A. 62. If you add up all of the numbers, you get 310, then take this number and divide it by 5. you divide it by five because there are five numbers given.
Answer: 7/10=35/50
Step-by-step explanation:
1. To get 50, you had to multiply 10 by 5, so do the same to the numerator, 7.
2. 7*5=35.
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
Options :
(A.) y=558-273x (B.) y=264+142x (C.) y = 55.8 +2.79x (D.) y= -26.4-1.42x
Answer:
C.) ŷ = 2.79X + 55.8
Step-by-step explanation:
Given the data:
cost (x): 9 2 3 4 2 5 9 10
Number of products sold: 85 52 55 68 57 86 83 73
Using the online regression calculator to generate a linear regression plot of the given data: the model obtained is given below
ŷ = 2.79X + 55.8
With y being the predicted or dependent variable
Slope or gradient of the line = 2.79
X = the independent variable
55.8 = the intercept.
Answer:
<h3> X=2 and x=4</h3>
Step-by-step explanation:
x+3>0 {or logarithm does'nt have a sense}
-4+3=-1 not >0 so the first two are out
-3+3=0 not >0 so the third also is out
2+3=5>0 and 4+3=7>0, so only the fourth could be the potential answer
