Pablo grew a plant for school and recorded the growth of the plant
each week. He wrote ordered pairs to organize his data: (1, 5), (2, 8),
(3, 8), (4, 11), (5, 15).
Is this relation a function? Explain.
Answer:
Yes. the relation is a function
Step-by-step explanation:
Here, we want to check if the relation is a function
if a relation is a function, then every x-values (input values) will have one y-value
No two output values (y values) will have a single x value
Looking at the pairs;
It is a function
Although two x values have same y value; 2 and 3 to 8; no two y values have same x value
Hence, the ordered pairs is a function

Step-by-step explanation:
when a car speed is 24 km/hr a journey takes 80 minutes what must the speed be for the same journey to take 60 minutes?
Answer:
32 km/ hr
Step-by-step explanation:
Given that :
Speed of car = 24km/ hr
Time taken =. 80 minutes = 80 / 60 = 1.33333 hours
The distance traveled :
Speed * time
24 km/hr * 1.333333 = 32 km
Speed required to complete 32 km. Journey in 60 minutes = 1 hour
Speed = distance / time
Speed = 32 km / 1 hour
Speed = 32 km/ hr
a) The mean is _____. *
b) The standard deviation is _____. *
c) Approximately _____ % of the data values fall between 223 and 237. *
This is a required question
d) Approximately _____ % of the data values fall between 216 and 244.
e) Approximately _____ % of the data values fall between 209 and 251.
Answer:
If all of the observed values in a sample are close to the sample mean, the standard deviation will be small (i.e., close to zero), and if the observed values vary widely around the sample mean, the standard deviation will be large. If all of the values in the sample are identical, the sample standard deviation will be zero.

Miranna teaches gymnastics lessons at summer
camp. She is paid $12.50 per hour.
If Miranna were offered a raise of 100% of her hourly
rate, how much would she be paid?
An uber charges a flat rate of $6 plus $1.25 per mile. Kayla can spend no more than $27.50. If she wants to tip her driver $4, what is the greatest number of miles she can uber?
Answer:
14
Step-by-step explanation:
to determine the answer
Subtract the amount she wants to tip from the total amount of money she wants to spend
$27.50 - $4 = $23.50
Let m = total miles
the total miles she intends to drive can be determined using this equation
$23.50 = $6 + $1.25m
Collect like terms
$23.50 - $6 = $1.25m
$17.50 = £1.25m
Solve for m
17.50 / 1.25 = 14
On Saturday, a local hamburger shop sold a combined total of 540 hamburgers and cheeseburgers. The number of
cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Saturday?
hamburgers
Answer: 135 hamburgers
540 divided by 4 (ratio of hamburgers to cheeseburgers is 3 to 1) = 135. 135 burgers and (135 times 3) 405 cheeseburgers = 540.
Step-by-step explanation: Hope this helps! :)
Answer: 180 hamburgers were sold on Saturday

Write the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7).
Answer:
y=-3/2x+13
Step-by-step explanation:
Convert to slope-intercept form (y=mx+b):
-3x+2y=10
-3x-10+2y=0
-3x-10=-2y
-3/2x-5=y
y=-3/2x-5
Parallel lines have the same slope, so the slope of the equation will be m₁=m₂ where -3/2=-3/2
Solving for b, the y-intercept, we get:
y=-3/2x+b (Equation so far)
7=-3/2(4)+b [Plugging in (4,7)]
7=-12/2+b
7=-6+b
13=b
Therefore, the equation of the line that is parallel to the line -3x+2y=10 and goes through the point (4,7) is y=-3/2x+13
Write two solution points for the equation y=3x-1 when x us 1 and x is 2

Two numerical patterns are shown below: Pattern A: 4, 8, 12, 16, 20 Pattern B: 8, 16, 24, 32, 40 Select the statement that describes the numerical patterns. The terms in Pattern B are one half the value of the corresponding terms in Pattern A. The terms in Pattern A are one half the value of the corresponding terms in Pattern B. The rule for Pattern B is "multiply by 4." The rule for Pattern A is "multiply by 2."
Answer:
The statement that best describes the numerical patterns is;
The rule for mapping Pattern A to Pattern B is "multiply by 2"
Step-by-step explanation:
The given two numerical patterns are;
Pattern A: 4, 8, 12, 16, 20
Pattern B: 8, 16, 24, 32, 40
Therefore;
The ratio of the corresponding terms of Pattern B and A are;
8/4 = 16/8 = 24/12 = 32/16 = 40/20 = 2
We multiply a value in pattern A by 2 to obtain a corresponding value in Pattern B
Therefore the rule for mapping Pattern A to Pattern B is "multiply by 2".
Answer:
Multiply by 2! Basicly D!

Find the nth term of this quadratic sequence 3,8,15,24,35...
Answer:
n^2 + 2n.
Step-by-step explanation:
n = 1 2 3 4 5
term t = 3 8 15 24 35
Diffs = 5 7 9 11
2 2 2 - so the nth term contains n^2.
n^2 = 1 4 9 16 25
t - n^2 = 2 4 6 8 10
This is an arithmetic sequence with nth term = 2 + (n-1)2 = 2n
So the nth term of the quadratic sequence = n^2 + 2n.

−8(x−6)=32
Answer:
x = 2
Step-by-step explanation:
-8(x-6) = 32 (distribute)
-8x+48 = 32 (subtract 48 from both sides)
-8x = -16 (divide)
x = 2
Answer:
x = 2
Step-by-step explanation:
Divide both sides :
−8(x−6)=32
Divide both sides of the eqaution by -8 :
x - 6 = -4
Move the constant to the right :
x - 6 = -4
Move the constant to the right - hand side and change its sign :
x = -4 + 6
Calculate :
x = -4 + 6
Calculate the sum :
x = 2
Therefore, the answer is x = 2
