Answer:
The perimeter would be 8 (units)
Step-by-step explanation:
To find perimeter you just add up all the sides. If your sides are 2 and 2 then the opposite L and W sides should be the same making the total perimeter 8.
Answer:
A = $1,025.00
I = A - P = $25.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Putting time into years for simplicity,
6 months / 12 months/year = 0.5 years.
Solving our equation:
A = 1000(1 + (0.05 × 0.5)) = 1025
A = $1,025.00
The total amount accrued, principal plus interest, from simple interest on a principal of $1,000.00 at a rate of 5% per year for 0.5 years (6 months) is $1,025.00.
Answer: Rejecting the mean weight of each cake as 500 gram when H subscript 0 equals 500
Step-by-step explanation:
Given that :
Null hypothesis : H0 =500
Alternative hypothesis : Ha < 500
Type 1 Error: Type 1 error simply occurs when we reject the Null hypothesis when the Null is true. Alternatively, type 11 error occurs when we fail to reject a false null hypothesis.
Hence, in the scenario above, a type 1 error will occur when we reject the mean weight as 500 even though the Null hypothesis is True.
Answer:
It is letter C! I just learned about this a couple of weeks ago!
Answer:
x=1 and y=7
Step-by-step explanation:
7x−2y=−7;y=7
Rewrite equations:
y=7;7x−2y=−7
Step: Solve y = 7 for y:
y=7
Steps: Substitute 7 for y in 7x−2y=−7:
7x−2y=−7
7x+(−2)(7)=−7
7x−14=−7 (Simplify both sides of the equation)
7x−14+14=−7+14 (Add 14 to both sides)
7x=7
7x/7 = 7/7 (Divide both sides by 7)
x = 1
So the answer is, x=1 and y=7
