Answer:
416.8 pounds.
Step-by-step explanation:
The mean weight of the 28 bears at a zoo is 413 pounds.
The Total Weight of the 28 bears = Mean weight × number of bears
= 413 pounds × 28 bears
= 11564 pounds
Fuzzy the bear, whose weight is 434 pounds, and Wuzzy the bear, whose weight is 505 pounds, were added to the zoo.
This means the total number of bears
= 30 bears because two additional bears were added
What is the new mean of the weight of the bears at the zoo?
New Mean = 11564 pounds + 505 pounds + 434 pounds/30 bears
= 12503 pounds /30 bears
= 416.76666667 pounds
Approximately to the nearest tenth = 416.8 pounds.
Answer:
C. m represents the slope and b represents the y-intercept.
Step-by-step explanation:
The equation of straight line is usually expressed as:
y = mx + b
Where y is the vertical axis component
x is the horizontal axis component
m is the slope
b is the y-intercept
At the y-intercept, x = 0
Also, the slope is the rise divided by the run.
Answer:
Answer:
WF=34
Step-by-step explanation:
Point I lies between points W and F.
It means point WI + IF = WF
SO WI + IF = WF
=
WF = 15x – 21
WI= 7x-3
IF= 2x+4
WI + IF = WF
7x-3 +2x+4= 15X-21
7x+2x-15x= -21-4+3
-6x = -22
X= -22/6
X= 11/3
So WF = 15x – 21
WI= 7x-3
IF= 2x+4
WI + IF = WF
=
7X-3 +2x+4= 15x-21
7x+2x-15x= -21-4+3
-6x = -22
X= -22/6
X= 11/3
So WF = 15x – 21
WF= 15(11/3) -21
WF= 55-21
WF=34
Answer:
LM=JM
Step-by-step explanation:
- If Jk=Lk Maybe that K was not 90 This means that the triangles are not congruent
- if it was K = 90 maybe Jk ≠ Lk and that means the two triangles are not congruent
- if LM = GM و MK = MK It means that the two triangles are congruent
Answer:
Step-by-step explanation:
