A train company moves people between Boston and Providence every day. They travel from city to city 7 times each day. The distance between the two cities is 48 miles. In February, there are 28 days. The company's budget allows for 15,000 total miles in February. Do you think the budget is reasonable? Explain.
Answers
Answer: the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget
Step-by-step explanation:
Given data:
Distance between two cities = 48 miles
Number of days available in February = 28
February budget = 15000 miles
Solution:
If the distance between two cities = 48 miles, and 7 trips are made daily
= 48miles * 7
= 336 miles is travelled each day.
For February
= 28days * 336
= 9408 miles.
Budget – travel distance covered ( February)
= 15,000 - 9408
= 5592 miles.
The budget is reasonable because, by following the travel pattern or history the total travelled miles would be 9408 miles for February which is below the budget allowed by the company for the month.
So the budget is reasonable since the calculated distance travelled hasn’t exceeded the budget.

Find the mean, variance and standard deviation of the binomial experiment. In a recent survey, 70% of the community favored building a police substation in their neighborhood. If 30 citizens are chosen, what is the mean number favoring the substation? What would be the variance and standard deviation of their responses?
Answers
Answer: Mean = 21 , Variance = 6.3 , standard deviation =2.51
Step-by-step explanation:
Formula for the mean, variance and standard deviation of the binomial experiment :
[tex]Mean = np\\\\ Variance = np(1-p)\\\\ Standard\ deviation = \sqrt{variance}[/tex]
, where n= sample size , p= population proportion.
As per given, p= 70%=0.7 , n=30
[tex]Mean = 0.7\times30=21\\\\Variance =(30)(0.7)(1-0.7)=(21)(0.30)=6.3\\\\ Standard\ deviation = \sqrt{6.3}\approx2.51[/tex]
Hence, Mean = 21 , Variance = 6.3 , standard deviation =2.51

Answers
Answer:
An equation in standard form modeling this situation is:
75x + 50x = 425
Step-by-step explanation:
Let
x represent the number of pairs of socks you buy
y represent the number of pairs of gloves you buy
Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php.
The equation is given as:
75php × x + 50php × y = 425php
= 75x + 50y = 425
Therefore,
the equation in standard form modeling this situation is:
75x + 50x = 425

Write the slope-intercept form of the equation for the line that passes through the point (-1,3) and has a slope of 5/3
Answers
Answer:
[tex]y=\frac{5}{3}x+4\frac{2}{3}[/tex]
Step-by-step explanation:
slope-intercept form: y = mx + b
Given:
Slope(m) = [tex]\frac{5}{3}[/tex]
Point = (-1, 3)
To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:
[tex]3=\frac{5}{3}(-1)+b[/tex]
[tex]3=-\frac{5}{3}+b[/tex]
[tex]4\frac{2}{3}=b[/tex]
Now that we know the values of b and m, we can write the equation:
[tex]y = \frac{5}{3}x+4\frac{2}{3}[/tex]

[tex] m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\
m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\
m\angle y +m\angle z= m\angle w +m\angle x\\[/tex]
Hence proved
2. In [tex] \triangle PQS, \: \angle QSR [/tex] is exterior angle.
Therefore, by remote interior angle theorem, we have:

m\angle PQS= 2x-x\\\\
m\angle PQS = x.... (1)\\\\
m\angle QPS = x.... (given).... (2)\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle PQS = m\angle QPS\\\\
\therefore \angle PQS \cong \angle QPS\\\\

Answer:
B. 75.8 ft²
Step-by-step explanation:
The height of each triangle can be found using the Pythagorean theorem. The given edge length (7 ft) is the hypotenuse of the triangle, and the base edge length is twice one leg of the triangle.
The height of the triangle on the 2 ft faces is ...
√(7² -1²) = √48 = 4√3
The height of the triangle on the 8 ft faces is ...
√(7² -4²) = √33
The areas of the triangular faces are the product of the height and half the base length:
A = 1/2bh
2 ft edge triangle area = (1/2)(2 ft)(4√3 ft) = 4√3 ft²
8 ft edge triangle area = (1/2)(8 ft)(√33 ft) = 4√33 ft²
__
The area of the rectangular base is ...
A = LW
A = (8 ft)(2 ft) = 16 ft²
__
The total surface area of the pyramid is the sum of the areas of the triangular faces and the area of the rectangular base.
2(4√3 +4√33) +16 = 8(2+√3+√33) ≈ 75.813
The total surface area is about 75.8 ft².
