12 students have blue eyes. if there are 25 students in the class, what percent of students have blue eyes
Answer:
3
Step-by-step explanation:
First, you need to turn 12 into 0.12. Then, you multiply that by 25 and boom you get 3.
This is the same every time.
For example, what percent is 28 of 49?
0.28*49=13.72.
Out of 25 students 48% students have blue eyes.
What is percentage?Percentage is the relative value indicating one hundredth part of any quantity.Percentage is denoted by (%).How to find what percent of students have blue eyes?According to the question,
Total number of students in the class = 25Total number of students having blue eyes = 12Now, we can calculate the percentage by the formula, [tex](\frac{number}{total})[/tex] x 100 %
∴ percentage of students have blue eyes [tex](\frac{12}{25})[/tex] x 100 % = 48 %

What is the Genotypic and Phenotypic ratio?Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)
Phenotype is the morphology of a living organism .(the trait you usually observe while looking/tracking the organism)
For an Example:
In the flower of a pea plant there are a pink color(RR) or (Rr) and a white color(rr).
When crossing two hybrid ( with two different letters) pink colors,
P : Rr × Rr
G : R r R r
F1 : RR Rr Rr rr
The phenotype ratio will be (3 pink : 1 white)
The genotype ratio will be [1 (RR) : 2 (Rr) : 1 (rr)]..
Hence Genotype is the genetic make-up of an organism that describes the nature of each trait. (the letters we often write for a certain trait)

Students in a statistics class are conducting a survey to estimate the mean number of units students at their college are enrolled in. The students collect a random sample of 45 students. The mean of the sample is 12.1 units. The sample has a standard deviation of 1.5 units. What is the 95% confidence interval for the average number of units that students in their college are enrolled in
The 95% confidence interval for the average number of units that students in their college are enrolled in is approximately 11.66 to 12.54 units. This means that we are 95% confident that the true population mean lies within this interval.
Here,
To calculate the 95% confidence interval for the average number of units that students in their college are enrolled in, we can use the formula for a confidence interval for a population mean when the population standard deviation is unknown but can be estimated using the sample standard deviation.
The formula for the confidence interval is given by:
Confidence Interval = Sample Mean ± (Critical Value) * (Standard Error)
where:
Sample Mean (x) is the mean of the sample (12.1 units in this case).
Critical Value is the value from the t-distribution corresponding to the desired confidence level and the sample size.
For a 95% confidence level and a sample size of 45, the critical value is approximately 2.013 (you can look this up in a t-table or use a calculator).
Standard Error is the standard deviation of the sample mean, which is calculated as the sample standard deviation divided by the square root of the sample size.
Given the information in the problem:
Sample Mean (x) = 12.1 units
Sample Standard Deviation (s) = 1.5 units
Sample Size (n) = 45
Confidence Level = 95%
Critical Value ≈ 2.013
Now, let's calculate the standard error:
Standard Error = s / √n
Standard Error = 1.5 / √45 ≈ 0.2236
Now, calculate the confidence interval:
Lower bound of the confidence interval:
12.1 - (2.013 * 0.2236) ≈ 11.66
Upper bound of the confidence interval:
12.1 + (2.013 * 0.2236) ≈ 12.54
So, the 95% confidence interval for the average number of units that students in their college are enrolled in is approximately 11.66 to 12.54 units. This means that we are 95% confident that the true population mean lies within this interval.

Answer:
x = 10
Step-by-step explanation:
Angles 12x and 10x + 20 are "vertical angles," meaning that they are identical (same value). Therefore we can write the equation 12x = 10x + 20, which reduces to 2x = 20, or x = 10.
Answer:
x=10
Step-by-step explanation:
Hey There!
Those are a pair of vertical angles
Therefore they are congruent
congruent meaning identical in form
So we would setup and equation and because the angles are congruent the equation would be
12x=10x+20 and solve for x
Step 1 subtract 10x from each side
10x-10x cancels out
12x-10x=2x
now we have
2x=20
Step 2 divide each side by 2
2/2 cancels out
20/2=10
Therefore x=10

A private plane traveled from Seattle to a rugged wilderness, at an average speed of 132 mph. On the return trip, the average speed was 110 mph. If the total traveling time was 6 hours, how far is Seattle from the wilderness?
Answer:
Brainliest PLEASE!
Step-by-step explanation:
a = seattle
b = wilderness
t = time traveling at 132 mph
(4-t) = time traveling at 110 mph
distance traveled at 132 mph = 132(t)
distance traveled at 110 mph = 110(4-t)
but the two distances are equal so:
132t = 110(4-t), solving for t
t = 1.82 hrs
d= 1.82 hrs * 132 m/hr = 240 miles

THE DIRECTIONS ARE ON THE TOP
Answer:
y = 40
Step-by-step explanation:
For #7, we are told that y = 10 when x = 2
We are also told that 'y varies directly as x'. That means there is some constant number, k, so that
Formula --> y = kx
Since y=10 and x= 2, we substitute those numbers into the formula.
We get 10 = k × 2.
So k has to be 5, right?
k = 5
So what is y when x = 8?
Use the formula.
y=kx ---> That gives us y = k × 8. But we know k is 5.
So y = 5 × 8 = 40
y = 40

Answer:
7. y = 5x; y = 40
8. y = 1/3x; y = 8/3
Step-by-step explanation:
In the direct proportion equation y=kx, the value of k can be found as ...
k = y/x . . . . . divide both sides by x to solve for k
__
7. k = 10/2 = 5
The equation is ...
y = 5x
For x=8, the value of y is found using the equation:
y = 5(8) = 40
