There are 1420 students enrolled at Senn. If 60% of these students walk to school, how many students are walking to school?
I need an explanation also :)
Answer:
852 students walking to school
Step-by-step explanation:
Lets start with a simple example so you can get it
if 60% of 100 students walk to school that means
60 students walk to school... right??
so lets simplify it more that means you have multiplied 100 (students) by 60%
or [tex]\frac{60}{100}[/tex] (note: you can say that 60% is equal to [tex]\frac{60}{100}[/tex] )
so the problem told 60% of 1420 students walk to school that means we should
do this: [tex]1420*\frac{60}{100} = 852[/tex]
Answer:
852 walk to school
Step-by-step explanation:
i got this because i divided the 1420 into 10 which became a 142, multiply by 6 and you get 852
also you could
it is really simple also, all you have to do is multiply the number of student, S times the precent of students who walk, so s times w, which is 60 precent turend into .6 precent so 1420 x .6
can you please show me how you got the answer (50 points)
Answer:
[tex]4x^{6}2y^{-2}[/tex]
Step-by-step explanation:
We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)
But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.
We will start with the x in the numerator.
3*4 = 12
Now for the y in the numerator.
4*4 = 16
Our new numerator is [tex]4(2x^{12}y^{16})[/tex]
We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.
We will start with x's coefficient.
2*4 = 8
Now for y's coefficient.
1**4 = 4
*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.
Our final simplified numerator is [tex]8x^{12}4y^{16}[/tex].
Repeat with the denominator.
Try it yourself!
Make sure that when you finish, you finish the fraction.
After completing the denominator, your completed fraction should be:
[tex]\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}[/tex]
Now we can use the SEi-F to complete the problem.
Start with x.
8x - 4x = 4x
12 - 6 = 6
The first term is [tex]4x^{6}[/tex].
Now for y.
4y - 2y = 2y
16 - 18 = -2
The second term is [tex]2y^{-2}[/tex]
The complete, simplified equation is [tex]4x^{6}2y^{-2}[/tex].
I could be wrong on the answer, but the work should be correct.
Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

PLEASE HELP ME WITH THE LITTLE QUESTION
Answer:
y = -x +2
Step-by-step explanation:
First let's find the slope.
(-1,3) and (4,-2)
3 - -2/ -1 - 4 = 5/-5 = -1
Slope = -1
Now let's use slope intercept form:
y1-y2=m(x1-x2)
Let's plug in our slope for m.
y1-y2= -1 (x1-x2)
And now let's substitute y2 and x2 for one of our points, I'll use (4,-2)
y1+2 = -1(x1- 4)
y= -x + 4 -2
y = -x +2

By visual inspection, determine the best-fitting regression model for the data plot below. A. exponential B. linear decreasing C. linear increasing D. no pattern
The best-fitting regression model for the data plot given is linear decreasing. Therefore, option B is the correct answer.
What is linear regression?Linear regression is a linear approach for modelling the relationship between a scalar response and one or more explanatory variables. The case of one explanatory variable is called simple linear regression; for more than one, the process is called multiple linear regression.
In the given graph, the data plot shows the decreasing order.
Therefore, option B is the correct answer.

The rent for a one-bedroom apartment in Southern California follows the normal distribution with a mean of $2,350 per month and a standard deviation of $260 per month. The distribution of the monthly costs does not follow the normal distribution. In fact, it is positively skewed. What is the probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month
Answer:
0.9974 = 99.74% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month.
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
The rent for a one-bedroom apartment in Southern California follows the normal distribution with a mean of $2,350 per month and a standard deviation of $260 per month.
This means that [tex]\mu = 2350, \sigma = 260[/tex]
Sample of 65 one-bedroom apartments
65>30, which means that the sampling distribution of the sample means will be approximately normal. Also, [tex]n = 65, s = \frac{260}{\sqrt{65}} = 32.249[/tex]
What is the probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month?
This is 1 subtracted by the pvalue of Z when X = 2260.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{2260 - 2350}{32.249}[/tex]
[tex]Z = -2.79[/tex]
[tex]Z = -2.79[/tex] has a pvalue of 0.0026
1 - 0.0026 = 0.9974
0.9974 = 99.74% probability of selecting a sample of 65 one-bedroom apartments and finding the mean to be at least $2,260 per month.

Suppose a civic engineer wants to conduct a survey to find out if residents of a city would be in favor of widening one of the city's roadways for increased traffic flow
a. Would a sample consisting of residents who utilize that roadway to travel to work each morning be representative? Explain.
b. Would a sample consisting of residents who live along that roadway be representative? Explain.
c. Would a random sample of homeowners in the city be representative? Explain.
9514 1404 393
Answer:
a, b, c --- all not representative
Step-by-step explanation:
The question posed by the engineer is "are residents of the city in favor of ...".
The only representative sample is one from a pool that includes all residents of the city—not just those who (a) use the road, (b) live along the road, or (c) own homes.
__
Additional comment
The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.

What value of x would make the following relation a function?
Answer: the answer is
C.) -2
Step-by-step explanation:
I got this answer by simply looking at the pattern. It goes -2,-3,2,3, and then starts over, So the answer would have to be -2. I hope this helped and good luck:))
The value of x that would make the relation a function is x = 3.
Option D is the correct answer.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
{ (-2, -3), (-3, -2), (2, 3), (3, 2), (x, 2) }
A function can not be one-to-many.
A function can be many-to-one and one-to-one
Now,
If x = 2, -3, -2 we get one-to-many.
But if x = 3 we get one-to-one.
Thus,
x = 3.

Adter dinner, 3/4 of a pie ramains. If tasha eats 1/6 of the remaining pie, how much of the total pie does tasha eat?
Answer:
Adter ate [tex]\frac{1}{4}[/tex] of the remaining pie.
Step-by-step explanation:
equation:
⇒ [tex]\frac{3}{4} - \frac{1}{6}[/tex]
when subtracting fractions, make sure both denominators are the same, to do this, multiply the first fraction by 3 and the second fraction by 2
⇒ [tex]\frac{3}{4} x 3 - \frac{1}{6} x 2[/tex]
⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]
solve:
⇒ [tex]\frac{9}{12} - \frac{6}{12}[/tex]
⇒ [tex]\frac{3}{12}[/tex]
simplify:
⇒ [tex]\frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]
