Answer:

20 - 10 cm sections can be cut from a pipe of original length 2 m

Step-by-step explanation:

Convert 2 meters to cm:  

2 m       100 cm

------ * ---------------- = 200 cm

  1             1 m

Next, divide this 200 cm total length by (10 cm/section) to determine the number of sections:

200 cm

--------------------- = 20 sections

10 cm/section

20 - 10 cm sections can be cut from a pipe of original length 2 m

3x-4y=0 2x+y=110 no solution
weeeeeb [17]

Answer:

  (x, y) = (40, 30)

Step-by-step explanation:

A graphing calculator can show you the solution to this system of equations is (x, y) = (40, 30). That is the point of intersection where the two lines cross.

__

An algebraic solution can be found by using the substitution method. An expression for y can be found using the second equation:

  y = 110 -2x . . . . . . subtract 2x from both sides

Using this in the first equation gives ...

  3x -4(110 -2x) = 0 . . . . substitute for y

  11x = 440 . . . . . . . . . simplify, add 440

  x = 40 . . . . . . . . . . divide by 11

  y = 110 -2(40) = 30

The solution is (x, y) = (40, 30).

Colt1911 [192]

Answer:

24.

Step-by-step explanation:

Basically constant of proportionality is a ratio.

We take two points, we'll take the order pair (2,48)

It will always be y/x so y is 48 and x is 2

48/2    -  now we simplify

answer: 24

hope this helps! :))

A phone manufacturer wants to compete in the touch screen phone market. He understands that the lead product has a battery life
Tasya [4]

Answer:

(a) <em>H₀</em>: <em>μ</em> ≤ 10. vs. <em>Hₐ</em>: <em>μ</em> > 10.

(b) The test statistic value is 1.86.

(c) The critical value to test the phone manufacturer's claim is 1.301.

(d) The battery life of the new touch screen phone is not more than 10 hours.

Step-by-step explanation:

In this case we need to determine the significance of the claim made by the phone manufacturer, that the battery life of the new touch screen phone is more than twice as long as that of the leading product.

The information provided is:

\bar x=10.5\\s=1.8\\n=45

(a)

The hypothesis can be defined as follows:

<em>H₀</em>: The battery life of the new touch screen phone is not more than 10 hours, i.e. <em>μ</em> ≤ 10.

<em>Hₐ</em>: The battery life of the new touch screen phone is more than 10 hours, i.e. <em>μ</em> > 10.

(b)

As the population standard deviation is not provided, we will use a <em>t</em>-test for single mean.

Compute the test statistic value as follows:

 t=\frac{\bar x-\mu}{s/\sqrt{n}}=\frac{10.5-10}{1.8/\sqrt{45}}=1.86

The test statistic value is 1.86.

(c)

The significance level of the test is, <em>α</em> = 0.10.

The degrees of freedom will be:

df=n-1=45-1=44

Compute the critical value as follows:

t_{0.10, 44}=1.301

*Use a <em>t</em>-table for the value.

Thus, the critical value to test the phone manufacturer's claim is 1.301.

(d)

Decision rule:

If the test statistic value is less than the critical value then the null hypothesis will be rejected and vice-versa.

 t = 1.86 > t₀.₁₀, ₄₄ = 1.30

The calculated <em>t</em>-value of the test is more than the critical value.

The null hypothesis will not be rejected.

Thus, it can be concluded that the battery life of the new touch screen phone is not more than 10 hours.

Please help meh plss
iragen [17]

Answer:

A, B

Step-by-step explanation:

Point C is greater than point B is correct, point C lies at 1.5.

1.5 is greater than 0.

Point B is less than 1 is correct, point B lies at 0.

0 is less than 1.

A number added to 8 times that numbers reciprical is 6, find the number
castortr0y [4]
Call your unknown number x.  The reciprocal would be1/xYou are supposed to add your unknown number to 8 times its reciprocal, orx+8(1/x)This is all supposed to equal 6, so you havex+8/x=6
Solve for x to get your number.
n + 8(1/n) = 6n^2 + 8 = 6nn^2 - 6n + 8 = 0(n - 4)(n - 2) = 0n = 2, 4
So 2 and 4 both are answers in my opinion.
