Answer:

3.6 qt. and 2.4 qt respectively

Step-by-step explanation:

Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.

54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution

Cendrick D'Amitrano works Friday and Saturday delivering pizza. He delivers 8 pizzas on Friday. How many pizzas must he deliver
NikAS [45]

Answer:

Number of pizza deliver on Saturday = 14 pizza

Step-by-step explanation:

Given:

Number of delivery day (Friday, Saturday) = 2

Number of pizza deliver on Friday = 8

Average of delivery (Mean) = 11 pizza

Find:

Number of pizza deliver on Saturday

Computation:

Mean = Sum of pizza / Number of delivery day

11 = [8 + Number of pizza deliver on Saturday] / 2

22 = 8 + Number of pizza deliver on Saturday

Number of pizza deliver on Saturday = 22 - 8

Number of pizza deliver on Saturday = 14 pizza

Criminal investigators use biometric matching for fingerprint recognition, facial recognition, and iris recognition. When matchi
expeople1 [14]

Answer:

This is an incomplete question.

Step-by-step explanation:

When we are "testing an hypothesis" there is a null hypothesis (H0) and and alternative hypothesis (Ha). We usually select the null hypothesis as the one we are intending to reject. For example in the present case the null hypothesis is

H0= the mean match score is 80.

And the alternative hypothesis:

Ha= the mean match score is greater than 80.

So, the above means that if H0 is true, the person will not be considered as a suspect of a crime, but is H0 is false and Ha is true, the person will be considered as a suspect.

When we are testing an hypothesis there different kind of erros that we can commit:

- Type I error: is the error that takes place when we reject H0 but it is actually true.

- Type II error: is the error associated to the situation in which we do not reject H0 when it is actually false.

- There are no error when we accept H0 and it is effectively true or when we reject H0 and it is false.

As in the statement there is no "following sentence" to decide if there is a Type I eror, Type II eror or neither, we only can explain as above.
