5. How much force is needed to stop a 1,400 kg truck pulling up to a stop light if
the truck took 4 seconds to stop and was moving at 36 m/s?
Answer:
Step-by-step explanation:
F=ma
F=m(dv/dt)
F=1400(-36/4)
F=-12600N (the negative sign just means the force was slowing the vehicle, the magnitude of the force is just the absolute value.
F=12600N

What is the total number of different 11-letter arrangements that can be formed using
the letters in the word ORTHOGRAPHY?
Answer:
4989600
Step-by-step explanation:
First, find how many letters there are. There is 11 letters.
Next, find which letters are repeated and if so, how many times. The letters O, R, and H are each repeated twice.
Since there are 11 letters, you must do 11 ! (factorial). There are 3 letters that are repeated twice, so you must divide by 2 ! 3 times.
Your equation is:
11!/ 2! * 2! * 2!
It simplifies into 39,916,800/8 which is equal to 4989600

7.1.13 Question Help Use the sample data and confidence level given below to complete parts (a) through (d). A research institute poll asked respondents if they felt vulnerable to identity theft. In the poll, n=992 and x = 570 who said 'yes." Use a 99% confidence level. B Click the icon to view a table of z scores. a) Find the best point estimate of the population proportion p. (Round to three decimal places as needed.)
Answer:
The Point estimate of the Population proportion E = 0.039≅0.04
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 992
and x = 570
The Population proportion
[tex]p = \frac{x}{n} = \frac{570}{992} = 0.5745[/tex]
Step(ii):-
The point estimate of the Population proportion is determined by
[tex]E = 2.576 \frac{\sqrt{0.574(1-0.574)} }{\sqrt{992} }[/tex]
E = 0.039≅0.04
Final answer:-
The point estimate of the Population proportion E = 0.039≅0.04

someone help me please! with questions 1-4 , geometry is not my strong suit
Answer:
for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.
explanation.
for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48
The value of the digit 6 in the number 47,602 is 10 times the value of the digit 6 in which number?
A. 76.201
B. 60.245
C. 53.462
D. 46,290
Answer:
Answer B
Step-by-step explanation:
In 47,602, the six is in the hundreds place.
We can divide 100/10 to get what place value it should be in. This gives us the tens place.
Now, we can see which number has a six in the tens place: Answer B, because sixty is 6 * 10.

g(x) = 4x + 3

Find (g o f)(5)
Answer:
(g o f)(5) = 47
Step-by-step explanation:
We are given a composite function:
g(x) = 4x + 3
f(x) = 3x - 4
We are supposed to find (g o f)(5), which really means g( f(x) ). So, we put the function of f(x) for every x in g(x), like this:
g(x) = 4x + 3
g( f(x) ) = 4(3x - 4) + 3
g( f(x) ) = 12x - 16 + 3
g( f(x) ) = 12x - 13
Now, we also need to evaluate for x = 5, like this:
g( f(5) ) = 12(5) - 13
g( f(5) ) = 47

The probability line shows the probability of 5 chance events (A, B, C, D, and E) occurring. Which THREE statements BEST describe the likelihood of the event occurring?
A) Event A is certain to occur.
B) Event E is certain to occur.
C) Event D is certain to occur.
D) Event B is not likely to occur.
E) Event C has an even chance of either occurring or not occurring.
Answer:
The answer is:
B) Event E is certain to occur.
D) Event B is not likely to occur.
E) Event C has an even chance of either
Step-by-step explanation:
Event E is certain to occur. Event B is not likely to occur and Event C has an even chance of either occurring or not occurring so options (B),(D), and (E) are correct.
What is probability?The probability of an event occurring is defined by probability.
Probability is also called chance because if you flip a coin, the probability of coming head and tail is nothing but the chance that either head will appear.
As per the given probability line.
The probability of event E = 1 so it will be certain to occur.
The probability of event B is very close to zero so it will not likely occur.
The probability of event C is 0.5 so it has an equal chance to occur or not.
Hence "Event E will definitely happen. Event C has an equal chance of happening or not, but Event B is not likely to happen".
