Answer:
I think it's False .
Step-by-step explanation:
Hope it works out!!
<span> y = 2/7 x - 1/7
slope = 2/7
</span><span>perpendicular lines, slope is opposite and reciprocal
</span>so slope of new line = -7/2
<span>passes through the point (9,-32)
</span><span>slope-intercept form: y = mx + b
so
b = y - mx
b = -32 - (-7/2)(9)
b = -32 + 63/2
b = -1/2
equation in </span>slope-intercept form:
y = -7/2 x - 1/2
Answer:
Option B.
Step-by-step explanation:
It is given that all of the students of Music High School are in the band, the orchestra, or both.
Students only one group = 80%
Students in both groups = 100%-80% = 20%
Students in band only = 50%
Students in band = Students in band only + Students in both groups
= 50% + 20% = 70%
Students in orchestra only = 100% - 70% = 30%
There are 119 students in the band.
Let total number of student be x.




Total number of students is 170.
We know that 30% of all students are in orchestra only.

Therefore, the correct option is B.
Well it’s to hard
I don’t know it
Answer:
(a) The probability of more than one death in a corps in a year is 0.1252.
(b) The probability of no deaths in a corps over 7 years is 0.0130.
Step-by-step explanation:
Let <em>X</em> = number of soldiers killed by horse kicks in 1 year.
The random variable
.
The probability function of a Poisson distribution is:

(a)
Compute the probability of more than one death in a corps in a year as follows:
P (X > 1) = 1 - P (X ≤ 1)
= 1 - P (X = 0) - P (X = 1)

Thus, the probability of more than one death in a corps in a year is 0.1252.
(b)
The average deaths over 7 year period is: 
Compute the probability of no deaths in a corps over 7 years as follows:

Thus, the probability of no deaths in a corps over 7 years is 0.0130.
