Answer: -1 1/2 to -1: -1 1/3 and -5/4

-1 to -1/2: -2/3, -3/4, -6/7, -5/6

-1/2 to 0: -1/3 and -3/8

0 to 1/2: 1/5, 1/10, 3/12, 3/8, 3/7, 1/3

1/2 to 1: 4/5, 6/10, 7/8, 7/9, 3/4, 8/10

1 to 1 1/2: 1 5/12, 9/8

Step-by-step explanation:

Answer:

Step-by-step explanation:

Resolvemos usando la fórmula de puntuación z

z = (x-μ) / σ, donde

x es la puntuación bruta

μ es la media poblacional = 70 kg

σ es la desviación estándar de la población = 3 kg

a) Entre 60 y 75 kg

Para x= 60kg

z = 60 - 70/3 kg

=-3.33333

Valor de probabilidad de la tabla Z:

P(x = 60) = 0.00042906

Para x = 75 kg

z = 75 - 70/3 kg

= 1.66667

Valor de probabilidad de la tabla Z:

P(x = 75) = 0.95221

P(x = 75) - P(60)

0.95221 - 0.00042906

b) Más de 90 kg

Para x> 90 kg

z = 90 - 70/3

= 6.66667

Valor de probabilidad de la tabla Z:

P (x <90) = 1

P (x> 90) = 1 - P (x <90) = 0

Número de árboles = 500

Por tanto, 500 × 0 = 0 árboles

c) Menos de 64 kg

x <64 kg

z = 64 - 70/3 kg

= -2

Valor de probabilidad de Z-Table:

P (x <64) = 0,02275

Hay 500 arboles

= 500 × 0.02275

= 11.375 árboles

D) 64 kilogramos

x = 64 kg

z = 64 - 70/3 kg

= -2

Valor de probabilidad de Z-Table:

P (x = 64) = 0,02275

Hay 500 arboles

= 500 × 0.02275

= 11.375 árboles

Answer:

She lost $15 for three months.

Step-by-step explanation:

Answer: 49+x≤  125, where  x = Amount she can spend more on props.

Now she can spend no more than $76 on props.

Step-by-step explanation:

Given: Lucy can spend no more than $125 on props for a school play.

I.e. Total money she can spend ≤ $ 125

She already purchased costume fabrics that cost $49.

Let x = Amount she can spend more on props.

Required inequality: 49+x≤  125

Subtract 49 from both sides, we get

x≤ 76

Hence, now she can spend no more than $76 on props.

Answer:

Percentage = 91.67%

Step-by-step explanation:

Number of eligible voters = 240,000,000

Number of voters so far = 70,000,000

Number of estimated voters = 150,000,000

Total number of participants (voters) = 70,000,000 + 150,000,000 = 220,000,000

To find the percentage;

[tex] Percentage = \frac {220,000,000}{240,000,000} * 100 [/tex]

[tex] Percentage = \frac {11}{12} * 100 [/tex]

[tex] Percentage = 0.9167 * 100 [/tex]

Percentage = 91.67%

Therefore, the percentage of eligible voters that will participate in this year's election is 91.67%

Answer:

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

Let the number = x

x + x/2 - 20 = 1/4 x

3/2 x - 20 = 1/4x             Multiply by 4

3*2 x - 80 = x

6x - 80 = x

6x - x - 80 = 0

5x - 80 = 0

5x = 80

x = 16

Check

16 + 8 - 20 = 1/4 * 16

24 - 20 = 4

4 = 4

Answer: Elisa

Step-by-step explanation:

Since Elisa withdrew $23 at a time from her bank account and withdrew a total of $207, the number of times that Elisa withdrew will be:

= $207/$23

= 9 times

Since Frances withdrew $43 at a time from his bank account and withdrew a total of $172, the number of times that Frances withdrew will be:

= $172/$43

= 4 times.

Based on the calculations, we can see that Elisa made the greater number of withdrawal.

Answer:

Puppy 1 = 8.6 ounces

Puppy 2 = 9.4 ounces

Puppy 3 = 8.5 ounces

Step-by-step explanation:

Weights of 3 puppies at one week old were

Puppy 1 = 6.5​ ounces

Puppy 2 = 7.3​ ounces

Puppy 3 = 6.4 ounces

Each puppy gained 2.1​ ounces

Puppy 1 = 6.5​ ounces + 2.1 ounces

Puppy 2 = 7.3​ ounces + 2.1 ounces

Puppy 3 = 6.4 ounces + 2.1 ounces

New weight

Puppy 1 = 8.6 ounces

Puppy 2 = 9.4 ounces

Puppy 3 = 8.5 ounces

If the puppies each gained 2.1 ounces, the new weight is given above
