Answer:
500
Step-by-step explanation:
![\mathbb P(X>250)=1-\mathbb P(X\le250)](https://tex.z-dn.net/?f=%5Cmathbb%20P%28X%3E250%29%3D1-%5Cmathbb%20P%28X%5Cle250%29)
![\mathbb P(X\le250)=\mathbb P\left(\dfrac{X-200}{20}\le\dfrac{250-200}{20}\right)=\mathbb P(Z\le2.5)\approx0.9938](https://tex.z-dn.net/?f=%5Cmathbb%20P%28X%5Cle250%29%3D%5Cmathbb%20P%5Cleft%28%5Cdfrac%7BX-200%7D%7B20%7D%5Cle%5Cdfrac%7B250-200%7D%7B20%7D%5Cright%29%3D%5Cmathbb%20P%28Z%5Cle2.5%29%5Capprox0.9938)
which means
![\mathbb P(X>250)\approx1-0.9938=0.0062](https://tex.z-dn.net/?f=%5Cmathbb%20P%28X%3E250%29%5Capprox1-0.9938%3D0.0062)
so approximately 0.62% of pandas weight over 250 pounds.
The angles ∠ABC and ∠CBE together should equal 180º.
∠ABC is 155º.
180 - 155 = 25
So, ∠CBE = 25º.
Hope this helps!
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute (7, 8) into the partial equation
8 = - 21 + c ⇒ c = 8 + 21 = 29
y = - 3x + 29 → A
