b. Graph the pairs of values.

Answers

Answer:

after 42 mm the next one is 63mm and after 198mm it is 946mm

Step-by-step explanation:

The Diameter of the second circle is 63 mm and the circumference of the third circle is 946.

What is circumference?

The circumference of a circle is the distance along a line across it. In other words, the length of a straight line created by opening a circle matches the radius of the circle. The formula to calculate circumference is C = π * Diameter.

Given that circumference of the first circle is 198mm by that we can drive the value of the diameter(D₂). from the formula of the circumference

C = π D₂

198 = 3.14 * D₂

D₂ = 63mm.

Given that the Diameter of the first circle is 198mm by that we can drive the value of the circumference. from the formula of the circumference

C₃ = π D₃

C₃ = 3.14 * 301

C₃ = 946 mm.

Therefore, the missing dimensions of the circular object are D₂ is 63mm and C₃ is 946mm.

For which sample size (n) and sample proportion (p) can a normal curve be
used to approximate the sampling distribution?

Answers

Answer:

Option c.

Step-by-step explanation:

Using the normal curve to approximate a sampling distribution:

For a sample size n and a proportion n, the normal curve can be used if:

[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]

Option a:

[tex]np = 35*0.8 = 28 > 10[/tex]

[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]

So option a cannot be used.

Option b:

[tex]np = 65*0.9 = 58.5 > 10[/tex]

[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]

So option b cannot be used.

Option c:

[tex]np = 65*0.8 = 52 > 10[/tex]

[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]

So option c can be used, and is the answer

Option d:

[tex]np = 35*0.9 = 31.5 > 10[/tex]

[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]

So option d cannot be used.

The answer is given by option c.

If x represents the age of the father and
y represents the present age of the son,
then the statement for 'present age of
the father is 5 more than 6 times the
age of the son' in terms of a
mathematical equation is *

Answers

Answer:

x = 5+6y

Step-by-step explanation:

Let x represents the age of the father and y represents the present age of the son.

ATQ,

The present age of the father is 5 more than 6 times the age of the son. We can write it in the form of equation as follows :

6 times the age of the son means 6y. So,

x = 5+6y

Hence, the mathematical equation is "x = 5+6y".

1. Sarah's current account balance is $2,600. She made a single lump sum amount of
$2,000 eight years ago into the account. Calculate the equivalent simple interest
rate (quoted annually) that she earned.

Answers

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.

Please help! What is the answer?

Answers

Answer: 6.4cm

Step-by-step explanation:

The area of a trapezoid is given as:

= 1/2(a + b)h

We then slot the given values into the formula. This will be:

1/2(15.8 + b) × 7.3 = 81.03.

7.3(15.8 + b)= 81.03 × 2

7.3(15.8 + b) = 162.06

115.34 + 7.3b = 162.06

7.3b = 162.06 - 115.34

7.3b = 46.72

b = 46.72/7.3

b = 6.4

Therefore, the answer is 6.4cm.

Find the area of this composite figure

Answers

Answer:

23.9425 (Round if needed)

Step-by-step explanation:

This is 2 half circles so you can find the area of a circle and divide it by 2.

First circle has a diameter of 6 cm

6/2=3 cm

So, circle has radius of 3.

Area of circle= 3.14(pi) radius^2

3.14 x 3^2= 28.26

28.26/2=14.13 cm

Area of first half circle= 14.13

Repeat that process for the second circle.

3.14 x 2.5^2=19.625

19.625/2=9.8125

14.13+9.8215=23.9425

Area=23.9425

Look in your grocery bag the next time you come home from shopping, and just count all the boxes and packages. Although it is good to put pressure on manufacturers by writing letters and urging them to use recyclable packaging, this is more like a Band-Aid for the problem. Even if all the packaging were recyclable, it still requires energy to turn the used containers back into usable items. The only real solution is one that is particularly hard for us because it necessitates a change in lifestyle. We quite simply have to get back to basics and learn to live on more fresh foods as well as staples we can buy in bulk, like rice and other grains. It also means passing up that yummy tofu salad in the deli case and making it yourself at home. Likewise, it means not getting take-out food or at least getting it far less often. By doing this, we not only greatly reduce our own need to recycle used materials, but we put pressure on manufacturers at the same time. If we quit buying their wares, they will have to make changes, such as using containers that can be composted. Of course, it is good to write letters, too. That way the companies understand exactly why you have stopped buying their products. Then, they will know what they need to change to entice you back to using their products.Which of the following lines features the author's proposed method of creating change in the manufacturing and pachaging industries?No answer provideda.
