Answer:
0.1786 = 17.86%
Step-by-step explanation:
120 + 90 = 210/504 journey by car
Relative frequency of 90/ 504
= 90/504 =0.178571429
0.1786 = 17.86%
The requried relative frequency of females who get to school by car in relation to the total students at the school is approximately 0.1786 or 17.86%.
What is the relative frequency?Relative frequency is a measure that indicates the proportion or percentage of times an event occurs in relation to the total number of events. It is calculated by dividing the frequency of an event by the total number of events. The result is a decimal or a percentage.
Here,
The total number of students who get to school by car is 90 + 120 = 210.
The relative frequency of females who get to school by car is the number of females who get to school by car divided by the total number of students at the school, which is 504:
90/504 = 0.1786
Therefore, the relative frequency of females who get to school by car in relation to the total number of students at the school is approximately 0.1786 or 17.86%.

Answer:
1. x=5
2. x=3.18
3. x=1.1
4.x=7
5.x=4/5
Step-by-step explanation:
ok so basically what the question means is one number multiplied by another number is this number. for example the first one is 7 multiplied by x (x is a variable so it represents a number) equals 35. you just have to figure out what x equals. and in my opinion, the easiest way to do that is by dividing 35 and 7, which will give you 5. so basically the equation is just 7 x 5 = 35. hope this helps :)
Answer:
1. x = 5
2. x = 3.18181818
3. x = 1.1
4. x = 7
5. x = 0.8
Step-by-step explanation:
1. 35 = 7x now if we divide both sides by 7 we get
35/7 = x
5 = x
2. 35 = 11x divide both sides by 11:
35/11 = x
3.1818181818 = x
3. 7x = 7.7 divide both sides by 7 again:
x = 7.7/7
x = 1.1
4. 0.3x = 2.1 divide by 0.3 on both sides
x = 2.1/0.3
x = 7
5. 2/5 = 1/2x first simplify: 2/5 = 0.4 1/2 = 0.5
0.4 = 0.5x divide both sides by 0.5:
0.4/0.5 = x
0.8 = x

In triangle XYZ, what is m∠XZY?
Answer:
82
Step-by-step explanation:
180-98
Answer:
X: 56°
Z: 180°
Y: 42°
Step-by-step explanation:
X is improved as 56°
To solve the "?", we have an expression:
(98° + 180°) - 180°
And that is 82°.
So Z is 180°.
To know what is Y, we have to subtract and add:
Y= 180° - (X + ?)
X is 56° and "?" is 82°
That would be 180° - (56° + 82°)
That would be 180° - 138°
Y is 42°

The following data points represent the yearly salaries of high school cheerleading coaches in Dakota county (in thousands of dollars). 41 38 36 57 43
Answer:
the MAD is 5.6 thousand
Step-by-step explanation:
First, find the mean: 41 + 38 + 36 + 57 + 43 = 215, divide it by the amount of numbers, 5, 215/5 = 43. Now that we have the mean, find the distance each number is away from it:
|41 - 43| = 2, |38 - 43| = 5, |36 - 43| = 7, |57 - 43| = 14, |43 - 43| = 0.
2 + 5 + 7 + 14 + 0 = 28, divide it by the amount of numbers to get 28/5 = 5.6

Answer:
5 and 6 look down.
7. 12%
8. 75/250 30%
Step-by-step explanation:
5. The spinner shown is not a fair spinner because sections 1 and 5 are bigger than the rest of the sections.
6. The cube is fair because you have a 1 in 6 chance of getting a number. There is not a greater chance to roll a 1 than a 4.
7. There are 3 marbles that are white out of 25. This means that the probability of getting a white marble is a 3/25 chance.
There is a 12 percent chance that you will pick a marble
8. In this problem you are doing the same thing as 7. 10/25 is 40% chance and 75/250 is 30% chance.
Jose substitutes a value for y in the equation 5y = 3y + 4
How will Jose know if the value is a solution of the equation?
Answer:
Step-by-step explanation:
Equation
5y = 3y + 4
combine like terms 3y becomes negative when moved to the left side being that its positive on the right. 4 has no variable so it stands alone on the right side.
-3y + 5y = 4
After adding a low negative to a high positive number. Turns into 2y.
2y = 4
Divide 2 on both sides to remove the number from the variable on the left.
[tex]\frac{2}{2}[/tex]y = [tex]\frac{4}{2}[/tex]
2 is canceled on the left side which gives the solution for Y.
y = 2
