Answer:
=17
Step-by-step explanation:
We need the slope and the y-intercept to find the equation of the linear model.
This line goes through (0,28) and (1,26), so the slope is
\frac{26 - 28}{1} = -2
1
26−28
=−2
The equation that best describes this model is
\widehat{y} = -2x + 28
y
=−2x+28
Plug in x = 5.5 in the above equation to get
\widehat{y}
y
=−2x+28
=(−2)(5.5)+28
=−11+28
=17
Based on this equation, the date in April her flowers will bloom if the average temperature in March is
Answer:
-14
Step-by-step explanation:
just like 8+6 = 14
-8-6 = -14
Answer:
Step-by-step explanation:
The GCF (greatest common factor) of 24 and 30 is 6.
30-30/6=25
25 students in the class
24% of 25 is 6
6 girls in the class
Use the quadratic formula .
x^2-2x+11=0
a=1
b=-2
c=11
x=-2+- (-2)^2-4*1*11 divided by 2
x=2+- the square root of -40 divided by 2
There is no real solutions
