in decimal form, to the nearest tenth, what is the probability that a randomly selected riverside high school student is in twelfth grade?

0.2
0.3
0.4
0.5

Answers

Answer: 0.4 which is choice C

====================================

Work Shown

Focus on the "riverside high school" row only

A = number of twelfth graders = 200

B = number of students = 500

P = probability of picking a twelfth grader

P = A/B

P = 200/500

P = 2/5

P = 0.4

The probability that a randomly selected riverside high school student is in twelfth grade is 0.4

What is probability?

The probability of an event occurring, it is calculated by the ratio of favorable cases to the total number of possible cases.

P(Event) = Favorable outcomes/ Total no. of outcomes

Now, the total no. of students studying in Riverside High School = 500

The no. of students studying in 12th grade in Riverside High School= 200

P(student in 12th grade in Riverside High School) = 200/500

P(student in 12th grade in Riverside High School) = 0.4

Hence the probability that a randomly selected riverside high school student is in twelfth grade is 0.4.

can someone help with this

Answers

Answer: Draw a line through the two points (0,2) and (3,3). See the attached image below.

How did I get these two points? The first point comes from the fact that "at the start, the height is 2 inches" meaning that x = 0 hours and y = 2 inches pair up together. This is show as point A. This is the y intercept as this is the location where the blue graph crosses the vertical y axis.

Point B is found by moving 1 unit up from point A and 3 units to the right to land on (3,3). So we have x = 3 hours and y = 3 inches pair up together.

Note: the slope is rise/run = 1/3 helping us determine the unit rate or speed in which the water is rising (ie the water is rising one-third of an inch per hour)

Some people advise that in very cold​ weather, you should keep the gas tank in your car more than half full. Lou​'s car had 6.2 gallons in the 14​-gallon tank on the coldest day of the year. Lou filled the tank with gas that cost ​$3.70 per gallon. How much did Lou spend on​ gas?

Answers

Answer:

It will cost Lou $28.86 to fill the tank

Step-by-step explanation:

Please answer this correctly

Answers

Answer:

$22.1

Step-by-step explanation:

To solve this, you must multiply the amount of the items by its cost.

This is the amount of yams in decimal form: [tex]4\frac{1}{2}[/tex] = 4.5

This is the amount of carrots in decimal form: [tex]4\frac{3}{10}[/tex] = 4.3

4.5 * 3 = 13.5

4.3 * 2 = 8.6

Now we add them together to get the total cost.

13.5 + 8.6 = 22.1

Answer:

$22.10

Step-by-step explanation:

This is simple multiplication.

1. It may help you to simplify the pound values. 4 and 1/2 is really 4.5, and 4 and 3/10 is really 4.3

2. We know what the cost is per pound, and we know how many pounds we have. We simply multiply.

4.5 pounds of yams * $3 per pound = 13.5

4.3 pounds of carrots * $2 per pound = 4.3*2 = 8.6

3. Add the values

13.5+8.6 = 22.1 = $22.10


There are 24 members of the senate on the finance committee, how many different 13 member subcommittees can be chosen to review the current energy legislation

Answers

Answer:

2496144

Step-by-step explanation:

What is the meaning of the vertical intercept in this equation? A. The plumber charges $40/h. B. The plumber charges $75/h. C. The plumber charges a flat rate of $40. D. The plumber charges a flat rate of $75.

Answers

A) The plumber charges $40/yr.

Answer:

D. The plumber charges a flat rate of $75.

Step-by-step explanation:

The vertical intercept is the point where the data intersects the vertical axis.  The vertical axis will be the dependent variable, and the horizontal axis will be the independent variable.  

In this situation, the total cost depends on how many hours the plumber works; this means that the total cost is the dependent variable, going on the vertical axis, and the number of hours is the independent variable, going on the horizontal axis.

The vertical intercept, since it is on the vertical axis, will be where the horizontal axis is 0.  In this situation, this means the cost when the plumber has been there 0 hours; this is the flat-rate fee he charges, $75.

Compare |0.525| and |−0.067|.

Answers

Final answer:

The absolute values of 0.525 and -0.067 are 0.525 and 0.067, respectively. Therefore, |0.525| is greater than |-0.067|.

Explanation:

To compare the absolute values of 0.525 and
-0.067
, we need to understand what absolute value means. The absolute value of a number is the non-negative value of that number without regard to its sign. So, for both positive and negative numbers, the absolute value is always positive or zero.

