3. Which number is a natural number?
A-2.5
B 5-151
C-13+51
D|-81-2

Answers

Answer 1

Answer:

C

Step-by-step explanation:

A natural number is a number that you would use to count kids in a class for example. Like, 1,2,3,4 and so on. 2.5 is not a natural number since there cant be 2.5 of a student. 5-151 is a negative number and there cant be negative students. -13+51=38. 38 is a natural number. Now, in D it looks like there mightve been a absolute value sign but im not sure. If D has absolute value signs then D works too. Hope I could help.

Another teacher decides to average the height of all 15-year-old male students in his classes throughout the day. By the end of the day, he measured the height of 57 boys and calculated an average of 68.1 inches. The known mean height for 15-year-old boys is 67 inches, with a standard deviation of 3.19 inches. What is the percentile rank for this sample? (enter a number only, rounded to the nearest 2 decimal places)

Answers

Answer: 0.47

Step-by-step explanation:

0.47% = 0.0047 in decimal form. Percent means 'per 57'. So, 67Inches means 0.47 per 100 or simply 0.47/100. If you divide 0.47 by 100, you'll get 0.0047 (a decimal number).

A team of biologists captured and tagged 65 deer in a forest. Two weeks later, the
biologists captured a sample of 30 deer from the same forest and found that 5 of
them were tagged. Which proportion could be used to estimate the number of deer in
the forest?

Answers

Answer:

1/6x= 65

Step-by-step explanation:

so we can assume that 5/10= 1/6 of the deer were tagged

lets call the total number of dear x

so 1/6x= 65

x= 380

The proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

To estimate the number of deer in the forest, we can set up a proportion using the tagged deer in the sample as a representative of the entire population.

Let's denote the number of deer in the forest as 'x'.

We know that 65 deer were tagged out of the total population. In the sample of 30 deer, 5 were tagged.

Therefore, we can set up the following proportion:

Tagged deer in sample / Total deer in sample = Tagged deer in population / Total deer in population

5 / 30 = 65 / x

Now we can cross-multiply to solve for x:

5x = 65 * 30

5x = 1950

Dividing both sides by 5:

x = 1950 / 5

x = 390

Therefore, the proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

The perimeter of a rectangle is 50 centimeters. If the width of the rectangle is 9 centimeters
less than the length, find the dimensions of the rectangle.
Yes

Answers

Answer:

Length = 17 cm

Width = 8 cm

Step-by-step explanation:

Let the length be x cm

Therefore, Width = (x - 9) cm

Perimeter of rectangle = 2(l +w)

50 = 2[x + (x - 9)]

50/2 = 2x - 9

25 = 2x - 9

25+ 9 = 2x

2x = 34

x = 34/2

x = 17 cm

x - 9 = 17 - 9 = 8 cm

Therefore,

Length = 17 cm

Width = 8 cm

Thus, the dimensions of the rectangle are 17 cm and 8 cm.

12 years ago, a mother was twice as old as her son. their present age are in the ratio of 14:9. find their present ages.​

Answers

Answer:

The presents age of the mom is 42 years old, and of the son is 27 years old.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

The mothers age is x.

The son's age is y.

12 years ago, a mother was twice as old as her son.

This means that:

[tex]x - 12 = 2(y - 12)[/tex]

[tex]x = 2y - 24 + 12[/tex]

[tex]x = 2y - 12[/tex]

Their present age are in the ratio of 14:9.

This means that:

[tex]\frac{x}{y} = \frac{14}{9}[/tex]

[tex]14y = 9x[/tex]

Since [tex]x = 2y - 12[/tex]

[tex]14y = 9(2y - 12)[/tex]

[tex]18y - 108 = 14y[/tex]

[tex]4y = 108[/tex]

[tex]y = \frac{108}{4}[/tex]

[tex]y = 27[/tex]

[tex]x = 2*27 - 12 = 54 - 12 = 42[/tex]

The presents age of the mom is 42 years old, and of the son is 27 years old.

Here are the ingredients needed to make 8 pancakes
250ml milk
140 g flour
5 g butter
a) Simon makes 4 pancakes.

Answers

Answer: To make 4 pancakes, Simon will need 125 ml milk, 70 grams flour, and 2.5 grams of butter.

Step-by-step explanation:

If that is the recipe to make 8 pancakes, and Simon has 4 pancakes, then Simon needs to cut the recipe in half. So we can multiply each ingredient by 1/2.

250 x 1/2 = 125.

140 x 1/2 = 70.

5 x 1/2 = 2.5

In conclusion, to make 4 pancakes, Simon will need 125 ml milk, 70 grams of flour, and 2.5 grams of butter.
