Boys = 84 * 2 = 168
Total = 252
Answer:
Step-by-step explanation:
no of girls in grade 3 = 84
by the question no of boys are twice the number of girls so
no of boys = 2 * 84 = 168

A.find the price elasticity of demand at the equilibrium points? quantity demand=72-8p and quantity supply=-24 +24p. B.substitutes the equation.
Answers
Answer:
p = 3
Step-by-step explanation:
The price elasticity of demand at the equilibrium points occurs when quantity demand equals quantity supply.
So,
72-8p= -24 +24p
Taking like terms together,
72+24 = 24p+8p
96 = 32p
p = 3
Hence, the price elasticity of demand is at p = 3.

Answers
Required table is attached below :
Answer:
0.56
Step-by-step explanation:
Since they both have :
SAT score is the same ; quality of letter is the same ;
High school GPA is 1.5 points higher ;
Therefore, to determine how much Mary's GPA will be higher than Karen's :
Multiply the number of points by the Coefficient of high school GPA Given in the regression table attached below :
High school GPA Coefficient = 0.37635
Number of points = 1.5
= 1.5 * 0.37635
= 0.564525

Which statement is true about mixing red and yellow paint?
A. using 1 can of red paint and 2 cans of yellow paint would make the same shade of
orange as Rico's mix.
B. Using 6 cans of red paint and 9 cans of yellow paint would make a shade of orange
more red than Rico's mix.
C. Using 4 cans of red paint and 5 cans of yellow paint would make a shade of orange
more yellow than Rico's mix.
D. Using 6 cans of red paint and 8 cans of yellow paint would make a shade or orange
more red than Rico's mix.
Answers
Answer:
D would be the correct answer
Step-by-step explanation:
Rico's orange is 2/3
A's orange is 1/2, which is not the same color.
B's orange is 6/9, which simplifies to 2/3. This would be the same as Rico's, not a shade redder.
C's orange is 4/5. When comparing them equally, C's orange is 12/15, and Rico's is 10/15. C's orange would be redder than Rico's, not yellower.
D is correct because when comparing the two, 6/9, Rico's orange, has more yellow paint than 6/8. Therefore D's orange would have more red than Rico's orange.

What is the equation of the line in slope-intercept form?
Answers
Answer:
y = -3x + 4
Step-by-step explanation:
y = mx + b
y = y coordinate
m = slope (rise/run, up/over, change in y/change in x)
x = x coordinate
b = y intercept (where the line crosses the y-axis.
1. Write the equation y = mx + b
2. Substitute the numbers in the proper place. y = 3/1 x + 4
3. Check for the type of slope- (positive or negative) y = -3x + 4

Help plz, Im confused with this question
Answers
Answer:
B
Step-by-step explanation:
You are the coach of a basketball team that is currently looking for new players. One of the criteria for selection as a player is that the person must be above a particular height. Ideally, you want your next player to be as tall as possible. However, you do not want to rule out any potential players by making the cut-off height too strict. You decide that accepting players within the top 2.5% height bracket will be reasonable for your team. Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in. Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team. you may find this standard normal table useful. Give your answer in inches to the nearest inch.
C= _____ in
Answers
Answer:
C = 75 in
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.
Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in.
This means that [tex]\mu = 69, \sigma = 2.9[/tex]
Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team.
This is the 100 - 2.5 = 97.5th percentile, which is X when Z has a pvalue of 0.975, so X when Z = 1.96.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.96 = \frac{X - 69}{2.9}[/tex]
[tex]X - 69 = 1.96*2.9[/tex]
[tex]X = 74.7[/tex]
Rounded to the nearest inch,
C = 75 in
