x - y = 16
x^2 + x^2 = 130

----------------
x^2 - y^2 = 256
+(x^2 + y^2 = 130)
2x^2 = 386
x^2 = 193
x = <span>13.892 (3DP)
----
</span>x - y = 16
13.892 - y = 16
-y = 2.108
y = -2.108
The numbers are: 13.892 and -2.108

ale4655 [162]

Hey there! I'm happy to help!

We have 2 thousand dollar bills.

2000

4 hundred dollar bills...

2000+400

and 6 ten dollar bills

2000+400+60=2460

We multiply this amount by 10.

2460(10)=24600

This car costs $24,600

Have a wonderful day! :D

Find the area under the standard normal distribution curve for each.
yawa3891 [41]
From the standard normal tables, obtain
P(z<1.95) = 0.9744
P(z<0.37) = 0.6443
P(z<1.32) = 0.9066
P(z<1.82) = 0.9656
P(z<1.05) = 0.8531
P(z<2.05) = 0.9798
P(z<0.03) = 0.5120
P(z<0.53) = 0.7019

Answers:
    Range of z                                       Area
     --------------   ---------------------------------------
a.     0 - 1.95                                      0.9744
b.     0 - 0.37                                     0.6443
c.  1.32 - 1.82   0.9656 - 0.9066 =   0.0590
d. 1.05 - 2.05  0.9798 - 0.8531   =   0.1267

Six students measure the acceleration (in meters per second per second) of object in free fall. The measured values are shown. T
Sunny_sXe [5.5K]
The measured data is
x=[10.56, 9.52, 9.73, 9.80, 9.78, 10.91].

Calculate the mean.
m = (10.56+9.52+9.73+9.80+9.78+10.91)/6 = 10.05

Calculate the deviations from the mean.
k = x - m
   = [0.51, -0.53, -0.32, -0.25, -0.27, 0.86]

Calculate the absolute deviation from the mean.
d= \frac{1}{6} | (0.51-0.53-0.32-0.25-0.27+0.86) | = |1.184\times10^{-15}| \approx 0
