Segment JL has endpoints J(-3, -4) and L(7, 6). What are the coordinate of point K, so that point K is on line segment JL and JK = 3/5 JL. Explain.
Answer:
K(3,2).
Step-by-step explanation:
We want to find a point K(x,y).
JK = 3/5 JL.
This means that:
[tex]K - J = \frac{3(L - J)}{5}[/tex]
We use this to find both the x-coordinate and the y-coordinate of K.
x-coordinate:
x-coordinate of J: -3
x-coordinate of L: 7
[tex]K - J = \frac{3(L - J)}{5}[/tex]
[tex]x - (-3) = \frac{3(7 - (-3))}{5}[/tex]
[tex]x + 3 = 6[/tex]
[tex]x = 3[/tex]
y-coordinate:
y-coordinate of J: -4
y-coordinate of L: 6
[tex]K - J = \frac{3(L - J)}{5}[/tex]
[tex]y - (-4) = \frac{3(6 - (-4))}{5}[/tex]
[tex]y + 4 = 6[/tex]
[tex]y = 2[/tex]
The point is K(3,2).
The credit scores of 35-year-olds applying for a mortgage at Ulysses Mortgage Associates are normally distributed with a mean of 600 and a standard deviation of 125. (a) Find the credit score that defines the upper 20 percent. (Use Excel or Appendix C to calculate the z-value. Round your final answer to 2 decimal places.) Credit score (b) Eighty-five percent of the customers will have a credit score higher than what value
Answer:
a) The credit score that defines the upper 20% is 705.
b) Eighty-five percent of the customers will have a credit score higher than 470.38.
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.
Mean of 600 and a standard deviation of 125.
This means that [tex]\mu = 600, \sigma = 125[/tex]
(a) Find the credit score that defines the upper 20 percent.
This is the 100 - 20 = 80th percetile, which is X when Z has a pvalue of 0.8. So X when Z = 0.84.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.84 = \frac{X - 600}{125}[/tex]
[tex]X - 600 = 0.84*125[/tex]
[tex]X = 705[/tex]
The credit score that defines the upper 20% is 705.
(b) Eighty-five percent of the customers will have a credit score higher than what value?
This is the 100 - 85 = 15th percentile, which is X when Z has a pvalue of 0.15. So X when Z = -1.037.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1.037 = \frac{X - 600}{125}[/tex]
[tex]X - 600 = -1.037*125[/tex]
[tex]X = 470.38[/tex]
Eighty-five percent of the customers will have a credit score higher than 470.38.
The rectangular pyramid below has a height of 6 inches what is the volume of the pyramid? A. 18 cubic inches
B. 40 cubic inches
C. 120 cubic inches
D. 360 cubic inches
The Volume of rectangular Pyramid whose height inches is 40 cubic inches.
What is the Volume of rectangular pyramid?
The volume of the rectangular pyramid is defined as the capacity of the rectangular pyramid. In geometry, a rectangular pyramid is a three-dimensional geometric shape that has a rectangular base and four triangular faces that are joined at a vertex.
Here, height of pyramid = 6 inches
base area = 4 X 5 = 20 sq. inches
Volume of rectangular pyramid = 1/3 × Base Area × height
= 1/3 X 20 X 6
= 120 / 3
= 40 cu. inches
Thus, the Volume of rectangular Pyramid whose height inches is 40 cubic inches.

Step-by-step explanation:
Find the volume of a pyramid with a square base, where the area of the base is
8.3 m² and the height of the pyramid iş 9.8 m. Round your answer to the nearest
tenth of a cubic meter.
Answer: 27.1 cubic meters
Step-by-step explanation: The area for finding the volume of a pyramid is V=1/3 Bh, where B= base, and h=height. To substitute in the numbers from the problem, you get V=1/3 times 8.3 times 9.8. 9.8 times 8.3 is 81.34. 81.34 times 1/3 rounds to 27.1.

3) Suppose you deposit $10,000 in a savings account that pays interest at an annual rate of 5%
compounded quarterly. How many years will it take for the balance in your savings account to reach
$12,000?
9514 1404 393
Answer:
3.67 years
Step-by-step explanation:
The amount is found using the compound interest formula.
A = P(1 +r/n)^(nt)
for principal P invested at annual rate r compounded n times per year for t years.
We can solve this for t:
A/P = (1 +r/n)^(nt) . . . . divide by P
log(A/P) = (nt)log(1 +r/n) . . . . take the logarithm
t = log(A/P)/(n·log(1 +r/n)) . . . . divide by the coefficient of t
Filling in the given values, we find ...
t = log(12000/10000)/(4·log(1 +0.05/4)) ≈ 3.6692
It will take about 3.67 years for the balance to reach $12,000.
Answer:
the answer is 3.67 years

sarah walks 1/4 mile every 1/2 hour
Answer:
To find ratio mph (miles PER hour), we can write the information given as a fraction. (The miles will go on top and the number of hours will go on the bottom).
1/2=.5 miles
1/4-.25 miles
So we have .5miles/.25 hours
From here, we can do 2 things: divide to get 2miles/hour or you can see that you can reduce the fraction (.5/2=.25 and .25/.25=1). So again we get 2/1 miles per hour OR 2 mph
Hope that helps,

Which statement is not true about the pattern shown?
2/3 4/6 8/12 16/24
A-Each fraction is greater than the previous fraction.
B-Each fraction is equal to the previous fraction in the pattern multiplied by
C-Each fraction is equivalent to 2/3
D-The next fraction in the pattern is 32/48
Answer:
The answer is A-Each fraction is greater than the previous fraction.
Step-by-step explanation:
To prove that A is wrong, first simply all fractions.
2/3 is already simplified.
4/6 can reduce to 2/3, which already proves that A is wrong.
So, because 2/3 and 4/6 are equal fractions, and A says that each fraction is greater than the previous one, A is wrong.
When a new drug is created, the pharmaceutical company must subject it to testing before receiving the necessary permission from the Food and Drug Administration (FDA) to market the drug. Suppose the null hypothesis is "the drug is unsafe." What is the Type II Error? ( Select the one, correct letter option below) :
Answer:
Not to conclude that the drug is safe, when, in fact, it is safe.
Step-by-step explanation:
A type ii error is an error that occurs in a hypothesis testing when a person goes ahead to accept a null hypothesis when it is actually false and should be rejected.
To continue, here are the hypothesis:
H0: the drug is unsafe
H1: drug is safe.
A type ii error was committed here because H0, which is the null was accepted and it was concluded that the drug was unsafe, When in fact it should have been rejected. The conclusion should have been that the drug was safe.

Element X is a radioactive isotope such that its mass decreases by 59% every day. If an experiment starts out with 390 grams of Element X, write a function to represent the mass of the sample after tt days, where the hourly rate of change can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage rate of change per hour, to the nearest hundredth of a percent.
The function representing the mass of Element X after t days is [tex]{\text} M(t) = 390 * (0.41)^t[/tex], and the percentage rate of change per hour is 2.46%.
Given:
Initial mass = 390 grams
Rate of decay = 59% = 0.59
The general form of an exponential decay function is:
[tex]{\text}y = a (1 - r)^t[/tex]
So, the function to represent the mass of the sample after t days would be:
[tex]{\text} (t) = 390 * (1 - 0.59)^t[/tex]
Simplifying this equation gives
[tex]M(t) = 390 * (0.41)^t[/tex]
Now, the hourly rate of change is
Hourly rate of change = 0.59 / 24
= 0.024583
= 2.46% per hour.
Therefore, the function is [tex]{\text} M(t) = 390 * (0.41)^t[/tex]and the rate of change is 2.46%.
