If a lost male child is found who is 145 cm tall, determine an interval of likely ages for the child.

Answer:

7

Step-by-step explanation:

So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4

adding this all up we get 8x-7=49, so 8x = 56 or x = 7

Answer:

approximately 10 times

Step-by-step explanation:

It is expected that a vowel will be spun approximately 10 times.

Spinner is divided into 6 equal sectors labeled with the alphabets A to F

We know that, the vowels in english are A, E, I, O, U.

In between A and , there are 2 vowels, A and E.

Probabilty of getting vowel in 1 spin = [tex]\frac{2}{6}[/tex] = [tex]\frac{1}{3}[/tex] = 0.33

The spinner is spun 30 times.

It is expected that a vowel will be spun =  0.33 × 30 times

                                                                 = 9.9 times = 10 times (approx)

If the copy machine prints 175 pages in 5 minutes and the number of pages printed is proportional to the time in minutes , the unit rate is 35 pages per minute.

Division is the process of determining the quotient of a number. It is the process of grouping a number into equal parts using another number.

The unit rate can be determined by dividing 175 by 5

Unit rate = 175/5 = 35 pages per minute.

Answer:

C.

Since the square root of 20 is around 4.5, we know that ≈4.5 is almost at the half mark between 4 and 5 on the number line.

The probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

It is defined as the diagram that shows a logical relation between sets.

The Venn diagram consists of circles to show the logical relation.

We have:

f = 100 stamps in the collection

A = stamps in the 20th century

B = British stamps

We can make a linear equation to solve for x as the total stamps are 100 in the collection.

[tex]\rm x(x-6)+x+2x+32= 100\\\\\rm x^2-6x+x+2x+32 = 100\\\\\rm x^2-3x-68 = 0[/tex]

After solving x = 9.88, or x = -6.88

Probability can't be negative so neglecting the negative ones

x = 9.88

The probability that it is British:

[tex]=\rm \frac{x +2x + 32}{100}[/tex]  

[tex]=\rm \frac{9.88 +2(9.88) + 32}{100}[/tex]

= 61.64/100

= 0.6164

Thus, the probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

Answer:

Step-by-step explanation:

First find the surface area of the clyinder and find the area circles and subtract

Then find the surface area of a cone, remove the circle area and double it.

Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741

251.32741 - 50.2 - 50.2

Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734

113.09734 - 50.2 - 50.2

Total: 12.69734 + 150.92741 = 163.62475

Answer: 190 m³

Step-by-step explanation:

    We will calculate the volume of the prisms separately, and then add them together.

V = L * W * H

   [1]

V = L * W * H

V = 9 * 2 * 5

V = 90 m³

   [2]

V = L * W * H

V = 5 * 5 * 4

V = 100 m³

   [Adding together]

100 + 90 = 190 m³

               The volume is 190 m³
