Answer:

The zero value of the function occurs at s = 4

Step-by-step explanation:

The given function for the amount of money, m, Jason has left after buying s number of sno-cones for his friend is m = 5 - 1.25·s

Therefore, we have generated from Microsoft Excel the following data table used to plot the points on the graph

Number of Sno-cones          [tex]{}[/tex]        Amount of money left

0                                    [tex]{}[/tex]                        5

1                                    [tex]{}[/tex]                         3.75

2                                    [tex]{}[/tex]                        2.5

3                                    [tex]{}[/tex]                        1.25

4                                    [tex]{}[/tex]                        0

Therefore, as seen from the above table, and from the attached graph, the zero value of the function occurs at the value where the amount of money left (y-coordinate value) is 0 which is at the value of s = 4.

Answer:Therefore Natalie bought   3 water melons  and  10 strawberries

Step-by-step explanation:

Step 1

let watermelons be represented by w

and strawberries be represented by s

Step 2

5w +3s = $45.......eqn 1

w+s=13..........eqn 2

Making w subject of formulae and substituting in equation 2

w= 13-s

5(13-s) + 3s=45

65-5s+3s =45

65-45=5s-3s

20=2s

s=20/2=10

substituting s=10  in equation 2

w +10=13

w= 13-10

w=3

Therefore Natalie bought   3 water melons  and  10 strawberries

Answer:

59%

Step-by-step explanation:

it says there is 200 animal and 82 are cats. we're trying to find the number of dogs. So subtract 82 from 200. that equals 118/200. 118/200 is 59%

If there are 200 animals at the rescue center, the percentage of animals that are dogs is 59%.

Given the following data:

To find the percentage of animals that are dogs:

[tex]Total \;animals = C + D[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]200 = 82 + D\\\\D = 200 - 82[/tex]

Dogs, D = 118 dogs.

Now, we can find the percentage of animals that are dogs:

[tex]Percent = \frac{D}{T}\times 100\\\\Percent = \frac{118}{200}\times 100\\\\Percent = 0.59 \times 100[/tex]

Percent of dogs = 59%

Answer:

Step-by-step explanation:

let the number of children be x

and the number of adults be y

so

12x+3y=162-----1

and

8x+3y=122------2

equating both 1 and 2 we have

12x+3y=162-----1

8x+3y=122------2

subtract 2 from 1 we have

  12x+3y=162-----1

 - 8x+3y=122------2

    4y+0=40

4y=40

y=40/4

y=10

put y=4 in eqn 1 we have

12x+3y=162-----1

12x+3*10=162-----1

12x+30=162

12x=162-30

12x=132

x=132/12  

x=11

therefore a child will cost $11 and adult will cost $10

Answer:

Question 2: D. 604.9

Question 3: 80 oranges or 10/30 or 1/3

Step-by-step explanation:

For question 2:

Okay so, Hal has 5 3/4 bags of munch and each bag covers 105.2 area. We can take the whole number that is already there (5) and multiply it by 105.2 since it is the amount of 1 full bag. So: 5(105.2) is equal to 526.

Now we have to figure out how much 3/4 of a bag is. So take the amount of the full bag and divide it by the denominator (4). So: 105.2/4 is equal to 26.3. Now we know that for 1/4 of a bag it can cover 26.3. We are trying to find the 3/4 so take 1/4 and multiply it by 3 to get 3/4. We can do the same to the amount it is equal with: 26.3(3) and you get 78.9 as an amount of 3/4 of a bag of munch.

Now we add the 3/4 and 5 whole bags: 526.0+78.9=604.9

Our final answer is 604.9 so, option D is correct.

For question 3:

Basically taking all the given fractions: 1/5, 1/6 and 3/10. The lowest amount I can think of is multiplying the denominators to get 30 since they can all equal to 30. So multiply the denominator and numerator for each fraction:

1/5x6=6/30

1/6x5=5/30

3/10x3=9/30

Notice that the denominators are all equal to 30 so this allows us to now add them together.

