Answer:

D. -1.5 cm/hour

Step-by-step explanation:

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Using the coordinates of the two points on the line, (0, 18) and (4, 12),

Let,

[tex] (0, 18) = (x_1, y_1) [/tex]

[tex] (4, 12) = (x_2, y_2) [/tex]

Plug the values into the formula for rate of change.

Rate of change = [tex] \frac{12 - 18}{4 - 0} [/tex]

[tex] = \frac{-6}{4} [/tex]

Simplify

[tex] = \frac{-3}{2} = -1.5 [/tex]

Rate of change = -1.5 cm/hour

Answer:

Unit rate = $ 30.

Step-by-step explanation:

Unit rate = Total cost ÷ Number of calculators

              = [tex]\frac{150}{5}[/tex]

             = $ 30

Answer:

$30 per calculator

Step-by-step explanation:

To find the unit rate of the calculators, take the total price of calculators and divide it by 5 to get 30.

This method works when finding any unit rate even when it doesn't involve prices.

*Tip* When dividing, write it as a fraction in case the quotient is not a whole number.

Answer:

x = 20

Step-by-step explanation:

Original Equation:

1/2x - 3 = 7

(1/2x can be written as 0.5x)

0.5x - 3 = 7

Add 3 to both sides.

0.5x = 10

Divide both sides by 0.5

x = 20

Answer:

-Angelina is correct

Explaintion: Jack in incorrect because it seems that he messed up is place order. He might have thought that 1 liter is equal to 100 mililiters instead of 1,000. That way he might have gotten 30+5=35  instead of 5+3=8

Step-by-step explanation:

3000 ML+ 5L

1 milliliter has 0.001 liters in it.

3000ML= 3L

Angelina has 8 lieters of water in the tub now.

Answer:

1.732

Step-by-step explanation:

.......................

Answer:

63%

Step-by-step explanation:

A percentage is x/100.  So 0.63 = x/100.  So multiply by 100, and you'll get 63%.

Answer:

Yes it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

Step-by-step explanation:

From the question we are told that

The population proportion is  p=0.4

  The sample size is  n =  39

  The sample proportion is  [tex]\^ p = 0.43[/tex]

Generally for normal approximation to be used

       [tex]np > 10[/tex]

so np  =  39 * 0.4 =  15.6 > 10

   and [tex]n(1- p) > 10[/tex]

so   n(1-p ) = 39(1-0.4) = 23.4 >10

Given that the both condition is meet it mean that  it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

Answer:

a

Step-by-step explanation:

i looked a the calculator

Answer:

trust me on this answer. It is D, a = 1, b = 2, c = 3

Step-by-step explanation:

Okay, so the problem is 5/8 divided by 3/8.

So, you find the reciprocal, which then is 5/8 x 8/3

Since there is an 8 is both the first denominator and the second numerator, you cross them out, which leaves you 5/3

So, 5 can go into 3, only 1 time.

5/3 = 3/3 + 2/3

So, 3/3 + 2/3 = 1 2/3

Therefore, D is the answer of choice.

Answer:

C. It supports the scientific explanation for global warming.

Explanation:

The listed pieces of empirical evidence support the scientific explanation for global warming. Global warming is the long-term heating of Earth's climate, and the increase in levels of carbon dioxide and methane is the reason why glacial ice in the Antarctic and Arctic sea is melting.

These pieces of evidence don't deal with the past of the future. They tell us what is going on right now. Based on them, we could make an assumption about what is going to happen in the future, but there are no predictions here.

Also, this data can be used for science journals and textbooks, but that purpose is not expressed here.

This leaves us with option C as the correct one.

Answer:

Step-by-step explanation:

1)

A. 2 meters to centimeters

1 m = 100 cm

[tex]2 m = 2 \times 100 \\2 m = 200 cm = 2 \times 10^2[/tex]

B)108 centimeters to meters

100 cm =1 m

[tex]1 cm = \frac{1}{100} m \\108 cm = \frac{108}{100}=108 \times 10^{-2} m[/tex]

C)2.49 meters to centimeters

1 m = 100 cm

[tex]2.49 m = 2.49 \times 100 = \frac{249}{100} \times 100 = 249 cm[/tex]

D)50 centimeters to meters

100 cm = 1m

[tex]1 cm = \frac{1}{100} m \\50 cm = \frac{50}{100}= 5 \times 10^{-1} m[/tex]

E)6.3 meters to centimeters

1 m = 100 cm

[tex]6.3 m = 6.3 \times 100=\frac{63}{10} \times 100 = 630 cm[/tex]

F)7 centimeters to meters

100 cm = 1 m

[tex]1 cm = \frac{1}{100} m\\\\7 cm = \frac{7}{100} = 7 \times 10^{-2} m[/tex]

2)

a)4 meters to millimeters

1 m = 1000 mm

[tex]4 m = 4000 = 4 \times 10^3 mm[/tex]

b)1.7 meters to millimeters

1 m = 1000 mm

[tex]1.7 m = 1.7 \times 1000= \frac{17}{10} \times 1000=17 \times 10^2 mm[/tex]

Answer:

The probability is [tex]P(X  \le 2 ) = 0.9072[/tex]

The company will accept 90.72% of the shipment and will reject [tex](100 -90.72) =  9.2\%[/tex] of the shipment , so many of the shipment are rejected

Step-by-step explanation:

From the question we are told that

   The  sample size is  n =  36

   The  proportion that did not meet the requirement is  [tex]p =  0.03[/tex]

Generally the probability that the whole shipment is accepted is equivalent to the probability that there is at most 2 batteries that do not meet the requirement , this is mathematically represented as

     [tex]P(X  \le 2 ) = [ P(X =  0 ) +  P(X =  1 ) + P(X = 0)][/tex]

=>   [tex]P(X  \le 2 ) = [ [^{n}C_0 * (p)^{0} *(1-p)^{n-0} ] +  [^{n}C_1 * (p)^{1} *(1-p)^{n-1} ] +  [^{n}C_2 * (p)^{2} *(1-p)^{n-2} ]][/tex]

Here C stands for Combination (so we will be making the combination function in our  calculators )

So

=> [tex]P(X  \le 2 ) = [ [^{36}C_0 * (0.03)^{0} *(1-0.03)^{36-0} ] +  [^{36}C_1 * (0.03)^{1} *(1-0.03)^{36-1} ] +  [^{36}C_2 * (0.03)^{2} *(1-0.03)^{36-2} ]][/tex]

=> [tex]P(X  \le 2 ) = [ [1 * 1 * 0.3340  ] +  [36* 0.03 *0.3444 ] +  [630 * 0.0009 *(0.355 ]][/tex]

=>[tex]P(X  \le 2 ) = 0.9072[/tex]

The company will accept 90.72% of the shipment and will reject [tex](100 -90.72) =  9.2\%[/tex] of the shipment , so many of the shipment are rejected
