Answer:

Step-by-step explanation:

Given equation of the line is,

y = 2x + 1

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = Slope of the line = 2

b = y-intercept = 1

Table for the input - output values,

x -1 0 1 2

y -1 1 3 5

Now graph these points on the graph and join them by a straight line.

In the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37

djyliett [7]

Answer:

More than 50% would germinate

Step-by-step explanation:

Given that in the production of a plant, a treatment is being evaluated to germinate seed. From a total of 60 seed it was observed that 37 of them germinated

Let us check whether more than 50% will germinate using hypothesis test

$H_0: p = 0.50\\H_a: p>0.50\\$

(right tailed test)

Sample proportion p = $\frac{37}{60} =0.617\\q = 0.383\\Std error = \sqrt{\frac{pq}{n} } =0.0628$

p difference = 0.117

Test statistic Z = p difference/std error = 1.864

p value =0.0312

Since p value <0.05 our significance level of 5% we reject null hypothesis

It is possible to claim that most of the seed will germinate (i.e. more than 50%)

Leigh has a piece of rope that is 6 2/3 feet long. How do you write 6 2/3 as a fraction greater than 1

aleksley [76]

20/3 - Take the 6 2/3, multiply the 6 and the 3 (6 x 3 = 18), then add the 2 (18 + 2 = 20). Put that number over the original 3 and you've got yourself a mixed number.

Find the product. 8y 3(-3y 2)

S_A_V [24]

For this case we must find the product of the following expression:

$8y ^ 3 (-3y ^ 2) =$

We have to by law of signs of multiplication:

$+ * - = -$

Also, by definition of multiplication of powers of the same base, we put the same base and add the exponents, then the expression is rewritten as:

$-24y ^ {3 + 2} =\\-24y ^ 5$

Answer:

$-24y ^ 5$

What is the midpoint of a segment in the complex plane with endpoints points a 3-2 I and 17 - 8 I

SCORPION-xisa [38]

Answer:

(10,51)

Step-by-step explanation:

Take the average of 3 (x1) and 17(x2). This will be your new x-coordinate.

Then take the average of 21 (y1) and 81 (y2)

(3+17)/2 = 10

(21+81)/2 = 51

Screen printing a batch of shirts takes 0.4 minutes to make a shirt in addition to 4 minutes of initial set time. If it take 6.4

uranmaximum [27]

There are 6 shirts in the batch

Step-by-step explanation:

The given is:

1. Screen printing a batch of shirts takes 0.4 minutes to make a shirt

2. The initial set time is 4 minutes

3. It takes 6.4 minutes to screen-print a batch of shirts

We need to find how many shirts are in the batch

Let us represent these information in a function

Assume that there are n shirts in the batch

Then t(n) is the total time to screen-print n shirts in the batch

∵ There is initial set time = 4 minutes

∵ It takes 0.4 minutes to make a shirt

∵ The number of shirts = n

∴ t(n) = 0.4 n + 4

∵ It takes 6.4 minutes to screen-print a batch of shirts

∴ t(n) = 6.4

∵ t(n) = 0.4 n + 4

∴ 6.4 = 0.4 n + 4

- Subtract 4 from both sides

∴ 2.4 = 0.4 n

- Divide both sides by 0.4

∴ n = 6

There are 6 shirts in the batch
