The answer is 8:14. this can be simplified to 4:7 (divide by 2).
Set the equations equal to each other and solve for the variable x. then use the answer from x and plug it in to the equations and you should get an answer
3x=63
63÷3=x
21=x
x=21
that is the value of x
73 is the answer to the top equation and the bottom equation in the triangle. Meaning the equations are equal to each other when you have 21 plugged in for the variable x.
make sure to put your label if it asks for it. it means the book or the teacher. go by what the teacher says if it is different from what the book says
Answer:
71.75 in^3
Step-by-step explanation:
If the values are
3 1/2in 5 1/4in 4in
then multiply all three of them
71.75 in^3
Hope I helped!
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
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.
Answer:
∠ABC= 40° ∠CBD=60° ∠EBD=80°
Step-by-step explanation:
Step 1: 2x+3x+4x=180
A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.
Step 2: 9x=180
Combine like terms
Step 3: x=20
Divide/ Isolate the variable
Step 4: 2(20)=40 3(20)=60 4(20)=80
Plug the answer back in
