Answer:
It's B
Step-by-step explanation:
Multiple the denominator with the whole number, then take that number and add it with the numerator. So you'll have 12/5 x 19/4. Multiply the numerators with each other and the denominators with each other and you'll have 228/20. Divide 228 by 4 and you'll get 11 2/5.
Que pase por el punto ( 2 , 3 ) y es perpendicular a la recta x − 4 y + 1 = 0
Answer:
y = -4x+11
Step-by-step explanation:
x − 4 y + 1 = 0
x+1 = 4y
4y = x+1
y = 1/4x+1/4
pendiente de una recta perpendicular es el recíproco negativo
negative reciprocal 1/4x is -4x
y = -4x+1/4
Con la nueva pendiente, use la forma de intersección de la pendiente y el punto para calcular la intersección usando (2,3) :
y = mx + b or y = -4x+b
3 = -4(2) + b
3 = -8 + b
11 = b
b = 11
y = -4x+11

1. Mrs. Galicia is building a chicken farm in 2021 with an initial population of 3750 chickens. The farm grows at a rate of 2.15% annually. (a) Use the exponential growth model to write an equation that estimates the population t years after 2021. (b) Estimate the population of the town in 2036.
show plug in step before using calculator Answer:
The population of the chicken after 15 years in 2036 will be 5177.
What is an exponential growth model?The exponential growth model is given by the equation, [tex]y=y_oe^{rt}[/tex], where y is the population after t years, y₀ is the initial population, r is the rate of growth, and t is the time.
As it is given that the initial chicken population in the year 2021 is 3750, while the rate at which the population is increasing is 2.15% annually.
A.) The exponential growth model to write an equation that estimates the population t years after 2021.
The exponential growth model can be written as,
[tex]y=y_oe^{rt}\\\\y=3750e^{0.0215t}[/tex]
B.) The population of the town in 2036,
As the population is increasing for the next 15 years(2036-2021). Therefore, The population of the town in 2036 can be written as,
[tex]y=3750e^{0.0215t}\\\\y=3750e^{0.0215\times 15}\\\\y= 5177.1558\approx 5177[/tex]
Hence, the population of the chicken after 15 years in 2036 will be 5177.

Arrange the children in ascending order of their weights.
Nayana : 28.76 kg
Aman:32.63 kg
Asif: 32.36 kg
Alka: 31.05 kg
Answer:
Nayana: 28.76 kgAlka: 31.05 kgAman: 32.63 kgAsif: 32.63 kgStep-by-step explanation: Ascending means increasing, so arrange the weights from the smallest to the biggest.
The weights are all in kilograms (kg) so no conversion is needed. Just arrange the weights by the numbers, 28.76 is the smallest here, and 32.63 is the biggest number, and it is repeated, so in that case the order doesn't matter.
Aman can come before Asif and vice versa since they have the same weights.

Marcel and Floyd are playing games at an arcade. Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games. Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining. Jorge's work is shown below.
Given that,
Marcel has $8.25 and is only playing $0.25 games. Floyd has $9.75 and is only playing $0.75 games.
Jorge wants to find the number of games after which Marcel and Floyd will have the same amount of money remaining.
The attached figure shows the equation that Jorge had :
8.25-0.25x=9.75-0.75x
Subtract 9.75 to both sides
8.25-0.25x-9.75=9.75-0.75x-9.75
-1.5-0.25x=-0.75x
Add 0.25x to the both sides,
-1.5-0.25x+0.25x=-0.75x+0.25x
-1.5=-0.5x
⇒ x = 3
Jorge is incorrect at step 2 where he taken -0.25x to the RHS such that -0.75x+0.25x, he get 0.5x instead of (-0.5x). Hence, From Step 1 to Step 2, Jorge did not add 0.25x correctly to both sides.

An outlier is a number that is much larger or smaller than the general populous of numbers. For example, if there was a dot plot with dots clustered at 2, 3, and 5, but there was one or two dots around 10, then 10 would be considered an outlier.Let's put the numbers in order to see easier which numbers are outliers.

The president of the math club is conducting a survey to see where the twelfth-grade class wants to go on their field trip. Instead of asking the whole class, she surveys only the twelfth-grade members of the math club. She records their choices and plans to present the results to the school principal. What type of sampling did she use? systematic random sampling simple random sampling stratified sampling convenience sampling.
The type of sampling that the teacher used is of the type: Option D: Convenience sampling
What is simple random sampling?If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.
What is stratified sampling?Sampling which is done by taking the main population divided in categories(called strata), then such sampling from stratas (sub-parts of the population) is called stratified sampling.
What is systematic random sampling?In this type of sampling, starting of the sampling is done randomly, but then rest of the samples are collected by an order. Like for example, first point is selected randomly, then all points are selected that they are equidistant from each other in the population.
What is convenience sampling?The word "convenience" summarizes this sampling. It is done in a way that those values from population are sampled which are in convenience with the researcher. Like if some random picking is to be done from beads spread on the ground, then the researcher picking those beads which are closer to him.
So, the math teacher took the sample from a specific part of the whole twelfth class. That's a strata. But sampling was done "only" from 1 strata, which is useless as field trip's data should be taken from other parts of the population too where students might be interested to go for field trip. Thus, its a wrong method of sampling.
That's more of like convenience sampling instead of stratified, where the teacher preferred convenience instead of proper sampling (as the sampling she did is not showing any proper ideology that she might've followed).
Thus, the type of sampling that the teacher used is of the type: Option D: Convenience sampling

Answer: A = 198.6cm²
Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.
r = 10/2= 5cm
Area of circle:
A = πr²
A = 3.142*5²
A = 3.142*25
A = 78.55
A = 78.6cm²
The remaining section of the shape is a rectangle with a length of 12cm.
To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.
The rectangle has a width of 10cm.
Area of rectangle:
A = lw
A = 12*10 = 120cm²
The total area of the shape:
A = 120 + 78.6
A = 198.6cm²
