[tex]f(3) =-8[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x + 5; x<1[/tex]

[tex]f(x) =-3x + 1; x >1[/tex]

Required

Determine f(3)

f(3) implies that x = 3.

We make use of

[tex]f(x) =-3x + 1[/tex]

Because x >1 (i.e. 3 > 1)

Substitute 3 for x in f(x) =-3x + 1

[tex]f(3) =-3*3 + 1[/tex]

[tex]f(3) =-9 + 1[/tex]

Answered June 26, 2018

If a+b=8, b+c=10 and c+a=12, what is the value of a+b+c?

The puzzle is solved by defining each variable in terms of another variable & a number & then making substitutions. Begin by taking each sum to define one of the variables in terms of the other. (Different combinations are available, but I’ll follow the a,b,c order.)

a+b=8 becomes a=8-b

b+c=10 becomes b=10-c

c+a=12 becomes c=12-a

Now subtract two of the equations that contain the same variable. I’ll pick two that contain an a: c+a =12 & a+b=8. Subtracting the latter from the former eliminates the “a”s, leaving c-b=4. Adding b to both sides to isolate c gives c=b+4. From above we can take b=10-c to substitute for b in c=b+4, giving us c=(10-c) + 4). Simplify the right side to c=14-c, add c to both sides, giving 2c=14, & then divide both sides by 2 to obtain c=7.

Replace the c in b=10-c with 7 to

There are 18 black and 12 navy socks in your drawer. The room is dark and you
cannot turn on the light. What is the least number of socks that you have to take out of
your drawer to be certain that you have a pair of black socks?

Answers

The least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black.

Given that,

There are 18 black socks and 12 Navy socks in your drawer the room is dark and you cannot turn on the light.

We have to determine

What is the least number of socks that you have to take out of your drawer to be certain that you have a pair of black socks?

According to the question,

The following steps can be used in order to determine the least number of socks that you have to take out of the drawer:

The total number of blue socks is 18,

And the total number of navy socks is 12.

The probability that the socks come out is black socks is,

[tex]\rm P_b = \dfrac{18}{18+12}\\\\P_b= \dfrac{18}{30}\\\\P_b = \dfrac{3}{5}[/tex]

And the probability that the socks come out is navy socks is,

[tex]\rm P_n = \dfrac{12}{18+12}\\\\P_n= \dfrac{12}{30}\\\\P_n = \dfrac{2}{5}[/tex]

On comparing both the probability,

[tex]\rm P_b>P_n[/tex]

Hence, The least number of socks that you have to take out of the drawer to be certain that you have a pair of the same color is 5 and the color is black.

Step-by-step explanation:

We are given that

Total number of cards=52

Number of cards of 4 of spade=1

We have to find the probability of choosing the "4 of spades".

We know that

Probability, P(E)=[tex]\frac{number\;of\;favorable\;cases}{total\;number\;of\;cases}[/tex]

Using the formula

The probability of getting 4 of spade=[tex]\frac{1}{52}[/tex]

Though he makes contact almost every time he swings the bat, he does not strike the mighty blow he sees in his mind. The ball does not leap scalded into the sky, but hops into the tall grass as if startled by a noise; it buzzes mildly, a dying beetle tied to a piece of thread, and rolls to a disappointing stop.3 Uncle Zeno pitches. He tracks the ball into the grass every time the boy hits it, and retrieves it without complaint from each new hiding place. He blames himself for the boys lack of success. The bat is simply too heavy. He knew this for fact when he bought it; he had not wanted to buy a new bat every time the boy grew an inch. He silently chides himself for being cheap.4 Uncle Coran and Uncle Al man the field at improbably optimistic distances behind their brother. Their faces are indistinct in the coming darkness, their forms identical except that Uncle Coran wears a baseball glove on his left hand, while Uncle Al, who is left-handed, wears one on the right. They shout encouragement each time the boy swings the bat. They pound their fists into their gloves, though only for their nephews benefit; their bodies no longer believe the ball will ever make it out to their place in the field. They do not creep closer because it would make the boy feel bad.5 All three of the uncles wear the small, pocketless, old-fashioned baseball gloves they have had since they were boys. Uncle Als mitt was made for a right-handed fielder, but he has worn it on the wrong hand for so long that he no longer notices that it doesnt fit. Each uncle would still gladly play a game of baseball, should anyone ask, although no one has asked for years. They keep their tiny, relic gloves properly oiled, however, as if such invitations were not only commonplace, but imminent.6 The boy studies Uncle Zeno until Uncle Zenos face seems to light up from the inside, weakly, like a moon seen through clouds. It changes into a hundred unfamiliar faces, twists into a hundred strange smiles, until the boy blinks hard and wills his eyes to see only what is there.7 Okay, Doc, Uncle Zeno says. Keep your eye on the ball. Here it comes.8 The baseball in Uncle Zenos hand is almost invisible, a piece of smoke, a shadow. The woods on the far side of the pasture are already dark as sleep; the river twists through them by memory. Uncle Zeno tosses the ball gently toward the boy, who does not see it until its arc carries it above the black line of trees, where it hangs for a moment like an eclipse in the faintly glowing sky. The boy is arm-weary; he swings as hard as he is able. The bat and ball collide weakly. The ball drops to the ground at the boys feet. It lies there stunned, quivering, containing flight beneath its smooth skin. The boy switches the bat into his left hand, picks up the ball with his right, and throws it back to Uncle Zeno.9 I hit it just about every time, the boy says.10 Batter, batter, batter, batter, Uncle Al chirps in the field.11 Say, whatta-say, whatta-say, whatta-say, chants Uncle Coran in the ancient singsong of ballplayers. The uncles are singing to the boy. He has never heard anything so beautiful. He does not want it to stop.12 Okay, Doc, says Uncle Zeno. One more.
