Answer:

a)= 5 \frac{9}{14}  \\ \\ b) = 7 \frac{1}{2}  \\

Step-by-step explanation:

a)4 \frac{1}{7}  + 1 \frac{1}{2}  \\  \frac{29}{7}  +  \frac{3}{2}  \\  \frac{58 + 21}{14}  \\  =  \frac{79}{14}  \\  = 5 \frac{9}{14}

b)4 \frac{1}{2}  \div  \frac{3}{5}  \\  \frac{9}{2}  \div  \frac{3}{5}  \\  \frac{9}{2}   \times  \frac{5}{3}  \\  =  \frac{45}{6}  \\  =  7 \frac{3}{6}  \\  = 7 \frac{1}{2}

Answer:

5 9/14

7 1/2

Step-by-step explanation:

a) 4 1/7 + 1 1/2= 4+ 1/7 +1 +1/2 = 5 + 1/7 +1/2 = 5+ 2/14 + 7/14= 5 + 9/14= 5 9/14

b) 4 1/2 ÷ 3/5 = 9/2 ÷ 3/5 = 9/2 *5/3= 3/2*5= 15/2= 7 1/2

John makes 35% of his free throw shots.
Minchanka [31]

Answer:

(1)0.39

(2)0.14

(3)0.21

(4)0.26

Step-by-step explanation:

John makes 35% of his free throw shots.

  • The probability that John makes his shot =0.35
  • The probability that John misses his shot =1-0.35=0.65

Sue makes 40% of her free throw shots.

  • The probability that Sue makes her shot =0.4
  • The probability that Sue misses her shot =1-0.4=0.6

(1)John and sue both miss their shots

P(John and sue both miss their shots)

=P(John miss his shot) X P(Sue misses her shot)

=0.65 X 0.6 =0.39

(2)John and Sue both make their shots

P(John and Sue both make their shots)

=P(John makes his shot) X P(Sue makes her shot)

=0.35 X 0.4=0.14

(3)John makes his shot and Sue misses  hers

P(John makes his shot and Sue misses  hers)

=P(John makes his shot) X P(Sue misses her shot)

=0.35 X 0.6=0.21

(4)John misses his shot and Sue makes  hers

P(John misses his shot and Sue makes  hers)

=P(John miss his shot) X P(Sue makes her shot)

=0.65 X 0.4 =0.26

A museum charges $10
Tanzania [10]

A piecewise function is a function that behaves differently in different intervals of its domain.

The piecewise function is:

  • f(x) = $10   if  0 < x < 6
  • f(x) = $15   if  6 ≤ x  ≤ 18
  • f(x) = $20  if 18 < x

<em />

<em>Here the given information for the function is:</em>

  1. The museum charges $10 for kids of 5 and under
  2. The museum charges $15 for ages of 6 to 18
  3. The museum charges $20 for ages larger than 18.

Then if we define x as the age of the person, the function f(x) that tells the <u>cost of the ticket will be:</u>

  • f(x) = $10   if  0 < x < 6
  • f(x) = $15   if  6 ≤ x  ≤ 18
  • f(x) = $20  if 18 < x

So as you can see, depending on the value of x and in which interval it belongs, the function behaves differently.

What is n? Stick around for more points
amm1812

N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7
