Answer:

1 / 12

Step-by-step explanation:

Given the following data:

_______A___ B ___C ___Total

Male__ 10 __ 17 ___6___ 33

Female_ 11__ 15___ 13___ 39

Total___21__ 32__ 19___ 72

Find the probability that the student was male AND got a "C"

Number of males who got C = 6

Total number of student students = 72

P(student was male and got C) = (number of males who got C / total number of students)

= 6 / 72

= 1 / 12

a sandwich shop has 60 stores and 70 percent of the stores are I California. How many stores are in California and Nevada
Aliun [14]

Answer:

The number of stores in California 42

The number of stores in Nevada 18

Step-by-step explanation:

Given as :

The total sandwich shop in California and Nevada = 60

The percentage of shop in California = 70%

So, The percentage of shop in Nevada = 100% - 70% = 30%

Let The number of stores in California = c

And The number of stores in Nevada = n

Now, According to question

The number of stores in California = 70% of the total number of shops

I.e c = \frac{70}{100} ×  total number of shops

Or, c =  \frac{70}{100} × 60

∴   c = \frac{70\times 60}{100}

or, c =   \frac{4200}{100}

or, c = 42

So, The number of stores in California = c =42

Again

The number of stores in Nevada = 30% of the total number of shops

I.e n = \frac{30}{100} ×  total number of shops

Or, n =  \frac{30}{100} × 60

∴   n = \frac{30\times 60}{100}

or, n =   \frac{1800}{100}

or, n = 18

So, The number of stores in Nevada = n = 18

Hence The number of stores in California 42

And The number of stores in Nevada 18   Answer

If 2i is a zero of f(x)=x^4+x^2+a, find the value of a
Sedbober [7]

By the polynomial remainder theorem, because <em>x</em> = 2<em>i</em> is a zero of <em>f(x)</em>, we have no remainder upon dividing <em>f(x)</em> by <em>x</em> - 2<em>i</em>.

Computing the quotient yields

\dfrac{x^4+x^2+a}{x-2i} = x^3+2ix^2-3x-6i+\dfrac{12+a}{x-2i}

Then if the remainder term is 0, follows that <em>a</em> = -12.
