Answer:

The first answer: 5bk + 5b + k

Step-by-step explanation:

Now, you might say it would be the 10bk one, but that's not right.

The only you can get two variables together is through multiplication. That's why 10bk would not work.

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
aliya0001 [1]
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.

-x + y = 5
diamong [38]

Answer:

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5...... Equation 1

x - 5y = 2....... Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5...... Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option

Identify the initial value in each formula below, and state whether the formula models exponential growth or
kaheart [24]

Answer:

Intial Value: f(t) = 2 , Exponential Growth

Step-by-step explanation:

To find the initial value, all we have to do is find the value of f(t) at t = 0

In this case the given equation becomes

f(t) = 2(\frac{5}{3})^0

from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)

a^0 = 1

hence the above equation becomes

f(t) = 2(1)\\ f(t) = 2

so the initial value is 2.

To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from

(\frac{5}{3} )^t

is

\frac{5}{3} > 1  or \frac{5}{3} < 1

if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.

Hence since \frac{5}{3} > 1 then this is an exponential growth
