13 people take their driving test on the same day. 9 of them pass. What fraction of people didn’t pass?

Answers

Answer:

30.769230769231% or 4/13

Step-by-step explanation:

The fraction of people didn’t pass is 4/ 13.

We have,

Total number of people taking the test: 13

Number of people who passed: 9

So, the number of people who didn't pass

Number of people who didn't pass = Total number of people - Number of people who passed

Number of people who didn't pass = 13 - 9

Number of people who didn't pass = 4

So, the fraction of people didn’t pass

= 4/ 13.

Which radical expression is equivalent to c^1/2

Answers

Answer: square root of c

Answer:

it would be √c

Step-by-step explanation:

when you have fractional exponets, the denominator becomes the radical that you want to find so in this case since its 2 it would be he nomal √ (remeber that when you have a √ with no numbers. it automatically indciates that there is a two) , the numerator of the fraction is the exponent of the number that is inside the radical so in reality it would be √c^1 but we don't write the exponent 1 so it would be √c

The solutions to the trigonometric equation [tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex] are;

{π/2, 3·π/2}

What is a trigonometric equation?

A trigonometric equation is an equation involving trigonometric functions with the input of the function, represented by a variable. specified equation is presented as follows;

[tex]cos(\frac{\pi}{4} - x) = \frac{\sqrt{2} }{2} \cdot sin(x)[/tex]

The subtraction formula for the trigonometric ratios of cosine can be presented as follows;

cos(A - B) = cos(A)·cos(B) + sin(A)·sin(B)

Therefore;

cos(π/4 - x) = cos(π/4)·cos(x) + sin(π/4)·sin(x)

sin(π/4) = √2/2

Therefore;

cos(π/4 - x) = cos(π/4)·cos(x) + (√2/2)·sin(x)

cos(π/4 - x) = (√2/2)·sin(x)

cos(π/4)·cos(x) + (√2/2)·sin(x) = (√2/2)·sin(x)

cos(π/4)·cos(x) = (√2/2)·sin(x) - (√2/2)·sin(x) = 0

cos(π/4)·cos(x) = 0

cos(x) = 0/cos(π/4) = 0

x = arccos(0) = π/2 + n·π

Where n is an integer, therefore the values of the angle between 0, and 2·π are;

x = π/2 + π × 0 = π/2 and x = π/2 + 1 × π = 3·π/2

x = π/2 and x = 3·π/2

The solutions of [tex]cos(\frac{\pi}{4} - x) =\frac{\sqrt{2} }{2} \cdot sin(x)[/tex] are; {π/2, 3·π/2}

Consider the hospital from problem 4 of the homework that is using a statistical test to decide whether or not to accept future shipments of syringes from a supplier. The two errors the can make are to reject shipments that are actually acceptable and to accept shipments that do not meet the requirements. The hospital has decided that the error of accepting shipments that do not meet the requirements is substantially more important. They would like to ensure that they do not make this error even if that means increasing the chance that they reject acceptable shipments. When selecting their alpha (choosing between 0.01, 0.05 and 0.10) which alpha level provides the highest protection against this type of error?
a) alpha-0.01
b) alpha-o.05
c) alpha-0.10

Answers

Answer:

    The correct option is  a

Step-by-step explanation:

Gnerally assuming that

  The null hypothesis is  that the syringes from a supplier does not meet the requirement

and  

  The  alternative hypothesis is that the syringes from a supplier  meets the requirement

Now in order not to commit type I error which is wrongfully rejecting the null hypothesis then the level of significance need to be  lower than the p-value (this is obtained from the z-table  for any given z-score ) hence the suitable level of significance to achieve the hospitals aim is alpha-0.01
