What is the distance between the points (2, 1) and (14, 6) on a coordinate
plane?
Answer:
13
Step-by-step explanation:
wdadsadawda pls help
Step-by-step explanation:
the equation is
x + 0.25 = 15.75
by subtracting 0.25 from both sides we get
x = 15.75 - 0.25 = 15.50
so, her hourly wage before the raise was $15.50.
she got a raise less than $1/ hour, so her new hourly wage should be less than $15.50 + $1 = $16.50. her new hourly wage of $15.75 is less than $16.50, so the answer is reasonable.
4. Which of the following sets of ordered pairs is a function?
a. {(-3, -2), (-1, 3), (0, -2), (3, 4)}
b. {(0, 1), (3, 2), (5,-3), (0, 2)}
c. {(-7, -7) (-2,5),(-1, 6).(-2,-5)}
d. {(-4,-7), (-9,5), (4, -2), (-9, 0)}
Answer:
a
Step-by-step explanation:
Thing that x = a kid and y = it's biological mother
To be a function you need for each x to have only one y !
a. {(x= -3, y = -2), (x= -1, y= 3), (x=0, y= -2), (x= 3, y= 4)} Is a Function
b. {(x= 0, y= 1), (x= 3, y= 2), (x= 5, y= -3), (x= 0, y= 2)} Not a Function because kid x=0 has two biological mothers y=1 and y=2.
c. {(x= -7, y= -7) (x= -2, y= 5),(x= -1, y= 6).(x= -2, y= -5)}Not a Function because kid x= -2 has two biological mothers y= 5 and y= -5
d. {(x= -4, y= -7), (x= -9, y= 5), (x= 4, y= -2), (x= -9, y= 0)} Not a Function because kid x= -9 has two biological mothers y= 5 , and y= 0

The probability that a certain make of car will need repairs in the first eight months is 0.6. A dealer sells three such cars. What is the probability that at least one of them will require repairs in the first eight months? Round your final answer to four decimal places.
Answer:
There is a 1.8% chance that one of the cars will need a repair in the first month.
Step-by-step explanation:
It’s actually very simple, as we just have to multiply the 0.6% by 3, considering that there are three cars, and we then get the answer; 1.8%.

One-eighth of the parts tooled by a machine are rejects. How many parts were tooled
*437 parts were rejected?
There were 3,496 parts in total that were tooled by the machine.
Assuming the total number of parts tooled is x, that means that 1/8 of x is 437 parts because that was the proportion of the total that was rejected.
To find the total number of parts therefore, use the formula:
Proportion of rejects × x = Number of parts rejected
1/8 × x = 437
1/8x = 437
x = 437 ÷ 1/8
x = 437 x 8
x = 3,496 parts
In conclusion, there was 3,496 parts.

What is the equation of the line that passes through the point (- 3, 1) and has a slope of 2/3?
Step-by-step explanation:
Equation of a line passing through a point (h, k) and slope 'm' will be,
y - k = m(x - h)
If this line passes through a point (-3, 1) and has a slope 2/3 32 .
Therefore, equation of the line will be,
y-1=2/3(x+3)y−1=32(x+3)
y=2/3+2+1y=32x+2+1
y=2/3 x+3y=32x+3
Therefore, equation of the line will be,
y=2/3x+3y=32x+3

Last week Betsy made 80 on her quiz. This week she made 76. What is the percent of decrease in her score?
From the information given, she made an 80 the first week she took the quiz, then the next week she made a 76. Furthermore, we are asked to find the percent decrease.
Decrease means less. And less means subtraction in terms of Mathematics. So, hence, subtract 76 from 80 to find the percent decrease.
80 - 76 = 4
Now, just add the percentage behind the result.
4%
Therefore, the percent decrease in Besty's score is 4%.
