Answer:

A negative number raised to an odd power is always negative.

Step-by-step explanation:

To complete the statement - A negative number raised to an odd power ______ negative.

Solution :

We know that,

A negative number raised to an odd power is always negative.

1) When a negative number is raised to an even power, the pairs of negatives will cancel out.

For example - (-1)^2=(-1)\times (-1)=1

2) When it is raised to an odd power, after pairs of the negative sign have canceled each other out, there will still be one minus sign left unpaired, which will not cancel out.

For example - (-1)^3=(-1)\times (-1)\times (-1)=1\times (-1)=-1

Therefore, The required blank is 'always'.

neonofarm [45]

Given

Find out the  what was the insurance company's payment .  

To proof

As given

Sally Jones pays $50.00 a month for group health insurance

There is a $300 deductible

Her medical bills for the last year were $2,600.00

Linda's insurance company provided payment of 80% of the bills less the deductible.

Deductible

The  amount of money you will pay in an insurance claim before the insurance company starts paying you.

medical bill reducing the deductible = $2,600 -  $300

                                                             =  $2300

80 % is written in the decimal form

= \frac{80}{100}

= 0.8

than the equation becomes

Linda's insurance company provided payment  = 0.8× 2300

                                                                                = $1840

Therefore the the insurance company's payment be  $1840 .

In a statistics mid-term exam graded out of 100 points, the distribution of the exam scores was bi-modal with a mean of 70 point
Mnenie [13.5K]

Answer:

Step-by-step explanation:

Assuming a normal distribution for the distribution of the points scored by students in the exam, the formula for normal distribution is expressed as

z = (x - u)/s

Where

x = points scored by students

u = mean score

s = standard deviation

From the information given,

u = 70 points

s = 10.

We want to find the probability of students scored between 40 points and 100 points. It is expressed as

P(40 lesser than x lesser than or equal to 100)

For x = 40,

z = (40 - 70)/10 =-3.0

Looking at the normal distribution table, the corresponding z score is 0.0135

For x = 100,

z = (100 - 70)/10 =3.0

Looking at the normal distribution table, the corresponding z score is 0.99865

P(40 lesser than x lesser than or equal to 100) = 0.99865 - 0.0135 = 0.98515

The percentage of students scored between 40 points and 100 points will be 0.986 × 100 = 98.4%
