!!Giving 15 points and will give brainliest!!Use the second list of random numbers to again calculate the experimental probability of a group having at least three girls. The results using the second list are
10%
the results using the first list.

Answers

Answer 1

Answer:

39% chance for only boys, 61% chance for only girls for the first two questions

the second is a bit trickier,you need a ratio for finding how many would be in 224 groups.

100:224 = 61:x, or 61/100 = x/224

Cross multiply; 100x=13664

Then, divide by 100; x=136.64, or about 137 groups would contain all girls

Step-by-step explanation:

Answer:

2.1 Yards of Black Material.

Step-by-step explanation:

The problem is a simple multipication problem.

Take 1.75, and multiply that by 1.2. The answer comes out to 2.09. Since the 9 in the .09 part is above 5, you would round that up, which gets you the answer of 2.1 Yards.

I think it’s 16 and 8

Answer:

16/8

Step-by-step explanation:

All you have to do to calculate the size of the new shape is take both numbers and multiply them by 4

The width is 4 inches, so

4x4=16

The height is 2 inches, so

2x4=8

If you're wanting to calculate the area of the new shape, just multiply 16 by 8.

16x8=128

If you need to calculate the perimeter of the shape, do this

16+16+8+8=48.

Hope this helped!

the boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the model.

please help!!!

Answers

answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684

36m because 250 divided by 8=36m

If line segment AB is 400%, what is the length of a line segment that is 100%?
_____ inch(es)
(Type a whole number or a decimal) ​

Answers

4 divided by 4, equals 1 so that means that 100% out of 400% of the line is equal to 1 inch

If line segment AB is 400%, 1 in is the length of a line segment that is 100%.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

from the given diagram, we get,

the line AB = 4 in.

and,  line segment AB is 400%,

now, we have to find the length of a line segment that is 100%.

so, we get,

4 in = 400%

so, 100% = 4/ 400 * 100

               = 1 in.

Hence, If line segment AB is 400%, 1 in is the length of a line segment that is 100%.
