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

CAMO is a rectangle with diagonals intersecting at W. WA = 4x - 3 , CW = x + 6 , and AO = 22 Find x.
Answer:
x = 3.5
Step-by-step explanation:
diagonals bisect each other so AW = OW
since AO = 22 then AW = 11
11 = 4x - 3
14 = 4x
x = 7/2 or 3 1/2

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.

What percentage of a dollar is the value of each coin combination
1. 4 dimes
2. 1 nickel and 3 pennies
3. 5 quarters and 1 dime
Answer:
1) 40%
2) 8%
3) 160%
Step-by-step explanation:
1) a dime is 10 cents. 10+10+10+10 = 40
.40/1.00 = 0.4 move the decimal to places to the right to turn into a percentage. 40%
2) 1 nickel is 0.05 cents and 3 pennies equal 0.03 cents. 0.05+0.03= 0.08 0.08/1.00=0.08
move the decimal to places to the right to turn into a percentage. = 8%
3) a quarter is 0.25 cents and a dime is 0.10 cents.
6 quarters = 0.25+0.25+0.25+0.25+0.25+0.25= 1.50
1.50 + 0.10= 1.60
1.60/1.00= 1.60 move the decimal to places to the right to turn into a percentage 160%

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 %
∴ percentage of students have blue eyes are 48 %

Finding angle measures between intersecting lines. Note: Angles necessarily drawn to scale. x=__
Answer:
x=25+30=55 since the vertically opposite angle are equal.sorry the no is not clear in question
Answer:
[tex]\boxed{\tt x= 45^{\circ}}[/tex]
Step-by-step explanation:
∠BEG and ∠DEB combine to form ⇒ ∠DEG, which is a vertical angle with ∠x because it's the opposite from ∠x.
(Vertical angles are always congruent, or of equal measure)
So, [tex]\tt \angle BEG +\angle DEB=\angle x[/tex]
[tex]\tt \angle BEG +\angle DEB=\angle x[/tex]
[tex]\tt 25^{\circ}+20=x[/tex]
[tex]\tt 45^{\circ}=x[/tex]

What is the Genotypic and Phenotypic ratio?
Answer:
The phenotypic ratios are the ratios of visible characteristics. The genotypic ratios are the ratios of gene combinations in the offspring, and these are not always distinguishable in the phenotypes.
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)
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)
