Which is not labeled correctly
Answer:
Step-by-step explanation:
We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.
Let us find probability of getting a club.
Now let us find probability of getting the ace of spades.
Now let us multiply these to find probability of getting a club and ace of spades.
Therefore, probability of getting a club and then the ace of spades .
Answer:
fail 0-x. mid values. =X/2
pass x-a. =(x+a)/2. pass no.=250-35-15-23=177
credit a-y. =(a+y)/2
distinction y-100. =(y+100)/2
mean=1/250*(x/2)×23+(x+a)/2*177+(y+a)/2×35+(y+100)/2×15=64
1/500[23x+177x+177a+35a+35y+15y+100*15)=64
200x+212a+50y+1500=32000
variance=[(X/2-64)^2*23+(x+a,/2-64)^2*277+(a+y/2-64)^2*35+(100+y/2-64)^2*15]/250=(8.6)^2
I've made two equations that has to be simplified.
probably a nother data has to be given since we have 3 variables to solve for(X,a,y)
You need to use a variable.
The height is unknown.
Let h = height.
The base is also unknown, but it is known in terms of the height.
The base is 2/3 the measure of the height.
Since the height is h, the base is 2/3 of h, or (2/3)h.
Now we have an expression for the height, h, and an expression for the base, (2/3)h. We can use the formula for the area of a triangle.
A = bh/2
12 = (2/3)h * h / 2
Now you have an equation in only one variable, h, so you can solve for h.
Once you know h, find the base.
Y=-4x because all you have to do is move the variable to the right by adding its opposite to both sides. So 4x+y-4x=0-4x. Then eliminate the opposites y=0-4x
