What’s it the slope of the line

Answers

Answer:

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

The values of the Ferris wheel.

The Ferris wheel is a ride that is fired by the upright rotating wheel and is able of carrying multiple passengers. The table shows us the value of the height of a car of the Ferris wheel and as it travels in a circular motion. The time and height of the second and meters are given.

Thus the answer is if the car is loaded at 0 s, then people are at the lowest part.

The wheel data shows that in 2 seconds the height of the wheel is about 26 meters and in 16 seconds the height of the wheel is about 6 meters. Thus the car is located at 0s and people are at the lowest height of the wheel.Hence the option C is correct.

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. ​(a) What proportion of pregnancies lasts more than 300 ​days? ​(b) What proportion of pregnancies lasts between 260 and 284 ​days? ​(c) What is the probability that a randomly selected pregnancy lasts no more than 252 ​days? ​(d) A​ "very preterm" baby is one whose gestation period is less than 236 days. Are very preterm babies​ unusual?

Answers

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

Kyle plans to make 15 hamburger patties, each weighing 14 pound, for a cookout. At the store, hamburger meat is priced at $3.66 per pound. If Kyle orders the exact amount of meat he needs, how much will it cost, rounded to the nearest cent?

Answers

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

Sally spent a long time searching for the perfect tree. She could look in 6 stores in 45 minutes. If she shopped for 2 hours, how many stores did she visit?

Answers

Answer:

24

Step-by-step explanation:

Sally visited 16 stores when shopping for 2 hours.

Since Sally could look in 6 stores in 45 minutes. Hence:

Time spent in each store = 45 minutes/6 stores = 7.5 minutes per store.

Given a time of 2 hours = 2 hours * 60 minutes per hour = 120 minutes

Number of stores visited in 2 hours = 120 minute / 7.5 minute per store = 16 stores

Therefore Sally visited 16 stores in 2 hours.

An art teacher has 28 students in her first-period class and 24 students in her second-period class. If almost 30% of the students in these classes are boys, about how many boys are in her first two classes?
A. 36
B. 15
C. 8
D. 7

Answers

Answer:
C. 8


Explanation:
One way to solve this is to find 30% of each class, 28 and 24.

30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2

You can then find the average of these two numbers.

8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8

Another way to solve is to first find the average number of people in each class.

28 + 24 = 52
52 ➗ 2 = 26

You can then find 30% of this number.

26 • 0.30 = 7.8
7.8 rounds up to 8

What survival rate in the 10th year would make the average

Step-by-step explanation:

please find the complete question in the attached file.

Time= 10 year =38.0%

let,  

x=rate

[tex]\to 38 = \frac{(36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x)}{10}[/tex]

[tex]\to 38 = \frac{(343 + x )}{10}\\\\\to 380 = (343 + x )\\\\\to 380 - 343 = x \\\\\to x= 37\%[/tex]

The rate of survival differs from the rate of loss, meaning the rate of survival were:

[tex]= 1 - loss\ rate \\\\= 1 - 37\% \\\\= 1 - \frac{37}{100} \\\\= \frac{100-37}{100} \\\\= \frac{63}{100} \\\\=63 \%[/tex]

La Corona que herón mando elaborar tenía una masa de 1.5 kg y ocupaba un volumen de 300 cm ¿Era de oro dicha Corona? (Obten la respuesta utilizando el principio de arquímedes)

Answers

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.

Circle A has a diameter of approximately 20 inches and an area of approximately an area of 300 in² Circle B has a diameter of approximately 60 inches Which of these could be the area of circle B? A. About 100 in^2 B. About 300 in^2 C. About 900 in^2 D. About 2700 in^2

Answers

Answer:

D. About 2700 in^2

Step-by-step explanation:

The area of a circle A = πd²/4 where d = diameter of circle.

A/d² = π/4 = k the proportionality constant.

So, A₁/d₁² = A₂/d₂² Now for circle A, Area = A₁ = 300 in² and diameter = d₁ = 20 inches. For circle B, Area = A₂ = unknown and diameter = d₂ = 60 inches.

So, we have

A₁/d₁² = A₂/d₂²

A₂ = A₁d₂²/d₁²

A₂ = A₁(d₂/d₁)²

substituting the values of the variables, we have

A₂ = 300 in²(60 in/20 in)²

A₂ = 300 in²(3)²

A₂ = 300 in²(9)

A₂ = 2700 in²

So, the area of circle B is about 2700 in²

Answers

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
