Answer:
1/ 8
Step-by-step explanation:
Given that:
Number of red cards in deck = 26
Number of diamonds in deck = 13
Number of cards in deck = 52
Recall :
Probability = required outcome / Total possible outcomes
Probability of choosing a red :
P(red) = 26 / 52 = 1/2
With replacement :
Probability of diamond :
P(diamond) = 13 / 52 = 1/4
Hence,
Probability of first card red, then second card diamond equals
P(red) * P(diamond)
1/2 * 1/4
= 1/8

Given: LMNK is a parallelogram.
Find x.
N
12x - 2
K
M
22
L X= ?
Answer:
The value of x is 2
Step-by-step explanation:
In the parallelogram, every two opposite sides are equal in lengthsLet us solve the question
In the given figure
∵ LMNK is a parallelogram
∵ ML and NK are opposite sides
→ By using the rule above
∴ ML = NK
∵ ML = 22
∵ NK = 12x - 2
→ Equate them
∴ 12x - 2 = 22
→ Add 2 to both sides
∵ 12x - 2 + 2 = 22 + 2
∴ 12x = 24
→ Divide both sides by 12
∴ x = 2
I have the inequality 120A + 100B <= 220 how do i graph this?
Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
Answer:
See below
Step-by-step explanation:
Given inequality
120a + 100b ≤ 220This is a linear inequality, to graph first find intercepts:
a- intercept, when b = 0
120a = 220a = 220/120 = 1.833b- intercept, when a = 0
100b = 220b = 220/100 = 2.2We got two points:
(1.833, 0) and (0, 2.2)Now graph this with following steps
1. Plot these points on the coordinate plane. 2. Construct a solid line passing through those two points. (it would be dotted line is inequality sigh was > or < )3. Shade the area left to the line. (it would be the area to right if inequality sign was ≥)The graph is attached

3/4 -2 4/5 I NEED HELP ASAP PLS HELP ME
Answer:
-2.05, in fraction form it would be -2 1/20
Answer:
-41/20
Step-by-step explanation:
Hi there!
From the question, I believe you’re asking [tex]\frac{3}{4}[/tex] - [tex]2 \frac{4}{5}[/tex]
First, put the whole number 2 back into the fraction to create an improper fraction.
This would become [tex]\frac{14}{5}[/tex]. Now, we have to find a common denominator between the two fractions. Both 4 and 5 can go into 20, so that will be our common denominator. To turn [tex]\frac{3}{4}[/tex] into a fraction with a denominator of 20, we have to multiply both the numerator and denominator by 5. [tex]\frac{3}{4}[/tex] becomes [tex]\frac{15}{20}[/tex]. We do the same thing for [tex]\frac{14}{5}[/tex] except we multiply the numerator and denominator by 4. We end up with [tex]\frac{56}{20}[/tex]. Now we just have to subtract!
[tex]\frac{15}{20} - \frac{56}{20}[/tex] leaves us with [tex]- \frac{41}{20}[/tex] , which can’t be simplified any further.

What does the 180 mean in this (n-2)180 and why do we multiply it
Answer:
Polygons can be separated into triangles by drawing all the diagonals that can be drawn from one single vertex. If you look back at the formula, you'll see that n – 2 gives the number of triangles in the polygon, and that number is multiplied by 180, the sum of the measures of all the interior angles in a triangle.
