Answer:
It's 4 :)I looked it up and the answer I got was 4.Prompt: A car is traveling down a highway at the constant speed, described by the equation “d=65t” , where “d” represents the distance, in miles, that the car travels at this speed in “t” hours.
Question 1:
1. What does 65 tell us in this situation?
a. The car travels 65 miles in 1 hour.
b. The constant of proportionality is 65 miles per hour.
c. The car traveled a total of 65 miles
d. The car is traveling 65 miles per hour.
—————————————————————
Question 2:
2. How many miles does the car travel in 1.5 hours?
The car travels □ miles in 1.5 hours.

Question 3:
3. How long does it take the car to travel 26 miles at this speed?
“Type your response in the down below”
Please Help!
Answer:
1) d
2) 97.5 miles
3)I am unsure on
Step-by-step explanation:
1) d=65t means that it is moving 65 miles per that amount of time (in this case using mph)
2) you take your equation "d=65t" and fill in your time (1.5) 65(1.5)=97.5
3) I don't know but possibly 2.5 minutes? (65/25) but I'm not sure I'm sorry

Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.
Answer:
Explained below.
Step-by-step explanation:
The complete question is:
Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.
1. P(Z < 1.62)
2. P(Z > -1.57)
3. P(-1.41 < Z < 0.63)
Solution:
Use Excel to solve the problems.
(1)
P(Z < 1.62) =NORM.S.DIST(1.62,TRUE)
= 0.9474
(2)
P(Z > -1.57) = P (Z < 1.57)
=NORM.S.DIST(1.57,TRUE)
= 0.9418
(3)
P(-1.41 < Z < 0.63) = P (Z < 0.63) - P (Z < -1.41)
=NORM.S.DIST(0.63,TRUE) - NORM.S.DIST(-1.41,TRUE)
= 0.7357 - 0.0793
= 0.6564

Piper used 1/5 meter of ribbon to create a border around a triangle if each side of the triangle is the same length how much ribbon did Piper use for each side?
Answer:
[tex]\frac{1}{15}[/tex]
Step-by-step explanation:
as said in the question that the triangle has three equal sides. i.e. this is an equilateral triangle. So,
let us consider one side of the triangle to be x . and 3x( x+x+x) should be equal to 1/5
[tex]x+x+x = \frac{1}{5}\\3x=\frac{1}{5}\\x = \frac{1}{5} / 3\\x = \frac{1}{5} * \frac{1}{3}\\x = \frac{1}{15}[/tex]
A password is formed by selecting three letters from the alphabet, followed by one number from 0 to 9. If
repetition is not allowed, how many potential passwords can be created?
A. 156,000
B.175,760
C.140,400
D.85
The number of potential passwords that can be created in this scenario is; C: 140400
How to solve propbability Combinations?There are 26 alphabets in english. Now, if there are no repetitions, then;
Number of ways of selecting first letter = 26
Number of ways of selecting second letter = 25
Number of ways of selecting third letter = 24
Thus;
Number of ways of selecting three letters from the alphabet if there is no repetition is; P(3 letters) = 26 * 25 * 24 = 15600
Number of ways of selecting 1 out of the 9 numbers is = 9
Thus;
Potential passwords that can be created = 15600 * 9 = 140400

−2x−(−5−4x)=−5(2x−7)
Answer:
x = 2.5
Step-by-step explanation:
- 2x - ( - 5 - 4x ) = - 5 ( 2x - 7 )
- 2x + 5 + 4x = - 10x + 35
- 2x + 5 + 4x = - 10x + 35
- 2x + 4x + 10x = 35 - 5
12x = 30
x = [tex]\frac{5}{2}[/tex] = 2.5
Check the answer:
L.H.S. = - 2(2.5) - [ - 5 - 4(2.5) ] = 10
R.H.S. = - 5 [ 2(2.5) - 7 ] = 10
When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey to be 95% confident that the population proportion is estimated to within 0.04
Answer: 601
Step-by-step explanation:
The formula to find the minimum sample size(n) , if the prior population proportion is unknown:
[tex]n=0.25(\dfrac{z^c}{E})^2[/tex], where E = margin of error , [tex]z^c[/tex] = critical z-value for confidence level c.
Given : E = 0.04
Z-value for 95% confidence = 1.96
So, the minimum sample size required = [tex]0.25(\dfrac{1.96}{0.04})^2=0.25(49)^2[/tex]
[tex]= 0.25\times 2401=600.25\approx601[/tex]
Hence, the minimum sample size required = 601
