Solve algebraically -x+y=4

1 answer:

4 0

You did not include instructions but I think you want to solve for y.
To do so, we isolate y.
Add 4 from both sides as step 1.
-y - 4 + 4 = 12 + 4
On the left side, -4 and +4 cancel out.
We now have this:
-y = 16
Next, divide both sides by -1.
Final answer: y = -16

Prior to a special advertising campaign, 23% of all adults recognized a particular companyâs logo. At the close of the campaign

Answer:

The answer is "2.4049"

Step-by-step explanation:

Calculating the test of Hypothesis: $H_{0}: 23\% \ \text{off all adults which reconize the compony's logo}\\\\H_{1}: \text{more than 23\% of adult recornise the compony's logo}\\\\$

that is

$H_{0}: p=0.23\ against \ H_{1}:p>0.01\\\\Z=\frac{P-p}{\sqrt{\frac{p(1-p)}{n}}}\sim N(0,1)\\\\$

Given:

$p= 0.23\\\\ \therefore \\\\1-p=0.77\\\\n=1200\\\\ P=\frac{311}{1200}=0.2591\\\\\therefore\\\\Z= \frac{0.2591-0.23}{\sqrt{((0.23)\times \frac{(1-0.23))}{1200}}}=2.4049$

Z=2.576 tabled value. Because Z is 2.4049, that's less than Z stated, there is no indication that a null hypothesis is rejectable, which means that 23% of all adults record the logo of the Company.

Kathleen bought 4 dresses that each cost the same amount and pair of jeans that cost $40. The items she bought cost a total of $

stepan [7]

Each dress would be $30 because, if you do 160-40 = 120 then 120 divided by 4 = 30. So that’s the answer 30
