Answers
Answer:
x = 7
Step-by-step explanation:
Based on the angle bisector theorem, we would have the following equation:
21/(3x - 12) = 14/6
21/(3x - 12) = 7/3
Cross multiply
(3x - 12)*7 = 3*21
21x - 84 = 63
21x - 84 + 84 = 63 + 84
21x = 147
21x/21 = 147/21
x = 7

Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 573 and a standard deviation of 84. Use the 68-95-99.7 Rule to find the percentage of people taking the test who score between 489 and 573
The percentage of people taking the test who score between 489 and 573 is
Answers
Answer:
The percentage of people taking the test who score between 489 and 573 is 34%.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean of 573, standard deviation of 84
Percentage of people taking the test who score between 489 and 573
The mean is 573.
489 = 573 - 84, which means that 489 is one standard deviation below the mean.
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are below the mean.
So between one standard deviation below the mean and the mean, the percentage is 68/2 = 34%
The percentage of people taking the test who score between 489 and 573 is 34%.
What is the measured of bacteria at t=0?
Answers
Answer:
Number of bacteria when t = 0 is 2,000
Step-by-step explanation:
Given:
Number of bacteria in a culture by equation
Q(t) = 2(729^t)
Value of t = 0
where t is number of hours
Find:
Number of bacteria when t = 0
Computation:
Given equation
Q(t) = 2(729^t)
Put t = 0
Q(0) = 2(729⁰)
We know that;
a⁰ = 1
So,
Q(0) = 2(729⁰)
Q(0) = 2(1)
Q(0) = 2
Number of bacteria when t = 0 is 2,000

Shelly bought a dozen pens for $144.
(a) Find the cost of 15 such pens.
(b) How many pens can be bought
for $84?
Answers
Answer:
A. 180
b. 7
Step-by-step explanation:
Answer:
a. $180
b. $7
Step-by-step explanation:
In order to easily find the cost of x amount of pens, first find the unit price:
The unit price is the price for 1 of somethingTo find how much 1 pen is, divide 144 ÷ 12 (1 dozen = 12)144 ÷ 12 = 121 pen = $12Part A - Find the cost of 15 pens:
Since we've just found the price of 1 pen, multiply the price by 1512 × 15 = $18015 pens cost $180 (outrageous!)Part B - How many pens can be bought for $84?:
Since we know the cost of 1 pen is $12, we can work backwards on this stepTo find the amount of pens that can be bought with $84, divide 84 ÷ 1284 ÷ 12 = 77 pens can be boughtEastside middle school has 1,500 students.

what is the total area of the shape below
Answers
Answer:
480 ft
Step-by-step explanation:
480ft²
explanation:
first of all, find the area of the rectangle as it is the easiest.
So, do A = L x W.
A = 24 x 15
= 360ft²
Then find the area of half of the triangle.
So, do A = 1/2 x b x h
The length of the base of the full triangle (aka top of the rectangle) is 24ft so since we are finding the area of half of the triangle all you have to do it half 24 (12). (also 1/2 is the same as 0.5)
So the equation for that would be
A = 1/2 x b x h
= 1/2 x 12 x 10
= 1/2 x 120
= 60
So now, to find the area of the whole triangle, times 60 by 2 (as both of the halves are the same) which gives you 120.
Finally, to find the area of the WHOLE shape, do 360ft² + 120ft² which gives you 480ft².

plz help i need to know 94=10a-7 and 7k+10=31
Answers
Answer:
a=10.1
k=3
Step-by-step explanation:
Lets solve the first equation first.
94=10a-7
Lets add 7 to both sides.
101=10a
Divide both sides by 10 to isolate a
101/10=a
a=10.1
Lets do the second equation.
7k+10=31
Subtract 10 from both sides
7k=21
Divide 7 by both sides to isolate k
k=3

Answers
Answer:
Option a (the feasible........BLUE) is the correct option.
Step-by-step explanation:
The association with a certain variable and perhaps a lagging representation with its own over time is termed as Serial correlation. OLS could even deliver skewed outcomes and can't thus be utilized attributable to serial correlation. GLS has always been then used that follows BLUE, in other words, GLS even though in this circumstance becomes an appropriate Unbiased Linear Estimator.The other alternatives are not related to the given scenario. So the above is the right option.
