The experimental probability that Amir will make a basket is 0.4. The experimental probability that Juju will make a basket is 0
madreJ [45]

Answer:

30 baskets

Step-by-step explanation:

The experimental probability Pa that Amir will make a basket is 0.4;

Pa = 0.4

the experimental probability Pj that juju with make the same basket is 0.6;

Pj = 0.6

Total number of shoot Nt = 150

Number of basket Amir will make is;

Na = Pa × Nt

Na = 0.4 × 150

Na = 60 basket

Number of basket juju will make is;

Nj = Pj × Nt

Nj = 0.6 × 150

Nj = 90 basket

PLS HELP ASAP!! ALGEBRA 9!!<br> 4.29-x+36=102-2.52x+2
Andrei [34K]

Answer:

  x = 29

Step-by-step explanation:

If the equation is :

4.2(9-x)+36=102-2.5(2x+2)

→distribute 4.2 and -2.5 in parenthesis

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

→  have terms with x = terms without x

Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign.

4.2(9 - x) + 36 = 102 -2.5(2x + 2)

37.8 - 4.2x +36 = 102 -5x -5

 - 4.2x  +5 x  = - 37.8 - 36 + 102 - 5

→ Combine like terms

             0.8x  = 23.2

→ Divide both sides by 0.8

                    x = 29

Solve for x. <br>0.71= 1/2(9.8) x^2. ​
Fudgin [204]

Answer: 0.38065

in simpler terms x=±  0.145  =±0.38065

Step-by-step explanation: -490x2+71 = 0  

Subtract  71  from both sides of the equation :  

                     -490x2 = -71

Multiply both sides of the equation by (-1) :  490x2 = 71

Divide both sides of the equation by 490:

                    x2 = 71/490 = 0.145

 

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:  

                     x  =  ± √ 71/490  

The equation has two real solutions  

These solutions are  x = ±√ 0.145 = ± 0.38065
