Answer:
y=30x+55
Step-by-step explanation:
$55 is constant because for each trip he will take $55 dollars so that gives you your y-intercept and m=$30 and x is the amount of hours worked. every time x increases he will be making more money

An insurance company checks police records on 582 accidents selected at random and notes that teenagers were at the wheel in 91 of them. Which is a correct 90% confidence interval for the proportion of all auto accidents that involve teenage drivers
Answer:
The 90% confidence interval is [tex]0.1316 < p < 0.1812[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 582
The number of teenagers at the wheel is k = 91
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{91}{582}[/tex]
=> [tex]\^ p = 0.1564[/tex]
From the question we are told the confidence level is 90% , hence the level of significance is
[tex]\alpha = (100 - 90 ) \%[/tex]
=> [tex]\alpha = 0.10[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.645[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]
=> [tex]E = 1.645 * \sqrt{\frac{0.1564 (1- 0.1564)}{582} } [/tex]
=> [tex]E = 0.0248 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\^ p -E < p < \^ p +E[/tex]
=> [tex]0.1564 -0.0248 < p < 0.1564 + 0.0248[/tex]
=> [tex]0.1316 < p < 0.1812[/tex]

In ΔRST, t = 4.1 inches, r = 7.1 inches and ∠S=45°. Find the length of s, to the nearest 10th of an inch.
Answer:
The length of s is 5.1 inches to the nearest tenth of an inch
Step-by-step explanation:
In Δ RST
∵ t is the opposite side to ∠T
∵ r is the opposite side to ∠R
∵ s is the opposite side to ∠S
→ To find s let us use the cosine rule
∴ s² = t² + r² - 2 × t × r × cos∠S
∵ t = 4.1 inches, r = 7.1 inches, and m∠S = 45°
→ Substitute them in the rule above
∴ s² = (4.1)² + (7.1)² - 2 × 4.1 × 7.1 × cos(45°)
∴ s² = 16.81 + 50.41 - 41.1677568
∴ s² = 26.0522432
→ Take √ for both sides
∴ s = 5.10413981
→ Round it to the nearest tenth
∴ s = 5.1 inches
∴ The length of s is 5.1 inches to the nearest tenth of an inch
Answer:
5.1

A number n is no less than -3. what is the inequality
Answer:
n ≥ -3
Step-by-step explanation:
If n can be no less than -3... then we know that n has to be bigger than or equal to -3.
This could also be said as greater than or equal to -3
Conveniently enough... there is a sign for greater than or equal to and it is ≥
10 less than the product

everything is on the image
Answer:
a. 6
b. 12
c. [tex] y = 6x + 12 [/tex]
Step-by-step explanation:
a. Using two pairs of values given, (0, 12) and (1, 18)
Rate/slope = [tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{18 - 12}{1 - 0} = \frac{6}{1} = 6 [/tex]
Unit rate/slope (m) = 6
b. The starting value is the y-intercept (b). It is the value of of y when x = 0.
From the table, when x = 0, y = 12.
Therefore the starting value (b) would be 12.
c. The equation can be written in slope-intercept form, [tex] y = mx + b [/tex], where,
m = slope/rate = 6
b = starting value/intercept = 12.
Plug in the values into the equation
The equation would be:
✅[tex] y = 6x + 12 [/tex]

Answer:
Here GCF is 5z
all terms are divisible by 5z. so greatest common factor is 5z
One form of polynomial is
We factor the polynomial further
Other form of polynomial is

A particle, initially 15m from the origin and travelling at –2 ms^-1, accelerates at a constant rate and ends up –20 m from the origin and travelling at –5 ms^-1. What
is its acceleration?
b) What is the value of 3V125 ?
Answer: 5
Step-by-step explanation: 5 x 5 x 5 = 125 and since your finding the cubed root of 125, there are supposed to be 3 numbers you multiply that are the same. This is why the answer is 5. Plus, Roots are the inverse operation of exponents.

Question: Write a loop that inputs words until the user enters STOP.
Answer:
count = 0
word = input("User Input: ")
while word!="STOP":
count = count+1
print("You entered: "+str(word))
word = input("User Input: ")
print("All done. "+str(count)+" words entered")
Step-by-step explanation:
This line initializes counter variable count to 0
count = 0
This line prompts user for input
word = input("User Input: ")
The following iteration is executed until user enters STOP
while word!="STOP":
This increments counter variable by 1
count = count+1
This prints the word entered by the user
print("You entered: "+str(word))
This line prompts user for another input
word = input("User Input: ")
This prints the number of input by the user
print("All done. "+str(count)+" words entered")
Answer:
c = 0
word = input("Enter a word: ")
while word!="STOP":
c = c+1
print("#" + str(c) + ": You entered "+str(word))
word = input("Please enter the next word: ")
print("All done. "+str(c)+" words entered.")
It said that it was wrong.
