$3x+2y=-8<br>1 x - y = -1​
Mrac [35]

Answer:

Step-by-step explanation:

in order to solve this system of equation we would say that let

3x+2y=-8........................................................ equation 1

1 x - y = -1​ ........................................................ equation 2

from equation 2

1 x - y = -1​ ........................................................ equation 2

x = -1 + y....................................... equation 3

substitute for equation 3 in equation 1

3x+2y=-8........................................................ equation 1

3( -1 + y) + 2y = 8

-3 + 3y +2y = 8

collect the like terms

-3 + 5y = 8

5y = 8 + 3

5y = 11

divide both sides by the coefficient of y

5y/5 = 11/5

y = 2.2

put the value y = 2.2 into equation 3

x = -1 + y....................................... equation 3

x = -1 + 2.2

x = 1.2

therefore th value of x is 1.2 and y is 2.2

A researcher is planning to construct a one-sample z ‑confidence interval for a population mean ????. Select the statements that
labwork [276]

Answer:

Step-by-step explanation:

Given that a researcher is planning to construct a one-sample z ‑confidence interval for a population mean

The confidence interval would be calculated as

Sample mean +/-Z_(crit)*std dev/\sqrt{n}

Here margin of error = Z critical * std error determines the size of the confidence interval

Margin of error dependds on i) Z critical value ii) std deviation

iii) Inversely to square root of sample size.

Hence margin of error would be small if

.B) The researcher increases the sample size

C) The researcher lowers the confidence level

E) The population standard deviation turns out to be lower than expected.

I need details please
m_a_m_a [10]
Ok, first you need to read a - g and mark down the information you know. Also, this continuous function can look pretty much like anything long as it has the a - g constraints/rule. 

A) We know the domain(x values) is between -10 to infinity
(-10,-9,-8,-7,-6,-5,-4,-3-,2,-1,0,1,2,3,4,5,6,7,8,9,10, to ---------> infinity)
B) We know the range(y values) is between -6 to infinity
(-6,-5,-4,-3-,2,-1,01,2,3,4,5,6,7,8,9,10, to ---------> infinity) 

C) Next we know f(0) = f(4) = 0
So we know when x = 0  that f(0) = 0 or we can say  y = 0. We also know when f(4) = 0 so when x = 4 y = 0. So we have two points (0,0) and (4,0) that our function will be on so plot the two points (0,0) (4,0)

D) It tells us that f(x) (y) is increasing between the x values (-10,-6)  or (-2,2) or (4, to infinity)

E) It tells us that f(x) (y) is decreasing between the x values (-6,-2) or between (2,4)

F) Tells us that f(x) (y) is greater than or equal to between the x values of [-8,-4] or between the x values [0, to infinity) so this lets us know our drawing is going to be above or equal to 0 when we are in the values [-8,-4] or [0, to infinity)

G) Tells us that f(x) (y) is less than 0 when the function / drawing is between the x values of (-10, -8) or (-4,0)  

The picture is what the function could look like. It can be different but needs to following the rules that are given

What are the solutions of the equation x6 – 9x3 + 8 = 0? Use u substitution to solve. x = –1 and x = –2 x = 1 and x = 2
malfutka [58]
Let u=x^3
the original equation becomes: u^2-9u+8=0
factor this quadratic equation: (u-8)(u-1)=0
u=8, or u=1
that means x^3=8 or x^3=1
x=2  x=1
