A red blood cell is 0.000007 m in diameter. There are about 20,000,000,000,000 red blood cells in a 125 lb person. if all the re

d blood cells were lined up in a line end to end how long would the line be?

Multiply 0.000007 (7x10ˆ2) by 20,000,000,000,000 (2x10ˆ13)
<span>The answer is 140,000,000 (1.4x10ˆ8) meters</span>

A car of 1000 kg starts to move from rest and travels a distance of 150 m in 10 second. How much force is needed?

allsm [11]

Initial velocity=u=0m/s
Distance=s=150m
Time=t=10s
Acceleration=a

Using second equation of kinematics

$\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2$

$\\ \sf\longmapsto 150=0(10)+\dfrac{1}{2}a(10)^2$

$\\ \sf\longmapsto 150=\dfrac{1}{2}\times 100a$

$\\ \sf\longmapsto 50a=150$

$\\ \sf\longmapsto a=\dfrac{150}{50}$

$\\ \sf\longmapsto a=3m/s^2$

Mass=m=1000kg
Force=F

Using newtons second law

$\\ \sf\longmapsto F=ma$

$\\ \sf\longmapsto F=1000(3)$

$\\ \sf\longmapsto F=3000N$

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15. If a certain statistician has an of 122 ,

marusya05 [52]

Answer:

B. 93%

Step-by-step explanation:

Find the z-score:

z = (x − μ) / σ

z = (122 − 100) / 15

z = 1.47

Find the probability using a calculator or z-score table.

P(Z < 1.47) = 0.93

What is the value of the expression

dusya [7]

Add up the exponents of i : 0+1+2+3+4 = 10. So we have i^10.

This separates as follows: (i^4)^2 *i^2, which is equal to (1)^2 * (-1) = -1.
