an obtuse triangle has the side as x-3 on the left and then the right says x then the bottom says x+6 can you find the perimeter

user100 [1]

Answer:

P = (x-3) + (x+6) + x

P = 3x+3

Step-by-step explanation:

To find the perimeter of a figure, you just need to add all sides together. First, you need to set up an equation that adds all sides together. Then, you would need to combine like terms (x+x+x=3x); -3+6=3. So you would take 3x and add 3, since 3 is positive.

Hope this helps!

Ground beef is packaged in small trays, intended to hold 1 pound of meat. A random sample of 45 packages in the small tray produ

user100 [1]

Answer:

There is sufficient statistical evidence to suggest that the average weight of the ground beef packaged in small trays is 1 pound

Step-by-step explanation:

Here we have to perform a t-test

Mean = Sample mean = 1.04 lb

μ = Population mean = 1 lb

s = Standard deviation of 0.19

n = Sample size = 45

Null hypothesis H₀ = 1

Alternative hypothesis Hₐ > 1

Therefore from

$t=\frac{\bar{x}-\mu }{\frac{\sigma }{\sqrt{n}}}$ we have

t = 1.412

Critical t at 5% confidence level = 1.68

at 5 % confidence level we obtain the probability P is;

P = 0.0825 > 0.05 Therefore we accept our null hypothesis that the average weight of ground beef per pack is 1 pound.

In this rectangular box, EF = 16, FD = 5, and DB = 30. Find AF.

AVprozaik [17]

Answer:

FA = 25.87

Step-by-step explanation:

Given: BD = 30 , DF = 5 , EF = 16

To find: FA

Rectangular box is a Cuboid.

Figure attached.

AB = FE = 16

So,

In ΔADB

using Pythagoras theorem,

$DB^2=AB^2+AD^2\\30^2=16^2+AD^2\\900=256+AD^2\\AD^2=900-256\\AD^2=644\\AD=\sqrt{644}\\AD=2\sqrt{161}$

Again using Pythagoras theorem in Δ ADF we get

$FA^2=DF^2+AD^2\\FA^2=5^2+(2\sqrt{161})^2\\FA^2=25+644\\FA^2=669\\FA=\sqrt{669}\\FA=25.87$

Therefore, FA = 25.87
