The answer is: 10 (ten).  

        Ten (10) students in the class have blue eyes.

_________________________________________________________
 
(2/7)* (35) = (2/7) * (35/1) ;  

the "7" cancels to a "1"; and the "35" changes to a "5" ; since "35÷7= 5" ;
___________________________________________________________
   (2/1) * (5*1) = (2*5)/(1*1) = 10/1 = 10 .

     The answer is 10 (ten).  
      Ten (10) students in the class have blue eyes.

35/7 = 5
5 times 2 = 10
That means if 35 students are in the classroom, 10 will have blue eyes.

John has × marbles and max has twice as many.max give gives john 5 of his marbles does max now have
rjkz [21]

Answer: 2x -5

Step-by-step explanation:

Hi, to answer this question we have to write equations with the information given:

  • <em>John has × marbles  </em>

John=x

  • <em>Max has twice (multiplied by 2) as many.max give gives john 5 of his marbles. </em>

We have to multiply by 2 the number of marbles that John has (x), and subtract 5.  

Max = 2x -5

Feel free to ask for more if needed or if you did not understand something.

A gondola (cable car) at a ski area holds 50 people. Its maximum safe load is 10000 pounds. A population of skiers has a distrib
fenix001 [56]

Answer:   0.03855

Step-by-step explanation:

Given :A population of skiers has a distribution of weights with mean 190 pounds and standard deviation 40 pounds.

Its maximum safe load is 10000 pounds.

Let X denotes the weight of 50 people.

As per given ,

Population mean weight of 50 people = \mu=50\times190=9500\text{ pounds}

Standard deviation of 50 people =\sigma=40\sqrt{50}=40(7.07106781187)=282.84

Then , the probability its maximum safe load will be exceeded =

P(X>10000)=P(\dfrac{X-\mu}{\sigma}>\dfrac{10000-9500}{282.84})\\\\=P(z>1.7671-8)\\\\=1-P(z\leq1.7678)\ \ \ \ [\because\ P(Z>z)=P(Z\leq z)]\\\\=1-0.96145\ \ \ [\text{ By p-value of table}]\\\\=0.03855

Thus , the probability its maximum safe load will be exceeded = 0.03855
