A = ½ (b × h) is the formula! Let me know if I can help further:)
Answer:
X = 10
Step-by-step explanation:
The equation to use would be; 2x + 30 = 5x; because the baker is looking for enough to cover the costs, no more no less.
Then all you have to do is solve for the equation.
2x + 30 = 5x
Subtract 2x from each side
30 = 3x
Divide by 3
10 = x
The baker needs to sell 10 muffins in a day to make enough to cover the revenue.
Answer:
H0 : p = 0.75
H1 : p ≠ 0.75
Step-by-step explanation:
The population proportion, P0 = 0.75 ;
Claim is that proportion of customers who use online coupons when making purchases is actually different than P0 = 0.75 (this is the calm) and the difference could be either more or less
Hence, the null hypothesis H0 : says P0 is 0.75 ;
H0 : p = 0.75
The alternative hypothesis, negating the null hypothesis argues that the proportion is not 0.75 (the difference could be either to the right or left).
H1 : p ≠ 0.75
Yes, it is a right triangle.
