Use the T-table below to determine 3 solutions to this equation: y = 2x
Jet001 [13]
The table is attached as a figure

The given equation is ⇒⇒⇒⇒ y = 2x
To solve this equation, we need to pick numbers from the table then this number will be substituted into the equation to find y
we need 3 solutions . so, we need to pick 3 numbers of x
From the table, let us choose x = 0
y = 2x
y = 2 * (0)
y = 0

From the table, let choose second value of x such as x = 1
y = 2 * (1)
y = 2

From the table, let choose third value of x such as x = -1
y = 2 * (-1)
y = -2

So, the picked three solutions are
y = 0  at   x = 0
y = -2  at  x = -1
y = 2 at  x = 1

1.)There is one outlier, indicating very few books were checked out on that day

This is because there is one day where only 2 books were checked out while on all of the other days 35-45 books were checked out.

2.) 0; it represents no correlation between x and y

This is because no matter the age they could answer 17 questions

Hope this helps!

A pancake recipe requires two and three quarters cups of milk to one cup of flour. If three and two thirds cups of milk is used,
MrRissso [65]

Answer:

3/4 cups of flour are needed.

Step-by-step explanation:

(3 2/3)/1=(2 3/4)/x

(11/3)/1=(11/4)/x cross multiply.

11x/3=11/4 cross multiply.

4*11x=3*11

44x=33

x=33/44

x=3/4

SA=4pir^2
78.54km^2=SA
78.54=4pir^2
divide both sides by 4
19.635=pir^2
aprox pi=3.14 so divide both sides by 3.14
6.25318=r^2
sqrt both sides
2.50063=r
round
radius=2.5km

this question is flawed in that it gives the wrong units

answer is the option with 2.5 in it
