To simplify, we need to find a number that can divide both the numerator and denominator equally. Can you find a number that will do this? I can't. So it is already simplified.
Answer:
x=20
m<B=92 degrees
m<C=40 degrees
Step-by-step explanation:
48+6x-28+2x=180
20+8x=180
8x=160
x=20
(6(20)-28)=92
2(20)=40
So, x=20, m<B=92 degrees and m<C=40 degrees
Answer:
c)
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given mean of the normally distribution = 195 pounds
Given standard deviation of the normally distribution
= 20 pounds.
<em>Let 'x' be the random variable of the normally distribution</em>
Let X = 238
<u><em>Step(ii):</em></u>-
<em>The probability of a player weighing more than 238</em>
<em>P( X > 238) = P( Z> 2.15)</em>
= 1 - P( Z < 2.15)
= 1 - ( 0.5 + A(2.15)
= 1 - 0.5 - A(2.15)
= 0.5 - 0.4821 ( from normal table)
= 0.0174
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
The range is wide is the correct answer
Answer:
10.63+0.59=11.22
10.63-9.9=0.73
1x10=10
2x10=20
3x10=30
4x10=40
5/10=0.5
6/10=0.6
7/10=0.7
8/10=0.8
10.63>10.7
you will have to round yourself sorry fam
