Is this one question correct
1 answer:
Answer: 2/3ft or C
Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh. Divide both sides by h: =b
A = 2/5
h = 6/5
b = ?
Next, we can plug the numbers into this equation: =b
Multiply 2 and 2/5: 4/5 / 6/5
Take the reciprocal of 6/5: 4/5 x 5/6 =
÷

Answer:
y = (5/4)2^x
Step-by-step explanation:
The function value increases by a factor of 40/10 = 4 when x increases by 2. The function can be written as ...
y = (reference value)·(growth factor)^((x -reference)/(change in x for growth factor))
y = 10·4^((x-3)/2) . . . . . . using point (3, 10) as a reference
This can be simplified to ...
y = 10·2^(x -3) = 10/8·2^x
y = (5/4)2^x
Answer:
Step-by-step explanation:
An null hypothesis () is a statement of equality which shows that there is no statistical difference between the groups being tested.
An alternative hypothesis () is a statement of inequality which shows that there is statistical difference between the groups being tested.
Let be the population mean amount of garbage per bin .
Given : A sanitation supervisor is interested in testing to see if the mean amount of garbage per bin is different from 50.
i.e. → Alternative
Thus , the appropriate null and alternative hypotheses :
