Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probabili
3241004551 [841]

Answer:

P(p>0.43) = 0.0436

Step-by-step explanation:

Given

p = 40\% -- proportion of baseball players

n = 781 --- selected sample

Required

Determine P(p>43%)

First, calculate the z score using:

Z = \frac{\^{p}-p}{\sqrt{\frac{p(1-p)}{n}}}

This gives:

Z = \frac{48\%-40\%}{\sqrt{\frac{40\% *(1 - 40\%)}{781}}}

Convert % to decimal

Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *(1 - 0.40)}{781}}}

Z = \frac{0.43-0.40}{\sqrt{\frac{0.40 *0.60}{781}}}

Z = \frac{0.43-0.40}{\sqrt{\frac{0.24}{781}}}

Z = \frac{0.03}{\sqrt{0.00030729833}}

Z = \frac{0.03}{0.01752992669}

Z = 1.71

So:

P(p>0.43) = P(Z>1.71)

P(p>0.43) = 1 - P(Z

P(p>0.43) = 1 - 0.9564

P(p>0.43) = 0.0436

5. A family spends T 600.00 a day for food which is 40% of the
BabaBlast [244]

Answer:

<h3>15%</h3>

Step-by-step explanation:

<h3>First , We will solve their daily Income </h3>

• Income = spends / rate

• Income = 600 / 40%

• Income = 600 / 0 .40%

• Income = 1500

Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .

• Rate = spent / Income

• Rate = 225 / 1500

• Rate = 0.15

• Rate = 15%

Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%

Factorise the given question: 3p^-7p-6​
My name is Ann [436]

Answer:

(p−3)⋅(3p+2)

Step-by-step explanation:

STEP 1 :

Equation at the end of step 1

(3p2 -  7p) -  6

STEP 2 :

Trying to factor by splitting the middle term

2.1     Factoring  3p2-7p-6  

The first term is,  3p2  its coefficient is  3 .

The middle term is,  -7p  its coefficient is  -7 .

The last term, "the constant", is  -6  

Step-1 : Multiply the coefficient of the first term by the constant   3 • -6 = -18  

Step-2 : Find two factors of  -18  whose sum equals the coefficient of the middle term, which is   -7 .

-18 + 1  = -17  

-9 +2 = -7 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -9  and  2  

                    3p2 - 9p + 2p - 6

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3p • (p-3)

             Add up the last 2 terms, pulling out common factors :

                   2 • (p-3)

Step-5 : Add up the four terms of step 4 :

                   (3p+2)  •  (p-3)

            Which is the desired factorization

Final result :

 (p - 3) • (3p + 2)
