Express the sum of the 2 polynomials by removing the parenthesis , so

5 $x^{5}$ - 2x³ + x + 4 $x^{5}$ - 3 $x^{4}$ + 2x³ - 5x ← collect like terms

= 9 $x^{5}$ - 3 $x^{4}$ - 4x

5(5t + 1) = 25t-7<br> Can someone help me with this solution??

masha68 [24]

Firstly you multiply 5 with everything in the brackets on the left side of = . and than you put t on the left side and change sign (if it was + then its going to be -) and numbers on right side and do the same with signs. then just calculate the rest

5(5t +1) = 25t - 7
25t + 5 = 25t - 7
25t - 25t = -7 + 5
0=-2
the statement is false

UNO [17]

Answer:

we reject H₀

Step-by-step explanation: Se annex

The test is one tail-test (greater than)

Using α = 0,05 (critical value ) from z- table we get

z(c) = 1,64

And Test hypothesis is:

H₀ Null hypothesis μ = μ₀

Hₐ Alternate hypothesis μ > μ₀

Which we need to compare with z(s) = 2,19 (from problem statement)

The annex shows z(c), z(s), rejection and acceptance regions, and as we can see z(s) > z(c) and it is in the rejection region

So base on our drawing we will reject H₀
