Step-by-step explanation:
can you find the probability to each of these answers...
Problem 1
Answer: 7/10-----------------------
Explanation:
The formula we'll use is
P(A or B) = P(A) + P(B)
which only works if A and B are mutually exclusive events.
P(A or B) = P(A) + P(B)
P(A or B) = 7/20 + 7/20
P(A or B) = (7+7)/20
P(A or B) = 14/20
P(A or B) = (7*2)/(10*2)
P(A or B) = 7/10
=========================================================
Problem 2
Answer: 3/4-----------------------
Explanation:
We'll use the same formula as the previous problem.
P(A or B) = P(A) + P(B)
P(A or B) = 3/10 + 9/20
P(A or B) = 6/20 + 9/20
P(A or B) = (6+9)/20
P(A or B) = 15/20
P(A or B) = (3*5)/(4*5)
P(A or B) = 3/4
=========================================================
Problem 3
Answer: 3/5-----------------------
Explanation:
We'll use the same formula as the previous problem.
P(A or B) = P(A) + P(B)
P(A or B) = 7/20 + 1/4
P(A or B) = 7/20 + 5/20
P(A or B) = (7+5)/20
P(A or B) = 12/20
P(A or B) = (4*3)/(4*5)
P(A or B) = 3/5
=========================================================
Problem 4
Answer: 0-----------------------
Explanation:
This time we're asked to find P(A and B), but since the two events are mutually exclusive, this means the probability of both occurring is 0.
Mutually exclusive events cannot happen simultaneously.
An example would be flipping heads and tails at the same time on the same coin.
The info about P(A) and P(B) is not relevant.
Let's say you are in Monument Valley and decided to measure the height of a rock formation using the method
you learned from the workbook. The distance from your eyes to your finger is 23 inches. When you look

through your fingers at the rock, the gap between your fingers is of an inch. You know that you are about 6
miles from the rock. According to this information, approximately how tall is that rock formation? Find your
answer in miles (round your answer to the nearest hundredth), then convert it to feet (round it to the nearest
tenth).
miles
feet
Get Help:
Answer:
The answer is "0.163 miles and 860.64 feet"
Step-by-step explanation:
Length between all the finger and the eyes = 23 inches
Length between fingers = 3/4 inches = 0.75 inches
Length between all the person as well as the rock = 5 miles
Length of the shape of rocks =?
The height of an object can be found, as we can see from the above form, using the distance between both the fingertips, its length between all the eyes and thus the fingertips, or the length between the person is calculated by the given formula:
[tex]\frac{\text{Length between fingers}}{\text{Length between fingers and eyes}}= \frac{\text{Rock height}} {\text{Length between the person and the rock}}[/tex]
calculating the height of rock:
[tex]\to \frac{0.75\ inches} {23} \times 5 \\\\\to \frac{3.75\ inches} {23} \\\\\to 0.163 \ miles[/tex]
[tex]\therefore 1 \ mile \ = 5280\ feet[/tex]
[tex]\to 0.163 \times 5280\\\\\to 860.64 \ feet[/tex]

When performing a transformation on a set of data, how do you determine if the transformation is successful?
Answer:
If R² for the transformation is greater than R² for the original regression, the transformation is successful
Step-by-step explanation:
We will follow the process below when conducting a successful transformation on a set of data.
First of all, we will transform either the independent variable or the dependent variable, or even transform both. Secondly, we will conduct a regression analysis by making use of the transformed variables.
Thirdly, we will now compute the coefficient of determination (R2), which will be based on the transformed variables.
Lastly, If the transformed coefficient of determination(R²) is greater than the raw-score (R²) which is the original regression, then we can say that the transformation was successful.
solve for w: k = 3pw

Step-by-step explanation:
k = 3pw
Step 1: switch sides.
3pw = k
Step 2: Since you want w alone, and w is being multiplied by 3p, divide both sides by 3p.

A bakery charges $15 for a box of 12 muffins. At this rate, how much would the bakery charge for a box of 20 muffins?
Answer: $25
Step-by-step explanation:
From the question, we are informed that a bakery charges $15 for a box of 12 muffins. Therefore, a box of 1 muffins will be:
= $15/12
= $1.25 per box of muffins
Therefore, box of 20 muffins will be:
= Price of one box of muffins × 20
= $1.25 × 20
= $25
The perimeter of a rectangle is 50 inches. The length of a rectangle is 10 inches. Which method can be used to find w, the width of the rectangle
Answer:
50=2(10)+2(w)
Step-by-step explanation:
The perimeter is all of the sides added together, so it is L+L+W+W
We know the length is 10, so we substitute 10 for L to get 10+10+W+W
2 tens is 2 times 10 & 2 Ws is 2 times W
50=2(10)+2(w)
In this case, w is 15
Hope this helps :-)

Step-by-step explanation:
point W is on line segment VX. given VW=3 and VX=14, determine the length WX
Answer:11
Step-by-step explanation:14-3=11
By Applying the segment addition postulate, the numerical length of WX is 11.
How to Apply the Segment Addition Postulate?According to the segment addition postulate, point W, point V, and point X are collinear, therefore the following equation is true;
VW + WX = VX.
We are given the following:
VX = 14
VW = 3
We need to find the length WX
Substitute the values into VW + WX = VX
3 + WX = 14
Subtract 3 from both sides
3 + WX - 3 = 14 -3
WX = 11
Therefore, the measure of length of WX is 11.

Someones pls take this seriously and answer at least 4/5 or 5/5 of these questions
Answer:
1. 2w+2*(5w) less than or equal to 96
Step-by-step explan2ation:
The width here is in fact 8, so it is possible to get 96, but it has to be either 96 or lower, so in theory 3 is the only one with the correct symbols. Also, 2w represents the fact that the width, w, is multiplied by 2 since its perimeter. 5x represents length, so length also needs to be multiplied twice. Sorry I don't have time to answer the rest

Answer:
<1= 135 degrees
<4= 135 degrees
<6= 45 degrees
Step-by-step explanation:
This is because angle two and 6 are corresponding angles. you would then subtract 180 from 45 because angle 6 and 4 are consecutive angles. This would give you 135 degrees. Then angle 1 and angle 4 are verticla agles, making them equal to each other.

Maggie runs 1/4 of a mile in 1.3 minutes. Olivia runs 2/3 of a mile in 2.9 minutes. Who runs faster? How much faster per hour does the person run?
Answer:
Olivia-2.25
Step-by-step explanation:
Olivia runs faster than Maggie.
Olivia runs 2.22 miles/hour faster than Maggie.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
To compare the speeds of Maggie and Olivia, we can calculate their respective rates using the formula:
rate = distance/time
For Maggie:
distance = 1/4 mile
time = 1.3 minutes
rate = (1/4) / 1.3 = 0.1923 miles/minute
For Olivia:
distance = 2/3 mile
time = 2.9 minutes
rate = (2/3) / 2.9 = 0.2293 miles/minute
Therefore, Olivia runs faster than Maggie.
To find out how much faster Olivia runs per hour, we can convert her rate to miles per hour:
0.2293 miles/minute x 60 minutes/hour x 60 seconds/minute
= 13.758 miles/hour
Similarly, we can convert Maggie's rate to miles per hour:
0.1923 miles/minute x 60 minutes/hour x 60 seconds/minute
= 11.538 miles/hour
The difference in their speeds is:
13.758 - 11.538
= 2.22 miles/hour
So,
Olivia runs 2.22 miles/hour faster than Maggie.
Thus,
Olivia runs faster than Maggie.
Olivia runs 2.22 miles/hour faster than Maggie.
