6 0

Step-by-step explanation:

Start with a point on (0,6) This is because the 6 represents the point on the y - axis

Then, move up 1 and 3 to the right; This should result with a point on (3,7)

Keep repeating this to get your line

2x+3y=11<br> Solve for x and y
irga5000 [103]
To solve this equation you have to isolate one variable, first we will solving for x, then for y.

Solving for x

2x+3y=11

2x=11-3y

\boxed{\boxed{x=\frac{11}{2}-\frac{3}{2}*y}}

Solving for y

2x+3y=11

3y=11-2x

\boxed{\boxed{y=\frac{11}{3}-\frac{2}{3}*x}}

A newsletter publisher believes that 55% of their readers own a Rolls Royce. Is there sufficient evidence at the 0.05 level to r
melomori [17]

Set up hypotheses:

The null hypotheses is that the proportion of readers who own a Rolls Royce is equal to 0.55

Null hypotheses = H₀: p = 0.55

The alternate hypotheses is that the proportion of readers who own a Rolls Royce is not equal to 0.55

Alternate hypotheses = H₁: p ≠ 0.55

Determine the  type of test:

Since the alternate hypothesis states that the proportion of readers who own a Rolls Royce is different, therefore it is a two-tailed test.

Determine the level of significance and Critical Z-score:

Given level of significance = 0.05

Since it is a two-tailed test,

Z-score = 1.960 (two tailed)

Set up decision rule:

Since it is a two-tailed test, using a Z statistic at a significance level of 5%

We Reject H₀ if Z < -1.960 or Z > 1.960

We Reject H₀ if p ≤ α

Compute the test statistic:

The test statistic may be calculated using,

$ Z =  \frac{\hat{p} - p}{ \sqrt{\frac{p(1-p)}{n} }}  $

We are not given enough information to find out the test statistic.

Conclusion:

We do not have enough information to accept or refuse the publisher's claim.

Nick has a new pool in his backyard in the shape of a rectangle. He needs to buy a cover for the winter months. Nick knows that
Natalka [10]

Answer:

1. Show the formula to determine the area of a rectangle.

area = length x width

2. Rearrange the formula to find the unknown length of Nick's pool

length = area / width

3. Calculate the length of Nick's pool.

length = 384 / 16 = 24 feet

4. If Nick had to buy a cover that was too long (30 foot), how much extra area would be left over after the pool is covered?

(30 - 24) * 16 = 6 * 16 = 96 square feet

A company is interested in testing sample sets of 20 Widgets to see how they withstand a heat test. Widgets fail the heat test w
Andreyy89

Answer:

Discrete Distribution.

Step-by-step explanation:

For each widget, there are only two possible outcomes. Either they develop paint cracks, or they do not. The probability of a widget developing paint cracks is independent of any other widgets, which means that the binomial probability distribution, which is a discrete distribution, is used to solve this question. Thus the answer is a Discrete Distribution.
