Answer:
D)75miles
Step-by-step explanation:
they were both traveling at 75 miles per hour and Kristin drove one hour more than Todd
D) 75 miles
Step-by-step explanation:
Todd drove 375 miles in 5 hours (75 mph). Kristin drove the same speed (75 mph) in 6 hours.
75 mph x 6 hours = 450 miles
450-375= 75 more miles

Question 10 > Two skiers are 43.5 kilometers apart and head towards each other. They meet in 1.5 hours. If the second skier is 7 kilometers per hour faster the the other, find the speed of each skier? Distance || Rate || Time Slow Skier Fast Skier Total The slow skier travels at kilometers per hour. The fast skier travels at kilometers per hour. Question Help: Message instructor Submit Question
Answer:
The first skier goes at a speed of 11 kilometers per hour, while the second does it at a speed of 18 kilometers per hour.
Step-by-step explanation:
Given that two skiers are 43.5 kilometers apart and head towards each other, and they meet in 1.5 hours, if the second skier is 7 kilometers per hour faster the other, to find the speed of each skier the following calculation must be performed:
43.5 / 1.5 = 29
29 - 7 = 22
2/22 = 11
11 x 1.5 + 18 x 1.5 = X
43.5 = X
Thus, the first skier goes at a speed of 11 kilometers per hour, while the second does it at a speed of 18 kilometers per hour.

Airlines monitor the causes of flights arriving late. A total of 75% of flights are late because of weather, while 35% of flights are late because of ground operations. A full 10% of flights are late because of weather and ground operations. What is the joint probability that a flight arrives late because of weather and ground operations
Answer:
36% is the joint probability that a flight arrives late because of weather and ground operations
Step-by-step explanation:
Given
% of flight late because of weather = 0.75
% of flight late because of ground operation = 0.35
% of flight late because of both weather and ground operation = 0.10
The probability of joint probability that a flight arrives late because of weather and ground operations is equal to
p (A and B) + {P(A) * P(B)}
0.10 + (0.75 * 0.35)
0.36
or 36%
Answer:36%
Step-by-step explanation:0.10 + (0.75 * 0.35)=0.36 then turn it to a percent which is 36%.
Imagine that a researcher correctly computes a correlation coefficient to quantify the relationship between two variables. In the data set that she works with, low scores on Variable X tend to be paired with low scores on Variable Y, and high scores on Variable X tend to be paired with high scores on Variable Y. Based on this data set, what type of correlation coefficient should the researcher expect to find
Answer:
Positive value of correlation Coefficient
Step-by-step explanation:
The correlation Coefficient value, R is a correlation measure which gives information about both the strength of association between two variables and also the type of association between them (negative or positive). R has a standardized value which ranges from - 1 to +1
Negative relationship between variables are depicted with negative (where one variable decreases as the other increases) R value while positive association (increase in one variable means leads to increase in the other variable) are depicted with positive R values.
Therefore, for the relationship described above, the correlation Coefficient will be positive.

Answer:
F'=(1,-5)
Step-by-step explanation:
First off, F is moved 4 units right and 2 units down: add 4 to the x component of the coordinate and take 2 from the y component:
-3+4=1
7-2=5
So our point is (1.5) before it is reflected over the y-axis.
When a point (a,b) is reflected over the y-axis, it's coordinates change to (a,-b). Therefore (1,5) changes to (1,-5)
Which inequality can be used to find the domain of
Answer:
1/2 x -10 ≥ 0
Step-by-step explanation:
We know that a square root must have an answer that is greater that or equal to zero. The result of a square root cannot be negative. What is inside the square root must be greater than or equal to zero. To find the domain we solve that equation to determine the value of x.
1/2 x -10 ≥ 0

Answer:
1: mean equals 17.417, median is 12.75, mode is 8.2, range is 33, the minimum is 8.2 the maximum is 41.2. The IQR is 16.55, the quartiles is q1: 8.95, q2: 12.75, q3 is 25.5, there are no outliers.
2: the best middle is 12.75 because the median is usually the middle number but if you orgainze the numbers there will be two but you will end up getting 12.75 as your median. take the two middle number add together then divide by 2 then that is your answer.

An engineer designed a valve that will regulate water pressure on an automobile engine. The engineer designed the valve such that it would produce a mean pressure of 4.6 pounds/square inch. It is believed that the valve performs above the specifications. The valve was tested on 26 engines and the mean pressure was 4.9 pounds/square inch with a variance of 0.81. A level of significance of 0.05 will be used. Assume the population distribution is approximately normal. Determine the decision rule for rejecting the null hypothesis. Round your answer to three decimal places.
Answer:
Decision Rule; Reject H₀ if t > 1.708
Step-by-step explanation:
Given the data in the question;
sample size n = 26
sample mean x' = 4.9
Variance = 0.81
standard deviation σ = √variance = √0.81 = 0.9
level of significance ∝ = 0.05
Claim;
Null hypothesis H₀ : μ = 4.6
Alternative hypothesis H₁ : μ > 4.6
Test Statistics;
Right tailed test
Now, decision rule for rejecting H₀;
degree of freedom df = n - 1 = 26 - 1 = 25
so, Right tailed test { > in H₁ }
Hence, Critical Value = [tex]t_{\alpha ,df[/tex] = [tex]t_{0.05, 25[/tex] = 1.708
Decision Rule; Reject H₀ if t > 1.708

A traveling circus is moving in a train consisting of 20 cars, which were randomly adjoined to each other. 2 cars are carrying clowns, 2 cars house trapeze artists, 4 are reserved for lions, 4 - for bears, 4 - for elephants, and 4 for tents and provisions. What is the probability that no elephant or bear car precedes the first car with lions
Answer:
the no elephant or bear car precedes the first car with lions is 0.60
Step-by-step explanation:
The computation of the probability is shown below:
= 1 - (no depend or acrobat car precedes)
= 1 - (4 ÷ 20 + 4 ÷ 20)
= 1 - 8 ÷ 20
= 20 - 8 ÷ 20
= 12 ÷ 20
= 0.60
Hence, the no elephant or bear car precedes the first car with lions is 0.60
The same would be considered and relevant too
