18 girls and 12 boys on a swim team. what is the percentage of boys?​

Answers

Answer:

40%

Step-by-step explanation:

The first step is to add 18 girls + 12 boys, which gives you the total number of people on the swim team, 30.

Next, you divide the 12 boys by the total swim team members, so:

[tex]\frac{12}{30}[/tex] = 0.4

Then, you multiply 0.4 by 100 to get the percentage:

0.4 × 100 = 40

Therefore, the swim team is made up of 40% boys, and 60% girls.

Answer:

40%

Step-by-step explanation:

30 total kids

12/30 as a decimal is 0.4

to make a decimal into a percent you move the decimal point 2 times to the right

that would be 40

then add the percent to make 40%

Melany takes her little sister to the zoo. They go see their favorite animal, the giraffe. At the gift shop, Melany buys a stuffed giraffe for her little sister that has a scale on 4 in : 3 ft. If the real giraffe is 18 feet tall, how tall is the stuffed giraffe, in inches?

Answers

Let us set up a proportion.

4/3 = 18/t

Let t = height of giraffe (in inches)

We also have to change units to make our math work easier.

There are 12 inches in one foot.

So, 3 feet = 36 inches and 18 feet = 216 inches.

Our new proportion set up is:

4/t = 36/216

36t = 4(216)

36t = 864

t = 864/36

t = 24

The toy giraffe is 24 inches tall.

The solution to the equation 3 (4x - 2) - 5x = 6 - 7 (-x -2) does not exist

How to determine the solution to the equation

From the question, we have the following parameters that can be used in our computation:

3 (4x - 2) - 5x = 6 - 7 (-x -2)

Open the brackets

So, we have

12x - 6 - 5x = 6 + 7x + 14

Evaluate the like terms

So, we have the following representation

7x - 6 = 7x + 20

Next, we have

7x - 7x = 20 + 6

So, we have

0 = 26

This is false

Hence, the solution is no solution

Many studies have investigated the question of whether people tend to think of an odd or an even number when they are asked to think of a single-digit number (0 through 9). Combining results from several studies, Kubovy and Psotka (1976) used a sample of 1,770 people, of whom 741 thought of an even number and 1,029 thought of an odd number. Would a one-sided or a two-sided alternative hypothesis be more appropriate in this case

Answers

Answer:

A two-sided alternative hypothesis would be more appropriate in this case

Step-by-step explanation:

A one-sided hypothesis is one that asserts that a given parameter is either smaller than the null hypothesis value or larger than the value presented by the null hypothesis.

However in a two sided hypothesis, the claim is made that a given parameter is not equal to the parameter given in the null hypothesis, such that the parameter can be either larger than than or lesser than the value of the null hypothesis and still satisfy the condition of the hypothesis

Therefore, given for that for there to be a conclusion, the test should be weather the number of people that think of an odd number are equal to the number of people that think of an even number, or weather the number of people that think of an odd number are not equal to the number of people that think of an even number

Therefore, a two-sided hypothesis should be used since the claim (that the numbers are not equal) is not equal to the value of the parameter in the null hypothesis (that the numbers are equal)

Q1: A number minus 4 is greater than 2 times a number

Answers

Answer:

x - 4 > 2x

(see below to solve for x if needed)

Step-by-step explanation:

"Greater than" is key word for the greater than symbol: >.

"A number" can be represented by x.

So "a number minus four" would be x - 4 and "two times a number" would be 2x.

So "A number minus 4 is greater than 2 times a number" is:

x - 4 > 2x

If you were to solve for x, it would be:

x - 4 > 2x

-x         -x

-------------

-4     > x

x < -4
