SOLVING:
X + (X + 1) + (X + 2) + (X + 3) + (X + 4) = - 75
X + X + 1 + X + 2 + X + 3 + X + 4 = - 75
5X + 10 = - 75
5X = - 75 - 10
5X = - 85
X =
\frac{ \textbf{-85}}{ \textbf{5}}
X = - 17  ===> The first number.

- 17 + 1 = - 16  ===> The second number.
- 17 + 2 = - 15  ===> The third number.
- 17 + 3 = - 14  ===> The fourth number.
- 17 + 4 = - 13  ===> The fifth number.

TESTING:

-17-16-15-14-13=-75\\ \\\boxed{-75}=\boxed{-75}\quad\checkmark\ Correct.
GOOD LUCK...!!

Hello! I can help you with this! Do -75/5 to get -15. -15 will be your middle number. So for consecutive integers, -13 + -14 + -15 + -16 + -17 = 75. Those are five consecutive integers that have a sum of 75. The lowest of 5 integers is -17, because it’s the smallest of them all and the furthest to the left of the number line. A line further to the left of the number line means it’s smaller. Therefore, the rest of the five integers is -17.

Answer: y=-9.9

x has decreased by 3.3

x=9.9-3.3

=6.6

so you do the same to y

y=-6.6-3.3

=-9.9

The relationship between a sample and a statistic is the same as the relationship between:_______.
shusha [124]

Answer:

Option A) a population and a parameter.

Step-by-step explanation:

Sample and Population:

  • Population is the collection of all the possible observations of an event.
  • A sample is a part of population and always smaller than the population.
  • A sample is a subset of the population.

Statistic and parameter:

  • Any numerical value that may define a property of the sample is known as the statistic.
  • Any numerical value that may describe a population is know as parameter.

The relationship between a sample and a statistic is the same as the relationship between

Option A) a population and a parameter.

Suppose x is a random variable best described by a uniform probability distribution with c=20 and d=40.
olga_2 [115]

Answer:

P(20≤x≤35) = 0.75 .

Step-by-step explanation:

We know that the probability distribution function of Uniform Distribution is represented as :

     If x follows Uniform(c,d) then,

          f(x) = \frac{1}{d-c} where c < x < d

<em>To fond the given probability it is better to first calculate the Cumulative Distribution Function(CDF) of Uniform Distribution.</em>

The CDF of Uniform Distribution is P(X<=x) = \frac{x-c}{d-c} where d > c .

Therefore, P(20<=x<=35) = P(x<=35) - P(x<20)

  P(x<=35) =  \frac{x-20}{40-20}  because we are given c = 20 and d = 40.

                 = \frac{35-20}{40-20} = 0.75

 P(x<20) =  \frac{x-20}{40-20}  = \frac{20-20}{40-20} = 0

Hence, P(20<=x<=35) = 0.75 - 0 = 0.75.

Show whether or not the pair of triangles is similar. Complete the justification of your answer, and select a similarity stateme
geniusboy [140]
BC/DC = 8/3.2 = 2.5
AB/BD = 12.5/5 = 2.5
AC/BC = 20/8 = 2.5

Since the results are all 2.5, this means that the triangles are similar triangles. 

The justification you would use is the SSS similarity theorem. 

SSS = side side side
