There are 27 bricks in the 12th row. Hope this helps ! :)
Answer:
24 bricks
Step-by-step explanation:
The equation of the bricks per row can be:
b = 60 - 3r
where r = row and b = bricks.
if r = 12:
[tex]b = 60 - 3 * 12\\b = 60 - 36\\b = 24[/tex]
Stella, Roberto, and Candace are
putting together small model kits.
Stella can put a kit together a kit in

How long it will take Candace to put
a kit together if she works alone?
Rico mixed red and yellow paint to create an orange paint color. In Rico's mix he used 2 cans of red
paint and 3 cans of yellow paint.
red
red
yellow yellow Yellow
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.
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.
Hope this helps :)
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
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

if mary smith and karen white have identical sat scores and quality of letter, but mary smiths high school gpa is 1.5 point higher than karen, how much higher will marys college gpa be than karens
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
= 0.56

thank you :)
Answer:
35 degrees
Step-by-step explanation:
180-150=30
115+30=145
180-145=35
35
Answer:
360 degrees - 150degrees =110 degrees
add 110 and 115 degrees to get 225 degrees
next subtract 360 - 225= 135 degrees
so x equals 135

At a height of about 212 meters, One Shell Square is the tallest building in New Orleans. Marlie is creating a scale model of this building, using the scale factor 1:250.
To the nearest tenth of a meter, what will be the height of the scale model?
Enter your answer as a decimal in the box.
given 90 points for answering, thank you!
Answer:
0.8 meters
Step-by-step explanation:
The scale factor is 1:250 (can be rewritten as 1/250 or 1 to 250).
1/250 × 212 = 0.848 Meters
Round to the nearest tenth, the scale model will be 0.8 meters.
OR: SET UP A PROPORTION:
[tex] \frac{250}{1} \times \frac{212}{x} [/tex]
cross-multiply
[tex]250x = 212[/tex]
[tex]x = 0.848[/tex]

What is the equation of the line in slope-intercept form?
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
(Downhill slopes are always negative.)

A company produces only one type of light bulbs. The light bulbs are being manufactured two factories: Factory A and Factory B. Factory A produces 10, 000 bulbs every year, while Factory B produces 2, 000. Also 2% of bulbs from Factory A are defective while 1% of bulbs from Factory B are. After production all bulbs are brought to the same facility and shipped to retail stores.
Required:
a. What is the probability that a bulb bought from a store is defective?
b. Given that the bulb is defective, what is the probability that it was produced by Factory A?
c. Given that the bulb is functional, what is the probability that it was produced by Factory A?
Answer:
Follows are the solution to the given points:
Step-by-step explanation:
Given values:
[tex]P(\frac{D}{A})=0.02 \\\\P(\frac{D}{B})=0.01\\\\P(A)=\frac{10,000}{10,000+2000} =\frac{10}{12} =\frac{5}{6} \\\\P(B)=\frac{1}{6}\\\\[/tex]
For point a:
[tex]P(D) =p(D\cap A) +P(D \cap B)\\\\[/tex]
[tex]=P(\frac{D}{A}) \times P(A) + P(\frac{D}{B}) \times P(B)\\\\=0.02 \times \frac{5}{6} + 0.01 \times \frac{1}{6}\\\\=\frac{0.1}{6} + \frac{0.01}{6}\\\\=\frac{0.1+0.01}{6} \\\\=\frac{0.11}{6} \\\\=\frac{11}{600} \\\\=0.0183[/tex]
For point b:
[tex]P(\frac{A}{D})= \frac{P(\frac{D}{A}) \times P(A)}{P(D)}\\\\[/tex]
[tex]= \frac{0.02 \times \frac{5}{6}}{\frac{11}{600}}\\\\= \frac{0.02 \times \frac{5}{6}}{0.0183333333}\\\\= \frac{0.02 \times 0.833333333}{0.0183333333}\\\\= \frac{0.0166666667}{0.018}\\\\=0.9090 \approx 0.0991[/tex]
For point c:
[tex]P(\frac{A}{D^C})=\frac{P(\frac{D^c}{A}) \times P(A)}{P(D^c)}\\\\[/tex]
[tex]= \frac{1-0.02 \times \frac{5}{6}}{1- \frac{11}{600}}\\\\= \frac{0.98 \times \frac{5}{6}}{0.98}\\\\=\frac{5}{6}\\\\=0.833[/tex]
