Answer: choice A
Step-by-step explanation:
The shaded area represents the complement of B.
Bc or B’ is the complement of B and B’=1-B or B’=S-B
The probability that Events A and B occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B), which in this example would be equal to B.
The probability that Events A or B occur is the probability of the union of A and B. The probability of the union of Events A and B is denoted by P(A ∪ B), which in this example is equal to S.

A car bought for RS 1,000,000 depreciates each year by 5%.what is the insurance premium paid in the first year , second year , and the third year of purchase?
Answers soon!!
Answers
Answer:
1st year = RS 50,0002nd year = RS 47,5003rd year = RS 45,125Step-by-step explanation:
Given the cost of a car to be RS 1,000,000, if the car depreciates yearly by 5%, then the insurance premium paid which is the operating expenses eacg year will be calculated as thus;
In the first year;
insurance premium paid = 5% of RS 1,000,000
= 5/100 * 1,000,000
= RS50,000
cost of the car after the first year of usage = 1,000,000-50,000
= RS 950,000
In the second year;
Insurance premium paid in the second year = 5% of RS 950,000
= 5/100 * 950,000
= 5*9,500
= RS 47,500
cost of the car at the end of second year = 950,000-47,500 = RS 902,500
In the third year;
Insurance premium paid in the third year = 5% of RS 902,500
= 5/100 * 902,500
= 5*9,025
= RS 45,125

Lance needs 50 cups of water for the runners in a race. Convert the volume to gallons.
Answers
Answer:
Lance would need 3.125 gallons of water.
Step-by-step explanation:
Divide the value by 16
After converting the volume into gallons, Lance needs 3.125 gallons of water for the runners in a race.
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Lance needs 50 cups of water for the runners in a race.
We know that;
⇒ 1 gallons = 16 cups
⇒ 1 cups = 1/16 gallons
Here, Lance needs 50 cups of water for the runners in a race.
Hence, We get;
⇒ 50 cups = 50 × 1/16 gallons
= 3.125 gallons

A triangular prism has a triangular base with dimensions of 3" by 4" by 5"
and a volume of 210 in? What is the surface area of the triangular prism?
Answers
Answer:
432in²Step-by-step explanation:
Volume of a triangular based prism = [tex]Base\ area * height[/tex]
Base area = Area of the triangle = 1/2 * base of the triangle * height of the triangle
Since the triangular base has dimensions of 3" by 4" by 5", then it is a right angled triangle with base of 4in and height of 3in
Base Area = 1/2 * 3 * 4
Base Area = 6in²
Substituting the volume and the base area value in the formula to get the height of the prism we have;
210 = 6H
H = 210/6
H = 35in
Surface area of the triangular prism = bh + pH
b= base of the triangle = 4in
h- height of the triangle = 3in
p= perimeter of the triangle = 3+4+5 = 12in
H= height of the prism = 35in
Surface area of the triangular prism = 4(3)+12(35)
Surface area of the triangular prism = 12+420in
Surface area of the triangular prism = 432in²

A can of pumpkin pie mix contains a mean of 30 ounces and a standard deviation of 2 ounces. The contents of the cans are normally distributed.. Supposed four can of pumpkin pie mix are randomly selected What is the probalility that the average content of cans in sample is between 28.0 ounces and 31.5
Answers
Answer:
[tex]P(28<X<31.5)=P(\frac{28-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{31.5-\mu}{\sigma})=P(\frac{28-30}{2}<Z<\frac{31.5-30}{2})=P(-1<z<0.75)[/tex]
We can find this probability with this difference
[tex]P(-1<z<0.75)=P(z<0.75)-P(z<-1)[/tex]
If we use the normal standard distribution or excel we got:
[tex]P(-1<z<0.75)=P(z<0.75)-P(z<-1)=0.773-0.159=0.614[/tex]
Step-by-step explanation:
Let X the random variable that represent the weights for a can of pumpkin pie, and for this case we know the distribution for X is given by:
[tex]X \sim N(30,2)[/tex]
Where [tex]\mu=30[/tex] and [tex]\sigma=2[/tex]
We are interested on this probability
[tex]P(28<X<31.5)[/tex]
We can use the z score formula given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
Using this formula we got:
[tex]P(28<X<31.5)=P(\frac{28-\mu}{\sigma}<\frac{X-\mu}{\sigma}<\frac{31.5-\mu}{\sigma})=P(\frac{28-30}{2}<Z<\frac{31.5-30}{2})=P(-1<z<0.75)[/tex]
We can find this probability with this difference
[tex]P(-1<z<0.75)=P(z<0.75)-P(z<-1)[/tex]
If we use the normal standard distribution or excel we got:
[tex]P(-1<z<0.75)=P(z<0.75)-P(z<-1)=0.773-0.159=0.614[/tex]

