Answer:

Step-by-step explanation:

Answer:

Babies of 33 week weighs relatively less than the babies of 41 week.

Explanation:

Z score is determined by

x-u/sd

A) For 33 Week baby

Given

Mean 2500

SD 800

Z score is

2600-2500/800 =0.125

B) For 41 Week baby

Given

Mean 2800

SD 425

x=2900

Z score is

2900-2800/425 =0.235

The z score depicts that the baby of 33 week or 41 week weighs more than the normal babies of same age group.

Thus, babies of 33 week weighs relatively less than the babies of 41 week.

Find f(−1) given that f(x)=x3+2x2+3x+4. <br>A. 10 <br>B. -2 <br>C. 2 <br>D. -10
Finger [1]

Answer:

The answer is option C

Step-by-step explanation:

f(x) = x³ + 2x² + 3x + 4

To find f(-1) substitute the value of x that's

- 1 into f(x)

That's

<h3>f( - 1) =  ({ - 1})^{3}  + 2 ({ - 1})^{2}  + 3( - 1) + 4 \\  =  - 1 + 2(1)  - 3 + 4 \\  =  - 1 + 2 - 3 + 4 \\  = 1 - 3 + 4</h3>

We have the final answer as

<h3>f( - 1) = 2</h3>

Hope this helps you

A triangle has perimeter 59 cm. The lengths of the sides are 2x – 5 cm, 3x + 2 cm and 2x – 1 cm.
Dennis_Churaev [7]

Answer:2x - 5cm + 3x +2cm + 2x - 1cm=59cm

2x + 3x + 2x + 2cm + 1cm - 5cm=59cm

7x - 2cm=59cm

7x - 2cm + 2cm=59cm + 2cm

7x=61cm

X=8 5/7cm

2x + 5y= 18 4x + 20y= -36 Solve and Explain first to get right gets brainliest
Jet001 [13]

because 4x+20y=-36,so ( 4x+20y)/2=2x+10y=-18

(2x+10y)-(2x+5y)=-18-18

5y=-36

then y=-7.2

because 2x=18-5y

so x=(18-5y)/2=(18-5*(-7.2))/2=27