6/30 + 5/30 + 9/30 = 20/30

Now we know that all together 20/30 is the already know fruits we can easily assume the 10/30 is the amount of oranges. We need to figure out the whole number and not the fraction so, take 240 and divide it by the denominator (30) and we get how much 1/30 is worth in a whole number. So: 240/30=8.

Now we know that 1/30=8 pieces of fruit. Take the 20/30 for already known fruit and we get 160. Take the 10/30 for oranges and we get: 10/30(8) is equal to 80 oranges.

So:

80 oranges

160 other known fruits

Basically 160=2/3 and 80=1/3.

We can check if this is true by:

2/3 (known fruit) and multiply the denominator and numerator by 10 to get 30:

2/3(10)= 20/30. We know this correct because 20/30 is the same as the known fruits fraction we got earlier. Next 1/3(10)=10/30 the 10/30 that was also equal to the amount of oranges.

Our final answer is 80 oranges or 10/30 or 1/3

Step-by-step explanation:

M is the slope and b is the y- intercept. Hope that helps.

A survey found that​ women's heights are normally distributed with mean 64.2 in. and standard deviation 4.2 in. The survey also found that​ men's heights are normally distributed with mean 70.1 in. and standard deviation 4.1 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 57 in. and a maximum of 63 in. Complete parts​ (a) and​ (b) below

a) find the percentage of women meeting the height requirement

b) find the percentage of men meeting the height requirement

Answer:

a

P(57 <  X <  63) = 34.4%

b

P(57 <  X <  63) =  4.096%

Step-by-step explanation:

From the question we are told that

    The mean of women's height is [tex]\mu_ 1 = 64.2[/tex]

    The standard deviation is [tex]\sigma_1 = 4.2 \ in[/tex]

     The mean of men' height is [tex]\mu_2 = 70.1 \ in[/tex]

     The standard deviation of men's height is [tex]\sigma_2 = 4.1 \ in[/tex]

      The minimum height requirement is  a =  57 in

      The maximum height requirement is  b = 63 in

Generally the percentage of women meeting the height requirement  is mathematically represented as

     [tex]P(57 < X < 63) = P(\frac{ 57 - 64.2}{ 4.2} < \frac{X - \mu_1}{\sigma_1} < \frac{ 63 - 64.2}{ 4.2} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

So

      [tex]P(57 < X < 63) = P( -1.7143 < Z <-0.2857)[/tex]

=>  [tex]P(57 < X < 63) = P ( Z <-0.2857) - P(Z < -1.7143)[/tex]

Generally from the z table the probability of  ( Z <-0.2857)  and  (Z <  -1.7143) is  

    P( Z <-0.2857)   =  0.38755

 and

    P(Z <  -1.7143) =  0.043237

So

   P(57 <  X <  63) = 0.38755  - 0.043237

=>  P(57 <  X <  63) = 0.3443

Converting to percentage

     P(57 <  X <  63) = 0.3443  * 100 =  34.4%

Generally the percentage of men meeting the height requirement  is mathematically represented as

     [tex]P(57 < X < 63) = P(\frac{ 57 - 70.1}{ 4.1} < \frac{X - \mu_1}{\sigma_1} < \frac{ 63 - 70.1}{ 4.1} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

So

      P(57 <  X <  63) = P( -3.1951  < Z <-1.7317)

=>  [tex]P(57 < X < 63) = P ( Z <-1.7317) - P(Z < -3.1951)[/tex]

Generally from the z table the probability of  ( Z <-0.2857)  and  (Z <  -1.7143) is  

    P( Z <-1.7317)   =  0.041663

 and

    P(Z <  -3.1951 ) =  0.00069891

So

   P(57 <  X <  63) = 0.041663  - 0.00069891

=>  P(57 <  X <  63) = 0.04096

Converting to percentage

     P(57 <  X <  63) = 0.04096   * 100 =  4.096%

the slope is 15
