The combined math and verbal scores for females taking the SAT-I test are normally distributed with a mean of 998 and a standard

WARRIOR [948]

Answer: There is 64.8% of females do not satisfy that requirement.

Step-by-step explanation:

Since we have given that

Mean = 998

Standard deviation = 202

We need to find the percentage of females do not satisfy that requirement.

If a college includes a minimum score of 1025 among its requirements,

So, it becomes,

$P(X$

Hence, there is 64.8% of females do not satisfy that requirement.

Toenails grow at an average rate of about 0.05 mm per day, and the average toenail is about 3/4 inch long. About how many months

nirvana33 [79]

0.05 mm * ? days = 0.75 inch

Use proportions

1 mm = 0.0394 inch
0.05 mm = 0.00197 inch

0.75 inch / 0.00197 inch = 380.71

380.71 days / 30 days = 12.7 months

Given (x)=-x²+2x,determine<br> F'(x) using first principle

mote1985 [20]

Hello,
which principle?

f(x)=-x²+2x
==>f'(x)= -2x+2

You mean maybe this

$\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}$

f(x+h)=-(x+h)²+2(x+h)= -(x²+2hx+h²)+2x+2h
f(x)=-x²+2x

$\lim_{h \to 0} \frac{f(x+h)-f(x) } {h}=\lim_{h \to 0}\frac{-2hx-h^2+2h}{h}=\lim_{h \to 0}\frac{-2x-h+2}{1}=-2x+2$
