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%

Point X is on a number line halfway between –5 and 11. Point Y
represents an integer that has the same absolute value as point X.
What integers could be represented by point Y?
please help asap
Answer:
[tex]y = 3[/tex] or [tex]y =-3[/tex]
Step-by-step explanation:
Given
x = midpoint of -5 and 11
y = absolute value of x
Required
Determine the value of y
First, calculate x.
[tex]x = \frac{1}{2}(-5 + 11)[/tex]
[tex]x = \frac{1}{2}(6)[/tex]
[tex]x = 3[/tex]
y can then be represented as:
[tex]|y| = x[/tex]
[tex]|y| = 3[/tex]
Split:
[tex]y = 3[/tex] or [tex]-y = 3[/tex]
[tex]y = 3[/tex] or [tex]y =-3[/tex]

Explain in words please.
Answer:
I don't know what you mean by "explain in words", but I'm assuming you were referring to point b.
Step-by-step explanation:
You have to see that the rate of change, the "speed" at which her elevation decreases is 0.25 feet/s, such that in 8 seconds she went down by 2 feet.
Thus, until 50, you just gotta do the calculation for that speed. You notice that she needs to go 30 feet, at a speed of 0.25 feet per second, or 1 foot every 4 seconds.

is it true or false that all whole numbers are natural numbers
Answer:it can very
Step-by-step explanation:
It depends on which definition of 'whole numbers' you use.
Some definitions say the whole numbers are the set of positive integers including zero; or the set of all non-negative integers. In this case, the answer would be 'false', since the set of integers includes negatives.
However, if you are using a definition of whole numbers which includes positive integers, including zero, and their negatives, the answer would be 'true'. Figure out how the term 'whole numbers' is being defined, then you can get your answer.
Answer:
every natural number is a whole number, but, every whole number is not a natural number.

There were some apples in a box. 12% of the apples were rotten.
There were 36 rotten apples in the box. How many apples were there
in the box?
Answer:
300
it is given that 12% were rotten
12% = 36
then let total no of apple be X
then , x*12/100 = 36
x= 36*100/12
x = 300
hence total apple were. = 300

5. X is a normally distributed random variable with a mean of 8 and a standard deviation of 4. This can be written as N(8,4). The probability that X is between 1.48 and 15.56 is _____________. Write out the probability notation for this question.
Answer:
The probability that X is between 1.48 and 15.56 is [tex]P(1.48 \leq X \leq 15.56) = 0.919[/tex]
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
X is a normally distributed random variable with a mean of 8 and a standard deviation of 4.
This means that [tex]\mu = 8, \sigma = 4[/tex]
The probability that X is between 1.48 and 15.56
This is the pvalue of Z when X = 15.56 subtracted by the pvalue of Z when X = 1.48. So
X = 15.56
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{15.56 - 8}{4}[/tex]
[tex]Z = 1.89[/tex]
[tex]Z = 1.89[/tex] has a pvalue of 0.9706
X = 1.48
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{1.48 - 8}{4}[/tex]
[tex]Z = -1.63[/tex]
[tex]Z = -1.63[/tex] has a pvalue of 0.0516
0.9706 - 0.0516 = 0.919
Write out the probability notation for this question.
[tex]P(1.48 \leq X \leq 15.56) = 0.919[/tex]
The probability that X is between 1.48 and 15.56 is [tex]P(1.48 \leq X \leq 15.56) = 0.919[/tex]
What number must you add to complete the square?
x2 + 16x = 3
O A. 16
B. 36
O C. 64
O D. 72
What number must you add to x² + 16x = 3 to complete the square 64: Option C
What is a perfect square?You should be aware that a perfect square is a term that has two common factors
The given equation is x² + 16x = 3
To make the equation a perfect square, Add the square of half of the coefficient of s to both sides
This is to say that (16/2)² = 8² = 64
The equation becomes x²+16x+64 = 3+64
Then you can factorize the equation and simplify the right hand side
