEE
Answer:
x = ± [tex]\sqrt{\frac{y}{a} }[/tex]
Step-by-step explanation:
Given
y = ax² ( divide both sides by a to isolate x² )
[tex]\frac{y}{a}[/tex] = x² ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{y}{a} }[/tex]
2x-8=x+4. What would x be
[tex]2x - 8 = x + 4[/tex]
Collecting like terms,
[tex]2x - x = 4 + 8[/tex]
Since the signs change when its position changes.
[tex]x = 8 + 4 \\ x = 12[/tex]
Answer:
The value of x would be 12.
Step-by-step explanation:
2x - 8 = x + 4
2x - x = 4 + 8
x = 12
y - 8 = -10
How do I verify the solution ?
Answer:
y = -2
Step-by-step explanation:
SOLUTION :-
Solve the equation.
Add 8 to both sides in order to isolate the equation.[tex]=> y - 8 + 8 = -10 + 8[/tex]
[tex]=> y = -2[/tex]
∴ y = -2
VERIFICATION :-
To verify the solution of y , just put the solution (y = -2) in place of y in equation and check whether L.H.S = R.H.S.
L.H.S :-
-2 - 8 = -10
R.H.S. :-
-10 (already given)
⇒L.H.S. = R.H.S. (verified)

the circumference of a circle is 4π ft. find its diameter in feet
Answer:
4 is the diameter
Step-by-step explanation:
Given:
C = 4π
Formula for circumference:
C = 2πr
Work:
C = 2πr
4π = 2πr
r = (4π)/(2π)
r = 2
Diameter:
d = 2r
d = 2(2)
d = 4
which values are solutions to the inequality -3(x)-4<2
Answer:
x>-2
Step-by-step explanation:
So, lets start by distrubuting the -3 to x:
-3x-4<2
Then lets just start solving. First lets add 4 to both sides to get -3x alone:
-3x<6
Now lets divide -3 from both sides to get x alone:
x<-2
There is one thing we must remember, however.
When dividing a inequality by a negative, the sign is flipped.
So in this case, the < is now >:
x>-2
This basically means a solution is any value greater than -2!
Hope this helps!

The deli gets 1212 -pound blocks of cheese. They slice the cheese into \frac{1}{4} 4 1 - pound and \frac{1}{2} 2 1 - pound packages to sell to customers. How many \frac{1}{2} 2 1 - pound packages of cheese can the deli make with 1212 pounds of cheese?
Answer:
24
Step-by-step explanation:
Based on the question given :
Total pounds of cheese = 12
These cheese are sliced into 1/4 pounds and 1/2 pounds packages.
What the question requests is the number of 1/2 pounds fraction we can get from the total 12 pounds of cheese.
This means we aren't cutting out 1/4 pounds fraction from this package as the question didn't specify.
Hence, the number of 1/2 pounds fraction obtainable from 12 pounds of cheese I s:
We divide the 12 pounds cheese by 1/2
This gives :
12 ÷ 1/2 ; 12 / 1/2
÷ change to multiplication ond the reciprocal of the denominator is used
12 * 2 /1 = 24 /1
We Obtain 24 1/2-pound cheese

10 points. Please don't give a answer that doesn't make sense.
has a y-intercept of (0,2) and passes through the point (3,128)
Answer:
y = 42x + 2
Step-by-step explanation:
The equation of a line is expressed as y = mx+b
Slope = y2-y1/x2-x1
Slope = 128 - 2/3-0
Slope m = 126/3
Slope = 42
Since the y intercept is (0, 2), hence b = 2
Get the equation;
Recall that y = mx+b
y = 42x + 2
This gives the required equation
Daniel drew a toy from a treasure chest containing 30 different toys. He selected a bouncy ball without replacement and then selected a key chain. What is the probability this could occur
Answer:
[tex]Pr = \frac{1}{870}[/tex]
Step-by-step explanation:
Given
[tex]n =30[/tex]
Required
Probability of selecting 2 toys of different types
From the question, we understand that all toys are different i.e. 1 of each type.
And the selection is without replacement;
So, after the first toy is selected; there are n - 1 toys left.
So, the probability is:
[tex]Pr = \frac{1}{n} * \frac{1}{n - 1}[/tex]
Substitute [tex]n =30[/tex]
[tex]Pr = \frac{1}{30} * \frac{1}{30- 1}[/tex]
[tex]Pr = \frac{1}{30} * \frac{1}{29}[/tex]
[tex]Pr = \frac{1}{30*29}[/tex]
[tex]Pr = \frac{1}{870}[/tex]

Answer:
6 runners
Step-by-step explanation:
Complete question
A relay race covers 1 1/2 kilometers, and each runner on a team will run 1/4 of a kilometer. How many runners are needed for a team?
Given that;
1 runner = 1/4 km
If a relay race covers 1 1/2 km, hence;
x runner = 1 1/2 km
Divide both expressions
1/x = (1/4)÷(1 1/2)
1/x = 1/4 ÷ 3/2
1/x = 1/4 * 2/3
1/x = 2/12
Cross multiply
2x = 12
x = 12/2
x = 6
Hence 6 runners are needed for the race

Answer:
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex] = 8
Step-by-step explanation:
The given expression is :
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}[/tex]
We know that,
[tex]\dfrac{1}{x}=x^{-1}[/tex]
So,
[tex](\dfrac{1}{4})^{\dfrac{-3}{2}}=(\dfrac{1}{2^2})^{\dfrac{-3}{2}}\\\\=(2^{-2})^{\dfrac{-3}{2}}\\\\=(2^{-1})^{-3}\\\\=2^3\\\\=8[/tex]
So, the value of the given expression is 8.
