In Joel's town, about 33 out of 100 cats are black. If Joel walks by 21 cats in 1 week, predict how many of those cats are black?
Answers
Answer:
7 cats are black
Step-by-step explanation:
Since 33 out of 100 cats are black then that means that 33% of the cats are black.
Since he walked by 21 cats 33% of them are most likely black.
So you do .33 x 21= 6.93 which can be rounded up to 7 cats

Find the center and radius of a circle that has a diameter with the given endpoints.
(7, -5) and (-1, 10)
Answers
Answer:
center: (3, 2.5)radius: 8.5 unitsStep-by-step explanation:
The center of a circle is the midpoint of any diameter. The midpoint of a segment has coordinates that are the average of the coordinates of the segment end points.
The length of the radius is the distance from the center to an end point of a diameter. Alternatively, it is half the length of the diameter.
__
Center = (A +B)/2 = ((7, -5) +(-1, 10))/2 = (6, 5)/2 = (3, 2.5)
Radius = 1/2|AB| = 1/2√((7 -(-1))² +(-5 -10)²) = 1/2√(64 +225) = 1/2√289
= 17/2 = 8.5
The center of the circle is (3, 2.5), and the radius is 8.5 units.

Use this information to answer questions 3, 2, and 5. Other than (1, 0), (0, 1), (-1, 0), and (0, -1), the coordinates used in the previous question involved approximations. The point (0.8, 0.6), however, lies exactly on the unit circle.
What relationships or patterns do you notice in the coordinates?
3. Explain why this must be true.
5. What are the approximate angle measures needed to intersect at (0.8, 0.6) and each of these new points?
4. List all other points on the unit circle that also like exactly at the intersection of two grid lines.
Answers
The pοint (0.8, 0.6) lies οn the unit circle because its distance frοm the οrigin is 1. Tο see why we can use the Pythagοrean theοrem: \(\sqrt{((0.8)^2 + (0.6)^2)} = \sqrt{(0.64 + 0.36)} = \sqrt{(1) = 1.\)
Tο find the angle measure needed tο intersect at (0.8, 0.6), we can use inverse trigοnοmetric functiοns. Since cοsine is the x-cοοrdinate and sine is the y-cοοrdinate, we have cοs(theta) = 0.8 and sin(theta) = 0.6.
Taking the arccοsine οf 0.8 gives an angle οf apprοximately 36.87 degrees, and taking the arcsine οf 0.6 gives an angle οf apprοximately 48.19 degrees. Sο the apprοximate angle measures needed tο intersect at (0.8, 0.6), and each οf these new pοints are 36.87 degrees and 48.19 degrees.
The οther pοints οn the unit circle that lie exactly at the intersectiοn οf twο grid lines are (0, 1), (1, 0), (-1, 0), and (0, -1). These are the pοints where the angle measure is a multiple οf 90 degrees (0, 90, 180, and 270 degrees, respectively).

Convert 12 kg to lbs
Answers
12 kg is equal to 26.45 pounds.
To convert kilograms (kg) to pounds (lbs), you can use the conversion factor 1 kg = 2.205 lbs. To convert 12 kg to lbs, you would multiply 12 by 2.205, which gives you 26.45 pounds.
It's important to note that the pound is a unit of weight in the Imperial system of measurement, while the kilogram is a unit of weight in the Metric system of measurement.
These two systems are not directly comparable, so it's essential to use a conversion factor when switching between them. In addition, it's good to know that the pound is commonly used in the United States, while the kilogram is more commonly used in other countries around the world.

A nutrition researcher wants to determine the mean fat content of hen's eggs. She collects a sample of 40 eggs. She calculates a mean fat content of 23 grams with a sample standard deviation of 8 grams. From these statistics, she calculates a 90% confidence interval of 20.9 grams to 25.1 grams. What can the researcher do to decrease the width of the confidence interval?
a. increase the confidence level
b. decrease the confidence level
c. decrease the sample size
d. none of the above
Answers
To decrease the width of the confidence interval, the researcher can take the following steps:
1. Decrease the confidence level: The confidence interval width is inversely proportional to the confidence level. By decreasing the confidence level, the researcher can have a narrower interval. However, it is important to note that decreasing the confidence level also increases the chance of the interval not capturing the true population mean.
2. Increase the sample size: The sample size affects the precision of the estimate. Increasing the sample size reduces the standard error, which leads to a narrower confidence interval. This is because a larger sample provides more information about the population.
Therefore, the researcher can decrease the width of the confidence interval by either decreasing the confidence level or increasing the sample size. Both approaches will result in a narrower interval, providing a more precise estimate of the mean fat content of hen's eggs.

Step-by-step explanation:
Given that :
Female in fatal accident P(F) = 0.2805
Driver is 24 years or less P(A) = 0.1759
Driver is female and 24 years or less P(FnA) = 0.0424
A.) Find the probability of FUA.
P(FUA) = P(F) + P(A) - P(FnA)
= 0.2805 + 0.1759 - 0.0424
= 0.4140
(b) Find the probability of F'UA.
P(F'UA) = 1 - P(F) + P(FnA)
= 1 - 0.2805 + 0.0424
= 0.7619
C.) P(FnA') = 1 - P(F'UA)
= 1 - 0.7619

P(F'nA') = (FnA)' = 1 - (FnA)

The percentage of students at the college have a gpa below 2.4 is 15.87%.
Given,
The gpa's are normally distributed with given mean and SD.
mean \(\bar{x}\)= 2.8
SD σ=0.4
raw score=2.4
The z score can be calculated by using the formula
z=\(\frac{x-\bar{x}}{\sigma}\)
z=\(\frac{2.4-2.8}{0.4}\)
\(z=\frac{-0.4}{0.4}\)
z=-1
Using the z table we get the value P(z<-1), it is 0.8413, as it is less than we subtract it from 1 and we get 0.1587. As the value we got is negative, we used left tail z table to get the value of the z.
To get the percentage, we have to multiply by 100,

When we calculate probabilities involving one event AND another event occurring, we multiply their probabilities.
According to me , independent is the word which is associated with multiplication when computing probabilities . Because when the events are independent then we multiply the probabilities .
According to the multiplication rule of probability, the probability of occurrence of both the events A and B is equal to the product of the probability of B occurring and the conditional probability that event A occurring given that event B occurs.
The probability of the union of two events is equal to the sum of individual probabilities. The union of two set contains all the elements of previous sets. The union is denoted by ∪. The equation for the students earnings will be expressed as P(A∪B). The occurrence of event A changes the probability of B then the events are dependent. If the probability of two events happening together is zero then the events are mutually exclusive.
