Find z such that 4.8% of the standard normal curve lies to the left of z. (Round your answer to two decimal places)
lukranit [14]

Answer:

The correct answer will be "-1.66".

Step-by-step explanation:

Let z₀ be,

P(z

                =0.048

⇒ \Phi (z_0)=0.048

Now,

⇒ \Phi (-1.6646)=0.048

   z_0=-1.6646

       \simeq  -1.66

Thus the above is the right answer.

What are the solutions of the quadratic equation 0 = 4(x - 3)2 - 16?
erastovalidia [21]

Answer:

 x = 5, x = 1

Step-by-step explanation:

The quadratic equation 0 = 4(x - 3)2 - 16.

Using binomial theorem, (a - b)2 = a2 - 2ab + b2 to expand (x - 3)2.

0 = 4(x2 - 6x + 9 ) - 16.

Using distributive property to multiply 4 by x2 - 6x + 9.

0 = 4x2 - 24x + 36 - 16.

Subtract 16 from 36 to get 20.

0 = 4x2 - 24x + 20.

4x2 - 24x + 20 = 0.

Divide both sides by 4.

x2 - 6x + 5 = 0.

To solve the equation, factor and rewrite as x2 + ax + bx + 5

a + b = -6, ab = 1(5) = 5.

a = -5, b = -1.

Rewriting x2 - 6x + 5 as

(x2 - 5x) + (-x + 5)

Factor x in the first and -1 in the second group.

x(x - 5) - (x - 5)

Factor out common term

(x - 5)(x - 1)

By solving the above, we get

x = 5, x = 1

Brent has $26 when he went to the fair. After playing 7 games, he had $15.50 left. Solve 15.50 = 26 - 7p to find the price for e
AveGali [126]

Step 1: Simplify both sides of the equation.

15.5=26−7p

15.5=−7p+26

Step 2: Flip the equation.

−7p+26=15.5

Step 3: Subtract 26 from both sides.

−7p+26=15.5

      -26 -26

−7p=−10.5

Step 4: Divide both sides by -7.

-7p = -10.5

/-7     /-7

Answer:

P = $1.5 (Price for each game)

Hope this helps!
