23) It takes a bus 6 hours to take a trip. The train takes only 4 hours to make the same trip. The train travels
at a rate of speed that is 25 mph more than the speed of the bus. What is the rate of the bus and the rate of
the train? State what x represents, state the equation, and then state the answer.
Rate Time Distance
Bus x 6 бах
Train x-? 2(x+3)
Distance bus travels – Distance train travels
Answers
Answer:
x = 50 mph speed of the bus
y = 75 mph speed of the train
Step-by-step explanation:
Lt´s call "x" speed of bus and "y" speed of train.
According to the problem statement
6*x = 4*y (1)
y = x + 25 (2)
We solve for x and y the two equation system
y = ( 6/4)*x
( 6/4)*x = x + 25
6*x = 4*x + 100
2*x = 100
x = 50 mph
And
y = (6/4)*x
y = 300/4
y = 75 mh

b) Hence explain how you know that x² - 8x + 20 is always positive.
I have worked out the first bit of the question and the answer is:

(x-a)²+a
a= 4

You know that (x-4)^2 is greater than or equal to 0 so by adding 4, the result will always be positive.

In a group of 50 children, 11 cannot swim. What percentage can swim?
Answers
Answer:
78% of the children can swim
Step-by-step explanation:
There are 50 children, 11 of them cannot swim. The fraction of children that cannot swim is 11/50. We have to change that into a percentage.
11/50 x 2 will equal our percentage
11 x 2 = 22
50 x 2 = 100
22/100 or 22%
We have the percentage of the children who cannot swim, now we have to find the percentage of children who can swim.
100% - 22% = 78%

Answers
Answer:
The value is [tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Step-by-step explanation:
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is

Input in standard form the equation of the given line. The line that passes through (-3, 5) and (-2, -6)
Answers
Answer:
The equation in standard form is 11x + y = -28.
Step-by-step explanation:
Let's start with y = mx + b
5 = -3m + b
-6 = -2m + b
Let's take the second less the first.
m = -11
Plug back in the first equation to calculate b.
5 = 33 + b
b = -28
So y = -11x - 28
11x + y = -28

Step-by-step explanation:
The number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.
What is a factorial?The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.
As we can see that the word 'PHILOSOPHY' has 10 letters therefore, the letters of the word can be arranged in the 10! manner, but it contains the letter P, H and O twice therefore, there will be words that will look the same and are counted twice. Thus, the number of ways the word PHILOSOPHY can be arranged are,
[tex]\text{Number of ways} = \dfrac{10!}{2! \times 2! \times 2!} = 453,600[/tex]
Hence, the number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.
