I'm having a little bit of trouble figuring out the formula to solve this problem.

goldfiish [28.3K]

Answer:Red price hast he least least cost per gram of apple.

Step-by-step explanation:

1) considering Royal Gala, 75 gram apple cost $0.41

The cost per gram is 0.41/75 = $0.0055

2) considering Honey crisp, 93 gram apple cost $0.82

The cost per gram is 0.82/93 = $0.0088

3) considering Red Prince, 81 gram apple cost $0.36

The cost per gram is 0.36/81 = $0.0044

Since $0.0044 per gram is the lowest of the three, then the type of apple with the least cost per gram is Red prince.

If the level of significance (alpha) is 0.05, it means that the probability of rejecting the null hypothesis, when it is false,

Kaylis [27]

Answer: The probability of rejecting the null hypothesis, when it is true, is 5%.

Step-by-step explanation:

We know that the level of significance ( denoted as $\alpha$ ) is generally the probability of rejecting the null hypothesis when it is true.

Therefore , If the level of significance (\alpha[/tex] ) 0.05, then it means that it is the probability of rejecting the null hypothesis when it is true.

i.e. The probability of rejecting the null hypothesis when it is true= 0.05

In percent : $0.05=5\%$

Hence, the correct option is : The probability of rejecting the null hypothesis when it is true is 5%.

How many solutions are there to the equation below?<br><br> 12x+6=5x

slavikrds [6]

Answer: There is one solution to the given equation.

Step-by-step explanation: We are given to find the number of solutions to the following equation :

$12x+6=5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

Since the given equation is linear in one variable x, so it will have only one solution.

The solution of equation (i) is given by

$12x+6=5x\\\\\Rightarrow 12x-5x=-6\\\\\Rightarrow 7x=-6\\\\\Rightarrow x=-\dfrac{6}{7}.$

Thus, there is one solution to the given equation.
