In a recent awards ceremony, the age of the winner for best actor was 35 and the age of the winner for best actress was 54. For

Arada [10]

Answer:

The actress has the more extreme age because

Step-by-step explanation:

Given

Male Athletes:

$x = 35$

$\=x = 42.1$

$SD = 6.6$

Female Athletes

$x = 54$

$\=x = 34.3$

$SD = 10.1$

Required

Determine which athlete had more extreme age

To do this, we simply calculate the standard z score using

$z = \frac{x - \=x}{SD}$

For the actor:

$z = \frac{35 - 42.1}{6.6}$

$z = \frac{-7.1}{6.6}$

$z = 1.0758$

For the actress:

$z = \frac{54 - 34.3}{10.1}$

$z = \frac{19.7}{10.1}$

$z = 1.950$

Comparing both z values;

The actress has the more extreme age because

It has a positive z value
Its z value is greater than that of the actor

F(x) = -3(x - 1)2 + 6 in standard form

sladkih [1.3K]

Answer:

Step-by-step explanation:

I think you mean f(x) = -3(x-1)^2+6. The ^ indicates an exponent.

f(x) = -3(x^2-2x+1) +6 = -3x^2+6x+3

There are a total of 120 bicycles and tricycles in a shop. There are 302 wheels in allmany bicycles and how many tricycles are i

Contact [7]

Answer: There are 62 tricycles in the shop.

Step-by-step explanation:

Given: Number of wheels in a bicycle = 2

Number of wheels in a tricycle = 3

Let x = Number of bicycles , y = Number of tricycles.

As per given , we have

x+y =120 (i)

2x+3y=302 (ii)

Multiplying 2 on both sides of (i)

2x+2y=240 (iii)

Subtract (iii) from (ii) , we get

y= 62

Put value of y in (i) , we get

$x+62=120\\\\\Rightarrow\ x=120-62\\\\\Rightarrow\ x= 58$

Hence, there are 58 bicycles and 62 tricycles in the shop.
