So we can setup variable equations for this:
so we're given that the length is 22feet longer than the width!
so as an expression length is equal to 22+w
and width as an expression is just w
so the formula for the perimeter for a rectangle is 2l+2w=perimeter
so fill it in now!
1616=2(22+w)+2w
1616=44+2w+2w
1616=44+4w
1572=4w
divide by four..
w=393
and length is simply 22 more than that as stated in the question!
so length is 415
dimensions are: 415x393

777dan777 [17]

Answer:

a. There are 48 angelfish.

b. There are 36 goldfish.

Step-by-step explanation:

the ration of clownfish to angelfish is 5:4 and there are 60 clownfish.

60:? 5x=60 x=12 12(4)=48

60:48 there are 48 angelfish

the ration of angelfish to goldfish is 4:3 and know we know there are 48 angelfish

48:? 4x=48 x=12 12(3)=36

48:36 there are 36 goldfish

Ivenika [448]
When x=0, y=-8, so that is the y-intercept.

When x increases by 1, y decreases by 2, so the slope is -2.

The equation of the function is
.. y = -2x -8

Suppose a researcher is testing someone to see if he or she can tell Soda X from Soda​ Y, and the researcher is using 28 ​trials
AlladinOne [14]

Answer:

The probability that a person will get 17 or more​ right, if the person is truly​ guessing, is about 12.9%.

The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.

Step-by-step explanation:

The system of hypothesis fo this case are:

Null hypothesis: p\leq 0.5

Alternative hypothesis: p >0.5

That's a upper right tailed test.

The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.

And this value allows to reject or not the null hypothesis.

If p_v we reject the null hypotheis at the significance level. That indicates strong evidence against the null hypothesis, so you reject the null hypothesis.

If p_v>\alpha then we say that we fail to reject the null hypothesis at the significance level. That indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
