Answer:

100

Step-by-step explanation:

If 30% of all of her muffins are blueberry muffins, that means that 30% of 100% are blueberry. We want to find how many total muffins there are in her basket. Using a ratio:

30 muffins        30%

-----------------  =  --------

x muffins         100%

Cross multiply:

30 (100) = 30 (x)

3000 = 30x

3000/30 = 30x/30

100 = x

x muffins = 100 muffins

So there are a total of 100 muffins in Gary's basket.

Answer:

$4860

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 4500 × 0.04 × 2 = 360

I = $ 360.00

The simple interest accumulated

on a principal of $ 4,500.00

at a rate of 4% per year

for 2 years is $ 360.00.

Answer:

2250

Step-by-step explanation:

you times 4500 with 2 and get 9000. Then, you take the 9000 and divide it by 4 and get 2250.

Answer:

Step-by-step explanation:

3.3w - 9 > -22.2

3.3w > -13.2

w > -4

The number line w + 4 = 0 best represents the solution to the inequality

3.3 w - 9 > -22.2

A linear inequality represents all the possible values of a linear variable.

Given,

            3.3 w - 9 > -22.2

or          3.3 w > -22.2 + 9

             3.3 w >  -13.2

                   w >  -13.2/3.3

                   w >  -4

Hence, the required line is w + 4 = 0 .

Answer:

Math sections = 20

English sections = 16

Philosophy sections = 8

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of Math sections.

y is the number of English sections.

z is the number of Philosophy sections.

Available classrooms limit the total sections of all three courses to 44.

This means that [tex]x + y + z = 44[/tex]

4 less English sections than Math sections.

This means that [tex]y = x - 4[/tex]

In any quarter student demand for the optional Philosophy course is half as many sections as English sections.

This means that [tex]z = \frac{y}{2} = \frac{x - 4}{2}[/tex]

Finding the number of Math sections:

We have both y and z as functions of x. So

[tex]x + y + z = 44[/tex]

[tex]x + x - 4 + \frac{x-4}{2} = 44[/tex]

[tex]2x + \frac{x-4}{2} = 48[/tex]

Multiplying everything by 2

[tex]4x + x - 4 = 96[/tex]

[tex]5x = 100[/tex]

[tex]x = \frac{100}{5}[/tex]

[tex]x = 20[/tex]

Then

[tex]y = x - 4 = 20 - 4 = 16[/tex]

[tex]z = \frac{y}{2} = \frac{16}{2} = 8[/tex]. So

Math sections = 20

English sections = 16

Philosophy sections = 8

Answer:

A)

C ≤ LP   issue warning

C > LP do not issue warning

B )

For ' do not warm ' the condition will be that C is moderate while L is extremely high

Step-by-step explanation:

Assuming Y is an indicator that represents if a warning is issued or not

probability of occurrence of Hurricane = p

where;  C = cost of issuing a warning

             L = cost incurred for not issuing warning

A) Determine if you should issue a warning or not

In this scenario there are about four possible cases

hence the expected cost ( E ) = L ( 1 - Y )p  + Cy

when warning is issued = Y ( 1 )

expected cost ( E ) = C

assuming warning is not issued then Y = 0

hence expected cost ( E ) = LP

Hence the decision rule will be :

C ≤ LP   issue warning

C > LP do not issue warning

B) For ' do not warm ' the condition will be that C is moderate while L is extremely high ( as seen in the question ) because this will make  C/L to be very small. from the condition C > LP  and this simply means that the probability of the Hurricane occurring is very small

Answer:

(c) A false negative (concluding the job candidate is not a drug user when he or she indeed is)

Step-by-step explanation:

First, we need to determine if it is possible for type II error to occur or not.

In analysis, type 2 error occurs when the stated null hypothesis is false.

The given null hypothesis here is  "a job candidate is not a drug user" which indicates false. This means that option (e) cannot be the solution.

Having established that there is a possibility for an occurrence of type II error.

Next, is to determine the error.

Type II error implies false negative; hence, options (a), (b) and (d) cannot be the solution.

(c) is correct.
