7 / x+4 = 5/x+1 =


5x+20 = 7x+7 =

20=2x+7

13=2x

x=13/2 = 6.5

6.5+4 = 10.5

6.5+1 =7.5

10.5+7.5 = 18

length of AC = 18

On a number line, the directed line segment from Q to S has endpoints Q at –8 and S at 12. Point R partitions the directed line
MissTica

Answer:

Option B.

Step-by-step explanation:

The given formula is

x=\dfrac{m}{m+n}(x_2-x_1)+x_1

It is given that a line segment has endpoints Q at –8 and S at 12. Point R partitions the directed line segment from Q to S in a 4:1 ratio. It means

m=4

n=1

x_1=-8

x_2=12

Substitute these values in the given formula.

x=\dfrac{4}{4+1}(12-(-8))+(-8)

Therefore, the correct option is B.

Construct the 99% confidence interval estimate of the population proportion p if the sample size is n=900 and the number of succ
oee [108]

Answer:

An 99% confidence interval  of the given proportion

(0.355 , 0.385)

Step-by-step explanation:

Given sample size n= 900

the number of successes in the sample is x=333

The proportion P = \frac{x}{n} = \frac{333}{900} = 0.37

            Q = 1-P =1 - 0.37 = 0.63

<u>Confidence interval</u>:-

99% of confidence interval zα = 2.93

(P - z_{\alpha } \sqrt{\frac{PQ}{n} }  , P + z_{\alpha } \sqrt{\frac{PQ}{n} })

(0.37 - 2.93 \sqrt{\frac{0.37(0.63}{900} }  ,0.37 +2.93 \sqrt{\frac{0.37(0.63}{900} } })

(0.37 - 0.015 , 0.37 + 0.015)

(0.355 , 0.385)

<u>Conclusion</u>:-

<u>An 99% Confidence interval (0.355 , 0.385)</u>

A teacher records the number of students present in her 1st period class each day. This count is a ___________ random variable.
blagie [28]

This count is a discrete random variable (option A).

<h3>What is a discrete random variable?</h3>

A discrete random variable is a variable that contains integers that can only be a limited number of possible values.  A discrete random variable is can contain only a finite set of numbers .

An example of discrete random variable is the number of students in the first period class. It is impossible for the number of students in the class to go on indefinitely.

Discrete random variable has the following properties:

  • It is finite
  • It is numeric
  • It is countable
  • It contains non-negative integers.

A continous random variable is a variable that has an infinite number.