The absolute value of any number is represented by two vertical lines on either side of the number, for instance, |0.525| and |-0.067|. When we calculate these:

|0.525| is simply 0.525 since it is already a positive number.|-0.067| is 0.067 because we remove the negative sign to find the absolute value.

Comparing the two absolute values, we see that 0.525 is greater than 0.067. Therefore, |0.525| > |-0.067|.

at a clothing store 3 shirts and 8 hats cost $65. the cost for 2 shirts and 2 hats is $30. how much does each shirt and hat cost

Answers

Answer:

For the $30 2 shirts and 2 hats each one would be $7.50.

For the $65 3 shirts and 8 hats each one would be $5.90

Step-by-step explanation:


Answer:

A shirt x cost $11

and a hat y cost $4

Step-by-step explanation:

Step one

This is a word problem and we can tackle it by expressing it Mathematically

Let us initialize shirt as "x" and hat as "y"

Now

1. 3 shirts and 8 hats cost $65

Mathematically

3x+8y= 65 - - - - - - - 1

2. the cost for 2 shirts and 2 hats is

$30

Mathematically

2x + 2y = 30---------2

We now have two equations with two unknowns

We can solve for the unknown simultaneously

Step a. Multiply equation one by 1

And equation two by 4

3x+8y= 65 - - - - - - - 1

8x + 8y = 120------------2

Step b

Subtracting equation one from two

3x+8y= 65 - - - - - - - 1

-(8x + 8y = 120) ------------2

=-5x+0=-55

-5x=-55

5x=55

x=55/5

x=11

Substituting the value of x in any of the equation above to solve for y say equation 2

2(11) + 2y = 30

22+2y=30

2y= 30-22

2y= 8

y= 8/2

y= 4

Hence a shirt x cost $11

And the hat y cost $4

a cookie costs .45 and a cupcake costs .65. thirty five baked goods were sold for a total of 18.55. how many cookies were sold?

Answers

Answer:

14 cookies were baked

Step-by-step explanation:


Using a system of equations, we find that 21 cookies were sold after setting up the equations based on cost per item and total sales, and solving for the two variables representing cookies and cupcakes.

The student's question is about how many cookies were sold given that a cookie costs $0.45 and a cupcake costs $0.65, and 35 baked goods in total were sold for $18.55.

To solve this, we can set up a system of equations:

Let x represent the number of cookies sold.

Let y represent the number of cupcakes sold.

We are given two equations based on the problem statement:

x + y = 35 (since 35 total baked goods were sold)

0.45x + 0.65y = 18.55 (since the total cost of the goods sold was $18.55)

Solving the system of equations, we first multiply the first equation by 0.45:

(1) 0.45x + 0.45y = 15.75

Subtract this from the second equation:

0.20y = 2.80 (subtracting the first modified equation from the second original equation)

Divide both sides by 0.20 to find y:

y = 14

Then we substitute y into the first equation to find x:

x + 14 = 35

x = 21

So 21 cookies were sold.

Solve the quadratic equation: 2x2 + 11x − 6 = 0

Answers

Answer:

see explanation

Step-by-step explanation:

To factorise the quadratic consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x term.

product = 2 × - 6 = - 12 and sum = + 11

The factors are + 12 and - 1

Use these factors to split the middle term

2x² + 12x - x - 6 = 0 ( factor the first/second and third/fourth terms )

2x(x + 6) - 1(x + 6) = 0 (factor out (x + 6) )

(x + 6)(2x - 1) = 0

equate each factor to zero and solve for x

x + 6 = 0 ⇒ x = - 6

2x - 1 = 0 ⇒ x = [tex]\frac{1}{2}[/tex]

What is the measure of 1 in the trapezoid?



110°
55°
165°
85°

Answers

I think the answer is B. 55. Butbi would cheat to make sure.

Answer:  The correct option is (B) 55°.

Step-by-step explanation:  We are given to find the measure of angle 1 in the trapezoid shown in the figure.

We know that

one pair of sides of a trapezoid are parallel to each other.

As shown in the figure, the base of the trapezoid and its opposite side are parallel to each other.

Also, they are cut by a tranversal such that the angle 1 and the angle with measure 125°  are interior angles on the same side of the transversal.

So, the sum of the measures must be equal to 180°.

That is,

[tex]125^\circ+m\angle 1=180^\circ\\\\\Rightarrow m\angle 1=180^\circ-125^\circ\\\\\Rightarrow m\angle 1=55^\circ.[/tex]

Thus, the required measure of angle 1 is 55°.

Option (B) is CORRECT.
