find the probability of drawing a diamond 8 through 10 on the first draw, replacing it, and drawing a black card on the second draw?
Drawing an 8, 9 or 10 of diamonds would be 3/52 ( cards out of 52 total cards)
Drawing a black card would be 1/2 ( half the deck is black)
The probability of both happening is 3/52 x 1/2 = 3/104
A coordinate plane. Use the coordinate plane to plot the points (6, 0) and (0, 5). Which statement is true? (0, 5) is located on the x-axis. (0, 5) is located at the origin. (6, 0) is located on the x-axis. (6, 0) is located at the origin.
Hi!
Answer:
C, (6,0) is located on the x-axis.
Step-by-step explanation:
A. is wrong because (0,5) is located on the y-axis because it is going 5 points up, not right
B. and D. are wrong because none of them are located on the origin
That leaves C. and it is right because (6,0) is located on the x-axis

Exponential Equations
We need to recall some properties of exponentials to solve the equations:
[tex]x^a*x^b=x`{a+b}[/tex]
[tex]\displaystyle (x^a)^b=x^{ab}[/tex]
Equation A
[tex]\sqrt{448x^c}=8x^3\sqrt{7x}[/tex]
Squaring:
[tex](\sqrt{448x^c})^2=(8x^3\sqrt{7x})^2[/tex]
Simplifying the radicals:
[tex]448x^c=64x^6(7x)[/tex]
[tex]448x^c=448x^7[/tex]
If follows that
c=7
Equation B
[tex]\sqrt[3]{576x^d}=4x\sqrt[3]{9x^2}[/tex]
Raising to the third power:
[tex](\sqrt[3]{576x^d})^3=(4x\sqrt[3]{9x^2})^3[/tex]
[tex]576x^d=4^3x^3(9x^2)[/tex]
Operating
[tex]576x^d=64x^3(9x^2)=576x^5[/tex]
Thus:
d=5
