A police car leaves a crime scene heading east directly towards the hospital at 72 kilometres per hour. An ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometres per hour. How long will it take for the ambulance to pass the police car?
Answer:
I'm not sure what the answer is but I will tell you when I get it
The time taken by the ambulance to pass the police car is 2 hours and this can be determined by using the formula of speed.
Given :
A police car leaves a crime scene heading east directly towards the hospital at 72 kilometers per hour. An ambulance leaves a quarter of an hour later and also heads directly east towards the hospital at 81 kilometers per hour.The following steps can be used in order to determine the time taken by the ambulance to pass the police car:
Step 1 - The distance travel by the car is calculated as:
[tex]d =72\times 0.25 = 18[/tex]
Step 2 - Now, the difference in speed is calculated as:
[tex]\rm \Delta s =81-72 = 9[/tex]
Step 3 - Now, the time taken by the ambulance to pass the police car is calculated as:
[tex]\rm t = \dfrac{d}{\Delta s}[/tex]
[tex]\rm t = \dfrac{18}{9}[/tex]
t = 2 hours

Answer:
1/5 = 3/15
2/3 = 10/15
When all Added up
= 13/15
Step-by-step explanation:
So our LCD here is 15.
So in order to go from 5 to 15, we multiply by 3, and In order to go from 3 to 15, we multiply by 5. What we do to the denominator we also do to the numerator.
So,
[tex]\frac{1}{5} x \frac{3}{3} = \frac{3}{15}[/tex]
And,
[tex]\frac{2}{3} x \frac{5}{5} = \frac{10}{15}[/tex]
So there you go, multiply for what you need to get to the LCD, and what is done to the numerator is also done to the denominator. Enjoy

Answer:
Step-by-step explanation:
Students use algebra to solve equations (of the form px + q = r and p(x + q) = r where p, q, and r are specific rational numbers); using techniques of making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse) to solve for the variable.
Students identify and compare the sequence of operations used to find the solution to an equation algebraically, with the sequence of operations used to solve the equation with tape diagrams. They recognize the steps as being the same.
Students solve equations for the value of the variable using inverse operations; by making zero (adding the additive inverse) and making one (multiplying by the multiplicative inverse).

A school principal has to choose randomly among the six best students in each grade to be the school captain every month. For that purpose, she assigned each student a number. Then she rolled two dice numbered from 1 to 6 three times and selected the student whose number was repeated most often.
Which of the following best describes the method used by the principal?
It's an unfair method because each student will not post the same outcomes.
It's a fair method because each result is an equally likely possible outcome.
It's a fair method because it's a limited number of students.
It's an unfair method because two or more students could get the same results.
Answer: It's an unfair method because two or more students could get the same results./ D
Step-by-step explanation: hope this helps
Answer:
B. It's a fair method because each result is an equally likely possible outcome.
Step-by-step-explanation :
According to the question , there are a total of 6 students to be selected by the principal.
So, the principal chose to roll two dice numbered 1, 2, 3, 4, 5, 6 for the selected students and choose the one whose number is most repeated.
Since we have sis sides on a dice , 2 dice [tex]= 6\times6=36[/tex]
The probability that a student will choose one number :[tex]\frac{1}{36}[/tex]
Thus, the selection of each student is given by the number
[tex]\frac{1}{36}[/tex]
So,each result is an equally likely possible outcome.
So, the principal choose a fair method.

find 3 solutions to the equation y = 1/2x - 1
The 3 solutions to the equation are (0,-1), (2, 0) and (4, 1)
What are linear equations?Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
How to find 3 solutions to the equation?The equation is given as
y = 1/2x - 1
Next, we set x = 0, 2 and 4
So, we have
When x = 0
y = 1/2 x 0 - 1 = -1
When x = 2
y = 1/2 x 2 - 1 = 0
When x = 4
y = 1/2 x 4 - 1 = 1
Hence, the 3 solutions to the equation are (0,-1), (2, 0) and (4, 1)

At the 0.01 level of significance, is there sufficient evidence to conclude that the proportions differ from those reported in the survey?
Answer:
The proportions differ from those reported in the survey.
Step-by-step explanation:
The Chi-square goodness of fit test would be used to determine whether the proportions differ from those reported in the survey.
The hypothesis for the test can be defined as follows:
H₀: The proportions does not differ from those reported in the survey.
Hₐ: The proportions differ from those reported in the survey.
Assume that the significance level of the test is, α = 0.01.
The Chi-square test statistic is given by:
[tex]\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}[/tex]
Consider the Excel sheet provided.
The Chi-square test statistic value is 191.32.
The p-value of the test is:
[tex]p-value=P(\chi^{2}_{(n-1)}>191.32)\\\\=\text{CHISQ.DIST.RT}(191.32,2)\\\\=0.0000[/tex]
The p-value of the test is very small. The null hypothesis will be rejected at 1% level of significance.
Thus, concluding that the proportions differ from those reported in the survey.
