Find the missing term and the missing coefficient 6a −( )5a =( ) a2 − 35a

Answers

Answer 1
Answer: Solving for the missing term and the missing coefficient (6a − )5a = ( ) a^2 − 35a
 Let the missing term be X
 Let the missing coefficient be Y
 Therefore, (6a – X)5a = Y(a^2) – 35a
 6a x 5a – X.5a = Y.a^2 – 35a
 30a^2 – X.5a = Y.a^2 – 35a
  Equating co-efficients,
30a^2 = Y.a^2; X.5a = 35a
 30 = Y; 5X = 35
Y = 30; X = 7
   Therefore, (6a-7)5a = 30 a^2 – 35a

a car is designed to last an average of 12 years with a standard deviation of 0.8 years. what is the probability that a car will last less than 10 years?

Answers

The probability that the car will last less than 10 years would be .0062. With the given data (M = 12, SD = .8), i computed the z-score and looked it up on the z table. The answer yields .0062 or 0.62%. Thus, the probability is very little.

Answer: 0.621%

Step-by-step explanation:

The Johnsons own a home whose market value is $93,000. Their municipality taxes at 80% and the rate is 65 mills or $65 per thousand. What will the Johnsons pay in taxes?

Answers

Answer: He paid $ 4836 in taxes.

Step-by-step explanation:

Here, the total value of the house = $ 93,000

And, the amount on which municipal taxes imposed = 80% of the value of house

= 80% of 93000

=  0.8 × 93000

= $ 74,400

Now, the tax rate is $65 per thousand,

⇒ \text{The amount of tax for 1000 dollars }= \$ 65,

⇒ \text{The amount of tax for 1 dollar}=(65)/(1000)

⇒  \text{The amount of tax for 74400 dollars}=(74400* 65)/(1000)

=(4836000)/(1000)

=\$ 4836

Thus, he paid $ 4836 in taxes.

Answer:

6760

Step-by-step explanation:

80% x 93000 = 74400

74.4 x 65 = 6760

What survival rate in the 10th year would make the average rate of loss over the 10-year period equal to 38.0%?

Answers

Answer: 63%

Step-by-step explanation:

First find the rate of loss that would cause the average rate of loss over the 10-year period equal to 38.0%.

Assume that rate is x.

38 = (36.2 + 29.0 + 46.2 + 37.5 + 40.9 + 40.0 + 32.6 + 40.5 + 40.1 + x) / 10

38 = (343 + x ) / 10

380 = 343 + x

x = 380 - 343

x = 37%

The survival rate is the opposite of the rate of loss which means that the survival rate is;

= 1 - rate of loss

= 1 - 37%

= 63%
