Answer:

conversion factor

Step-by-step explanation:

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

Step-by-step explanation:

Answer:

60 ounces.

Step-by-step explanation:

A chain weighs 9 pounds per foot.

We are to find the number of ounces 5 inches weigh.

First we find how many feet are in 5 inches.

1 foot = 12 inches

how many feet? = 5 inches.

Cross-multiplying gives;

[tex]\frac{5}{12} * 1 = \frac{5}{12}[/tex]   feet

1 foot of the chain = 9 pounds

[tex]\frac{5}{12}[/tex] feet = how many pounds?

Cross-multiplying gives;

[tex]\frac{5}{12} * 9 = 3.75[/tex] pounds

1 pound = 16 ounces

3.75 pounds = how many ounces?

Cross-multiplying gives;

[tex]\frac{3.75 * 16}{1} = 60[/tex] ounces.

The number of ounces will 5 inches weigh is 66.667 oz.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A chain weighs 9 pounds per foot.

We know that

1 foot = 12 inches.

1 pound = 16 ounces.

Now based on this,

= 5 inches 1/12 x foot/ inches x 10 x pound/ feet x 16

= 5 x 10 x 16 / 12

= 66.667 oz.

Hence, the chain weight 66.6667 oz.

Answer:

770 cm :)

Step-by-step explanation:

1m is 100cm so just multiply 7.7 by 100

The tree in Juan's backyard is 7.7 m high.

How high is it in cm.

1 m = 100 cm

7 m = 7 × 100 = 700 cm

7.7 m = ( 700 + 70 ) cm = 770 cm

770 cm

Therefore, it is 770 cm high.

The following are the solution to this question:

Step-by-step explanation:

In the given question, some of the values are missing which is defined in the attached file please find it.

In this question, the data is used to represent a standardized​ exam's scores, which is normally spread out into the test score that is  1530 and its standard deviation 316.  

Formula:

[tex]\to z=\frac{X- \mu}{\sigma } \\[/tex]

If the value of z-score= 1930

       [tex]\to z =\frac{1930- 1530}{316 } \\\\ \to z =\frac{400}{316 } \\\\ \to z = 1.27[/tex]

The z-score is 1.27

If the value of z-score= 1250

       [tex]\to z =\frac{1250- 1530}{316 } \\\\ \to z =\frac{-280}{316 } \\\\ \to z = -0.886[/tex]

The z-score is -0.886

If the value of z-score= 2250

       [tex]\to z =\frac{2250- 1530}{316 } \\\\ \to z =\frac{720}{316 } \\\\ \to z = 2.27[/tex]

The z-score is = 2.27

If the value of z-score= 1420

       [tex]\to z =\frac{1420- 1530}{316 } \\\\ \to z =\frac{-110}{316 } \\\\ \to z = -0.348[/tex]

The question is missing some parts. Here is the complete question.

A technician compares repair costs for two types of microwave ovens (type I and type II). He believes that the repair cost for type I ovens is greater than the repair cost in type II ovens. A samplle of 61 type I ovens has a mean repair cost of $79.60, with a standard deviation of $23.47. A sample of 45 type II ovens has a mean repair cost of $75.25, with standar deviation of $15.07. Conduct a hypothesis test of the technician's claim at the 0.05 level of significance. Let [tex]\mu_{1}[/tex] be the true mean repair cost for type I ovens and [tex]\mu_{2}[/tex] be the true mean repair cost for type II ovens.

Step 1 of 4: State null and alternative hypothesis for the test.

Step 2 of 4: Compute the value of test statistics. Round your answer to 2 decimal places.

Step 3 of 4: Determine the decision rule for rejecting the null hypothesis. Round the numerical portion of your answer to 3 decimal places.

Step 4 of 4: Make the decision for the hypothesis test. (Reject or fail to reject Null Hypothesis)

Answer and Step-by-step explanation:

First, state null and alternative hypothesis:

[tex]H_{0}: \mu_{1}=\mu_{2}[/tex]

[tex]H_{a}: \mu_{1}>\mu_{2}[/tex]

Use z-statistics:

[tex]z = \frac{x_{1}-x_{2}}{y}[/tex]

where x₁ and x₂ are the means and:

[tex]y=\sqrt{\frac{s_{1}^{2}}{n_{1}}+\frac{s_{2}^{2}}{n_{2}} }[/tex]

Calculating value of test stattistic:

[tex]y=\sqrt{\frac{(23.47)^{2}}{61}+\frac{75.25^{2}}{45} }[/tex]

[tex]y = \sqrt{9.030+5.046}[/tex]

[tex]y = \sqrt{14.076}[/tex]

y = 3.752

[tex]z = \frac{79.6-75.25}{3.752}[/tex]

z = 1.16

The test statistics is z = 1.16

The decision rule for rejecting null hypothesis is: [tex]\alpha[/tex] ≤ test statistics

Using z-score table, it is possible to determine p-value, which is:

p-value = 0.877

Comparing p-value with level of significance (α = 0.05):

0.877 > 0.05

Therefore, we fail to reject the null hypothesis.

Answer:

Step-by-step explanation:

(12x − 36) = 5x + 18

First of all remove the parenthesis

That's

12x - 36 = 5x + 18

Next subtract 5x from both sides of the equation

We have

12x - 5x - 36 = 5x - 5x + 18

7x - 36 = 18

Add 36 to both sides of the equation

That's

7x + 36 - 36 = 18 + 36

7x = 54

Divide both sides by 7

[tex] \frac{7x}{7} = \frac{54}{7} [/tex]

We have the final answer as

[tex]x = \frac{54}{7} [/tex]

Hope this helps you

Answer: x=54/7

Step-by-step explanation:

To find the value of x, we need to use algebraic properties to isolate x.

12x-36=5x+18         [subtract both sides by 5x]

7x-36=18                  [add both sides by 36]

7x=54                      [divide both sides by 7]

x=54/7

Now, we know that x=54/7.

Answer:

[tex]m \geq 1166[/tex]

Step-by-step explanation:

Given

[tex]Base\ Amount = \$24[/tex]

[tex]Charges = \$0.06[/tex] per minute

[tex]Least\ Monthly\ Charges = \$93.96[/tex]

Required

Determine the possible number of minutes

If for 1 minute, he's charged $0.06;

He'll be charged $0.06m for m minutes

Representing this as an inequality, we have:

[tex]Base\ Amount + m\ Charges \geq\ Least\ Monthly\ Charges[/tex]

[tex]24 + 0.06m \geq 93.96[/tex]

Solve for 0.06m

[tex]0.06m \geq 93.96 - 24[/tex]

[tex]0.06m \geq 69.96[/tex]

Solve for m

[tex]m \geq 69.96/0.06[/tex]

[tex]m \geq 1166[/tex]

This implies that, he's charged for at least 1166 minutes

Step-by-step explanation:

Let's say c is the price of cinnamon tea, and s is the price of spice tea.

10c + 2s = 13

16c + 8s = 28

Divide the second equation by 4:

4c + 2s = 7

Subtract from the first equation:

6c = 6

c = 1

Use any equation to find s.

s = 1.5

Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.
