You are given the following system.x=2y+42x-3y=11 What method would you use to solve this system?

qwelly [4]

Answer:

substitution

Step-by-step explanation:

We assume the two equations are ...

x = 2y+4
2x -3y = 11

You are given an expression for x. Using that in the second equation will result in an immediate solution for y.

... 2(2y+4) -3y = 11 . . . . . substituting 2y+4 for x

.. y +8 = 11

... y = 3

... x = 2·3 +4 = 10

The solution is (x, y) = (10, 3)

Jean Gray earns a graduated commission of 4% on her first $2000 of sales and 8% on all sales over $2000. Jeans sales for the pas

Ahat [919]

Jean Gray's total earnings over the past week was $3,925

Since Jean earns 4% for the first $2,00 business she does, she earns a base commission of = $2,000*0.04 = $80

Now, we need to find how of additional sales did Jean do over and above the base of $2,000. This is calculated as follows:

Total Sales = 3,925

Base sales =2,000

Add-on sales = 3,925-2,000 = 1,925

For the $1,925 sales, Jeans earns 8% commission, her commission for this will be 1,925*0.08 = $154

So, the total commission = $80 + $154 = $234

Her commission for the week was $234

Use Euler’s method with two steps to estimate y(1) if y(x) is the solution to dy dx = x + y, y(0) = 1. Write your answer in the

tresset_1 [31]

Answer:

1.5

Step-by-step explanation:

The Euler's method is a common approximation method for the solution of differential equations. It can be used to obtain an approximate value of a given function. The Euler's formula is:

$y_{n} = y_{n-1} + hF(_{x_{n-1},y_{n-1}})$

Therefore, n =1 will give:

$y_{1} = y_{0} + hF(x_{0},y_{0})$

h is the step size and it is equivalent to $\frac{x_{1}-x_{2}}{2} = \frac{1-0}{2}=\frac{1}{2}$

$F(x_{0},y_{0}) = x_{0} + y_{0} = 0 + 1 = 1$

$y_{1} = 1 + (0.5)(0+1) = 1 + (0.5)(1) = 1 + 0.5 = 1.5$

Assume the resting heart rates for a sample of individuals are normally distributed with a mean of 75 and a standard deviation o

labwork [276]

Answer:

99.8 %

Step-by-step explanation:

μ = 75 and σ = 5

The information about 68-95-99.7 rule is:

μ ± 0,5σ 68.3 % of all values will be in the interval

[ μ - 0,5σ ; μ + 0,5σ ] [ 72.5 : 77,5 ]

μ ± 1σ 95 % of all values will be in the interval

[ μ - 1σ ; μ + 1σ ] [ 70 : 80 ]

And:

μ ± 1,5σ 99.7 % of all values will be in the interval

[ μ - 1.5σ ; μ + 1.5σ ] [ 67,5 : 82,5 ]

And still 85 is bigger than 82,5 we can conclude that approximately 99.8 % will be smaller than 85 and then "the relative frecuency of rates less than 85 is very high 99.8 %
