Nicole has a pack of playing cards & she chooses a card at random. what is the probability that she picks an ace?
Give your answer as a fraction in its lowest form
Answer:
1/13 (1 in 13)
Step-by-step explanation:
so, there's 4 aces in a standard deck of 52 cards.
so far, we can see this as 4/52 (4 in 52)
these are both divisible by 2, lets go ahead and simplify that to 2/26
still divisible by 2. this then becomes 1 /13
so, she has a 1/13 (1 in 13) chance to get an ace.
detailed explanation and answer please 20 points
Step-by-step explanation:
The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76
So the answer is the bottom one. P=76 and A=330
write and equation of a parabola with the vertex of (0,3) and the focus of (-8,3)
Answer:
(y-3)²= -32x
Step-by-step explanation:
1) the required equation has a form: (y-y₀)²=-2p(x-x₀), where (x₀;y₀) - vertex (0;3), p - parameter of the given parabola;
x₀=0; y₀=3.
2) according to the conditiion F(-8;3)=F(x₀+p/2; y₀), it means (x₀+p/2; y₀)=(p/2;3), then p/2= -8; ⇒ p= -16.
3) finally, p= -16; x₀=0; y₀=3, then it is possible to make up the required equation:
(y-3)²= -32x.
PS/ if it is possible check the suggested solution in other sources.

1. х2 - 3x = 16 solve quadratic
Answer:
[tex]\frac{3+/-i\sqrt{55} }{2}[/tex]
Step-by-step explanation:
[tex]x^2-3x=16[/tex]
Subtract 16 from both sides;
[tex]x^2-3x-16=0[/tex]
[tex]\frac{-(-3)+/-\sqrt{(-3^2)-4(-16)} }{2}=\frac{3+/-\sqrt{9-64} }{2}=\frac{3+/-\sqrt{-55} }{2}=\frac{3+/-\sqrt{55i^2} }{2} =\frac{3+/-i\sqrt{55} }{2}[/tex]

X intercept (slope): [tex](-\frac{7}{2} , 0)[/tex]
Y Intercept: [tex](0, \frac{7}{3} )[/tex]
Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x.
To find the y-intercept, substitute in 0 for x and solve for y.
Hope this helps! :D
Step-by-step explanation:
solve for y
[tex]3y - 7 = 2x[/tex]
isolate the y variable to one side
let's first add 7 to both sides of the equation
[tex]3y - 7 + 7 = 2x + 7[/tex]
sevens on the left side of the equation cancel so we get
[tex]3y = 2x + 7[/tex]
Now let's divide everything in the equation by 3 to further isolate the y variable
[tex] \frac{3y}{3} = \frac{2x}{3} + \frac{7}{3} [/tex]
The threes on the left hand side of the equation cancel
[tex] y = \frac{2}{3}x + \frac{7}{3} [/tex]

The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c.
The given statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c" is absolutely correct.
What is the perimeter?Perimeter is the addition of an external measure of sides it will always positive.
A perimeter is a length and has a degree of the unit as one.
For example
Perimeter of square = side + side + side + side
The perimeter of the circle = πd where d is the dia of the circle.
Given a triangle with sides a,b and c
The perimeter of triangle is = a + b+ c
So,
The perimeter of the triangle is the sum of all sides.
Hence The given statement "The perimeter P of a triangle is equal to the sum of the lengths of sides a, b, and c" is absolutely correct.

Need help on #9 and #10 please ASAP. Was busy with a family emergency and missed my class on this.
Answer:
#9
given, angle BOD = 95 degree
and angle COD = 35 degree
assume that, angle BOC = x degree
so, angle BOC + angle COD = angle BOD
or, x + 35 degree = 95 degree
so, x = 95 degree - 35 degree = 60 degree
so, angle BOC = 60 degree
#10
given, angle AOC = right angle = 90 degree
and angle AOB = 30 degree
assume that, angle BOC = y degree
so, angle AOB + angle BOC = angle AOC
or, 30 degree + y = 90 degree
so, y = 90 degree - 30 degree = 60 degree
so, angle BOC = 60 degree