Answers
Answer:
C. No, the distribution is not symmetric and the frequencies do not start off low.
Step-by-step explanation:
Hello!
You have the data of daily rainfall for one month (inches)
To arrange a data set in a frequency table you have to determine the number of class intervals you want to make, then you calculate their widths as: "total observations"/"desired number of intervals". Once you have the class width, you can determine the limits of the intervals. For the first interval, you select the minimum value of the sample and add the width to obtain the upper limit. Then you have to use that limit as the lower limit of the next interval and add the width to obtain the next limit. And so on until the last one.
In this example you have a given class width of 0.20 and the lower limit for the first interval is 0.00.
Once you have all intervals determined, you have to arrange the data set from least to greatest and count how many observations correspond to each interval.
The symbol [;) in the intervals indicates that the interval is "closed" on the lower limit and "open" on the upper limit. Meaning, if you have for example the observation "0.20" and the intervals [0.00; 0.20) and [0.20; 0.40), the first interval has a limit equal to 0.20 but is open, meaning that the observation does not belong to it, it belongs to the next interval.
(See table in attachment)
Does the frequency distribution appear to be roughly a normal distribution?
A. No, although the distribution is approximately symmetric, the frequencies do not start low, increase to some maximum frequency, then decrease.
B. No, although the frequencies start low, increase to some maximum, then decrease, the distribution is not symmetric.
C. No, the distribution is not symmetric and the frequencies do not start off low.
D. Yes, all the requirements are met.
As you can see not all defined intervals have at least one observed frequency, most of the observations belong to the first and second one. And there is value, 1.28 inches, that shifts the distribution to the right making it strongly skewed. This distribution is far away from being normally distributed.
Hope it helps!

A box of books weighs 26lb. Convert the weight to kilograms. Round to the nearest tenth.
Answers
Answer:
26 lb is 11.8 kg.
Step-by-step explanation:
A pound (lb) is a unit of mass used in the imperial and US customary systems of measurement.
A kilogram (kg) is the base unit of mass in the International System of Units (SI).
To convert 26 lb to kg.
First, use the conversion factor between pounds and kilograms.
1 kg = 2.2046 lb
Next, write the following equation to find the weight in kg:
weight in kg = weight in lb x (1 kg / 2.2046 lb)
The pounds cancel out, leaving kilograms.
weight in kg = 26 lb x (1 kg / 2.2046 lb)
weight in kg = 11.7935 kg
Rounding to the nearest tenth.
weight in kg = 11.8 kg
Given tan θ = 2 and sin θ < 0. Find cos(θ +pi/4)
Answers
Answer:

Step-by-step explanation:
tan θ > 0 and sin θ < 0, so θ is in quadrant III. That means cos θ < 0.
cos(θ + π/4)
Use angle sum formula.
cos θ cos(π/4) − sin θ sin(π/4)
½√2 cos θ − ½√2 sin θ
Factor.
½√2 cos θ (1 − tan θ)
½√2 cos θ (1 − 2)
-½√2 cos θ
Write in terms of secant.
-½√2 / sec θ
Use Pythagorean identity (remember that cos θ < 0).
-½√2 / -√(1 + tan²θ)
-½√2 / -√(1 + 2²)
½√2 / √5
