Answer:

x=1

Step-by-step explanation:

First we make our equation. Half the books so 1/2 and then 1/3 and 4. So first off they are all postive ( we cant have negative books) and to make the equation we need to find how many books are all together. So 1/2+1/3+4. First combine like terms 1/2+1/3=3/4 then add 3/4 to 4 which is the same as 3/4+4/1= 4 3/4.

<em>Let's solve your equation step-by-step.</em>

Julia is taking a test with multiple choice and true/false question the test has twentg question altogether . julia gets five po
Sonbull [250]
X=number of corect
y=number of incorrect
5 points for each correct so 5x
-1 point for each incorrect so -y

5x-y=76
solve for x and y

I like putting it into slope intercep tofrm which is y=mx+b
add y to both sides
5x=76+y
subtract 76 from both sides
5x-75=y
y=5x-76

subsitute values for x and get values for y
remember, that julia cannot answer a negative number of incorrect questions so y must be greater than or equal to 0

so solve for minimum
0<u><</u>5x-76
add 76 to both sides
76<u><</u>5x
divide by 5
15.2<u><</u>x
you cannot answer a fraction of a correct quesiton so round up
16 is the minumum number of queswtions correctlyh answered


so
x<u>></u>16

subsitute 16 for x
y=5(16)-76
y=80-76
y=4

as we subsitute more numbers over 16, we get these points
so (x,y) 
(16,4)
(17,9)
(18,14)
(19,19)
(20,24)
(21,29)
(22,34)
(23,39)
x=correct answer
y=wrong answers

Cards are selected from a standard deck of 52, the results are recorded in the table. what is the empirical probability of not s
Cerrena [4.2K]

The table have the following results:

 

Hearts – 7

Diamonds – 4

Clubs – 8

Spades – 5

There is a total of 24

 

The question is asking for the probability of not selecting a heart.

So we need to add the probabilities of the diamonds, clubs, and spades since these suits are different from hearts.

So = 4 + 8 + 5 = 17

And we have a total of 24 cards

<span>Therefore the probability is 17/24. </span>
