Alex wants to arrange chairs in such a way that the number of chairs in a row is equal to the number of columns. He has ordered

PIT_PIT [208]

Answer:

Step-by-step explanation:

In other to have the same number of chayes in both rows and columns ;

If the Number of chairs per row = x ; then number of chairs per column = x

Then the total number of chairs needed = x * x = x²

Hence, if there are 5100 chairs ;

Number of chairs needed more ;

Take the square root of 5100 ;the round to the next whole number :

B.) For number of chairs to be removed ;

Take the square root of 5100 and round down to the whole number.

Hence,

A.) = √5100 = 71.414 = 72

72² - 5100 = 84

B.) 5100 = 71.414 = 71

5100 - 71² =

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 12.3 years, and standard deviation of

Zolol [24]

Answer:

probability of lasting longer = 1.7%

Step-by-step explanation:

We are given:

x' = 14 years

μ = 12.3 years

s = 0.8 years

Thus, let's use the formula for the Z-score value which is;

z = (x' - μ)/s

Thus;

z = (14 - 12.3)/0.8

z = 2.125

From the z-distribution table attached, the p-value is ;

P(x' > 2.125) = 1 - 0.983 = 0.017 = 1.7%

Thus,probability of lasting longer = 1.7%

Which value of a in the exponential function below would cause the function to stretch?

mote1985 [20]

Answer:

a' > a

Step-by-step explanation:

$f(x)=ae^{bx}$

A larger value for a will stretch the exponential in the y direction. A larger value for b will stretch it in the x direction.
