3/4

Step-by-step explanation:

the graph point starts at the y-intercept 1 and then moves 4 digits forward and 3 digit upward

Answer:

Since the slope doesn't go down we can safely ignore -3/4 and -4/3.

The slope goes up 3 and 4 to the right.

y = 3

x = 4

y/x

so the answer is 3/4

Answer:

1/6

Step-by-step explanation:

gradient= change in y/ change in x

-4--5/2--4= 1/6

1/6 is the gradient

The gradient of the line segment in its simplest form is: 1/6.

Given the following points, (-4,-5) and (2,-4) are on a line segment:

Gradient (m) = change in y / change in x

Gradient (m) = (-4 -(-5))/(2 -(-4))

Gradient (m) = 1/6

Therefore, the gradient of the line segment in its simplest form is: 1/6.

Answer:

Total cost= $768.66

Step-by-step explanation:

Giving the following information:

Production= 15 units

Standard quantity= 14 pounds per unit

Standard cost= $3.66 per pound

First, we need to calculate the total pounds required to make the hamburgers:

Total pounds= 14*15

Total pounds= 210 pounds

Now, the total cost:

Total cost= 210*3.66

Total cost= $768.66

Answer:

Step-by-step explanation:

[tex]\sqrt{c^2 + c^2 }[/tex] = 9√2

c√2 = 9√2 ⇒ c = 9

b = 2c ⇒ b = 18

d = [tex]\sqrt{18^2 - 9^2 }[/tex] = [tex]\sqrt{(18 - 9)(18+9)}[/tex] = √243 = 9√3

Answer:

The rate of solution change is 2/3 teaspoons per minute

Step-by-step explanation:

Here, we want to calculate rate

From what we have in the question,

68 teaspoons of solution dropped out entirely within 102 minutes

So the rate is takes to drop out per minute will be:

68/102 = 2/3 teaspoon per minute

Given:

A wire 45 meters long is cut into two pieces

One piece is 5 meters longer than the other.

To find:

The length of the two pieces.

Solution:

Let length of one piece be x.

One piece is 5 meters longer than the other. So,

Length of another piece = x+5

Total length of wire is 45. So,

[tex]x+(x+5)=45[/tex]

[tex]2x+5=45[/tex]

Subtract 5 from both sides.

[tex]2x=45-5[/tex]

[tex]2x=40[/tex]

Divide both sides by 2.

[tex]x=\dfrac{40}{2}[/tex]

[tex]x=20[/tex]

Now,

Length of one piece = 20 meters

Length of another piece = 20 + 5

                                        = 25 meters

Therefore, the length of two pieces are 20 and 25 meters.

Answer:

a) 0.04

b) 0.54674

c) 0.10565

d) It is not unusual to have preterm babies

Step-by-step explanation:

The lengths of a particular​ animal's pregnancies are approximately normally​ distributed, with mean, μ = 272 days and standard deviation, σ = 16 days.

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

​(a) What proportion of pregnancies lasts more than 300 ​days?

z = 300 - 272/16

= 1.75

Probability/proportion value from Z-Table:

P(x<300) = 0.95994

P(x>300) = 1 - P(x<300) = 0.040059

Approximately = 0.04

​(b) What proportion of pregnancies lasts between 260 and 284 ​days?

For x = 260 days

z = 260 - 272/16

= -0.75

Probability value from Z-Table:

P(x = 260) = 0.22663

For x = 284

z= 284 - 272/16

= 0.75

Probability value from Z-Table:

P(x = 284) = 0.77337

The proportion of pregnancies lasts between 260 and 284 ​days is

P(x= 284) - P(x = 260)

0.77337 - 0.22663

= 0.54674

​(c) What is the probability that a randomly selected pregnancy lasts no more than 252 ​days?

No more than means less than or equal to, hence, we are to find

P ≤ 252 days

Hence,

z = 252 - 272/16

= -1.25

Probability value from Z-Table:

P(x ≤ 252) = 0.10565

​(d) A​ "very preterm" baby is one whose gestation period is less than 236 days. Are very preterm babies​ unusual?

We find the probability of 236 days

For x = 236

z = 236 - 272/16

z = -2.25

Probability value from Z-Table:

P(x<236) = 0.012224

Converting to percentage = 1.2224%

Hence, it is not unusual to have preterm babies

Answer:

The reason why it helps to have a plan of proof before writing the proof is that the proof plan is the collection of recollected knowledge about the question that will ensure that the required proof is achieved

The proof plan is equivalent to a  virtual construction, consisting of the required parts and how the parts fit together, that obeys or satisfies the actual conditions when the written, step by step on paper

Without a proof plan, the required parts of the proof and therefore how the parts will fit to provide the proof will be absent as well as the non required parts written down to provide a proof without a plan can be confounding

Step-by-step explanation:

Answer:

Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3

Step-by-step explanation:

La densidad de la corona se puede obtener del principio de Arquímedes.

Arquímedes descubrió que la fuerza de empuje hacia arriba sobre un sólido es igual al peso del fluido desplazado. entonces, cuando insertamos la corona en un cilindro de medición con un volumen específico, el volumen de agua desplazado es el volumen de la corona.

Dado que tenemos el volumen de la corona como 300 cm ^ 3 y su masa como 1,5 Kg.

La densidad de la corona = 1500 g / 300 cm ^ 3 = 5 g / cm ^ 3

Esta no es una corona de oro porque la densidad del oro es de 19,3 g / cm ^ 3

Conociendo la masa y el volumen de la corona de Herón, queremos saber si esta estaba hecha de oro o no.

Veremos que los datos proporcionados no coinciden con los que tendría el oro puro.

Sabemos que cada material conocido tiene una dada densidad a una dada temperatura. (Donde densidad es el cociente entre masa y volumen)

Particularmente, sabemos qe el oro tiene una densidad de 19.300 kg/m^3

En este caso, sabemos que la corona tiene una masa de 1.5kg y un volumen de 300cm^3

Notar que las unidades de volumen son diferentes, por lo que devemos cambiarlas:

1m = 100cm

entonces:

1cm = 0.01m

(1cm)^3 = 1cm^3 = (0.01m)^3

Entonces tendremos:

V = 300cm^3 = 0.000001*300 m^3 = 0.0003 m^3

Ahora podemos calcular la densidad como:

D = masa/volumen = 1.5kg/0.0003 m^3 = 5000 kg/m^3

Notar que esto es un tercio de la densidad del oro, asi que no, esto no es oro.
