Answer:

x=8

Step-by-step explanation:

1. Multiply both sides by ten

x/10*10 and 4/5*10

*****Multiplying x/10 by 10 cancels it out and only leaves X. So x/10*10 equals X and 4/5*10 equals 8.

2. Put that together and X=8!

I hope I've helped! Plz leave a Thanks and Rate!

I have already tryed but how in the world do i solve 2

Alright, let's factor this to get the answer.
3k^2-10k+7
To find the factors, we want to think "What will add up to -10, and multiply to (+)7?"
Because the leading coefficient is 3, we know that we can take one factor of 7 and multiply it by 3.
Thus, this factors to
(3k-7)(k-1)
(if you FOIL it it should come out to be the original equation)

From this, set both of those [(3k-7) and (k-1)] equal to zero and solve
3k-7=0
3k=7
/3
k=7/3
or
k=1

Find the P-value for the indicated hypothesis test with the given standardized test statistic, z. Decide whether to reject H0

Leviafan [203]

Answer: We do not reject the null hypothesis.

Step-by-step explanation:

When the p-value is greater than the significance level , then we do not reject the null hypothesis or if p-value is smaller than the significance level , then we reject the null hypothesis.

Given : Test statistic : $z = -2.28$
