Step-by-step explanation:

In order to solve this you just have to put together the numbers witht the same base and exponent and then you just add and withdraw, and you can do it like this:

""7x^3-x^2+1\\+x^3+2x^2+2\\\\------\\8x^3+ x^2+3

So the answer would be :8x^3+x^2+3

Convert the following equation into<br> standard form.
kicyunya [14]

Answer:

7x+9y=45

Step-by-step explanation:

Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.

Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read \frac{7}{9} x + y = 5

Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.

Assume that the data has a normal distribution and the number of observations is greater than fifty. Find the critical z value u
Alenkasestr [34]

Answer:

The  value is  1.75 \  and  \   -1.75

Step-by-step explanation:

From the question we are told that

     The null hypothesis is  H_1 :  \mu \ne 3.24

     The level of significance is  \alpha = 0.08

From the z table  the critical value of  \alpha considering the two tails of the normal  curve( This is because this a two tailed test ) is

       z= \pm  1.75

Hence the critical value is  

       1.75 \  and  \   -1.75
